Subject: solos: Check for rogue received packets

Sometimes there can be received packets with the size field set to 0xFFFF.
This seems to only occur after an FPGA or firmware upgrade.
This patch discards packets with an invalid size.

Subject: async_tx: rename zero_sum to val

'zero_sum' does not properly describe the operation of generating parity
and checking that it validates against an existing buffer.  Change the
name of the operation to 'val' (for 'validate').  This is in
anticipation of the p+q case where it is a requirement to identify the
target parity buffers separately from the source buffers, because the
target parity buffers will not have corresponding pq coefficients.

InterleaveRDn and InterleaveRUp only apply to G.dmt. The equivalents for ADSL2

useful when trying to track down instability on a line.

Subject: async_tx: kill ASYNC_TX_DEP_ACK flag

In support of inter-channel chaining async_tx utilizes an ack flag to
gate whether a dependent operation can be chained to another.  While the
flag is not set the chain can be considered open for appending.  Setting
the ack flag closes the chain and flags the descriptor for garbage
collection.  The ASYNC_TX_DEP_ACK flag essentially means "close the
chain after adding this dependency".  Since each operation can only have
one child the api now implicitly sets the ack flag at dependency
submission time.  This removes an unnecessary management burden from
clients of the api.

[ Impact: clean up and enforce one dependency per operation ]

Subject: async_tx: structify submission arguments, add scribble

Prepare the api for the arrival of a new parameter, 'scribble'.  This
will allow callers to identify scratchpad memory for dma address or page
address conversions.  As this adds yet another parameter, take this
opportunity to convert the common submission parameters (flags,
dependency, callback, and callback argument) into an object that is
passed by reference.

Also, take this opportunity to fix up the kerneldoc and add notes about
the relevant ASYNC_TX_* flags for each routine.

[ Impact: moves api pass-by-value parameters to a pass-by-reference struct ]

Subject: async_xor: permit callers to pass in a 'dma/page scribble' region

async_xor() needs space to perform dma and page address conversions.  In
most cases the code can simply reuse the struct page * array because the
size of the native pointer matches the size of a dma/page address.  In
order to support archs where sizeof(dma_addr_t) is larger than
sizeof(struct page *), or to preserve the input parameters, we utilize a
memory region passed in by the caller.

Since the code is now prepared to handle the case where it cannot
perform address conversions on the stack, we no longer need the
!HIGHMEM64G dependency in drivers/dma/Kconfig.

[ Impact: don't clobber input buffers for address conversions ]

Subject: ACPI: Make ACPI processor proc I/F depend on the ACPI_PROCFS

Now whether the ACPI processor proc I/F is registered depends on the
CONFIG_PROC. It had better depend on the CONFIG_ACPI_PROCFS.
When the CONFIG_ACPI_PROCFS is unset in kernel configuration, the
ACPI processor proc I/F won't be registered.

Subject: ACPI: processor: remove KOBJ_ONLINE/KOBJ_OFFLINE events

This patch removes the KOBJ_ONLINE/KOBJ_OFFLINE events the driver used
to generate for CPU hotplug.  As far as I know, nobody consumes these.
The driver core still generates KOBJ_ADD and KOBJ_REMOVE, of course.

We used to leave crud around if things failed in acpi_processor_start().
This patch cleans up as much as we can before returning.

Move acpi_processor_start() to just after acpi_processor_add().
A subsequent patch will merge them.

Code movement only; no functional change.

Subject: ACPI: processor: remove .start() method

This patch folds the .start() method into .add().

acpi_processor_start() is always called immediately after
acpi_processor_add(), so there's really no point in having them be
separate methods.

Subject: ACPI: memory hotplug: remove .start() method

This patch folds the .start() method into .add().

The .start() method is called in two paths: boot-time device enumeration
and run-time node addition, currently via container_device_add().  In both
cases, .start() is called immediately after .add(), so there's no reason
to make them separate methods.

This patch rearranges ec_install_handlers() and acpi_ec_start() so
acpi_ec_start() ends up just after acpi_ec_add().  A subsequent patch
will merge them.

Code movement only; no functional change.

4cbc76eadf56399cd11fb736b33c53aec9caab8c.

Richard@laptop.org was apparently using CAPACITY_LEVEL for debugging
battery/EC problems, and was upset that it was removed.  This readds it.

Grab the error code from EC_BAT_ERRCODE and let the user see it (rather
than attempting to decode it as we do with PROP_HEALTH) with a separate
error sysfs file.

 1. Downloading
 ==============
 
-kmemcheck can only be downloaded using git. If you want to write patches
-against the current code, you should use the kmemcheck development branch of
-the tip tree. It is also possible to use the linux-next tree, which also
-includes the latest version of kmemcheck.
-
-Assuming that you've already cloned the linux-2.6.git repository, all you
-have to do is add the -tip tree as a remote, like this:
-
-	$ git remote add tip git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip.git
-
-To actually download the tree, fetch the remote:
-
-	$ git fetch tip
-
-And to check out a new local branch with the kmemcheck code:
-
-	$ git checkout -b kmemcheck tip/kmemcheck
-
-General instructions for the -tip tree can be found here:
-http://people.redhat.com/mingo/tip.git/readme.txt
+As of version 2.6.31-rc1, kmemcheck is included in the mainline kernel.

Subject: power_supply: Add a charge_type property, and use it for olpc driver

This adds a new sysfs file called 'charge_type' which displays the
type of charging (unknown, n/a, trickle charge, or fast charging).

This allows things like battery diagnostics to determine what the
battery/EC is doing without resorting to changing the 'status' sysfs
output.

Subject: intel-iommu: Speed up map routines by using cached domain ASAP

We did before, in the end -- but it was at the bottom of a long stack of
functions. Add an inline wrapper get_valid_domain_for_dev() which will
use the cached one _first_ and only make the out-of-line call if it's
not already set.

This takes the average time taken for a 1-page intel_map_sg() from 5961
cycles to 4812 cycles on my Lenovo x200s test box -- a modest 20%.

Subject: NFSv4: ACL in operations 'open' and 'create' should be used

ACL in operations 'open' and 'create' is decoded but never be used.
It should be set as the initial ACL for the object according to RFC3530.
If error occurs when setting the ACL, just clear the ACL bit in the
returned attr bitmap.

Subject: SUNRPC: handle IPv6 PKTINFO when extracting destination address

PKTINFO is needed to scrape the caller's IP address off the socket so
RPC datagram replies are routed correctly.  Fill in missing pieces in
the kernel RPC server's UDP receive path to request IPv6 PKTINFO and
correctly parse the IPv6 cmsg header.

Without this patch, kernel RPC services drop all incoming requests on
UDP on IPv6.

Subject: nfsd41: use globals for DRC limits

The version 4.1 DRC memory limit and tracking variables are server wide and
session specific. Replace struct svc_serv fields with globals.
Stop using the svc_serv sv_lock.

Add a spinlock to serialize access to the DRC limit management variables which
change on session creation and deletion (usage counter) or (future)
administrative action to adjust the total DRC memory limit.

Subject: drm/mode: add the CVT algorithm in kernel space

Add the CVT algorithm in kernel space. And this function can be called to
generate the required modeline.

I copied it from the file of xserver/hw/xfree86/modes/xf86cvt.c. What I have
done is to translate it by using integer calculation. This is to avoid
the float-point calculation in kernel space.

Subject: drm/mode: add the GTF algorithm in kernel space

Add the GTF algorithm in kernel space. And this function can be called to
generate the required modeline.

I copied it from the file of xserver/hw/xfree86/modes/xf86gtf.c. What I have
done is to translate it by using integer calculation. This is to avoid
the float-point calculation in kernel space.
At the same tie I also refer to the function of fb_get_mode in
drivers/video/fbmon.c

Subject: drm/mode: get the modeline for standard timing in EDID by using
 CVT/GTF

Create the standard timing modeline by using CVT/GFT algorithm while
interpreting the EDID.

In course of interpreting the EDID, the timing level will be obtained,
which is used to determine whether the CVT/GTF algorithm is selected to
generate the modeline for the given hdisplay/vdisplay/vrefresh_rate.
In the UMS mode firstly it will check whether it can be found in
the DMT table. If it can be found, then the modeline is returned. Then the
timing_level is used to choose CVT/GTF.
As there is no DMT table, no modeline is returned when timing level
is DMT. For the other two timing levels, the CVT/GTF will be called to
generate the required standard timing modeline.

Subject: intel-iommu: Remove superfluous iova_alloc_lock from IOVA code

We only ever obtain this lock immediately before the iova_rbtree_lock,
and release it immediately after the iova_rbtree_lock. So ditch it and
just use iova_rbtree_lock.

[v2: Remove the lockdep bits this time too]

Subject: UBIFS: kill BKL

The BKL was pushed down from VFS to the file-systems. It used
to serialize mount/unmount/remount and prevented more than one
instance of the same file-system from doing
mount/umount/remount at the same time. But it is OK for UBIFS
and it does not need any additional locking for these cases.
Thus, kick the BKL out of UBIFS.

Subject: UBIFS: remove unneeded call from ubifs_sync_fs

Nowadays VFS always synchronizes all dirty inodes and pages before
calling '->sync_fs()', so remove unneeded 'generic_sync_sb_inodes()'
from 'ubifs_sync_fs()'. It used to be needed, but not any longer.

Subject: Fix memory leak in write_pool_threads

kmemleak produces the following warning

write_pool_threads() only frees nthreads on error paths, in the success case
we leak it.

Subject: nfsd41: hange from page to memory based drc limits

NFSD_SLOT_CACHE_SIZE is the size of all encoded operation responses
(excluding the sequence operation) that we want to cache.

For now, keep NFSD_SLOT_CACHE_SIZE at PAGE_SIZE. It will be reduced
when the DRC is changed from page based to memory based.

Subject: nfsd41: Use separate DRC for setclientid

Instead of trying to share the generic 4.1 reply cache code for the
CREATE_SESSION reply cache, it's simpler to handle CREATE_SESSION
separately.

The nfs41 single slot clientid DRC holds the results of create session
processing.  CREATE_SESSION can be preceeded by a SEQUENCE operation
(an embedded CREATE_SESSION) and the create session single slot cache must be
maintained.  nfsd4_replay_cache_entry() and nfsd4_store_cache_entry() do not
implement the replay of an embedded CREATE_SESSION.

The clientid DRC slot does not need the inuse, cachethis or other fields that
the multiple slot session cache uses.  Replace the clientid DRC cache struct
nfs4_slot cache with a new nfsd4_clid_slot cache.  Save the xdr struct
nfsd4_create_session into the cache at the end of processing, and on a replay,
replace the struct for the replay request with the cached version all while
under the state lock.

nfsd4_proc_compound will handle both the solo and embedded CREATE_SESSION case
via the normal use of encode_operation.

Errors that do not change the create session cache:
A create session NFS4ERR_STALE_CLIENTID error means that a client record
(and associated create session slot) could not be found and therefore can't
be changed.  NFSERR_SEQ_MISORDERED errors do not change the slot cache.

All other errors get cached.

Remove the clientid DRC specific check in nfs4svc_encode_compoundres to
put the session only if cstate.session is set which will now always be true.

Subject: nfsd41: encode replay sequence from the slot values

The sequence operation is not cached; always encode the sequence operation on
a replay from the slot table and session values. This simplifies the sessions
replay logic in nfsd4_proc_compound.

If this is a replay of a compound that was specified not to be cached, return
NFS4ERR_RETRY_UNCACHED_REP.

Subject: ioat: move to drivers/dma/ioat/

When first created the ioat driver was the only inhabitant of
drivers/dma/.  Now, it is the only multi-file (more than a .c and a .h)
driver in the directory.  Moving it to an ioat/ subdirectory allows the
naming convention to be cleaned up, and allows for future splitting of
the source files by hardware version (v1, v2, and v3).

Subject: ds2760_battery: delay power supply registration

This fixes a race condition I recently introduced with the PMOD feature
addition (cef437e3: "w1: ds2760_battery: add support for sleep mode
feature").

Postpone the call to power_supply_register() to fix it.

Subject: ds2760_battery: add rated_capacity module parameter

For systems where the ds2760 is soldered directly on the PCB, the 'rated
capacity' register is not set to anything useful.

In order to allow users to bootstrap this value, introduce a new module
parameter 'rated_capacity' and use it to write the internal EEPROM in
case the value differes from what's been given.

Subject: ds2760_battery: handle full_active_uAh == 0 case correctly

In systems where the battery monitor is not part of the battery pack and
is hence not bootstrapped with sane values, the full_active_uAh is
likely to be zero.

Handle that case by defaulting to the rated_capacity information which
can be passed to the driver using the new module parameter.

Subject: ds2760_battery: add current_accum module parameter

When connecting a ds2760 to a partly loaded battery the first time,
there must be a way to bootstrap the current_accum value. Without that,
the current capactity value is bogus until the battery is fully charged
for the first time.

Subject: power_supply: get_by_name and set_charged functionality

This adds a function that indicates that a battery is fully charged.
It also includes functions to get a power_supply device from the class
of registered devices by name reference. These can be used to find a
specific battery to call power_supply_set_battery_charged() on.

Some battery drivers might need this information to calibrate
themselves.

Subject: ds2760_battery: implement set_charged() feature

The ds2760's internal current meter is not reliable enough as it has an
inacurracy of around ~15%. Without any correction for that error, the
current accumulator is couting up all the time, even though the battery
is already fully charged and hence destroys the static information. The
longer it is connected, the worse is the aberration.

Fortunately, this can be corrected by the DS2760_CURRENT_OFFSET_BIAS
register. Using the external power_supply_set_battery_charged()
function, this register is now gauging the measurement.

A delayed work is used to debounce flaky GPIO signals and to let the
current value settle. Also see Maxim's application note AN4188.

Subject: ACPI: create Processor Aggregator Device driver

ACPI 4.0 created the logical "processor aggregator device" as
a mechinism for platforms to ask the OS to force otherwise busy
processors to enter (power saving) idle.

The intent is to lower power consumption to ride-out
transient electrical and thermal emergencies,
rather than powering off the server.

On platforms that can save more power/performance via P-states,
the platform will first exhaust P-states before forcing idle.
However, the relative benefit of P-states vs. idle states
is platform dependent, and thus this driver need not know
or care about it.

This driver does not use the kernel's CPU hot-plug mechanism
because after the transient emergency is over, the system must
be returned to its normal state, and hotplug would permanently
break both cpusets and binding.

So to force idle, the driver creates a power saving thread.
The scheduler will migrate the thread to the preferred CPU.
The thread has max priority and has SCHED_RR policy,
so it can occupy one CPU.  To save power, the thread will
invoke the deep C-state entry instructions.

To avoid starvation, the thread will sleep 5% of the time
time for every second (current RT scheduler has threshold
to avoid starvation, but if other CPUs are idle,
the CPU can borrow CPU timer from other,
which makes the mechanism not work here)

Vaidyanathan Srinivasan has proposed scheduler enhancements
to allow injecting idle time into the system.  This driver doesn't
depend on those enhancements, but could cut over to them
when they are available.

Peter Z. does not favor upstreaming this driver until
the those scheduler enhancements are in place.  However,
we favor upstreaming this driver now because it is useful
now, and can be enhanced over time.

Subject: fat/nls: Fix handling of utf8 invalid char

With utf8 option, vfat allowed the duplicated filenames.

Normal nls returns -EINVAL for invalid char. But utf8s_to_utf16s()
skipped the invalid char historically.

So, this changes the utf8s_to_utf16s() directly to return -EINVAL for
invalid char, because vfat is only user of it.

mkdir /mnt/fatfs
FILENAME=`echo -ne "invalidutf8char_\\0341_endofchar"`
echo "Using filename: $FILENAME"
dd if=/dev/zero of=fatfs bs=512 count=128
mkdosfs -F 32 fatfs
mount -o loop,utf8 fatfs /mnt/fatfs
touch "/mnt/fatfs/$FILENAME"
umount /mnt/fatfs
mount -o loop,utf8 fatfs /mnt/fatfs
touch "/mnt/fatfs/$FILENAME"
ls -l /mnt/fatfs
umount /mnt/fatfs

----  And the output is:

Using filename: invalidutf8char_\0341_endofchar
128+0 records in
128+0 records out

Subject: vfat: change the default from shortname=lower to shortname=mixed

Because, with "shortname=lower", copying one FAT filesystem tree to
another FAT filesystem tree using Linux results in semantically
different filesystems. (E.g.: Filenames which were once "all
uppercase" are now "all lowercase").

So, this changes the default of "shortname=lower" to "shortname=mixed".

Subject: itimers: Fix periodic tics precision

Measure ITIMER_PROF and ITIMER_VIRT timers interval error
between real ticks and requested by user. Take it into account
when scheduling next tick.

This patch introduce possibility where time between two
consecutive tics is smaller then requested interval, it
preserve however dependency that n tick is generated not
earlier than n*interval time - counting from the beginning of
periodic signal generation.

Subject: cputime: Optimize jiffies_to_cputime(1)

For powerpc with CONFIG_VIRT_CPU_ACCOUNTING
jiffies_to_cputime(1) is not compile time constant and run time
calculations are quite expensive. To optimize we use
precomputed value. For all other architectures is is
preprocessor definition.

Subject: drm: Remove the unused prefix in DRM_DEBUG_KMS/DRIVER/MODE

We will have to add a prefix when using the macro defintion of DRM_DEBUG_KMS
/DRM_DEBUG_DRIVER/MODE. It is not convenient. We should use the DRM_NAME
as default prefix.
So remove the prefix in the macro definition of DRM_DEBUG_KMS/DRIVER/MODE.

Subject: drm: Remove the macro defintion of DRM_DEBUG_MODE

Two macro definitions of DRM_DEBUG_KMS/MODE can be used to add the debug
info related with KMS. It is confusing.
So remove the macro definition of DRM_DEBUG_MODE. Instead it can be replaced
by the DRM_DEBUG_KMS.

From 2066facca4c7dfe9f5068ece0200a4dbf10f49e1 Mon Sep 17 00:00:00 2001
From: Francisco Jerez <currojerez@riseup.net>
Date: Sun, 2 Aug 2009 04:19:17 +0200
Subject: drm/kms: slave encoder interface.

Define some helper functions to make easier to detach a KMS encoder
implementation from the drm module of the GPU it's used in. This is
mainly useful for some external I2C encoders known to be present on
cards with GPUs from several different manufacturers.

Subject: drm: Define DRM_MODE_CONNECTOR_TV

The existing TV connector types are often unsuitable either because
there is no way to probe them until they're actually plugged in or
because they can change during run time (e.g. 7-pin DIN connectors
that behave as S-Video, Component, Composite or SCART depending on the
adaptor plugged in).

Subject: intel-iommu: Cope with broken HP DC7900 BIOS

Yet another reason why trusting this stuff to the BIOS was a bad idea.
The HP DC7900 BIOS reports an iommu at an address which just returns all
ones, when VT-d is disabled in the BIOS.

Fix up the missing iounmap in the error paths while we're at it.

'loose' was a mis-spelling of 'lose', and even that wasn't a good
word choice.
So give this function a more useful name.

Subject: sunrpc/cache: make sure deferred requests eventually get revisited.

While deferred requests normally get revisited quite quickly,
it is possible for a request to remain in the deferral queue
when the cache item is discarded.  We can easily make sure that
doesn't happen by calling cache_revisit_request just before
the final 'put'.

Also there is a small chance that a race would cause one thread to
defer a request against a cache item while another thread is failing
to queue an upcall for that item.  So when the upcall fails, make
sure to revisit all deferred requests.

Subject: intel-iommu: Unify hardware and software passthrough support

This makes the hardware passthrough mode work a lot more like the
software version, so that the behaviour of a kernel with 'iommu=pt'
is the same whether the hardware supports passthrough or not.

In particular:
 - We use a single si_domain for the pass-through devices.
 - 32-bit devices can be taken out of the pass-through domain so that
   they don't have to use swiotlb.
 - Devices will work again after being removed from a KVM guest.
 - A potential oops on OOM (in init_context_pass_through()) is fixed.

Subject: sunrpc/cache: recheck cache validity after cache_defer_req

If cache_defer_req did not leave the request on a queue, then it could
possibly have waited long enough that the cache became valid.  So check the
status after the call.

Since commit 19943b0e30b05d42e494ae6fef78156ebc8c637e ('intel-iommu:
Unify hardware and software passthrough support'), hardware passthrough
mode will do the same as software passthrough mode was doing -- it'll
still use the IOMMU normally for devices which can't address all of
memory. This means that we don't need to bother with swiotlb.

Subject: UBI: amend NOR flash pre-erase quirk

In case of NOR flash, UBI zeroes EC and VID headers' magic,
in order to detect interrupted erasures. It first zeroes out
the EC magic, then VID magic. However, if a power cut happens
in between, we'll end up with a corrupted EC header and a valid
VID header, in which case UBI accepts the PEB, but prints a
warning. This patch makes sure we first zero out the VID
magic, then the EC magic, not vice versa. This is just a
small amendment to prevent warning messages.

Subject: UBI: print a warning if too many PEBs are corrupted

There was a bug report recently where UBI prints:

UBI error: ubi_attach_mtd_dev: failed to attach by scanning, error -22

error messages and refuses to attach a PEB. It turned out to be a
buggy flash driver which returned garbage to almost every UBI read.
This patch makes UBI print a better message in such cases. Namely,
if UBI finds 8 or more corrupted PEBs, it prints a warning and
lists the corrupted PEBs.

Subject: UBI: eliminate possible undefined behaviour

The assignment to pos when rb is finally NULL is undefined behaviour.
Upon seeing that assignment, GCC may assume that rb is not NULL, and
the loop condition ``rb'' may be optimised away.

Subject: UBI: improve NOR flash erasure quirk

More testing of NOR flash against power cuts showed that sometimes
eraseblocks may be unwritable, and we cannot really invalidate
them before erasure. But in this case the eraseblock probably
contains garbage anyway, and we do not have to invalidate the
headers. This assumption might be not true, but this is at least
what I have observed. So if we cannot invalidate the headers,
we make sure that the PEB does not contain valid VID header.
If this is true, everything is fine, otherwise we panic.

Subject: ARM: 5666/1: Revamped U300 padmux API

This abstracts the hackish padmux API on the U300 platform into
something more manageable. It provides a way for drivers to
activate/deactivate a certain padmux setting. It will also switch
the users of the old API over to using the new style, pushing
muxing into the apropriate setup files.

From c7c8c78fdf6e9bd65d8ee879115dc2cd5d9fd0dc Mon Sep 17 00:00:00 2001
From: Linus Walleij <linus.walleij@stericsson.com>
Date: Fri, 14 Aug 2009 10:59:05 +0100
Subject: ARM: 5667/3: U300 SSP/SPI board setup and test

This adds a U300 board configuration for the PL022 SSP/SPI
PrimeCell driver recently merged to the 2.6.31-rc series.
Further it adds a dummy loopback SPI chip that can be used
for testing the SPI functionality on a running system using
the loopback mode of PL022.

From 6be2a0cacc1ed6899a53172e2e9b7a3587be0bea Mon Sep 17 00:00:00 2001
From: Linus Walleij <linus.walleij@stericsson.com>
Date: Thu, 13 Aug 2009 21:42:01 +0100
Subject: ARM: 5668/2: U300 I2C board setup

This sets up the U300 I2C subdevices so that the AB3100
analog baseband ASIC is properly detected and also the
camera devices in the U335 reference design get properly
registered.

From 9e2a7e6f5f1091965c78e01e87af05607bbf937f Mon Sep 17 00:00:00 2001
From: Dan Williams <dan.j.williams@intel.com>
Date: Tue, 18 Aug 2009 13:47:30 -0700
Subject: iop33x: update defconfig (default atu to on)

By default the iop3xx configurations are set to boot the platforms over
an nfs root configuration.  Since commit c34002c1 "iop: unconditionally
initialize the ATU on platforms known to be 'hosts'" this configuration
also requires iop3xx_init_atu=y to be specified on the kernel command
line.

Subject: iop3xx: ATU and PCI memory configuration corrected

There are two 64 MB outbound memory windows at bus addresses
0x80000000..0x83ffffff and 0x84000000..0x87ffffff for PCI
memory. Currently, on iop32x, only the lower window is available for
allocations, limiting the available space to 64 MB. On iop33x the full
128 MB can be allocated, but the translation value is wrong for the
upper window.

The patch enables the full 128 MB space on iop32x and corrects the
initialization of OMWTVR1. Redundant definitions are deleted. Tested
using a Thecus N2100 board with a graphics adapter in the expansion
slot. Both windows are in use:

  00:05.0 VGA compatible controller: XGI Technology Inc. (eXtreme Graphics
  Innovation) Volari Z7 (prog-if 00 [VGA controller])
  [...]
	Region 0: Memory at 80000000 (32-bit, prefetchable) [size=64M]
	Region 1: Memory at 84080000 (32-bit, non-prefetchable) [size=256K]

Just a DRM_MASTER flag is sufficient here, though maybe this call is

Subject: drm: clarify scaling property names

Now that we're using the scaling property in the Intel driver I noticed
that the names were a bit confusing.  I've corrected them according to
our discussion on IRC and the mailing list, though I've left out
potential new additions for a new scaling property with an integer (or
two) for the scaling factor.  None of the drivers implement that today,
but if someone wants to do it, I think it could be done with the
addition of a single new type and a new property to describe the
scaling factor in the X and Y directions.

Subject: drm/ttm: optimize bo_kmap_type values

A micro-optimization on the function ttm_kmap_obj_virtual().

By defining the values of enum ttm_bo_kmap_obj::bo_kmap_type to have a
bit indicating iomem, size of the function ttm_kmap_obj_virtual() will be
reduced by 16 bytes on x86_64 (gcc 4.1.2).

ttm_kmap_obj_virtual() may be heavily used, when buffer objects are
accessed via wrappers, that work for both kinds of memory addresses:
iomem cookies and kernel virtual.

From 5fd9cbad3a4ae82c83c55b9c621d156c326724ef Mon Sep 17 00:00:00 2001
From: Thomas Hellstrom <thellstrom@vmware.com>
Date: Mon, 17 Aug 2009 16:28:39 +0200
Subject: drm/ttm: Memory accounting rework.

Use inclusive zones to simplify accounting and its sysfs representation.
Use DMA32 accounting where applicable.

Add a sysfs interface to make the heuristically determined limits
readable and configurable.

From a987fcaa805fcb24ba885c2e29fd4fdb6816f08f Mon Sep 17 00:00:00 2001
From: Thomas Hellstrom <thellstrom@vmware.com>
Date: Tue, 18 Aug 2009 16:51:56 +0200
Subject: ttm: Make parts of a struct ttm_bo_device global.

Common resources, like memory accounting and swap lists should be
global and not per device. Introduce a struct ttm_bo_global to
accomodate this, and register it with sysfs. Add a small sysfs interface
to return the number of active buffer objects.

From 132032274a594ee9ffb6b9c9e2e9698149a09ea9 Mon Sep 17 00:00:00 2001
From: David Woodhouse <dwmw2@infradead.org>
Date: Mon, 3 Aug 2009 12:40:27 +0100
Subject: USB: Work around BIOS bugs by quiescing USB controllers earlier

We are seeing a number of crashes in SMM, when VT-d is enabled while
'Legacy USB support' is enabled in various BIOSes.

The BIOS is supposed to indicate which addresses it uses for DMA in a
special ACPI table ("RMRR"), so that we can punch a hole for it when we
set up the IOMMU.

The problem is, as usual, that BIOS engineers are totally incompetent.
They write code which will crash if the DMA goes AWOL, and then they
either neglect to provide an RMRR table at all, or they put the wrong
addresses in it. And of course they don't do _any_ QA, since that would
take too much time away from their crack-smoking habit.

The real fix, of course, is for consumers to refuse to buy motherboards
which only have closed-source firmware available. If we had _open_
firmware, bugs like this would be easy to fix.

Since that's something I can only dream about, this patch implements an
alternative -- ensuring that the USB controllers are handed off from the
BIOS and quiesced _before_ the IOMMU is initialised. That would have
been a much better design than this RMRR nonsense in the first place, of
course. The bootloader has no business doing DMA after the OS has booted
anyway.

Subject: sunrpc: add routine for comparing addresses

lockd needs these sort of routines, as does the NFSv4 callback code.

Move lockd's routines into common code and rename them so that they can
be used by others.

Subject: nfsd: convert nfs4_cb_conn struct to hold address in sockaddr_storage

...rather than as a separate address and port fields. This will be
necessary for implementing callbacks over IPv6. Also, convert
gen_callback to use the standard rpcuaddr2sockaddr routine rather than
its own private one.

Subject: nfsd: populate sin6_scope_id on callback address with scopeid from
 rq_addr on SETCLIENTID call

When a SETCLIENTID call comes in, one of the args given is the svc_rqst.
This struct contains an rq_addr field which holds the address that sent
the call. If this is an IPv6 address, then we can use the sin6_scope_id
field in this address to populate the sin6_scope_id field in the
callback address.

AFAICT, the rq_addr.sin6_scope_id is non-zero if and only if the client
mounted the server's link-local address.

This is often because si_domain_init lacks a __init
annotation or the annotation of si_domain_work_fn is wrong.

Subject: intel-iommu: iommu init error path bug fixes

The kcalloc() failure path in iommu_init_domains() calls
free_dmar_iommu(), which assumes that ->domains, ->domain_ids,
and ->lock have been properly initialized.

Add checks in free_[dmar]_iommu to not use ->domains,->domain_ids
if not alloced. Move the lock init to prior to the kcalloc()'s,
so it is valid in free_context_table() when free_dmar_iommu() invokes
it at the end.

Patch based on iommu-2.6,

Subject: nfsd: Fix unnecessary deny bits in NFSv4 ACL

The group deny entries end up denying tcy even though tcy was just
allowed by the allow entry. This appears to be due to:
	ace->access_mask = mask_from_posix(deny, flags);
instead of:
	ace->access_mask = deny_mask_from_posix(deny, flags);

Denying a previously allowed bit has no effect, so this shouldn't affect
behavior, but it's ugly.

Subject: knfsd: Replace lock_kernel with a mutex in nfsd pool stats.

lock_kernel() in knfsd was replaced with a mutex. The later
commit 03cf6c9f49a8fea953d38648d016e3f46e814991 ("knfsd:
add file to export stats about nfsd pools") did not follow
that change. This patch fixes the issue.

Also move the get and put of nfsd_serv to the open and close methods
(instead of start and stop methods) to allow atomic check and increment
of reference count in the open method (where we can still return an
error).

Subject: sunrpc: reply AUTH_BADCRED to RPCSEC_GSS with unknown service

When an RPC message is received with RPCSEC_GSS with an unknown service
(not RPC_GSS_SVC_NONE, RPC_GSS_SVC_INTEGRITY, or RPC_GSS_SVC_PRIVACY),
svcauth_gss_accept() returns AUTH_BADCRED, but svcauth_gss_release()
subsequently drops the response entirely, discarding the error.

Fix that so the AUTH_BADCRED error is returned to the client.

Subject: drm: GEM handles are u32, not int

Several functions in the GEM kernel API used int as handle type, but
user API has it __u32 which is also the intended type.

Replace int with u32.

Subject: ACPICA: Add 64-bit support to acpi_read and acpi_write

Needed by drivers for new ACPi tables.  Internal versions of
these functions still use 32-bit max transfers, in order to
minimize disruption and stack use for the standard ACPI registers
(FADT-based).

Subject: ACPICA: Major update for acpi_get_object_info external interface

Completed a major update for the acpi_get_object_info external interface.
Changes include:
 - Support for variable, unlimited length HID, UID, and CID strings
 - Support Processor objects the same as Devices (HID,UID,CID,ADR,STA, etc.)
 - Call the _SxW power methods on behalf of a device object
 - Determine if a device is a PCI root bridge
 - Change the ACPI_BUFFER parameter to ACPI_DEVICE_INFO.
These changes will require an update to all callers of this interface.
See the ACPICA Programmer Reference for details.

Also, update all invocations of acpi_get_object_info interface

Subject: ACPICA: Fix possible memory leak in nspredef

Fixed a possible leak when an attempt is made to repair a return
object.  The only current repair is an automatic buffer to string
conversion.

Handler was never invoked. Now invoked if/when host node is deleted.
Data object was not automatically deleted when host node was deleted.
Interface to handler had an unused parameter, removed it.

Subject: ACPICA: Dump table header - suppress output of non-printable
 characters

Function acpi_tb_print_table_header. Some ACPI tables contain
non-printable characters in one of the string fields of the the
header - Signature, OemId, OemTableId, or CompilerId. Invalid
characters are replaced by '?'. ACPICA BZ 788.

Subject: ACPICA: Fix: Predefined object repair executed only once

This fixes a problem where the code that attempts to repair/convert
an object of incorrect type is only executed on the first time the
predefined method is called. The mechanism that disables warnings
on subsequent calls was interfering with the repair mechanism.
ACPICA BZ 781.

Subject: ACPICA: fix leak of acpi_os_validate_address

http://bugzilla.kernel.org/show_bug.cgi?id=13620

If the dynamic region is created and added to resource list over and over again,
it has the potential to be a memory leak by growing the list every time.

This patch fixes the memory leak, as below

1) add a new field "count" to struct acpi_res_list.

   When inserting, if the region(addr, len) is already in the resource
   list, we just increase "count", otherwise, the region is inserted
   with count=1.

   When deleting, the "count" is decreased, if it's decreased to 0,
   the region is deleted from the resource list.

   With "count", the region with same address and length can only be
   inserted to the resource list once, so prevent potential memory leak.

2) add a new function acpi_os_invalidate_address, which is called when
   region is deleted.

Subject: nfsd41: renew_client must be called under the state lock

Until we work out the state locking so we can use a spin lock to protect
the cl_lru, we need to take the state_lock to renew the client.

Subject: sunrpc: move the close processing after do recvfrom method

sunrpc: "Move close processing to a single place"
(d7979ae4a050a45b78af51832475001b68263d2a) moved the
close processing before the recvfrom method. This may
cause the close processing never to execute. So this
patch moves it to the right place.

Subject: nfsd4: remove ACE4_IDENTIFIER_GROUP flag from GROUP@ entry

RFC 3530 says "ACE4_IDENTIFIER_GROUP flag MUST be ignored on entries
with these special identifiers.  When encoding entries with these
special identifiers, the ACE4_IDENTIFIER_GROUP flag SHOULD be set to
zero."  It really shouldn't matter either way, but the point is that
this flag is used to distinguish named users from named groups (since
unix allows a group to have the same name as a user), so it doesn't
really make sense to use it on a special identifier such as this.)

Subject: nfsd41: expand solo sequence check

Compounds consisting of only a sequence operation don't need any
additional caching beyond the sequence information we store in the slot
entry.  Fix nfsd4_is_solo_sequence to identify this case correctly.

The additional check for a failed sequence in nfsd4_store_cache_entry()
is redundant, since the nfsd4_is_solo_sequence call lower down catches
this case.

The final ce_cachethis set in nfsd4_sequence is also redundant.

Subject: eeepc-laptop: don't touch the pci slot if it was claimed by a
 different driver

The whole point of registering as a PCI hotplug driver was to prevent
conflict with pciehp.  At the moment it happens to work because
eeepc-laptop is loaded first, but it doesn't work the other way round.
If pciehp is loaded first then we fail to claim the slot - we need to
respect this and not handle hotplug events.

Subject: eeepc-laptop: use a mutex to serialize pci hotplug (resume vs.
 notify)

Commit d0265f0 "eeepc-laptop: fix hot-unplug on resume" used a workqueue
to protect pci hotplug against multiple simultaneous calls during
resume.  It seems to work, but a mutex would be more appropriate.

This is in preparation to fix the potential pci hotplug race on unload.

Subject: eeepc-laptop: fix pci hotplug race on load and unload

Wifi rfkill state changes can race with pci hotplug cleanup.  A simple
fix is to refresh the hotplug state just before deregistering the pci
hotplug slot.

There is also potential for a hotplug notification to fire too early
during setup, while the structures it uses are still being initialised.
(This could only happen if the BIOS performs hotplug itself; a bug
triggered by removing the battery while hibernated).  Avoid this by
registering the notifier later.  The same refresh mechanism is used
to handle rfkill state changes which can now race with registration.

Subject: eeepc-laptop: fix ordering of init and exit functions

1. input and backlight devices were registered after acpi notifications
   are enabled.  This left a window where eeepc_hotk_notify() might
   find these devices in an inconsistent (half-initialized) state.

-> Move all device registration into eeepc_hotk_add(), which is called
   before enabling acpi notifications.

2. input and backlight devices were unregistered before acpi
   notifications are disabled.  This left a window where
   eeepc_hotk_notify() might find these devices in an inconsistent
   (half-destroyed) state.

-> Move all device unregistration into eeepc_hotk_remove(), which is
   called after disabling acpi notifications.

3. The acpi driver was not freed if an error occured further down in
   eeepc_laptop_init().

-> The rest of eeepc_laptop_init() has been moved to eeepc_hotk_add(),
   so this is no longer a problem.

4. The acpi driver was unregistered before the platform driver.  This
   left a window where a sysfs access could attempt to read the ehotk
   structure after it had been freed by eeepc_hotk_remove().

-> The acpi driver is now unregistered as the last step in
   eeepc_laptop_exit(), so this is no longer a problem.

Subject: eeepc-laptop: make input device a child of the platform device

Sysfs showed the ehotk input device as a "virtual" device - lies!
The input device is provided by a physical device, the eeepc platform.

This requires that we move the creation of the input device to come
after platform device is created.  Input initialization is moved from
ehotk_check() [sic] to a new function called eeepc_input_init().  This
brings the input device into line with the other eeepc-laptop devices.

Also, refuse to load if we fail to register the input device.

Subject: eeepc-laptop: switch to dev_pm_ops

This also involves switching the resume handler from the acpi device
to the platform device.  Using the more fine grained handlers allows
two improvements:

1. We only need to recheck rfkill state after resume from hibernation.

2. The wireless LED workaround accounts for up to 1.1s out of 1.7s
resuming devices (when wireless is enabled).  We can limit the
workaround to thaw(), so that it only delays suspend to disk.

The workaround is only likely to help when hibernation is aborted.
Suspend to ram cannot be aborted by the user.  Device suspend errors may
well happen before eeepc-laptop would even be frozen.  Suspend errors
which happen after that could be pretty funky anyway.

Subject: asus-laptop: Add support for Keyboard backlight

Add support for keyboard backlight found in Asus U50VG.

The SMC driver for the Apples does it via LED. To be
consistent with that we create /sys/class/leds/asus::kbd_backlight/
to control the keyboard backlight.

SLKB and GLKB are used to get/set the backlight. On
the U50VG is supports 4 brightness level, but this may
change with other models.

SLKB take a 8 bit integer where the higher bit is used
to toggle the backlight, and the over 7 bits control the
brightness level.

+Asus Laptop Extras
+
+Version 0.1
+August 6, 2009
+
+Corentin Chary <corentincj@iksaif.net>
+http://acpi4asus.sf.net/
+
+ This driver provides support for extra features of ACPI-compatible ASUS laptops.
+ It may also support some MEDION, JVC or VICTOR laptops (such as MEDION 9675 or
+ VICTOR XP7210 for example). It makes all the extra buttons generate standard
+ ACPI events that go through /proc/acpi/events and input events (like keyboards).
+ On some models adds support for changing the display brightness and output,
+ switching the LCD backlight on and off, and most importantly, allows you to
+ blink those fancy LEDs intended for reporting mail and wireless status.
+
+This driver supercedes the old asus_acpi driver.
+
+Requirements
+------------
+
+  Kernel 2.6.X sources, configured for your computer, with ACPI support.
+  You also need CONFIG_INPUT and CONFIG_ACPI.
+
+Status
+------
+
+ The features currently supported are the following (see below for
+ detailed description):
+
+ - Fn key combinations
+ - Bluetooth enable and disable
+ - Wlan enable and disable
+ - GPS enable and disable
+ - Video output switching
+ - Ambient Light Sensor on and off
+ - LED control
+ - LED Display control
+ - LCD brightness control
+ - LCD on and off
+
+ A compatibility table by model and feature is maintained on the web
+ site, http://acpi4asus.sf.net/.
+
+Usage
+-----
+
+  Try "modprobe asus_acpi". Check your dmesg (simply type dmesg). You should
+  see some lines like this :
+
+      Asus Laptop Extras version 0.42
+        L2D model detected.
+
+  If it is not the output you have on your laptop, send it (and the laptop's
+  DSDT) to me.
+
+  That's all, now, all the events generated by the hotkeys of your laptop
+  should be reported in your /proc/acpi/event entry. You can check with
+  "acpi_listen".
+
+  Hotkeys are also reported as input keys (like keyboards) you can check
+  which key are supported using "xev" under X11.
+
+  You can get informations on the version of your DSDT table by reading the
+  /sys/devices/platform/asus-laptop/infos entry. If you have a question or a
+  bug report to do, please include the output of this entry.
+
+LEDs
+----
+
+  You can modify LEDs be echoing values to /sys/class/leds/asus::*/brightness :
+    echo 1 >  /sys/class/leds/asus::mail/brightness
+  will switch the mail LED on.
+  You can also know if they are on/off by reading their content and use
+  kernel triggers like ide-disk or heartbeat.
+
+Backlight
+---------
+
+  You can control lcd backlight power and brightness with
+  /sys/class/backlight/asus-laptop/. Brightness Values are between 0 and 15.
+
+Wireless devices
+---------------
+
+  You can turn the internal Bluetooth adapter on/off with the bluetooth entry
+  (only on models with Bluetooth). This usually controls the associated LED.
+  Same for Wlan adapter.
+
+Display switching
+-----------------
+
+  Note: the display switching code is currently considered EXPERIMENTAL.
+
+  Switching works for the following models:
+    L3800C
+    A2500H
+    L5800C
+    M5200N
+    W1000N (albeit with some glitches)
+    M6700R
+    A6JC
+    F3J
+
+  Switching doesn't work for the following:
+    M3700N
+    L2X00D (locks the laptop under certain conditions)
+
+  To switch the displays, echo values from 0 to 15 to
+  /sys/devices/platform/asus-laptop/display. The significance of those values
+  is as follows:
+
+  +-------+-----+-----+-----+-----+-----+
+  | Bin   | Val | DVI | TV  | CRT | LCD |
+  +-------+-----+-----+-----+-----+-----+
+  + 0000  +   0 +     +     +     +     +
+  +-------+-----+-----+-----+-----+-----+
+  + 0001  +   1 +     +     +     +  X  +
+  +-------+-----+-----+-----+-----+-----+

+  + 0110  +   6 +     +  X  +  X  +     +
+  +-------+-----+-----+-----+-----+-----+
+  + 0111  +   7 +     +  X  +  X  +  X  +
+  +-------+-----+-----+-----+-----+-----+
+  + 1000  +   8 +  X  +     +     +     +
+  +-------+-----+-----+-----+-----+-----+
+  + 1001  +   9 +  X  +     +     +  X  +
+  +-------+-----+-----+-----+-----+-----+
+  + 1010  +  10 +  X  +     +  X  +     +
+  +-------+-----+-----+-----+-----+-----+
+  + 1011  +  11 +  X  +     +  X  +  X  +
+  +-------+-----+-----+-----+-----+-----+
+  + 1100  +  12 +  X  +  X  +     +     +
+  +-------+-----+-----+-----+-----+-----+
+  + 1101  +  13 +  X  +  X  +     +  X  +
+  +-------+-----+-----+-----+-----+-----+
+  + 1110  +  14 +  X  +  X  +  X  +     +
+  +-------+-----+-----+-----+-----+-----+
+  + 1111  +  15 +  X  +  X  +  X  +  X  +
+  +-------+-----+-----+-----+-----+-----+
+
+  In most cases, the appropriate displays must be plugged in for the above
+  combinations to work. TV-Out may need to be initialized at boot time.
+
+  Debugging:
+  1) Check whether the Fn+F8 key:
+     a) does not lock the laptop (try disabling CONFIG_X86_UP_APIC or boot with
+        noapic / nolapic if it does)
+     b) generates events (0x6n, where n is the value corresponding to the
+        configuration above)
+     c) actually works
+     Record the disp value at every configuration.
+  2) Echo values from 0 to 15 to /sys/devices/platform/asus-laptop/display.
+     Record its value, note any change. If nothing changes, try a broader range,
+     up to 65535.
+  3) Send ANY output (both positive and negative reports are needed, unless your
+     machine is already listed above) to the acpi4asus-user mailing list.
+
+  Note: on some machines (e.g. L3C), after the module has been loaded, only 0x6n
+  events are generated and no actual switching occurs. In such a case, a line
+  like:
+
+    echo $((10#$arg-60)) > /sys/devices/platform/asus-laptop/display
+
+  will usually do the trick ($arg is the 0000006n-like event passed to acpid).
+
+  Note: there is currently no reliable way to read display status on xxN
+  (Centrino) models.
+
+LED display
+-----------
+
+  Some models like the W1N have a LED display that can be used to display
+  several informations.
+
+  LED display works for the following models:
+    W1000N
+    W1J
+
+  To control the LED display, use the following :
+
+    echo 0x0T000DDD > /sys/devices/platform/asus-laptop/
+
+  where T control the 3 letters display, and DDD the 3 digits display,
+  according to the tables below.
+
+         DDD (digits)
+         000 to 999 = display digits
+         AAA        = ---
+         BBB to FFF = turn-off
+
+         T  (type)
+         0 = off
+         1 = dvd
+         2 = vcd
+         3 = mp3
+         4 = cd
+         5 = tv
+         6 = cpu
+         7 = vol
+
+  For example "echo 0x01000001 >/sys/devices/platform/asus-laptop/ledd"
+  would display "DVD001".
+
+Driver options:
+---------------
+
+ Options can be passed to the asus-laptop driver using the standard
+ module argument syntax (<param>=<value> when passing the option to the
+ module or asus-laptop.<param>=<value> on the kernel boot line when
+ asus-laptop is statically linked into the kernel).
+
+	     wapf: WAPF defines the behavior of the Fn+Fx wlan key
+		   The significance of values is yet to be found, but
+		   most of the time:
+		   - 0x0 should do nothing
+		   - 0x1 should allow to control the device with Fn+Fx key.
+		   - 0x4 should send an ACPI event (0x88) while pressing the Fn+Fx key
+		   - 0x5 like 0x1 or 0x4
+
+ The default value is 0x1.
+
+Unsupported models
+------------------
+
+ These models will never be supported by this module, as they use a completely
+ different mechanism to handle LEDs and extra stuff (meaning we have no clue
+ how it works):
+
+ - ASUS A1300 (A1B), A1370D
+ - ASUS L7300G
+ - ASUS L8400
+
+Patches, Errors, Questions:
+--------------------------
+
+ I appreciate any success or failure
+ reports, especially if they add to or correct the compatibility table.
+ Please include the following information in your report:
+
+ - Asus model name
+ - a copy of your ACPI tables, using the "acpidump" utility
+ - a copy of /sys/devices/platform/asus-laptop/infos
+ - which driver features work and which don't
+ - the observed behavior of non-working features
+
+ Any other comments or patches are also more than welcome.

From e5f69d6ef7a6b0dbad8d4c00d83009960be02155 Mon Sep 17 00:00:00 2001
From: Bob Moore <robert.moore@intel.com>
Date: Fri, 24 Jul 2009 11:03:09 +0800
Subject: ACPICA: Add repair for predefined methods that return nested packages

Fixes a problem where a predefined method is defined to return
a variable-length Package of sub-packages. If the length is one,
the BIOS code occasionally creates a simple single package with
no sub-packages. This code attempts to fix the problem by wrapping
a new package object around the existing package. ACPICA BZ 790.

Subject: ACPICA: ACPI 4.0 : Add new return package type, restructure module.

Added one new package type, a package that contains a revision number and
a variable number of sub-packages. Restructured the module to
put the sub-package list traversal in a separate function.

Subject: ACPICA: Add support for module-level executable AML code

Add limited support for executable AML code that exists outside
of any control method. This type of code has been illegal since
ACPI 2.0.  The code must exist in an If/Else/While block. All AML
tables are supported, including tables that are dynamically loaded.
ACPICA BZ 762.

Subject: ACPI: Move definition of PREFIX from acpi_bus.h to internal..h

Linux/ACPI core files using internal.h all PREFIX "ACPI: ",
however, not all ACPI drivers use/want it -- and they
should not have to #undef PREFIX to define their own.

Add GPL commment to internal.h while we are there.

This does not change any actual console output,
asside from a whitespace fix.

 acpi_table_parse_entries()

Allow consumers of the acpi_table_parse()/acpi_table_parse_entries() API
to gracefully handle the acpi_disabled=1 case via return value
rather than checking the global flag themselves.

Subject: SFI: Simple Firmware Interface - MAINTAINERS, Kconfig

CONFIG_SFI=y enables the kernel to boot and run optimally
on platforms that support the Simple Firmware Interface.

Thanks to Jacob Pan for prototyping the initial Linux SFI support,
and to Feng Tang for Linux bring-up and debug both in emulation
and on Moorestown hardware.

See http://simplefirmware.org for more information on SFI.

+	The Simple Firmware Interface (SFI) provides a lightweight method
+	for platform firmware to pass information to the operating system
+	via static tables in memory.  Kernel SFI support is required to
+	boot on SFI-only platforms.  Currently, all SFI-only platforms are
+	based on the 2nd generation Intel Atom processor platform,
+	code-named Moorestown.
+
+	For more information, see http://simplefirmware.org
+
+	Say 'Y' here to enable the kernel to boot on SFI-only platforms.

Subject: ACPI: Handle CONFIG_ACPI=n better from linux/acpi.h

linux/acpi.h is the top level header for interfacing
with the ACPI sub-system, so acpi_disabled should be
up there instead of down in asm/acpi.h -- particularly
since asm/acpi.h doesn't exist for all architectures.

Same story for acpi_table_parse(), which is a top-level
API to Linux/ACPI.

This is necessary for building some code that
used to always depend on CONFIG_ACPI=y, but will soon
also need to build with CONFIG_ACPI=n.

Subject: SFI: create linux/sfi.h

include/linux/include/sfi.h defines everything that customers
of SFI need to know in order to use the SFI suport in the kernel.

The primary API is sfi_table_parse(), where a driver or another part
of the kernel can supply a handler to parse the named table.

sfi.h also includes the currently defined table signatures and table
formats.

From 13e82d023c4c3f13ab1e665cbb917a7ebba8935c Mon Sep 17 00:00:00 2001
From: Feng Tang <feng.tang@intel.com>
Date: Fri, 14 Aug 2009 15:17:53 -0400
Subject: SFI: add capability to parse ACPI tables

Extend SFI to access standard ACPI tables.
(eg. the PCI MCFG) using sfi_acpi_table_parse().

Note that this is _not_ a hybrid ACPI + SFI mode.
The platform boots in either ACPI mode or SFI mode.

SFI runs only with acpi_disabled=1, which can be set
at build-time via CONFIG_ACPI=n, or at boot time by
the failure to find ACPI platform support.

So this extension simply allows SFI-platforms to
re-use existing standard table formats that happen to
be defined to live in ACPI envelopes.

Subject: x86: add arch-specific SFI support

arch/x86/kernel/sfi.c serves the dual-purpose of supporting the
SFI core with arch specific code, as well as a home for the
arch-specific code that uses SFI.

analogous to ACPI, drivers/sfi/Kconfig is pulled in by arch/x86/Kconfig

Add tracepoints which cover the life cycle of a hrtimer. The
tracepoints are integrated with the already existing debug_object
debug points as far as possible.

[ tglx: Fixed comments, made output conistent, easier to read and
  	parse. Fixed output for 32bit archs which do not use the
  	scalar representation of ktime_t. Hand current time to
  	trace_hrtimer_expiry_entry instead of calling get_time()
  	inside of the trace assignment. ]

From 3f0a525ebf4b8ef041a332bbe4a73aee94bb064b Mon Sep 17 00:00:00 2001
From: Xiao Guangrong <xiaoguangrong@cn.fujitsu.com>
Date: Mon, 10 Aug 2009 10:52:30 +0800
Subject: itimers: Add tracepoints for itimer

Add tracepoints for all itimer variants: ITIMER_REAL, ITIMER_VIRTUAL
and ITIMER_PROF.

[ tglx: Fixed comments and made the output more readable, parseable
  	and consistent. Replaced pid_vnr by pid_nr because the hrtimer
  	callback can happen in any namespace ]

Subject: ACPI battery: work around negative s16 battery current on Acer

Acer Aspire 8930G laptops (and possibly others) report the battery current
as a 16-bit signed negative when it is charging.  It also reports it as
0x10000 when the current is 0.  This patch adds a quirk for this which
takes the absolute value of the reported current cast to an s16.  This is
a DSDT bug present in the latest BIOS revision (the EC register is 16 bits
signed and the DSDT attempts to take the 16-bit two's complement of this,
which works for discharge but not charge.  It also breaks zero values
because a 32-bit register is used and the high bits aren't thrown away).

I've enabled this for all Acer systems which report in mA units.  This
should be safe since it won't break compliant systems unless they report a
current above 32A, which is insane.  The patch also detects the valid
32-bit value -1, which indicates unknown status, and does not attempt the
fix in that case (note that this does not conflict with 16-bit -1, which
is 65535 as read normally and gets translated to 1mA).

Subject: ACPI: EC: Merge IRQ and POLL modes

In general, EC transaction should complete in less than 1ms, thus it is possible to merge wait for
1ms in poll mode and 1ms of interrupt transaction timeout.
Still, driver will wait 500ms for EC to complete transaction.

This significantly simplifies driver and makes it immune to problematic EC interrupt
implementations.

It also may lessen kernel start-up time by 500ms.

Subject: md/raid6: move the spare page to a percpu allocation

In preparation for asynchronous handling of raid6 operations move the
spare page to a percpu allocation to allow multiple simultaneous
synchronous raid6 recovery operations.

Make this allocation cpu hotplug aware to maximize allocation
efficiency.

Subject: md/raid5,6: add percpu scribble region for buffer lists

Use percpu memory rather than stack for storing the buffer lists used in
parity calculations.  Include space for dma address conversions and pass
that to async_tx via the async_submit_ctl.scribble pointer.

[ Impact: move memory pressure from stack to heap ]

Subject: async_tx: add sum check flags

Replace the flat zero_sum_result with a collection of flags to contain
the P (xor) zero-sum result, and the soon to be utilized Q (raid6 reed
solomon syndrome) zero-sum result.  Use the SUM_CHECK_ namespace instead
of DMA_ since these flags will be used on non-dma-zero-sum enabled
platforms.

Subject: async_tx: remove walk of tx->parent chain in dma_wait_for_async_tx

We currently walk the parent chain when waiting for a given tx to
complete however this walk may race with the driver cleanup routine.
The routines in async_raid6_recov.c may fall back to the synchronous
path at any point so we need to be prepared to call async_tx_quiesce()
(which calls  dma_wait_for_async_tx).  To remove the ->parent walk we
guarantee that every time a dependency is attached ->issue_pending() is
invoked, then we can simply poll the initial descriptor until
completion.

This also allows for a lighter weight 'issue pending' implementation as
there is no longer a requirement to iterate through all the channels'
->issue_pending() routines as long as operations have been submitted in
an ordered chain.  async_tx_issue_pending() is added for this case.

Subject: async_tx: add support for asynchronous GF multiplication

[ Based on an original patch by Yuri Tikhonov ]

This adds support for doing asynchronous GF multiplication by adding
two additional functions to the async_tx API:

 async_gen_syndrome() does simultaneous XOR and Galois field
    multiplication of sources.

 async_syndrome_val() validates the given source buffers against known P
    and Q values.

When a request is made to run async_pq against more than the hardware
maximum number of supported sources we need to reuse the previous
generated P and Q values as sources into the next operation.  Care must
be taken to remove Q from P' and P from Q'.  For example to perform a 5
source pq op with hardware that only supports 4 sources at a time the
following approach is taken:

p, q = PQ(src0, src1, src2, src3, COEF({01}, {02}, {04}, {08}))
p', q' = PQ(p, q, q, src4, COEF({00}, {01}, {00}, {10}))

p' = p + q + q + src4 = p + src4
q' = {00}*p + {01}*q + {00}*q + {10}*src4 = q + {10}*src4

Note: 4 is the minimum acceptable maxpq otherwise we punt to
synchronous-software path.

The DMA_PREP_CONTINUE flag indicates to the driver to reuse p and q as
sources (in the above manner) and fill the remaining slots up to maxpq
with the new sources/coefficients.

Note1: Some devices have native support for P+Q continuation and can skip
this extra work.  Devices with this capability can advertise it with
dma_set_maxpq.  It is up to each driver how to handle the
DMA_PREP_CONTINUE flag.

Note2: The api supports disabling the generation of P when generating Q,
this is ignored by the synchronous path but is implemented by some dma
devices to save unnecessary writes.  In this case the continuation
algorithm is simplified to only reuse Q as a source.

Subject: async_tx: add support for asynchronous RAID6 recovery operations

 async_raid6_2data_recov() recovers two data disk failures

 async_raid6_datap_recov() recovers a data disk and the P disk

These routines are a port of the synchronous versions found in
drivers/md/raid6recov.c.  The primary difference is breaking out the xor
operations into separate calls to async_xor.  Two helper routines are
introduced to perform scalar multiplication where needed.
async_sum_product() multiplies two sources by scalar coefficients and
then sums (xor) the result.  async_mult() simply multiplies a single
source by a scalar.

This implemention also includes, in contrast to the original
synchronous-only code, special case handling for the 4-disk and 5-disk
array cases.  In these situations the default N-disk algorithm will
present 0-source or 1-source operations to dma devices.  To cover for
dma devices where the minimum source count is 2 we implement 4-disk and
5-disk handling in the recovery code.

[ Impact: asynchronous raid6 recovery routines for 2data and datap cases ]

Subject: async_tx: raid6 recovery self test

Port drivers/md/raid6test/test.c to use the async raid6 recovery
routines.  This is meant as a unit test for raid6 acceleration drivers.  In
addition to the 16-drive test case this implements tests for the 4-disk and
5-disk special cases (dma devices can not generically handle less than 2
sources), and adds a test for the D+Q case.

Subject: iop-adma: fix lockdep false positive

lockdep correctly identifies a potential recursive locking case for
iop_chan->lock, but in the dependency submission case we expect that the same
class will be acquired for both the parent dependency and the child channel.

Date: Fri, 28 Aug 2009 14:32:04 -0700
Subject: iop-adma: P+Q support for iop13xx adma engines

iop33x support is not included because that engine is a bit more awkward
to handle in that it can either be in xor mode or pq mode.  The
dmaengine/async_tx layers currently only comprehend static capabilities.

Note iop13xx does not support hardware PQ continuation so the driver
must handle the DMA_PREP_CONTINUE flag for operations across > 16
sources. From the comment for dma_maxpq:

/* When an engine does not support native continuation we need 3 extra
 * source slots to reuse P and Q with the following coefficients:
 * 1/ {00} * P : remove P from Q', but use it as a source for P'
 * 2/ {01} * Q : use Q to continue Q' calculation
 * 3/ {00} * Q : subtract Q from P' to cancel (2)
 */

From f6dbf651615900646fe0ba1ef5ce1027e5b4748d Mon Sep 17 00:00:00 2001
From: Dan Williams <dan.j.williams@intel.com>
Date: Sat, 29 Aug 2009 19:12:40 -0700
Subject: iop-adma: P+Q self test

Even though the intent is to extend dmatest with P+Q tests there is
still value in having an always-on sanity check to prevent an
unintentionally broken driver from registering.

This depends on raid6_pq.ko for verification, the side effect being that
PQ capable channels will fail to register when raid6 is disabled.

Subject: md/raid5: factor out mark_uptodate from ops_complete_compute5

ops_complete_compute5 can be reused in the raid6 path if it is updated to
generically handle a second target.

Subject: md/raid6: asynchronous raid6 operations

[ Based on an original patch by Yuri Tikhonov ]

The raid_run_ops routine uses the asynchronous offload api and
the stripe_operations member of a stripe_head to carry out xor+pq+copy
operations asynchronously, outside the lock.

The operations performed by RAID-6 are the same as in the RAID-5 case
except for no support of STRIPE_OP_PREXOR operations. All the others
are supported:
STRIPE_OP_BIOFILL
 - copy data into request buffers to satisfy a read request
STRIPE_OP_COMPUTE_BLK
 - generate missing blocks (1 or 2) in the cache from the other blocks
STRIPE_OP_BIODRAIN
 - copy data out of request buffers to satisfy a write request
STRIPE_OP_RECONSTRUCT
 - recalculate parity for new data that has entered the cache
STRIPE_OP_CHECK
 - verify that the parity is correct

The flow is the same as in the RAID-5 case, and reuses some routines, namely:
1/ ops_complete_postxor (renamed to ops_complete_reconstruct)
2/ ops_complete_compute (updated to set up to 2 targets uptodate)
3/ ops_run_check (renamed to ops_run_check_p for xor parity checks)

Subject: md/raid6: asynchronous handle_stripe_dirtying6

In the synchronous implementation of stripe dirtying we processed a
degraded stripe with one call to handle_stripe_dirtying6().  I.e.
compute the missing blocks from the other drives, then copy in the new
data and reconstruct the parities.

In the asynchronous case we do not perform stripe operations directly.
Instead, operations are scheduled with flags to be later serviced by
raid_run_ops.  So, for the degraded case the final reconstruction step
can only be carried out after all blocks have been brought up to date by
being read, or computed.  Like the raid5 case schedule_reconstruction()
sets STRIPE_OP_RECONSTRUCT to request a parity generation pass and
through operation chaining can handle compute and reconstruct in a
single raid_run_ops pass.

Subject: md/raid6: asynchronous handle_parity_check6

[ Based on an original patch by Yuri Tikhonov ]

Implement the state machine for handling the RAID-6 parities check and
repair functionality.  Note that the raid6 case does not need to check
for new failures, like raid5, as it will always writeback the correct
disks.  The raid5 case can be updated to check zero_sum_result to avoid
getting confused by new failures rather than retrying the entire check
operation.

Subject: md/raid6: asynchronous handle_stripe6

1/ Use STRIPE_OP_BIOFILL to offload completion of read requests to
   raid_run_ops
2/ Implement a handler for sh->reconstruct_state similar to the raid5 case
   (adds handling of Q parity)
3/ Prevent handle_parity_checks6 from running concurrently with 'compute'
   operations
4/ Hook up raid_run_ops

Subject: md/raid456: distribute raid processing over multiple cores

Now that the resources to handle stripe_head operations are allocated
percpu it is possible for raid5d to distribute stripe handling over
multiple cores.  This conversion also adds a call to cond_resched() in
the non-multicore case to prevent one core from getting monopolized for
raid operations.

Subject: pci/dmar: correct off-by-one error in dmar_fault()

DMAR faults are recorded into a ring of "fault recording registers".
fault_index is a 0-based index into the ring. The code allows the
0-based fault_index to be equal to the total number of fault registers
available from the cap_num_fault_regs() macro, which causes access
beyond the last available register.

From e67aae79f93d9584aaa24d2a2c76383e9d588f98 Mon Sep 17 00:00:00 2001
From: Maarten Maathuis <madman2003@gmail.com>
Date: Thu, 27 Aug 2009 10:18:29 +0200
Subject: drm/crtc_helper: replace modeset fail path with something simpler

- The previous system was not very transparent, nor flexible.
- This is needed to be able to fix a few bugs in the mechanism.

Subject: radeon: Use request_firmware()

Loosely based on a patch by
Jaswinder Singh Rajput <jaswinderlinux@gmail.com>.

KMS support by Dave Airlie <airlied@redhat.com>.

For Radeon 100- to 500-series, firmware blobs look like:
    struct {
        __be32 datah;
        __be32 datal;
    } cp_ucode[256];

For Radeon 600-series, there are two separate firmware blobs:
    __be32 me_ucode[PM4_UCODE_SIZE * 3];
    __be32 pfp_ucode[PFP_UCODE_SIZE];

For Radeon 700-series, likewise:
    __be32 me_ucode[R700_PM4_UCODE_SIZE];
    __be32 pfp_ucode[R700_PFP_UCODE_SIZE];

From 7dc482dfeeeefcfd000d4271c4626937406756d7 Mon Sep 17 00:00:00 2001
From: Ben Hutchings <ben@decadent.org.uk>

Subject: drm/r128: Add test for initialisation to all ioctls that require it

Almost all r128's private ioctls require that the CCE state has
already been initialised.  However, most do not test that this has
been done, and will proceed to dereference a null pointer.  This may
result in a security vulnerability, since some ioctls are
unprivileged.

This adds a macro for the common initialisation test and changes all
ioctl implementations that require prior initialisation to use that
macro.

Also, r128_do_init_cce() does not test that the CCE state has not
been initialised already.  Repeated initialisation may lead to a crash
or resource leak.  This adds that test.

Subject: drm/kms: move driver specific fb common code to helper functions (v2)

Initially I always meant this code to be shared, but things
ran away from me before I got to it.

This refactors the i915 and radeon kms fbdev interaction layers
out into generic helpers + driver specific pieces.

It moves all the panic/sysrq enhancements to the core file,
and stores a linked list of kernel fbs. This could possibly be
improved to only store the fb which has fbcon on it for panics
etc.

radeon retains some specific codes used for a big endian
workaround.

changes:
fix oops in v1
fix freeing path for crtc_info

From 882f0219518196a94cd2772004e87b178467139a Mon Sep 17 00:00:00 2001
From: Zhao Yakui <yakui.zhao@intel.com>

Subject: drm/kms: Parse the detailed time info in CEA-EDID

Sometimes we can obtain the EDID with multiple blocks from the display device.
For example: HDMI monitor.
When the CEA-EDID block is detected, we should also parse the detailed timing
info from it. Otherwise we will lose some modes for the display device.

The first step is check whether the CEA EDID block is found. If it exists,
it will skip the CEA-data block and parse the detailed timing info.

Similar to commit b6adc195 (PCI hotplug: acpiphp wants a 64-bit
_SUN), pci_slot.ko reads and creates sysfs directories based on
the _SUN method.

Certain HP platforms return 64 bits in _SUN. This change to
pci_slot.ko allows us to see the correct sysfs directories.

Subject: ACPI: fix NULL bug for HID/UID string

acpi_device->pnp.hardware_id and unique_id are now allocated pointers,
replacing the previous arrays.  acpi_device_install_notify_handler()
oopsed on the NULL hid when probing the video device, and perhaps other
uses are vulnerable too.  So initialize those pointers to empty strings
when there is no hid or uid.  Also, free hardware_id and unique_id when
when acpi_device is going to be freed.

Subject: drm/mm: add ability to dump mm lists via debugfs

This adds code to the drm_mm to talk to debugfs, and adds
support to radeon to add the VRAM and GTT mm lists to debugfs.

I tested with spinlock debugging and it doesn't give out.

Subject: drm/kms: add explicit encoder disable function and detach harder.

For shared tv-out and VGA encoders, we really need to know if
the encoder is just being switched off temporarily in blanking
or if we are really disabling it hard.

Also we need to try harder to disconnect encoders from unused
connectors so we can share more efficently.

(shared encoders stuff is coming in radeon tv-out support)

Subject: nfsd41: bound forechannel drc size by memory usage

By using the requested ca_maxresponsesize_cached * ca_maxresponses to bound
a forechannel drc request size, clients can tailor a session to usage.

For example, an I/O session (READ/WRITE only) can have a much smaller
ca_maxresponsesize_cached (for only WRITE compound responses) and a lot larger

Subject: nfsd41: use session maxreqs for sequence target and highest slotid

This fixes a bug in the sequence operation reply.

The sequence operation returns the highest slotid it will accept in the future
in sr_highest_slotid, and the highest slotid it prefers the client to use.
Since we do not re-negotiate the session slot table yet, these should both
always be set to the session ca_maxrequests.

Subject: nfsd41: replace nfserr_resource in pure nfs41 responses

nfserr_resource is not a legal error for NFSv4.1. Replace it with
nfserr_serverfault for EXCHANGE_ID and CREATE_SESSION processing.

We will also need to map nfserr_resource to other errors in routines shared
by NFSv4.0 and NFSv4.1

Subject: nfsd41: replace page based DRC with buffer based DRC

Use NFSD_SLOT_CACHE_SIZE size buffers for sessions DRC instead of holding nfsd
pages in cache.

Connectathon testing has shown that 1024 bytes for encoded compound operation
responses past the sequence operation is sufficient, 512 bytes is a little too
small. Set NFSD_SLOT_CACHE_SIZE to 1024.

Allocate memory for the session DRC in the CREATE_SESSION operation
to guarantee that the memory resource is available for caching responses.
Allocate each slot individually in preparation for slot table size negotiation.

Remove struct nfsd4_cache_entry and helper functions for the old page-based
DRC.

The iov_len calculation in nfs4svc_encode_compoundres is now always
correct.  Replay is now done in nfsd4_sequence under the state lock, so
the session ref count is only bumped on non-replay. Clean up the
nfs4svc_encode_compoundres session logic.

The nfsd4_compound_state statp pointer is also not used.
Remove nfsd4_set_statp().

Move useful nfsd4_cache_entry fields into nfsd4_slot.

Subject: NFSd: Fix filehandle leak in exp_pseudoroot() and nfsd4_path()

nfsd4_path() allocates a temporary filehandle and then fails to free it
before the function exits, leaking reference counts to the dentry and
export that it refers to.

Also, nfsd4_lookupp() puts the result of exp_pseudoroot() in a temporary
filehandle which it releases on success of exp_pseudoroot() but not on
failure; fix exp_pseudoroot to ensure that on failure it releases the
filehandle before returning.

Subject: mtd: physmap_of: fix incorrect check

This patch fixes a spelling error that has resulted from copy and
pasting. The location of the error was found using a semantic patch
but the semantic patch was not trying to find these errors. After
looking things over it seemed logical that this change was needed.

The patch also makes sure mtd_list is not being freed if it has not
been allocated

Subject: mtd: pmcmsp-flash: fix error paths in init_msp_flash

Cleanin up after errors in init_msp_flash().

Also cleanup_msp_flash() attempts to determine the size of
msp_flash with `sizeof(msp_flash) / sizeof(struct mtd_info **)'
This will not work since msp_flash is not an array.

Subject: nfsd4: filehandle leak or error exit from fh_compose()

A number of callers (nfsd4_encode_fattr(), at least) don't bother to
release the filehandle returned to fh_compose() if fh_compose() returns
an error.  So, modify fh_compose() to release the filehandle before
returning an error.

Subject: ds2760_battery: Fix integer overflow for time_to_empty_now

On the device we're currently developing, battery sizes of ~2.8Ah and
current flow of ~600mA are typical.

With that values, the life_sec computation overflows due to the
multiplication by 3600.

Subject: power_supply: Add driver for the PMU on WM831x PMICs

The WM831x PMICs provide power path management from three sources:
a wall supply, USB and a battery with integrated charger. They also
provide an additional backup supply with integrated for maintaining
always on functionality such as the RTC and monitoring of power
switches.

After some initial configuration at startup the device operates
autonomously, the driver simply provides reporting of the current
state.

Subject: nfsd: clean up readdirplus encoding

Make the return from compose_entry_fh() zero or an error, even though
the returned error isn't used, just to make the meaning of the return
immediately obvious.

Move some repeated code out of main function into helper.

Subject: drm/i915: Add i915 register dumping debugfs file

Add a debugfs file to dump the entire register range. Here we
assume that reading write-only/reserved registers won't make the chip
angry. Seems to hold true, thankfully.

Subject: drm/i915: select TV format according to connector type

For integrated TV there are 3 connector types: S-VIDEO, Composite and
Component(YprPb). Those tv formats whose component flag is true should
be assigned to Component connector, others are for S-VIDEO and Composite.
The patch intends to find appropriate tv format for each connector.
In such case it will return the correct modeline to user space. Otherwise
it will return the incorrect modeline when S-video/composite is connected.

Subject: drm/i915: Enable PAL and SECAM format and add the propery for SDVO-TV

Currently SDVO TV only support NTSC-M format. In this patch
we introduce PAL and SECAM formats available and create seting-format
property at init time. When user dynamically chose preferred
format by xrandr command, it will refine all modelines
provided by SDVO device, then instruct SDVO device to execute.
At the same time the property is added for SDVO-TV so that the SDVO-TV mode can be changed
by using xrandr.

Subject: drm/i915: Support IGD EOS

In the event that any one of the DAC analog outputs (R,G,B) were driven
at full-scale (white video) or some analog level close to full-scale
voltage, and if the video cable were then disconnected, the analog video
voltage level would exceed the maximum electrical overstress limit of the
native (thin-oxide) transistors thus causing a long-term reliability concern.
The electrical overstress condition occurs in this particular case.

This patch address the IGD EOS (electrical overstress condition) issue.
When the EOS interrupt occurs, OS should disable DAC and then disable EOS,
then the normal hotplug operation follows.

TODO: it appears the normal unplug interrupt is missed as reported by Li Peng,
need more checks here.

Subject: drm/i915: add dynamic clock frequency control

There are several sources of unnecessary power consumption on Intel
graphics systems. The first is the LVDS clock. TFTs don't suffer from
persistence issues like CRTs, and so we can reduce the LVDS refresh rate
when the screen is idle. It will be automatically upclocked when
userspace triggers graphical activity. Beyond that, we can enable memory
self refresh. This allows the memory to go into a lower power state when
the graphics are idle. Finally, we can drop some clocks on the gpu
itself. All of these things can be reenabled between frames when GPU
activity is triggered, and so there should be no user visible graphical
changes.

Subject: drm/i915: fix tiling on IGDNG

It seems that on IGDNG the same swizzling setup always applys.
And front buffer tiling needs to set address swizzle in display
arb control too.

Fix plane tricle feed setting in v1 which should be disable bit,
and always setup address swizzle to let hardware care for buffer
tiling in all cases.

Subject: drm/I915: Use the CRT DDC to get the EDID for DVI-connector on Mac

mac Mini's have a single DDC line on the DVI connector, shared between the
analog link and the digital link. So, if DDC isn't detected on GPIOE (the
usual SDVO DDC link), try GPIOA (the usual VGA DDC link) when there isn't a
VGA monitor connected.

Subject: ocfs2: Make the ocfs2_caching_info structure self-contained.

We want to use the ocfs2_caching_info structure in places that are not
inodes.  To do that, it can no longer rely on referencing the inode
directly.

This patch moves the flags to ocfs2_caching_info->ci_flags, stores
pointers to the parent's locks on the ocfs2_caching_info, and renames
the constants and flags to reflect its independant state.

Subject: ocfs2: Change metadata caching locks to an operations structure.

We don't really want to cart around too many new fields on the
ocfs2_caching_info structure.  So let's wrap all our access of the
parent object in a set of operations.  One pointer on caching_info, and
more flexibility to boot.

From 8cb471e8f82506937fe5e2e9fb0bf90f6b1f1170 Mon Sep 17 00:00:00 2001
From: Joel Becker <joel.becker@oracle.com>
Date: Tue, 10 Feb 2009 20:00:41 -0800
Subject: ocfs2: Take the inode out of the metadata read/write paths.

We are really passing the inode into the ocfs2_read/write_blocks()
functions to get at the metadata cache.  This commit passes the cache
directly into the metadata block functions, divorcing them from the
inode.

Subject: ocfs2: move ip_last_trans to struct ocfs2_caching_info

We have the read side of metadata caching isolated to struct
ocfs2_caching_info, now we need the write side.  This means the journal
functions.  The journal only does a couple of things with struct inode.

This change moves the ip_last_trans field onto struct
ocfs2_caching_info as ci_last_trans.  This field tells the journal
whether a pending journal flush is required.

Subject: ocfs2: move ip_created_trans to struct ocfs2_caching_info

Similar ip_last_trans, ip_created_trans tracks the creation of a journal
managed inode.  This specifically tracks what transaction created the
inode.  This is so the code can know if the inode has ever been written
to disk.

This behavior is desirable for any journal managed object.  We move it
to struct ocfs2_caching_info as ci_created_trans so that any object
using ocfs2_caching_info can rely on this behavior.

Subject: ocfs2: Pass struct ocfs2_caching_info to the journal functions.

The next step in divorcing metadata I/O management from struct inode is
to pass struct ocfs2_caching_info to the journal functions.  Thus the
journal locks a metadata cache with the cache io_lock function.  It also
can compare ci_last_trans and ci_created_trans directly.

This is a large patch because of all the places we change
ocfs2_journal_access..(handle, inode, ...) to
ocfs2_journal_access..(handle, INODE_CACHE(inode), ...).

Subject: ocfs2: Store the ocfs2_caching_info on ocfs2_extent_tree.

What do we cache?  Metadata blocks.  What are most of our non-inode metadata
blocks?  Extent blocks for our btrees.  struct ocfs2_extent_tree is the
main structure for managing those.  So let's store the associated
ocfs2_caching_info there.

This means that ocfs2_et_root_journal_access() doesn't need struct inode
anymore, and any place that has an et can refer to et->et_ci instead of
INODE_CACHE(inode).

Subject: ocfs2: Pass ocfs2_caching_info to ocfs2_read_extent_block().

extent blocks belong to btrees on more than just inodes, so we want to
pass the ocfs2_caching_info structure directly to
ocfs2_read_extent_block().  A number of places in alloc.c can now drop
struct inode from their argument list.

From facdb77f54f09a33baf6b649496f5dd1d7922a7e Mon Sep 17 00:00:00 2001
From: Joel Becker <joel.becker@oracle.com>
Date: Thu, 12 Feb 2009 18:08:48 -0800
Subject: ocfs2: ocfs2_find_path() only needs the caching info

ocfs2_find_path and ocfs2_find_leaf() walk our btrees, reading extent
blocks.  They need struct ocfs2_caching_info for that, but not struct
inode.

Subject: ocfs2: ocfs2_create_new_meta_bhs() doesn't need struct inode.

Pass struct ocfs2_extent_tree into ocfs2_create_new_meta_bhs().  It no
longer needs struct inode or ocfs2_super.

Subject: ocfs2: Drop struct inode from ocfs2_extent_tree_operations.

We can get to the inode from the caching information.  Other parent
types don't need it.

Subject: ocfs2: ocfs2_rotate_tree_left() no longer needs struct inode.

It already gets ocfs2_extent_tree, so we can just use that.  This chains
to the same modification for ocfs2_remove_rightmost_path() and
ocfs2_rotate_rightmost_leaf_left().

Subject: ocfs2: ocfs2_try_to_merge_extent() doesn't need struct inode.

It's not using it, so remove it from the parameter list.

Subject: ocfs2: ocfs2_grow_branch() and ocfs2_append_rec_to_path() lose struct
 inode.

ocfs2_grow_branch() not really using it other than to pass it to the
subfunctions ocfs2_shift_tree_depth(), ocfs2_find_branch_target(), and
ocfs2_add_branch().  The first two weren't it either, so they drop the
argument.  ocfs2_add_branch() only passed it to
ocfs2_adjust_rightmost_branch(), which drops the inode argument and uses
the ocfs2_extent_tree as well.

ocfs2_append_rec_to_path() can be take an ocfs2_extent_tree instead of
the inode.  The function ocfs2_adjust_rightmost_records() goes along for
the ride.

Subject: ocfs2: Make truncating the extent map an extent_tree_operation.

ocfs2_remove_extent() wants to truncate the extent map if it's
truncating an inode data extent.  But since many btrees can call that
function, let's make it an op on ocfs2_extent_tree.  Other tree types
can leave it empty.

Subject: ocfs2: Make extent map insertion an extent_tree_operation.

ocfs2_insert_extent() wants to insert a record into the extent map if
it's an inode data extent.  But since many btrees can call that
function, let's make it an op on ocfs2_extent_tree.  Other tree types
can leave it empty.

Subject: ocfs2: __ocfs2_mark_extent_written() doesn't need struct inode.

We only allow unwritten extents on data, so the toplevel
ocfs2_mark_extent_written() can use an inode all it wants.  But the
subfunction isn't even using the inode argument.

Subject: drm/i915: Pad ringbuffer with NOOPs before wrapping
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

According to the docs, the ringbuffer is not allowed to wrap in the middle
of an instruction.

G45 PRM, Vol 1b, p101:
  While the “free space” wrap may allow commands to be wrapped around the
  end of the Ring Buffer, the wrap should only occur between commands.
  Padding (with NOP) may be required to follow this restriction.

Do as commanded.

[Having seen bug reports where there is evidence of split commands, but
apparently the GPU has continued on merrily before a bizarre and untimely
death, this may or may not fix a few random hangs.]

From aa9eaa1f0962152d0bde821149d82fe7b70a6f92 Mon Sep 17 00:00:00 2001
From: Zhao Yakui <yakui.zhao@intel.com>

Subject: drm/kms: Add the default mode table

When we add a standard timing mode in UMS, we will first check whether it can
be found in default mode table. If it can't be found, then we will use cvt/gtf
to add the standard timing mode.
Add the default mode table so that we can check whether the given mode
can be found in the default mode table as what we have done in UMS mode.

If the status of one output device is connected but there is no EDID, it will
have no correct mode. In such case we can add some default modes for it. Of
course we only add the modes in the default modes list that visible part is not
greater than 1024x768.

The default mode is autogenerated from the DMT spec. And it is copied from
xserver/hw/xfree86/modes/xf86EdidModes.c. But the mode with reduced blank
feature is removed.

Subject: drm/kms: try to find the std mode in DMT table

When we need to add the standard timing mode, we will firstly check whether it
can be found in DMT table by comparing the hdisplay/vdisplay/vfresh_rate.
If it can't be found, then we will use the cvt/gtf to add the required mode.
If it can be found, it will be returned.

At the same time the function of drm_mode_vrefresh is also fixed. It will
return the result of actual refresh_rate plus 0.5.
For example:
When the calculated value is 84.9, then the fresh_rate is 85.
When the calculated value is 70.02, then the fresh_rate is 70.

Subject: drm/kms: remove old std mode fallback code.

The new code adds modes in the helper, which makes more sense
I disliked the non-driver code adding modes.

Subject: backlight: Add WM831x backlight driver

The WM831x series of PMICs provide DC-DC boost convertors and current
sinks which can be used together to drive LEDs for use as backlights.
Expose this functionality via the backlight API.

Since when used in this configuration the current sink and boost
convertor are very tightly coupled with a multi-stage startup for
the current sink which overlaps with the boost convertor startup
this driver bypasses the regulator API. Machine inititialisation
is responsible for ensuring that the regulators are not accessed
via both APIs.

Subject: leds: Add WM831x status LED driver

The WM831x devices feature two software controlled status LEDs with
hardware assisted blinking.

The device can also autonomously control the LEDs based on a selection
of sources.  This can be configured at boot time using either platform
data or the chip OTP.  A sysfs file in the style of that for triggers
allowing the control source to be configured at run time.  Triggers
can't be used here since they can't depend on the implementation details
of a specific LED type.

MIME-Version: 1.0

A pointer to hp680bl_probe is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded.  Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.

Subject: backlight: spi driver for LMS283GF05 LCD

ADd support for the SPI part of LMS283GF05 LCD.  The LCD uses SPI for
initialization and powerdown sequences.  No further defails are specified
in the datasheet about the initialization/powerdown sequence, just the
magic numbers that have to be sent over SPI bus.  This LCD can be found in
the Aeronix Zipit Z2 handheld.

From 551ebd837c75fc75df81811a18b7136c39cab487 Mon Sep 17 00:00:00 2001
From: Dave Airlie <airlied@redhat.com>
Date: Tue, 1 Sep 2009 15:25:57 +1000
Subject: drm/radeon/kms: add rn50/r100/r200 CS tracker.

This adds the command stream checker for the RN50, R100 and R200 cards.

It stops any access to 3D registers on RN50, and does checks
on buffer sizes on the r100/r200 cards. It also fixes some texture
sizing checks on r300.

Subject: drm/radeon/kms: add r600 KMS support

This adds the r600 KMS + CS support to the Linux kernel.

The r600 TTM support is quite basic and still needs more
work esp around using interrupts, but the polled fencing
should work okay for now.

Also currently TTM is using memcpy to do VRAM moves,
the code is here to use a 3D blit to do this, but
isn't fully debugged yet.

Subject: drm/i915: get the bridge device once.

The driver gets the bridge device in a number of places, upcoming
vga arb code paths need the bridge device, however they need it in
under a lock, and the pci lookup can allocate memory. So clean
this code up before then and get the bridge once for the driver lifetime.

Subject: drm: prune modes when output is disconnected.

When an output was disconnected, its mode list would remain.  If you later
plugged into a sink with no EDID (projector, etc), you'd inherit the mode
list from the old sink, which is not what you want.

Subject: ioat: move definitions to dma.h

Some of these defines may be useful outside of dma.c and the header is
private so there are no namespace pollution concerns.

Subject: ioat: convert ioat_probe to pcim/devm

The driver currently duplicates much of what these routines offer, so
just use the common code.  For example ->irq_mode tracks what interrupt
mode was initialized, which duplicates the ->msix_enabled and
->msi_enabled handling in pcim_release.

This also adds a check to the return value of dma_async_device_register,
which can fail.

Subject: ioat: cleanup some long deref chains and 80 column collisions

* reduce device->common. to dma-> in ioat_dma_{probe,remove,selftest}
* ioat_lookup_chan_by_index to ioat_chan_by_index
* multi-line function definitions
* ioat_desc_sw.async_tx to ioat_desc_sw.txd
* desc->txd. to tx-> in cleanup routine

The only .c files that utilize these protected prototypes depend on
CONFIG_INTEL_IOATDMA=y, so there is no value gained in providing empty
prototypes.

Subject: ioat: split ioat_dma_probe into core/version-specific routines

Towards the removal of ioatdma_device.version split the initialization
path into distinct versions.  This conversion:
1/ moves version specific probe code to version specific routines
2/ removes the need for ioat_device
3/ turns off the ioat1 msi quirk if the device is reinitialized for intx

Subject: ioat: fix type mismatch for ->dmacount

->dmacount tracks the sequence number of active descriptors.  It is
written to the DMACOUNT register to update the channel's view of pending
descriptors in the chain.  The register is 16-bits so ->dmacount should
be unsigned and 16-bit as well.  Also modify ->desccount to maintain
alignment.

This was never a problem in practice because we never compared dmacount
values, but this is a bug waiting to happen.

Subject: ioat1: move descriptor allocation from submit to prep

The async_tx api assumes that after a successful ->prep a subsequent
->submit will not fail due to a lack of resources.

This also fixes a bug in the allocation failure case.  Previously the
descriptors allocated prior to the allocation failure would not be
returned to the free list.

Subject: ioat: fix self test interrupts

If a callback is to be attached to a descriptor the channel needs to
know at ->prep time so it can set the interrupt enable bit.  This is in
preparation for moving descriptor ioat2 descriptor preparation from
->submit to ->prep.

Subject: ioat: prepare the code for ioat[12]_dma_chan split

Prepare the code for the conversion of the ioat2 linked-list-ring into a
native ring buffer.  After this conversion ioat2 channels will share
less of the ioat1 infrastructure, but there will still be places where
sharing is possible.  struct ioat_chan_common is created to house the
channel attributes that will remain common between ioat1 and ioat2
channels.

For every routine that accesses both common and hardware specific fields
the old unified 'ioat_chan' pointer is split into an 'ioat' and  'chan'
pointer.  Where 'chan' references common fields and 'ioat' the
hardware/version specific.

[ Impact: pure structure member movement/variable renames, no logic changes ]

From 5cbafa65b92ee4f5b8ba915cddf94b91f186b989 Mon Sep 17 00:00:00 2001
From: Dan Williams <dan.j.williams@intel.com>
Date: Wed, 26 Aug 2009 13:01:44 -0700
Subject: ioat2,3: convert to a true ring buffer

Replace the current linked list munged into a ring with a native ring
buffer implementation.  The benefit of this approach is reduced overhead
as many parameters can be derived from ring position with simple pointer
comparisons and descriptor allocation/freeing becomes just a
manipulation of head/tail pointers.

It requires a contiguous allocation for the software descriptor
information.

Since this arrangement is significantly different from the ioat1 chain,
move ioat2,3 support into its own file and header.  Common routines are
exported from driver/dma/ioat/dma.[ch].

Subject: ioat1: kill unused unmap parameters

The unified ioat1/ioat2 ioat_dma_unmap() implementation derives the
source and dest addresses from the unmap descriptor.  There is no longer
a need to track this information in struct ioat_desc_sw.

Subject: ioat: cleanup completion status reads

The cleanup path makes an effort to only perform an atomic read of the
64-bit completion address.  However in the 32-bit case it does not
matter if we read the upper-32 and lower-32 non-atomically because the
upper-32 will always be zero.

Subject: ioat: preserve chanctrl bits when re-arming interrupts

The register write in ioat_dma_cleanup_tasklet is unfortunate in two
ways:
1/ It clears the extra 'enable' bits that we set at alloc_chan_resources time
2/ It gives the impression that it disables interrupts when it is in
   fact re-arming interrupts

[ Impact: fix, persist the value of the chanctrl register when re-arming ]

Subject: ioat: switch watchdog and reset handler from workqueue to timer

In order to support dynamic resizing of the descriptor ring or polling
for a descriptor in the presence of a hung channel the reset handler
needs to make progress while in a non-preemptible context.  The current
workqueue implementation precludes polling channel reset completion
under spin_lock().

This conversion also allows us to return to opportunistic cleanup in the
ioat2 case as the timer implementation guarantees at least one cleanup
after every descriptor is submitted.  This means the worst case
completion latency becomes the timer frequency (for exceptional
circumstances), but with the benefit of avoiding busy waiting when the
lock is contended.

From a309218acee8606f7e235da20cc826eb06d9b0f6 Mon Sep 17 00:00:00 2001
From: Dan Williams <dan.j.williams@intel.com>
Date: Tue, 8 Sep 2009 12:02:01 -0700
Subject: ioat2,3: dynamically resize descriptor ring

Increment the allocation order of the descriptor ring every time we run
out of descriptors up to a maximum of allocation order specified by the
module parameter 'ioat_max_alloc_order'.  After each idle period
decrement the allocation order to a minimum order of
'ioat_ring_alloc_order' (i.e. the default ring size, tunable as a module
parameter).

Subject: net_dma: poll for a descriptor after allocation failure

Handle descriptor allocation failures by polling for a descriptor.  The
driver will force forward progress when polled.  In the best case this
polling interval will be the time it takes for one dma memcpy
transaction to complete.  In the worst case, channel hang, we will need
to wait 100ms for the cleanup watchdog to fire (ioatdma driver).

Subject: dmaengine: add fence support

Some engines optimize operation by reading ahead in the descriptor chain
such that descriptor2 may start execution before descriptor1 completes.
If descriptor2 depends on the result from descriptor1 then a fence is
required (on descriptor2) to disable this optimization.  The async_tx
api could implicitly identify dependencies via the 'depend_tx'
parameter, but that would constrain cases where the dependency chain
only specifies a completion order rather than a data dependency.  So,
provide an ASYNC_TX_FENCE to explicitly identify data dependencies.

From 138f4c359d23d2ec38d18bd70dd9613ae515fe93 Mon Sep 17 00:00:00 2001
From: Dan Williams <dan.j.williams@intel.com>
Date: Tue, 8 Sep 2009 17:42:51 -0700
Subject: dmaengine, async_tx: add a "no channel switch" allocator

Channel switching is problematic for some dmaengine drivers as the
architecture precludes separating the ->prep from ->submit.  In these
cases the driver can select ASYNC_TX_DISABLE_CHANNEL_SWITCH to modify
the async_tx allocator to only return channels that support all of the
required asynchronous operations.

For example MD_RAID456=y selects support for asynchronous xor, xor
validate, pq, pq validate, and memcpy.  When
ASYNC_TX_DISABLE_CHANNEL_SWITCH=y any channel with all these
capabilities is marked DMA_ASYNC_TX allowing async_tx_find_channel() to
quickly locate compatible channels with the guarantee that dependency
chains will remain on one channel.  When
ASYNC_TX_DISABLE_CHANNEL_SWITCH=n async_tx_find_channel() may select
channels that lead to operation chains that need to cross channel
boundaries using the async_tx channel switch capability.

Subject: dmaengine, async_tx: support alignment checks

Some engines have transfer size and address alignment restrictions.  Add
a per-operation alignment property to struct dma_device that the async
routines and dmatest can use to check alignment capabilities.

Subject: ioat2+: add fence support

In preparation for adding more operation types to the ioat3 path the
driver needs to honor the DMA_PREP_FENCE flag.  For example the async_tx api
will hand xor->memcpy->xor chains to the driver with the 'fence' flag set on
the first xor and the memcpy operation.  This flag in turn sets the 'fence'
flag in the descriptor control field telling the hardware that future
descriptors in the chain depend on the result of the current descriptor, so
wait for all writes to complete before starting the next operation.

Note that ioat1 does not prefetch the descriptor chain, so does not
require/support fenced operations.

Subject: ioat3: split ioat3 support to its own file, add memset

Up until this point the driver for Intel(R) QuickData Technology
engines, specification versions 2 and 3, were mostly identical save for
a few quirks.  Version 3.2 hardware adds many new capabilities (like
raid offload support) requiring some infrastructure that is not relevant
for v2.  For better code organization of the new funcionality move v3
and v3.2 support to its own file dma_v3.c, and export some routines from
the base files (dma.c and dma_v2.c) that can be reused directly.

The first new capability included in this code reorganization is support
for v3.2 memset operations.

From 5669e31c5a4874f1634bc0ffba268a6e2fa0cdd2 Mon Sep 17 00:00:00 2001
From: Dan Williams <dan.j.williams@intel.com>
Date: Tue, 8 Sep 2009 17:42:56 -0700
Subject: ioat: add 'ioat' sysfs attributes

Export driver attributes for diagnostic purposes:
'ring_size': total number of descriptors available to the engine
'ring_active': number of descriptors in-flight
'capabilities': supported operation types for this channel
'version': Intel(R) QuickData specfication revision

This also allows some chattiness to be removed from the driver startup
as this information is now available via sysfs.

Subject: ioat3: xor support

ioat3.2 adds xor offload support for up to 8 sources.  It can also
perform an xor-zero-sum operation to validate whether all given sources
sum to zero, without writing to a destination.  Xor descriptors differ
from memcpy in that one operation may require multiple descriptors
depending on the number of sources.  When the number of sources exceeds
5 an extended descriptor is needed.  These descriptors need to be
accounted for when updating the DMA_COUNT register.

Subject: ioat3: xor self test

This adds a hardware specific self test to be called from ioat_probe.
In the ioat3 case we will have tests for all the different raid
operations, while ioat1 and ioat2 will continue to just test memcpy.

Subject: ioat3: pq support

ioat3.2 adds support for raid6 syndrome generation (xor sum of galois
field multiplication products) using up to 8 sources.  It can also
perform an pq-zero-sum operation to validate whether the syndrome for a
given set of sources matches a previously computed syndrome.

Subject: ioat3: ioat3.2 pci ids for Jasper Forest

Jasper Forest introduces raid offload support via ioat3.2 support.  When
raid offload is enabled two (out of 8 channels) will report raid5/raid6
offload capabilities.  The remaining channels will only report ioat3.0
capabilities (memcpy).

Subject: ioat3: segregate raid engines

The cleanup routine for the raid cases imposes extra checks for handling
raid descriptors and extended descriptors.  If the channel does not
support raid it can avoid this extra overhead by using the ioat2 cleanup
path.

Subject: dmaengine: kill tx_list

The tx_list attribute of struct dma_async_tx_descriptor is common to
most, but not all dma driver implementations.  None of the upper level
code (dmaengine/async_tx) uses it, so allow drivers to implement it
locally if they need it.  This saves sizeof(struct list_head) bytes for
drivers that do not manage descriptors with a linked list (e.g.: ioatdma
v2,3).

Subject: ioat2,3: cacheline align software descriptor allocations

All the necessary fields for handling an ioat2,3 ring entry can fit into
one cacheline.  Move ->len prior to ->txd in struct ioat_ring_ent, and
move allocation of these entries to a hw-cache-aligned kmem cache to
reduce the number of cachelines dirtied for descriptor management.

Subject: fsldma: split apart external pause and request count features

When using the Freescale DMA controller in external control mode, both the
request count and external pause bits need to be setup correctly. This was
being done with the same function.

The 83xx controller lacks the external pause feature, but has a similar
feature called external start. This feature requires that the request count
bits be setup correctly.

Split the function into two parts, to make it possible to use the external
start feature on the 83xx controller.

Subject: fsldma: Add DMA_SLAVE support

Use the DMA_SLAVE capability of the DMAEngine API to copy/from a
scatterlist into an arbitrary list of hardware address/length pairs.

This allows a single DMA transaction to copy data from several different

This also adds support to enable some controller-specific features such as
external start and external pause for a DMA transaction.

Subject: dmaengine: Move all map_sg/unmap_sg for slave channel to its client

Dan Williams wrote:
... DMA-slave clients request specific channels and know the hardware
details at a low level, so it should not be too high an expectation to
push dma mapping responsibility to the client.

Also this patch includes DMA_COMPL_{SRC,DEST}_UNMAP_SINGLE support for
dw_dmac driver.

Subject: async_tx: remove HIGHMEM64G restriction

This restriction prevented ASYNC_TX_DMA from being enabled on platform
configurations where DMA address conversion could not be performed in
place on the stack.  Since commit 04ce9ab3 ("async_xor: permit callers
to pass in a 'dma/page scribble' region") the async_tx api now either
uses a caller provided 'scribble' buffer, or performs the conversion in
place when sizeof(dma_addr_t) <= sizeof(struct page *).

Subject: ACPICA: Fix memory leak for ill-formed Package objects

Fixes a possible memory leak in the interpreter for package
objects if the package initializer list is longer than the
defined size of the package. This apparently can only happen
if the BIOS changes the package size on the fly (seen in a _PSS
object), as both iASL and the other compiler do not allow this.
The interpreter will truncate the package to the defined size
(and issue an error message), but can leave the extra objects
undeleted if they have been pre-created during the argument
processing (such is the case if the package consists of a number
of sub-packages as in the _PSS.) ACPICA BZ 805.

Subject: drm/i915: Zap mmaps of objects before unbinding them from the GTT.

Otherwise, some other userland writing into its buffer may race to land
writes either after the CPU thinks it's got a coherent view, or after its
GTT entries have been redirected to point at the scratch page.  Either
result is unpleasant.

Subject: drm/radeon/kms: wait for cp idle before stopping it.

If we stop CP and that it's still processing thing GPU hang might
happen, this patch wait for CP idle (the wait can timeout) so we
can avoid shutting down CP at bad time. This is especialy usefull
when reseting the GPU as it seems GPU reset fails to properly reset
CP when the CP wasn't stop after being idle.

Subject: drm/radeon/kms: call r100_cp_disable rather than duplicating code.

r100_cp_fini was duplicating code of r100_cp_disable, call r100_cp_disable
instead.

Subject: drm/radeon/kms: Don't try to process irq when we are unloading

If module is being unloaded we should not try to handle irq especialy
we should not call into drm helper or we could hard hang the computer
free_irq will call the irq handler to make sure we behave properly.

Subject: drm/radeon/kms/r600: fix blit support

select the correct max number of bytes per blit based
on whether the size is multiple of 4 bytes.  This
determines whether we can use 8 or 32 bit pixels for
the blit.

Subject: UBIFS: do not print scary error messages needlessly

At the moment UBIFS print large and scary error messages and
flash dumps in case of nearly any corruption, even if it is
a recoverable corruption. For example, if the master node is
corrupted, ubifs_scan() prints error dumps, then UBIFS recovers
just fine and goes on.

This patch makes UBIFS print scary error messages only in
real cases, which are not recoverable. It adds 'quiet' argument
to the 'ubifs_scan()' function, so the caller may ask 'ubi_scan()'
not to print error messages if the caller is able to do recovery.

Subject: UBIFS: check ubifs_scan error codes better

The 'ubifs_scan()' function returns -EUCLEAN if something is corrupted
and recovery is needed, otherwise it returns other error codes. However,
in few places UBIFS does not check the error codes and runs recovery.
This patch changes this behavior and makes UBIFS start recovery only
on -EUCLEAN errors.

Subject: [ARM] pxa: add MFP_PULL_FLOAT

There is currently an uncovered case for MFP configuration on PXAs which
is selected by setting the PULL_SEL bit but none of the PULL{UP,DOWN}_EN
bits. This case is needed to explicitly let pins float, even if the
selected alternate function would default to a configuration with a pull
resistor enabled.

Subject: [ARM] pxa/dma: add debugfs entries

Add some debug information for PXA DMA :
 - descriptors queued
 - channels state
 - global state

Subject: [ARM] pxamci: add simple gpio controls

The MMC block needs 3 external datas to work :
 - is the MMC card put in "read-only mode" ?
 - is a MMC card inserted or removed ?
 - enable power towards the MMC card

Several platforms provide these controls through
gpios. Expand the platform_data to request and use these
gpios is set up by board code.

Subject: [ARM] pxa: factor pxamci gpio handling

Several boards use always the same pattern with pxamci :
request gpio, request irq for that gpio to detect MMC card
insertion, request gpio for read-only mode detection, etc
...

Now that pxamci provides platform_data to describe simple
gpio management of the MMC external controls, use it.

Subject: [ARM] pxa/colibri: add UART MFP configuration for the PXA320 module

This patch configures the MFP pads for UART1, UART2, UART3 for the
Toradex Colibri PXA320 module. Previously they were just not
configured resulting in just the first UART working because it was the
only one that was configured by the bootloader (Toradex EBOOT in our
case).

This patch is against vanilla 2.6.30 and has been tested with the
Toradex Orchid carrier board (all three UARTs were functional).

Subject: [ARM] pxa/palm: fix possibly uninitialized variable in PalmTC-pcmcia

This 'problem' actually cant cause a failure of the driver, but it's always
better to be correct.

Subject: [ARM] pxa/hx4700: use platform_lcd driver

Instead of directly registering an lcd_device, use the platform_lcd driver.
This fixes a broken build in case CONFIG_LCD_CLASS_DEVICE is not enabled.

From 2a23ec3679d84ac243add761fa3d3872cf6dcb11 Mon Sep 17 00:00:00 2001
From: Jonathan McDowell <noodles@earth.li>
Date: Sat, 4 Jul 2009 14:43:56 +0100
Subject: [ARM] pxa: balloon3 (http://balloonboard.org/) base machine support

So, again against latest pxa-linux-2.6/devel, with the following
changes:

 * Move to __raw_readl/__raw_writel for FPGA/CPLD register access
 * Change Toppoly LCD config to be selectable at run time rather than
   compile time.
 * Remove currently unused irq device suspend/resume functions.
 * Strip out unnecessary/duplicated #includes.
 * Some code style cleanups.

Balloon3 (http://balloonboard.org/) base machine support

Subject: USB: ohci-pxa27x: Reconfigure power settings on resume

On resume, the power-related bits in UHCRHDA were not being set, so
they would default to the reset state.  For PXA3xx devices, OCPM must
be cleared, but it was remaining set from resume reset.

Subject: dca: registering requesters in multiple dca domains

This patch enables DCA support on multiple-IOH/multiple-IIO architectures.
It modifies dca module by replacing single dca_providers list
with dca_domains list, each domain containing separate list of providers.
This approach lets dca driver manage multiple domains, i.e. sets of providers
and requesters mapped back to the same PCI root complex device.
The driver takes care to register each requester to a provider
from the same domain.

Subject: drm/i915: Add the enhancement property for SDVO-TV

When the sdvo device is detected as SDVO-TV, we will check whether the
sepecific picture enhancement is supported. If it is supported, we will
add the corresponnding property for SDVO-TV. We will add the following
property for the SDVO-TV enhancements if they are supported:
 * Contrast/Brightness/Saturation/Hue.
 * left/right/top/bottom margin: This is implemented by using the
   horizontal/vertical overscan enhancements. When the overscan
   enhancements are supported, the above properties will be added. This is
   to be compatible with what we have done in integrated-TV.
 * horizontal pos/vertical pos.

Subject: drm/i915: Add the brightness property for SDVO-LVDS

When the sdvo device is detected as SDVO-LVDS, we will check whether the
brightness is supported by issue SDVO enhancement command.
If it is supported, we will add the brightness property and then brightness
can be adjusted.

Subject: drm/i915: Write zero to DPLL_MD Reg for non-SDVO output

When the output device is LVDS, maybe the pixel clock of adjusted_mode will be
less than that in mode. In such case it will set the incorrect multipler factor
in DPLL_MD register.
So the dpll_md_reg will be reset when the output type is non-SDVO

Subject: ACPI button: provide lid status functions

Some drivers need to know when a lid event occurs and get the current
status.  This can be useful for when a platform firmware clobbers some
hardware state at lid time, and a driver needs to restore things when
the lid is opened again.

Subject: drm/i915: force mode set at lid open time

Some laptop platforms will disable pipes and/or planes at lid close time
and not restore them when the lid is opened again.  So catch the lid
event, and if the lid was opened, force a mode restore.

Fixes fdo bug #21230.

Subject: drm/i915: use ACPI LID status for LVDS ->detect hook

We can't load or hotplug detect LVDS like we can other outputs, but if
there's a lid device present we can use it as a proxy.  This allows the
LFP state to be determined at ->detect time, making configurations
requiring manual intervention today "just work" assuming the lid device
status is correct.

Subject: drm/i915: generate a KMS uevent at lid open/close time

With all the other lid pieces in place, it's easy to generate a uevent
for the LVDS connector just like we do for other outputs.  Should make
lid open/close fit in with the rest of a userland based output
reconfiguration scheme.

Subject: drm/i915: framebuffer compression for pre-GM45

This patch adds framebuffer compression (good for about ~0.5W power
savings in the best case) support for pre-GM45 chips.  GM45+ have a new,
more flexible FBC scheme that will be added in a separate patch.

FBC can't always be enabled: the compressed buffer must be physically
contiguous and reside in stolen space.  So if you have a large display
and a small amount of stolen memory, you may not be able to take
advantage of FBC.  In some cases, a BIOS setting controls how much
stolen space is available.  Increasing this to 8 or 16M can help.

Subject: drm/radeon/kms: move modeset init outside of GPU init

We are splitting GPU & modeset init so that it's easier
to abord only remaining GPU init when somethings fails.
We want to always provide enough funcionalities to get
fbcon and a shadowfb X working. Only acceptable error
during initialization are memory allocation failure or
io mapping failure.

Subject: intel-iommu: Disallow interrupt remapping if not all ioapics covered

Current kernel enable interrupt remapping only when all the vt-d unit support
interrupt remapping. So it is reasonable we should also disallow enabling
intr-remapping if there any io-apics that are not listed under vt-d units.
Otherwise we can run into issues.

Subject: intel-iommu: Fix kernel hang if interrupt remapping disabled in BIOS

BIOS clear DMAR table INTR_REMAP flag to disable interrupt remapping. Current
kernel only check interrupt remapping(IR) flag in DRHD's extended capability
register to decide interrupt remapping support or not. But IR flag will not
change when BIOS disable/enable interrupt remapping.

When user disable interrupt remapping in BIOS or BIOS often defaultly disable
interrupt remapping feature when BIOS is not mature.Though BIOS disable
interrupt remapping but intr_remapping_supported function will always report
to OS support interrupt remapping if VT-d2 chipset populated. On this
cases, kernel will continue enable interrupt remapping and result kernel panic.
This bug exist on almost all platforms with interrupt remapping support.

This patch add DMAR table INTR_REMAP flag check before enable interrupt
remapping.

Subject: Btrfs: Allow worker threads to exit when idle

The Btrfs worker threads don't currently die off after they have
been idle for a while, leading to a lot of threads sitting around
doing nothing for each mount.

Also, they are unable to start atomically (from end_io hanlders).

This commit reworks the worker threads so they can be started
from end_io handlers (just setting a flag that asks for a thread
to be added at a later date) and so they can exit if they
have been idle for a long time.

Subject: Btrfs: optimize set extent bit

The Btrfs set_extent_bit call currently searches the rbtree
every time it needs to find more extent_state objects to fill
the requested operation.

This adds a simple test with rb_next to see if the next object
in the tree was adjacent to the one we just found.  If so,
we skip the search and just use the next object.

Subject: Btrfs: keep irqs on more often in the worker threads

The btrfs worker thread spinlock was being used both for the
queueing of IO and for the processing of ordered events.

The ordered events never happen from end_io handlers, and so they
don't need to use the _irq version of spinlocks.  This adds a
dedicated lock to the ordered lists so they don't have to run
with irqs off.

Subject: Btrfs: reduce worker thread spin_lock_irq hold times

This changes the btrfs worker threads to batch work items
into a local list.  It allows us to pull work items in
large chunks and significantly reduces the number of times we
need to take the worker thread spinlock.

Subject: Btrfs: use larger nr_to_write for larger extents

When btrfs fills a large delayed allocation extent, it is a good idea
to try and convince the write_cache_pages caller to go ahead and
write a good chunk of that extent.  The extra IO is basically free
because we know it is contiguous.

Subject: Btrfs: tweak congestion backoff

The btrfs io submission thread tries to back off congested devices in
favor of rotating off to another disk.

But, it tries to make sure it submits at least some IO before rotating
on (the others may be congested too), and so it has a magic number of
requests it tries to write before it hops.

This makes the magic number smaller.  Testing shows that we're spending
too much time on congested devices and leaving the other devices idle.

Subject: Btrfs: switch extent_map to a rw lock

There are two main users of the extent_map tree.  The
first is regular file inodes, where it is evenly spread
between readers and writers.

The second is the chunk allocation tree, which maps blocks from
logical addresses to phyiscal ones, and it is 99.99% reads.

The mapping tree is a point of lock contention during heavy IO
workloads, so this commit switches things to a rw lock.

Subject: Btrfs: Fix new state initialization order

As the extent state tree is manipulated, there are call backs
that are used to take extra actions when different state bits are set
or cleared.  One example of this is a counter for the total number
of delayed allocation bytes in a single inode and in the whole FS.

When new states are inserted, this callback is being done before we
properly setup the new state.  This hasn't caused problems before
because the lock bit was always done first, and the existing call backs
don't care about the lock bit.

This patch makes sure the state is properly setup before using the
callback, which is important for later optimizations that do more work
without using the lock bit.

Subject: Btrfs: reduce CPU usage in the extent_state tree

Btrfs is currently mirroring some of the page state bits into
its extent state tree.  The goal behind this was to use it in supporting
blocksizes other than the page size.

But, we don't currently support that, and we're using quite a lot of CPU
on the rb tree and its spin lock.  This commit starts a series of
cleanups to reduce the amount of work done in the extent state tree as
part of each IO.

This commit:

* Adds the ability to lock an extent in the state tree and also set
other bits.  The idea is to do locking and delalloc in one call

* Removes the EXTENT_WRITEBACK and EXTENT_DIRTY bits.  Btrfs is using
a combination of the page bits and the ordered write code for this
instead.

Subject: Btrfs: cache values for locking extents

Many of the btrfs extent state tree users follow the same pattern.
They lock an extent range in the tree, do some operation and then
unlock.

This translates to at least 2 rbtree searches, and maybe more if they
are doing operations on the extent state tree.  A locked extent
in the tree isn't going to be merged or changed, and so we can
safely return the extent state structure as a cached handle.

This changes set_extent_bit to give back a cached handle, and also
changes both set_extent_bit and clear_extent_bit to use the cached
handle if it is available.

Subject: Btrfs: don't lock bits in the extent tree during writepage

At writepage time, we have the page locked and we have the
extent_map entry for this extent pinned in the extent_map tree.
So, the page can't go away and its mapping can't change.

There is no need for the extra extent_state lock bits during writepage.

Subject: Btrfs: use a cached state for extent state operations during delalloc

This changes the btrfs code to find delalloc ranges in the extent state
tree to use the new state caching code from set/test bit.  It reduces
one of the biggest causes of rbtree searches in the writeback path.

test_range_bit is also modified to take the cached state as a starting
point while searching.

From 8b62b72b26bcd72082c4a69d179dd906bcc22200 Mon Sep 17 00:00:00 2001
From: Chris Mason <chris.mason@oracle.com>
Date: Wed, 2 Sep 2009 16:53:46 -0400
Subject: Btrfs: Use PagePrivate2 to track pages in the data=ordered code.

Btrfs writes go through delalloc to the data=ordered code.  This
makes sure that all of the data is on disk before the metadata
that references it.  The tracking means that we have to make sure
each page in an extent is fully written before we add that extent into
the on-disk btree.

This was done in the past by setting the EXTENT_ORDERED bit for the
range of an extent when it was added to the data=ordered code, and then
clearing the EXTENT_ORDERED bit in the extent state tree as each page
finished IO.

One of the reasons we had to do this was because sometimes pages are
magically dirtied without page_mkwrite being called.  The EXTENT_ORDERED
bit is checked at writepage time, and if it isn't there, our page become
dirty without going through the proper path.

These bit operations make for a number of rbtree searches for each page,
and can cause considerable lock contention.

This commit switches from the EXTENT_ORDERED bit to use PagePrivate2.
As pages go into the ordered code, PagePrivate2 is set on each one.
This is a cheap operation because we already have all the pages locked
and ready to go.

As IO finishes, the PagePrivate2 bit is cleared and the ordered
accoutning is updated for each page.

At writepage time, if the PagePrivate2 bit is missing, we go into the
writepage fixup code to handle improperly dirtied pages.

Subject: Btrfs: Fix extent replacment race

Data COW means that whenever we write to a file, we replace any old
extent pointers with new ones.  There was a window where a readpage
might find the old extent pointers on disk and cache them in the
extent_map tree in ram in the middle of a given write replacing them.

Even though both the readpage and the write had their respective bytes
in the file locked, the extent readpage inserts may cover more bytes than
it had locked down.

This commit closes the race by keeping the new extent pinned in the extent
map tree until after the on-disk btree is properly setup with the new
extent pointers.

Subject: Btrfs: zero page past end of inline file items

When btrfs_get_extent is reading inline file items for readpage,
it needs to copy the inline extent into the page.  If the
inline extent doesn't cover all of the page, that means there
is a hole in the file, or that our file is smaller than one
page.

readpage does zeroing for the case where the file is smaller than one
page, but nobody is currently zeroing for the case where there is
a hole after the inline item.

This commit changes btrfs_get_extent to zero fill the page past
the end of the inline item.

Subject: agp/intel: Fix the pre-9xx chipset flush.

Ever since we enabled GEM, the pre-9xx chipsets (particularly 865) have had
serious stability issues.  Back in May a wbinvd was added to the DRM to
work around much of the problem.  Some failure remained -- easily visible
by dragging a window around on an X -retro desktop, or by looking at bugzilla.

The chipset flush was on the right track -- hitting the right amount of
memory, and it appears to be the only way to flush on these chipsets, but the
flush page was mapped uncached.  As a result, the writes trying to clear the
writeback cache ended up bypassing the cache, and not flushing anything!  The
wbinvd would flush out other writeback data and often cause the data we wanted
to get flushed, but not always.  By removing the setting of the page to UC
and instead just clflushing the data we write to try to flush it, we get the
desired behavior with no wbinvd.

This exports clflush_cache_range(), which was laying around and happened to
basically match the code I was otherwise going to copy from the DRM.

Subject: drm/i915: Only destroy a constructed mmap offset

drm_ht_remove_item() does not handle removing an absent item and the hlist
in particular is incorrectly initialised. The easy remedy is simply skip
calling i915_gem_free_mmap_offset() unless we have actually created the
offset and associated ht entry.

This also fixes the mishandling of a partially constructed offset which
leaves pointers initialized after freeing them along the
i915_gem_create_mmap_offset() error paths.

In particular this should fix the oops found here:

Subject: nfsd41: sunrpc: Added rpc server-side backchannel handling

When the call direction is a reply, copy the xid and call direction into the
req->rq_private_buf.head[0].iov_base otherwise rpc_verify_header returns
rpc_garbage.

Subject: sunrpc/cache: change cache_defer_req to return -ve error, not
 boolean.

As "cache_defer_req" does not sound like a predicate, having it return
a boolean value can be confusing.  It is more consistent to return
0 for success and negative for error.

Exactly what error code to return is not important as we don't
differentiate between reasons why the request wasn't deferred,
we only care about whether it was deferred or not.

Subject: sunrpc/cache: simplify cache_fresh_locked and cache_fresh_unlocked.

The extra call to cache_revisit_request in cache_fresh_unlocked is not
needed, as should have been fairly clear at the time of
   commit 4013edea9a0b6cdcb1fdf5d4011e47e068fd6efb

If there are requests to be revisited, then we can be sure that
CACHE_PENDING is set, so the second call is sufficient.

So remove the first call.
Then remove the 'new' parameter,
then remove the return value for cache_fresh_locked which is only used
to provide the value for 'new'.

This bug does not happen in practice:  All raw1394 clients use

by the client.  This is documented in libraw1394's API reference.

Subject: firewire: ohci: fix Self ID Count register mask (safeguard against
 buffer overflow)

The selfIDSize field of Self ID Count is 9 bits wide, and we are only
interested in the high 8 bits.  Fix the mask accordingly.  The
previously too large mask didn't do damage though because the next few
bits in the register are reserved and therefore zero with presently
existing hardware.

Also, check for the maximum possible self ID count of 252 (according to
OHCI 1.1 clause 11.2 and IEEE 1394a-2000 clause 4.3.4.1, i.e. up to four
self IDs of up to 63 nodes, even though IEEE 1394 up to edition 2008
defines only up to three self IDs per node).  More than 252 self IDs
would only happen if the self ID receive DMA unit malfunctioned, which
would likely be caught by other self ID buffer checks.  However, check
it early to be sure.  More than 253 quadlets would overflow the Topology
Map CSR.

Subject: firewire: core: fix race with parallel PCI device probe

The config ROM buffer received from generate_config_rom is a globally
shared static buffer.  Extend the card_mutex protection in fw_add_card
until after the config ROM was copied into the card driver's buffer.
Otherwise, parallelized card driver probes may end up with ROM contents
that were meant for a different card.

firewire-ohci's card->driver->enable hook is safe to be called within
the card_mutex.  Furthermore, it is safe to reorder card_list update
versus card enable, which simplifies the code a little.

Per SBP-2 clause 5.3, a target shall store 8...32 bytes of status
information.  Trailing zeros after the first 8 bytes don't need to be
stored, they are implicit.  Fix the status write handler to clear all
unwritten status data.

Subject: perf: Add 'perf sched' tool

This turn-key tool allows scheduler measurements to be
conducted and the results be displayed numerically.

First baby step towards that goal: clone the new command off of
perf trace.

Fix a few other details along the way:

 - add (minimal) perf trace documentation

 - reorder a few places

 - list perf trace in the mainporcelain list as well
   as it's a very useful utility.

Subject: perf sched: Import schedbench.c

Import the schedbench.c tool that i wrote some time ago to
simulate scheduler behavior but never finished. It's a good
basis for perf sched nevertheless.

Most of its guts are not hooked up to the perf event loop
yet - that will be done in the patches to come.

Subject: perf sched: Implement the scheduling workload replay engine

Integrate the schedbench.c bits with the raw trace events
that we get from the perf machinery, and activate the
workload replayer/simulator.

Example of a captured 'make -j' workload:

$ perf sched

  run measurement overhead: 90 nsecs
  sleep measurement overhead: 2724743 nsecs
  the run test took 1000081 nsecs
  the sleep test took 2981111 nsecs
  version = 0.5

  nr_sleep_events:      66
  nr_wakeup_events:     9
  target-less wakeups:  71
  multi-target wakeups: 47

I.e. we successfully analyzed the trace, replayed it
via real threads and measured the replayed workload's
scheduling properties.

This is how it looked like in 'top' output:

There's still various kinks in it - more patches to come.

Subject: perf tools: Allow the specification of all tracepoints at once

Currently, when one wants to activate every tracepoint
counters of a subsystem from perf record, the current sequence
is needed:

  perf record -e subsys:ev1 -e subsys:ev2 -e subsys:ev3

This may annoy the most patient of us.

Now we can just do:

  perf record -e subsys:*

Subject: perf sched: Fix bad event alignment

perf sched raises the following error when it meets a sched
switch event:

perf: builtin-sched.c:286: register_pid: Assertion `!(pid >= 65536)' failed.
Abandon

Currently in x86-64, the sched switch events have a hole in the
middle of the structure:

	u16 common_type;
	u8 common_flags;
	u8 common_preempt_count;
	u32 common_pid;
	u32 common_tgid;

	char prev_comm[16];
	u32 prev_pid;
	u32 prev_prio;
			<--- there
	u64 prev_state;
	char next_comm[16];
	u32 next_pid;
	u32 next_prio;

Gcc inserts a 4 bytes hole there for prev_state to be u64
aligned. And the events are exported to userspace with this
hole.

But in userspace, from perf sched, we fetch it using a
structure that has a new field in the beginning: u32 size. This
is because our trace is exported with its size as a field. But
now that we have this new field, the hole in the middle
disappears because it makes prev_state becoming well aligned.

And since we are using a pointer to the raw trace using this
struct, instead of reading prev_state, we are reading the hole.

We could fix it by keeping the size seperate from the struct
but actually there a lot of other potential problems: some
fields may be saved as long in a 64 bits system and later read
as long in a 32 bits system. Also this direct cast doesn't care
about the endianness differences between the host traced
machine and the machine in which we do the post processing.

So instead of using such dangerous direct casts, fetch the
values using the trace parsing API that already takes care of
all these problems.

Subject: perf sched: Make it easier to plug in new sub profilers

Create a sched event structure of handlers in which various
sched events reader can plug their own callbacks.

This makes easier the addition of new perf sched sub commands.

Subject: perf sched: Add sched latency profiling

Add the -l --latency option that reports statistics about the
scheduler latencies.

For now, the latencies are measured in the following sequence
scope:

- task A is sleeping (D or S state)
- task B wakes up A
         ^
         |
         |

   latency timeframe

         |
         |
         v
- task A is scheduled in

Start by recording every scheduler events:

	perf record -e sched:*

and then fetch the results:

	perf sched -l

 Tasks                     count          total              avg            max

The snapshot are in nanoseconds.

- Count: number of snapshots taken for the given task
- Total: total latencies in nanosec
- Avg  : average of latency between wake up and sched in
- Max  : max snapshot latency

Subject: perf sched: Clean up latency and replay sub-commands

- Separate the latency and the replay commands more cleanly

 - Use consistent naming

 - Display help page on 'perf sched' outlining comments,
   instead of aborting

Subject: perf sched: Rename struct lat_snapshot to struct work atoms

To measures the latencies, we capture the sched atoms data into
a specific structure named struct lat_snapshot.

As this structure can be used for other purposes of scheduler
profiling and mirrors what happens in a thread work atom, lets
rename it to struct work_atom and propagate this renaming in
other functions and structures names to keep it coherent.

Subject: perf sched: Add involuntarily sleeping task in work atoms

Currently in perf sched, we are measuring the scheduler wakeup
latencies.

Now we also want measure the time a task wait to be scheduled
after it gets preempted.

Subject: perf sched: Fix nsec to msec conversion

We are dividing a time in ns by 1e9. This is a nsec to sec
conversion. What we want is msecs. Fix it by dividing by 1e6.

you can sort either by number of switches, latency average,
latency maximum, runtime.

Subject: perf sched: Add 'perf sched latency' and 'perf sched replay'

Separate the option parsing cleanly and add two variants:

 - 'perf sched latency' (can be abbreviated via 'perf sched lat')
 - 'perf sched replay'  (can be abbreviated via 'perf sched rep')

Also add a repeat count option to replay and add a separation
set of options for replay.

Do the sorting setup only in the latency sub-command.

Display separate help screens for 'perf sched' and
'perf sched replay -h' - i.e. further separation of the
sub-commands.

Subject: perf sched: Finish latency => atom rename and misc cleanups

- Rename 'latency' field/variable names to the better 'atom' ones

 - Reduce the number of #include lines and consolidate them

 - Gather file scope variables at the top of the file

 - Remove unused bits

No change in functionality.

Subject: perf sched: Implement the 'perf sched record' subcommand

Implement the 'perf sched record' subcommand that adds a
default list of events, turns on raw sampling and system-wide
tracing and passes off the rest of the command to perf record.

This is more convenient than having to specify the events all
the time.

Before:

 $ perf record -a -R -e sched:sched_switch:r -e sched:sched_stat_wait:r -e sched:sched_stat_sleep:r -e sched:sched_stat_iowait:r -e sched:sched_process_exit:r -e sched:sched_process_fork:r -e sched:sched_wakeup:r -e sched:sched_migrate_task:r -c 1 sleep 1

After:

 $ perf sched record -f sleep 1

Also fix an assumption in the event string parser that assumed
that strings passed in can be modified. (In this case they wont
be as they come from a readonly constant section.)

 SYNOPSIS
 --------
 [verse]
-'perf sched' [-i <file> | --input=file] symbol_name
+'perf sched' {record|latency|replay|trace}
 
 DESCRIPTION
 -----------
-This command reads the input file and displays the latencies recorded.
+There's four variants of perf sched:
+
+  'perf sched record <command>' to record the scheduling events
+  of an arbitrary workload.
+
+  'perf sched latency' to report the per task scheduling latencies
+  and other scheduling properties of the workload.
+
+  'perf sched trace' to see a detailed trace of the workload that
+  was recorded.
+
+  'perf sched replay' to simulate the workload that was recorded
+  via perf sched record. (this is done by starting up mockup threads
+  that mimic the workload based on the events in the trace. These
+  threads can then replay the timings (CPU runtime and sleep patterns)
+  of the workload as it occured when it was recorded - and can repeat
+  it a number of times, measuring its performance.)

Subject: drm/radeon/kms: move mtrr range add and memory information

Move mtrr range and memory information printing to radeon_object_init,
this are memory information and initialization common to all GPU and
they better fit in this function. Will also prevent code duplication
with upcoming init path changes.

airlied: fixed warning introduced

Subject: drm/radeon/kms: cleanup - remove radeon_share.h

radeon_share.h was begining to give problem with include order in
respect of radeon.h. It's easier and also i think cleaner to move
what was in radeon_share.h into radeon.h. At the same time use the
extern keyword for function shared accross the module.

Subject: perf tools: Add an option to multiplex counters in a single channel

Add an option to multiplex counters output in the channel of
the group leader, ie: the first counter opened:

	-M --multiplex

The effect is better serialized samples. This is especially
useful for tracepoint samples that need to be well serialized
for their post-processing.

Also make use of this option in 'perf sched'.

Subject: perf tools: Fix processing of randomly serialized sched traces

Currently it's possible to meet such too high latency results
with 'perf sched latency'.

 -----------------------------------------------------------------------------------
 Task              |  Runtime ms | Switches | Average delay ms | Maximum delay ms |
 -----------------------------------------------------------------------------------
 xfce4-panel       |    0.222 ms |        2 | avg: 4718.345 ms | max: 9436.493 ms |
 scsi_eh_3         |    3.962 ms |       36 | avg:   55.957 ms | max: 1977.829 ms |

The origin is on traces that are sometimes badly serialized across cpus.
For example the raw traces that raised such results for xfce4-panel:

(1)          [init]-0     [000]  1494.663899990: sched_switch: task swapper:0 [140] (R) ==> xfce4-panel:4569 [120]
(2)     xfce4-panel-4569  [000]  1494.663928373: sched_switch: task xfce4-panel:4569 [120] (S) ==> swapper:0 [140]
(3)            Xorg-4276  [001]  1494.663860125: sched_wakeup: task xfce4-panel:4569 [120] success=1 [000]
(4)            Xorg-4276  [001]  1504.098252756: sched_wakeup: task xfce4-panel:4569 [120] success=1 [000]
(5)            perf-5219  [000]  1504.100353302: sched_switch: task perf:5219 [120] (S) ==> xfce4-panel:4569 [120]

The traces are processed in the order they arrive. Then in (2),
xfce4-panel sleeps, it is first waken up in (3) and eventually
scheduled in (5).

The latency reported is then 1504 - 1495 = 9 secs, as reported by perf
sched. But this is wrong, we are confident in the fact the traces are
nicely serialized while we should actually more trust the timestamps.

If we reorder by timestamps we get:

(1)            Xorg-4276  [001]  1494.663860125: sched_wakeup: task xfce4-panel:4569 [120] success=1 [000]
(2)          [init]-0     [000]  1494.663899990: sched_switch: task swapper:0 [140] (R) ==> xfce4-panel:4569 [120]
(3)     xfce4-panel-4569  [000]  1494.663928373: sched_switch: task xfce4-panel:4569 [120] (S) ==> swapper:0 [140]
(4)            Xorg-4276  [001]  1504.098252756: sched_wakeup: task xfce4-panel:4569 [120] success=1 [000]
(5)            perf-5219  [000]  1504.100353302: sched_switch: task perf:5219 [120] (S) ==> xfce4-panel:4569 [120]

Now the trace make more sense, xfce4-panel is sleeping. Then it is
woken up in (1), scheduled in (2)
It goes to sleep in (3), woken up in (4) and scheduled in (5).

Now, latency captured between (1) and (2) is of 39 us.
And between (4) and (5) it is 2.1 ms.

Such pattern of bad serializing is the origin of the high latencies
reported by perf sched.

Basically, we need to check whether wake up time is higher than
schedule out time. If it's not the case, we need to tag the current
work atom as invalid.

Beside that, we may need to work later on a better ordering of the
traces given by the kernel.

After this patch:

xfce4-session     |    0.221 ms |        1 | avg:    0.538 ms | max:    0.538 ms |

Subject: perf tools: Implement counter output multiplexing

Finish the -M/--multiplex option implementation:

 - separate it out from group_fd

 - correctly set it via the ioctl and dont mmap counters that
   are multiplexed

 - modify the perf record event loop to deal with buffer-less
   counters.

 - remove the -g option from perf sched record

 - account for unordered events in perf sched latency

 - (add -f to perf sched record to ease measurements)

 - skip idle threads (pid==0) in latency output

The result is better latency output by 'perf sched latency':

Subject: perf sched: Print PIDs too

Often it's useful to know the PID of the task as well - print it
out too.

( While at it, reformat the output to be a bit more
  paste-into-commit-logs friendly. )

Subject: drm/radeon/kms: clear confusion in GART init/deinit path

GART static one time initialization was mixed up with GART
enabling/disabling which could happen several time for instance
during suspend/resume cycles. This patch splits all GART
handling into 4 differents function. gart_init is for one
time initialization, gart_deinit is called upon module unload
to free resources allocated by gart_init, gart_enable enable
the GART and is intented to be call after first initialization
and at each resume cycle or reset cycle. Finaly gart_disable
stop the GART and is intended to be call at suspend time or
when unloading the module.

Subject: drm/radeon/kms: add 32/64 ioctl support.

Although the new radeon driver ioctls don't need this, some of
the drm initialisation ioctls require it, so add this to make them
work.

Subject: HID: fix non-atomic allocation in hid_input_report

'interrupt' variable can't be used to safely determine whether
we are running in atomic context or not, as we might be called from
during control transfer completion through hid_ctrl() in atomic
context with interrupt == 0.

Subject: hrtimer: Eliminate needless reprogramming of clock events device

On NOHZ systems the following timers,

-  tick_nohz_restart_sched_tick (tick_sched_timer)
-  hrtimer_start (tick_sched_timer)

are reprogramming the clock events device far more often than needed.
No specific test case was required to observe this effect. This
occurres because there was no check to see if the currently removed or
restarted hrtimer was:

1) the one which previously armed the clock events device.
2) going to be replaced by another timer which has the same expiry time.

Avoid the reprogramming in hrtimer_force_reprogram when the new expiry
value which is evaluated from the clock bases is equal to
cpu_base->expires_next. This results in faster application startup
time by ~4%.

[ tglx: simplified initial solution ]

commit ac68392460ffefed13020967bae04edc4d3add06 ("[CIFS] Allow raw
ntlmssp code to be enabled with sec=ntlmssp") added a new bit to the
allowed security flags mask but seems to have inadvertently removed
Lanman security from the allowed flags. Add it back.

Subject: cifs: fix oplock request handling in posix codepath

cifs_posix_open takes a "poplock" argument that's intended to be used in
the actual posix open call to set the "Flags" field. It ignores this
value however and declares an "oplock" parameter on the stack that it
passes uninitialized to the CIFSPOSIXOpen function. Not only does this
mean that the oplock request flags are bogus, but the result that's
expected to be in that variable is unchanged.

Fix this, and also clean up the type of the oplock parameter used. Since
it's expected to be __u32, we should use that everywhere and not
implicitly cast it from a signed type.

Subject: cifs: have cifsFileInfo hold an extra inode reference

It's possible that this struct will outlive the filp to which it is
attached. If it does and it needs to do some work on the inode, then
it'll need a reference.

Subject: ARM: 5701/1: ARM: copy_page.S: take into account the size of the
 cache line

Optimized version of copy_page() was written with assumption that cache
line size is 32 bytes. On Cortex-A8 cache line size is 64 bytes.

This patch tries to generalize copy_page() to work with any cache line
size if cache line size is multiple of 16 and page size is multiple of
two cache line size.

After this optimization we've got ~25% speedup on OMAP3(tested in
userspace).

There is test for kernelspace which trigger copy-on-write after fork():

 #include <stdlib.h>
 #include <string.h>
 #include <unistd.h>

 #define BUF_SIZE (10000*4096)
 #define NFORK 200

 int main(int argc, char **argv)
 {
         char *buf = malloc(BUF_SIZE);
         int i;

         memset(buf, 0, BUF_SIZE);

         for(i = 0; i < NFORK; i++) {
                 if (fork()) {
                         wait(NULL);
                 } else {
                         int j;

                         for(j = 0; j < BUF_SIZE; j+= 4096)
                                 buf[j] = (j & 0xFF) + 1;
                         break;
                 }
         }

         free(buf);
         return 0;
 }

Before optimization this test takes ~66 seconds, after optimization
takes ~56 seconds.

+Written by Linus Walleij <linus.walleij@stericsson.com>
+
+Some ARM SoC:s have a so-called TCM (Tightly-Coupled Memory).
+This is usually just a few (4-64) KiB of RAM inside the ARM
+processor.
+
+Due to being embedded inside the CPU The TCM has a
+Harvard-architecture, so there is an ITCM (instruction TCM)
+and a DTCM (data TCM). The DTCM can not contain any
+instructions, but the ITCM can actually contain data.
+The size of DTCM or ITCM is minimum 4KiB so the typical
+minimum configuration is 4KiB ITCM and 4KiB DTCM.
+
+ARM CPU:s have special registers to read out status, physical
+location and size of TCM memories. arch/arm/include/asm/cputype.h
+defines a CPUID_TCM register that you can read out from the
+system control coprocessor. Documentation from ARM can be found
+at http://infocenter.arm.com, search for "TCM Status Register"
+to see documents for all CPUs. Reading this register you can
+determine if ITCM (bit 0) and/or DTCM (bit 16) is present in the
+machine.
+
+There is further a TCM region register (search for "TCM Region
+Registers" at the ARM site) that can report and modify the location
+size of TCM memories at runtime. This is used to read out and modify
+TCM location and size. Notice that this is not a MMU table: you
+actually move the physical location of the TCM around. At the
+place you put it, it will mask any underlying RAM from the
+CPU so it is usually wise not to overlap any physical RAM with
+the TCM. The TCM memory exists totally outside the MMU and will
+override any MMU mappings.
+
+Code executing inside the ITCM does not "see" any MMU mappings
+and e.g. register accesses must be made to physical addresses.
+
+TCM is used for a few things:
+
+- FIQ and other interrupt handlers that need deterministic
+  timing and cannot wait for cache misses.
+
+- Idle loops where all external RAM is set to self-refresh
+  retention mode, so only on-chip RAM is accessible by
+  the CPU and then we hang inside ITCM waiting for an
+  interrupt.
+
+- Other operations which implies shutting off or reconfiguring
+  the external RAM controller.
+
+There is an interface for using TCM on the ARM architecture
+in <asm/tcm.h>. Using this interface it is possible to:
+
+- Define the physical address and size of ITCM and DTCM.
+
+- Tag functions to be compiled into ITCM.
+
+- Tag data and constants to be allocated to DTCM and ITCM.
+
+- Have the remaining TCM RAM added to a special
+  allocation pool with gen_pool_create() and gen_pool_add()
+  and provice tcm_alloc() and tcm_free() for this
+  memory. Such a heap is great for things like saving
+  device state when shutting off device power domains.
+
+A machine that has TCM memory shall select HAVE_TCM in
+arch/arm/Kconfig for itself, and then the
+rest of the functionality will depend on the physical
+location and size of ITCM and DTCM to be defined in
+mach/memory.h for the machine. Code that needs to use
+TCM shall #include <asm/tcm.h> If the TCM is not located
+at the place given in memory.h it will be moved using
+the TCM Region registers.
+
+Functions to go into itcm can be tagged like this:
+int __tcmfunc foo(int bar);
+
+Variables to go into dtcm can be tagged like this:
+int __tcmdata foo;
+
+Constants can be tagged like this:
+int __tcmconst foo;
+
+To put assembler into TCM just use
+.section ".tcm.text" or .section ".tcm.data"
+respectively.
+
+Example code:
+
+#include <asm/tcm.h>
+
+/* Uninitialized data */
+static u32 __tcmdata tcmvar;
+/* Initialized data */
+static u32 __tcmdata tcmassigned = 0x2BADBABEU;
+/* Constant */
+static const u32 __tcmconst tcmconst = 0xCAFEBABEU;
+
+static void __tcmlocalfunc tcm_to_tcm(void)
+{
+	int i;
+	for (i = 0; i < 100; i++)
+		tcmvar ++;
+}
+
+static void __tcmfunc hello_tcm(void)
+{
+	/* Some abstract code that runs in ITCM */
+	int i;
+	for (i = 0; i < 100; i++) {
+		tcmvar ++;
+	}
+	tcm_to_tcm();
+}
+
+static void __init test_tcm(void)
+{
+	u32 *tcmem;
+	int i;
+
+	hello_tcm();
+	printk("Hello TCM executed from ITCM RAM\n");
+
+	printk("TCM variable from testrun: %u @ %p\n", tcmvar, &tcmvar);
+	tcmvar = 0xDEADBEEFU;
+	printk("TCM variable: 0x%x @ %p\n", tcmvar, &tcmvar);
+
+	printk("TCM assigned variable: 0x%x @ %p\n", tcmassigned, &tcmassigned);
+
+	printk("TCM constant: 0x%x @ %p\n", tcmconst, &tcmconst);
+
+	/* Allocate some TCM memory from the pool */
+	tcmem = tcm_alloc(20);
+	if (tcmem) {
+		printk("TCM Allocated 20 bytes of TCM @ %p\n", tcmem);
+		tcmem[0] = 0xDEADBEEFU;
+		tcmem[1] = 0x2BADBABEU;
+		tcmem[2] = 0xCAFEBABEU;
+		tcmem[3] = 0xDEADBEEFU;
+		tcmem[4] = 0x2BADBABEU;
+		for (i = 0; i < 5; i++)
+			printk("TCM tcmem[%d] = %08x\n", i, tcmem[i]);
+		tcm_free(tcmem, 20);
+	}
+}

Subject: ARM: 5697/1: MMCI Break out clock divider setup

This breaks out the clock divider set-up code from the
mmci_set_ios() code and surrounds the two register
writes with a host lock so we don't get collisions if
(in future code) two code paths want to change the
clock divider at the same time as can be the case if
we get something like pre/post- clock frequency change
notifications soonish.

Subject: ARM: 5698/1: MMCI pass capabilities in platform data

This makes it possible to pass down the host controller
capabilities for the MMCI driver using the platform data. It
also provides the capabilties for the U300 implementation as an
example, and makes sure the 4bit wide mode is set if this is
requested by the ios() now that we can actually set that
capability for a platform.

Subject: drm/radeon/kms: IB locking dumps out a lockdep ordering issue

We sometimes lock IB then the ring and sometimes the ring then
the IB. This is mostly due to the IB locking not being well defined
about what data in the structs it actually locks. Define what I
believe is the correct behaviour and gets rid of the lock dep ordering
warning.

Subject: Btrfs: fix async worker startup race

After a new worker thread starts, it is placed into the
list of idle threads.  But, this may race with a
check for idle done by the worker thread itself, resulting
in a double list_add operation.

This fix adds a check to make sure the idle thread addition
is done properly.

Subject: Btrfs: Fix async thread shutdown race

It was possible for an async worker thread to be selected to
receive a new work item, but exit before the work item was
actually placed into that thread's work list.

This commit fixes the race by incrementing the num_pending
counter earlier, and making sure to check the number of pending
work items before a thread exits.

Subject: nfsd4: fix null dereference creating nfsv4 callback client

On setting up the callback to the client, we attempt to use the same
authentication flavor the client did.  We find an rpc cred to use by
calling rpcauth_lookup_credcache(), which assumes that the given
authentication flavor has a credentials cache.  However, this is not
required to be true--in particular, auth_null does not use one.
Instead, we should call the auth's lookup_cred() method.

Without this, a client attempting to mount using nfsv4 and auth_null
triggers a null dereference.

Subject: nfsd4: use common rpc_cred for all callbacks

Callbacks are always made using the machine's identity, so we can use a
single auth_generic credential shared among callbacks to all clients and
let the rpc code take care of the rest.

Subject: nfsd41: Backchannel: callback infrastructure

Keep the xprt used for create_session in cl_cb_xprt.
Mark cl_callback.cb_minorversion = 1 and remember
the client provided cl_callback.cb_prog rpc program number.
Use it to probe the callback path.

Use the client's network address to initialize as the
callback's address as expected by the xprt creation
routines.

Define xdr sizes and code nfs4_cb_compound header to be able
to send a null callback rpc.

Subject: nfsd41: Backchannel: Add sequence arguments to callback RPC arguments

Follow the model we use in the client. Make the sequence arguments
part of the regular RPC arguments.  None of the callbacks that are
soon to be implemented expect results that need to be passed back
to the caller, so we don't define a separate RPC results structure.
For session validation, the cb_sequence decoding will use a pointer
to the sequence arguments that are part of the RPC argument.

Subject: nfsd41: Backchannel: Setup sequence information

Follows the model used by the NFS client.  Setup the RPC prepare and done
function pointers so that we can populate the sequence information if
minorversion == 1.  rpc_run_task() is then invoked directly just like
existing NFS client operations do.

nfsd4_cb_prepare() determines if the sequence information needs to be setup.
If the slot is in use, it adds itself to the wait queue.

nfsd4_cb_done() wakes anyone sleeping on the callback channel wait queue
after our RPC reply has been received.  It also sets the task message
result pointer to NULL to clearly indicate we're done using it.

Subject: nfsd41: Backchannel: cb_sequence callback

Implement the cb_sequence callback conforming to draft-ietf-nfsv4-minorversion1

Note: highest slot id and target highest slot id do not have to be 0
as was previously implemented.  They can be greater than what the
nfs server sent if the client supports a larger slot table on the
backchannel.  At this point we just ignore that.

Subject: perf sched: Account for lost events, increase default buffering

Output such lost event and state machine weirdness stats:

   TOTAL:                |  14974.910 ms |    46384 |
  ---------------------------------------------------
   INFO: 8.865% lost events (19132 out of 215819, in 8 chunks)
   INFO: 0.198% state machine bugs (49 out of 24708) (due to lost events?)

And increase buffering to -m 1024 (4 MB) by default. Since we
use output multiplexing that kind of space is needed.

Subject: HWPOISON: Add page flag for poisoned pages

Hardware poisoned pages need special handling in the VM and shouldn't be
touched again. This requires a new page flag. Define it here.

The page flags wars seem to be over, so it shouldn't be a problem
to get a new one.

v2: Add TestSetHWPoison (suggested by Johannes Weiner)

Subject: HWPOISON: Export some rmap vma locking to outside world

Needed for later patch that walks rmap entries on its own.

This used to be very frowned upon, but memory-failure.c does
some rather specialized rmap walking and rmap has been stable
for quite some time, so I think it's ok now to export it.

Subject: HWPOISON: Add support for poison swap entries v2

Memory migration uses special swap entry types to trigger special actions on
page faults. Extend this mechanism to also support poisoned swap entries, to
trigger poison handling on page faults. This allows follow-on patches to
prevent processes from faulting in poisoned pages again.

v2: Fix overflow in MAX_SWAPFILES (Fengguang Wu)
v3: Better overflow fix (Hidehiro Kawai)

Subject: HWPOISON: Add new SIGBUS error codes for hardware poison signals

Add new SIGBUS codes for reporting machine checks as signals. When
the hardware detects an uncorrected ECC error it can trigger these
signals.

This is needed for telling KVM's qemu about machine checks that happen to
guests, so that it can inject them, but might be also useful for other programs.
I find it useful in my test programs.

This patch merely defines the new types.

- Define two new si_codes for SIGBUS.  BUS_MCEERR_AO and BUS_MCEERR_AR
* BUS_MCEERR_AO is for "Action Optional" machine checks, which means that some
corruption has been detected in the background, but nothing has been consumed
so far. The program can ignore those if it wants (but most programs would
already get killed)
* BUS_MCEERR_AR is for "Action Required" machine checks. This happens
when corrupted data is consumed or the application ran into an area
which has been known to be corrupted earlier. These require immediate
action and cannot just returned to. Most programs would kill themselves.
- They report the address of the corruption in the user address space
in si_addr.
- Define a new si_addr_lsb field that reports the extent of the corruption
to user space. That's currently always a (small) page. The user application
cannot tell where in this page the corruption happened.

AK: I plan to write a man page update before anyone asks.

Subject: HWPOISON: Add basic support for poisoned pages in fault handler v3

- Add a new VM_FAULT_HWPOISON error code to handle_mm_fault. Right now
architectures have to explicitely enable poison page support, so
this is forward compatible to all architectures. They only need
to add it when they enable poison page support.
- Add poison page handling in swap in fault code

v2: Add missing delayacct_clear_flag (Hidehiro Kawai)
v3: Really use delayacct_clear_flag (Hidehiro Kawai)

Subject: HWPOISON: Add poison check to page fault handling

Bail out early when hardware poisoned pages are found in page fault handling.
Since they are poisoned they should not be mapped freshly into processes,
because that would cause another (potentially deadly) machine check

This is generally handled in the same way as OOM, just a different
error code is returned to the architecture code.

v2: Do a page unlock if needed (Fengguang Wu)

Subject: HWPOISON: Use bitmask/action code for try_to_unmap behaviour

try_to_unmap currently has multiple modi (migration, munlock, normal unmap)
which are selected by magic flag variables. The logic is not very straight
forward, because each of these flag change multiple behaviours (e.g.
migration turns off aging, not only sets up migration ptes etc.)
Also the different flags interact in magic ways.

A later patch in this series adds another mode to try_to_unmap, so
this becomes quickly unmanageable.

Replace the different flags with a action code (migration, munlock, munmap)
and some additional flags as modifiers (ignore mlock, ignore aging).
This makes the logic more straight forward and allows easier extension
to new behaviours. Change all the caller to declare what they want to
do.

This patch is supposed to be a nop in behaviour. If anyone can prove
it is not that would be a bug.

When a page has the poison bit set replace the PTE with a poison entry.
This causes the right error handling to be done later when a process runs
into it.

later) (Fengguang)

Subject: HWPOISON: check and isolate corrupted free pages v2

If memory corruption hits the free buddy pages, we can safely ignore them.
No one will access them until page allocation time, then prep_new_page()
will automatically check and isolate PG_hwpoison page for us (for 0-order
allocation).

This patch expands prep_new_page() to check every component page in a high
order page allocation, in order to completely stop PG_hwpoison pages from
being recirculated.

Note that the common case -- only allocating a single page, doesn't
do any more work than before. Allocating > order 0 does a bit more work,
but that's relatively uncommon.

This simple implementation may drop some innocent neighbor pages, hopefully
it is not a big problem because the event should be rare enough.

This patch adds some runtime costs to high order page users.

[AK: Improved description]

v2: Andi Kleen:
Port to -mm code
Move check into separate function.
Don't dump stack in bad_pages for hwpoisoned pages.

Subject: HWPOISON: Define a new error_remove_page address space op for async
 truncation

Truncating metadata pages is not safe right now before
we haven't audited all file systems.

To enable truncation only for data address space define
a new address_space callback error_remove_page.

This is used for memory_failure.c memory error handling.

This can be then set to truncate_inode_page()

This patch just defines the new operation and adds documentation.

Callers and users come in followon patches.

Subject: HWPOISON: shmem: call set_page_dirty() with locked page

The dirtying of page and set_page_dirty() can be moved into the page lock.

- In shmem_write_end(), the page was dirtied while the page lock was held,
  but it's being marked dirty just after dropping the page lock.
- In shmem_symlink(), both dirtying and marking can be moved into page lock.

It's valuable for the hwpoison code to know whether one bad page can be dropped
without losing data. It mainly judges by testing the PG_dirty bit after taking
the page lock. So it becomes important that the dirtying of page and the
marking of dirtiness are both done inside the page lock. Which is a common
practice, but sadly not a rule.

The noticeable exceptions are
- mapped pages
- pages with buffer_heads
The above pages could go dirty at any time. Fortunately the hwpoison will
unmap the page and release the buffer_heads beforehand anyway.

Many other types of pages (eg. metadata pages) can also be dirtied at will by
their owners, the hwpoison code cannot do meaningful things to them anyway.
Only the dirtiness of pagecache pages owned by regular files are interested.

Subject: HWPOISON: Add PR_MCE_KILL prctl to control early kill behaviour per
 process

This allows processes to override their early/late kill
behaviour on hardware memory errors.

Typically applications which are memory error aware is
better of with early kill (see the error as soon
as possible), all others with late kill (only
see the error when the error is really impacting execution)

There's a global sysctl, but this way an application
can set its specific policy.

We're using two bits, one to signify that the process
stated its intention and that

I also made the prctl future proof by enforcing
the unused arguments are 0.

The state is inherited to children.

Note this makes us officially run out of process flags
on 32bit, but the next patch can easily add another field.

Manpage patch will be supplied separately.

Subject: HWPOISON: The high level memory error handler in the VM v7

Add the high level memory handler that poisons pages
that got corrupted by hardware (typically by a two bit flip in a DIMM
or a cache) on the Linux level. The goal is to prevent everyone
from accessing these pages in the future.

This done at the VM level by marking a page hwpoisoned
and doing the appropriate action based on the type of page
it is.

The code that does this is portable and lives in mm/memory-failure.c

To quote the overview comment:

High level machine check handler. Handles pages reported by the
hardware as being corrupted usually due to a 2bit ECC memory or cache
failure.

This focuses on pages detected as corrupted in the background.
When the current CPU tries to consume corruption the currently
running process can just be killed directly instead. This implies
that if the error cannot be handled for some reason it's safe to
just ignore it because no corruption has been consumed yet. Instead
when that happens another machine check will happen.

Handles page cache pages in various states. The tricky part
here is that we can access any page asynchronous to other VM
users, because memory failures could happen anytime and anywhere,
possibly violating some of their assumptions. This is why this code
has to be extremely careful. Generally it tries to use normal locking
rules, as in get the standard locks, even if that means the
error handling takes potentially a long time.

Some of the operations here are somewhat inefficient and have non
linear algorithmic complexity, because the data structures have not
been optimized for this case. This is in particular the case
for the mapping from a vma to a process. Since this case is expected
to be rare we hope we can get away with this.

There are in principle two strategies to kill processes on poison:
- just unmap the data and wait for an actual reference before
killing
- kill as soon as corruption is detected.
Both have advantages and disadvantages and should be used
in different situations. Right now both are implemented and can
be switched with a new sysctl vm.memory_failure_early_kill
The default is early kill.

The patch does some rmap data structure walking on its own to collect
processes to kill. This is unusual because normally all rmap data structure
knowledge is in rmap.c only. I put it here for now to keep
everything together and rmap knowledge has been seeping out anyways

Includes contributions from Johannes Weiner, Chris Mason, Fengguang Wu,
Nick Piggin (who did a lot of great work) and others.

Subject: HWPOISON: Enable .remove_error_page for migration aware file systems

Enable removing of corrupted pages through truncation
for a bunch of file systems: ext*, xfs, gfs2, ocfs2, ntfs
These should cover most server needs.

I chose the set of migration aware file systems for this
for now, assuming they have been especially audited.
But in general it should be safe for all file systems
on the data area that support read/write and truncate.

Caveat: the hardware error handler does not take i_mutex
for now before calling the truncate function. Is that ok?

Subject: HWPOISON: Enable error_remove_page for NFS

Enable hardware memory error handling for NFS

Truncation of data pages at runtime should be safe in NFS,
even when it doesn't support migration so far.

Trond tells me migration is also queued up for 2.6.32.

Subject: HWPOISON: Add madvise() based injector for hardware poisoned pages v4

Impact: optional, useful for debugging

Add a new madvice sub command to inject poison for some
pages in a process' address space.  This is useful for
testing the poison page handling.

This patch can allow root to tie up large amounts of memory.
I got feedback from container developers and they didn't see any
problem.

v2: Use write flag for get_user_pages to make sure to always get
a fresh page
v3: Don't request write mapping (Fengguang Wu)
v4: Move MADV_* number to avoid conflict with KSM (Hugh Dickins)

Subject: HWPOISON: Add simple debugfs interface to inject hwpoison on arbitary
 PFNs

Useful for some testing scenarios, although specific testing is often
done better through MADV_POISON

This can be done with the x86 level MCE injector too, but this interface
allows it to do independently from low level x86 changes.

v2: Add module license (Haicheng Li)

Subject: perf sched: Add 'perf sched map' scheduling event map printout

This prints a textual context-switching outline of workload
captured via perf sched record.

For example, on a 16 CPU box it outputs:

Columns stand for individual CPUs, from CPU0 to CPU15, and the
two-letter shortcuts stand for tasks that are running on a CPU.

'*' denotes the CPU that had the event.

A dot signals an idle CPU.

New tasks are assigned new two-letter shortcuts - when they occur
first they are printed. In the above example 'T1' stood for irqbalance:

      T1 => irqbalance:2089

Subject: md/raid6: eliminate BUG_ON with side effect

As pointed out by Neil it should be possible to build a driver with all
BUG_ON statements deleted.  It's bad form to have a BUG_ON with a side
effect.

Subject: md/raid6: cleanup ops_run_compute6_2

Neil says:
	"It is correct as it stands, but the fact that every branch in
	 the 'if' part ends with a 'return' isn't immediately obvious,
	 so it is clearer if we are explicit about the if / then / else
	 structure."

With the addition of ioat_max_alloc_order it is not clear what the
maximum allocation order is, so document that in the modinfo.  Also take

Subject: raid6test: fix stack overflow

Testing on x86_64 with NDISKS=255 yields:

   do_IRQ: modprobe near stack overflow (cur:ffff88007d19c000,sp:ffff88007d19c128)

...and eventually

   general protection fault: 0000 [#1]

Moving the scribble buffers off the stack allows the test to complete
successfully.

Subject: ARM: S3C64XX: Provide for board-specific IRQs

Set up some IRQ space to allocation to off-SoC interrupt controllers.
Default this to 16 IRQs. If individual boards require more than this
then they will need to modify this file so allocating a small number
helps reduce the number of modifications required.

Subject: ASoC: Blackfin I2S: add lost platform_device parameter to resume
 function

Commit dc7d7b830ee1 trimmed the platform_device parameter from all of the
suspend functions, but it also accidentally removed it from the resume
function in the Blackfin I2S driver.  So restore it.

Subject: HID: consolidate connect and disconnect into core code

HID core registers input, hidraw and hiddev devices, but leaves
unregistering it up to the individual driver, which is not really nice.
Let's move all the logic to the core.

Subject: PCI ASPM: support L1 only

The definition of the ASPM support field in the Link Capabilities
Register had been changed by the "ASPM optionality ECN" as follows:

<Before>
	00b	Reserved
	01b	L0s Supported
	10b	Reserved
	11b	L0s and L1 Supported

<After>
	00b	No ASPM Support
	01b	L0s Supported
	10b	L1 Supported
	11b	L0s and L1 Supported

Current linux ASPM driver doesn't enable ASPM if the support field is
00b or 10b. So there is no impact about 00b. But current linux ASPM
driver doesn't enable L1 if the support field is 10b. With this patch,
10b (L1 support) is handled properly.

Subject: PCI: pciehp: remove num_slots field

Since PCIe downstream port has only one slot at most, we don't need
num_slots field in struct controller. Note that struct controller
itself doesn't exist if PCIe downstream port has no slot.

The hp_slot field is to identify the slot under the same
controller. But, since PCIe downstream port has only one slot at most,
it is meaningless and we don't need it.

Subject: PCI: pciehp: remove pci_dev field

Since we have a pointer to pcie_device in struct controller, we don't
need a pointer to pci_dev.

routines. But, it is meaningless because no hotplug controller driver
follows this framework.

Subject: MAINTAINTERS: remove hotplug driver entries

So Kristen stops getting PCI hotplug related stuff; the maintainer
switch actually happened awhile ago, but the entries were never purged.

Subject: Btrfs: improve async block group caching

This patch gets rid of two limitations of async block group caching.
The old code delays handling pinned extents when block group is in
caching. To allocate logged file extents, the old code need wait
until block group is fully cached. To get rid of the limitations,
This patch introduces a data structure to track the progress of
caching. Base on the caching progress, we know which extents should
be added to the free space cache when handling the pinned extents.
The logged file extents are also handled in a similar way.

This patch also changes how pinned extents are tracked. The old
code uses one tree to track pinned extents, and copy the pinned
extents tree at transaction commit time. This patch makes it use
two trees to track pinned extents. One tree for extents that are
pinned in the running transaction, one tree for extents that can
be unpinned. At transaction commit time, we swap the two trees.

Subject: perf_counter: Do not throttle single swcounter events

We can have swcounter events that contribute more than a single
count per event, when used with a non-zero period, those can
generate multiple events, which is when we need throttling.

However, swcounter that contribute only a single count per event
can only come as fast as we can run code, hence don't throttle
them.

Subject: perf_counter: Allow for a wakeup watermark

Currently we wake the mmap() consumer once every PAGE_SIZE of data
and/or once event wakeup_events when specified.

For high speed sampling this results in too many wakeups wrt. the
buffer size, hence change this.

We move the default wakeup limit to 1/4-th the buffer size, and
provide for means to manually specify this limit.

I noticed that perf-record continues profiling itself after the

This can cause a _lot_ of overhead with --all recording - we keep

Subject: drm/i915: fix opregion backlight chip detect and range

BLC_PWM_CTL2 is for 965+ only, so add device model check for
legacy backlight control.

For native backlight control, it maps the backlight value (0~255)
in opregion ASLE[BCLP] to backlight duty cycle (0~max_backlight)
and set into control register.

It also add support for IGD device, which follows opregion spec.

Subject: drm/i915: Check whether chip is wedged in i915_wait_request()

i915_wait_request() only checks mm.wedged after it interacts with the
hardware, generally causing the driver to lock up waiting for a wedged
chip. Make sure we check mm.wedged as the first thing we do.

Subject: drm/i915: make i915_seqno_passed non-static

We'll need it in i915_irq.c for checking whether there are outstanding
requests. Also, the function really ought to return a bool, not an int.

Subject: drm/i915: Add hangcheck timer

We set a periodic timer to check on the GPU, resetting it every time a
batch is completed. If the timer elapses, we check acthd. If acthd
hasn't changed in two timer periods, we assume the chip is wedged.

This is implemented in such a way that it leaves the option open to
employ adaptive timer intervals in the future. One could wait until
several timer periods have elapsed before declaring the chip dead. If
the chip comes back after several periods but before the "dead"
threshold, the timer interval or dead threshold could be raised.

It is important to note that while checking for active requests, we need
to account for the fact that requests are removed from the list (i.e.
retired) in a deferred work queue handler. This means that merely
checking for an empty request_list is insufficient; the list could be
non-empty yet the GPU still idle, causing the hangcheck timer to
incorrectly mark the GPU as wedged (it took me a while to figure that
out---sigh...)

Subject: drm/i915: Make dev_priv->mm.wedged an atomic_t

There is a very real possibility that multiple CPUs will notice that the
GPU is wedged. This introduces all sorts of potential race conditions.
Make the wedged flag atomic to mitigate this risk.

Subject: drm/i915: fix suspend/resume breakage in lid notifier

We now unconditionally restore the mode at lid open time since some
platforms turn off the panel, pipes or other display elements when the
lid is closed.  There's a problem with doing this at resume time
however.

At resume time, we'll get a lid event, but restoring the mode at that
time may not be safe (e.g. if we get the lid event before global state
has been restored), so check the suspended state and make sure our
restore is locked against other mode updates.

Subject: drm/i915: fix startup hang on some non-mobile platforms

Due to a bogus FBC support check and failing to check for FBC support
in the right places, mode setting on non-mobile platforms could fail
and hang in the FBC disable routine.  Fix it up.

This fix highlights the need for cleanups in this area (function
pointers and better feature support checks).  Patches for that to
follow.

Subject: drm/i915: Add ioctl to set 'purgeability' of objects

Similar to the madvise() concept, the application may wish to mark some
data as volatile. That is in the event of memory pressure the kernel is
free to discard such buffers safe in the knowledge that the application
can recreate them on demand, and is simply using these as a cache.

Subject: drm/i915: Improve behaviour under memory pressure

Due to the necessity of having to take the struct_mutex, the i915
shrinker can not free the inactive lists if we fail to allocate memory
whilst processing a batch buffer, triggering an OOM and an ENOMEM that
is reported back to userspace. In order to fare better under such
circumstances we need to manually retry a failed allocation after
evicting inactive buffers.

To do so involves 3 steps:
1. Marking the backing shm pages as NORETRY.
2. Updating the get_pages() callers to evict something on failure and then
   retry.
3. Revamping the evict something logic to be smarter about the required
   buffer size and prefer to use volatile or clean inactive pages.

Subject: drm/i915: prevent FIFO calculation overflows on 32 bits with high
 dotclocks

A very high dotclock (e.g. 229500kHz as reported by Anton) can cause
the entries_required variable to overflow, potentially leading to a
FIFO watermark value that's too low to support the given mode.  Split
the division across the calculation to avoid this.

Subject: rcu: Need to update rnp->gpnum if preemptable RCU is to be reliable

Without this patch, tasks preempted in RCU read-side critical
sections can fail to block the grace period, given that
rnp->gpnum is used to determine which rnp->blocked_tasks[]
element the preempted task is enqueued on.

Before the patch, rnp->gpnum is always zero, so preempted tasks
are always enqueued on rnp->blocked_tasks[0], which is correct
only when the current CPU has not checked into the current
grace period and the grace-period number is even, or,
similarly, if the current CPU -has- checked into the current
grace period and the grace-period number is odd.

Subject: rcu: Initialize multi-level RCU grace periods holding locks

Prior implementations initialized the root and any internal
nodes without holding locks, then initialized the leaves
holding locks.

This is a false economy, as the leaf nodes will usually greatly
outnumber the root and internal nodes.  Acquiring locks on all
nodes is conceptually much simpler as well.

Subject: rcu: Kconfig help needs to say that TREE_PREEMPT_RCU scales down

To quote Valdis:

    This leaves somebody who has a laptop wondering which
    choice is best for a system with only one or two cores that
    has CONFIG_PREEMPT defined. One choice says it scales down
    nicely, the other explicitly has a 'depends on PREEMPT'
    attached to it...

So add "scales down nicely" to TREE_PREEMPT_RCU to match that of
TREE_RCU.

Subject: rcu: Simplify rcu_read_unlock_special() quiescent-state accounting

The earlier approach required two scheduling-clock ticks to note an
preemptable-RCU quiescent state in the situation in which the
scheduling-clock interrupt is unlucky enough to always interrupt an
RCU read-side critical section.

With this change, the quiescent state is instead noted by the
outermost rcu_read_unlock() immediately following the first
scheduling-clock tick, or, alternatively, by the first subsequent
context switch.  Therefore, this change also speeds up grace
periods.

Subject: rcu: Fix synchronize_rcu() for TREE_PREEMPT_RCU

The redirection of synchronize_sched() to synchronize_rcu() was
appropriate for TREE_RCU, but not for TREE_PREEMPT_RCU.

Fix this by creating an underlying synchronize_sched().  TREE_RCU
then redirects synchronize_rcu() to synchronize_sched(), while
TREE_PREEMPT_RCU has its own version of synchronize_rcu().

Subject: drm/i915: correct FBC update when pipe base update occurs

We usually don't have an SAREA, and we always want to update the FBC
status anyway, so move the update up above the various master/sarea
checks.

Subject: drm: fix drm_fb_helper handling of kernel crtcs

The drm_fb_helper shouldn't mess with CRTCs that aren't enabled or in
its initial config. Ideally it shouldn't even include CRTCs in its
initial config if they're not in use, but my old fix for that no longer
works.  At any rate, this fixes a real bug I was seeing where after a
console blank, both pipes would come back on, even though only one had
been enabled before that.  Since the other pipe had a bogus config,
this led to some screen corruption.

Subject: drm/radeon: avivo chips have no separate int bit for display

display interrupts are not enabled via this register, the
DISPLAY_INT bit is a status only to show that other regs
need to be read.

Subject: tracing: Allocate the ftrace event profile buffer dynamically

Currently the trace event profile buffer is allocated in the stack. But
this may be too much for the stack, as the events can have large
statically defined field size and can also grow with dynamic arrays.

Allocate two per cpu buffer for all profiled events. The first cpu
buffer is used to host every non-nmi context traces. It is protected
by disabling the interrupts while writing and committing the trace.

The second buffer is reserved for nmi. So that there is no race between
them and the first buffer.

The whole write/commit section is rcu protected because we release
these buffers while deactivating the last profiling trace event.

v2: Move the buffers from trace_event to be global, as pointed by
    Steven Rostedt.

v3: Fix the syscall events to handle the profiling buffer races
    by disabling interrupts, now that the buffers are globals.

Subject: drm/radeon/kms: reprogram format in set base.

This should in theory fix the problem with a mode set being required
for adjusting the color depth.

This also adds in the necessary bits to the format tables for
8-bit, though it doesn't work yet.

Subject: drm/r600/kms: fixup number of loops per blit calculation.

Some people were seeing
*ERROR* radeon: writting more dword to ring than expected
after certain blits, the loops calculation didn't take
into account that we do a separate blit for the remainder
after doing the aligned blits.

Subject: drm/radeon/kms: don't fail if we fail to init GPU acceleration

Userspace can query if acceleration is working or not true get
info ioctl and could fallback to software if for some reason
kernel failed to initialize KMS. This should allow to give a
working KMS setup in all case (even with non functionning accel).

From 445282db9e815e7f5e82761c3c971dc9ea988d85 Mon Sep 17 00:00:00 2001
From: Dave Airlie <airlied@redhat.com>
Date: Wed, 9 Sep 2009 17:40:54 +1000
Subject: drm/radeon/kms: add initial connector properties

This adds:
coherent mode: TMDS coherent mode for atom cards.
scaling mode: LVDS scaler mode
load detect: DAC load detection, DVI-I, VGA, TV
tmds pll: legacy TMDS pll selection
tv standard: TV standard selection.

for later: other TV ones? dvi subconnector selection using std prop

[contains fixes pointed out on dri-devel for atom bios mixups
 by Michel]

Subject: drm/radeon/kms: Move radeon_get_clock_info() call out of

MIME-Version: 1.0

Someone on IRC reported problems after commit
95a8f1bf4f48b434c9f839ab5a0773f66b39d7c6 ('drm/radeon/kms: Move
radeon_clocks_init() call back after getting VRAM info.'). And indeed, at least
some ASIC vram_info hooks use the clock info obtained by
radeon_get_clock_info(). So, move that call out of radeon_clocks_init(), ahead
of the radeon_vram_info() call.

Subject: drm/radeon/kms: disable VGA rendering engine before taking over VRAM

Before we use any of VRAM, we need to disable the VGA rendering
engine, this render text mode into a graphical framebuffer
for scanout, however it does this on vblank, and can end up
overwriting the GART table and r600 shader objects.

Subject: drm/radeon/kms: move around new init path code to avoid posting at
 init

We really don't want to post the card at init, it takes a relatively
long time and isn't required, so split the resume path into
a startup path called by both init/resume and separate resume
entry point to do posting.

Subject: Input: libps2 - additional locking for i8042 ports

The serio ports on i8042 are not completely isolated; while we provide
enough locking to ensure proper serialization when accessing control
and data registers AUX and KBD ports can still have an effect on each
other on PS/2 protocol level. The most prominent effect is that
issuing a command for the device connected to one port may cause
abort of the command currently executing by the device connected to
another port.

Since i8042 nor serio subsystem are not aware of the details of the
PS/2 protocol (length of the commands and their replies and so on) the
locking should be done on libps2 level by adding special handling when
we see that we are dealing with serio port on i8042.

Subject: Input: add touchscreen driver for MELFAS MCS-5000 controller

The MELPAS MCS-5000 is the touchscreen controller. The overview of this
controller can see at the following website:

http://www.melfas.com/product/product01.asp?k_r=eng_

This driver is tested on s3c6410 NCP board and supports only the i2c
interface.

Subject: perf sched: Add --input=file option to builtin-sched.c

perf sched record passes unparsed args on to perf record, so
specifying an output file via perf sched record -o FILE (cmd) just
works.  Ergo, provide an option to specify input file as well.

Also add the missing 'map' command to help.

Subject: x86: SGI UV: Map MMIO-High memory range

UV depends on the MMRHI space being identity mapped. The patch:

	x86: Make 64-bit efi_ioremap use ioremap on MMIO regions

changed this to make efi regions at a different address using
ioremap. Add the identity mapping to uv_system_init.

( Note this code was previously present but was deleted when BIOS
  added the ranges to the EFI map - previous efi code identify
  mapped the ranges. )

Subject: sunrpc/cache: use list_del_init for the list_head entries in
 cache_deferred_req

Using list_del_init is generally safer than list_del, and it will
allow us, in a subsequent patch, to see if an entry has already been
processed or not.

Subject: x86/PCI: default pcibus cpumask to all cpus if it lacks affinity

The early initialization of the pci bus to node mapping leaves all busses
with a node id of -1 if it lacks memory affinity.  Thus, cpumask_of_pcibus
must return all online cpus for such busses.

Subject: x86: fix fragile computation of vsyscall address

Previously, the address of the vsyscall page (VSYSCALL_PHYS_ADDR,
VSYSCALL_VIRT_ADDR) was computed by arithmetic on the address of the
last section.  This leads to bugs when new sections are inserted, such
as the one fixed by commit d312ceda567ab91acd756cde95ac5fbc6b40ed40.
Let's compute it from the current address instead.

Subject: x86: convert compressed loader to use __HEAD and HEAD_TEXT macros.

This has the consequence of changing the section name use for head
code from ".text.head" to ".head.text".

Linus suggested that we merge the ".text.head" section with ".text"
(presumably while preserving the fact that the head code starts at 0).
When I tried this it caused the kernel to not boot.

This has the consequence of changing the section name use for head
code from ".text.head" to ".head.text".  It also eliminates the
".text.head" output section (instead placing head code at the start of
the .text output section), which should be harmless.

This patch only changes the sections in the actual kernel, not those
in the compressed boot loader.

Subject: x86: Use section .data.page_aligned for the idt_table.

The .data.idt section is just squashed into the .data.page_aligned
output section by the linker script anyway, so it might as well be in
the .data.page_aligned section.

This eliminates all references to .data.idt on x86.

From 5622f295b53fb60dbf9bed3e2c89d182490a8b7f Mon Sep 17 00:00:00 2001
From: Markus Metzger <markus.t.metzger@intel.com>
Date: Tue, 15 Sep 2009 13:00:23 +0200
Subject: x86, perf_counter, bts: Optimize BTS overflow handling

Draining the BTS buffer on a buffer overflow interrupt takes too
long resulting in a kernel lockup when tracing the kernel.

Restructure perf_counter sampling into sample creation and sample
output.

Prepare a single reference sample for BTS sampling and update the
from and to address fields when draining the BTS buffer. Drain the
entire BTS buffer between a single perf_output_begin() /
perf_output_end() pair.

Subject: sched_clock: Make it NMI safe

Arjan complained about the suckyness of TSC on modern machines, and
asked if we could do something about that for PERF_SAMPLE_TIME.

Make cpu_clock() NMI safe by removing the spinlock and using
cmpxchg. This also makes it smaller and more robust.

Affects architectures that use HAVE_UNSTABLE_SCHED_CLOCK, i.e. IA64
and x86.

- 	             Using the Linux Kernel Markers
-
-			    Mathieu Desnoyers
-
-
-This document introduces Linux Kernel Markers and their use. It provides
-examples of how to insert markers in the kernel and connect probe functions to
-them and provides some examples of probe functions.
-
-
-* Purpose of markers
-
-A marker placed in code provides a hook to call a function (probe) that you can
-provide at runtime. A marker can be "on" (a probe is connected to it) or "off"
-(no probe is attached). When a marker is "off" it has no effect, except for
-adding a tiny time penalty (checking a condition for a branch) and space
-penalty (adding a few bytes for the function call at the end of the
-instrumented function and adds a data structure in a separate section).  When a
-marker is "on", the function you provide is called each time the marker is
-executed, in the execution context of the caller. When the function provided
-ends its execution, it returns to the caller (continuing from the marker site).
-
-You can put markers at important locations in the code. Markers are
-lightweight hooks that can pass an arbitrary number of parameters,
-described in a printk-like format string, to the attached probe function.
-
-They can be used for tracing and performance accounting.
-
-
-* Usage
-
-In order to use the macro trace_mark, you should include linux/marker.h.
-
-#include <linux/marker.h>
-
-And,
-
-trace_mark(subsystem_event, "myint %d mystring %s", someint, somestring);
-Where :
-- subsystem_event is an identifier unique to your event
-    - subsystem is the name of your subsystem.
-    - event is the name of the event to mark.
-- "myint %d mystring %s" is the formatted string for the serializer. "myint" and
-  "mystring" are repectively the field names associated with the first and
-  second parameter.
-- someint is an integer.
-- somestring is a char pointer.
-
-Connecting a function (probe) to a marker is done by providing a probe (function
-to call) for the specific marker through marker_probe_register() and can be
-activated by calling marker_arm(). Marker deactivation can be done by calling
-marker_disarm() as many times as marker_arm() has been called. Removing a probe
-is done through marker_probe_unregister(); it will disarm the probe.
-
-marker_synchronize_unregister() must be called between probe unregistration and
-the first occurrence of
-- the end of module exit function,
-  to make sure there is no caller left using the probe;
-- the free of any resource used by the probes,
-  to make sure the probes wont be accessing invalid data.
-This, and the fact that preemption is disabled around the probe call, make sure
-that probe removal and module unload are safe. See the "Probe example" section
-below for a sample probe module.
-
-The marker mechanism supports inserting multiple instances of the same marker.
-Markers can be put in inline functions, inlined static functions, and
-unrolled loops as well as regular functions.
-
-The naming scheme "subsystem_event" is suggested here as a convention intended
-to limit collisions. Marker names are global to the kernel: they are considered
-as being the same whether they are in the core kernel image or in modules.
-Conflicting format strings for markers with the same name will cause the markers
-to be detected to have a different format string not to be armed and will output
-a printk warning which identifies the inconsistency:
-
-"Format mismatch for probe probe_name (format), marker (format)"
-
-Another way to use markers is to simply define the marker without generating any
-function call to actually call into the marker. This is useful in combination
-with tracepoint probes in a scheme like this :
-
-void probe_tracepoint_name(unsigned int arg1, struct task_struct *tsk);
-
-DEFINE_MARKER_TP(marker_eventname, tracepoint_name, probe_tracepoint_name,
-	"arg1 %u pid %d");
-
-notrace void probe_tracepoint_name(unsigned int arg1, struct task_struct *tsk)
-{
-	struct marker *marker = &GET_MARKER(kernel_irq_entry);
-	/* write data to trace buffers ... */
-}
-
-* Probe / marker example
-
-See the example provided in samples/markers/src
-
-Compile them with your kernel.
-
-Run, as root :
-modprobe marker-example (insmod order is not important)
-modprobe probe-example
-cat /proc/marker-example (returns an expected error)
-rmmod marker-example probe-example
-dmesg

Subject: Btrfs: properly honor wbc->nr_to_write changes

When btrfs fills a delayed allocation, it tries to increase
the wbc nr_to_write to cover a big part of allocation.  The
theory is that we're doing contiguous IO and writing a few
more blocks will save seeks overall at a very low cost.

The problem is that extent_write_cache_pages could ignore
the new higher nr_to_write if nr_to_write had already gone
down to zero.  We fix that by rechecking the nr_to_write
for every page that is processed in the pagevec.

This updates the math around bumping the nr_to_write value
to make sure we don't leave a tiny amount of IO hanging
around for the very end of a new extent.

Subject: Btrfs: search for an allocation hint while filling file COW

The allocator has some nice knobs for sending hints about where
to try and allocate new blocks, but when we're doing file allocations
we're not sending any hint at all.

This commit adds a simple extent map search to see if we can
quickly and easily find a hint for the allocator.

Subject: i2c-taos-evm: Switch echo off to improve performance

When echo is on, we waste time reading back our orders. Switching echo
off makes performance much better: SMBus byte data transactions are 47%
faster and byte transactions are 24% faster.

Subject: i2c/tsl2550: Use combined SMBus transactions

Make the I/O faster, mainly by using combined SMBus transactions when
possible. While the TSL2550 datasheet doesn't say the device supports
them, they seem to work just fine in practice, and a combined
transaction is faster than two simple transactions in many cases and
always more reliable.

A side effect is to suppress the delays between SMBus writes and
reads. The datasheet doesn't say they are needed and things work just
fine for me without them.

I also couldn't see any reason for the delay between reading the two
channels. Nor for the loop to get a reading in the first place. The
400 ms delay between samples only matters at chip power-up, after that
the chip always hold the previously sampled value so we never get to
wait.

All these changes make reading the lux value much faster and cheaper.

Subject: i2c: Provide compatibility links for i2c adapters

Some user-space applications may be relying on i2c adapters showing up
as class devices in sysfs. Provide compatibility links for them for
the time being. We will remove them after a long transition period.

-About the PCF8575 chip and the pcf8575 kernel driver
-====================================================
-
-The PCF8575 chip is produced by the following manufacturers:
-
-  * Philips NXP
-    http://www.nxp.com/#/pip/cb=[type=product,path=50807/41735/41850,final=PCF8575_3]|pip=[pip=PCF8575_3][0]
-
-  * Texas Instruments
-    http://focus.ti.com/docs/prod/folders/print/pcf8575.html
-
-
-Some vendors sell small PCB's with the PCF8575 mounted on it. You can connect
-such a board to a Linux host via e.g. an USB to I2C interface. Examples of
-PCB boards with a PCF8575:
-
-  * SFE Breakout Board for PCF8575 I2C Expander by RobotShop
-    http://www.robotshop.ca/home/products/robot-parts/electronics/adapters-converters/sfe-pcf8575-i2c-expander-board.html
-
-  * Breakout Board for PCF8575 I2C Expander by Spark Fun Electronics
-    http://www.sparkfun.com/commerce/product_info.php?products_id=8130
-
-
-Description
------------
-The PCF8575 chip is a 16-bit I/O expander for the I2C bus. Up to eight of
-these chips can be connected to the same I2C bus. You can find this
-chip on some custom designed hardware, but you won't find it on PC
-motherboards.
-
-The PCF8575 chip consists of a 16-bit quasi-bidirectional port and an I2C-bus
-interface. Each of the sixteen I/O's can be independently used as an input or
-an output. To set up an I/O pin as an input, you have to write a 1 to the
-corresponding output.
-
-For more information please see the datasheet.
-
-
-Detection
----------
-
-There is no method known to detect whether a chip on a given I2C address is
-a PCF8575 or whether it is any other I2C device, so you have to pass the I2C
-bus and address of the installed PCF8575 devices explicitly to the driver at
-load time via the force=... parameter.
-
-/sys interface
---------------
-
-For each address on which a PCF8575 chip was found or forced the following
-files will be created under /sys:
-* /sys/bus/i2c/devices/<bus>-<address>/read
-* /sys/bus/i2c/devices/<bus>-<address>/write
-where bus is the I2C bus number (0, 1, ...) and address is the four-digit
-hexadecimal representation of the 7-bit I2C address of the PCF8575
-(0020 .. 0027).
-
-The read file is read-only. Reading it will trigger an I2C read and will hence
-report the current input state for the pins configured as inputs, and the
-current output value for the pins configured as outputs.
-
-The write file is read-write. Writing a value to it will configure all pins
-as output for which the corresponding bit is zero. Reading the write file will
-return the value last written, or -EAGAIN if no value has yet been written to
-the write file.
-
-On module initialization the configuration of the chip is not changed -- the
-chip is left in the state it was already configured in through either power-up
-or through previous I2C write actions.

-Kernel driver pca9539
-=====================
-
-NOTE: this driver is deprecated and will be dropped soon, use
-drivers/gpio/pca9539.c instead.
-
-Supported chips:
-  * Philips PCA9539
-    Prefix: 'pca9539'
-    Addresses scanned: none
-    Datasheet:
-        http://www.semiconductors.philips.com/acrobat/datasheets/PCA9539_2.pdf
-
-Author: Ben Gardner <bgardner@wabtec.com>
-
-
-Description
------------
-
-The Philips PCA9539 is a 16 bit low power I/O device.
-All 16 lines can be individually configured as an input or output.
-The input sense can also be inverted.
-The 16 lines are split between two bytes.
-
-
-Detection
----------
-
-The PCA9539 is difficult to detect and not commonly found in PC machines,
-so you have to pass the I2C bus and address of the installed PCA9539
-devices explicitly to the driver at load time via the force=... parameter.
-
-
-Sysfs entries
--------------
-
-Each is a byte that maps to the 8 I/O bits.
-A '0' suffix is for bits 0-7, while '1' is for bits 8-15.
-
-input[01]     - read the current value
-output[01]    - sets the output value
-direction[01] - direction of each bit: 1=input, 0=output
-invert[01]    - toggle the input bit sense
-
-input reads the actual state of the line and is always available.
-The direction defaults to input for all channels.
-
-
-General Remarks
----------------
-
-Note that each output, direction, and invert entry controls 8 lines.
-You should use the read, modify, write sequence.
-For example. to set output bit 0 of 1.
-  val=$(cat output0)
-  val=$(( $val | 1 ))
-  echo $val > output0

From e7c5c49ecdac6dc5a6b67a27838b1b562eeec1b9 Mon Sep 17 00:00:00 2001
From: Wolfram Sang <w.sang@pengutronix.de>
Date: Fri, 18 Sep 2009 22:45:49 +0200
Subject: i2c/chips: Remove deprecated pcf8574 driver

The pcf8574 driver in drivers/i2c/chips which just exports its register to
sysfs is superseded by drivers/gpio/pcf857x.c which properly uses the gpiolib.
As this driver has been deprecated for more than a year, finally remove it.

-Description
------------
-The PCF8574(A) is an 8-bit I/O expander for the I2C bus produced by Philips
-Semiconductors. It is designed to provide a byte I2C interface to up to 16
-separate devices (8 x PCF8574 and 8 x PCF8574A).
-
-This device consists of a quasi-bidirectional port. Each of the eight I/Os
-can be independently used as an input or output. To setup an I/O as an
-input, you have to write a 1 to the corresponding output.
-
-For more informations see the datasheet.
-
-
-Accessing PCF8574(A) via /sys interface
--------------------------------------
-
-The PCF8574(A) is plainly impossible to detect ! Stupid chip.
-So, you have to pass the I2C bus and address of the installed PCF857A
-and PCF8574A devices explicitly to the driver at load time via the
-force=... parameter.
-
-On detection (i.e. insmod, modprobe et al.), directories are being
-created for each detected PCF8574(A):
-
-/sys/bus/i2c/devices/<0>-<1>/
-where <0> is the bus the chip was detected on (e. g. i2c-0)
-and <1> the chip address ([20..27] or [38..3f]):
-
-(example: /sys/bus/i2c/devices/1-0020/)
-
-Inside these directories, there are two files each:
-read and write (and one file with chip name).
-
-The read file is read-only. Reading gives you the current I/O input
-if the corresponding output is set as 1, otherwise the current output
-value, that is to say 0.
-
-The write file is read/write. Writing a value outputs it on the I/O
-port. Reading returns the last written value. As it is not possible
-to read this value from the chip, you need to write at least once to
-this file before you can read back from it.

request_mem_region should be used when ioremap is used subsequently.
release_region is then correspondingly replaced by release_mem_region.

Subject: i2c: Clearly mark ACPI drivers as such

Now that we have ACPI-based SMBus controller drivers, and we will start
telling users to use them instead of native drivers when I/O resources
conflict, I think it would be good to clearly mark ACPI drivers as such
in Kconfig.

This is exactly the same as we just did for hwmon drivers.

Subject: sunrpc/cache: avoid variable over-loading in cache_defer_req

In cache_defer_req, 'dreq' is used for two significantly different
values that happen to be of the same type.

This is both confusing, and makes it hard to extend the range of one of
the values as we will in the next patch.
So introduce 'discard' to take one of the values.

Subject: ARM: 5704/1: U300 sched_clock implementation v2

This adds the long debated sched_clock() override for the weak
in-kernel jiffybased sched_clock(). The implementation is more or
less identical to the one used in arch/arm/plat-omap/common.c
and at last attempt to merge this the merge was postponed at the
request of Peter Zijlstra due to pending discussions regarding
generalized clocksource-based sched_clock() implementations by
adding a flag to the clocksource. However that discussion ended
up with the generic code needing to be rewritten and Paul Mundt
see no reason not to proceed with this for the time being as it
can be easily converted once the generic code is in place.

Subject: ARM: 5678/1: SSP/SPI PL022 polarity terminology fix

The definition of the SPI clock phase for the Motorola mode of
the PL022 driver was incorrect: the spec had been interpreted as
data being recieved on rising or falling edge of the clocks while
the correct interpretation is that data can be recieved on the
first or second edge transition, falling or rising depending on
the polarity setting.

Subject: Clear the exclusive monitor when returning from an exception

The patch adds a CLREX or dummy STREX to the exception return path. This
is needed because several atomic/locking operations use a pair of
LDREX/STREXEQ and the EQ condition may not always be satisfied. This
would leave the exclusive monitor status set and may cause problems with
atomic/locking operations in the interrupted code.

With this patch, the atomic_set() operation can be a simple STR
instruction (on SMP systems, the global exclusive monitor is cleared by
STR anyway). Clearing the exclusive monitor during context switch is no
longer needed as this is handled by the exception return path anyway.

Subject: Thumb-2: Correctly handle undefined instructions in the kernel

VFP instructions in the kernel may trigger undefined exceptions if VFP
hardware is not present. This patch corrects the loading of such Thumb-2
instructions. It also marks the "no_fp" label as a function so that the
linker generate a Thumb address.

Subject: drm/i915: Check that the relocation points to within the target

Eric noted a potential concern with the low bits not being strictly used
as part of the absolute offset (instead part of the command stream to the
GPU), but in practice that should not be an issue.

Subject: drm/i915: Skip the sanity checks if the current relocation is valid

If the presumed_offset as feed to userspace and returned to the kernel
from a previous execbuffer is still valid, then we do not need to rewrite
the relocation entry and may skip the offset sanity checks.

From 1a9fc855643f8770c92ba99fad5f209358c6030d Mon Sep 17 00:00:00 2001
From: Mauro Carvalho Chehab <mchehab@redhat.com>
Date: Sun, 13 Sep 2009 11:30:11 -0300
Subject: V4L/DVB (12733): cx25821: some CodingStyle fixes

The original driver were generated with some dos editor, and used their
own coding style.

This patch does some automatic CodingStyle fixes, by running dos2unix
and Lindent tools.

More work still needs to be done for it to use upstream CodingStyle.

Subject: V4L/DVB (12734): cx25821: Fix some compilation troubles

Lindent caused some compilation breakages. There were also others
related to some other changes at kernel KABI.

There's still one missing warning fix against 2.6.30:

/home/v4l/cx25821/v4l/cx25821-alsa.c: In function 'cx25821_audio_initdev':
/home/v4l/cx25821/v4l/cx25821-alsa.c:706: warning: 'snd_card_new' is deprecated (declared at include/sound/core.h:306)

Subject: V4L/DVB (12741): em28xx: make video isoc stream work when VBI is
 enabled

Add code enabling the VBI registers for variants of the em28xx chip that
support VBI, and make sure the isoc streaming code continues to work for
the video component of the stream (note the video and vbi data arrive
intermixed on the same isoc pipe).

Note that this version just drops the actual VBI data onto the floor as
opposed to processing it.  The "#ifdef 0" tags are for the videobuf code that
appears in the next patch in this series.

We created a separate version of the isoc_copy version for parsing the version
of the stream that includes VBI data.  In theory, they might be able to be
merged at some point in the future, but the initial goal is to ensure that we
do not cause any regressions with devices that do not have VBI support.

This work was sponsored by EyeMagnet Limited.

Subject: V4L/DVB (12742): em28xx: add raw VBI support for NTSC

Add support for raw VBI capture for the em28xx bridge, currently only for
NTSC.  Support for PAL capture to follow shortly (including the removal of
numerous hard-coded NTSC-specific sizes for capture buffers, etc).

Note that the code currently changes the default current norm from PAL to
NTSC (so that zvbi-ntsc-cc works properly).  The default norm really should
be moved into a board-level parameter.

This work was sponsored by EyeMagnet Limited.

Subject: V4L/DVB (12744): em28xx: restructure fh/dev locking to handle both
 video and vbi

The current locking infrastructure didn't support having multiple fds accessing
the device (such as video and vbi).  Rework the locking infrastructure,
borrowing the design from cx88.

This work was sponsored by EyeMagnet Limited.

Change the code so we only claim to support VBI if the underlying chipset
actually has the support.

Subject: V4L/DVB (12748): em28xx: implement g_std v4l call

We need to implement the g_std call, or else the default norm always gets
returned, which breaks VBI capturing if you had changed the standard to NTSC
using s_std.

I had temporarily changed the default norm to NTSC so that zvbi-ntsc-cc
wouldn't choke, so now that we are returning the correct value, switch it back
to PAL as the default.

Subject: V4L/DVB (12761): DocBook: add media API specs

The V4L and DVB API's are there for a long time. however, up to now,
no efforts were done to merge them to kernel DocBook.

This patch adds the current versions of the specs as an unique compendium.

+<para>This system call opens a named audio device (e.g. /dev/dvb/adapter0/audio0)
+ for subsequent use. When an open() call has succeeded, the device will be ready
+ for use. The significance of blocking or non-blocking mode is described in the
+ documentation for functions where there is a difference. It does not affect the
+ semantics of the open() call itself. A device opened in blocking mode can later
+ be put into non-blocking mode (and vice versa) using the F_SETFL command
+ of the fcntl system call. This is a standard system call, documented in the Linux
+ manual page for fcntl. Only one user can open the Audio Device in O_RDWR
+ mode. All other attempts to open the device in this mode will fail, and an error
+ code will be returned. If the Audio Device is opened in O_RDONLY mode, the
+ only ioctl call that can be used is AUDIO_GET_STATUS. All other call will

+<para>This system call opens a named frontend device (/dev/dvb/adapter0/frontend0)
+ for subsequent use. Usually the first thing to do after a successful open is to
+ find out the frontend type with FE_GET_INFO.</para>
+<para>The device can be opened in read-only mode, which only allows monitoring of
+ device status and statistics, or read/write mode, which allows any kind of use
+ (e.g. performing tuning operations.)
+</para>
+<para>In a system with multiple front-ends, it is usually the case that multiple devices
+ cannot be open in read/write mode simultaneously. As long as a front-end
+ device is opened in read/write mode, other open() calls in read/write mode will
+ either fail or block, depending on whether non-blocking or blocking mode was
+ specified. A front-end device opened in blocking mode can later be put into
+ non-blocking mode (and vice versa) using the F_SETFL command of the fcntl
+ system call. This is a standard system call, documented in the Linux manual
+ page for fcntl. When an open() call has succeeded, the device will be ready
+ for use in the specified mode. This implies that the corresponding hardware is
+ powered up, and that other front-ends may have been powered down to make
+ that possible.</para>

+<title>History</title>
+
+<para>The first API for DVB cards we used at Convergence in late 1999
+was an extension of the Video4Linux API which was primarily developed
+for frame grabber cards. As such it was not really well suited to be
+used for DVB cards and their new features like recording MPEG streams
+and filtering several section and PES data streams at the same time.
+</para>
+
+<para>In early 2000, we were approached by Nokia with a proposal for a
+new standard Linux DVB API. As a commitment to the development of
+terminals based on open standards, Nokia and Convergence made it
+available to all Linux developers and published it on <emphasis
+role="tt">http://www.linuxtv.org/</emphasis> in September 2000.
+Convergence is the maintainer of the Linux DVB API. Together with the
+LinuxTV community (i.e. you, the reader of this document), the Linux DVB
+API will be constantly reviewed and improved. With the Linux driver for
+the Siemens/Hauppauge DVB PCI card Convergence provides a first
+implementation of the Linux DVB API.</para>

+<para>A DVB PCI card or DVB set-top-box (STB) usually consists of the
+following main hardware components: </para>
+
+<itemizedlist>
+ <listitem>
+
+<para>Frontend consisting of tuner and DVB demodulator</para>
+
+<para>Here the raw signal reaches the DVB hardware from a satellite dish
+or antenna or directly from cable. The frontend down-converts and
+demodulates this signal into an MPEG transport stream (TS). In case of a
+satellite frontend, this includes a facility for satellite equipment
+control (SEC), which allows control of LNB polarization, multi feed
+switches or dish rotors.</para>
+
+</listitem>
+ <listitem>
+
+<para>Conditional Access (CA) hardware like CI adapters and smartcard slots
+</para>
+
+<para>The complete TS is passed through the CA hardware. Programs to
+which the user has access (controlled by the smart card) are decoded in
+real time and re-inserted into the TS.</para>
+
+</listitem>
+ <listitem>
+ <para>Demultiplexer which filters the incoming DVB stream</para>
+
+<para>The demultiplexer splits the TS into its components like audio and
+video streams. Besides usually several of such audio and video streams
+it also contains data streams with information about the programs
+offered in this or other streams of the same provider.</para>
+
+</listitem>
+<listitem>
+
+<para>MPEG2 audio and video decoder</para>
+
+<para>The main targets of the demultiplexer are the MPEG2 audio and
+video decoders. After decoding they pass on the uncompressed audio and
+video to the computer screen or (through a PAL/NTSC encoder) to a TV
+set.</para>
+
+
+</listitem>
+</itemizedlist>
+
+<para><xref linkend="stb_components" /> shows a crude schematic of the control and data flow
+between those components.</para>
+
+<para>On a DVB PCI card not all of these have to be present since some
+functionality can be provided by the main CPU of the PC (e.g. MPEG
+picture and sound decoding) or is not needed (e.g. for data-only uses
+like &#8220;internet over satellite&#8221;). Also not every card or STB
+provides conditional access hardware.</para>

+<para>The Linux DVB API lets you control these hardware components
+through currently six Unix-style character devices for video, audio,
+frontend, demux, CA and IP-over-DVB networking. The video and audio
+devices control the MPEG2 decoder hardware, the frontend device the
+tuner and the DVB demodulator. The demux device gives you control over
+the PES and section filters of the hardware. If the hardware does not
+support filtering these filters can be implemented in software. Finally,
+the CA device controls all the conditional access capabilities of the
+hardware. It can depend on the individual security requirements of the
+platform, if and how many of the CA functions are made available to the
+application through this device.</para>

+<para>All devices can be found in the <emphasis role="tt">/dev</emphasis>

+<title>Demux API</title>
+<para>The demux API should be implemented for each demux in the system. It is used to select
+the TS source of a demux and to manage the demux resources. When the demux
+client allocates a resource via the demux API, it receives a pointer to the API of that
+resource.
+</para>
+<para>Each demux receives its TS input from a DVB front-end or from memory, as set via the
+demux API. In a system with more than one front-end, the API can be used to select one of
+the DVB front-ends as a TS source for a demux, unless this is fixed in the HW platform. The
+demux API only controls front-ends regarding their connections with demuxes; the APIs
+used to set the other front-end parameters, such as tuning, are not defined in this
+document.
+</para>
+<para>The functions that implement the abstract interface demux should be defined static or
+module private and registered to the Demux Directory for external access. It is not necessary
+to implement every function in the demux_t struct, however (for example, a demux interface
+might support Section filtering, but not TS or PES filtering). The API client is expected to
+check the value of any function pointer before calling the function: the value of NULL means
+&#8220;function not available&#8221;.
+</para>
+<para>Whenever the functions of the demux API modify shared data, the possibilities of lost
+update and race condition problems should be addressed, e.g. by protecting parts of code with
+mutexes. This is especially important on multi-processor hosts.
+</para>
+<para>Note that functions called from a bottom half context must not sleep, at least in the 2.2.x
+kernels. Even a simple memory allocation can result in a kernel thread being put to sleep if
+swapping is needed. For example, the Linux kernel calls the functions of a network device
+interface from a bottom half context. Thus, if a demux API function is called from network
+device code, the function must not sleep.

+<title>Demux Callback API</title>
+<para>This kernel-space API comprises the callback functions that deliver filtered data to the

+from the demux code.
+</para>
+<para>The function pointers of this abstract interface are not packed into a structure as in the
+other demux APIs, because the callback functions are registered and used independent
+of each other. As an example, it is possible for the API client to provide several
+callback functions for receiving TS packets and no callbacks for PES packets or
+sections.
+</para>
+<para>The functions that implement the callback API need not be re-entrant: when a demux
+driver calls one of these functions, the driver is not allowed to call the function again before
+the original call returns. If a callback is triggered by a hardware interrupt, it is recommended
+to use the Linux &#8220;bottom half&#8221; mechanism or start a tasklet instead of making the callback
+function call directly from a hardware interrupt.

+<title>Section Feed API</title>
+<para>A section feed is a resource consisting of a PID filter and a set of section filters. Using this
+API, the client can set the properties of a section feed and to start/stop filtering. The API is
+defined as an abstract interface of the type dmx_section_feed_t. The functions that implement
+the interface should be defined static or module private. The client can get the handle of
+a section feed API by calling the function allocate_section_feed() in the demux
+API.
+</para>
+<para>On demux platforms that provide section filtering in hardware, the Section Feed API
+implementation provides a software wrapper for the demux hardware. Other platforms may
+support only PID filtering in hardware, requiring that TS packets are converted to sections in
+software. In the latter case the Section Feed API implementation can be a client of the TS
+Feed API.

+<para>When an open() call has succeeded, the device will be ready for use.
+ The significance of blocking or non-blocking mode is described in the
+ documentation for functions where there is a difference. It does not affect the
+ semantics of the open() call itself. A device opened in blocking mode can later
+ be put into non-blocking mode (and vice versa) using the F_SETFL command
+ of the fcntl system call. This is a standard system call, documented in the Linux
+ manual page for fcntl. Only one user can open the Video Device in O_RDWR
+ mode. All other attempts to open the device in this mode will fail, and an
+ error-code will be returned. If the Video Device is opened in O_RDONLY
+ mode, the only ioctl call that can be used is VIDEO_GET_STATUS. All other

+ be used with the device file descriptor to watch for new events. For select(),
+ the file descriptor should be included in the exceptfds argument, and for

+	<para>This document covers the Linux Kernel to Userspace API's used by
+		video and radio straming devices, including video cameras,
+		analog and digital TV receiver cards, AM/FM receiver cards,
+		streaming capture devices.</para>
+	<para>It is divided into three parts.</para>
+	<para>The first part covers radio, capture,
+		cameras and analog TV devices.</para>
+	<para>The second part covers the
+		API used for digital TV and Internet reception via one of the
+		several digital tv standards. While it is called as DVB API,
+		in fact it covers several different video standards including
+		DVB-T, DVB-S, DVB-C and ATSC. The API is currently being updated
+		to documment support also for DVB-S2, ISDB-T and ISDB-S.</para>
+	<para>The third part covers other API's used by all media infrastructure devices</para>
+	<para>For additional information and for the latest development code,
+		see: <ulink url="http://linuxtv.org">http://linuxtv.org</ulink>.</para>
+	<para>For discussing improvements, reporting troubles, sending new drivers, etc, please mail to: <ulink url="http://vger.kernel.org/vger-lists.html#linux-media">Linux Media Mailing List (LMML).</ulink>.</para>

+      <title>Device Naming</title>
+
+      <para>V4L2 drivers are implemented as kernel modules, loaded
+manually by the system administrator or automatically when a device is
+first opened. The driver modules plug into the "videodev" kernel
+module. It provides helper functions and a common application
+interface specified in this document.</para>
+
+      <para>Each driver thus loaded registers one or more device nodes
+with major number 81 and a minor number between 0 and 255. Assigning
+minor numbers to V4L2 devices is entirely up to the system administrator,
+this is primarily intended to solve conflicts between devices.<footnote>
+	  <para>Access permissions are associated with character
+device special files, hence we must ensure device numbers cannot
+change with the module load order. To this end minor numbers are no
+longer automatically assigned by the "videodev" module as in V4L but
+requested by the driver. The defaults will suffice for most people
+unless two drivers compete for the same minor numbers.</para>
+	</footnote> The module options to select minor numbers are named
+after the device special file with a "_nr" suffix. For example "video_nr"
+for <filename>/dev/video</filename> video capture devices. The number is
+an offset to the base minor number associated with the device type.
+<footnote>
+	  <para>In earlier versions of the V4L2 API the module options
+where named after the device special file with a "unit_" prefix, expressing
+the minor number itself, not an offset. Rationale for this change is unknown.
+Lastly the naming and semantics are just a convention among driver writers,
+the point to note is that minor numbers are not supposed to be hardcoded
+into drivers.</para>
+	</footnote> When the driver supports multiple devices of the same
+type more than one minor number can be assigned, separated by commas:
+<informalexample>
+	  <screen>
+&gt; insmod mydriver.o video_nr=0,1 radio_nr=0,1</screen>
+	</informalexample></para>
+
+      <para>In <filename>/etc/modules.conf</filename> this may be
+written as: <informalexample>
+	  <screen>
+alias char-major-81-0 mydriver
+alias char-major-81-1 mydriver
+alias char-major-81-64 mydriver              <co id="alias" />
+options mydriver video_nr=0,1 radio_nr=0,1   <co id="options" />

+recommends the base minor numbers to be used for the various device
+types. Obviously minor numbers must be unique. When the number is
+already in use the <emphasis>offending device</emphasis> will not be
+registered. <!-- Blessed by Linus Torvalds on

+
+      <para>By convention system administrators create various
+character device special files with these major and minor numbers in
+the <filename>/dev</filename> directory. The names recomended for the
+different V4L2 device types are listed in <xref linkend="devices" />.
+</para>
+
+      <para>The creation of character special files (with
+<application>mknod</application>) is a privileged operation and
+devices cannot be opened by major and minor number. That means
+applications cannot <emphasis>reliable</emphasis> scan for loaded or
+installed drivers. The user must enter a device name, or the
+application can try the conventional device names.</para>
+
+      <para>Under the device filesystem (devfs) the minor number
+options are ignored. V4L2 drivers (or by proxy the "videodev" module)
+automatically create the required device files in the
+<filename>/dev/v4l</filename> directory using the conventional device
+names above.</para>
+    </section>
+
+    <section id="related">
+      <title>Related Devices</title>
+
+      <para>Devices can support several related functions. For example
+video capturing, video overlay and VBI capturing are related because
+these functions share, amongst other, the same video input and tuner
+frequency. V4L and earlier versions of V4L2 used the same device name
+and minor number for video capturing and overlay, but different ones
+for VBI. Experience showed this approach has several problems<footnote>
+	  <para>Given a device file name one cannot reliable find
+related devices. For once names are arbitrary and in a system with
+multiple devices, where only some support VBI capturing, a
+<filename>/dev/video2</filename> is not necessarily related to
+<filename>/dev/vbi2</filename>. The V4L
+<constant>VIDIOCGUNIT</constant> ioctl would require a search for a
+device file with a particular major and minor number.</para>
+	</footnote>, and to make things worse the V4L videodev module
+used to prohibit multiple opens of a device.</para>
+
+      <para>As a remedy the present version of the V4L2 API relaxed the
+concept of device types with specific names and minor numbers. For
+compatibility with old applications drivers must still register different
+minor numbers to assign a default function to the device. But if related
+functions are supported by the driver they must be available under all
+registered minor numbers. The desired function can be selected after
+opening the device as described in <xref linkend="devices" />.</para>
+
+      <para>Imagine a driver supporting video capturing, video
+overlay, raw VBI capturing, and FM radio reception. It registers three
+devices with minor number 0, 64 and 224 (this numbering scheme is
+inherited from the V4L API). Regardless if
+<filename>/dev/video</filename> (81, 0) or
+<filename>/dev/vbi</filename> (81, 224) is opened the application can
+select any one of the video capturing, overlay or VBI capturing
+functions. Without programming (e.&nbsp;g. reading from the device
+with <application>dd</application> or <application>cat</application>)
+<filename>/dev/video</filename> captures video images, while
+<filename>/dev/vbi</filename> captures raw VBI data.
+<filename>/dev/radio</filename> (81, 64) is invariable a radio device,
+unrelated to the video functions. Being unrelated does not imply the
+devices can be used at the same time, however. The &func-open;
+function may very well return an &EBUSY;.</para>
+
+      <para>Besides video input or output the hardware may also
+support audio sampling or playback. If so, these functions are
+implemented as OSS or ALSA PCM devices and eventually OSS or ALSA
+audio mixer. The V4L2 API makes no provisions yet to find these
+related devices. If you have an idea please write to the linux-media
+mailing list: &v4l-ml;.</para>
+    </section>
+
+    <section>
+      <title>Multiple Opens</title>
+
+      <para>In general, V4L2 devices can be opened more than once.
+When this is supported by the driver, users can for example start a
+"panel" application to change controls like brightness or audio
+volume, while another application captures video and audio. In other words, panel
+applications are comparable to an OSS or ALSA audio mixer application.
+When a device supports multiple functions like capturing and overlay
+<emphasis>simultaneously</emphasis>, multiple opens allow concurrent
+use of the device by forked processes or specialized applications.</para>
+
+      <para>Multiple opens are optional, although drivers should
+permit at least concurrent accesses without data exchange, &ie; panel
+applications. This implies &func-open; can return an &EBUSY; when the
+device is already in use, as well as &func-ioctl; functions initiating
+data exchange (namely the &VIDIOC-S-FMT; ioctl), and the &func-read;
+and &func-write; functions.</para>
+
+      <para>Mere opening a V4L2 device does not grant exclusive
+access.<footnote>
+	  <para>Drivers could recognize the
+<constant>O_EXCL</constant> open flag. Presently this is not required,
+so applications cannot know if it really works.</para>
+	</footnote> Initiating data exchange however assigns the right
+to read or write the requested type of data, and to change related
+properties, to this file descriptor. Applications can request
+additional access privileges using the priority mechanism described in
+<xref linkend="app-pri" />.</para>
+    </section>
+
+    <section>
+      <title>Shared Data Streams</title>
+
+      <para>V4L2 drivers should not support multiple applications
+reading or writing the same data stream on a device by copying
+buffers, time multiplexing or similar means. This is better handled by
+a proxy application in user space. When the driver supports stream
+sharing anyway it must be implemented transparently. The V4L2 API does
+not specify how conflicts are solved. <!-- For example O_EXCL when the
+application does not want to be preempted, PROT_READ mmapped buffers
+which can be mapped twice, what happens when image formats do not
+match etc.--></para>
+    </section>
+
+    <section>
+      <title>Functions</title>
+
+    <para>To open and close V4L2 devices applications use the
+&func-open; and &func-close; function, respectively. Devices are
+programmed using the &func-ioctl; function as explained in the
+following sections.</para>
+    </section>
+  </section>
+
+  <section id="querycap">
+    <title>Querying Capabilities</title>
+
+    <para>Because V4L2 covers a wide variety of devices not all
+aspects of the API are equally applicable to all types of devices.
+Furthermore devices of the same type have different capabilities and
+this specification permits the omission of a few complicated and less
+important parts of the API.</para>
+
+    <para>The &VIDIOC-QUERYCAP; ioctl is available to check if the kernel
+device is compatible with this specification, and to query the <link
+linkend="devices">functions</link> and <link linkend="io">I/O
+methods</link> supported by the device. Other features can be queried
+by calling the respective ioctl, for example &VIDIOC-ENUMINPUT;
+to learn about the number, types and names of video connectors on the
+device. Although abstraction is a major objective of this API, the
+ioctl also allows driver specific applications to reliable identify
+the driver.</para>
+
+    <para>All V4L2 drivers must support
+<constant>VIDIOC_QUERYCAP</constant>. Applications should always call
+this ioctl after opening the device.</para>
+  </section>
+
+  <section id="app-pri">
+    <title>Application Priority</title>
+
+    <para>When multiple applications share a device it may be
+desirable to assign them different priorities. Contrary to the
+traditional "rm -rf /" school of thought a video recording application
+could for example block other applications from changing video
+controls or switching the current TV channel. Another objective is to
+permit low priority applications working in background, which can be
+preempted by user controlled applications and automatically regain
+control of the device at a later time.</para>
+
+    <para>Since these features cannot be implemented entirely in user
+space V4L2 defines the &VIDIOC-G-PRIORITY; and &VIDIOC-S-PRIORITY;
+ioctls to request and query the access priority associate with a file
+descriptor. Opening a device assigns a medium priority, compatible
+with earlier versions of V4L2 and drivers not supporting these ioctls.
+Applications requiring a different priority will usually call
+<constant>VIDIOC_S_PRIORITY</constant> after verifying the device with
+the &VIDIOC-QUERYCAP; ioctl.</para>
+
+    <para>Ioctls changing driver properties, such as &VIDIOC-S-INPUT;,
+return an &EBUSY; after another application obtained higher priority.
+An event mechanism to notify applications about asynchronous property
+changes has been proposed but not added yet.</para>
+  </section>
+
+  <section id="video">
+    <title>Video Inputs and Outputs</title>
+

+    <title>Video Standards</title>
+
+    <para>Video devices typically support one or more different video
+standards or variations of standards. Each video input and output may
+support another set of standards. This set is reported by the
+<structfield>std</structfield> field of &v4l2-input; and
+&v4l2-output; returned by the &VIDIOC-ENUMINPUT; and
+&VIDIOC-ENUMOUTPUT; ioctl, respectively.</para>
+
+    <para>V4L2 defines one bit for each analog video standard
+currently in use worldwide, and sets aside bits for driver defined
+standards, &eg; hybrid standards to watch NTSC video tapes on PAL TVs
+and vice versa. Applications can use the predefined bits to select a
+particular standard, although presenting the user a menu of supported
+standards is preferred. To enumerate and query the attributes of the
+supported standards applications use the &VIDIOC-ENUMSTD; ioctl.</para>
+
+    <para>Many of the defined standards are actually just variations
+of a few major standards. The hardware may in fact not distinguish
+between them, or do so internal and switch automatically. Therefore
+enumerated standards also contain sets of one or more standard
+bits.</para>
+
+    <para>Assume a hypothetic tuner capable of demodulating B/PAL,
+G/PAL and I/PAL signals. The first enumerated standard is a set of B
+and G/PAL, switched automatically depending on the selected radio
+frequency in UHF or VHF band. Enumeration gives a "PAL-B/G" or "PAL-I"
+choice. Similar a Composite input may collapse standards, enumerating
+"PAL-B/G/H/I", "NTSC-M" and "SECAM-D/K".<footnote>
+	<para>Some users are already confused by technical terms PAL,
+NTSC and SECAM. There is no point asking them to distinguish between
+B, G, D, or K when the software or hardware can do that
+automatically.</para>
+    </footnote></para>
+
+    <para>To query and select the standard used by the current video
+input or output applications call the &VIDIOC-G-STD; and
+&VIDIOC-S-STD; ioctl, respectively. The <emphasis>received</emphasis>
+standard can be sensed with the &VIDIOC-QUERYSTD; ioctl. Note parameter of all these ioctls is a pointer to a &v4l2-std-id; type (a standard set), <emphasis>not</emphasis> an index into the standard enumeration.<footnote>
+	<para>An alternative to the current scheme is to use pointers
+to indices as arguments of <constant>VIDIOC_G_STD</constant> and
+<constant>VIDIOC_S_STD</constant>, the &v4l2-input; and
+&v4l2-output; <structfield>std</structfield> field would be a set of
+indices like <structfield>audioset</structfield>.</para>
+	<para>Indices are consistent with the rest of the API
+and identify the standard unambiguously. In the present scheme of
+things an enumerated standard is looked up by &v4l2-std-id;. Now the
+standards supported by the inputs of a device can overlap. Just
+assume the tuner and composite input in the example above both
+exist on a device. An enumeration of "PAL-B/G", "PAL-H/I" suggests
+a choice which does not exist. We cannot merge or omit sets, because
+applications would be unable to find the standards reported by
+<constant>VIDIOC_G_STD</constant>. That leaves separate enumerations
+for each input. Also selecting a standard by &v4l2-std-id; can be
+ambiguous. Advantage of this method is that applications need not
+identify the standard indirectly, after enumerating.</para><para>So in
+summary, the lookup itself is unavoidable. The difference is only
+whether the lookup is necessary to find an enumerated standard or to
+switch to a standard by &v4l2-std-id;.</para>

+
+      <para>Different devices exchange different kinds of data with

+datagrams. Even within one kind many different formats are possible,
+in particular an abundance of image formats. Although drivers must
+provide a default and the selection persists across closing and
+reopening a device, applications should always negotiate a data format
+before engaging in data exchange. Negotiation means the application
+asks for a particular format and the driver selects and reports the
+best the hardware can do to satisfy the request. Of course
+applications can also just query the current selection.</para>
+
+      <para>A single mechanism exists to negotiate all data formats
+using the aggregate &v4l2-format; and the &VIDIOC-G-FMT; and
+&VIDIOC-S-FMT; ioctls. Additionally the &VIDIOC-TRY-FMT; ioctl can be
+used to examine what the hardware <emphasis>could</emphasis> do,
+without actually selecting a new data format. The data formats
+supported by the V4L2 API are covered in the respective device section
+in <xref linkend="devices" />. For a closer look at image formats see
+<xref linkend="pixfmt" />.</para>
+
+      <para>The <constant>VIDIOC_S_FMT</constant> ioctl is a major
+turning-point in the initialization sequence. Prior to this point
+multiple panel applications can access the same device concurrently to
+select the current input, change controls or modify other properties.
+The first <constant>VIDIOC_S_FMT</constant> assigns a logical stream
+(video data, VBI data etc.) exclusively to one file descriptor.</para>
+
+      <para>Exclusive means no other application, more precisely no
+other file descriptor, can grab this stream or change device
+properties inconsistent with the negotiated parameters. A video
+standard change for example, when the new standard uses a different
+number of scan lines, can invalidate the selected image format.
+Therefore only the file descriptor owning the stream can make
+invalidating changes. Accordingly multiple file descriptors which
+grabbed different logical streams prevent each other from interfering
+with their settings. When for example video overlay is about to start
+or already in progress, simultaneous video capturing may be restricted
+to the same cropping and image size.</para>
+

+
+      <para>Generally only one logical stream can be assigned to a

+      <title>Scaling Adjustments</title>
+
+      <para>Video hardware can have various cropping, insertion and
+scaling limitations. It may only scale up or down, support only
+discrete scaling factors, or have different scaling abilities in
+horizontal and vertical direction. Also it may not support scaling at
+all. At the same time the &v4l2-crop; rectangle may have to be
+aligned, and both the source and target rectangles may have arbitrary
+upper and lower size limits. In particular the maximum
+<structfield>width</structfield> and <structfield>height</structfield>
+in &v4l2-crop; may be smaller than the
+&v4l2-cropcap;.<structfield>bounds</structfield> area. Therefore, as
+usual, drivers are expected to adjust the requested parameters and
+return the actual values selected.</para>
+
+      <para>Applications can change the source or the target rectangle
+first, as they may prefer a particular image size or a certain area in
+the video signal. If the driver has to adjust both to satisfy hardware
+limitations, the last requested rectangle shall take priority, and the
+driver should preferably adjust the opposite one. The &VIDIOC-TRY-FMT;
+ioctl however shall not change the driver state and therefore only
+adjust the requested rectangle.</para>
+
+      <para>Suppose scaling on a video capture device is restricted to
+a factor 1:1 or 2:1 in either direction and the target image size must
+be a multiple of 16&nbsp;&times;&nbsp;16 pixels. The source cropping
+rectangle is set to defaults, which are also the upper limit in this
+example, of 640&nbsp;&times;&nbsp;400 pixels at offset 0,&nbsp;0. An
+application requests an image size of 300&nbsp;&times;&nbsp;225
+pixels, assuming video will be scaled down from the "full picture"
+accordingly. The driver sets the image size to the closest possible
+values 304&nbsp;&times;&nbsp;224, then chooses the cropping rectangle
+closest to the requested size, that is 608&nbsp;&times;&nbsp;224
+(224&nbsp;&times;&nbsp;2:1 would exceed the limit 400). The offset
+0,&nbsp;0 is still valid, thus unmodified. Given the default cropping
+rectangle reported by <constant>VIDIOC_CROPCAP</constant> the
+application can easily propose another offset to center the cropping
+rectangle.</para>
+
+      <para>Now the application may insist on covering an area using a
+picture aspect ratio closer to the original request, so it asks for a
+cropping rectangle of 608&nbsp;&times;&nbsp;456 pixels. The present
+scaling factors limit cropping to 640&nbsp;&times;&nbsp;384, so the
+driver returns the cropping size 608&nbsp;&times;&nbsp;384 and adjusts
+the image size to closest possible 304&nbsp;&times;&nbsp;192.</para>

+
+    <para>The Video For Linux API was first introduced in Linux 2.1 to
+unify and replace various TV and radio device related interfaces,
+developed independently by driver writers in prior years. Starting
+with Linux 2.5 the much improved V4L2 API replaces the V4L API,
+although existing drivers will continue to support V4L applications in
+the future, either directly or through the V4L2 compatibility layer in
+the <filename>videodev</filename> kernel module translating ioctls on
+the fly. For a transition period not all drivers will support the V4L2
+API.</para>

+    <section>
+      <title>Opening and Closing Devices</title>
+
+      <para>For compatibility reasons the character device file names
+recommended for V4L2 video capture, overlay, radio, teletext and raw
+vbi capture devices did not change from those used by V4L. They are
+listed in <xref linkend="devices" /> and below in <xref
+	  linkend="v4l-dev" />.</para>
+
+      <para>The V4L <filename>videodev</filename> module automatically
+assigns minor numbers to drivers in load order, depending on the
+registered device type. We recommend that V4L2 drivers by default
+register devices with the same numbers, but the system administrator
+can assign arbitrary minor numbers using driver module options. The
+major device number remains 81.</para>

+http://reality.sgi.com/cpirazzi_engr/lg/time/intro.html. [This link is

+(not struct timeval's) and given in nanosecond units. The UST clock
+starts at zero when the system is booted and runs continuously and
+uniformly. It takes a little over 292 years for UST to overflow. There
+is no way to set the UST clock. The regular Linux time-of-day clock
+can be changed periodically, which would cause errors if it were being
+used for timestamping a multimedia stream. A real UST style clock will
+require some support in the kernel that is not there yet. But in
+anticipation, I will change the timestamp field to a 64-bit integer,
+and I will change the v4l2_masterclock_gettime() function (used only

+      <title>X Video Extension</title>
+
+      <para>The X Video Extension (abbreviated XVideo or just Xv) is
+an extension of the X Window system, implemented for example by the
+XFree86 project. Its scope is similar to V4L2, an API to video capture
+and output devices for X clients. Xv allows applications to display
+live video in a window, send window contents to a TV output, and
+capture or output still images in XPixmaps<footnote>
+	  <para>This is not implemented in XFree86.</para>
+	</footnote>. With their implementation XFree86 makes the
+extension available across many operating systems and
+architectures.</para>
+
+      <para>Because the driver is embedded into the X server Xv has a
+number of advantages over the V4L2 <link linkend="overlay">video
+overlay interface</link>. The driver can easily determine the overlay
+target, &ie; visible graphics memory or off-screen buffers for a
+destructive overlay. It can program the RAMDAC for a non-destructive
+overlay, scaling or color-keying, or the clipping functions of the
+video capture hardware, always in sync with drawing operations or
+windows moving or changing their stacking order.</para>
+
+      <para>To combine the advantages of Xv and V4L a special Xv
+driver exists in XFree86 and XOrg, just programming any overlay capable
+Video4Linux device it finds. To enable it
+<filename>/etc/X11/XF86Config</filename> must contain these lines:</para>
+      <para><screen>
+Section "Module"
+    Load "v4l"
+EndSection</screen></para>
+
+      <para>As of XFree86 4.2 this driver still supports only V4L
+ioctls, however it should work just fine with all V4L2 devices through
+the V4L2 backward-compatibility layer. Since V4L2 permits multiple
+opens it is possible (if supported by the V4L2 driver) to capture
+video while an X client requested video overlay. Restrictions of
+simultaneous capturing and overlay are discussed in <xref
+	  linkend="overlay" /> apply.</para>
+
+      <para>Only marginally related to V4L2, XFree86 extended Xv to

+    <title>User Controls</title>
+
+    <para>Devices typically have a number of user-settable controls
+such as brightness, saturation and so on, which would be presented to
+the user on a graphical user interface. But, different devices
+will have different controls available, and furthermore, the range of
+possible values, and the default value will vary from device to
+device. The control ioctls provide the information and a mechanism to
+create a nice user interface for these controls that will work
+correctly with any device.</para>
+
+    <para>All controls are accessed using an ID value. V4L2 defines
+several IDs for specific purposes. Drivers can also implement their
+own custom controls using <constant>V4L2_CID_PRIVATE_BASE</constant>
+and higher values. The pre-defined control IDs have the prefix
+<constant>V4L2_CID_</constant>, and are listed in <xref
+linkend="control-id" />. The ID is used when querying the attributes of
+a control, and when getting or setting the current value.</para>
+
+    <para>Generally applications should present controls to the user
+without assumptions about their purpose. Each control comes with a
+name string the user is supposed to understand. When the purpose is
+non-intuitive the driver writer should provide a user manual, a user
+interface plug-in or a driver specific panel application. Predefined
+IDs were introduced to change a few controls programmatically, for
+example to mute a device during a channel switch.</para>
+
+    <para>Drivers may enumerate different controls after switching
+the current video input or output, tuner or modulator, or audio input
+or output. Different in the sense of other bounds, another default and
+current value, step size or other menu items. A control with a certain
+<emphasis>custom</emphasis> ID can also change name and
+type.<footnote>
+	<para>It will be more convenient for applications if drivers
+make use of the <constant>V4L2_CTRL_FLAG_DISABLED</constant> flag, but
+that was never required.</para>
+      </footnote> Control values are stored globally, they do not
+change when switching except to stay within the reported bounds. They
+also do not change &eg; when the device is opened or closed, when the
+tuner radio frequency is changed or generally never without
+application request. Since V4L2 specifies no event mechanism, panel
+applications intended to cooperate with other panel applications (be
+they built into a larger application, as a TV viewer) may need to
+regularly poll control values to update their user
+interface.<footnote>
+	<para>Applications could call an ioctl to request events.
+After another process called &VIDIOC-S-CTRL; or another ioctl changing
+shared properties the &func-select; function would indicate
+readability until any ioctl (querying the properties) is
+called.</para>

+
+      <para>The control mechanism as originally designed was meant
+to be used for user settings (brightness, saturation, etc). However,
+it turned out to be a very useful model for implementing more
+complicated driver APIs where each driver implements only a subset of
+a larger API.</para>
+
+      <para>The MPEG encoding API was the driving force behind
+designing and implementing this extended control mechanism: the MPEG
+standard is quite large and the currently supported hardware MPEG
+encoders each only implement a subset of this standard. Further more,
+many parameters relating to how the video is encoded into an MPEG
+stream are specific to the MPEG encoding chip since the MPEG standard
+only defines the format of the resulting MPEG stream, not how the
+video is actually encoded into that format.</para>
+
+      <para>Unfortunately, the original control API lacked some
+features needed for these new uses and so it was extended into the
+(not terribly originally named) extended control API.</para>
+
+      <para>Even though the MPEG encoding API was the first effort
+to use the Extended Control API, nowadays there are also other classes
+of Extended Controls, such as Camera Controls and FM Transmitter Controls.
+The Extended Controls API as well as all Extended Controls classes are
+described in the following text.</para>
+    </section>
+
+    <section>
+      <title>The Extended Control API</title>
+
+      <para>Three new ioctls are available: &VIDIOC-G-EXT-CTRLS;,
+&VIDIOC-S-EXT-CTRLS; and &VIDIOC-TRY-EXT-CTRLS;. These ioctls act on
+arrays of controls (as opposed to the &VIDIOC-G-CTRL; and
+&VIDIOC-S-CTRL; ioctls that act on a single control). This is needed
+since it is often required to atomically change several controls at
+once.</para>
+
+      <para>Each of the new ioctls expects a pointer to a
+&v4l2-ext-controls;. This structure contains a pointer to the control
+array, a count of the number of controls in that array and a control
+class. Control classes are used to group similar controls into a
+single class. For example, control class
+<constant>V4L2_CTRL_CLASS_USER</constant> contains all user controls
+(&ie; all controls that can also be set using the old
+<constant>VIDIOC_S_CTRL</constant> ioctl). Control class
+<constant>V4L2_CTRL_CLASS_MPEG</constant> contains all controls
+relating to MPEG encoding, etc.</para>
+
+      <para>All controls in the control array must belong to the
+specified control class. An error is returned if this is not the
+case.</para>
+
+      <para>It is also possible to use an empty control array (count
+== 0) to check whether the specified control class is
+supported.</para>
+
+      <para>The control array is a &v4l2-ext-control; array. The
+<structname>v4l2_ext_control</structname> structure is very similar to
+&v4l2-control;, except for the fact that it also allows for 64-bit
+values and pointers to be passed.</para>
+
+      <para>It is important to realize that due to the flexibility of
+controls it is necessary to check whether the control you want to set
+actually is supported in the driver and what the valid range of values
+is. So use the &VIDIOC-QUERYCTRL; and &VIDIOC-QUERYMENU; ioctls to
+check this. Also note that it is possible that some of the menu
+indices in a control of type <constant>V4L2_CTRL_TYPE_MENU</constant>
+may not be supported (<constant>VIDIOC_QUERYMENU</constant> will
+return an error). A good example is the list of supported MPEG audio
+bitrates. Some drivers only support one or two bitrates, others
+support a wider range.</para>

+      <title>Enumerating Extended Controls</title>
+
+      <para>The recommended way to enumerate over the extended
+controls is by using &VIDIOC-QUERYCTRL; in combination with the
+<constant>V4L2_CTRL_FLAG_NEXT_CTRL</constant> flag:</para>
+
+      <informalexample>
+	<programlisting>
+&v4l2-queryctrl; qctrl;
+
+qctrl.id = V4L2_CTRL_FLAG_NEXT_CTRL;
+while (0 == ioctl (fd, &VIDIOC-QUERYCTRL;, &amp;qctrl)) {
+	/* ... */
+	qctrl.id |= V4L2_CTRL_FLAG_NEXT_CTRL;
+}
+</programlisting>
+      </informalexample>
+
+      <para>The initial control ID is set to 0 ORed with the
+<constant>V4L2_CTRL_FLAG_NEXT_CTRL</constant> flag. The
+<constant>VIDIOC_QUERYCTRL</constant> ioctl will return the first
+control with a higher ID than the specified one. When no such controls
+are found an error is returned.</para>
+
+      <para>If you want to get all controls within a specific control
+class, then you can set the initial
+<structfield>qctrl.id</structfield> value to the control class and add
+an extra check to break out of the loop when a control of another
+control class is found:</para>
+
+      <informalexample>
+	<programlisting>
+qctrl.id = V4L2_CTRL_CLASS_MPEG | V4L2_CTRL_FLAG_NEXT_CTRL;
+while (0 == ioctl (fd, &VIDIOC-QUERYCTRL;, &amp;qctrl)) {
+	if (V4L2_CTRL_ID2CLASS (qctrl.id) != V4L2_CTRL_CLASS_MPEG)
+		break;
+		/* ... */
+		qctrl.id |= V4L2_CTRL_FLAG_NEXT_CTRL;
+	}
+</programlisting>
+      </informalexample>
+
+      <para>The 32-bit <structfield>qctrl.id</structfield> value is
+subdivided into three bit ranges: the top 4 bits are reserved for
+flags (&eg; <constant>V4L2_CTRL_FLAG_NEXT_CTRL</constant>) and are not
+actually part of the ID. The remaining 28 bits form the control ID, of
+which the most significant 12 bits define the control class and the
+least significant 16 bits identify the control within the control
+class. It is guaranteed that these last 16 bits are always non-zero
+for controls. The range of 0x1000 and up are reserved for
+driver-specific controls. The macro
+<constant>V4L2_CTRL_ID2CLASS(id)</constant> returns the control class
+ID based on a control ID.</para>
+
+      <para>If the driver does not support extended controls, then
+<constant>VIDIOC_QUERYCTRL</constant> will fail when used in
+combination with <constant>V4L2_CTRL_FLAG_NEXT_CTRL</constant>. In
+that case the old method of enumerating control should be used (see
+1.8). But if it is supported, then it is guaranteed to enumerate over
+all controls, including driver-private controls.</para>

+
+    <section>
+      <title>Creating Control Panels</title>
+
+      <para>It is possible to create control panels for a graphical
+user interface where the user can select the various controls.
+Basically you will have to iterate over all controls using the method
+described above. Each control class starts with a control of type
+<constant>V4L2_CTRL_TYPE_CTRL_CLASS</constant>.
+<constant>VIDIOC_QUERYCTRL</constant> will return the name of this
+control class which can be used as the title of a tab page within a
+control panel.</para>
+
+      <para>The flags field of &v4l2-queryctrl; also contains hints on
+the behavior of the control. See the &VIDIOC-QUERYCTRL; documentation
+for more details.</para>

+  <title>Video Overlay Interface</title>
+  <subtitle>Also known as Framebuffer Overlay or Previewing</subtitle>
+
+  <para>Video overlay devices have the ability to genlock (TV-)video
+into the (VGA-)video signal of a graphics card, or to store captured
+images directly in video memory of a graphics card, typically with
+clipping. This can be considerable more efficient than capturing
+images and displaying them by other means. In the old days when only
+nuclear power plants needed cooling towers this used to be the only
+way to put live video into a window.</para>
+
+  <para>Video overlay devices are accessed through the same character
+special files as <link linkend="capture">video capture</link> devices.
+Note the default function of a <filename>/dev/video</filename> device
+is video capturing. The overlay function is only available after
+calling the &VIDIOC-S-FMT; ioctl.</para>
+
+    <para>The driver may support simultaneous overlay and capturing
+using the read/write and streaming I/O methods. If so, operation at
+the nominal frame rate of the video standard is not guaranteed. Frames
+may be directed away from overlay to capture, or one field may be used
+for overlay and the other for capture if the capture parameters permit
+this.</para>
+
+  <para>Applications should use different file descriptors for
+capturing and overlay. This must be supported by all drivers capable
+of simultaneous capturing and overlay. Optionally these drivers may
+also permit capturing and overlay with a single file descriptor for
+compatibility with V4L and earlier versions of V4L2.<footnote>
+	<para>A common application of two file descriptors is the
+XFree86 <link linkend="xvideo">Xv/V4L</link> interface driver and
+a V4L2 application. While the X server controls video overlay, the
+application can take advantage of memory mapping and DMA.</para>
+	<para>In the opinion of the designers of this API, no driver
+writer taking the efforts to support simultaneous capturing and
+overlay will restrict this ability by requiring a single file
+descriptor, as in V4L and earlier versions of V4L2. Making this
+optional means applications depending on two file descriptors need
+backup routines to be compatible with all drivers, which is
+considerable more work than using two fds in applications which do
+not. Also two fd's fit the general concept of one file descriptor for
+each logical stream. Hence as a complexity trade-off drivers
+<emphasis>must</emphasis> support two file descriptors and
+<emphasis>may</emphasis> support single fd operation.</para>

+    <para>Before overlay can commence applications must program the

+the frame buffer and the image format, for example RGB 5:6:5. The
+&VIDIOC-G-FBUF; and &VIDIOC-S-FBUF; ioctls are available to get
+and set these parameters, respectively. The
+<constant>VIDIOC_S_FBUF</constant> ioctl is privileged because it
+allows to set up DMA into physical memory, bypassing the memory
+protection mechanisms of the kernel. Only the superuser can change the
+frame buffer address and size. Users are not supposed to run TV
+applications as root or with SUID bit set. A small helper application
+with suitable privileges should query the graphics system and program
+the V4L2 driver at the appropriate time.</para>
+
+    <para>Some devices add the video overlay to the output signal
+of the graphics card. In this case the frame buffer is not modified by
+the video device, and the frame buffer address and pixel format are
+not needed by the driver. The <constant>VIDIOC_S_FBUF</constant> ioctl
+is not privileged. An application can check for this type of device by

+

+initialization at minimum requires to reset the parameters to
+defaults. An example is given in <xref linkend="crop" />.</para>
+
+    <para>The overlay window is described by a &v4l2-window;. It
+defines the size of the image, its position over the graphics surface
+and the clipping to be applied. To get the current parameters
+applications set the <structfield>type</structfield> field of a
+&v4l2-format; to <constant>V4L2_BUF_TYPE_VIDEO_OVERLAY</constant> and
+call the &VIDIOC-G-FMT; ioctl. The driver fills the
+<structname>v4l2_window</structname> substructure named
+<structfield>win</structfield>. It is not possible to retrieve a
+previously programmed clipping list or bitmap.</para>
+
+    <para>To program the overlay window applications set the
+<structfield>type</structfield> field of a &v4l2-format; to
+<constant>V4L2_BUF_TYPE_VIDEO_OVERLAY</constant>, initialize the
+<structfield>win</structfield> substructure and call the
+&VIDIOC-S-FMT; ioctl. The driver adjusts the parameters against

+  <title>Raw VBI Data Interface</title>
+
+  <para>VBI is an abbreviation of Vertical Blanking Interval, a gap
+in the sequence of lines of an analog video signal. During VBI
+no picture information is transmitted, allowing some time while the
+electron beam of a cathode ray tube TV returns to the top of the
+screen. Using an oscilloscope you will find here the vertical
+synchronization pulses and short data packages ASK
+modulated<footnote><para>ASK: Amplitude-Shift Keying. A high signal
+level represents a '1' bit, a low level a '0' bit.</para></footnote>
+onto the video signal. These are transmissions of services such as
+Teletext or Closed Caption.</para>
+
+  <para>Subject of this interface type is raw VBI data, as sampled off
+a video signal, or to be added to a signal for output.
+The data format is similar to uncompressed video images, a number of
+lines times a number of samples per line, we call this a VBI image.</para>
+
+  <para>Conventionally V4L2 VBI devices are accessed through character
+device special files named <filename>/dev/vbi</filename> and
+<filename>/dev/vbi0</filename> to <filename>/dev/vbi31</filename> with
+major number 81 and minor numbers 224 to 255.
+<filename>/dev/vbi</filename> is typically a symbolic link to the
+preferred VBI device. This convention applies to both input and output
+devices.</para>
+
+  <para>To address the problems of finding related video and VBI
+devices VBI capturing and output is also available as device function
+under <filename>/dev/video</filename>. To capture or output raw VBI
+data with these devices applications must call the &VIDIOC-S-FMT;
+ioctl. Accessed as <filename>/dev/vbi</filename>, raw VBI capturing
+or output is the default device function.</para>

+
+      <para>Raw VBI sampling abilities can vary, in particular the
+sampling frequency. To properly interpret the data V4L2 specifies an
+ioctl to query the sampling parameters. Moreover, to allow for some
+flexibility applications can also suggest different parameters.</para>

+reset at &func-open; time to permit Unix tool chains, programming a
+device and then reading from it as if it was a plain file. Well
+written V4L2 applications should always ensure they really get what
+they want, requesting reasonable parameters and then checking if the
+actual parameters are suitable.</para>
+
+      <para>To query the current raw VBI capture parameters
+applications set the <structfield>type</structfield> field of a
+&v4l2-format; to <constant>V4L2_BUF_TYPE_VBI_CAPTURE</constant> or
+<constant>V4L2_BUF_TYPE_VBI_OUTPUT</constant>, and call the
+&VIDIOC-G-FMT; ioctl with a pointer to this structure. Drivers fill
+the &v4l2-vbi-format; <structfield>vbi</structfield> member of the
+<structfield>fmt</structfield> union.</para>
+
+      <para>To request different parameters applications set the
+<structfield>type</structfield> field of a &v4l2-format; as above and
+initialize all fields of the &v4l2-vbi-format;
+<structfield>vbi</structfield> member of the
+<structfield>fmt</structfield> union, or better just modify the
+results of <constant>VIDIOC_G_FMT</constant>, and call the
+&VIDIOC-S-FMT; ioctl with a pointer to this structure. Drivers return
+an &EINVAL; only when the given parameters are ambiguous, otherwise
+they modify the parameters according to the hardware capabilites and
+return the actual parameters. When the driver allocates resources at
+this point, it may return an &EBUSY; to indicate the returned
+parameters are valid but the required resources are currently not
+available. That may happen for instance when the video and VBI areas
+to capture would overlap, or when the driver supports multiple opens
+and another process already requested VBI capturing or output. Anyway,
+applications must expect other resource allocation points which may
+return <errorcode>EBUSY</errorcode>, at the &VIDIOC-STREAMON; ioctl
+and the first read(), write() and select() call.</para>
+
+      <para>VBI devices must implement both the
+<constant>VIDIOC_G_FMT</constant> and
+<constant>VIDIOC_S_FMT</constant> ioctl, even if
+<constant>VIDIOC_S_FMT</constant> ignores all requests and always
+returns default parameters as <constant>VIDIOC_G_FMT</constant> does.
+<constant>VIDIOC_TRY_FMT</constant> is optional.</para>

+    <para>To find out which data services are supported by the
+hardware applications can call the &VIDIOC-G-SLICED-VBI-CAP; ioctl.
+All drivers implementing the sliced VBI interface must support this
+ioctl. The results may differ from those of the &VIDIOC-S-FMT; ioctl
+when the number of VBI lines the hardware can capture or output per
+frame, or the number of services it can identify on a given line are
+limited. For example on PAL line 16 the hardware may be able to look
+for a VPS or Teletext signal, but not both at the same time.</para>
+
+    <para>To determine the currently selected services applications
+set the <structfield>type </structfield> field of &v4l2-format; to
+<constant> V4L2_BUF_TYPE_SLICED_VBI_CAPTURE</constant> or <constant>
+V4L2_BUF_TYPE_SLICED_VBI_OUTPUT</constant>, and the &VIDIOC-G-FMT;
+ioctl fills the <structfield>fmt.sliced</structfield> member, a
+&v4l2-sliced-vbi-format;.</para>
+
+    <para>Applications can request different parameters by
+initializing or modifying the <structfield>fmt.sliced</structfield>
+member and calling the &VIDIOC-S-FMT; ioctl with a pointer to the
+<structname>v4l2_format</structname> structure.</para>
+
+    <para>The sliced VBI API is more complicated than the raw VBI API
+because the hardware must be told which VBI service to expect on each
+scan line. Not all services may be supported by the hardware on all
+lines (this is especially true for VBI output where Teletext is often
+unsupported and other services can only be inserted in one specific
+line). In many cases, however, it is sufficient to just set the
+<structfield>service_set</structfield> field to the required services
+and let the driver fill the <structfield>service_lines</structfield>
+array according to hardware capabilities. Only if more precise control
+is needed should the programmer set the
+<structfield>service_lines</structfield> array explicitly.</para>
+
+    <para>The &VIDIOC-S-FMT; ioctl modifies the parameters
+according to hardware capabilities. When the driver allocates
+resources at this point, it may return an &EBUSY; if the required
+resources are temporarily unavailable. Other resource allocation
+points which may return <errorcode>EBUSY</errorcode> can be the
+&VIDIOC-STREAMON; ioctl and the first &func-read;, &func-write; and

+  <para>This interface aims at devices receiving and demodulating
+Teletext data [<xref linkend="ets300706" />, <xref linkend="itu653" />], evaluating the
+Teletext packages and storing formatted pages in cache memory. Such
+devices are usually implemented as microcontrollers with serial
+interface (I<superscript>2</superscript>C) and can be found on older
+TV cards, dedicated Teletext decoding cards and home-brew devices
+connected to the PC parallel port.</para>
+
+  <para>The Teletext API was designed by Martin Buck. It is defined in
+the kernel header file <filename>linux/videotext.h</filename>, the
+specification is available from <ulink url="http://home.pages.de/~videotext/">
+http://home.pages.de/~videotext/</ulink>. (Videotext is the name of
+the German public television Teletext service.) Conventional character
+device file names are <filename>/dev/vtx</filename> and
+<filename>/dev/vttuner</filename>, with device number 83, 0 and 83, 16
+respectively. A similar interface exists for the Philips SAA5249
+Teletext decoder [specification?] with character device file names
+<filename>/dev/tlkN</filename>, device number 102, N.</para>
+
+  <para>Eventually the Teletext API was integrated into the V4L API
+with character device file names <filename>/dev/vtx0</filename> to
+<filename>/dev/vtx31</filename>, device major number 81, minor numbers
+192 to 223. For reference the V4L Teletext API specification is
+reproduced here in full: "Teletext interfaces talk the existing VTX
+API." Teletext devices with major number 83 and 102 will be removed in
+Linux 2.6.</para>
+
+  <para>There are no plans to replace the Teletext API or to integrate
+it into V4L2. Please write to the linux-media mailing list: &v4l-ml;
+when the need arises.</para>

+in it whether the argument is an input, output or read/write
+parameter, and the size of the argument <parameter>argp</parameter> in
+bytes. Macros and defines specifying V4L2 ioctl requests are located
+in the <link linkend="videodev">videodev.h</link> header file.
+Applications should use their own copy, not include the version in the
+kernel sources on the system they compile on. All V4L2 ioctl requests,

+<returnvalue>-1</returnvalue> is returned, when the ioctl takes an
+output or read/write parameter it remains unmodified, and the
+<varname>errno</varname> variable is set appropriately. See below for
+possible error codes. Generic errors like <errorcode>EBADF</errorcode>
+or <errorcode>EFAULT</errorcode> are not listed in the sections
+discussing individual ioctl requests.</para>

+
+    <para><function>read()</function> attempts to read up to
+<parameter>count</parameter> bytes from file descriptor
+<parameter>fd</parameter> into the buffer starting at
+<parameter>buf</parameter>. The layout of the data in the buffer is
+discussed in the respective device interface section, see ##. If <parameter>count</parameter> is zero,
+<function>read()</function> returns zero and has no other results. If
+<parameter>count</parameter> is greater than
+<constant>SSIZE_MAX</constant>, the result is unspecified. Regardless
+of the <parameter>count</parameter> value each
+<function>read()</function> call will provide at most one frame (two
+fields) worth of data.</para>
+
+    <para>By default <function>read()</function> blocks until data
+becomes available. When the <constant>O_NONBLOCK</constant> flag was
+given to the &func-open; function it
+returns immediately with an &EAGAIN; when no data is available. The
+&func-select; or &func-poll; functions
+can always be used to suspend execution until data becomes available. All
+drivers supporting the <function>read()</function> function must also
+support <function>select()</function> and
+<function>poll()</function>.</para>
+
+    <para>Drivers can implement read functionality in different
+ways, using a single or multiple buffers and discarding the oldest or
+newest frames once the internal buffers are filled.</para>
+
+    <para><function>read()</function> never returns a "snapshot" of a
+buffer being filled. Using a single buffer the driver will stop
+capturing when the application starts reading the buffer until the
+read is finished. Thus only the period of the vertical blanking
+interval is available for reading, or the capture rate must fall below
+the nominal frame rate of the video standard.</para>
+
+<para>The behavior of
+<function>read()</function> when called during the active picture
+period or the vertical blanking separating the top and bottom field
+depends on the discarding policy. A driver discarding the oldest
+frames keeps capturing into an internal buffer, continuously
+overwriting the previously, not read frame, and returns the frame
+being received at the time of the <function>read()</function> call as
+soon as it is complete.</para>
+
+    <para>A driver discarding the newest frames stops capturing until
+the next <function>read()</function> call. The frame being received at
+<function>read()</function> time is discarded, returning the following
+frame instead. Again this implies a reduction of the capture rate to
+one half or less of the nominal frame rate. An example of this model
+is the video read mode of the bttv driver, initiating a DMA to user
+memory when <function>read()</function> is called and returning when
+the DMA finished.</para>
+
+    <para>In the multiple buffer model drivers maintain a ring of
+internal buffers, automatically advancing to the next free buffer.
+This allows continuous capturing when the application can empty the
+buffers fast enough. Again, the behavior when the driver runs out of
+free buffers depends on the discarding policy.</para>
+
+    <para>Applications can get and set the number of buffers used
+internally by the driver with the &VIDIOC-G-PARM; and &VIDIOC-S-PARM;
+ioctls. They are optional, however. The discarding policy is not
+reported and cannot be changed. For minimum requirements see <xref
+	linkend="devices" />.</para>

+    <title>Return Value</title>
+
+    <para>On success, the number of bytes read is returned. It is not
+an error if this number is smaller than the number of bytes requested,
+or the amount of data required for one frame. This may happen for
+example because <function>read()</function> was interrupted by a
+signal. On error, -1 is returned, and the <varname>errno</varname>
+variable is set appropriately. In this case the next read will start
+at the beginning of a new frame. Possible error codes are:</para>

+  <title>Input/Output</title>
+
+  <para>The V4L2 API defines several different methods to read from or
+write to a device. All drivers exchanging data with applications must
+support at least one of them.</para>
+
+  <para>The classic I/O method using the <function>read()</function>
+and <function>write()</function> function is automatically selected
+after opening a V4L2 device. When the driver does not support this
+method attempts to read or write will fail at any time.</para>
+
+  <para>Other methods must be negotiated. To select the streaming I/O
+method with memory mapped or user buffers applications call the
+&VIDIOC-REQBUFS; ioctl. The asynchronous I/O method is not defined
+yet.</para>
+
+  <para>Video overlay can be considered another I/O method, although
+the application does not directly receive the image data. It is
+selected by initiating video overlay with the &VIDIOC-S-FMT; ioctl.
+For more information see <xref linkend="overlay" />.</para>
+
+  <para>Generally exactly one I/O method, including overlay, is
+associated with each file descriptor. The only exceptions are
+applications not exchanging data with a driver ("panel applications",
+see <xref linkend="open" />) and drivers permitting simultaneous video capturing
+and overlay using the same file descriptor, for compatibility with V4L
+and earlier versions of V4L2.</para>
+
+  <para><constant>VIDIOC_S_FMT</constant> and
+<constant>VIDIOC_REQBUFS</constant> would permit this to some degree,
+but for simplicity drivers need not support switching the I/O method
+(after first switching away from read/write) other than by closing
+and reopening the device.</para>
+
+  <para>The following sections describe the various I/O methods in
+more detail.</para>
+
+  <section id="rw">
+    <title>Read/Write</title>
+
+    <para>Input and output devices support the

+respectively, when the <constant>V4L2_CAP_READWRITE</constant> flag in
+the <structfield>capabilities</structfield> field of &v4l2-capability;
+returned by the &VIDIOC-QUERYCAP; ioctl is set.</para>
+
+    <para>Drivers may need the CPU to copy the data, but they may also
+support DMA to or from user memory, so this I/O method is not
+necessarily less efficient than other methods merely exchanging buffer
+pointers. It is considered inferior though because no meta-information
+like frame counters or timestamps are passed. This information is
+necessary to recognize frame dropping and to synchronize with other
+data streams. However this is also the simplest I/O method, requiring
+little or no setup to exchange data. It permits command line stunts
+like this (the <application>vidctrl</application> tool is
+fictitious):</para>

+    </informalexample>
+
+    <para>To read from the device applications use the
+&func-read; function, to write the &func-write; function.
+Drivers must implement one I/O method if they
+exchange data with applications, but it need not be this.<footnote>
+	<para>It would be desirable if applications could depend on
+drivers supporting all I/O interfaces, but as much as the complex
+memory mapping I/O can be inadequate for some devices we have no
+reason to require this interface, which is most useful for simple
+applications capturing still images.</para>
+      </footnote> When reading or writing is supported, the driver
+must also support the &func-select; and &func-poll;
+function.<footnote>
+	<para>At the driver level <function>select()</function> and
+<function>poll()</function> are the same, and

+    <title>Streaming I/O (Memory Mapping)</title>
+
+    <para>Input and output devices support this I/O method when the
+<constant>V4L2_CAP_STREAMING</constant> flag in the
+<structfield>capabilities</structfield> field of &v4l2-capability;
+returned by the &VIDIOC-QUERYCAP; ioctl is set. There are two
+streaming methods, to determine if the memory mapping flavor is
+supported applications must call the &VIDIOC-REQBUFS; ioctl.</para>
+
+    <para>Streaming is an I/O method where only pointers to buffers
+are exchanged between application and driver, the data itself is not
+copied. Memory mapping is primarily intended to map buffers in device
+memory into the application's address space. Device memory can be for
+example the video memory on a graphics card with a video capture
+add-on. However, being the most efficient I/O method available for a
+long time, many other drivers support streaming as well, allocating
+buffers in DMA-able main memory.</para>
+
+    <para>A driver can support many sets of buffers. Each set is
+identified by a unique buffer type value. The sets are independent and
+each set can hold a different type of data. To access different sets
+at the same time different file descriptors must be used.<footnote>
+	<para>One could use one file descriptor and set the buffer
+type field accordingly when calling &VIDIOC-QBUF; etc., but it makes
+the <function>select()</function> function ambiguous. We also like the
+clean approach of one file descriptor per logical stream. Video
+overlay for example is also a logical stream, although the CPU is not
+needed for continuous operation.</para>
+      </footnote></para>
+
+    <para>To allocate device buffers applications call the
+&VIDIOC-REQBUFS; ioctl with the desired number of buffers and buffer
+type, for example <constant>V4L2_BUF_TYPE_VIDEO_CAPTURE</constant>.
+This ioctl can also be used to change the number of buffers or to free
+the allocated memory, provided none of the buffers are still
+mapped.</para>
+
+    <para>Before applications can access the buffers they must map
+them into their address space with the &func-mmap; function. The
+location of the buffers in device memory can be determined with the
+&VIDIOC-QUERYBUF; ioctl. The <structfield>m.offset</structfield> and
+<structfield>length</structfield> returned in a &v4l2-buffer; are
+passed as sixth and second parameter to the
+<function>mmap()</function> function. The offset and length values
+must not be modified. Remember the buffers are allocated in physical
+memory, as opposed to virtual memory which can be swapped out to disk.
+Applications should free the buffers as soon as possible with the
+&func-munmap; function.</para>

+
+    <para>Conceptually streaming drivers maintain two buffer queues, an incoming
+and an outgoing queue. They separate the synchronous capture or output
+operation locked to a video clock from the application which is
+subject to random disk or network delays and preemption by
+other processes, thereby reducing the probability of data loss.
+The queues are organized as FIFOs, buffers will be
+output in the order enqueued in the incoming FIFO, and were
+captured in the order dequeued from the outgoing FIFO.</para>
+
+    <para>The driver may require a minimum number of buffers enqueued
+at all times to function, apart of this no limit exists on the number
+of buffers applications can enqueue in advance, or dequeue and
+process. They can also enqueue in a different order than buffers have
+been dequeued, and the driver can <emphasis>fill</emphasis> enqueued
+<emphasis>empty</emphasis> buffers in any order. <footnote>
+	<para>Random enqueue order permits applications processing
+images out of order (such as video codecs) to return buffers earlier,
+reducing the probability of data loss. Random fill order allows
+drivers to reuse buffers on a LIFO-basis, taking advantage of caches
+holding scatter-gather lists and the like.</para>
+      </footnote> The index number of a buffer (&v4l2-buffer;
+<structfield>index</structfield>) plays no role here, it only
+identifies the buffer.</para>
+
+    <para>Initially all mapped buffers are in dequeued state,
+inaccessible by the driver. For capturing applications it is customary
+to first enqueue all mapped buffers, then to start capturing and enter
+the read loop. Here the application waits until a filled buffer can be
+dequeued, and re-enqueues the buffer when the data is no longer
+needed. Output applications fill and enqueue buffers, when enough
+buffers are stacked up the output is started with
+<constant>VIDIOC_STREAMON</constant>. In the write loop, when
+the application runs out of free buffers, it must wait until an empty
+buffer can be dequeued and reused.</para>
+
+    <para>To enqueue and dequeue a buffer applications use the
+&VIDIOC-QBUF; and &VIDIOC-DQBUF; ioctl. The status of a buffer being
+mapped, enqueued, full or empty can be determined at any time using the
+&VIDIOC-QUERYBUF; ioctl. Two methods exist to suspend execution of the
+application until one or more buffers can be dequeued. By default
+<constant>VIDIOC_DQBUF</constant> blocks when no buffer is in the
+outgoing queue. When the <constant>O_NONBLOCK</constant> flag was
+given to the &func-open; function, <constant>VIDIOC_DQBUF</constant>
+returns immediately with an &EAGAIN; when no buffer is available. The
+&func-select; or &func-poll; function are always available.</para>
+
+    <para>To start and stop capturing or output applications call the
+&VIDIOC-STREAMON; and &VIDIOC-STREAMOFF; ioctl. Note
+<constant>VIDIOC_STREAMOFF</constant> removes all buffers from both
+queues as a side effect. Since there is no notion of doing anything
+"now" on a multitasking system, if an application needs to synchronize
+with another event it should examine the &v4l2-buffer;
+<structfield>timestamp</structfield> of captured buffers, or set the
+field before enqueuing buffers for output.</para>

+    <para>Buffer addresses and sizes are passed on the fly with the
+&VIDIOC-QBUF; ioctl. Although buffers are commonly cycled,
+applications can pass different addresses and sizes at each
+<constant>VIDIOC_QBUF</constant> call. If required by the hardware the
+driver swaps memory pages within physical memory to create a
+continuous area of memory. This happens transparently to the
+application in the virtual memory subsystem of the kernel. When buffer
+pages have been swapped out to disk they are brought back and finally
+locked in physical memory for DMA.<footnote>
+	<para>We expect that frequently used buffers are typically not
+swapped out. Anyway, the process of swapping, locking or generating
+scatter-gather lists may be time consuming. The delay can be masked by
+the depth of the incoming buffer queue, and perhaps by maintaining
+caches assuming a buffer will be soon enqueued again. On the other
+hand, to optimize memory usage drivers can limit the number of buffers
+locked in advance and recycle the most recently used buffers first. Of
+course, the pages of empty buffers in the incoming queue need not be
+saved to disk. Output buffers must be saved on the incoming and
+outgoing queue because an application may share them with other
+processes.</para>

+
+    <para>Filled or displayed buffers are dequeued with the

+also unlocked when &VIDIOC-STREAMOFF; is called, &VIDIOC-REQBUFS;, or
+when the device is closed. Applications must take care not to free
+buffers without dequeuing. For once, the buffers remain locked until
+further, wasting physical memory. Second the driver will not be
+notified when the memory is returned to the application's free list
+and subsequently reused for other purposes, possibly completing the
+requested DMA and overwriting valuable data.</para>

+    <para>For capturing applications it is customary to enqueue a

+    <para>A buffer contains data exchanged by application and

+
+      <para>Nominally timestamps refer to the first data byte transmitted.
+In practice however the wide range of hardware covered by the V4L2 API
+limits timestamp accuracy. Often an interrupt routine will
+sample the system clock shortly after the field or frame was stored
+completely in memory. So applications must expect a constant
+difference up to one field or frame period plus a small (few scan
+lines) random error. The delay and error can be much
+larger due to compression or transmission over an external bus when
+the frames are not properly stamped by the sender. This is frequently
+the case with USB cameras. Here timestamps refer to the instant the
+field or frame was received by the driver, not the capture time. These
+devices identify by not enumerating any video standards, see <xref
+linkend="standard" />.</para>
+
+      <para>Similar limitations apply to output timestamps. Typically
+the video hardware locks to a clock controlling the video timing, the
+horizontal and vertical synchronization pulses. At some point in the
+line sequence, possibly the vertical blanking, an interrupt routine
+samples the system clock, compares against the timestamp and programs
+the hardware to repeat the previous field or frame, or to display the
+buffer contents.</para>
+
+      <para>Apart of limitations of the video device and natural
+inaccuracies of all clocks, it should be noted system time itself is
+not perfectly stable. It can be affected by power saving cycles,
+warped to insert leap seconds, or even turned back or forth by the
+system administrator affecting long term measurements. <footnote>

+    <title>Field Order</title>
+
+    <para>We have to distinguish between progressive and interlaced
+video. Progressive video transmits all lines of a video image
+sequentially. Interlaced video divides an image into two fields,
+containing only the odd and even lines of the image, respectively.
+Alternating the so called odd and even field are transmitted, and due
+to a small delay between fields a cathode ray TV displays the lines
+interleaved, yielding the original frame. This curious technique was
+invented because at refresh rates similar to film the image would
+fade out too quickly. Transmitting fields reduces the flicker without
+the necessity of doubling the frame rate and with it the bandwidth
+required for each channel.</para>
+
+    <para>It is important to understand a video camera does not expose
+one frame at a time, merely transmitting the frames separated into
+fields. The fields are in fact captured at two different instances in
+time. An object on screen may well move between one field and the
+next. For applications analysing motion it is of paramount importance
+to recognize which field of a frame is older, the <emphasis>temporal
+order</emphasis>.</para>
+
+    <para>When the driver provides or accepts images field by field
+rather than interleaved, it is also important applications understand
+how the fields combine to frames. We distinguish between top and
+bottom fields, the <emphasis>spatial order</emphasis>: The first line
+of the top field is the first line of an interlaced frame, the first
+line of the bottom field is the second line of that frame.</para>
+
+    <para>However because fields were captured one after the other,
+arguing whether a frame commences with the top or bottom field is
+pointless. Any two successive top and bottom, or bottom and top fields
+yield a valid frame. Only when the source was progressive to begin
+with, &eg; when transferring film to video, two fields may come from
+the same frame, creating a natural order.</para>
+
+    <para>Counter to intuition the top field is not necessarily the
+older field. Whether the older field contains the top or bottom lines
+is a convention determined by the video standard. Hence the
+distinction between temporal and spatial order of fields. The diagrams
+below should make this clearer.</para>
+
+    <para>All video capture and output devices must report the current
+field order. Some drivers may permit the selection of a different
+order, to this end applications initialize the
+<structfield>field</structfield> field of &v4l2-pix-format; before
+calling the &VIDIOC-S-FMT; ioctl. If this is not desired it should

+</para>
+		<para>Later on libv4lconvert was expanded to also be able to do
+various	video processing functions to improve webcam video quality.
+The video processing is split in to 2 parts: libv4lconvert/control and
+libv4lconvert/processing.</para>
+
+		<para>The control part is used to offer video controls which can
+be used	to control the video processing functions made available by
+	libv4lconvert/processing. These controls are stored application wide
+(until reboot) by using a persistent shared memory object.</para>
+
+		<para>libv4lconvert/processing offers the actual video
+processing functionality.</para>

+	<section>
+		<title>libv4l1</title>
+		<para>This library offers functions that can be used to quickly
+make v4l1 applications work with v4l2 devices. These functions work exactly
+like the normal open/close/etc, except that libv4l1 does full emulation of
+the v4l1 api on top of v4l2 drivers, in case of v4l1 drivers it
+will just pass calls through.</para>
+		<para>Since those functions are emulations of the old V4L1 API,
+it shouldn't be used for new applications.</para>
+	</section>
+	<section>
+		<title>libv4l2</title>
+		<para>This library should be used for all modern V4L2
+applications.</para>
+		<para>It provides handles to call V4L2 open/ioctl/close/poll
+methods. Instead of just providing the raw output of the device, it enhances
+the calls in the sense that it will use libv4lconvert to provide more video
+formats and to enhance the image quality.</para>
+		<para>In most cases, libv4l2 just passes the calls directly
+through to the v4l2 driver, intercepting the calls to

+	<para>This is commonly the native format of digital cameras,
+reflecting the arrangement of sensors on the CCD device. Only one red,
+green or blue value is given for each pixel. Missing components must
+be interpolated from neighbouring pixels. From left to right the first
+row consists of a green and blue value, the second row of a red and
+green value. This scheme repeats to the right and down for every two
+columns and rows.</para>

+	<para>This format is not commonly used. This is a planar
+version of the YUYV format. The three components are separated into
+three sub-images or planes. The Y plane is first. The Y plane has one
+byte per pixel. The Cb plane immediately follows the Y plane in
+memory. The Cb plane is half the width of the Y plane (and of the
+image). Each Cb belongs to two pixels. For example,
+Cb<subscript>0</subscript> belongs to Y'<subscript>00</subscript>,
+Y'<subscript>01</subscript>. Following the Cb plane is the Cr plane,
+just like the Cb plane.</para>
+
+	<para>If the Y plane has pad bytes after each row, then the Cr
+and Cb planes have half as many pad bytes after their rows. In other
+words, two Cx rows (including padding) is exactly as long as one Y row
+(including padding).</para>

+    <title>Standard Image Formats</title>
+
+    <para>In order to exchange images between drivers and
+applications, it is necessary to have standard image data formats
+which both sides will interpret the same way. V4L2 includes several
+such formats, and this section is intended to be an unambiguous
+specification of the standard image data formats in V4L2.</para>
+
+    <para>V4L2 drivers are not limited to these formats, however.
+Driver-specific formats are possible. In that case the application may
+depend on a codec to convert images to one of the standard formats
+when needed. But the data can still be stored and retrieved in the
+proprietary format. For example, a device may support a proprietary
+compressed format. Applications can still capture and save the data in
+the compressed format, saving much disk space, and later use a codec
+to convert the images to the X Windows screen format when the video is
+to be displayed.</para>
+
+    <para>Even so, ultimately, some standard formats are needed, so
+the V4L2 specification would not be complete without well-defined
+standard formats.</para>
+
+    <para>The V4L2 standard formats are mainly uncompressed formats. The
+pixels are always arranged in memory from left to right, and from top
+to bottom. The first byte of data in the image buffer is always for
+the leftmost pixel of the topmost row. Following that is the pixel
+immediately to its right, and so on until the end of the top row of
+pixels. Following the rightmost pixel of the row there may be zero or
+more bytes of padding to guarantee that each row of pixel data has a
+certain alignment. Following the pad bytes, if any, is data for the
+leftmost pixel of the second row from the top, and so on. The last row
+has just as many pad bytes after it as the other rows.</para>
+
+    <para>In V4L2 each format has an identifier which looks like
+<constant>PIX_FMT_XXX</constant>, defined in the <link
+linkend="videodev">videodev.h</link> header file. These identifiers
+represent <link linkend="v4l2-fourcc">four character codes</link>
+which are also listed below, however they are not the same as those
+used in the Windows world.</para>

+    <title>YUV Formats</title>
+
+    <para>YUV is the format native to TV broadcast and composite video
+signals. It separates the brightness information (Y) from the color
+information (U and V or Cb and Cr). The color information consists of
+red and blue <emphasis>color difference</emphasis> signals, this way
+the green component can be reconstructed by subtracting from the
+brightness component. See <xref linkend="colorspaces" /> for conversion
+examples. YUV was chosen because early television would only transmit
+brightness information. To add color in a way compatible with existing
+receivers a new signal carrier was added to transmit the color
+difference signals. Secondary in the YUV format the U and V components
+usually have lower resolution than the Y component. This is an analog
+video compression technique taking advantage of a property of the
+human visual system, being more sensitive to brightness
+information.</para>

+<para>Currently, most analog and digital devices have a Infrared input for remote controllers. Each manufacturer has their own type of control. It is not rare that the same manufacturer to ship different types of controls, depending on the device.</para>
+<para>Unfortunately, during several years, there weren't any effort to uniform the IR keycodes under different boards. This resulted that the same IR keyname to be mapped completely different on different IR's. Due to that, V4L2 API now specifies a standard for mapping Media keys on IR.</para>
+<para>This standard should be used by both V4L/DVB drivers and userspace applications</para>
+<para>The modules register the remote as keyboard within the linux input layer. This means that the IR key strokes will look like normal keyboard key strokes (if CONFIG_INPUT_KEYBOARD is enabled). Using the event devices (CONFIG_INPUT_EVDEV) it is possible for applications to access the remote via /dev/input/event devices.</para>

+
+    <para>For driver debugging purposes this ioctl allows test
+applications to query the driver about the chips present on the TV
+card. Regular applications must not use it. When you found a chip
+specific bug, please contact the linux-media mailing list (&v4l-ml;)
+so it can be fixed.</para>
+
+    <para>To query the driver applications must initialize the
+<structfield>match.type</structfield> and
+<structfield>match.addr</structfield> or <structfield>match.name</structfield>
+fields of a &v4l2-dbg-chip-ident;
+and call <constant>VIDIOC_DBG_G_CHIP_IDENT</constant> with a pointer to
+this structure. On success the driver stores information about the
+selected chip in the <structfield>ident</structfield> and
+<structfield>revision</structfield> fields. On failure the structure
+remains unchanged.</para>
+
+    <para>When <structfield>match.type</structfield> is
+<constant>V4L2_CHIP_MATCH_HOST</constant>,
+<structfield>match.addr</structfield> selects the nth non-&i2c; chip
+on the TV card. You can enumerate all chips by starting at zero and
+incrementing <structfield>match.addr</structfield> by one until
+<constant>VIDIOC_DBG_G_CHIP_IDENT</constant> fails with an &EINVAL;.
+The number zero always selects the host chip, &eg; the chip connected
+to the PCI or USB bus.</para>
+
+    <para>When <structfield>match.type</structfield> is
+<constant>V4L2_CHIP_MATCH_I2C_DRIVER</constant>,
+<structfield>match.name</structfield> contains the I2C driver name.
+For instance
+<constant>"saa7127"</constant> will match any chip
+supported by the saa7127 driver, regardless of its &i2c; bus address.
+When multiple chips supported by the same driver are present, the
+ioctl will return <constant>V4L2_IDENT_AMBIGUOUS</constant> in the
+<structfield>ident</structfield> field.</para>
+
+    <para>When <structfield>match.type</structfield> is
+<constant>V4L2_CHIP_MATCH_I2C_ADDR</constant>,
+<structfield>match.addr</structfield> selects a chip by its 7 bit
+&i2c; bus address.</para>
+
+    <para>When <structfield>match.type</structfield> is
+<constant>V4L2_CHIP_MATCH_AC97</constant>,
+<structfield>match.addr</structfield> selects the nth AC97 chip
+on the TV card. You can enumerate all chips by starting at zero and
+incrementing <structfield>match.addr</structfield> by one until
+<constant>VIDIOC_DBG_G_CHIP_IDENT</constant> fails with an &EINVAL;.</para>
+
+    <para>On success, the <structfield>ident</structfield> field will
+contain a chip ID from the Linux
+<filename>media/v4l2-chip-ident.h</filename> header file, and the
+<structfield>revision</structfield> field will contain a driver
+specific value, or zero if no particular revision is associated with
+this chip.</para>
+
+    <para>When the driver could not identify the selected chip,
+<structfield>ident</structfield> will contain
+<constant>V4L2_IDENT_UNKNOWN</constant>. When no chip matched
+the ioctl will succeed but the
+<structfield>ident</structfield> field will contain
+<constant>V4L2_IDENT_NONE</constant>. If multiple chips matched,
+<structfield>ident</structfield> will contain
+<constant>V4L2_IDENT_AMBIGUOUS</constant>. In all these cases the
+<structfield>revision</structfield> field remains unchanged.</para>
+
+    <para>This ioctl is optional, not all drivers may support it. It
+was introduced in Linux 2.6.21, but the API was changed to the
+one described here in 2.6.29.</para>
+
+    <para>We recommended the <application>v4l2-dbg</application>
+utility over calling this ioctl directly. It is available from the

+
+    <para>For driver debugging purposes these ioctls allow test
+applications to access hardware registers directly. Regular
+applications must not use them.</para>
+
+    <para>Since writing or even reading registers can jeopardize the
+system security, its stability and damage the hardware, both ioctls
+require superuser privileges. Additionally the Linux kernel must be
+compiled with the <constant>CONFIG_VIDEO_ADV_DEBUG</constant> option
+to enable these ioctls.</para>
+
+    <para>To write a register applications must initialize all fields
+of a &v4l2-dbg-register; and call
+<constant>VIDIOC_DBG_S_REGISTER</constant> with a pointer to this
+structure. The <structfield>match.type</structfield> and
+<structfield>match.addr</structfield> or <structfield>match.name</structfield>
+fields select a chip on the TV
+card, the <structfield>reg</structfield> field specifies a register
+number and the <structfield>val</structfield> field the value to be
+written into the register.</para>
+
+    <para>To read a register applications must initialize the
+<structfield>match.type</structfield>,
+<structfield>match.chip</structfield> or <structfield>match.name</structfield> and
+<structfield>reg</structfield> fields, and call
+<constant>VIDIOC_DBG_G_REGISTER</constant> with a pointer to this
+structure. On success the driver stores the register value in the
+<structfield>val</structfield> field. On failure the structure remains
+unchanged.</para>
+
+    <para>When <structfield>match.type</structfield> is
+<constant>V4L2_CHIP_MATCH_HOST</constant>,
+<structfield>match.addr</structfield> selects the nth non-&i2c; chip
+on the TV card.  The number zero always selects the host chip, &eg; the
+chip connected to the PCI or USB bus. You can find out which chips are
+present with the &VIDIOC-DBG-G-CHIP-IDENT; ioctl.</para>
+
+    <para>When <structfield>match.type</structfield> is
+<constant>V4L2_CHIP_MATCH_I2C_DRIVER</constant>,
+<structfield>match.name</structfield> contains the I2C driver name.
+For instance
+<constant>"saa7127"</constant> will match any chip
+supported by the saa7127 driver, regardless of its &i2c; bus address.
+When multiple chips supported by the same driver are present, the
+effect of these ioctls is undefined. Again with the
+&VIDIOC-DBG-G-CHIP-IDENT; ioctl you can find out which &i2c; chips are
+present.</para>
+
+    <para>When <structfield>match.type</structfield> is
+<constant>V4L2_CHIP_MATCH_I2C_ADDR</constant>,
+<structfield>match.addr</structfield> selects a chip by its 7 bit &i2c;
+bus address.</para>
+
+    <para>When <structfield>match.type</structfield> is
+<constant>V4L2_CHIP_MATCH_AC97</constant>,
+<structfield>match.addr</structfield> selects the nth AC97 chip
+on the TV card.</para>
+
+    <note>
+      <title>Success not guaranteed</title>
+
+      <para>Due to a flaw in the Linux &i2c; bus driver these ioctls may
+return successfully without actually reading or writing a register. To
+catch the most likely failure we recommend a &VIDIOC-DBG-G-CHIP-IDENT;
+call confirming the presence of the selected &i2c; chip.</para>
+    </note>
+
+    <para>These ioctls are optional, not all drivers may support them.
+However when a driver supports these ioctls it must also support
+&VIDIOC-DBG-G-CHIP-IDENT;. Conversely it may support
+<constant>VIDIOC_DBG_G_CHIP_IDENT</constant> but not these ioctls.</para>
+

+    <para>These ioctls control an audio/video (usually MPEG-) encoder.
+<constant>VIDIOC_ENCODER_CMD</constant> sends a command to the
+encoder, <constant>VIDIOC_TRY_ENCODER_CMD</constant> can be used to
+try a command without actually executing it.</para>
+
+    <para>To send a command applications must initialize all fields of a
+    &v4l2-encoder-cmd; and call
+    <constant>VIDIOC_ENCODER_CMD</constant> or
+    <constant>VIDIOC_TRY_ENCODER_CMD</constant> with a pointer to this
+    structure.</para>
+
+    <para>The <structfield>cmd</structfield> field must contain the
+command code. The <structfield>flags</structfield> field is currently
+only used by the STOP command and contains one bit: If the
+<constant>V4L2_ENC_CMD_STOP_AT_GOP_END</constant> flag is set,
+encoding will continue until the end of the current <wordasword>Group
+Of Pictures</wordasword>, otherwise it will stop immediately.</para>
+
+    <para>A <function>read</function>() call sends a START command to
+the encoder if it has not been started yet. After a STOP command,
+<function>read</function>() calls will read the remaining data
+buffered by the driver. When the buffer is empty,
+<function>read</function>() will return zero and the next
+<function>read</function>() call will restart the encoder.</para>
+
+    <para>A <function>close</function>() call sends an immediate STOP
+to the encoder, and all buffered data is discarded.</para>

+(&ie; width and height in pixels) that the device supports for the
+given pixel format.</para>
+    <para>The supported pixel formats can be obtained by using the
+&VIDIOC-ENUM-FMT; function.</para>
+    <para>The return value and the content of the
+<structfield>v4l2_frmsizeenum.type</structfield> field depend on the
+type of frame sizes the device supports. Here are the semantics of the
+function for the different cases:</para>

+    <itemizedlist>
+      <listitem>
+	<para><emphasis role="bold">Discrete:</emphasis> The function
+returns success if the given index value (zero-based) is valid. The
+application should increase the index by one for each call until
+<constant>EINVAL</constant> is returned. The
+<structfield>v4l2_frmsizeenum.type</structfield> field is set to
+<constant>V4L2_FRMSIZE_TYPE_DISCRETE</constant> by the driver. Of the
+union only the <structfield>discrete</structfield> member is
+valid.</para>
+      </listitem>
+      <listitem>
+	<para><emphasis role="bold">Step-wise:</emphasis> The function
+returns success if the given index value is zero and
+<constant>EINVAL</constant> for any other index value. The
+<structfield>v4l2_frmsizeenum.type</structfield> field is set to
+<constant>V4L2_FRMSIZE_TYPE_STEPWISE</constant> by the driver. Of the
+union only the <structfield>stepwise</structfield> member is
+valid.</para>
+      </listitem>
+      <listitem>
+	<para><emphasis role="bold">Continuous:</emphasis> This is a
+special case of the step-wise type above. The function returns success
+if the given index value is zero and <constant>EINVAL</constant> for
+any other index value. The
+<structfield>v4l2_frmsizeenum.type</structfield> field is set to
+<constant>V4L2_FRMSIZE_TYPE_CONTINUOUS</constant> by the driver. Of
+the union only the <structfield>stepwise</structfield> member is valid
+and the <structfield>step_width</structfield> and
+<structfield>step_height</structfield> values are set to 1.</para>
+      </listitem>
+    </itemizedlist>
+
+    <para>When the application calls the function with index zero, it
+must check the <structfield>type</structfield> field to determine the
+type of frame size enumeration the device supports. Only for the
+<constant>V4L2_FRMSIZE_TYPE_DISCRETE</constant> type does it make
+sense to increase the index value to receive more frame sizes.</para>
+    <para>Note that the order in which the frame sizes are returned
+has no special meaning. In particular does it not say anything about
+potential default format sizes.</para>
+    <para>Applications can assume that the enumeration data does not
+change without any interaction from the application itself. This means
+that the enumeration data is consistent if the application does not
+perform any other ioctl calls while it runs the frame size
+enumeration.</para>

+
+    <para>These ioctls allow the caller to get or set multiple
+controls atomically. Control IDs are grouped into control classes (see
+<xref linkend="ctrl-class" />) and all controls in the control array
+must belong to the same control class.</para>
+
+    <para>Applications must always fill in the
+<structfield>count</structfield>,
+<structfield>ctrl_class</structfield>,
+<structfield>controls</structfield> and
+<structfield>reserved</structfield> fields of &v4l2-ext-controls;, and
+initialize the &v4l2-ext-control; array pointed to by the
+<structfield>controls</structfield> fields.</para>
+
+    <para>To get the current value of a set of controls applications
+initialize the <structfield>id</structfield>,
+<structfield>size</structfield> and <structfield>reserved2</structfield> fields
+of each &v4l2-ext-control; and call the
+<constant>VIDIOC_G_EXT_CTRLS</constant> ioctl. String controls controls
+must also set the <structfield>string</structfield> field.</para>
+
+    <para>If the <structfield>size</structfield> is too small to
+receive the control result (only relevant for pointer-type controls
+like strings), then the driver will set <structfield>size</structfield>
+to a valid value and return an &ENOSPC;. You should re-allocate the
+string memory to this new size and try again. It is possible that the
+same issue occurs again if the string has grown in the meantime. It is
+recommended to call &VIDIOC-QUERYCTRL; first and use
+<structfield>maximum</structfield>+1 as the new <structfield>size</structfield>
+value. It is guaranteed that that is sufficient memory.
+</para>
+
+    <para>To change the value of a set of controls applications
+initialize the <structfield>id</structfield>, <structfield>size</structfield>,
+<structfield>reserved2</structfield> and
+<structfield>value/string</structfield> fields of each &v4l2-ext-control; and
+call the <constant>VIDIOC_S_EXT_CTRLS</constant> ioctl. The controls
+will only be set if <emphasis>all</emphasis> control values are
+valid.</para>
+
+    <para>To check if a set of controls have correct values applications
+initialize the <structfield>id</structfield>, <structfield>size</structfield>,
+<structfield>reserved2</structfield> and
+<structfield>value/string</structfield> fields of each &v4l2-ext-control; and
+call the <constant>VIDIOC_TRY_EXT_CTRLS</constant> ioctl. It is up to
+the driver whether wrong values are automatically adjusted to a valid
+value or if an error is returned.</para>
+
+    <para>When the <structfield>id</structfield> or
+<structfield>ctrl_class</structfield> is invalid drivers return an
+&EINVAL;. When the value is out of bounds drivers can choose to take
+the closest valid value or return an &ERANGE;, whatever seems more
+appropriate. In the first case the new value is set in
+&v4l2-ext-control;.</para>
+
+    <para>The driver will only set/get these controls if all control
+values are correct. This prevents the situation where only some of the
+controls were set/get. Only low-level errors (&eg; a failed i2c
+command) can still cause this situation.</para>

+
+    <para>Applications can use the <constant>VIDIOC_G_FBUF</constant> and
+<constant>VIDIOC_S_FBUF</constant> ioctl to get and set the
+framebuffer parameters for a <link linkend="overlay">Video
+Overlay</link> or <link linkend="osd">Video Output Overlay</link>
+(OSD). The type of overlay is implied by the device type (capture or
+output device) and can be determined with the &VIDIOC-QUERYCAP; ioctl.
+One <filename>/dev/videoN</filename> device must not support both
+kinds of overlay.</para>
+
+    <para>The V4L2 API distinguishes destructive and non-destructive
+overlays. A destructive overlay copies captured video images into the
+video memory of a graphics card. A non-destructive overlay blends
+video images into a VGA signal or graphics into a video signal.
+<wordasword>Video Output Overlays</wordasword> are always
+non-destructive.</para>
+
+    <para>To get the current parameters applications call the
+<constant>VIDIOC_G_FBUF</constant> ioctl with a pointer to a
+<structname>v4l2_framebuffer</structname> structure. The driver fills
+all fields of the structure or returns an &EINVAL; when overlays are
+not supported.</para>
+
+    <para>To set the parameters for a <wordasword>Video Output
+Overlay</wordasword>, applications must initialize the
+<structfield>flags</structfield> field of a struct
+<structname>v4l2_framebuffer</structname>. Since the framebuffer is
+implemented on the TV card all other parameters are determined by the
+driver. When an application calls <constant>VIDIOC_S_FBUF</constant>
+with a pointer to this structure, the driver prepares for the overlay
+and returns the framebuffer parameters as
+<constant>VIDIOC_G_FBUF</constant> does, or it returns an error
+code.</para>
+
+    <para>To set the parameters for a <wordasword>non-destructive
+Video Overlay</wordasword>, applications must initialize the
+<structfield>flags</structfield> field, the
+<structfield>fmt</structfield> substructure, and call
+<constant>VIDIOC_S_FBUF</constant>. Again the driver prepares for the
+overlay and returns the framebuffer parameters as
+<constant>VIDIOC_G_FBUF</constant> does, or it returns an error
+code.</para>
+
+    <para>For a <wordasword>destructive Video Overlay</wordasword>
+applications must additionally provide a
+<structfield>base</structfield> address. Setting up a DMA to a
+random memory location can jeopardize the system security, its
+stability or even damage the hardware, therefore only the superuser
+can set the parameters for a destructive video overlay.</para>

+    <title>Description</title>
+
+    <para>These ioctls are used to negotiate the format of data
+(typically image format) exchanged between driver and
+application.</para>
+
+    <para>To query the current parameters applications set the
+<structfield>type</structfield> field of a struct
+<structname>v4l2_format</structname> to the respective buffer (stream)
+type. For example video capture devices use
+<constant>V4L2_BUF_TYPE_VIDEO_CAPTURE</constant>. When the application
+calls the <constant>VIDIOC_G_FMT</constant> ioctl with a pointer to
+this structure the driver fills the respective member of the
+<structfield>fmt</structfield> union. In case of video capture devices
+that is the &v4l2-pix-format; <structfield>pix</structfield> member.
+When the requested buffer type is not supported drivers return an
+&EINVAL;.</para>
+
+    <para>To change the current format parameters applications
+initialize the <structfield>type</structfield> field and all
+fields of the respective <structfield>fmt</structfield>
+union member. For details see the documentation of the various devices
+types in <xref linkend="devices" />. Good practice is to query the
+current parameters first, and to
+modify only those parameters not suitable for the application. When
+the application calls the <constant>VIDIOC_S_FMT</constant> ioctl
+with a pointer to a <structname>v4l2_format</structname> structure
+the driver checks
+and adjusts the parameters against hardware abilities. Drivers
+should not return an error code unless the input is ambiguous, this is
+a mechanism to fathom device capabilities and to approach parameters
+acceptable for both the application and driver. On success the driver
+may program the hardware, allocate resources and generally prepare for
+data exchange.
+Finally the <constant>VIDIOC_S_FMT</constant> ioctl returns the
+current format parameters as <constant>VIDIOC_G_FMT</constant> does.
+Very simple, inflexible devices may even ignore all input and always
+return the default parameters. However all V4L2 devices exchanging
+data with the application must implement the
+<constant>VIDIOC_G_FMT</constant> and
+<constant>VIDIOC_S_FMT</constant> ioctl. When the requested buffer
+type is not supported drivers return an &EINVAL; on a
+<constant>VIDIOC_S_FMT</constant> attempt. When I/O is already in
+progress or the resource is not available for other reasons drivers
+return the &EBUSY;.</para>
+
+    <para>The <constant>VIDIOC_TRY_FMT</constant> ioctl is equivalent
+to <constant>VIDIOC_S_FMT</constant> with one exception: it does not
+change driver state. It can also be called at any time, never
+returning <errorcode>EBUSY</errorcode>. This function is provided to
+negotiate parameters, to learn about hardware limitations, without
+disabling I/O or possibly time consuming hardware preparations.
+Although strongly recommended drivers are not required to implement
+this ioctl.</para>

+    <para>jpeg_markers describes whether the huffman tables,

+These define how the JPEG field is encoded. If you omit them,

+
+    <para>The current video standard determines a nominal number of
+frames per second. If less than this number of frames is to be
+captured or output, applications can request frame skipping or
+duplicating on the driver side. This is especially useful when using
+the <function>read()</function> or <function>write()</function>, which
+are not augmented by timestamps or sequence counters, and to avoid
+unneccessary data copying.</para>
+
+    <para>Further these ioctls can be used to determine the number of
+buffers used internally by a driver in read/write mode. For
+implications see the section discussing the &func-read;
+function.</para>
+
+    <para>To get and set the streaming parameters applications call
+the <constant>VIDIOC_G_PARM</constant> and
+<constant>VIDIOC_S_PARM</constant> ioctl, respectively. They take a
+pointer to a struct <structname>v4l2_streamparm</structname> which
+contains a union holding separate parameters for input and output
+devices.</para>

+allocated with this ioctl before they can be mapped into the
+application's address space. User buffers are allocated by
+applications themselves, and this ioctl is merely used to switch the
+driver into user pointer I/O mode.</para>
+
+    <para>To allocate device buffers applications initialize three
+fields of a <structname>v4l2_requestbuffers</structname> structure.
+They set the <structfield>type</structfield> field to the respective
+stream or buffer type, the <structfield>count</structfield> field to
+the desired number of buffers, and <structfield>memory</structfield>
+must be set to <constant>V4L2_MEMORY_MMAP</constant>. When the ioctl
+is called with a pointer to this structure the driver attempts to
+allocate the requested number of buffers and stores the actual number
+allocated in the <structfield>count</structfield> field. It can be
+smaller than the number requested, even zero, when the driver runs out
+of free memory. A larger number is possible when the driver requires
+more buffers to function correctly.<footnote>
+	<para>For example video output requires at least two buffers,
+one displayed and one filled by the application.</para>

+returns an &EINVAL;.</para>

+again to change the number of buffers, however this cannot succeed
+when any buffers are still mapped. A <structfield>count</structfield>
+value of zero frees all buffers, after aborting or finishing any DMA
+in progress, an implicit &VIDIOC-STREAMOFF;. <!-- mhs: I see no
+reason why munmap()ping one or even all buffers must imply
+streamoff.--></para>
+
+    <para>To negotiate user pointer I/O, applications initialize only
+the <structfield>type</structfield> field and set
+<structfield>memory</structfield> to
+<constant>V4L2_MEMORY_USERPTR</constant>. When the ioctl is called

+or output process during streaming (<link linkend="mmap">memory
+mapping</link> or <link linkend="userp">user pointer</link>) I/O.</para>
+
+    <para>Specifically the capture hardware is disabled and no input
+buffers are filled (if there are any empty buffers in the incoming
+queue) until <constant>VIDIOC_STREAMON</constant> has been called.
+Accordingly the output hardware is disabled, no video signal is
+produced until <constant>VIDIOC_STREAMON</constant> has been called.
+The ioctl will succeed only when at least one output buffer is in the
+incoming queue.</para>
+
+    <para>The <constant>VIDIOC_STREAMOFF</constant> ioctl, apart of
+aborting or finishing any DMA in progress, unlocks any user pointer
+buffers locked in physical memory, and it removes all buffers from the
+incoming and outgoing queues. That means all images captured but not
+dequeued yet will be lost, likewise all images enqueued for output but
+not transmitted yet. I/O returns to the same state as after calling
+&VIDIOC-REQBUFS; and can be restarted accordingly.</para>
+
+    <para>Both ioctls take a pointer to an integer, the desired buffer or
+stream type. This is the same as &v4l2-requestbuffers;

Subject: V4L/DVB (12861): tda18271: add support for additional low-power
 standby modes

By default, the driver enters standby mode with slave tuner output
loop thru enabled and xtal oscillator on.

Not all designs require that slave tuner output loop thru and
xtal oscillator remain active while in standby mode, so two
additional standby modes have been added:

- standby mode with xtal oscillator on (loop thru off)

- total power off

Subject: V4L/DVB (12864): tda18271: change output feature configuration to a
 bitmask

For better readability, treat the low power standby mode configuration
as an output option feature configuration, and change it to a bitmask.

If left unconfigured, all features will remain enabled, just as the
default configuration was before these changes were introduced.

Subject: V4L/DVB (12867): tda18271: ensure that configuration options are set
 for multiple instances

For the case of multiple tuner instances, ensure that non-default
configuration options are saved into the driver's state.

This resolves an issue where a configuration option may not be
carried into the driver if the analog side of a hybrid driver
initializes before the digital side.

The MSI GX700 is a tricky machine to support. Some revisions do need the sensor flipped, but not all.
Add another quirk, distinguished by its BIOS date.

i2c-kbd-i2c allows a bridge driver to pass information about IR configuration,
but uses a "void *" to pass along what is essentially constant data.  This
change casts a const * to a void * to remove the warning.

Subject: DocBook/media: renamed xml documents to tmpl

DocBook makefile expects that the documents to be in tmpl extension,
since it has some preprocessing that it is done on it. This preprocessing
is not needed currently, but, as it removes the xml versions, we're
forced to rename anyway.

Subject: DocBook: Don't use graphics callouts

By default, when a callout is used, DocBook will try to use
a graphics image for callouts. This requires that the graphics
to be copied to the documentation directory. As this is not
done, use the text callouts: (1), (2), ...

Subject: V4L/DVB (12892): DVB-API: add support for ISDB-T and ISDB-Tsb
 (version 5.1)

This patch increments the DVB-API to version 5.1 in order to reflect the addition of ISDB-T and ISDB-Tsb on Linux' DVB-API.

Changes in detail:
- added a small document to describe how to use the API to tune to an ISDB-T or ISDB-Tsb channel
- added necessary fields to dtv_frontend_cache
- added a smarter clear-cache function which resets all fields of the dtv_frontend_cache
- added a TRANSMISSION_MODE_4K to fe_transmit_mode_t

Subject: V4L/DVB (12902): Documentation: synchronize documentation for
 Technisat cards

The patch does the following:

a. it synchronizes /Documentation/dvb/technisat.txt to the current kernel
design
b. it syncs Trent Piepho' s latest changes to the flexcop driver concept:
implementation of the dvb pll library for some cards that need it

Subject: V4L/DVB (12923): SAA7164: Add support for the NXP SAA7164 silicon

This patch adds support for all of the known shipping Hauppauge HVR-2200
and HVR-2250 boards. Digital TV ATSC/QAM and DVB-T is enabled at this
time. Both tuners are supported.

Volatiles and typedefs need rework, the rest is coding style compliant.

Subject: V4L/DVB (12938): SAA7164: Increase the firmware command timeout to
 avoid firmware errors.

The firmware typically responds in < 50ms and, via the interrupts and
deferred work queue the caller (blocked in the driver) is signalled very
efficiently. In a highly stressed system this can take many multiples
of seconds. So, we need a larger maximum timeout for busy systems.

Subject: V4L/DVB (12940): SAA7164: IRQ / message timeout related change

In some cases we're seeing large timeouts on commands. I'm changing the
implementation so that the deferred worker checks the PCI bus for
any messages and signals the waiting caller accordingly. The previous
mechanism was too unreliable.

Subject: V4L/DVB (12942): SAA7164: HVR2250 changes related to attach time
 tuner configuration

Ensure that by default all tuners are set correctly to master/slave mode.
For all HVR2250's, ensure slave based tuners are caliberated during attach
to avoid locking problems on tuner# above channel 91.

HVR2200 tuner attach time to be reviewed in a future patch.

The VIDIOC_G_STD ioctl may not be present in the case of radio receivers.
In that case G_STD will return an error. The v4l1-compat layer should not
attempt to propagate that error to the caller, instead it should be
ignored.

Subject: V4L/DVB (12956): Fix gpio mutex in NetUP Dual DVB-S2 CI card.

The card uses the same cx23885 gpio lines for two adapters.
In case of there is several cards in system we must implement
gpio mutex per cx23885 chip.

 <para>Unfortunately, for several years, there was no effort to create uniform IR keycodes for

-different IR devices. This resulted that the same IR keyname to be mapped completely different on 
+different IR devices. This resulted that the same IR keyname to be mapped completely different on

 <para>This standard should be used by both V4L/DVB drivers and userspace applications</para>
 <para>The modules register the remote as keyboard within the linux input layer. This means that the IR key strokes will look like normal keyboard key strokes (if CONFIG_INPUT_KEYBOARD is enabled). Using the event devices (CONFIG_INPUT_EVDEV) it is possible for applications to access the remote via /dev/input/event devices.</para>

Subject: V4L/DVB (12248): v4l: vpfe capture bridge driver for DM355 and DM6446

This the vpfe capture bridge driver for doing video
capture on DM355 and DM6446 evms. The ccdc hw modules register with the
driver and are used for configuring the CCD Controller for a specific
decoder interface. The driver also registers the sub devices required
for a specific evm. More than one sub devices can be registered.
This allows driver to switch dynamically to capture video from
any sub device that is registered. Currently only one sub device
(tvp5146) is supported. But in future this driver is expected
to do capture from sensor devices such as Micron's MT9T001, MT9T031
and MT9P031 etc. The driver currently supports MMAP based IO.

+ *
+ * Driver name : VPFE Capture driver
+ *    VPFE Capture driver allows applications to capture and stream video
+ *    frames on DaVinci SoCs (DM6446, DM355 etc) from a YUV source such as
+ *    TVP5146 or  Raw Bayer RGB image data from an image sensor
+ *    such as Microns' MT9T001, MT9T031 etc.
+ *
+ *    These SoCs have, in common, a Video Processing Subsystem (VPSS) that
+ *    consists of a Video Processing Front End (VPFE) for capturing
+ *    video/raw image data and Video Processing Back End (VPBE) for displaying
+ *    YUV data through an in-built analog encoder or Digital LCD port. This
+ *    driver is for capture through VPFE. A typical EVM using these SoCs have
+ *    following high level configuration.
+ *
+ *
+ *    decoder(TVP5146/		YUV/
+ * 	     MT9T001)   -->  Raw Bayer RGB ---> MUX -> VPFE (CCDC/ISIF)
+ *    				data input              |      |
+ *							V      |
+ *						      SDRAM    |
+ *							       V
+ *							   Image Processor
+ *							       |
+ *							       V
+ *							     SDRAM
+ *    The data flow happens from a decoder connected to the VPFE over a
+ *    YUV embedded (BT.656/BT.1120) or separate sync or raw bayer rgb interface
+ *    and to the input of VPFE through an optional MUX (if more inputs are
+ *    to be interfaced on the EVM). The input data is first passed through
+ *    CCDC (CCD Controller, a.k.a Image Sensor Interface, ISIF). The CCDC
+ *    does very little or no processing on YUV data and does pre-process Raw
+ *    Bayer RGB data through modules such as Defect Pixel Correction (DFC)
+ *    Color Space Conversion (CSC), data gain/offset etc. After this, data
+ *    can be written to SDRAM or can be connected to the image processing
+ *    block such as IPIPE (on DM355 only).
+ *
+ *    Features supported
+ *  		- MMAP IO
+ *		- Capture using TVP5146 over BT.656
+ *		- support for interfacing decoders using sub device model
+ *		- Work with DM355 or DM6446 CCDC to do Raw Bayer RGB/YUV
+ *		  data capture to SDRAM.
+ *    TODO list
+ *		- Support multiple REQBUF after open
+ *		- Support for de-allocating buffers through REQBUF
+ *		- Support for Raw Bayer RGB capture
+ *		- Support for chaining Image Processor
+ *		- Support for static allocation of buffers
+ *		- Support for USERPTR IO
+ *		- Support for STREAMON before QBUF
+ *		- Support for control ioctls

+ * CCDC hardware module for DM355
+ * ------------------------------
+ *
+ * This module is for configuring DM355 CCD controller of VPFE to capture
+ * Raw yuv or Bayer RGB data from a decoder. CCDC has several modules
+ * such as Defect Pixel Correction, Color Space Conversion etc to
+ * pre-process the Bayer RGB data, before writing it to SDRAM. This
+ * module also allows application to configure individual
+ * module parameters through VPFE_CMD_S_CCDC_RAW_PARAMS IOCTL.
+ * To do so, application include dm355_ccdc.h and vpfe_capture.h header
+ * files. The setparams() API is called by vpfe_capture driver
+ * to configure module parameters
+ *
+ * TODO: 1) Raw bayer parameter settings and bayer capture
+ * 	 2) Split module parameter structure to module specific ioctl structs
+ *	 3) add support for lense shading correction
+ *	 4) investigate if enum used for user space type definition
+ * 	    to be replaced by #defines or integer

+ * CCDC hardware module for DM6446
+ * ------------------------------
+ *
+ * This module is for configuring CCD controller of DM6446 VPFE to capture
+ * Raw yuv or Bayer RGB data from a decoder. CCDC has several modules
+ * such as Defect Pixel Correction, Color Space Conversion etc to
+ * pre-process the Raw Bayer RGB data, before writing it to SDRAM. This
+ * module also allows application to configure individual
+ * module parameters through VPFE_CMD_S_CCDC_RAW_PARAMS IOCTL.
+ * To do so, application includes dm644x_ccdc.h and vpfe_capture.h header
+ * files.  The setparams() API is called by vpfe_capture driver
+ * to configure module parameters. This file is named DM644x so that other
+ * variants such DM6443 may be supported using the same module.
+ *
+ * TODO: Test Raw bayer parameter settings and bayer capture
+ * 	 Split module parameter structure to module specific ioctl structs
+ * 	 investigate if enum used for user space type definition
+ * 	 to be replaced by #defines or integer

Subject: V4L/DVB (12253): v4l: common vpss module for video drivers

This is a new module added for vpss library functions that are
used for configuring vpss system module. All video drivers will
include vpss.h header file and call functions defined in this
module to configure vpss system module.

Subject: V4L/DVB (12504): soc-camera: prepare soc_camera_platform.c and its
 users for conversion

soc_camera_platform.c is only used by y SuperH ap325rxa board. This patch
converts soc_camera_platform.c and its users for the soc-camera platform-
device conversion and also extends soc-camera core to handle non-I2C cameras.

Subject: V4L/DVB (12505): soc_camera_platform: pass device pointer from
 soc-camera core on .add_device()

Add a struct device pointer to struct soc_camera_platform_info and let the user
(ap325rxa) pass it down to soc_camera_platform.c in its .add_device() method.

Subject: V4L/DVB (12506): soc-camera: convert to platform device

Convert soc-camera core and all drivers to platform device API. We already
converted platforms to register a platform device for each soc-camera client,
now we remove the compatibility code and switch completely to the new scheme.
This is a preparatory step for the v4l2-subdev conversion.

Subject: V4L/DVB (12510): soc-camera: (partially) convert to v4l2-(sub)dev API

Convert the soc-camera framework to use the v4l2-(sub)dev API. Start using
v4l2-subdev operations. Only a part of the interface between the
soc_camera core, soc_camera host drivers on one side and soc_camera device
drivers on the other side is replaced so far. The rest of the interface
will be replaced in incremental steps, and will require extensions and,
possibly, modifications to the v4l2-subdev code.

Subject: V4L/DVB (12511): V4L2: add a new V4L2_CID_BAND_STOP_FILTER integer
 control

Add a new V4L2_CID_BAND_STOP_FILTER integer control, which either switches the
band-stop filter off, or sets it to a certain strength.

1. soc-camera always requests a valid rectangle, when calling .s_fmt(), no need
to check and adjust
2. in .s_crop(), if the rectangle exceeds sensor limits, push it to the
respective border instead of centering
3. take into account left and top borders when checking

Subject: V4L/DVB (12518): ov772x: S_CROP must return actually configured
 geometry

V4L2 drivers are allowed to configure a geometry different than what has been
requested by the user with S_CROP, but then they have to adjust the input
rectangle accordingly. Fix ov772x to comply with this requirement.

Subject: V4L/DVB (12519): soc-camera: put pixel format initialisation back in
 probe, add .put_formats()

The move of format translation initialisation into soc_camera_open() was
temporary for the soc-camera as platform driver intermediate step, put it back
into soc_camera_probe(). Also add a .put_formats() method to
soc_camera_host_ops to free any resources host driver might have allocated in
.get_formats().

Subject: V4L/DVB (12520): sh-mobile-ceu-camera: do not wait for interrupt when
 releasing buffers

Patch

[PATCH] video: use videobuf_waiton() in sh_mobile_ceu free_buffer()

was not quite correct. It closed a race, but introduced a potential
lock-up, if for some reason an interrupt does not come. This has been
observed in tests with tw9910. This patch safely dequeues buffers without
waiting for their completion. It also moves a buffer state assignment
under a spinlock to make it atomic with queuing of the buffer.

Subject: V4L/DVB (12522): sh-mobile-ceu-camera: implement host-side cropping

Not all video capture devices can configure arbitrary cropping, whereas the
CEU module on SuperH CPUs can crop with pixel precision. However, we want to
use camera cropping if possible to save bandwidth and increase the frame-rate.
This patch verifies whether the camera managed to crop exactly the requested
rectangle, and if not, uses host-side cropping. To be able to crop on CEU we
have to preserve camera rectangle too, for which the host_priv member in
struct soc_camera_device is used. We now allocate memory dynamically, thus we
have to use the .put_formats() method from struct soc_camera_host_ops to free
it.

Subject: V4L/DVB (12525): soc-camera: prohibit geometry change with
 initialised buffers

Prohibit S_FMT and S_CROP with a different window width or height after video
buffer initialisation. This simplifies the work to be done in specific host and
client drivers, and it doesn't seem to make much sense to allow these changes.
We do however allow S_CROP with equal width and height to just move the window,
this doesn't affect video buffer management and is usually easy enough to
implement.

Use host-side image scaling when the client fails to set the requested format.
We also have to take scaling into account when performing host-side cropping.
Similar to cropping we try to use client-side scaling as much as possible to
preserve bus bandwidth and optimise the frame-rate.

video operations. Also extend non-i2c drivers to also hold a pointer to their
v4l2-subdev instance in control device driver-data, i.e., in
dev_get_drvdata((struct device *)to_soc_camera_control(icd))

From: Guennadi Liakhovetski <g.liakhovetski@gmx.de>
Date: Tue, 25 Aug 2009 11:46:59 -0300
Subject: V4L/DVB (12530): soc-camera: switch to using v4l2_subdev_call()

Use v4l2_subdev_call() instead of v4l2_device_call_until_err() in all host
drivers and in soc-camera core.

Subject: V4L/DVB (12534): soc-camera: V4L2 API compliant scaling (S_FMT) and
 cropping (S_CROP)

The initial soc-camera scaling and cropping implementation turned out to be
incompliant with the V4L2 API, e.g., it expected the user to specify cropping
in output window pixels, instead of input window pixels. This patch converts
the soc-camera core and all drivers to comply with the standard.

 struct soc_camera_device also links to an array of struct soc_camera_data_format,
 listing pixel formats, supported by the camera.
 
+VIDIOC_S_CROP and VIDIOC_S_FMT behaviour
+----------------------------------------
+
+Above user ioctls modify image geometry as follows:
+
+VIDIOC_S_CROP: sets location and sizes of the sensor window. Unit is one sensor
+pixel. Changing sensor window sizes preserves any scaling factors, therefore
+user window sizes change as well.
+
+VIDIOC_S_FMT: sets user window. Should preserve previously set sensor window as
+much as possible by modifying scaling factors. If the sensor window cannot be
+preserved precisely, it may be changed too.
+
+In soc-camera there are two locations, where scaling and cropping can taks
+place: in the camera driver and in the host driver. User ioctls are first passed
+to the host driver, which then generally passes them down to the camera driver.
+It is more efficient to perform scaling and cropping in the camera driver to
+save camera bus bandwidth and maximise the framerate. However, if the camera
+driver failed to set the required parameters with sufficient precision, the host
+driver may decide to also use its own scaling and cropping to fulfill the user's
+request.
+
+Camera drivers are interfaced to the soc-camera core and to host drivers over
+the v4l2-subdev API, which is completely functional, it doesn't pass any data.
+Therefore all camera drivers shall reply to .g_fmt() requests with their current
+output geometry. This is necessary to correctly configure the camera bus.
+.s_fmt() and .try_fmt() have to be implemented too. Sensor window and scaling
+factors have to be maintained by camera drivers internally. According to the
+V4L2 API all capture drivers must support the VIDIOC_CROPCAP ioctl, hence we
+rely on camera drivers implementing .cropcap(). If the camera driver does not
+support cropping, it may choose to not implement .s_crop(), but to enable
+cropping support by the camera host driver at least the .g_crop method must be
+implemented.
+
+User window geometry is kept in .user_width and .user_height fields in struct
+soc_camera_device and used by the soc-camera core and host drivers. The core
+updates these fields upon successful completion of a .s_fmt() call, but if these
+fields change elsewhere, e.g., during .s_crop() processing, the host driver is
+responsible for updating them.

Subject: V4L/DVB (12535): soc-camera: remove .init() and .release() methods
 from struct soc_camera_ops

Remove unneeded soc-camera operations, this also makes the soc-camera API to
v4l2 subdevices thinner.

Subject: V4L/DVB (12536): soc-camera: remove .gain and .exposure struct
 soc_camera_device members

This makes the soc-camera interface for V4L2 subdevices thinner yet. Handle
gain and exposure internally in each driver just like all other controls.

Subject: V4L/DVB (12580): soc-camera: remove now unneeded subdevice group ID
 assignments

Since we are not using v4l2_device_call_* calls any more, we don't need to
initialise subdevice .grp_id any more. This also fixes compiler warnings on
64-bit platforms.

Subject: V4L/DVB (12540): v4l: simplify v4l2_i2c_new_subdev and friends

Rewrite v4l2_i2c_new_subdev as a simplified version of v4l2_i2c_new_subdev_cfg
and remove v4l2_i2c_new_probed_subdev and v4l2_i2c_new_probed_subdev_addr.

This simplifies this API substantially.

Subject: V4L/DVB (12541): v4l: remove video_register_device_index

video_register_device_index is never actually called, instead the
stream index number is always calculated automatically.

This patch removes this function and simplifies the internal get_index
function since that can now always just return the first free index.

Subject: V4L/DVB (12722): v4l2-dev: replace 'kernel number' by 'device node
 number'.

The term 'kernel number' is very vague, so replace it with the somewhat more
descriptive term 'device node number'.

In one place the local variable 'nr' was used to create the device node number
of the new device name. This has been replaced with the vdev->num field to
more clearly mark this as being the device node number and not the minor
number.

Subject: V4L/DVB (12724): v4l2-dev: add simple wrapper functions around the

There are some subtle differences in the way the devnode numbers are
handled depending on whether the FIXED_MINOR_RANGES config option is
set. Add some simple wrapper functions to handle that correctly.

 The last argument gives you a certain amount of control over the device

+device node number used (i.e. the X in videoX). Normally you will pass -1
+to let the v4l2 framework pick the first free number. But sometimes users
+want to select a specific node number. It is common that drivers allow
+the user to select a specific device node number through a driver module
+option. That number is then passed to this function and video_register_device
+will attempt to select that device node number. If that number was already
+in use, then the next free device node number will be selected and it
+will send a warning to the kernel log.
+
+Another use-case is if a driver creates many devices. In that case it can
+be useful to place different video devices in separate ranges. For example,
+video capture devices start at 0, video output devices start at 16.
 So you can use the last argument to specify a minimum device node number
 and the v4l2 framework will try to pick the first free number that is equal
 or higher to what you passed. If that fails, then it will just pick the
 first free number.
 
+Since in this case you do not care about a warning about not being able
+to select the specified device node number, you can call the function
+video_register_device_no_warn() instead.
+
 Whenever a device node is created some attributes are also created for you.
 If you look in /sys/class/video4linux you see the devices. Go into e.g.
 video0 and you will see 'name' and 'index' attributes. The 'name' attribute

v4l2_i2c_new_probed_subdev() so that platform data can be added for subdevice
configuration for polarities.

This has incorporated comments against version v0 of the patch series.

Subject: V4L/DVB (12906c): V4L : vpif capture driver for DM6467

This is the vpif capture bridge driver for DM6467.  This video
supports two video channels each having a tvp5147 device at
the input. This allows simultaneous capture of NTSC/PAL video
in each of this channel. Both MMAP and USERPTR io mechanism
are supported. Currently buffer allocation happens at REQBUF
ioctl request. Since USERPTR IO is supported, this is not an
issue since user applications can allocate buffers and pass
the user space address to the driver. Following are TODOs :-
	1) Adding support for allocation of buffers at init
	2) VBI/HBI data service

This has incorporated comments received against version v0
of the patch series.

From d28a6df608fa4fade5e1d7e22d1be652a71412e0 Mon Sep 17 00:00:00 2001
From: Muralidharan Karicheri <m-karicheri2@ti.com>
Date: Wed, 16 Sep 2009 14:31:20 -0300
Subject: V4L/DVB (12906d): V4L : vpif updates for DM6467 vpif capture driver

Following changes done for vpif driver to support vpif capture:-
	1) Current version of display driver defined vpif register
	   space as part for vpif display platform driver resource
	   This is not correct since vpif is common across capture
	   and display drivers. So the resource iomap function is
	   moved to this module
	2) Since there are common registers, a spinlock is added for
	   mutual exclusion.

This has incorporated comments against version v0 of the patch series

Resending to merge to V4L linux-next

Subject: V4L/DVB (12997): Add the DTV_ISDB_TS_ID property for ISDB_S

In ISDB-S, time-devision duplex is used to multiplexing several waves
in the same frequency. Each wave is identified by its own transport
stream ID, or TS ID. We need to provide some way to specify this ID
from user applications to handle ISDB-S frontends.

This code has been tested with the Earthsoft PT1 driver.

Subject: V4L/DVB (12999): Add a driver for Earthsoft PT1

Add a driver for Earthsoft PT1

Eearthsoft PT1 is a PCI card for Japanese broadcasting with two ISDB-S
and ISDB-T demodulators.

This card has neither MPEG decoder nor conditional access module
onboard. It transmits only compressed and possibly encrypted MPEG data
over the PCI bus, so you need an external software decoder and a
decrypter to watch TV on your computer.

This driver is originally developed by Tomoaki Ishikawa
<tomy@users.sourceforge.jp> by reverse engineering.

From 5eca4823ea8f99a7109779f68cedb00535aa6834 Mon Sep 17 00:00:00 2001
From: Akihiro Tsukada <tskd2@yahoo.co.jp>

Subject: V4L/DVB (13000): add driver for 774 Friio White USB ISDB-T receiver

This patch adds driver for 774 Friio White, ISDB-T USB receiver

Friio White is an USB 2.0 ISDB-T receiver. (http://www.friio.com/)
The device has a GL861 chip and a Comtech JDVBT90502 canned tuner module.
This driver ignores all the frontend_parameters except frequency,
as ISDB-T shares the same parameter configuration across the country
and thus the device can work like an intelligent one.

As this device does not include a CAM nor hardware descrambling feature,
the driver passes through scrambled TS streams.

There is Friio Black, a variant for ISDB-S, which shares the same USB
Vendor/Product ID with White, but it is not supported in this driver.
They should be identified in the initialization sequence,
but this feature is not tested.

Subject: V4L/DVB (13001): Key filter for BeholdTV cards.

When fast push-pull button of remote control we can received incorrect
key code 0x00. Key information from IR decoder has ID of remote control 2 bytes,
byte of key code and byte of mirror key code.
Correct data
0x86 0x6B 0x00 0xFF

Wrong data
0x86 0x6B 0x00 0x00

This patch added additional test of mirror byte for filtering.

Date: Fri, 18 Sep 2009 20:44:37 -0300
Subject: V4L/DVB (13002): Adds support for Zolid Hybrid PCI card:

http://linuxtv.org/wiki/index.php/Zolid_Hybrid_TV_Tuner

test status analog (PAL-B):
- Sometimes picture is noisy, but it becomes crystal clear after
  switching between channels. (happens for example at 687.25 Mhz)
- On a lower frequency (511.25 Mhz) the picture is always sharp, but
  lacks colour.
- No sound problems.
- radio untested.

Digital:
- DVB-T/H stream reception works.
- Would expect to see some more channels in the higher frequency region.

Overall is the impression that sensitivity still needs improvement
both in analog and digital modes.

Initialize image size before it's used to initialize exposure.
Work around lack of exposure set hardware latch with a sequence of
register writes in a single I2C command packet.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Due to rounding and clipping, exposure and gain settings do not map to
unique register values.  Rather than read the registers and report gain
and exposure that may be different than the values that were set, just
cache the latest values that were set and report them.  Reduce exposure
range from 0-65535 to 0-255 so libv4l's autogain doesn't take forever.
Remove vestiges of driver signal processing that is now handled by
libv4l.

Subject: thinkpad-acpi: don't ask about brightness_mode for fw. 1V and 1R

X40 (firmware 1V) and T41 (firmware 1R) have been confirmed to work
well with the new defaults, so we can stop pestering people to confirm
that fact.

For now, whitelist just these two firmware types.  It is best to have
at least one more firmware type confirmed for Radeon 9xxx and Intel
GMA-2 ThinkPads before removing the confirmation requests entirely.

Use stricter checks to decide that we're running on a supported ThinkPad.
This should remove some possible false positives, although nobody ever

Also, restore bits in the firmware mask after hotkey_source_mask is
changed.  Without this, we leave events disabled...

Subject: thinkpad-acpi: deprecate hotkey_bios_mask

Some analysis of the ACPI DSDTs shows that the HKEY pre-enabled mask
is always 0x80c (FN+F3,FN+F4 and FN+F12), which are the hotkeys that
the second gen of HKEY firmware supported (the first gen didn't report
any hotkeys, the second reported these tree hotkeys but had no mask
support, and the third added mask support).

So, this is probably some sort of backwards compatibility with older
versions of the IBM ThinkVantage suite.  We have no use for that, and
I know of exactly ZERO users of that attribute, anyway.  Start the
process of getting rid of it.

Subject: thinkpad-acpi: Fix procfs hotkey reset command

echo "reset" > /proc/acpi/ibm/hotkey should do something non-useless,
so instead of setting it to Fn+F2, Fn+F3, Fn+F5, set it to
hotkey_recommended_mask.

It is not like it will survive for much longer, anyway.

Subject: thinkpad-acpi: report brightness events when required

Report KEY_BRIGHTNESSUP and KEY_BRIGHTNESSDOWN input events when the
ThinkPad is in "passive brightness control" mode (because either we or
ACPI video touched _BCL), and ACPI video is not processing these
events by itself.

This happens only on Lenovo ThinkPads with ACPI video support, when
operating with the ACPI video driver in acpi_backlight=vendor mode.

Issuing these events is the right thing to do, and will work around
bugzilla #13368, if userspace is properly configured and actively
handles these events.

For other ThinkPads, and when ACPI video is handling brightness
changes, thinkpad-acpi will continue NOT sending KEY_BRIGHTNESS*
events by default.

Subject: topstar-laptop: add new driver for hotkeys support on Topstar N01

This adds Topstar Laptop Extras ACPI driver. It enables hotkeys
functionality with Topstar N01 netbook. Besides hotkeys there are
other functions exposed by its ACPI firmware, but for now only
hotkeys reporting on Topstar N01 is supported. Topstar is a chinese
manufacturer, its website can be currently reached at
http://www.topstardigital.cn/

Subject: hwmon driver for ACPI 4.0 power meters

This driver exposes ACPI 4.0 compliant power meters as hardware monitoring
devices.  This second revision of the driver also exports the ACPI string
info as sysfs attributes, a list of the devices that the meter measures,
and will send ACPI notifications over the ACPI netlink socket.  This
latest revision only enables the power capping controls if it can be
confirmed that the power cap can be enforced by the hardware and explains
how the notification interfaces work.

+Kernel driver power_meter
+=========================
+
+This driver talks to ACPI 4.0 power meters.
+
+Supported systems:
+  * Any recent system with ACPI 4.0.
+    Prefix: 'power_meter'
+    Datasheet: http://acpi.info/, section 10.4.
+
+Author: Darrick J. Wong
+
+Description
+-----------
+
+This driver implements sensor reading support for the power meters exposed in
+the ACPI 4.0 spec (Chapter 10.4).  These devices have a simple set of
+features--a power meter that returns average power use over a configurable
+interval, an optional capping mechanism, and a couple of trip points.  The
+sysfs interface conforms with the specification outlined in the "Power" section
+of Documentation/hwmon/sysfs-interface.
+
+Special Features
+----------------
+
+The power[1-*]_is_battery knob indicates if the power supply is a battery.
+Both power[1-*]_average_{min,max} must be set before the trip points will work.
+When both of them are set, an ACPI event will be broadcast on the ACPI netlink
+socket and a poll notification will be sent to the appropriate
+power[1-*]_average sysfs file.
+
+The power[1-*]_{model_number, serial_number, oem_info} fields display arbitrary
+strings that ACPI provides with the meter.  The measures/ directory contains
+symlinks to the devices that this meter measures.
+
+Some computers have the ability to enforce a power cap in hardware.  If this is
+the case, the power[1-*]_cap and related sysfs files will appear.  When the
+average power consumption exceeds the cap, an ACPI event will be broadcast on
+the netlink event socket and a poll notification will be sent to the
+appropriate power[1-*]_alarm file to indicate that capping has begun, and the
+hardware has taken action to reduce power consumption.  Most likely this will
+result in reduced performance.
+
+There are a few other ACPI notifications that can be sent by the firmware.  In
+all cases the ACPI event will be broadcast on the ACPI netlink event socket as
+well as sent as a poll notification to a sysfs file.  The events are as
+follows:
+
+power[1-*]_cap will be notified if the firmware changes the power cap.
+power[1-*]_interval will be notified if the firmware changes the averaging
+interval.

Subject: acerhdf: fix fan control for AOA150 model

- Apply Borislav Petkov's patch (convert the fancmd[] array to a real
  struct thus disambiguating command handling and making code more
  readable.)

- Add BIOS product to BIOS table as AOA110 and AOA150 have different
  register values

- Add force_product parameter to allow forcing different product

- fix linker warning caused by "acerhdf_drv" not being named
  "acerhdf_driver"

Subject: ACPI: simplify deferred execution path

We had two functions, acpi_os_execute_deferred() and
acpi_os_execute_hp_deferred() that differed only in that the
latter did acpi_os_wait_events_complete(NULL) before executing
the deferred function.

This patch consolidates those two functions and uses a flag in
the struct acpi_os_dpc to determine whether to do the wait.

Subject: ACPI: don't pass handle for fixed hardware notifications

Fixed hardware devices have no handles, so just pass an explicit
NULL rather than something that looks like it might be meaningful.
acpi_device_notify() doesn't need the handle anyway; the only
reason it takes it as an argument is because the acpi_notify_handler
typedef requires it.

From e7d8842ed34a7fe19d1ed90f84c211fb056ac523 Mon Sep 17 00:00:00 2001
From: "Paul E. McKenney" <paulmck@linux.vnet.ibm.com>
Date: Fri, 18 Sep 2009 09:50:18 -0700
Subject: rcu: Apply results of code inspection of kernel/rcutree_plugin.h

o Drop the calls to cpu_quiet() from the online/offline code.
  These are unnecessary, since force_quiescent_state() will
  clean up, and removing them simplifies the code a bit.

o Add a warning to check that we don't enqueue the same blocked
  task twice onto the ->blocked_tasks[] lists.

o Rework the phase computation in rcu_preempt_note_context_switch()
  to be more readable, as suggested by Josh Triplett.

o Disable irqs to close a race between the scheduling clock
  interrupt and rcu_preempt_note_context_switch() WRT the
  ->rcu_read_unlock_special field.

o Add comments to rnp->lock acquisition and release within
  rcu_read_unlock_special() noting that irqs are already
  disabled.

Subject: rcu: Fix thinko, actually initialize full tree

Commit de078d8 ("rcu: Need to update rnp->gpnum if preemptable RCU
is to be reliable") repeatedly and incorrectly initializes the root
rcu_node structure's ->gpnum field rather than initializing the
->gpnum field of each node in the tree.  Fix this.  Also add an
additional consistency check to catch this in the future.

Subject: x86, apic: Use logical flat on intel with <= 8 logical cpus

On Intel platforms, we can use logical flat mode if there are <= 8
logical cpu's (irrespective of physical apic id values). This will
enable simplified and efficient IPI and device interrupt routing on
such platforms.

Fix the relevant comments while we are at it.

We can clean up default_setup_apic_routing() by using apic->probe()
but that is a different item.

Subject: perf: Add a timestamp to fork events

perf timechart needs to know when a process forked, in order to be
able to visualize properly when tasks start.

This patch adds a time field to the event structure, and fills it
in appropriately.

Subject: perf: Store trace event name/id pairs in perf.data

The trace event name<->id mapping is dynamic for each kernel
compile. In order for perf.data to be useable outside the actual
system, we thus need to store a table of this mapping for later
use.

This patch adds this table to perf.data, and provides helper
functions for lookup up fields from this table.

To avoid mistakes, lookup-from-table is kept completely seprate
from lookup-from-local-debugfs.

From 6161352142d5fed4cd753b32e5ccde66e705b14e Mon Sep 17 00:00:00 2001
From: Arjan van de Ven <arjan@linux.intel.com>
Date: Thu, 17 Sep 2009 16:11:28 +0200
Subject: tracing, perf: Convert the power tracer into an event tracer

This patch converts the existing power tracer into an event tracer,
so that power events (C states and frequency changes) can be
tracked via "perf".

This also removes the perl script that was used to demo the tracer;
its functionality is being replaced entirely with timechart.

From f48d55ce7871824eae3065f4d81956d7113eff19 Mon Sep 17 00:00:00 2001

Subject: perf: Add a SVG helper library file

The timechart tool writes out SVG format output; this patch adds a
set of helper functions to abstract dealing with SVG from the core
timechart code.

From 10274989fd595db455874fc2c83272fb33f6b27b Mon Sep 17 00:00:00 2001

Subject: perf: Add the timechart tool

timechart is a tool to visualize what is going on in the system.

The user makes a trace of what is going on with

 > perf record --timechart /usr/bin/some_command

and then can turn the output of this into an svg file

 > perf timechart

which then can be viewed with any SVG view; inkscape works well
enough for me.

The idea behind timechart is to create a "infinitely zoomable"
picture; something that has high level information on a 1:1 zoom
level, but which exposes more details every time you zoom into a
specific area.

Subject: intel-iommu: Limit DOMAIN_MAX_PFN to fit in an 'unsigned long'

This means we're limited to 44-bit addresses on 32-bit kernels, and
makes it sane for us to use 'unsigned long' for PFNs throughout.

Which is just as well, really, since we already do that.

Subject: intel-iommu: Fix integer overflow in
 dma_pte_{clear_range,free_pagetable}()

If end_pfn is equal to (unsigned long)-1, then the loop will never end.

Seen on 32-bit kernel, but could have happened on 64-bit too once we get
hardware that supports 64-bit guest addresses.

Change both functions to a 'do {} while' loop with the test at the end,
and check for the PFN having wrapper round to zero.

Subject: sched: Re-add lost cpu_allowed check to
 sched_fair.c::select_task_rq_fair()

While doing some testing, I pinned mplayer, only to find it
following X around like a puppy. Looking at commit c88d591, I found
a cpu_allowed check that went AWOL.  I plugged it back in where it
looks like it needs to go, and now when I say "sit, stay!", mplayer
obeys again.

'c88d591 sched: Merge select_task_rq_fair() and
sched_balance_self()' accidentally dropped the check, causing
wake_affine() to pull pinned tasks - put it back.

[ v2: use a cheaper version from Peter ]

Subject: fat: Check s_dirt in fat_sync_fs()

If we didn't check sb->s_dirt, it will update the FSINFO
unconditionally. It will reduce the filetime of flash base device.

So, this checks sb->s_dirt. sb->s_dirt is racy, however FSINFO is just
hint. So even if there is race, and we hit it, it would not become big
problem.

And this also is as workaround of suspend problem.

Subject: intel-iommu: Kill DMAR_BROKEN_GFX_WA option.

Just make it depend on BROKEN for now, in case people scream really loud
about it (and because we might want to keep some of this logic for an
upcoming BIOS workaround, so I don't just want to rip it out entirely
just yet). But for graphics devices, it really ought to be unnecessary.

Be more consistent in the svghelper about the minimum text size
by having a global #define for this.

There needs to be a minimum text size in order to keep the size
of the SVG file within the reach of what current SVG viewers can
cope with.

Subject: tracing, x86, cpuidle: Move the end point of a C state in the power
 tracer

The "end of a C state" trace point currently happens before
the code runs that corrects the TSC for having stopped during idle.

The result of this is that the timestamp of the end-of-C-state event
is garbage on cpus where the TSC stops during idle.

This patch moves the end point of the C state to after the timekeeping
engine of the kernel has been corrected.

There is still some weird code in per_copy_attr(). Which supposedly
checks that all bytes trailing a struct are zero.

It doesn't seem to get pointer arithmetic right. Since it
increments an iterating pointer by sizeof(unsigned long) rather
than 1.

Subject: mtd: nand: register orion_nand using platform_driver_probe()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

orion_nand_probe lives in .init.text, so using platform_driver_register to
register it is wrong because binding a device after the init memory is
discarded (e.g.  via sysfs) results in an oops.

As requested by Nicolas Pitre platform_driver_probe is used instead of
moving the probe function to .devinit.text as proposed initially.  This
saves some memory, but devices registered after the driver is probed are
not bound (probably there are none) and binding via sysfs isn't possible.

Subject: mtd: onenand: make onenand/generic.c more generic

Remove the ARM dependency from the generic "onenand" platform device
driver.  This change makes the driver useful for other architectures as
well.  Needed for the SuperH kfr2r09 board.

Apart from the obvious Kconfig bits, the most important change is the move
away from ARM specific includes and platform data.  Together with this
change the only in-tree board code gets an update, and the driver name is
also changed gracefully break potential out of tree drivers.

The driver is also updated to allow NULL as platform data together with a
few changes to make use of resource_size() and dev_name().

Subject: mtd: nand: add "page" parameter to all read_page/read_page_raw APIs

This patch adds a new "page" parameter to all NAND read_page/read_page_raw
APIs.  The read_page API for the new mode ECC_HW_OOB_FIRST requires the
page information to send the READOOB command and read the OOB area before
the data area.

Subject: mtd: nand: add new ECC mode - ECC_HW_OOB_FIRST

This patch adds the new mode NAND_ECC_HW_OOB_FIRST in the nand code to
support 4-bit ECC on TI DaVinci devices with large page (up to 2KiB) NAND
chips.  This ECC mode is similar to NAND_ECC_HW, with the exception of
read_page API that first reads the OOB area, reads the data in chunks,
feeds the ECC from OOB area to the ECC hw engine and perform any
correction on the data as per the ECC status reported by the engine.

"ECC_HW_OOB_FIRST" name suggested by Thomas Gleixner

Subject: mtd: nand: DaVinci: Add 4-bit ECC support for large page NAND chips

This patch adds 4-bit ECC support for large page NAND chips using the new
ECC mode NAND_ECC_HW_OOB_FIRST.  The platform data from board-dm355-evm
has been adjusted to use this mode.

The patches have been verified on DM355 device with 2KiB-page Micron
devices using mtd-tests and JFFS2.  Error correction up to 4 bits has
also been verified using nandwrite/nanddump utilities.

After close looking, commit 8126dec3 will break:

 1. some cpu feature  in early stage too, like cpu_has_x2apic
 2. will break built-in-command line
 3. will break other memmap= and mem=
 4. early_dbgp and early_console that will use early_ioremap to access mmio (?)

So revert it.

Subject: mtd: fix order of TEST/PARTITIONS kconfig options

The MTD_TEST config option was added in between the MTD_PARTITIONS config
and its dependent options which causes the resulting menu system to
display incorrectly as MTD_TEST does not depend on MTD_PARTITIONS.  So
move it up a few lines where it won't cause a problem.

Subject: Driver-Core: extend devnode callbacks to provide permissions

This allows subsytems to provide devtmpfs with non-default permissions
for the device node. Instead of the default mode of 0600, null, zero,
random, urandom, full, tty, ptmx now have a mode of 0666, which allows
non-privileged processes to access standard device nodes in case no
other userspace process applies the expected permissions.

This also fixes a wrong assignment in pktcdvd and a checkpatch.pl complain.

Subject: mtd: m25p80: add support for AAI programming with SST SPI flashes

The SST SPI flashes are a bit non-standard in that they can be programmed
one byte at a time (including address!), or they can be written two bytes
at a time with auto address incrementing (AAI).  The latter form is
obviously much better for performance, so let's use it when possible.

Subject: phram: cleanup error handling and associated messages

The error handling in the phram driver is pretty bad -- in many places,
errors are silently ignored or logged, but then still ignored in the
return value.  So convert all of the code to pass back the correct return
value and log error messages properly (and using the new pr_fmt() helper).

If everything does go smoothly, rather than exit silently, dump a helpful
info message like pretty much every other MTD driver does.

This patch allows i.MX27 to support 2KiB pagesize NAND flash.
We are using a 1.8V NAND flash which datasheet (unfortunately only
available under NDA) says :
Page size: x8: 2,112 bytes (2,048 + 64 bytes).
Without this patch, all sectors are marked as bad eraseblock.

Since early printk only makes sense/works when the serial driver is built
into the kernel, disable the option for this driver when it is going to be
built as a module.  Otherwise we get build failures due to the ifdef
handling.

Subject: tty-ldisc: make /proc/tty/ldiscs use ldisc_ops instead of ldiscs

The /proc/tty/ldiscs file is totally and utterly un-interested in the
"struct tty_ldisc" structures, and only cares about the underlying ldisc
operations.

So don't make it create a dummy 'struct ldisc' only to get a pointer to
the operations, and then destroy it.  Instead, we split up the function
'tty_ldisc_try_get()', and create a 'get_ldops()' helper that just looks
up the ldisc operations based on the ldisc number.

That makes the code simpler to read (smaller and more well-defined
helper functions), and allows the /proc functions to avoid creating that
useless dummy only to immediately free it again.

Subject: tty-ldisc: get rid of tty_ldisc_try_get() helper function

Now that the /proc/tty/ldiscs handling doesn't play games with 'struct
ldisc' any more, the only remaining user of 'tty_ldisc_try_get()' is
'tty_ldisc_get()' (note the lack of 'try').

And we're actually much better off folding the logic directly into that
file, since the 'try' part was always about trying to get the ldisc
operations, not the ldisc itself: and making that explicit inside of
'tty_ldisc_get()' clarifies the whole semantics.

Subject: cyclades: add tty refcounting

While this is not problem for Y card handlers (they are protected
by card_lock), Z handlers and other functions may dereference NULL
at any point after hangup/close. Even if (tty == NULL) was already
performed in the handler.

Note that it's not an issue for Y cards just for now. After
switching to tty_port_close_* et al. this will be a problem. So
add refcounting to them all.

Also proc .show doesn't take a tty reference and it should (along
with a ldisc one).

While at it and changing prototypes (adding tty param), prepend
cy_ to functions which don't have it yet.

Subject: cyclades: remove block_til_ready

Use a tty_port common instead. This saves lots of .text and makes the
code a lot more readable.

This involves separation of a dtr_rts handling, next patches will use
that to not duplicate the code all over the place.

Subject: cyclades: avoid addresses recomputation

Don't fetch firmware address and recompute channel control on each
port access. Precompute the values on init and use them later all
the time.

The same for board control.

This simplify code and improves readability.

Subject: cyclades: switch to tty_port_hangup

Do not duplicate common tty_port_hangup code. Use it instead.

Also do not unset ASYNC_NORMAL_ACTIVE and wake up from the
tty_hangup() caller. It makes no sense since we don't check that
flag in sleepers. tty_port_hangup() performed later will do the
right job.

Subject: cyclades: close cleanup

Use new tty helpers for close, which allows much code removal.

The only real change is locking. card_lock for protecting was
used inappropriately (just to have a critical section, no matter
which lock is used), so the change to port->lock is fine.

Remove also useless debug printks while being there.

Subject: cyclades: overall cleanup

- remove changelog from the file. we don't care about ancient
  history
- update copyright year
- update version
- constify some stuff
- empty lines removal

- * Fix from Corey Minyard, Internet: minyard@metronet.com,
- * UUCP: minyard@wf-rch.cirr.com, WORK: minyardbnr.ca, to
- * cy_hangup that appears to clear up much (all?) of the
- * DTR glitches; also he's added/cleaned-up diagnostic messages
- *
- * Revision 1.29  1994/11/16  04:16:07  bentson
- * add change proposed by Ralph Sims, ralphs@halcyon.com, to
- * operate higher speeds in same way as other serial ports;
- * add more serial ports (for up to two 16-port muxes).
- *
- * Revision 1.28  1994/11/04  00:13:16  root
- * turn off diagnostic messages
- *
- * Revision 1.27  1994/11/03  23:46:37  root
- * bunch of changes to bring driver into greater conformance
- * with the serial.c driver (looking for missed fixes)
- *
- * Revision 1.26  1994/11/03  22:40:36  root
- * automatic interrupt probing fixed.
- *
- * Revision 1.25  1994/11/03  20:17:02  root
- * start to implement auto-irq
- *
- * Revision 1.24  1994/11/03  18:01:55  root
- * still working on modem signals--trying not to drop DTR
- * during the getty/login processes
- *
- * Revision 1.23  1994/11/03  17:51:36  root
- * extend baud rate support; set receive threshold as function
- * of baud rate; fix some problems with RTS/CTS;
- *
- * Revision 1.22  1994/11/02  18:05:35  root
- * changed arguments to udelay to type long to get
- * delays to be of correct duration
- *
- * Revision 1.21  1994/11/02  17:37:30  root
- * employ udelay (after calibrating loops_per_second earlier
- * in init/main.c) instead of using home-grown delay routines
- *
- * Revision 1.20  1994/11/02  03:11:38  root
- * cy_chars_in_buffer forces a return value of 0 to let
- * login work (don't know why it does); some functions
- * that were returning EFAULT, now executes the code;
- * more work on deciding when to disable xmit interrupts;
- *
- * Revision 1.19  1994/11/01  20:10:14  root
- * define routine to start transmission interrupts (by enabling
- * transmit interrupts); directly enable/disable modem interrupts;
- *
- * Revision 1.18  1994/11/01  18:40:45  bentson
- * Don't always enable transmit interrupts in startup; interrupt on
- * TxMpty instead of TxRdy to help characters get out before shutdown;
- * restructure xmit interrupt to check for chars first and quit if
- * none are ready to go; modem status (MXVRx) is upright, _not_ inverted
- * (to my view);
- *
- * Revision 1.17  1994/10/30  04:39:45  bentson
- * rename serial_driver and callout_driver to cy_serial_driver and
- * cy_callout_driver to avoid linkage interference; initialize
- * info->type to PORT_CIRRUS; ruggedize paranoia test; elide ->port
- * from cyclades_port structure; add paranoia check to cy_close;
- *
- * Revision 1.16  1994/10/30  01:14:33  bentson
- * change major numbers; add some _early_ return statements;
- *
- * Revision 1.15  1994/10/29  06:43:15  bentson
- * final tidying up for clean compile;  enable some error reporting
- *
- * Revision 1.14  1994/10/28  20:30:22  Bentson
- * lots of changes to drag the driver towards the new tty_io
- * structures and operation.  not expected to work, but may
- * compile cleanly.
- *
- * Revision 1.13  1994/07/21  23:08:57  Bentson
- * add some diagnostic cruft; support 24 lines (for testing
- * both -8Y and -16Y cards; be more thorough in servicing all
- * chips during interrupt; add "volatile" a few places to
- * circumvent compiler optimizations; fix base & offset
- * computations in block_til_ready (was causing chip 0 to
- * stop operation)
- *
- * Revision 1.12  1994/07/19  16:42:11  Bentson
- * add some hackery for kernel version 1.1.8; expand
- * error messages; refine timing for delay loops and
- * declare loop params volatile
- *
- * Revision 1.11  1994/06/11  21:53:10  bentson
- * get use of save_car right in transmit interrupt service
- *
- * Revision 1.10.1.1  1994/06/11  21:31:18  bentson
- * add some diagnostic printing; try to fix save_car stuff
- *
- * Revision 1.10  1994/06/11  20:36:08  bentson
- * clean up compiler warnings
- *
- * Revision 1.9  1994/06/11  19:42:46  bentson
- * added a bunch of code to support modem signalling
- *
- * Revision 1.8  1994/06/11  17:57:07  bentson
- * recognize break & parity error
- *
- * Revision 1.7  1994/06/05  05:51:34  bentson
- * Reorder baud table to be monotonic; add cli to CP; discard
- * incoming characters and status if the line isn't open; start to
- * fold code into cy_throttle; start to port get_serial_info,
- * set_serial_info, get_modem_info, set_modem_info, and send_break
- * from serial.c; expand cy_ioctl; relocate and expand config_setup;
- * get flow control characters from tty struct; invalidate ports w/o
- * hardware;
- *
- * Revision 1.6  1994/05/31  18:42:21  bentson
- * add a loop-breaker in the interrupt service routine;
- * note when port is initialized so that it can be shut
- * down under the right conditions; receive works without
- * any obvious errors
- *
- * Revision 1.5  1994/05/30  00:55:02  bentson
- * transmit works without obvious errors
- *
- * Revision 1.4  1994/05/27  18:46:27  bentson

- *
- * Revision 1.3  1994/05/25  22:12:44  bentson
- * shifting from multi-port on a card to proper multiplexor
- * data structures;  added skeletons of most routines
- *
- * Revision 1.2  1994/05/19  13:21:43  bentson
- * start to crib from other sources
- *

Subject: cyclades: use dtr_rts helpers

For Z cards, use tty helpers for dtr_rts.

If we did the same for Y cards, it will cause a deadlock, because
cyy_dtr_rts takes a lock which we already hold.

Instead, we introduce a Y helper expecting card lock to be held.
It may then be called with set/clear masks from other places.

Subject: cyclades: ioctls cleanup

- add a cy_ prefix to functions with changed prototypes
- cy_get_serial_info: initialize serial_struct by initializer,
  save a memset
- inline simple functions (get_mon_info, {s,g}et_default_threshold,
  {s,g}et_default_timeout) directly in the ioctl handler
- add a cy_cflags_changed helper to not copy its code by
  wait_event_interruptible
- remove some ret_val = 0 assignments, it's preset to 0
- TIOCGICOUNT: don't do many put_user's, do one copy_to_user

Subject: cyclades: tiocm cleanup

- save one indent level by inverting !fw_loaded condition
- read rs_status on Z and write it after we change all the flags,
  don't do that separately
- remove Y inverted rts/dtr branching, precompute registers and use
  them

Subject: cyclades: introduce cyy_readb/writeb

Add helpers for io operations, so that we can eliminate huge
amount of supporting code. It is now centralized in those
helpers and used values are precomputed in the init phase.

Subject: cyclades: remove more duplicated code

Remove duplicated code from cy_set_line_char. There were 2 if
branches with same contents except flags.

Branch only for the flags computation and use them in the only copy
of the code.

Subject: slip: Clean up create and destroy

The network layer now has a destructor we can hook to clean up the slip
devices array. That needs us to initiate unregister events in the right
places which with the current tty layer we can do, and with network
refcounting is safe to do.

Currently kfifo cannot be used by parts of the kernel that use "const"
properly as kfifo itself does not use const for passed data blocks which
are indeed const.

Subject: serial: 8250: add IRQ trigger support

There is currently no provision for passing IRQ trigger flags for
serial IRQs with triggering requirements (such as GPIO IRQs)

This patch adds irqflags to plat_serial8250_port that can be passed
from board file to reqest_irq() of 8250 driver

Changes are backward compatible with boards passing UPF_SHARE_IRQ flag

Tested on Zoom2 board that has IRQF_TRIGGER_RISING requirement for 8250 irq

[Moved new flag to end to fix bugs in the original with the old_serial array

Subject: 8250: Now honours baud rate lower bounds

A platform clock drives 8250 ports in most SOC systems, the clock
might run at high frequencies, and so it's not always possible to
downscale uart clock to a desired value.

Currently the 8250 uart driver accepts not supported baud rates, and
what is worse, it is doing this silently, and then passes not accepted
values to a new termios, so userspace has no chance to catch this kind
of errors (userspace verifies that settings were accepted by reading
back and comparing the settings).

This patch fixes the issue by passing minimum baud rate to the
uart_get_baud_rate() call, the call should take care of all bounds,
so userspace should now report:

  # stty -F /dev/ttyS0 speed 300
  115200
  stty: /dev/ttyS0: unable to perform all requested operations

p.s. uart_get_baud_rate() falls back to 9600, which still might be too
     low for some 10 GHz platforms, but that's a separate issue, and
     we can wait with fixing this till we find such a platform.

Subject: tty: Add a full port_close function

Now we are extracting out methods for shutdown and the like we can add a
proper tty_port_close method that knows all the innards of the tty closing
process and hides the lot from the caller.

At some point in the future this will be paired with a similar open()
helper and the drivers can stick to hardware management.

Subject: tty: USB hangup is racy

The USB layer uses tty_hangup to deal with unplugs of the physical hardware
(analogous to loss of carrier) and then frees the resources. However the
tty_hangup is asynchronous. As the hangup can sleep we can use tty_vhangup
which is the non async version to avoid freeing resources too early.

Subject: vt: add an event interface

This is needed and requested in various forms for ConsoleKit, screenblank
handling and the like so do the job with a single interface. Also build the
interface so that unlike VT_WAITACTIVE and friends it won't miss events.

FIXME: Should this be a waitactive ioctl or a new device file you can poll
and read events from. We need the code anyway to fix up the existing broken
wait for console switch logic but the ConsoleKit people would prefer the
new device to the ioctl we have here

code and dumped them in kernel/power. They have all sorts of deep relations
with the vt code so put them in the vt tree instead

Subject: serial: use tty_port pointers in the core code

Extract out a lot of the x.port. uses and also show up where there are
things left to be isolated that prevent use using the port helpers in the
serial layer at this point

Subject: serial: move the flags into the tty_port field

Fortunately the serial layer was designed to use the same flag values but
with different names. It has its own SUSPENDED flag which is a free slot in
the ASYNC flags so we allocate it in the ASYNC flags instead.

The serial layer for some reason uses different defines for the special
case close delays and then conditionally switches to/from the normal ones
in the ioctls.

Remove this rather pointless abstraction

Subject: Set proper console speed on resume if console suspend is disabled

Commit b5b82df6, from May 2007, breaks no_console_suspend on the OLPC
XO laptop. Basically what happens is that upon returning from resume,
serial8250_resume_port() will reconfigure the port for high speed
mode and all console output will be garbled, making debug of the
resume path painful. This patch modifies uart_resume_port() to
reset the port to the state it was in before we suspended.

Original patch by Marcelo Tosatti

Second patch by Deepak then reworked by Alan to fit with the tty changes
before it got submitted. Also fixed the console path to set c_i/ospeed as
some drivers require the termios fields are valid

Various drivers have hacks to mangle termios structures. This stems from
the fact there is no nice setup hook for configuring the termios settings
when the port is created

Subject: n_tty: honor opost flag for echoes

Fixes the following bug:

      http://bugs.linuxbase.org/show_bug.cgi?id=2692

Causes processing of echoed characters (output from the echo buffer) to
honor the O_OPOST flag, which is consistent with the old behavior.

Note that this and the next patch ("n_tty: move echoctl check and
clean up logic") were verified together by the bug reporters, and
the test now passes.

Subject: n_tty: move echoctl check and clean up logic

Check L_ECHOCTL before insertting a character in the echo buffer
(rather than as the buffer is processed), to be more consistent with
when all other L_ flags are checked.  Also cleaned up the related logic.

Note that this and the previous patch ("n_tty: honor opost flag for echoes")
were verified together by the reporters of the bug that patch addresses
(http://bugs.linuxbase.org/show_bug.cgi?id=2692), and the test now passes.

Subject: tty: handle VT specific compat ioctls in vt driver

The VT specific compat_ioctl handlers are the only ones
in common code that require the BKL. Moving them into
the vt driver lets us remove the BKL from the other handlers
and cleans up the code.

Subject: tty: Power: fix suspend vt regression

vt_waitactive no longer accepts console parameter as console-1
since commit "vt: add an event interface". It expects console
number directly (as viewed by userspace -- counting from 1).

Fix a deadlock suspend regression by redefining adding one
to vt in vt_move_to_console.

Subject: tty: riscom8, fix tty refcnt

Stanse found a tty refcnt leak on one fail path in rc_transmit.
Fix that by jumping to the 'out' label.

Subject: tty: USB: serial/mct_u232, fix tty refcnt

Stanse found a tty refcnt leak in read_int_callback. In fact
it's handled wrong altogether. tty_port_tty_get can return NULL
and it's not checked in that manner.

Fix that by checking the tty_port_tty_get retval and put tty kref
properly.

Add support for MOXA:0x1120 pci device. It's a 2-port device and differs
in no way from the others. So this turns out to be a trivial
pci_device_id change.

Increase also the version number.

So switch UART_LSR_TEMT to UART_LSR_THRE in that specific case
according to the change in 1.14 moxa drivers.

Subject: usb-serial: change referencing of port and serial structures

This patch (as1284) changes the referencing of the usb_serial and
usb_serial_port structures in usb-serial.c.  It's not feasible to make
the port structures keep a reference to the serial structure, because
the ports need to remain in existence when serial is released -- quite
a few of the drivers expect this.  Consequently taking a reference
to the port when the device file is open is insufficient; such a
reference would not pin serial.

To fix this, we now take a reference to serial when the device file is
opened.  The final put_device() for the ports occurs in
destroy_serial(), so that the ports will last as long as they are
needed.

The patch initializes all the port devices, including those in the
unused "fake" ports.  This makes the code more uniform because they
can all be released in the same way.  The error handling code in
usb_serial_probe() is much simplified by this approach; instead of
freeing everything by hand we can use a single usb_serial_put() call.

Also simplified is the port-release mechanism.  Instead of being two
separate routines, port_release() and port_free() can be combined into
one.

Subject: usb-serial: change logic of serial lookups

This patch (as1286) changes usb_serial_get_by_index().  Now the
routine will check whether the serial device has been disconnected; if
it has then the return value will be NULL.  If the device hasn't been
disconnected then the routine will return with serial->disc_mutex
held, so that the caller can use the structure without fear of racing
against driver unloads.

This permits the scope of table_mutex in destroy_serial() to be
reduced.  Instead of protecting the entire function, it suffices to
protect the part that actually uses serial_table[], i.e., the call to
return_serial().  There's no longer any danger of the refcount being
incremented after it reaches 0 (which was the reason for having the
large scope previously), because it can't reach 0 until the serial
device has been disconnected.

Also, the patch makes serial_install() check that serial is non-NULL
before attempting to use it.

Subject: usb-serial: acquire references when a new tty is installed

This patch (as1287) makes serial_install() be reponsible for acquiring
references to the usb_serial structure and the driver module when a
tty is first used.  This is more sensible than having serial_open() do
it, because a tty can be opened many times whereas it is installed
only once, when it is created.  (Not to mention that these actions are
reversed when the tty is released, not when it is closed.)  Finally,
it is at install time that the TTY core takes its own reference to the
usb_serial module, so it is only fitting that we should act the same
way in regard to the lower-level serial driver.

Subject: usb-serial: fix termios initialization logic

This patch (as1288) fixes the initialization logic in
serial_install().  A new tty always needs to have a termios
initialized no matter what, not just in the case where the lower
driver will override the termios settings.

Subject: usb-serial: add missing tests and debug lines

This patch (as1290) adds some missing tests.  serial_down() isn't
supposed to do anything if the hardware hasn't been initialized, and
serial_close() isn't supposed to do anything if the tty has gotten a
hangup (because serial_hangup() takes care of shutting down the
hardware).

The patch also updates and adds a few debugging lines.

Subject: usb-serial: straighten out serial_open

This patch (as1291) removes a bunch of code from serial_open(), things
that were rendered unnecessary by earlier patches.  A missing spinlock
is added to protect port->port.count, which needs to be incremented
even if the open fails but not if the tty has gotten a hangup.  The
test for whether the hardware has been initialized, based on the use
count, is replaced by a more transparent test of the
ASYNCB_INITIALIZED bit in the port flags.

Subject: USB serial: update the console driver

This patch (as1292) modifies the USB serial console driver, to make it
compatible with the recent changes to the USB serial core.  The most
important change is that serial->disc_mutex now has to be unlocked
following a successful call to usb_serial_get_by_index().

Other less notable changes include:

	Use the requested port number instead of port 0 always.

	Prevent the serial device from being autosuspended.

	Use the ASYNCB_INITIALIZED flag bit to indicate when the
	port hardware has been initialized.

In spite of these changes, there's no question that the USB serial
console code is still a big hack.

Subject: mtd: maps: add mtd-ram support to physmap_of
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Use physmap_of to access RAMs as mtd and add documenation for it. This approach
is a lot less intrusive as adding an of-wrapper around plat-ram.c. As most
extensions of plat-ram.c (e.g. custom map-functions) can't be mapped to the
device tree anyhow, extending physmap_of seems to be the cleanest approach.

Tested with a phyCORE-MPC5121e.

Subject: mtd: omap: add support for nand prefetch-read and post-write

This patch adds prefetch support to access nand flash in mpu mode.
This patch also adds 8-bit nand support (omap_read/write_buf8).
Prefetch can be used for both 8- and 16-bit devices.

Subject: driver/Makefile: Initialize "mtd" and "spi" before "net"

On TI's da850/omap-l138 EVM, MAC address is stored in SPI flash.

This patch changes the initialization sequence of the drivers
by moving mtd and spi ahead of net in drivers/Makefile thereby
enabling da850/omap-l138 ethernet driver to read the MAC address
while booting.

The previous implementation breaks the dts binding "mtd-physmap.txt". This
implementation fixes the issue by checking the availability of the reg

Subject: mtd: nand: fix ECC Correction bug for SMC ordering for NDFC driver

Fix ECC Correction bug where the byte offset location were double
fliped causing correction routine to toggle the wrong byte location
in the ECC segment. The ndfc_calculate_ecc routine change the order
of getting the ECC code.
        /* The NDFC uses Smart Media (SMC) bytes order */
        ecc_code[0] = p[2];
        ecc_code[1] = p[1];
        ecc_code[2] = p[3];
But in the Correction algorithm when calculating the byte offset
location, the b1 is used as the upper part of the address. Which
again reverse the order making the final byte offset address
location incorrect.
	byte_addr = (addressbits[b1] << 4) + addressbits[b0];
The order is change to read it in straight and let the correction
function to revert it to SMC order.

Subject: mtd: cfi_cmdset_0002: add 0xFF intolerance for M29W128G

The M29W128G Numonyx flash devices are intolerant to any 0xFF command:
in the Cfi_util.c the function cfi_qry_mode_off() (that resets the device
after the autoselect mode) must have a 0xF0 command after the 0xFF command.
This fix solves also the cause of the fixup_M29W128G_write_buffer() fix,
that can be removed now.
The following patch applies to 2.6.30 kernel.

Subject: mtd: nand: add __nand_correct_data helper function

Split nand_correct_data() into two part, a pure calculation function
and a wrapper for mtd interface.

The tmio_nand driver can implement its ecc.correct function easily
using this __nand_correct_data helper.

Subject: mtd: nand: fix tmio_nand ecc correction

This driver may be reading 512 bytes at a times, but still calculates
256-byte sector ECC.  So the nand_correct_data() is not appropriate
for this driver.  Implement its ecc.correct function calling
__nand_correct_data() twice.

Subject: kbuild: use INSTALLKERNEL to select customized installkernel script

Replace the use of CROSS_COMPILE to select a customized
installkernel script with the possibility to set INSTALLKERNEL
to select a custom installkernel script when running make:

    make INSTALLKERNEL=arm-installkernel install

With this patch we are now more consistent across
different architectures - they did not all support use
of CROSS_COMPILE.

The use of CROSS_COMPILE was a hack as this really belongs
to gcc/binutils and the installkernel script does not change
just because we change toolchain.

The use of CROSS_COMPILE caused troubles with an upcoming patch
that saves CROSS_COMPILE when a kernel is built - it would no
longer be installable.
[Thanks to Peter Z. for this hint]

This patch undos what Ian did in commit:

  0f8e2d62fa04441cd12c08ce521e84e5bd3f8a46
  ("use ${CROSS_COMPILE}installkernel in arch/*/boot/install.sh")

The patch has been lightly tested on x86 only - but all changes
looks obvious.

Subject: kbuild: save ARCH & CROSS_COMPILE when building a kernel

When building a kernel for a different architecture
kbuild requires the user always to specify ARCH and
CROSS_COMPILE on the command-line.

We use the asm symlink to detect if user forgets to
specify the correct ARCH value - but that symlink
is about to die. And we do now want to loose this check.

This patch save the settings of ARCH and CROSS_COMPILE
in two files named:

    include/generated/kernel.arch
    include/generated/kernel.cross

The settings are saved during "make *config" time
and always read.

If user try to change the settings we error out.

This works both for plain builds and for O=...
builds.

So now you can do:
$ mkdir sparc64
$ make O=sparc64 ARCH=sparc64 CROSS_COMPILE=sparc64-linux- defconfig
$ cd sparc64
$ make

Notice that you no longer need to tell kbuild
the settings of ARCH and CROSS_COMPILE when you type make
in the output directory.

Likewise for plain builds where you do not use O=...

Subject: kconfig: add symbol value to help find the real depend

Sometimes when configuring need to disable some unused item, but the item is
selected by many other items, it's hard to find the real dependency which
selected it, This patch add every symbol's value accompanied to make it
possible to find the real dependency easily.

An example is CONFIG_RFKILL,

Subject: kbuild: rename ld-option to cc-ldoption

ld-option is misnamed as it test options to gcc, not to ld.
Renamed it to reflect this.

The new alternative `gold' linker in recent binutils doesn't support

Subject: ctags: usability fix

The tag file generated by the tags.sh script has some issue.

First:
  The identifier-list miss the
  DEFINE_TRACE,EXPORT_TRACEPOINT_SYMBOL,EXPORT_TRACEPOINT_SYMBOL_GPL
  special handling, which can result in a wrong tag, not to jump to the
  right variable definition or function implementation.

Second:
  It makes no real sense to include function prototypes and external and
  forward variable declarations, because jumping to a tag will sometimes
  go to this and not to the real definition and implementation. The information
  about the declaration is still there at the definition and implementation
  place.

So this patch make it lot easier to navigate through the kernel source
tree using vi.

Subject: markup_oops: use modinfo to avoid confusion with underscored module
 names
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When EIP is at a module having an underscore in its name, the current code
fails to find it because the module filenames has '-' instead of '_'.  Use
modinfo for a better path finding.

checkincludes.pl is more useful if it actually removed the lines.  This

Subject: kbuild: fix cc1 options check to ensure we do not use -fPIC when
 compiling

The arch/*/boot/Makefile use cc-options to check for GCC command options
and cc-options use the hardened specs when checking for GCC command
options.  When -fPIE is pass to cc1 it can't use -ffreestanding or
-fno-toplevel-reorder.  Then it fail to build stuff with -ffreestanding
and -fno-toplevel-reorder.

Thanks to Fredric Johansson for finding the main problem behind a failed
build using a hardened toolchain.

Subject: gconfig: disable "typeahead find" search in treeviews
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When typeahead find is enabled, using 'y', 'n' and 'm' to change the status
of the configuration items will also start up the search system, making you
jump around the configuration.

Disabling the enable_search property does not mean that search is not
possible, it only disables the typeahead; to execute a search in the
treeview, you can just call it up explicitly (i.e.: on most systems that
will be Ctrl-f).

From 51b563fc93c8cb5bff1d67a0a71c374e4a4ea049 Mon Sep 17 00:00:00 2001
From: Sam Ravnborg <sam@ravnborg.org>
Date: Sun, 20 Sep 2009 12:28:22 +0200
Subject: arm, cris, mips, sparc, powerpc, um, xtensa: fix build with bash 4.0

Albin Tonnerre <albin.tonnerre@free-electrons.com> reported:

    Bash 4 filters out variables which contain a dot in them.
    This happends to be the case of CPPFLAGS_vmlinux.lds.
    This is rather unfortunate, as it now causes
    build failures when using SHELL=/bin/bash to compile,
    or when bash happens to be used by make (eg when it's /bin/sh)

Remove the common definition of CPPFLAGS_vmlinux.lds by
pushing relevant stuff to either Makefile.build or the
arch specific kernel/Makefile where we build the linker script.

This is also nice cleanup as we move the information out where
it is used.

Notes for the different architectures touched:

arm - we use an already exported symbol
cris - we use a config symbol aleady available
       [Not build tested]
mips - the jiffies complexity has moved to vmlinux.lds.S where we need it.
       Added a few variables to CPPFLAGS - they are only used by
       the linker script.
       [Not build tested]
powerpc - removed assignment that is not needed
          [not build tested]
sparc - simplified it using $(BITS)
um - introduced a few new exported variables to deal with this
xtensa - added options to CPP invocation
         [not build tested]

Subject: ARM: Separate out access error checking

Since we get notified separately about prefetch aborts, which may be
permission faults, we need to check for appropriate access permissions
when handling a fault.  This patch prepares us for doing this by
separating out the access error checking.

Subject: ARM: Add support for checking access permissions on prefetch aborts

ARMv6 introduces non-executable mappings, which can cause prefetch aborts
when an attempt is made to execute from such a mapping.  Currently, this
causes us to loop in the page fault handler since we don't correctly
check for proper permissions.

Fix this by checking that VMAs have VM_EXEC set for prefetch aborts.

Subject: perf timechart: Show the duration of scheduler delays in the SVG

Given that scheduler latencies are the hot thing nowadays, show the
duration of said latencies in the SVG in text form.

In addition, if the latency is more than 10 msec, pick a brighter
yellow color as a way to point these long delays out.

Subject: perf util: Make the timechart SVG width dynamic

This patch adds a command line option for timechart that allows the
user to specify the width of the SVG file.

This patch also makes sure that each second of recording has at
least 200 units (pixels at 96 DPI) of width.  This impacts
recordings longer than 5 seconds; recordings shorter than 5 second
will scale up to have a width of 1000 units for the whole recording
(as before).

Subject: perf util: SVG performance improvements

Tweak the output SVG to increase performance in SVG viewers by
limiting the different types of font sizes and by smarter
transformations on the text.

At least with Inkscape this gives a notable performance improvement
during zoom and scrolling.

Subject: thinkpad-acpi: don't leave ERR_PTR() pointers around

backlight_device_register returns ERR_PTR() in case of problems, and
the current code would leave that ERR_PTR in ibm_backlight_device.

The current code paths won't touch it in that situation, but that could
change.  Make sure to set ibm_backlight_device to NULL in the error
path.

Subject: thinkpad-acpi: remove uneeded tp_features.hotkey tests in hotkey_exit

hotkey_exit() is only called if hotkey_init() finished sucessfully, or
by direct calls inside hotkey_init().  The tp_features.hotkey test is
always true, and just adds to the confusion, remove it.  Also, avoid
calling hotkey_mask_set() when it won't do anything useful.

Subject: thinkpad-acpi: drop HKEY event 0x5010

HKEY event 0x5010 is useless to us: old ThinkPads don't issue it.  Newer
ThinkPads won't issue it anymore.  And all ThinkPads issue 0x1010 and
0x1011 events.

Just silently drop it instead of sending it to userspace.

Subject: thinkpad-acpi: hotkey event driver update

Update the HKEY event driver to:

1. Handle better the second-gen firmware, which has no HKEY mask
   support but does report FN+F3, FN+F4 and FN+F12 without the need
   for NVRAM polling.

   a) always make the mask-related attributes available in sysfs;
   b) use DMI quirks to detect the second-gen firmware;
   c) properly report that FN+F3, FN+F4 and FN+F12 are enabled,
      and available even on mask-less second-gen firmware;

2. Decouple the issuing of hotkey events towards userspace from
   their reception from the firmware.  ALSA mixer and brightness
   event reporting support will need this feature.

3. Clean up the mess in the hotkey driver a great deal.  It is
   still very convoluted, and wants a full refactoring into a
   proper event API interface, but that is not going to happen
   today.

4. Fully reset firmware interface on resume (restore hotkey
   mask and status).

5. Stop losing polled events for no good reason when changing the
   mask and poll frequencies.  We will still lose them when the
   hotkey_source_mask is changed, as well as any that happened
   between driver suspend and driver resume.

The hotkey subdriver now has the notion of user-space-visible hotkey
event mask, as well as of the set of "hotkey" events the driver needs
(because brightness/volume change reports are not just keypress
reports in most ThinkPad models).

With this rewrite, the ABI level is bumped to 0x020500 should
userspace need to know it is dealing with the updated hotkey
subdriver.

Subject: thinkpad-acpi: add internal hotkey event API

Add an internal API to the driver, to allow subdrivers to request and
receive HKEY 0x1000 events.  This API will be used by the backlight
(brightness up/down) and upcoming ALSA mixer (volume up/down/mute)
subdrivers.

Subject: sched: Fix raciness in runqueue_is_locked()

runqueue_is_locked() is unavoidably racy due to a poor interface design.
It does

	cpu = get_cpu()
	ret = some_perpcu_thing(cpu);
	put_cpu(cpu);
	return ret;

Its return value is unreliable.

Fix.

Subject: x86, apic: Fix missed handling of discrete apics

In case of discrete (pretty old) apics we may have cpu_has_apic bit
not set but have to check if smp_found_config (MP spec) is there
and apic was not disabled.

Also don't forget to print apic/io-apic for such case as well.

While these don't get actively used (afaict), it still doesn't hurt
for them to properly reflect what how respective segments will get
mapped/ accessed.

Subject: x86: Print the hypervisor returned tsc_khz during boot

On an AMD-64 system the processor frequency that is printed during
system boot, may be different than the tsc frequency that was
returned by the hypervisor, due to the value returned from
calibrate_cpu.

For debugging timekeeping or other related issues it might be
better to get the tsc_khz value returned by the hypervisor.

The patch below now prints the tsc frequency that the VMware
hypervisor returned.

Subject: loongson: fix cut-and-paste mis-merge

Ingo points out that I screwed up when merging the 'timers-for-linus'
branch in commit a03fdb7612874834d6847107198712d18b5242c7.

A bit too much copy-and-pasting caused the end result to have an
extraneous 'return' in the middle of an expression.  That was obviously
bogus.  Blush.

Subject: kbuild: Don't define ALIGN and ENTRY when preprocessing linker
 scripts.

Adding a reference to <linux/linkage.h> to x86's <asm/cache.h> causes
the x86 linker script to have syntax errors, because the ALIGN and
ENTRY keywords get redefined to the assembly implementations of those.
One could fix this by adjusting the include structure, but I think any
solution based on that approach would be fragile.

Currently, it is impossible when writing a header to do something
different for assembly files and linker scripts, even though there are
clearly cases where one wants them to define macros differently for
the two (ENTRY being an excellent example).
So I think the right solution here is to introduce a new preprocessor
definition, called LINKER_SCRIPT that is set along with __ASSEMBLY__
for linker scripts, and to use that to not define ALIGN and ENTRY in
linker scripts.
I suspect we'll find other uses for this mechanism in
the future.

Subject: drm/radeon: some r420s have a CP race with the DMA engine.

This patch makes sure the CP doesn't DMA do VRAM while 2D
is active by inserting a CP resync token.

todo: port to kms.

Subject: drm/vgaarb: add VGA arbitration support to the drm and kms.

VGA arb requires DRM support for non-kms drivers, to turn on/off
irqs when disabling the mem/io regions.

VGA arb requires KMS support for GPUs where we can turn off VGA
decoding. Currently we know how to do this for intel and radeon
kms drivers, which allows them to be removed from the arbiter.

This patch comes from Fedora rawhide kernel.

Subject: perf_counter, powerpc, sparc: Fix compilation after
 perf_counter_overflow() change

Commit 5622f295 ("x86, perf_counter, bts: Optimize BTS overflow
handling") removed the regs field from struct perf_sample_data and
added a regs parameter to perf_counter_overflow().  This breaks the
build on powerpc (and Sparc) as reported by Sachin Sant:

  arch/powerpc/kernel/perf_counter.c: In function 'record_and_restart':
  arch/powerpc/kernel/perf_counter.c:1165: error: unknown field 'regs' specified in initializer

This adjusts arch/powerpc/kernel/perf_counter.c to correspond with the
new struct perf_sample_data and perf_counter_overflow().

[ v2: also fix Sparc, Markus Metzger <markus.t.metzger@intel.com> ]

Subject: perf_counter: Rename list_entry -> group_entry, counter_list ->
 group_list

This is in preparation of the big rename, but also makes sense
in a standalone way: 'list_entry' is a bad name as we already
have a list_entry() in list.h.

Also, the 'counter list' is too vague, it doesnt tell us the
purpose of that list.

Clarify these names to show that it's all about the group
hiearchy.

Subject: perf: Do the big rename: Performance Counters -> Performance Events

Bye-bye Performance Counters, welcome Performance Events!

In the past few months the perfcounters subsystem has grown out its
initial role of counting hardware events, and has become (and is
becoming) a much broader generic event enumeration, reporting, logging,
monitoring, analysis facility.

Naming its core object 'perf_counter' and naming the subsystem
'perfcounters' has become more and more of a misnomer. With pending
code like hw-breakpoints support the 'counter' name is less and
less appropriate.

All in one, we've decided to rename the subsystem to 'performance
events' and to propagate this rename through all fields, variables
and API names. (in an ABI compatible fashion)

The word 'event' is also a bit shorter than 'counter' - which makes
it slightly more convenient to write/handle as well.

Thanks goes to Stephane Eranian who first observed this misnomer and
suggested a rename.

User-space tooling and ABI compatibility is not affected - this patch
should be function-invariant. (Also, defconfigs were not touched to
keep the size down.)

This patch has been generated via the following script:

  FILES=$(find * -type f | grep -vE 'oprofile|[^K]config')

  sed -i \
    -e 's/PERF_EVENT_/PERF_RECORD_/g' \
    -e 's/PERF_COUNTER/PERF_EVENT/g' \
    -e 's/perf_counter/perf_event/g' \
    -e 's/nb_counters/nb_events/g' \
    -e 's/swcounter/swevent/g' \
    -e 's/tpcounter_event/tp_event/g' \
    $FILES

  for N in $(find . -name perf_counter.[ch]); do
    M=$(echo $N | sed 's/perf_counter/perf_event/g')
    mv $N $M
  done

  FILES=$(find . -name perf_event.*)

  sed -i \
    -e 's/COUNTER_MASK/REG_MASK/g' \
    -e 's/COUNTER/EVENT/g' \
    -e 's/\<event\>/event_id/g' \
    -e 's/counter/event/g' \
    -e 's/Counter/Event/g' \
    $FILES

... to keep it as correct as possible. This script can also be
used by anyone who has pending perfcounters patches - it converts
a Linux kernel tree over to the new naming. We tried to time this
change to the point in time where the amount of pending patches
is the smallest: the end of the merge window.

Namespace clashes were fixed up in a preparatory patch - and some
stylistic fallout will be fixed up in a subsequent patch.

( NOTE: 'counters' are still the proper terminology when we deal
  with hardware registers - and these sed scripts are a bit
  over-eager in renaming them. I've undone some of that, but
  in case there's something left where 'counter' would be
  better than 'event' we can undo that on an individual basis
  instead of touching an otherwise nicely automated patch. )

- * in all of a set of classes.  (For example, on PPC970, you can't select
- * events from the FPU, ISU and IDU simultaneously, although any two are
- * possible.)  For N classes, the field is N+1 bits wide, and each class
- * is assigned one bit from the least-significant N bits.  The mask has
- * only the most-significant bit set, and the value has only the bit
- * for the event's class set.  The test_adder has the least significant
- * bit set in the field.
- *
- * If an event is not subject to the constraint expressed by a particular
- * field, then it will have 0 in both the mask and value for that field.

+ * events from the FPU, ISU and IDU simultaneously, although any two are
+ * possible.)  For N classes, the field is N+1 bits wide, and each class
+ * is assigned one bit from the least-significant N bits.  The mask has
+ * only the most-significant bit set, and the value has only the bit
+ * for the event_id's class set.  The test_adder has the least significant
+ * bit set in the field.
+ *
+ * If an event_id is not subject to the constraint expressed by a particular
+ * field, then it will have 0 in both the mask and value for that field.

-/* Sparc64 chips have two performance counters, 32-bits each, with
- * overflow interrupts generated on transition from 0xffffffff to 0.
- * The counters are accessed in one go using a 64-bit register.
- *
- * Both counters are controlled using a single control register.  The
- * only way to stop all sampling is to clear all of the context (user,
- * supervisor, hypervisor) sampling enable bits.  But these bits apply
- * to both counters, thus the two counters can't be enabled/disabled
- * individually.
- *
- * The control register has two event fields, one for each of the two
- * counters.  It's thus nearly impossible to have one counter going
- * while keeping the other one stopped.  Therefore it is possible to
- * get overflow interrupts for counters not currently "in use" and
- * that condition must be checked in the overflow interrupt handler.
- *
- * So we use a hack, in that we program inactive counters with the
- * "sw_count0" and "sw_count1" events.  These count how many times
- * the instruction "sethi %hi(0xfc000), %g0" is executed.  It's an
- * unusual way to encode a NOP and therefore will not trigger in
- * normal code.

+/* Sparc64 chips have two performance counters, 32-bits each, with
+ * overflow interrupts generated on transition from 0xffffffff to 0.
+ * The counters are accessed in one go using a 64-bit register.
+ *
+ * Both counters are controlled using a single control register.  The
+ * only way to stop all sampling is to clear all of the context (user,
+ * supervisor, hypervisor) sampling enable bits.  But these bits apply
+ * to both counters, thus the two counters can't be enabled/disabled
+ * individually.
+ *
+ * The control register has two event fields, one for each of the two
+ * counters.  It's thus nearly impossible to have one counter going
+ * while keeping the other one stopped.  Therefore it is possible to
+ * get overflow interrupts for counters not currently "in use" and
+ * that condition must be checked in the overflow interrupt handler.
+ *
+ * So we use a hack, in that we program inactive counters with the
+ * "sw_count0" and "sw_count1" events.  These count how many times
+ * the instruction "sethi %hi(0xfc000), %g0" is executed.  It's an
+ * unusual way to encode a NOP and therefore will not trigger in
+ * normal code.

Subject: microblaze: Improve checking mechanism for MSR instruction

It is more safe to use clear instead of msrset.
We save some instructions too.

Subject: perf: Tidy up after the big rename

 - provide compatibility Kconfig entry for existing PERF_COUNTERS .config's

 - provide courtesy copy of old perf_counter.h, for user-space projects

 - small indentation fixups

 - fix up MAINTAINERS

 - fix small x86 printout fallout

 - fix up small PowerPC comment fallout (use 'counter' as in register)

From d3a7dcfeeb6856215412065bd0f774de83f43414 Mon Sep 17 00:00:00 2001
From: Takashi Iwai <tiwai@suse.de>
Date: Thu, 17 Sep 2009 18:46:26 +0200
Subject: ALSA: pcm - Simplify snd_pcm_drain() implementation

Simplify snd_pcm_drain() implementation and avoid unneeded array-
allocation for waitqueues.  Instead, one waitqueue is used for the
first draining stream, and wait until all streams finished.

Signed-off-by: Takashi Iwai <tiwai@suse.de>

The documentation for /proc/sys/kernel/* does not mention the possible

between randomize-va-space, kernel parameter "norandmaps" and the

Subject: trivial: fix missing printk space in amd_k7_smp_check

This trivial patch fixes one missing space in printk.

I already fixed it about half a year ago or more, but the change (in
arch/x86/kernel/cpu/smpboot.c at that time) didn't made into
mainline yet.

Subject: trivial: doc: hpfall: reduce risk that hpfall can do harm

Improve the example code to be at least useable, as in not causing
harm (as shown below). Code can still be improved further, but this
adds some basic safeguards.

1. hpfall *MUST* mlockall(MCL_CURRENT|MCL_FUTURE); itself!
Since the Program sits and waits most of the time it becomes very likely
swapped out. If it gets woken up when the laptop drops from the table
while it is swapped out it actually triggers harddrive activity!

2. Daemonize hpfall using 'daemon(0,0)' (quick and dirty).

3. Give hpfall realtime priority.
Should give a chance that it has less latency when woken up.

Subject: trivial: doc: hpfall: accept disk device to unload as argument

Allows users who use an IDE driver for their disk to use hpfall without
having to modify the source. By default /dev/sda is used.
Suggested by Christian Thaeter in http://lkml.org/lkml/2009/3/25/505.

While we're add it, improve error message if opening /dev/freefall fails.

Currently it just sleeps for a very short time, just 1 jiffy. If
we keep looping in there, continually delay for a little longer
of up to 100msec in total. That was the old limit for congestion
wait.

Subject: nfs: initialize the backing_dev_info when creating the server

NFS may free the server structure without ever having used the
bdi, so we either need to flag the bdi as being uninitialized or
initialize it up front. This does the latter.

This fixes a crash with mounting more than one NFS file system,
should people ever need that kind of obscure NFS functionality.

Subject: Driver-Core: fix devnode callbacks for dabusb and industrialio

The build of the dabusb driver broke:

  drivers/media/video/dabusb.c:758: error: unknown field 'nodename' specified in initializer
  drivers/media/video/dabusb.c:758: warning: initialization from incompatible pointer type
  make[3]: *** wait: No child processes.  Stop.

Due to this commit:

  e454cea: Driver-Core: extend devnode callbacks to provide permissions

Missing the dabusb driver's dabusb_nodename() callback.

Similar issues with the iio/industrialio driver in staging, pointed out
and patched by Jean Delvare.

+
+	- gss support is questionable: currently mounts with kerberos

+	  conformant with the spec (for example, we don't use kerberos
+	  on the backchannel correctly).
+	- no trunking support: no clients currently take advantage of

+	  recommended to clients in a number of places.  (E.g. to ensure
+	  timely renewal in case an existing connection's retry timeouts
+	  have gotten too long; see section 8.3 of the draft.)
+	  Therefore, lack of this feature may cause future clients to
+	  fail.
+	- Incomplete backchannel support: incomplete backchannel gss
+	  support and no support for BACKCHANNEL_CTL mean that
+	  callbacks (hence delegations and layouts) may not be
+	  available and clients confused by the incomplete
+	  implementation may fail.
+	- Server reboot recovery is unsupported; if the server reboots,
+	  clients may fail.
+	- We do not support SSV, which provides security for shared
+	  client-server state (thus preventing unauthorized tampering
+	  with locks and opens, for example).  It is mandatory for
+	  servers to support this, though no clients use it yet.
+	- Mandatory operations which we do not support, such as
+	  DESTROY_CLIENTID, FREE_STATEID, SECINFO_NO_NAME, and
+	  TEST_STATEID, are not currently used by clients, but will be
+	  (and the spec recommends their uses in common cases), and
+	  clients should not be expected to know how to recover from the
+	  case where they are not supported.  This will eventually cause
+	  interoperability failures.
+
+In addition, some limitations are inherited from the current NFSv4

Subject: ARM: 5715/1: Make kprobes unregistration SMP safe

ARM kprobes use an illegal instruction to trigger kprobes. In the
current implementation, there's a race between the unregistration of a
kprobe and the illegal instruction exception handler if they run at the
same time on different cores.

When reading the value of the undefined instruction, the exception
handler might get the original legal instruction as just patched
concurrently by arch_disarm_kprobe(). When this happen the kprobe
handler won't run, and thus the exception handler will oops because it
believe it just hit an undefined instruction in kernel space.

The following patch synchronizes the code patching in the kprobes
unregistration using stop_machine and thus avoids the above race.

This removes the totally bogus bus ID:s with two-digit hex numerals

the device identifier as a string. I kept the "dev:" prefix for
DevChips, "fpga:" prefix for FPGA:s and "issp:" prefix for the
other processor bus, just in case someone likes them.

gcc-4.0, unlike gcc-4.3, does not see that these variables are
initialized before use.  Convert the descriptor loops to do-while make
this initialization apparent.

From ceb69a899f0819bce825083bd487c6afacc0d1b4 Mon Sep 17 00:00:00 2001
From: Mikael Pettersson <mikpe@it.uu.se>

Subject: ixp4xx: timer and clocks cleanups
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch does a few simple cleanups of the ixp4xx timer
and clocksource/clockevent code in mach-ixp4xx/common.c:

- ixp4xx_clocksource_init() is static and always returns 0,
  which is ignored by its only caller: make it return void
- ixp4xx_clockevent_init(): ditto
- ixp4xx_get_cycles() is only referenced locally: make it static
- use the ixp4xx_timer_irq.dev_id field to pass &clockevent_ixp4xx
  to ixp4xx_timer_interrupt() via its dev_id parameter, allowing
  the code in ixp4xx_timer_interrupt() to be smaller and faster

Tested on an ixp420 machine (ds101).

Subject: ixp4xx: arch_idle() documentation fixup
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The body of the mach-ixp4xx arch_idle() is mysteriously
disabled by an #if 0 .. #endif. Normally one would expect
to find a call to cpu_do_idle() there, but that call is
disabled, even though cpu_do_idle() is implemented for
XScale cores (and ixp4xx is one).

The explanation can be found in the ixp42x developer's manual
which states that the XScale core clock and power management
registers aren't implemented on ixp42x [3.5.2.2].

Also, the disabled code has suffered from bit rot:
- it checks hlt_counter which is obsolete, as that variable
  and all related code now is private to kernel/process.c
- it passes too many parameters to cpu_do_idle()

So this patch:
- adds a comment before the #if 0 to explain why
  cpu_do_idle() mustn't be called on ixp4xx
- removes the obsolete test of hlt_counter and the
  obsolete parameter to cpu_do_idle()

This is purely a documentation fixup and changes no
generated code. Even so, it has been tested on an
ixp420 machine (ds101).

Subject: ixgbe: Allow tx itr specific settings

Allow the user to set Tx specific itr values.  This only makes sense
when there are separate vectors for Tx and Rx.  When the queues are
doubled up RxTx on the vectors, we still only use the rx itr value.

Subject: Btrfs: speed up snapshot dropping

This patch contains two changes to avoid unnecessary tree block reads during
snapshot dropping.

First, check tree block's reference count and flags before reading the tree
block. if reference count > 1 and there is no need to update backrefs, we can
avoid reading the tree block.

Second, save when snapshot was created in root_key.offset. we can compare block
pointer's generation with snapshot's creation generation during updating
backrefs. If a given block was created before snapshot was created, the
snapshot can't be the tree block's owner. So we can avoid reading the block.

Subject: Btrfs: do not reuse objectid of deleted snapshot/subvol

The new back reference format does not allow reusing objectid of
deleted snapshot/subvol. So we use ++highest_objectid to allocate
objectid for new snapshot/subvol.

Now we use ++highest_objectid to allocate objectid for both new inode
and new snapshot/subvolume, so this patch removes 'find hole' code in
btrfs_find_free_objectid.

Subject: Btrfs: change how subvolumes are organized

btrfs allows subvolumes and snapshots anywhere in the directory tree.
If we snapshot a subvolume that contains a link to other subvolume
called subvolA, subvolA can be accessed through both the original
subvolume and the snapshot. This is similar to creating hard link to
directory, and has the very similar problems.

The aim of this patch is enforcing there is only one access point to
each subvolume. Only the first directory entry (the one added when
the subvolume/snapshot was created) is treated as valid access point.
The first directory entry is distinguished by checking root forward
reference. If the corresponding root forward reference is missing,
we know the entry is not the first one.

This patch also adds snapshot/subvolume rename support, the code
allows rename subvolume link across subvolumes.

Subject: Btrfs: add snapshot/subvolume destroy ioctl

This patch adds snapshot/subvolume destroy ioctl.  A subvolume that isn't being
used and doesn't contains links to other subvolumes can be destroyed.

Subject: backlight: Allow drivers to update the core, and generate events on
 changes

Certain hardware will send us events when the backlight brightness
changes. Add a function to update the value in the core, and
additionally send a uevent so that userspace can pop up appropriate
UI. The uevents are flagged depending on whether the update originated
in the kernel or from userspace, making it easier to only display UI
at the appropriate time.

Subject: xen: check EFER for NX before setting up GDT mapping

x86-64 assumes NX is available by default, so we need to
explicitly check for it before using NX.  Some first-generation
Intel x86-64 processors didn't support NX, and even recent systems
allow it to be disabled in BIOS.

[ Impact: prevent Xen crash on NX-less 64-bit machines ]

Subject: kmemcheck: add missing braces to do-while in
 kmemcheck_annotate_bitfield

Whether or not the sparse warning

	warning: do-while statement is not a compound statement

is justified or not in this case, it is annoying and trivial to fix.

Subject: drm/i915: split display functions by chip type

This patch splits out several of the display functions into a separate
display function table to avoid tons of chipset specific if..else
if..else if blocks all over.  There are more opportunities for this
(some noted in the structure defintition); so more cleanup patches will
follow.

From 74dff282237ea8c0a5df1afd8526eac4b6cee063 Mon Sep 17 00:00:00 2001
From: Jesse Barnes <jbarnes@virtuousgeek.org>
Date: Mon, 14 Sep 2009 15:39:40 -0700
Subject: drm/i915: framebuffer compression for GM45+

Add support for framebuffer compression on GM45 and above.  Removes
some unnecessary I915_HAS_FBC checks as well (this is now part of the
FBC display function).

From ba1bf4818baf68d914ef9e3b06fbea6acb674fe4 Mon Sep 17 00:00:00 2001

Subject: Btrfs: make balance code choose more wisely when relocating

Currently, we can panic the box if the first block group we go to move is of a
type where there is no space left to move those extents.  For example, if we
fill the disk up with data, and then we try to balance and we have no room to
move the data nor room to allocate new chunks, we will panic.  Change this by
checking to see if we have room to move this chunk around, and if not, return
-ENOSPC and move on to the next chunk.  This will make sure we remove block
groups that are moveable, like if we have alot of empty metadata block groups,
and then that way we make room to be able to balance our data chunks as well.
Tested this with an fs that would panic on btrfs-vol -b normally, but no longer
panics with this patch.

V1->V2:
-actually search for a free extent on the device to make sure we can allocate a
chunk if need be.

-fix btrfs_shrink_device to make sure we actually try to relocate all the
chunks, and then if we can't return -ENOSPC so if we are doing a btrfs-vol -r
we don't remove the device with data still on it.

-check to make sure the block group we are going to relocate isn't the last one
in that particular space

-fix a bug in btrfs_shrink_device where we would change the device's size and
not fix it if we fail to do our relocate

Subject: Btrfs: don't keep retrying a block group if we fail to allocate a
 cluster

The box can get locked up in the allocator if we happen upon a block group
under these conditions:

1) During a commit, so caching threads cannot make progress
2) Our block group currently is in the middle of being cached
3) Our block group currently has plenty of free space in it
4) Our block group is so fragmented that it ends up having no free space chunks
larger than min_bytes calculated by btrfs_find_space_cluster.

What happens is we try and do btrfs_find_space_cluster, which fails because it
is unable to find enough free space chunks that are large than min_bytes and
are close enough together.  Since the block group is not cached we do a
wait_block_group_cache_progress, which waits for the number of bytes we need,
except the block group already has _plenty_ of free space, its just severely
fragmented, so we loop and try again, ad infinitum.  This patch keeps us from
waiting on the block group to finish caching if we failed to find a free space
cluster before.  It also makes sure that we don't even try to find a free space
cluster if we are on our last loop in the allocator, since we will have tried
everything at this point at it is futile.

Subject: Btrfs: fix bitmap size tracking

When we first go to add free space, we allocate a new info and set the offset
and bytes to the space we are adding.  This is fine, except we actually set the
size of a bitmap as we set the bits in it, so if we add space to a bitmap, we'd
end up counting the same space twice.  This isn't a huge deal, it just makes
the allocator behave weirdly since it will think that a bitmap entry has more
space than it ends up actually having.  I used a BUG_ON() to catch when this
problem happened, and with this patch I no longer get the BUG_ON().

Subject: Btrfs: fix extent entry threshold calculation

There is a slight problem with the extent entry threshold calculation for the
free space cache.  We only adjust the threshold down as we add bitmaps, but
never actually adjust the threshold up as we add bitmaps.  This means we could
fragment the free space so badly that we end up using all bitmaps to describe
the free space, use all the free space which would result in the bitmaps being
freed, but then go to add free space again as we delete things and immediately
add bitmaps since the extent threshold would still be 0.  Now as we free
bitmaps the extent threshold will be ratcheted up to allow more extent entries
to be added.

Subject: Btrfs: account for space used by the super mirrors

As we get closer to proper -ENOSPC handling in btrfs, we need more accurate
space accounting for the space info's.  Currently we exclude the free space for
the super mirrors, but the space they take up isn't accounted for in any of the
counters.  This patch introduces bytes_super, which keeps track of the amount
of bytes used for a super mirror in the block group cache and space info.  This
makes sure that our free space caclucations will be completely accurate.

Subject: microblaze: Save and restore msr in hw exception

I thought that this part of code could be removed because just
save and restore MSR but any code can't change it. But seems to
that any part of code works with this information.

This patch solved problem with allocation.

Subject: perf_event, powerpc: Fix compilation after big perf_counter rename

This fixes two places in the powerpc perf_event (perf_counter) code
where 'list_entry' needs to be changed to 'group_entry', but were
missed in commit 65abc865 ("perf_counter: Rename list_entry ->
group_entry, counter_list -> group_list").

This also changes 'event' back to 'counter' in a couple of
contexts:

* Field and function names that deal with the limited-function
  counters: it's really the hardware counters whose function is
  limited, not the events that they count.  Hence:

  MAX_LIMITED_HWEVENTS -> MAX_LIMITED_HWCOUNTERS
  limited_event -> limited_counter
  freeze/thaw_limited_events -> freeze/thaw_limited_counters

* The machine-specific PMU description struct (struct power_pmu): this
  renames 'n_event' back to 'n_counter' since it really describes how
  many hardware counters the machine has.  (Renaming this back avoids
  a compile error in each of the machine-specific PMU back-ends where
  they initialize their power_pmu struct.)

LOAD_OFFSET is the offset between the physical load address and the kernel's

make sure that the LMAs of sections in vmlinux are correct.

Subject: microblaze: Use LOAD_OFFSET macro to get correct LMA for all sections

Currently, vmlinux has LMA==VMA for all sections, which is wrong for MMU
kernels.  Previous patches in this series defined the LOAD_OFFSET constant,
now we make use of it in our link script.

Other minor changes in this patch:
	* brace/indenting cleanup of some sections
	* put __fdt_* symbols in their own section, and apply LOAD_OFFSET fixup

Subject: microblaze: Fix _start symbol to physical address

_start is setup to physical kernel start address.
This caused that when you load vmlinux (with MMU kernel)
via XMD program counter (pc) is setup correctly
and then you can write con and start kernel.

Subject: futex: Correct futex_q woken state commentary

Use kernel-doc format to describe struct futex_q.

Correct the wakeup definition to eliminate the statement about
waking the waiter between the plist_del() and the q->lock_ptr = 0.

Note in the comment that PI futexes have a different definition of
the woken state.

Subject: futex: Fix wakeup race by setting TASK_INTERRUPTIBLE before
 queue_me()

PI futexes do not use the same plist_node_empty() test for wakeup.
It was possible for the waiter (in futex_wait_requeue_pi()) to set
TASK_INTERRUPTIBLE after the waker assigned the rtmutex to the
waiter. The waiter would then note the plist was not empty and call
schedule(). The task would not be found by any subsequeuent futex
wakeups, resulting in a userspace hang.

By moving the setting of TASK_INTERRUPTIBLE to before the call to
queue_me(), the race with the waker is eliminated. Since we no
longer call get_user() from within queue_me(), there is no need to
delay the setting of TASK_INTERRUPTIBLE until after the call to
queue_me().

The FUTEX_LOCK_PI operation is not affected as futex_lock_pi()
relies entirely on the rtmutex code to handle schedule() and
wakeup.  The requeue PI code is affected because the waiter starts
as a non-PI waiter and is woken on a PI futex.

Remove the crusty old comment about holding spinlocks() across
get_user() as we no longer do that. Correct the locking statement
with a description of why the test is performed.

Subject: regulator: Allow consumer supplies to be set up with dev_name()

Follow the approach suggested by Russell King and implemented by him in
the clkdev API and allow consumer device supply mapings to be set up
using the dev_name() for the consumer instead of the struct device.
In order to avoid making existing machines instabuggy and creating merge
issues the use of struct device is still supported for the time being.

This resolves problems working with buses such as I2C which make the
struct device available late providing that the final device name is
known, which is the case for most embedded systems with fixed setups.

Consumers must still use the struct device when calling regulator_get().

Subject: regulator: replace ADTV1 register by ADTV2 in da903x

In PXA3xx SoC family, V_CORE power doamin is supplied by BUCK1 that is
controller by ADTV1 or ADTV2 register.

By default, v1 and v2 has the same copy. If v1 or v2 is updated, the last
value that is written to either register takes effect. It means that v1
and v2 has different copy. And the actual voltage output is determinated
by last update on either register.

DA9034/35 is binded with PXA3xx SoC family. While SoC is scaling OP or
entering/exiting lower power mode, SoC needs to change voltage of V_CORE
power doamin. In order to be efficient, POWER I2C (hardcode) mode could
be enabled in SoC. In this mode, SoC will control v2 register directly.

In original DA903x driver, software will only read regulator data from v1
register. But SoC controls v2 register directly. It results that v1 and v2
isn't synchronized. Wrong data will be read from v1 register. So access v2
register in da903x driver instead.

Subject: regulator: Add regulator_get_exclusive() API

Some consumers require complete control of the regulator and can't
tolerate sharing it with other consumers, most commonly because they need
to have the regulator actually disabled so can't have other consumers
forcing it on. This new regulator_get_exclusive() API call allows these
consumers to explicitly request this, documenting the assumptions that
they are making.

In order to simplify coding of such consumers the use count for regulators
they request is forced to match the enabled state of the regulator when
it is requested. This is not possible for consumers which can share
regulators due to the need to keep track of the ownership of use counts.

A new API call is used rather than an additional argument to the existing
regulator_get() in order to avoid merge headaches with driver code in
other trees.

Subject: regulator: Fix support for deviceless supply mappings

The patch to add support for looking up consumers by device name
had the side effect of causing us to require a device which is
at best premature since at least cpufreq still operates outside
the device model. Remove that requirement.

Subject: regulator: regulator_enable() permission checking

The regulator_enable() code wasn't actually checking that the
machine constraints had given permission to enable the regulator.
Add code to do that, but only if the regulator is not already on
due to something like always_on or being left on at startup since
in those cases there's no physical change being introduced and the
constraint wouldn't make any sense.

Also add matching code for disable(). We need to do less there since
either regulator_enable() should have succeeded first or the board
setup makes no sense.

Subject: Regulator: Implement list_voltage for pcf50633 regulator driver.

This patch implements list_voltage for the pcf50644 regulator driver.
As the voltages are linearly scaled the code to convert register values to
voltages can be reused and most of the code can be shared with get_voltage.

Subject: regulator: Add GPIO enable control to fixed voltage regulator driver

Now fixed regulators that have their enable pin connected to a GPIO line
can use the fixed regulator driver for regulator enable/disable control.
The GPIO number and polarity information is passed through platform data.
GPIO enable control is achieved using gpiolib.

0x74 0x70 0x73 0x36 0x35 0x30 0x32 0x33 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00
FATAL: drivers/regulator/tps65023-regulator: struct i2c_device_id is not terminated with a NULL entry!

This patch also fixes the GPL v2 licence string for both drivers.

This makes _regulator_enable() properly handle the case where
a regulator is already on when you try to enable it. Currently
it will erroneously handle positive return values as an error.

Subject: fs: make sure data stored into inode is properly seen before
 unlocking new inode

In theory it could happen that on one CPU we initialize a new inode but
clearing of I_NEW | I_LOCK gets reordered before some of the
initialization.  Thus on another CPU we return not fully uptodate inode
from iget_locked().

This seems to fix a corruption issue on ext3 mounted over NFS.

[akpm@linux-foundation.org: add some commentary]

Subject: mm: remove obsoleted alloc_pages cpuset comment

When a cpuset's nodemask is updated, all attached tasks have their cached
task->mems_allowed updated by a heap instead of requiring an explicit call
to cpuset_update_task_memory_state(), which has since been removed in
58568d2a8215cb6f55caf2332017d7bdff954e1c ("cpuset,mm: update tasks'
mems_allowed in time").

Remove the obsoleted comment from the page allocator.

Subject: memory hotplug: exclude isolated page from pco page alloc

Pages marked as isolated should not be allocated again.  If such pages
reside in pcp list, they can be allocated too, so there is a ping-pong
memory offline frees some pages to pcp list and the pages get allocated
and then memory offline frees them again, this loop will happen again and
again.

This should have no impact in normal code path, because in normal code
path, pages in pcp list aren't isolated, and below loop will break in the
first entry.

Pages on movable zone have two types, MIGRATE_MOVABLE and MIGRATE_RESERVE,
both them can be movable, because only movable memory allocation can get
pages from movable zone.  This makes pages in movable zone always be able
to migrate.

Subject: memory hotplug: migrate swap cache page

In test, some pages in swap-cache can't be migrated, as they aren't rmap.

unmap_and_move() ignores swap-cache page which is just read in and hasn't
rmap (see the comments in the code), but swap_aops provides .migratepage.
Better to migrate such pages instead of ignore them.

Subject: hugetlb: balance freeing of huge pages across nodes

Free huges pages from nodes in round robin fashion in an attempt to keep
[persistent a.k.a static] hugepages balanced across nodes

New function free_pool_huge_page() is modeled on and performs roughly the
inverse of alloc_fresh_huge_page().  Replaces dequeue_huge_page() which
now has no callers, so this patch removes it.

Helper function hstate_next_node_to_free() uses new hstate member
next_to_free_nid to distribute "frees" across all nodes with huge pages.

Subject: hugetlb: use free_pool_huge_page() to return unused surplus pages

Use the [modified] free_pool_huge_page() function to return unused
surplus pages.  This will help keep huge pages balanced across nodes
between freeing of unused surplus pages and freeing of persistent huge
pages [from set_max_huge_pages] by using the same node id "cursor". It
also eliminates some code duplication.

Subject: hugetlb: restore interleaving of bootmem huge pages

I noticed that alloc_bootmem_huge_page() will only advance to the next
node on failure to allocate a huge page, potentially filling nodes with
huge-pages.  I asked about this on linux-mm and linux-numa, cc'ing the
usual huge page suspects.

Mel Gorman responded:

	I strongly suspect that the same node being used until allocation
	failure instead of round-robin is an oversight and not deliberate
	at all. It appears to be a side-effect of a fix made way back in
	commit 63b4613c3f0d4b724ba259dc6c201bb68b884e1a ["hugetlb: fix
	hugepage allocation with memoryless nodes"]. Prior to that patch
	it looked like allocations would always round-robin even when
	allocation was successful.

This patch--factored out of my "hugetlb mempolicy" series--moves the
advance of the hstate next node from which to allocate up before the test
for success of the attempted allocation.

Note that alloc_bootmem_huge_page() is only used for order > MAX_ORDER
huge pages.

I'll post a separate patch for mainline/stable, as the above mentioned
"balance freeing" series renamed the next node to alloc function.

Subject: mm: oom analysis: add shmem vmstat

Recently we encountered OOM problems due to memory use of the GEM cache.
Generally a large amuont of Shmem/Tmpfs pages tend to create a memory
shortage problem.

We often use the following calculation to determine the amount of shmem
pages:

shmem = NR_ACTIVE_ANON + NR_INACTIVE_ANON - NR_ANON_PAGES

however the expression does not consider isolated and mlocked pages.

This patch adds explicit accounting for pages used by shmem and tmpfs.

Subject: mm: update alloc_flags after oom killer has been called

It is possible for the oom killer to select current as the task to kill.
When this happens, alloc_flags needs to be updated accordingly to set
ALLOC_NO_WATERMARKS so the subsequent allocation attempt may use memory
reserves as the result of its thread having TIF_MEMDIE set if the
allocation is not __GFP_NOMEMALLOC.

Subject: mm: shrink_inactive_list() nr_scan accounting fix fix

If sc->isolate_pages() return 0, we don't need to call shrink_page_list().
In past days, shrink_inactive_list() handled it properly.

But commit fb8d14e1 (three years ago commit!) breaked it.  current
shrink_inactive_list() always call shrink_page_list() although
isolate_pages() return 0.

This patch restore proper return value check.

Requirements:
  o "nr_taken == 0" condition should stay before calling shrink_page_list().
  o "nr_taken == 0" condition should stay after nr_scan related statistics
     modification.

Subject: mm: vmstat: add isolate pages

If the system is running a heavy load of processes then concurrent reclaim
can isolate a large number of pages from the LRU. /proc/vmstat and the
output generated for an OOM do not show how many pages were isolated.

This has been observed during process fork bomb testing (mstctl11 in LTP).

This patch shows the information about isolated pages.

Reproduced via:

-----------------------
% ./hackbench 140 process 1000
   => OOM occur

active_anon:146 inactive_anon:0 isolated_anon:49245
 active_file:79 inactive_file:18 isolated_file:113
 unevictable:0 dirty:0 writeback:0 unstable:0 buffer:39
 free:370 slab_reclaimable:309 slab_unreclaimable:5492

Subject: vmscan: throttle direct reclaim when too many pages are isolated
 already

When way too many processes go into direct reclaim, it is possible for all
of the pages to be taken off the LRU.  One result of this is that the next
process in the page reclaim code thinks there are no reclaimable pages
left and triggers an out of memory kill.

One solution to this problem is to never let so many processes into the
page reclaim path that the entire LRU is emptied.  Limiting the system to
only having half of each inactive list isolated for reclaim should be
safe.

Subject: mm: count only reclaimable lru pages

global_lru_pages() / zone_lru_pages() can be used in two ways:
- to estimate max reclaimable pages in determine_dirtyable_memory()
- to calculate the slab scan ratio

When swap is full or not present, the anon lru lists are not reclaimable
and also won't be scanned.  So the anon pages shall not be counted in both
usage scenarios.  Also rename to _reclaimable_pages: now they are counting
the possibly reclaimable lru pages.

It can greatly (and correctly) increase the slab scan rate under high
memory pressure (when most file pages have been reclaimed and swap is
full/absent), thus reduce false OOM kills.

The VM already avoids attempting to reclaim anon pages in various places,
But it doesn't avoid it for lumpy reclaim.

It shuffles lru list unnecessary so that it is pointless.

Subject: vmscan: kill unnecessary prefetch

The pages in the list passed move_active_pages_to_lru() are already
touched by shrink_active_list().  IOW the prefetch in
move_active_pages_to_lru() don't populate any cache.  it's pointless.

This patch remove it.

Subject: mm: perform non-atomic test-clear of PG_mlocked on free

By the time PG_mlocked is cleared in the page freeing path, nobody else is
looking at our page->flags anymore.

It is thus safe to make the test-and-clear non-atomic and thereby removing
an unnecessary and expensive operation from a hotpath.

Subject: ksm: add mmu_notifier set_pte_at_notify()

KSM is a linux driver that allows dynamicly sharing identical memory pages
between one or more processes.

Unlike tradtional page sharing that is made at the allocation of the
memory, ksm do it dynamicly after the memory was created.  Memory is
periodically scanned; identical pages are identified and merged.

The sharing is made in a transparent way to the processes that use it.

Ksm is highly important for hypervisors (kvm), where in production
enviorments there might be many copys of the same data data among the host
memory.  This kind of data can be: similar kernels, librarys, cache, and
so on.

Even that ksm was wrote for kvm, any userspace application that want to
use it to share its data can try it.

Ksm may be useful for any application that might have similar (page
aligment) data strctures among the memory, ksm will find this data merge
it to one copy, and even if it will be changed and thereforew copy on
writed, ksm will merge it again as soon as it will be identical again.

Another reason to consider using ksm is the fact that it might simplify
alot the userspace code of application that want to use shared private
data, instead that the application will mange shared area, ksm will do
this for the application, and even write to this data will be allowed
without any synchinization acts from the application.

Ksm was designed to be a loadable module that doesn't change the VM code
of linux.

This patch:

The set_pte_at_notify() macro allows setting a pte in the shadow page
table directly, instead of flushing the shadow page table entry and then
getting vmexit to set it.  It uses a new change_pte() callback to do so.

set_pte_at_notify() is an optimization for kvm, and other users of
mmu_notifiers, for COW pages.  It is useful for kvm when ksm is used,
because it allows kvm not to have to receive vmexit and only then map the
ksm page into the shadow page table, but instead map it directly at the
same time as Linux maps the page into the host page table.

Users of mmu_notifiers who don't implement new mmu_notifier_change_pte()
callback will just receive the mmu_notifier_invalidate_page() callback.

Subject: ksm: first tidy up madvise_vma()

madvise.c has several levels of switch statements, what to do in which?
Move MADV_DOFORK code down from madvise_vma() to madvise_behavior(), so
madvise_vma() can be a simple router, to madvise_behavior() by default.

vma->vm_flags is an unsigned long so use the same type for new_flags.  Add
missing comment lines to describe MADV_DONTFORK and MADV_DOFORK.

Subject: ksm: define MADV_MERGEABLE and MADV_UNMERGEABLE

The out-of-tree KSM used ioctls on fds cloned from /dev/ksm to register a
memory area for merging: we prefer now to use an madvise(2) interface.

This patch just defines MADV_MERGEABLE (to tell KSM it may merge pages in
this area found identical to pages in other mergeable areas) and
MADV_UNMERGEABLE (to undo that).

Most architectures use asm-generic, but alpha, mips, parisc, xtensa need
their own definitions: included here for mmotm convenience, but we'll
probably want to split this and feed pieces to arch maintainers.

Based upon earlier patches by Chris Wright and Izik Eidus.

Subject: ksm: the mm interface to ksm

This patch presents the mm interface to a dummy version of ksm.c, for
better scrutiny of that interface: the real ksm.c follows later.

When CONFIG_KSM is not set, madvise(2) reject MADV_MERGEABLE and
MADV_UNMERGEABLE with EINVAL, since that seems more helpful than
pretending that they can be serviced.  But when CONFIG_KSM=y, accept them
even if KSM is not currently running, and even on areas which KSM will not
touch (e.g.  hugetlb or shared file or special driver mappings).

Like other madvices, report ENOMEM despite success if any area in the
range is unmapped, and use EAGAIN to report out of memory.

Define vma flag VM_MERGEABLE to identify an area on which KSM may try
merging pages: leave it to ksm_madvise() to decide whether to set it.
Define mm flag MMF_VM_MERGEABLE to identify an mm which might contain
VM_MERGEABLE areas, to minimize callouts when forking or exiting.

Based upon earlier patches by Chris Wright and Izik Eidus.

Subject: ksm: no debug in page_dup_rmap()

page_dup_rmap(), used on each mapped page when forking, was originally
just an inline atomic_inc of mapcount.  2.6.22 added CONFIG_DEBUG_VM
out-of-line checks to it, which would need to be ever-so-slightly
complicated to allow for the PageKsm() we're about to define.

But I think these checks never caught anything.  And if it's coding errors
we're worried about, such checks should be in page_remove_rmap() too, not
just when forking; whereas if it's pagetable corruption we're worried
about, then they shouldn't be limited to CONFIG_DEBUG_VM.

Oh, just revert page_dup_rmap() to an inline atomic_inc of mapcount.

Subject: ksm: identify PageKsm pages

KSM will need to identify its kernel merged pages unambiguously, and
/proc/kpageflags will probably like to do so too.

Since KSM will only be substituting anonymous pages, statistics are best
preserved by making a PageKsm page a special PageAnon page: one with no
anon_vma.

But KSM then needs its own page_add_ksm_rmap() - keep it in ksm.h near
PageKsm; and do_wp_page() must COW them, unlike singly mapped PageAnons.

Subject: ksm: Kernel SamePage Merging

Ksm is code that allows merging of identical pages between one or more
applications, in a way invisible to the applications that use it.  Pages
that are merged are marked as read-only, then COWed when any application
tries to change them.

Whereas fork() allows sharing anonymous pages between parent and child,
ksm can share anonymous pages between unrelated processes.

Ksm works by walking over the memory pages of the applications it scans,
in order to find identical pages.  It uses two sorted data structures,
called the stable and unstable trees, to locate identical pages in an
effective way.

When ksm finds two identical pages, it marks them as readonly and merges
them into a single page.  After the pages have been marked as readonly and
merged into one, Linux treats them as normal copy-on-write pages, copying
to a fresh anonymous page if write access is required later.

Ksm scans and merges anonymous pages only in those memory areas that have
been registered with it by madvise(addr, length, MADV_MERGEABLE).

The ksm scanner is controlled by sysfs files in /sys/kernel/mm/ksm/:

max_kernel_pages - the maximum number of unswappable kernel pages
                   which may be allocated by ksm (0 for unlimited).

kernel_pages_allocated - how many ksm pages are currently allocated,
                         sharing identical content between different
                         processes (pages unswappable in this release).

pages_shared - how many pages have been saved by sharing with ksm pages
               (kernel_pages_allocated being excluded from this count).

pages_to_scan - how many pages ksm should scan before sleeping.

sleep_millisecs - how many milliseconds ksm should sleep between scans.

run - write 0 to disable ksm, read 0 while ksm is disabled (default),
      write 1 to run ksm, read 1 while ksm is running,
      write 2 to disable ksm and unmerge all its pages.

+ * A few notes about the KSM scanning process,
+ * to make it easier to understand the data structures below:
+ *
+ * In order to reduce excessive scanning, KSM sorts the memory pages by their
+ * contents into a data structure that holds pointers to the pages' locations.
+ *
+ * Since the contents of the pages may change at any moment, KSM cannot just
+ * insert the pages into a normal sorted tree and expect it to find anything.
+ * Therefore KSM uses two data structures - the stable and the unstable tree.
+ *
+ * The stable tree holds pointers to all the merged pages (ksm pages), sorted
+ * by their contents.  Because each such page is write-protected, searching on
+ * this tree is fully assured to be working (except when pages are unmapped),
+ * and therefore this tree is called the stable tree.
+ *
+ * In addition to the stable tree, KSM uses a second data structure called the
+ * unstable tree: this tree holds pointers to pages which have been found to
+ * be "unchanged for a period of time".  The unstable tree sorts these pages
+ * by their contents, but since they are not write-protected, KSM cannot rely
+ * upon the unstable tree to work correctly - the unstable tree is liable to
+ * be corrupted as its contents are modified, and so it is called unstable.
+ *
+ * KSM solves this problem by several techniques:
+ *
+ * 1) The unstable tree is flushed every time KSM completes scanning all
+ *    memory areas, and then the tree is rebuilt again from the beginning.
+ * 2) KSM will only insert into the unstable tree, pages whose hash value
+ *    has not changed since the previous scan of all memory areas.
+ * 3) The unstable tree is a RedBlack Tree - so its balancing is based on the
+ *    colors of the nodes and not on their contents, assuring that even when
+ *    the tree gets "corrupted" it won't get out of balance, so scanning time
+ *    remains the same (also, searching and inserting nodes in an rbtree uses
+ *    the same algorithm, so we have no overhead when we flush and rebuild).
+ * 4) KSM never flushes the stable tree, which means that even if it were to
+ *    take 10 attempts to find a page in the unstable tree, once it is found,
+ *    it is secured in the stable tree.  (When we scan a new page, we first
+ *    compare it against the stable tree, and then against the unstable tree.)

Subject: ksm: prevent mremap move poisoning

KSM's scan allows for user pages to be COWed or unmapped at any time,
without requiring any notification.  But its stable tree does assume that
when it finds a KSM page where it placed a KSM page, then it is the same
KSM page that it placed there.

mremap move could break that assumption: if an area containing a KSM page
was unmapped, then an area containing a different KSM page was moved with
mremap into the place of the original, before KSM's scan came around to
notice.  That could then poison a node of the stable tree, so that memcmps
would "lie" and upset the ordering of the tree.

Probably noone will ever need mremap move on a VM_MERGEABLE area; except
that prohibiting it would make trouble for schemes in which we try making
everything VM_MERGEABLE e.g.  for testing: an mremap which normally works
would then fail mysteriously.

There's no need to go to any trouble, such as re-sorting KSM's list of
rmap_items to match the new layout: simply unmerge the area to COW all its
KSM pages before moving, but leave VM_MERGEABLE on so that they're
remerged later.

Subject: ksm: rename kernel_pages_allocated

We're not implementing swapping of KSM pages in its first release;
but when that follows, "kernel_pages_allocated" will be a very poor
name for the sysfs file showing number of nodes in the stable tree:
rename that to "pages_shared" throughout.

But we already have a "pages_shared", counting those page slots
sharing the shared pages: first rename that to... "pages_sharing".

What will become of "max_kernel_pages" when the pages shared can
be swapped?  I guess it will just be removed, so keep that name.

Subject: ksm: move pages_sharing updates

The pages_shared count is incremented and decremented when adding a node
to and removing a node from the stable tree: easy to understand.  But the
pages_sharing count was hard to follow, being adjusted in various places:
increment and decrement it when adding to and removing from the stable tree.

And the pages_sharing variable used to include the pages_shared, then those
were subtracted when shown in the pages_sharing sysfs file: now keep it as
an exclusive count of leaves hanging off the stable tree nodes, throughout.

Subject: ksm: pages_unshared and pages_volatile

The pages_shared and pages_sharing counts give a good picture of how
successful KSM is at sharing; but no clue to how much wasted work it's
doing to get there.  Add pages_unshared (count of unique pages waiting
in the unstable tree, hoping to find a mate) and pages_volatile.

pages_volatile is harder to define.  It includes those pages changing
too fast to get into the unstable tree, but also whatever other edge
conditions prevent a page getting into the trees: a high value may
deserve investigation.  Don't try to calculate it from the various
conditions: it's the total of rmap_items less those accounted for.

Also show full_scans: the number of completed scans of everything
registered in the mm list.

The locking for all these counts is simply ksm_thread_mutex.

Subject: ksm: break cow once unshared

We kept agreeing not to bother about the unswappable shared KSM pages
which later become unshared by others: observation suggests they're not
a significant proportion.  But they are disadvantageous, and it is easier
to break COW to replace them by swappable pages, than offer statistics
to show that they don't matter; then we can stop worrying about them.

Doing this in ksm_do_scan, they don't go through cmp_and_merge_page on
this pass: give them a good chance of getting into the unstable tree
on the next pass, or back into the stable, by computing checksum now.

Subject: ksm: keep quiet while list empty

ksm_scan_thread already sleeps in wait_event_interruptible until setting
ksm_run activates it; but if there's nothing on its list to look at, i.e.
nobody has yet said madvise MADV_MERGEABLE, it's a shame to be clocking
up system time and full_scans: ksmd_should_run added to check that too.

And move the mutex_lock out around it: the new counts showed that when
ksm_run is stopped, a little work often got done afterwards, because it
had been read before taking the mutex.

Subject: ksm: five little cleanups

1. We don't use __break_cow entry point now: merge it into break_cow.
2. remove_all_slot_rmap_items is just a special case of
   remove_trailing_rmap_items: use the latter instead.
3. Extend comment on unmerge_ksm_pages and rmap_items.
4. try_to_merge_two_pages should use try_to_merge_with_ksm_page
   instead of duplicating its code; and so swap them around.
5. Comment on cmp_and_merge_page described last year's: update it.

Subject: ksm: fix endless loop on oom

break_ksm has been looping endlessly ignoring VM_FAULT_OOM: that should
only be a problem for ksmd when a memory control group imposes limits
(normally the OOM killer will kill others with an mm until it succeeds);
but in general (especially for MADV_UNMERGEABLE and KSM_RUN_UNMERGE) we
do need to route the error (or kill) back to the caller (or sighandling).

Test signal_pending in unmerge_ksm_pages, which could be a lengthy
procedure if it has to spill into swap: returning -ERESTARTSYS so that
trivial signals will restart but fatals will terminate (is that right?
we do different things in different places in mm, none exactly this).

unmerge_and_remove_all_rmap_items was forgetting to lock when going
down the mm_list: fix that.  Whether it's successful or not, reset
ksm_scan cursor to head; but only if it's successful, reset seqnr
(shown in full_scans) - page counts will have gone down to zero.

This patch leaves a significant OOM deadlock, but it's a good step
on the way, and that deadlock is fixed in a subsequent patch.

Subject: ksm: distribute remove_mm_from_lists

Do some housekeeping in ksm.c, to help make the next patch easier
to understand: remove the function remove_mm_from_lists, distributing
its code to its callsites scan_get_next_rmap_item and __ksm_exit.

That turns out to be a win in scan_get_next_rmap_item: move its
remove_trailing_rmap_items and cursor advancement up, and it becomes
simpler than before.  __ksm_exit becomes messier, but will change
again; and moving its remove_trailing_rmap_items up lets us strengthen
the unstable tree item's age condition in remove_rmap_item_from_tree.

Subject: ksm: fix oom deadlock

There's a now-obvious deadlock in KSM's out-of-memory handling:
imagine ksmd or KSM_RUN_UNMERGE handling, holding ksm_thread_mutex,
trying to allocate a page to break KSM in an mm which becomes the
OOM victim (quite likely in the unmerge case): it's killed and goes
to exit, and hangs there waiting to acquire ksm_thread_mutex.

Clearly we must not require ksm_thread_mutex in __ksm_exit, simple
though that made everything else: perhaps use mmap_sem somehow?
And part of the answer lies in the comments on unmerge_ksm_pages:
__ksm_exit should also leave all the rmap_item removal to ksmd.

But there's a fundamental problem, that KSM relies upon mmap_sem to
guarantee the consistency of the mm it's dealing with, yet exit_mmap
tears down an mm without taking mmap_sem.  And bumping mm_users won't
help at all, that just ensures that the pages the OOM killer assumes
are on their way to being freed will not be freed.

The best answer seems to be, to move the ksm_exit callout from just
before exit_mmap, to the middle of exit_mmap: after the mm's pages
have been freed (if the mmu_gather is flushed), but before its page
tables and vma structures have been freed; and down_write,up_write
mmap_sem there to serialize with KSM's own reliance on mmap_sem.

But KSM then needs to be careful, whenever it downs mmap_sem, to
check that the mm is not already exiting: there's a danger of using
find_vma on a layout that's being torn apart, or writing into page
tables which have been freed for reuse; and even do_anonymous_page
and __do_fault need to check they're not being called by break_ksm
to reinstate a pte after zap_pte_range has zapped that page table.

Though it might be clearer to add an exiting flag, set while holding
mmap_sem in __ksm_exit, that wouldn't cover the issue of reinstating
a zapped pte.  All we need is to check whether mm_users is 0 - but
must remember that ksmd may detect that before __ksm_exit is reached.
So, ksm_test_exit(mm) added to comment such checks on mm->mm_users.

__ksm_exit now has to leave clearing up the rmap_items to ksmd,
that needs ksm_thread_mutex; but shift the exiting mm just after the
ksm_scan cursor so that it will soon be dealt with.  __ksm_enter raise
mm_count to hold the mm_struct, ksmd's exit processing (exactly like
its processing when it finds all VM_MERGEABLEs unmapped) mmdrop it,
similar procedure for KSM_RUN_UNMERGE (which has stopped ksmd).

But also give __ksm_exit a fast path: when there's no complication
(no rmap_items attached to mm and it's not at the ksm_scan cursor),
it can safely do all the exiting work itself.  This is not just an
optimization: when ksmd is not running, the raised mm_count would
otherwise leak mm_structs.

Subject: ksm: fix deadlock with munlock in exit_mmap

Rawhide users have reported hang at startup when cryptsetup is run: the
same problem can be simply reproduced by running a program int main() {
mlockall(MCL_CURRENT | MCL_FUTURE); return 0; }

The problem is that exit_mmap() applies munlock_vma_pages_all() to
clean up VM_LOCKED areas, and its current implementation (stupidly)
tries to fault in absent pages, for example where PROT_NONE prevented
them being faulted in when mlocking.  Whereas the "ksm: fix oom
deadlock" patch, knowing there's a race by which KSM might try to fault
in pages after exit_mmap() had finally zapped the range, backs out of
such faults doing nothing when its ksm_test_exit() notices mm_users 0.

So revert that part of "ksm: fix oom deadlock" which moved the
ksm_exit() call from before exit_mmap() to the middle of exit_mmap();
and remove those ksm_test_exit() checks from the page fault paths, so
allowing the munlocking to proceed without interference.

ksm_exit, if there are rmap_items still chained on this mm slot, takes
mmap_sem write side: so preventing KSM from working on an mm while
exit_mmap runs.  And KSM will bail out as soon as it notices that
mm_users is already zero, thanks to its internal ksm_test_exit checks.
So that when a task is killed by OOM killer or the user, KSM will not
indefinitely prevent it from running exit_mmap to release its memory.

This does break a part of what "ksm: fix oom deadlock" was trying to
achieve.  When unmerging KSM (echo 2 >/sys/kernel/mm/ksm), and even
when ksmd itself has to cancel a KSM page, it is possible that the
first OOM-kill victim would be the KSM process being faulted: then its
memory won't be freed until a second victim has been selected (freeing
memory for the unmerging fault to complete).

But the OOM killer is already liable to kill a second victim once the
intended victim's p->mm goes to NULL: so there's not much point in
rejecting this KSM patch before fixing that OOM behaviour.  It is very
much more important to allow KSM users to boot up, than to haggle over
an unlikely and poorly supported OOM case.

We also intend to fix munlocking to not fault pages: at which point
this patch _could_ be reverted; though that would be controversial, so
we hope to find a better solution.

Subject: ksm: sysfs and defaults

At present KSM is just a waste of space if you don't have CONFIG_SYSFS=y
to provide the /sys/kernel/mm/ksm files to tune and activate it.

Make KSM depend on SYSFS?  Could do, but it might be better to provide
some defaults so that KSM works out-of-the-box, ready for testers to
madvise MADV_MERGEABLE, even without SYSFS.

Though anyone serious is likely to want to retune the numbers to their
taste once they have experience; and whether these settings ever reach
2.6.32 can be discussed along the way.

Save 1kB from tiny kernels by #ifdef'ing the SYSFS side of it.

+How to use the Kernel Samepage Merging feature
+----------------------------------------------
+
+KSM is a memory-saving de-duplication feature, enabled by CONFIG_KSM=y,
+added to the Linux kernel in 2.6.32.  See mm/ksm.c for its implementation,
+and http://lwn.net/Articles/306704/ and http://lwn.net/Articles/330589/
+
+The KSM daemon ksmd periodically scans those areas of user memory which
+have been registered with it, looking for pages of identical content which
+can be replaced by a single write-protected page (which is automatically
+copied if a process later wants to update its content).
+
+KSM was originally developed for use with KVM (where it was known as
+Kernel Shared Memory), to fit more virtual machines into physical memory,
+by sharing the data common between them.  But it can be useful to any
+application which generates many instances of the same data.
+
+KSM only merges anonymous (private) pages, never pagecache (file) pages.
+KSM's merged pages are at present locked into kernel memory for as long
+as they are shared: so cannot be swapped out like the user pages they
+replace (but swapping KSM pages should follow soon in a later release).
+
+KSM only operates on those areas of address space which an application
+has advised to be likely candidates for merging, by using the madvise(2)
+system call: int madvise(addr, length, MADV_MERGEABLE).
+
+The app may call int madvise(addr, length, MADV_UNMERGEABLE) to cancel
+that advice and restore unshared pages: whereupon KSM unmerges whatever
+it merged in that range.  Note: this unmerging call may suddenly require
+more memory than is available - possibly failing with EAGAIN, but more
+probably arousing the Out-Of-Memory killer.
+
+If KSM is not configured into the running kernel, madvise MADV_MERGEABLE
+and MADV_UNMERGEABLE simply fail with EINVAL.  If the running kernel was
+built with CONFIG_KSM=y, those calls will normally succeed: even if the
+the KSM daemon is not currently running, MADV_MERGEABLE still registers
+the range for whenever the KSM daemon is started; even if the range
+cannot contain any pages which KSM could actually merge; even if
+MADV_UNMERGEABLE is applied to a range which was never MADV_MERGEABLE.
+
+Like other madvise calls, they are intended for use on mapped areas of
+the user address space: they will report ENOMEM if the specified range
+includes unmapped gaps (though working on the intervening mapped areas),
+and might fail with EAGAIN if not enough memory for internal structures.
+
+Applications should be considerate in their use of MADV_MERGEABLE,
+restricting its use to areas likely to benefit.  KSM's scans may use
+a lot of processing power, and its kernel-resident pages are a limited
+resource.  Some installations will disable KSM for these reasons.
+
+The KSM daemon is controlled by sysfs files in /sys/kernel/mm/ksm/,
+readable by all but writable only by root:
+
+max_kernel_pages - set to maximum number of kernel pages that KSM may use
+                   e.g. "echo 2000 > /sys/kernel/mm/ksm/max_kernel_pages"
+                   Value 0 imposes no limit on the kernel pages KSM may use;
+                   but note that any process using MADV_MERGEABLE can cause
+                   KSM to allocate these pages, unswappable until it exits.
+                   Default: 2000 (chosen for demonstration purposes)
+
+pages_to_scan    - how many present pages to scan before ksmd goes to sleep
+                   e.g. "echo 200 > /sys/kernel/mm/ksm/pages_to_scan"
+                   Default: 200 (chosen for demonstration purposes)
+
+sleep_millisecs  - how many milliseconds ksmd should sleep before next scan
+                   e.g. "echo 20 > /sys/kernel/mm/ksm/sleep_millisecs"
+                   Default: 20 (chosen for demonstration purposes)
+
+run              - set 0 to stop ksmd from running but keep merged pages,
+                   set 1 to run ksmd e.g. "echo 1 > /sys/kernel/mm/ksm/run",
+                   set 2 to stop ksmd and unmerge all pages currently merged,
+                         but leave mergeable areas registered for next run
+                   Default: 1 (for immediate use by apps which register)
+
+The effectiveness of KSM and MADV_MERGEABLE is shown in /sys/kernel/mm/ksm/:
+
+pages_shared     - how many shared unswappable kernel pages KSM is using
+pages_sharing    - how many more sites are sharing them i.e. how much saved
+pages_unshared   - how many pages unique but repeatedly checked for merging
+pages_volatile   - how many pages changing too fast to be placed in a tree
+full_scans       - how many times all mergeable areas have been scanned
+
+A high ratio of pages_sharing to pages_shared indicates good sharing, but
+a high ratio of pages_unshared to pages_sharing indicates wasted effort.
+pages_volatile embraces several different kinds of activity, but a high
+proportion there would also indicate poor use of madvise MADV_MERGEABLE.

Subject: ksm: remove VM_MERGEABLE_FLAGS

KSM originally stood for Kernel Shared Memory: but the kernel has long
supported shared memory, and VM_SHARED and VM_MAYSHARE vmas, and KSM is
something else.  So we switched to saying "merge" instead of "share".

But Chris Wright points out that this is confusing where mmap.c merges
adjacent vmas: most especially in the name VM_MERGEABLE_FLAGS, used by
is_mergeable_vma() to let vmas be merged despite flags being different.

Call it VMA_MERGE_DESPITE_FLAGS?  Perhaps, but at present it consists
only of VM_CAN_NONLINEAR: so for now it's clearer on all sides to use
that directly, with a comment on it in is_mergeable_vma().

reference to mmu_gather or tlb.h, and mmap.c doesn't need ksm.h.

Subject: ksm: unmerge is an origin of OOMs

Just as the swapoff system call allocates many pages of RAM to various
processes, perhaps triggering OOM, so "echo 2 >/sys/kernel/mm/ksm/run"
(unmerge) is liable to allocate many pages of RAM to various processes,
perhaps triggering OOM; and each is normally run from a modest admin
process (swapoff or shell), easily repeated until it succeeds.

So treat unmerge_and_remove_all_rmap_items() in the same way that we treat
try_to_unuse(): generalize PF_SWAPOFF to PF_OOM_ORIGIN, and bracket both
with that, to ask the OOM killer to kill them first, to prevent them from
spawning more and more OOM kills.

mremap move's use of ksm_madvise() was assuming -ENOMEM on failure,
because ksm_madvise used to say -EAGAIN for that; but ksm_madvise now says
-ENOMEM (letting madvise convert that to -EAGAIN), and can also say
-ERESTARTSYS when signalled: so pass the error from ksm_madvise.

Subject: pagemap clear_refs: modify to specify anon or mapped vma clearing

The patch makes the clear_refs more versatile in adding the option to
select anonymous pages or file backed pages for clearing.  This addition
has a measurable impact on user space application performance as it
decreases the number of pagewalks in scenarios where one is only
interested in a specific type of page (anonymous or file mapped).

The patch adds anonymous and file backed filters to the clear_refs interface.

echo 1 > /proc/PID/clear_refs resets the bits on all pages
echo 2 > /proc/PID/clear_refs resets the bits on anonymous pages only
echo 3 > /proc/PID/clear_refs resets the bits on file backed pages only

Subject: page-allocator: change migratetype for all pageblocks within a
 high-order page during __rmqueue_fallback

When there are no pages of a target migratetype free, the page allocator
selects a high-order block of another migratetype to allocate from.  When
the order of the page taken is greater than pageblock_order, all
pageblocks within that high-order page should change migratetype so that
pages are later freed to the correct free-lists.

The current behaviour is that pageblocks change migratetype if the order
being split matches the pageblock_order.  When pageblock_order <
MAX_ORDER-1, ownership is not changing correct and pages are being later
freed to the incorrect list and this impacts fragmentation avoidance.

This patch changes all pageblocks within the high-order page being split
to the correct migratetype.  Without the patch, allocation success rates
for hugepages under stress were about 59% of physical memory on x86-64.
With the patch applied, this goes up to 65%.

Subject: kcore: fix vread/vwrite to be aware of holes

vread/vwrite access vmalloc area without checking there is a page or not.
In most case, this works well.

In old ages, the caller of get_vm_ara() is only IOREMAP and there is no
memory hole within vm_struct's [addr...addr + size - PAGE_SIZE] (
-PAGE_SIZE is for a guard page.)

After per-cpu-alloc patch, it uses get_vm_area() for reserve continuous
virtual address but remap _later_.  There tend to be a hole in valid
vmalloc area in vm_struct lists.  Then, skip the hole (not mapped page) is
necessary.  This patch updates vread/vwrite() for avoiding memory hole.

Routines which access vmalloc area without knowing for which addr is used
are
  - /proc/kcore
  - /dev/kmem

kcore checks IOREMAP, /dev/kmem doesn't.  After this patch, IOREMAP is
checked and /dev/kmem will avoid to read/write it.  Fixes to /proc/kcore
will be in the next patch in series.

Subject: kcore: /proc/kcore should use vread

/proc/kcore has its own routine to access vmallc area.  It can be replaced
with vread().  And by this, /proc/kcore can do safe access to vmalloc
area.

Subject: arches: drop superfluous casts in nr_free_pages() callers

Commit 96177299416dbccb73b54e6b344260154a445375 ("Drop free_pages()")
modified nr_free_pages() to return 'unsigned long' instead of 'unsigned
int'.  This made the casts to 'unsigned long' in most callers superfluous,
so remove them.

Subject: tracing, page-allocator: add trace events for page allocation and
 page freeing

This patch adds trace events for the allocation and freeing of pages,
including the freeing of pagevecs.  Using the events, it will be known
what struct page and pfns are being allocated and freed and what the call
site was in many cases.

The page alloc tracepoints be used as an indicator as to whether the
workload was heavily dependant on the page allocator or not.  You can make
a guess based on vmstat but you can't get a per-process breakdown.
Depending on the call path, the call_site for page allocation may be
__get_free_pages() instead of a useful callsite.  Instead of passing down
a return address similar to slab debugging, the user should enable the
stacktrace and seg-addr options to get a proper stack trace.

The pagevec free tracepoint has a different usecase.  It can be used to
get a idea of how many pages are being dumped off the LRU and whether it
is kswapd doing the work or a process doing direct reclaim.

Subject: tracing, page-allocator: add trace events for anti-fragmentation
 falling back to other migratetypes

Fragmentation avoidance depends on being able to use free pages from lists
of the appropriate migrate type.  In the event this is not possible,
__rmqueue_fallback() selects a different list and in some circumstances
change the migratetype of the pageblock.  Simplistically, the more times
this event occurs, the more likely that fragmentation will be a problem
later for hugepage allocation at least but there are other considerations
such as the order of page being split to satisfy the allocation.

This patch adds a trace event for __rmqueue_fallback() that reports what
page is being used for the fallback, the orders of relevant pages, the
desired migratetype and the migratetype of the lists being used, whether
the pageblock changed type and whether this event is important with
respect to fragmentation avoidance or not.  This information can be used
to help analyse fragmentation avoidance and help decide whether
min_free_kbytes should be increased or not.

Subject: tracing, page-allocator: add trace event for page traffic related to
 the buddy lists

The page allocation trace event reports that a page was successfully
allocated but it does not specify where it came from.  When analysing
performance, it can be important to distinguish between pages coming from
the per-cpu allocator and pages coming from the buddy lists as the latter
requires the zone lock to the taken and more data structures to be
examined.

This patch adds a trace event for __rmqueue reporting when a page is being
allocated from the buddy lists.  It distinguishes between being called to
refill the per-cpu lists or whether it is a high-order allocation.
Similarly, this patch adds an event to catch when the PCP lists are being
drained a little and pages are going back to the buddy lists.

This is trickier to draw conclusions from but high activity on those
events could explain why there were a large number of cache misses on a
page-allocator-intensive workload.  The coalescing and splitting of
buddies involves a lot of writing of page metadata and cache line bounces
not to mention the acquisition of an interrupt-safe lock necessary to
enter this path.

Subject: tracing, page-allocator: add a postprocessing script for
 page-allocator-related ftrace events

This patch adds a simple post-processing script for the
page-allocator-related trace events.  It can be used to give an indication
of who the most allocator-intensive processes are and how often the zone
lock was taken during the tracing period.  Example output looks like

Process                   Pages      Pages      Pages    Pages       PCPU     PCPU     PCPU   Fragment Fragment  MigType Fragment Fragment  Unknown

Optionally, the output can include information on the parent or aggregate
based on process name instead of aggregating based on each pid. Example output
including parent information and stripped out the PID looks something like;

Process                        Pages      Pages      Pages    Pages       PCPU     PCPU     PCPU   Fragment Fragment  MigType Fragment Fragment  Unknown

This says that Xorg allocated 3796 pages and it's parent process is gdm
with a PID of 3756;

The postprocessor parses the text output of tracing.  While there is a
binary format, the expectation is that the binary output can be readily
translated into text and post-processed offline.  Obviously if the text
format changes, the parser will break but the regular expression parser is
fairly rudimentary so should be readily adjustable.

Subject: tracing, documentation: add a document describing how to do some
 performance analysis with tracepoints

The documentation for ftrace, events and tracepoints is pretty extensive.
Similarly, the perf PCL tools help files --help are there and the code
simple enough to figure out what much of the switches mean.  However,
pulling the discrete bits and pieces together and translating that into
"how do I solve a problem" requires a fair amount of imagination.

This patch adds a simple document intended to get someone started on the

+		Notes on Analysing Behaviour Using Events and Tracepoints
+
+			Documentation written by Mel Gorman
+		PCL information heavily based on email from Ingo Molnar
+
+1. Introduction
+===============
+
+Tracepoints (see Documentation/trace/tracepoints.txt) can be used without
+creating custom kernel modules to register probe functions using the event
+tracing infrastructure.
+
+Simplistically, tracepoints will represent an important event that when can
+be taken in conjunction with other tracepoints to build a "Big Picture" of
+what is going on within the system. There are a large number of methods for
+gathering and interpreting these events. Lacking any current Best Practises,
+this document describes some of the methods that can be used.
+
+This document assumes that debugfs is mounted on /sys/kernel/debug and that
+the appropriate tracing options have been configured into the kernel. It is
+assumed that the PCL tool tools/perf has been installed and is in your path.
+
+2. Listing Available Events
+===========================
+
+2.1 Standard Utilities
+----------------------
+
+All possible events are visible from /sys/kernel/debug/tracing/events. Simply
+calling
+
+  $ find /sys/kernel/debug/tracing/events -type d
+
+will give a fair indication of the number of events available.
+
+2.2 PCL
+-------
+
+Discovery and enumeration of all counters and events, including tracepoints
+are available with the perf tool. Getting a list of available events is a
+simple case of
+
+  $ perf list 2>&1 | grep Tracepoint
+  ext4:ext4_free_inode                     [Tracepoint event]
+  ext4:ext4_request_inode                  [Tracepoint event]
+  ext4:ext4_allocate_inode                 [Tracepoint event]
+  ext4:ext4_write_begin                    [Tracepoint event]
+  ext4:ext4_ordered_write_end              [Tracepoint event]
+  [ .... remaining output snipped .... ]
+
+
+2. Enabling Events
+==================
+
+2.1 System-Wide Event Enabling
+------------------------------
+
+See Documentation/trace/events.txt for a proper description on how events
+can be enabled system-wide. A short example of enabling all events related
+to page allocation would look something like
+
+  $ for i in `find /sys/kernel/debug/tracing/events -name "enable" | grep mm_`; do echo 1 > $i; done
+
+2.2 System-Wide Event Enabling with SystemTap
+---------------------------------------------
+
+In SystemTap, tracepoints are accessible using the kernel.trace() function
+call. The following is an example that reports every 5 seconds what processes
+were allocating the pages.
+
+  global page_allocs
+
+  probe kernel.trace("mm_page_alloc") {
+  	page_allocs[execname()]++
+  }
+
+  function print_count() {
+  	printf ("%-25s %-s\n", "#Pages Allocated", "Process Name")
+  	foreach (proc in page_allocs-)
+  		printf("%-25d %s\n", page_allocs[proc], proc)
+  	printf ("\n")
+  	delete page_allocs
+  }
+
+  probe timer.s(5) {
+          print_count()
+  }
+
+2.3 System-Wide Event Enabling with PCL
+---------------------------------------
+
+By specifying the -a switch and analysing sleep, the system-wide events
+for a duration of time can be examined.
+
+ $ perf stat -a \
+	-e kmem:mm_page_alloc -e kmem:mm_page_free_direct \
+	-e kmem:mm_pagevec_free \
+	sleep 10
+ Performance counter stats for 'sleep 10':
+
+           9630  kmem:mm_page_alloc
+           2143  kmem:mm_page_free_direct
+           7424  kmem:mm_pagevec_free
+
+   10.002577764  seconds time elapsed
+
+Similarly, one could execute a shell and exit it as desired to get a report
+at that point.
+
+2.4 Local Event Enabling
+------------------------
+
+Documentation/trace/ftrace.txt describes how to enable events on a per-thread
+basis using set_ftrace_pid.
+
+2.5 Local Event Enablement with PCL
+-----------------------------------
+
+Events can be activate and tracked for the duration of a process on a local
+basis using PCL such as follows.
+
+  $ perf stat -e kmem:mm_page_alloc -e kmem:mm_page_free_direct \
+		 -e kmem:mm_pagevec_free ./hackbench 10
+  Time: 0.909
+
+    Performance counter stats for './hackbench 10':
+
+          17803  kmem:mm_page_alloc
+          12398  kmem:mm_page_free_direct
+           4827  kmem:mm_pagevec_free
+
+    0.973913387  seconds time elapsed
+
+3. Event Filtering
+==================
+
+Documentation/trace/ftrace.txt covers in-depth how to filter events in
+ftrace.  Obviously using grep and awk of trace_pipe is an option as well
+as any script reading trace_pipe.
+
+4. Analysing Event Variances with PCL
+=====================================
+
+Any workload can exhibit variances between runs and it can be important
+to know what the standard deviation in. By and large, this is left to the
+performance analyst to do it by hand. In the event that the discrete event
+occurrences are useful to the performance analyst, then perf can be used.
+
+  $ perf stat --repeat 5 -e kmem:mm_page_alloc -e kmem:mm_page_free_direct
+			-e kmem:mm_pagevec_free ./hackbench 10
+  Time: 0.890
+  Time: 0.895
+  Time: 0.915
+  Time: 1.001
+  Time: 0.899
+
+   Performance counter stats for './hackbench 10' (5 runs):
+
+          16630  kmem:mm_page_alloc         ( +-   3.542% )
+          11486  kmem:mm_page_free_direct   ( +-   4.771% )
+           4730  kmem:mm_pagevec_free       ( +-   2.325% )
+
+    0.982653002  seconds time elapsed   ( +-   1.448% )
+
+In the event that some higher-level event is required that depends on some
+aggregation of discrete events, then a script would need to be developed.
+
+Using --repeat, it is also possible to view how events are fluctuating over
+time on a system wide basis using -a and sleep.
+
+  $ perf stat -e kmem:mm_page_alloc -e kmem:mm_page_free_direct \
+		-e kmem:mm_pagevec_free \
+		-a --repeat 10 \
+		sleep 1
+  Performance counter stats for 'sleep 1' (10 runs):
+
+           1066  kmem:mm_page_alloc         ( +-  26.148% )
+            182  kmem:mm_page_free_direct   ( +-   5.464% )
+            890  kmem:mm_pagevec_free       ( +-  30.079% )
+
+    1.002251757  seconds time elapsed   ( +-   0.005% )
+
+5. Higher-Level Analysis with Helper Scripts
+============================================
+
+When events are enabled the events that are triggering can be read from
+/sys/kernel/debug/tracing/trace_pipe in human-readable format although binary
+options exist as well. By post-processing the output, further information can
+be gathered on-line as appropriate. Examples of post-processing might include
+
+  o Reading information from /proc for the PID that triggered the event
+  o Deriving a higher-level event from a series of lower-level events.
+  o Calculate latencies between two events
+
+Documentation/trace/postprocess/trace-pagealloc-postprocess.pl is an example
+script that can read trace_pipe from STDIN or a copy of a trace. When used
+on-line, it can be interrupted once to generate a report without existing
+and twice to exit.
+
+Simplistically, the script just reads STDIN and counts up events but it
+also can do more such as
+
+  o Derive high-level events from many low-level events. If a number of pages
+    are freed to the main allocator from the per-CPU lists, it recognises
+    that as one per-CPU drain even though there is no specific tracepoint
+    for that event
+  o It can aggregate based on PID or individual process number
+  o In the event memory is getting externally fragmented, it reports
+    on whether the fragmentation event was severe or moderate.
+  o When receiving an event about a PID, it can record who the parent was so
+    that if large numbers of events are coming from very short-lived
+    processes, the parent process responsible for creating all the helpers
+    can be identified
+
+6. Lower-Level Analysis with PCL
+================================
+
+There may also be a requirement to identify what functions with a program
+were generating events within the kernel. To begin this sort of analysis, the
+data must be recorded. At the time of writing, this required root
+
+  $ perf record -c 1 \
+	-e kmem:mm_page_alloc -e kmem:mm_page_free_direct \
+	-e kmem:mm_pagevec_free \
+	./hackbench 10
+  Time: 0.894
+  [ perf record: Captured and wrote 0.733 MB perf.data (~32010 samples) ]
+
+Note the use of '-c 1' to set the event period to sample. The default sample
+period is quite high to minimise overhead but the information collected can be
+very coarse as a result.
+
+This record outputted a file called perf.data which can be analysed using
+perf report.
+
+  $ perf report
+  # Samples: 30922
+  #
+  # Overhead    Command                     Shared Object
+  # ........  .........  ................................
+  #
+      87.27%  hackbench  [vdso]
+       6.85%  hackbench  /lib/i686/cmov/libc-2.9.so
+       2.62%  hackbench  /lib/ld-2.9.so
+       1.52%       perf  [vdso]
+       1.22%  hackbench  ./hackbench
+       0.48%  hackbench  [kernel]
+       0.02%       perf  /lib/i686/cmov/libc-2.9.so

+       0.01%       perf  /lib/ld-2.9.so

+  #
+  # (For more details, try: perf report --sort comm,dso,symbol)
+  #
+
+According to this, the vast majority of events occured triggered on events
+within the VDSO. With simple binaries, this will often be the case so lets
+take a slightly different example. In the course of writing this, it was
+noticed that X was generating an insane amount of page allocations so lets look
+at it
+
+  $ perf record -c 1 -f \
+		-e kmem:mm_page_alloc -e kmem:mm_page_free_direct \
+		-e kmem:mm_pagevec_free \
+		-p `pidof X`
+
+This was interrupted after a few seconds and
+
+  $ perf report
+  # Samples: 27666
+  #
+  # Overhead  Command                            Shared Object

+			Subsystem Trace Points: kmem
+
+The tracing system kmem captures events related to object and page allocation
+within the kernel. Broadly speaking there are four major subheadings.
+
+  o Slab allocation of small objects of unknown type (kmalloc)
+  o Slab allocation of small objects of known type
+  o Page allocation
+  o Per-CPU Allocator Activity
+  o External Fragmentation
+
+This document will describe what each of the tracepoints are and why they
+might be useful.
+
+1. Slab allocation of small objects of unknown type
+===================================================
+kmalloc		call_site=%lx ptr=%p bytes_req=%zu bytes_alloc=%zu gfp_flags=%s
+kmalloc_node	call_site=%lx ptr=%p bytes_req=%zu bytes_alloc=%zu gfp_flags=%s node=%d
+kfree		call_site=%lx ptr=%p
+
+Heavy activity for these events may indicate that a specific cache is
+justified, particularly if kmalloc slab pages are getting significantly
+internal fragmented as a result of the allocation pattern. By correlating
+kmalloc with kfree, it may be possible to identify memory leaks and where
+the allocation sites were.
+
+
+2. Slab allocation of small objects of known type
+=================================================
+kmem_cache_alloc	call_site=%lx ptr=%p bytes_req=%zu bytes_alloc=%zu gfp_flags=%s
+kmem_cache_alloc_node	call_site=%lx ptr=%p bytes_req=%zu bytes_alloc=%zu gfp_flags=%s node=%d
+kmem_cache_free		call_site=%lx ptr=%p
+
+These events are similar in usage to the kmalloc-related events except that
+it is likely easier to pin the event down to a specific cache. At the time
+of writing, no information is available on what slab is being allocated from,
+but the call_site can usually be used to extrapolate that information
+
+3. Page allocation
+==================
+mm_page_alloc		  page=%p pfn=%lu order=%d migratetype=%d gfp_flags=%s
+mm_page_alloc_zone_locked page=%p pfn=%lu order=%u migratetype=%d cpu=%d percpu_refill=%d
+mm_page_free_direct	  page=%p pfn=%lu order=%d
+mm_pagevec_free		  page=%p pfn=%lu order=%d cold=%d
+
+These four events deal with page allocation and freeing. mm_page_alloc is
+a simple indicator of page allocator activity. Pages may be allocated from
+the per-CPU allocator (high performance) or the buddy allocator.
+
+If pages are allocated directly from the buddy allocator, the
+mm_page_alloc_zone_locked event is triggered. This event is important as high
+amounts of activity imply high activity on the zone->lock. Taking this lock
+impairs performance by disabling interrupts, dirtying cache lines between
+CPUs and serialising many CPUs.
+
+When a page is freed directly by the caller, the mm_page_free_direct event
+is triggered. Significant amounts of activity here could indicate that the
+callers should be batching their activities.
+
+When pages are freed using a pagevec, the mm_pagevec_free is
+triggered. Broadly speaking, pages are taken off the LRU lock in bulk and
+freed in batch with a pagevec. Significant amounts of activity here could
+indicate that the system is under memory pressure and can also indicate
+contention on the zone->lru_lock.
+
+4. Per-CPU Allocator Activity
+=============================
+mm_page_alloc_zone_locked	page=%p pfn=%lu order=%u migratetype=%d cpu=%d percpu_refill=%d
+mm_page_pcpu_drain		page=%p pfn=%lu order=%d cpu=%d migratetype=%d
+
+In front of the page allocator is a per-cpu page allocator. It exists only
+for order-0 pages, reduces contention on the zone->lock and reduces the
+amount of writing on struct page.
+
+When a per-CPU list is empty or pages of the wrong type are allocated,
+the zone->lock will be taken once and the per-CPU list refilled. The event
+triggered is mm_page_alloc_zone_locked for each page allocated with the
+event indicating whether it is for a percpu_refill or not.
+
+When the per-CPU list is too full, a number of pages are freed, each one
+which triggers a mm_page_pcpu_drain event.
+
+The individual nature of the events are so that pages can be tracked
+between allocation and freeing. A number of drain or refill pages that occur
+consecutively imply the zone->lock being taken once. Large amounts of PCP
+refills and drains could imply an imbalance between CPUs where too much work
+is being concentrated in one place. It could also indicate that the per-CPU
+lists should be a larger size. Finally, large amounts of refills on one CPU
+and drains on another could be a factor in causing large amounts of cache
+line bounces due to writes between CPUs and worth investigating if pages
+can be allocated and freed on the same CPU through some algorithm change.
+
+5. External Fragmentation
+=========================
+mm_page_alloc_extfrag		page=%p pfn=%lu alloc_order=%d fallback_order=%d pageblock_order=%d alloc_migratetype=%d fallback_migratetype=%d fragmenting=%d change_ownership=%d
+
+External fragmentation affects whether a high-order allocation will be
+successful or not. For some types of hardware, this is important although
+it is avoided where possible. If the system is using huge pages and needs
+to be able to resize the pool over the lifetime of the system, this value
+is important.
+
+Large numbers of this event implies that memory is fragmenting and
+high-order allocations will start failing at some time in the future. One
+means of reducing the occurange of this event is to increase the size of
+min_free_kbytes in increments of 3*pageblock_size*nr_online_nodes where
+pageblock_size is usually the size of the default hugepage size.

Subject: mm: add_to_swap_cache() must not sleep

After commit 355cfa73 ("mm: modify swap_map and add SWAP_HAS_CACHE flag"),
read_swap_cache_async() will busy-wait while a entry doesn't exist in swap
cache but it has SWAP_HAS_CACHE flag.

Such entries can exist on add/delete path of swap cache.  On add path,
add_to_swap_cache() is called soon after SWAP_HAS_CACHE flag is set, and
on delete path, swapcache_free() will be called (SWAP_HAS_CACHE flag is
cleared) soon after __delete_from_swap_cache() is called.  So, the
busy-wait works well in most cases.

But this mechanism can cause soft lockup if add_to_swap_cache() sleeps and
read_swap_cache_async() tries to swap-in the same entry on the same cpu.

This patch calls radix_tree_preload() before swapcache_prepare() and
divides add_to_swap_cache() into two part: radix_tree_preload() part and
radix_tree_insert() part(define it as __add_to_swap_cache()).

Subject: mm: add_to_swap_cache() does not return -EEXIST

After commit 355cfa73 ("mm: modify swap_map and add SWAP_HAS_CACHE flag"),
only the context which have set SWAP_HAS_CACHE flag by swapcache_prepare()
or get_swap_page() would call add_to_swap_cache().  So add_to_swap_cache()
doesn't return -EEXIST any more.

Even though it doesn't return -EEXIST, it's not good behavior conceptually
to call swapcache_prepare() in the -EEXIST case, because it means clearing
SWAP_HAS_CACHE flag while the entry is on swap cache.

This patch removes redundant codes and comments from callers of it, and
adds VM_BUG_ON() in error path of add_to_swap_cache() and some comments.

Subject: mm: remove broken 'kzalloc' mempool

The kzalloc mempool zeros items when they are initially allocated, but
does not rezero used items that are returned to the pool.  Consequently
mempool_alloc()s may return non-zeroed memory.

Since there are/were only two in-tree users for
mempool_create_kzalloc_pool(), and 'fixing' this in a way that will
re-zero used (but not new) items before first use is non-trivial, just
remove it.

Subject: mm: introduce page_lru_base_type()

Instead of abusing page_is_file_cache() for LRU list index arithmetic, add
another helper with a more appropriate name and convert the non-boolean
users of page_is_file_cache() accordingly.

This new helper gives the LRU base type a page is supposed to live on,
inactive anon or inactive file.

Subject: mm: return boolean from page_is_file_cache()

page_is_file_cache() has been used for both boolean checks and LRU
arithmetic, which was always a bit weird.

Now that page_lru_base_type() exists for LRU arithmetic, make
page_is_file_cache() a real predicate function and adjust the
boolean-using callsites to drop those pesky double negations.

Subject: page-allocator: limit the number of MIGRATE_RESERVE pageblocks per
 zone

After anti-fragmentation was merged, a bug was reported whereby devices
that depended on high-order atomic allocations were failing.  The solution
was to preserve a property in the buddy allocator which tended to keep the
minimum number of free pages in the zone at the lower physical addresses
and contiguous.  To preserve this property, MIGRATE_RESERVE was introduced
and a number of pageblocks at the start of a zone would be marked
"reserve", the number of which depended on min_free_kbytes.

Anti-fragmentation works by avoiding the mixing of page migratetypes
within the same pageblock.  One way of helping this is to increase
min_free_kbytes because it becomes less like that it will be necessary to
place pages of of MIGRATE_RESERVE is unbounded, the free memory is kept
there in large contiguous blocks instead of helping anti-fragmentation as
much as it should.  With the page-allocator tracepoint patches applied, it
was found during anti-fragmentation tests that the number of
fragmentation-related events were far higher than expected even with
min_free_kbytes at higher values.

This patch limits the number of MIGRATE_RESERVE blocks that exist per zone
to two.  For example, with a sufficient min_free_kbytes, 4MB of memory
will be kept aside on an x86-64 and remain more or less free and
contiguous for the systems uptime.  This should be sufficient for devices
depending on high-order atomic allocations while helping fragmentation
control when min_free_kbytes is tuned appropriately.  As side-effect of
this patch is that the reserve variable is converted to int as unsigned
long was the wrong type to use when ensuring that only the required number
of reserve blocks are created.

With the patches applied, fragmentation-related events as measured by the
page allocator tracepoints were significantly reduced when running some
fragmentation stress-tests on systems with min_free_kbytes tuned to a
value appropriate for hugepage allocations at runtime.  On x86, the events
recorded were reduced by 99.8%, on x86-64 by 99.72% and on ppc64 by
99.83%.

Subject: memory hotplug: fix updating of num_physpages for hot plugged memory

Sizing of memory allocations shouldn't depend on the number of physical
pages found in a system, as that generally includes (perhaps a huge amount
of) non-RAM pages.  The amount of what actually is usable as storage
should instead be used as a basis here.

In line with that, the memory hotplug code should update num_physpages in
a way that it retains its original (post-boot) meaning; in particular,
decreasing the value should at best be done with great care - this patch
doesn't try to ever decrease this value at all as it doesn't really seem
meaningful to do so.

From 4481374ce88ba8f460c8b89f2572027bd27057d0 Mon Sep 17 00:00:00 2001
From: Jan Beulich <JBeulich@novell.com>
Date: Mon, 21 Sep 2009 17:03:05 -0700
Subject: mm: replace various uses of num_physpages by totalram_pages

Sizing of memory allocations shouldn't depend on the number of physical
pages found in a system, as that generally includes (perhaps a huge amount
of) non-RAM pages.  The amount of what actually is usable as storage
should instead be used as a basis here.

Some of the calculations (i.e.  those not intending to use high memory)
should likely even use (totalram_pages - totalhigh_pages).

From 3c1596efe167322dae87f8390d36f91ce2d7f936 Mon Sep 17 00:00:00 2001
From: Jan Beulich <JBeulich@novell.com>
Date: Mon, 21 Sep 2009 17:03:06 -0700
Subject: mm: don't use alloc_bootmem_low() where not strictly needed

Since alloc_bootmem() will never return inaccessible (via virtual
addressing) memory anyway, using the ..._low() variant only makes sense
when the physical address range of the allocated memory must fulfill
further constraints, espacially since on 64-bits (or more generally in all
cases where the pools the two variants allocate from are than the full
available range.

Probably the use in alloc_tce_table() could also be eliminated (based on
code inspection of pci-calgary_64.c), but that seems too risky given I
know nothing about that hardware and have no way to test it.

Subject: mm: also use alloc_large_system_hash() for the PID hash table

This is being done by allowing boot time allocations to specify that they
may want a sub-page sized amount of memory.

Overall this seems more consistent with the other hash table allocations,
and allows making two supposedly mm-only variables really mm-only
(nr_{kernel,all}_pages).

Subject: mm: do batched scans for mem_cgroup

For mem_cgroup, shrink_zone() may call shrink_list() with nr_to_scan=1, in
which case shrink_list() _still_ calls isolate_pages() with the much
larger SWAP_CLUSTER_MAX.  It effectively scales up the inactive list scan
rate by up to 32 times.

For example, with 16k inactive pages and DEF_PRIORITY=12, (16k >> 12)=4.
So when shrink_zone() expects to scan 4 pages in the active/inactive list,
the active list will be scanned 4 pages, while the inactive list will be
(over) scanned SWAP_CLUSTER_MAX=32 pages in effect.  And that could break
the balance between the two lists.

It can further impact the scan of anon active list, due to the anon
active/inactive ratio rebalance logic in balance_pgdat()/shrink_zone():

inactive anon list over scanned => inactive_anon_is_low() == TRUE
                                => shrink_active_list()
                                => active anon list over scanned

So the end result may be

- anon inactive  => over scanned
- anon active    => over scanned (maybe not as much)
- file inactive  => over scanned
- file active    => under scanned (relatively)

The accesses to nr_saved_scan are not lock protected and so not 100%
accurate, however we can tolerate small errors and the resulted small
imbalanced scan rates between zones.

fat memory and each thread have following oom_adj and oom_score.

     thread-A: oom_adj = OOM_DISABLE, oom_score = 0
     thread-B: oom_adj = 0,           oom_score = very-high

Then, select_bad_process() select thread-B, but oom_kill_task() refuse
kill the task because thread-A have OOM_DISABLE.  Thus __out_of_memory()
call select_bad_process() again.  but select_bad_process() select the same
task.  It mean kernel fall in livelock.

The fact is, select_bad_process() must select killable task.  otherwise
OOM logic go into livelock.

And root cause is, oom_adj shouldn't be per-thread value.  it should be
per-process value because OOM-killer kill a process, not thread.  Thus
This patch moves oomkilladj (now more appropriately named oom_adj) from
struct task_struct to struct signal_struct.  it naturally prevent
select_bad_process() choose wrong task.

Subject: oom: oom_kill doesn't kill vfork parent (or child)

Current oom_kill doesn't only kill the victim process, but also kill all
thas shread the same mm.  it mean vfork parent will be killed.

This is definitely incorrect.  another process have another oom_adj.  we
shouldn't ignore their oom_adj (it might have OOM_DISABLE).

following caller hit the minefield.

===============================
        switch (constraint) {
        case CONSTRAINT_MEMORY_POLICY:
                oom_kill_process(current, gfp_mask, order, 0, NULL,
                                "No available memory (MPOL_BIND)");
                break;

Note: force_sig(SIGKILL) send SIGKILL to all thread in the process.
We don't need to care multi thread in here.

Subject: page-allocator: split per-cpu list into one-list-per-migrate-type

The following two patches remove searching in the page allocator fast-path
by maintaining multiple free-lists in the per-cpu structure.  At the time
the search was introduced, increasing the per-cpu structures would waste a
lot of memory as per-cpu structures were statically allocated at
compile-time.  This is no longer the case.

The patches are as follows. They are based on mmotm-2009-08-27.

Patch 1 adds multiple lists to struct per_cpu_pages, one per
	migratetype that can be stored on the PCP lists.

Patch 2 notes that the pcpu drain path check empty lists multiple times. The
	patch reduces the number of checks by maintaining a count of free
	lists encountered. Lists containing pages will then free multiple
	pages in batch

The patches were tested with kernbench, netperf udp/tcp, hackbench and
sysbench.  The netperf tests were not bound to any CPU in particular and
were run such that the results should be 99% confidence that the reported
results are within 1% of the estimated mean.  sysbench was run with a
postgres background and read-only tests.  Similar to netperf, it was run
multiple times so that it's 99% confidence results are within 1%.  The
patches were tested on x86, x86-64 and ppc64 as

x86:	Intel Pentium D 3GHz with 8G RAM (no-brand machine)
	kernbench	- No significant difference, variance well within noise
	netperf-udp	- 1.34% to 2.28% gain
	netperf-tcp	- 0.45% to 1.22% gain
	hackbench	- Small variances, very close to noise
	sysbench	- Very small gains

x86-64:	AMD Phenom 9950 1.3GHz with 8G RAM (no-brand machine)
	kernbench	- No significant difference, variance well within noise
	netperf-udp	- 1.83% to 10.42% gains
	netperf-tcp	- No conclusive until buffer >= PAGE_SIZE
				4096	+15.83%
				8192	+ 0.34% (not significant)
				16384	+ 1%
	hackbench	- Small gains, very close to noise
	sysbench	- 0.79% to 1.6% gain

ppc64:	PPC970MP 2.5GHz with 10GB RAM (it's a terrasoft powerstation)
	kernbench	- No significant difference, variance well within noise
	netperf-udp	- 2-3% gain for almost all buffer sizes tested
	netperf-tcp	- losses on small buffers, gains on larger buffers
			  possibly indicates some bad caching effect.
	hackbench	- No significant difference
	sysbench	- 2-4% gain

This patch:

Currently the per-cpu page allocator searches the PCP list for pages of
the correct migrate-type to reduce the possibility of pages being
inappropriate placed from a fragmentation perspective.  This search is
potentially expensive in a fast-path and undesirable.  Splitting the
per-cpu list into multiple lists increases the size of a per-cpu structure
and this was potentially a major problem at the time the search was
introduced.  These problem has been mitigated as now only the necessary
number of structures is allocated for the running system.

This patch replaces a list search in the per-cpu allocator with one list
per migrate type.  The potential snag with this approach is when bulk
freeing pages.  We round-robin free pages based on migrate type which has
little bearing on the cache hotness of the page and potentially checks
empty lists repeatedly in the event the majority of PCP pages are of one
type.

Subject: page-allocator: maintain rolling count of pages to free from the PCP

When round-robin freeing pages from the PCP lists, empty lists may be
encountered.  In the event one of the lists has more pages than another,
there may be numerous checks for list_empty() which is undesirable.  This
patch maintains a count of pages to free which is incremented when empty
lists are encountered.  The intention is that more pages will then be
freed from fuller lists than the empty ones reducing the number of empty
list checks in the free path.

Subject: mm: fix NUMA accounting in numastat.txt

In Documentation/numastat.txt, it confused me.  For example, there are
nodes [0,1] in system.

barrios:~$ cat /proc/zoneinfo | egrep 'numa|zone'
Node 0, zone	DMA
	numa_hit	33226
	numa_miss	1739
	numa_foreign	27978
	..
	..
Node 1, zone	DMA
	numa_hit	307
	numa_miss	46900
	numa_foreign	0

1) In node 0,  NUMA_MISS means it wanted to allocate page
in node 1 but ended up with page in node 0

2) In node 0, NUMA_FOREIGN means it wanted to allocate page
in node 0 but ended up with page from Node 1.

But now, numastat explains it oppositely about (MISS, FOREIGN).
Let's fix up with viewpoint of zone.

Subject: mm: munlock use follow_page

Hiroaki Wakabayashi points out that when mlock() has been interrupted
by SIGKILL, the subsequent munlock() takes unnecessarily long because
its use of __get_user_pages() insists on faulting in all the pages
which mlock() never reached.

It's worse than slowness if mlock() is terminated by Out Of Memory kill:
the munlock_vma_pages_all() in exit_mmap() insists on faulting in all the
pages which mlock() could not find memory for; so innocent bystanders are
killed too, and perhaps the system hangs.

__get_user_pages() does a lot that's silly for munlock(): so remove the
munlock option from __mlock_vma_pages_range(), and use a simple loop of
follow_page()s in munlock_vma_pages_range() instead; ignoring absent
pages, and not marking present pages as accessed or dirty.

(Change munlock() to only go so far as mlock() reached?  That does not
work out, given the convention that mlock() claims complete success even
when it has to give up early - in part so that an underlying file can be
extended later, and those pages locked which earlier would give SIGBUS.)

GUP_FLAGS_IGNORE_VMA_PERMISSIONS and GUP_FLAGS_IGNORE_SIGKILL were
flags added solely to prevent __get_user_pages() from doing some of
what it usually does, in the munlock case: we can now remove them.

Subject: mm: add get_dump_page

In preparation for the next patch, add a simple get_dump_page(addr)
interface for the CONFIG_ELF_CORE dumpers to use, instead of calling
get_user_pages() directly.  They're not interested in errors: they
just want to use holes as much as possible, to save space and make
sure that the data is aligned where the headers said it would be.

Oh, and don't use that horrid DUMP_SEEK(off) macro!

Subject: mm: FOLL_DUMP replace FOLL_ANON

The "FOLL_ANON optimization" and its use_zero_page() test have caused
confusion and bugs: why does it test VM_SHARED? for the very good but
unsatisfying reason that VMware crashed without.  As we look to maybe
reinstating anonymous use of the ZERO_PAGE, we need to sort this out.

Easily done: it's silly for __get_user_pages() and follow_page() to
be guessing whether it's safe to assume that they're being used for
a coredump (which can take a shortcut snapshot where other uses must
handle a fault) - just tell them with GUP_FLAGS_DUMP and FOLL_DUMP.

get_dump_page() doesn't even want a ZERO_PAGE: an error suits fine.

follow_hugetlb_page() shouldn't be guessing about the coredump case
either: pass the foll_flags down to it, instead of just the write bit.

Remove that obscure huge_zeropage_ok() test.  The decision is easy,
though unlike the non-huge case - here vm_ops->fault is always set.
But we know that a fault would serve up zeroes, unless there's
already a hugetlbfs pagecache page to back the range.

(Alternatively, since hugetlb pages aren't swapped out under pressure,
you could save more dump space by arguing that a page not yet faulted
into this process cannot be relevant to the dump; but that would be
more surprising.)

Subject: mm: fix anonymous dirtying

do_anonymous_page() has been wrong to dirty the pte regardless.
If it's not going to mark the pte writable, then it won't help
to mark it dirty here, and clogs up memory with pages which will
need swap instead of being thrown away.  Especially wrong if no
overcommit is chosen, and this vma is not yet VM_ACCOUNTed -
we could exceed the limit and OOM despite no overcommit.

Subject: mm: reinstate ZERO_PAGE

KAMEZAWA Hiroyuki has observed customers of earlier kernels taking
advantage of the ZERO_PAGE: which we stopped do_anonymous_page() from
using in 2.6.24.  And there were a couple of regression reports on LKML.

Following suggestions from Linus, reinstate do_anonymous_page() use of
the ZERO_PAGE; but this time avoid dirtying its struct page cacheline
with (map)count updates - let vm_normal_page() regard it as abnormal.

Use it only on arches which __HAVE_ARCH_PTE_SPECIAL (x86, s390, sh32,
most powerpc): that's not essential, but minimizes additional branches
(keeping them in the unlikely pte_special case); and incidentally
excludes mips (some models of which needed eight colours of ZERO_PAGE
to avoid costly exceptions).

Don't be fanatical about avoiding ZERO_PAGE updates: get_user_pages()
callers won't want to make exceptions for it, so increment its count
there.  Changes to mlock and migration? happily seems not needed.

In most places it's quicker to check pfn than struct page address:
prepare a __read_mostly zero_pfn for that.  Does get_dump_page()
still need its ZERO_PAGE check? probably not, but keep it anyway.

Subject: mm: FOLL flags for GUP flags

__get_user_pages() has been taking its own GUP flags, then processing
them into FOLL flags for follow_page().  Though oddly named, the FOLL
flags are more widely used, so pass them to __get_user_pages() now.
Sorry, VM flags, VM_FAULT flags and FAULT_FLAGs are still distinct.

(The patch to __get_user_pages() looks peculiar, with both gup_flags
and foll_flags: the gup_flags remain constant; but as before there's
an exceptional case, out of scope of the patch, in which foll_flags
per page have FOLL_WRITE masked off.)

Subject: mm: m(un)lock avoid ZERO_PAGE

I'm still reluctant to clutter __get_user_pages() with another flag, just
to avoid touching ZERO_PAGE count in mlock(); though we can add that later
if it shows up as an issue in practice.

But when mlocking, we can test page->mapping slightly earlier, to avoid
the potentially bouncy rescheduling of lock_page on ZERO_PAGE - mlock
didn't lock_page in olden ZERO_PAGE days, so we might have regressed.

And when munlocking, it turns out that FOLL_DUMP coincidentally does
what's needed to avoid all updates to ZERO_PAGE, so use that here also.
Plus add comment suggested by KAMEZAWA Hiroyuki.

Subject: mm: ZERO_PAGE without PTE_SPECIAL

Reinstate anonymous use of ZERO_PAGE to all architectures, not just to
those which __HAVE_ARCH_PTE_SPECIAL: as suggested by Nick Piggin.

Contrary to how I'd imagined it, there's nothing ugly about this, just a
zero_pfn test built into one or another block of vm_normal_page().

But the MIPS ZERO_PAGE-of-many-colours case demands is_zero_pfn() and
my_zero_pfn() inlines.  Reinstate its mremap move_pte() shuffling of
ZERO_PAGEs we did from 2.6.17 to 2.6.19?  Not unless someone shouts for
that: it would have to take vm_flags to weed out some cases.

So there is no need to reset it again, just remove it.

Subject: tmpfs: depend on shmem

CONFIG_SHMEM off gives you (ramfs masquerading as) tmpfs, even when
CONFIG_TMPFS is off: that's a little anomalous, and I'd intended to make
more sense of it by removing CONFIG_TMPFS altogether, always enabling its
code when CONFIG_SHMEM; but so many defconfigs have CONFIG_SHMEM on
CONFIG_TMPFS off that we'd better leave that as is.

But there is no point in asking for CONFIG_TMPFS if CONFIG_SHMEM is off:
make TMPFS depend on SHMEM, which also prevents TMPFS_POSIX_ACL
shmem_acl.o being pointlessly built into the kernel when SHMEM is off.

And a selfish change, to prevent the world from being rebuilt when I
switch between CONFIG_SHMEM on and off: the only CONFIG_SHMEM in the
header files is mm.h shmem_lock() - give that a shmem.c stub instead.

Subject: mmap: avoid unnecessary anon_vma lock acquisition in vma_adjust()

We noticed very erratic behavior [throughput] with the AIM7 shared
workload running on recent distro [SLES11] and mainline kernels on an
8-socket, 32-core, 256GB x86_64 platform.  On the SLES11 kernel
[2.6.27.19+] with Barcelona processors, as we increased the load [10s of
thousands of tasks], the throughput would vary between two "plateaus"--one
at ~65K jobs per minute and one at ~130K jpm.  The simple patch below
causes the results to smooth out at the ~130k plateau.

But wait, there's more:

We do not see this behavior on smaller platforms--e.g., 4 socket/8 core.
This could be the result of the larger number of cpus on the larger
platform--a scalability issue--or it could be the result of the larger
number of interconnect "hops" between some nodes in this platform and how
the tasks for a given load end up distributed over the nodes' cpus and
memories--a stochastic NUMA effect.

The variability in the results are less pronounced [on the same platform]
with Shanghai processors and with mainline kernels.  With 31-rc6 on
Shanghai processors and 288 file systems on 288 fibre attached storage
volumes, the curves [jpm vs load] are both quite flat with the patched
kernel consistently producing ~3.9% better throughput [~80K jpm vs ~77K
jpm] than the unpatched kernel.

Profiling indicated that the "slow" runs were incurring high[er]
contention on an anon_vma lock in vma_adjust(), apparently called from the
sbrk() system call.

The patch:

A comment in mm/mmap.c:vma_adjust() suggests that we don't really need the
anon_vma lock when we're only adjusting the end of a vma, as is the case
for brk().  The comment questions whether it's worth while to optimize for
this case.  Apparently, on the newer, larger x86_64 platforms, with
interesting NUMA topologies, it is worth while--especially considering
that the patch [if correct!] is quite simple.

We can detect this condition--no overlap with next vma--by noting a NULL
"importer".  The anon_vma pointer will also be NULL in this case, so
simply avoid loading vma->anon_vma to avoid the lock.

However, we DO need to take the anon_vma lock when we're inserting a vma
['insert' non-NULL] even when we have no overlap [NULL "importer"], so we
need to check for 'insert', as well.  And Hugh points out that we should
also take it when adjusting vm_start (so that rmap.c can rely upon
vma_address() while it holds the anon_vma lock).

akpm: Zhang Yanmin reprts a 150% throughput improvement with aim7, so it
might be -stable material even though thiss isn't a regression: "this
issue is not clear on dual socket Nehalem machine (2*4*2 cpu), but is
severe on large machine (4*8*2 cpu)"

Subject: mmap: save some cycles for the shared anonymous mapping

shmem_zero_setup() does not change vm_start, pgoff or vm_flags, only some
drivers change them (such as /driver/video/bfin-t350mcqb-fb.c).

Move these codes to a more proper place to save cycles for shared
anonymous mapping.

Subject: hugetlbfs: allow the creation of files suitable for MAP_PRIVATE on
 the vfs internal mount

This patchset adds a flag to mmap that allows the user to request that an
anonymous mapping be backed with huge pages.  This mapping will borrow
functionality from the huge page shm code to create a file on the kernel
internal mount and use it to approximate an anonymous mapping.  The
MAP_HUGETLB flag is a modifier to MAP_ANONYMOUS and will not work without
both flags being preset.

A new flag is necessary because there is no other way to hook into huge
pages without creating a file on a hugetlbfs mount which wouldn't be
MAP_ANONYMOUS.

To userspace, this mapping will behave just like an anonymous mapping
because the file is not accessible outside of the kernel.

This patchset is meant to simplify the programming model.  Presently there
is a large chunk of boiler platecode, contained in libhugetlbfs, required
to create private, hugepage backed mappings.  This patch set would allow
use of hugepages without linking to libhugetlbfs or having hugetblfs
mounted.

Unification of the VM code would provide these same benefits, but it has
been resisted each time that it has been suggested for several reasons: it
would break PAGE_SIZE assumptions across the kernel, it makes page-table
abstractions really expensive, and it does not provide any benefit on
architectures that do not support huge pages, incurring fast path
penalties without providing any benefit on these architectures.

This patch:

There are two means of creating mappings backed by huge pages:

        1. mmap() a file created on hugetlbfs
        2. Use shm which creates a file on an internal mount which essentially
           maps it MAP_SHARED

The internal mount is only used for shared mappings but there is very
little that stops it being used for private mappings. This patch extends
hugetlbfs_file_setup() to deal with the creation of files that will be
mapped MAP_PRIVATE on the internal hugetlbfs mount. This extended API is
used in a subsequent patch to implement the MAP_HUGETLB mmap() flag.

Subject: mm: add MAP_HUGETLB for mmaping pseudo-anonymous huge page regions

Add a flag for mmap that will be used to request a huge page region that
will look like anonymous memory to user space.  This is accomplished by
using a file on the internal vfsmount.  MAP_HUGETLB is a modifier of
MAP_ANONYMOUS and so must be specified with it.  The region will behave
the same as a MAP_ANONYMOUS region using small pages.

The patch also adds the MAP_STACK flag, which was previously defined only
on some architectures but not on others.  Since MAP_STACK is meant to be a
hint only, architectures can define it without assigning a specific
meaning to it.

Subject: hugetlb: add MAP_HUGETLB for mmaping pseudo-anonymous huge page
 regions

Add a flag for mmap that will be used to request a huge page region that
will look like anonymous memory to userspace.  This is accomplished by
using a file on the internal vfsmount.  MAP_HUGETLB is a modifier of
MAP_ANONYMOUS and so must be specified with it.  The region will behave
the same as a MAP_ANONYMOUS region using small pages.

Subject: mm: remove duplicate asm/mman.h files

A number of architectures have identical asm/mman.h files so they can all
be merged by using the new generic file.

The remaining asm/mman.h files are substantially different from each
other.

Subject: mm: move use_mm/unuse_mm from aio.c to mm/

Anyone who wants to do copy to/from user from a kernel thread, needs
use_mm (like what fs/aio has).  Move that into mm/, to make reusing and
exporting easier down the line, and make aio use it.  Next intended user,
besides aio, will be vhost-net.

Subject: mm: reduce atomic use on use_mm fast path

When the mm being switched to matches the active mm, we don't need to
increment and then drop the mm count.  In a simple benchmark this happens
in about 50% of time.  Making that conditional reduces contention on that
cacheline on SMP systems.

Subject: pcmcia: yenta: add missing __devexit marking

The remove member of the pci_driver yenta_cardbus_driver uses
__devexit_p(), so the remove function itself should be marked with
__devexit.  Even more so considering the probe function is marked with
__devinit.

Subject: nommu: add support for Memory Protection Units (MPU)

Some architectures (like the Blackfin arch) implement some of the
"simpler" features that one would expect out of a MMU such as memory
protection.

In our case, we actually get read/write/exec protection down to the page
boundary so processes can't stomp on each other let alone the kernel.

There is a performance decrease (which depends greatly on the workload)
however as the hardware/software interaction was not optimized at design
time.

Subject: alpha: convert to use arch_gettimeoffset()

Converts alpha to use GENERIC_TIME via the arch_getoffset()
infrastructure, reducing the amount of arch specific code we need to
maintain.

I suspect the alpha arch could even be further improved to provide and
rpcc() based clocksource, but not having the hardware, I don't feel
comfortable attempting the more complicated conversion (but I'd be glad to
help if anyone else is interested).

Subject: m32r: convert to use arch_gettimeoffset()

Convert m32r to use GENERIC_TIME via the arch_getoffset() infrastructure,
reducing the amount of arch specific code we need to maintain.

I also noted that m32r doesn't seem to be taking the xtime write lock
before calling do_timer()!  That looks like a pretty bad bug to me.  If
folks agree, let me know and I can move the lock grab to the correct spot.

Convert m68k to use GENERIC_TIME via the arch_getoffset() infrastructure,
reducing the amount of arch specific code we need to maintain.

I've taken my best swing at converting this, but I'm not 100% confident
I got it right. My cross-compiler is now out of date (gcc4.2) so I
wasn't able to  check if it compiled. Any assistance from arch
maintainers or testers to get this merged would be great.

Subject: cpuidle: fix the menu governor to boost IO performance

Fix the menu idle governor which balances power savings, energy efficiency
and performance impact.

The reason for a reworked governor is that there have been serious
performance issues reported with the existing code on Nehalem server
systems.

To show this I'm sure Andrew wants to see benchmark results:
(benchmark is "fio", "no cstates" is using "idle=poll")

		no cstates	current linux	new algorithm
1 disk		107 Mb/s	85 Mb/s		105 Mb/s
2 disks		215 Mb/s	123 Mb/s	209 Mb/s
12 disks	590 Mb/s	320 Mb/s	585 Mb/s

In various power benchmark measurements, no degredation was found by our
measurement&diagnostics team.  Obviously a small percentage more power was
used in the "fio" benchmark, due to the much higher performance.

While it would be a novel idea to describe the new algorithm in this
commit message, I cheaped out and described it in comments in the code
instead.

[changes since first post: spelling fixes from akpm, review feedback,
folded menu-tng into menu.c]

+/*
+ * Concepts and ideas behind the menu governor
+ *
+ * For the menu governor, there are 3 decision factors for picking a C
+ * state:
+ * 1) Energy break even point
+ * 2) Performance impact
+ * 3) Latency tolerance (from pmqos infrastructure)
+ * These these three factors are treated independently.
+ *
+ * Energy break even point
+ * -----------------------
+ * C state entry and exit have an energy cost, and a certain amount of time in
+ * the  C state is required to actually break even on this cost. CPUIDLE
+ * provides us this duration in the "target_residency" field. So all that we
+ * need is a good prediction of how long we'll be idle. Like the traditional
+ * menu governor, we start with the actual known "next timer event" time.
+ *
+ * Since there are other source of wakeups (interrupts for example) than
+ * the next timer event, this estimation is rather optimistic. To get a
+ * more realistic estimate, a correction factor is applied to the estimate,
+ * that is based on historic behavior. For example, if in the past the actual
+ * duration always was 50% of the next timer tick, the correction factor will
+ * be 0.5.
+ *
+ * menu uses a running average for this correction factor, however it uses a
+ * set of factors, not just a single factor. This stems from the realization
+ * that the ratio is dependent on the order of magnitude of the expected
+ * duration; if we expect 500 milliseconds of idle time the likelihood of
+ * getting an interrupt very early is much higher than if we expect 50 micro
+ * seconds of idle time. A second independent factor that has big impact on
+ * the actual factor is if there is (disk) IO outstanding or not.
+ * (as a special twist, we consider every sleep longer than 50 milliseconds
+ * as perfect; there are no power gains for sleeping longer than this)
+ *
+ * For these two reasons we keep an array of 12 independent factors, that gets
+ * indexed based on the magnitude of the expected duration as well as the
+ * "is IO outstanding" property.
+ *
+ * Limiting Performance Impact
+ * ---------------------------
+ * C states, especially those with large exit latencies, can have a real
+ * noticable impact on workloads, which is not acceptable for most sysadmins,
+ * and in addition, less performance has a power price of its own.
+ *
+ * As a general rule of thumb, menu assumes that the following heuristic
+ * holds:
+ *     The busier the system, the less impact of C states is acceptable
+ *
+ * This rule-of-thumb is implemented using a performance-multiplier:
+ * If the exit latency times the performance multiplier is longer than
+ * the predicted duration, the C state is not considered a candidate
+ * for selection due to a too high performance impact. So the higher
+ * this multiplier is, the longer we need to be idle to pick a deep C
+ * state, and thus the less likely a busy CPU will hit such a deep
+ * C state.
+ *
+ * Two factors are used in determing this multiplier:
+ * a value of 10 is added for each point of "per cpu load average" we have.
+ * a value of 5 points is added for each process that is waiting for
+ * IO on this CPU.
+ * (these values are experimentally determined)
+ *
+ * The load average factor gives a longer term (few seconds) input to the
+ * decision, while the iowait value gives a cpu local instantanious input.
+ * The iowait factor may look low, but realize that this is also already
+ * represented in the system load average.
+ *

Subject: cpuidle: menu governor: reduce latency on exit

Move the state residency accounting and statistics computation off the hot
exit path.

On exit, the need to recompute statistics is recorded, and new statistics
will be computed when menu_select is called again.

The expected effect is to reduce processor wakeup latency from sleep
(C-states).  We are speaking of few hundreds of cycles reduction out of a
several microseconds latency (determined by the hardware transition), so
it is difficult to measure.

From f5492666a3b62344de9026a960c11888160362c9 Mon Sep 17 00:00:00 2001
From: Joe Perches <joe@perches.com>

Subject: scripts/get_maintainer.pl: add --git-blame

Julia Lawall suggested that get_maintainers.pl should have the
ability to include signatories of commits that are modified by
a particular patch.

Vegard Nossum did something similar once.
http://lkml.org/lkml/2008/5/29/449

The modified script looks the commits for all lines in the
patch, and includes the "-by:" signatories for those commits.
It uses the same git-min-percent, git-max-maintainers, and
git-min-signatures options.  git-since is ignored.

It can be used independently from the --git default, so
        ./scripts/get_maintainers.pl --nogit --git-blame <patch>
or
        ./scripts/get_maintainers.pl --nogit --git-blame -f <file>
is acceptable.

If used with -f <file>, all lines/commits for the file are
checked.

--git-blame can be slow if used with -f <file>
--git-blame does not work with -f <directory>

Subject: scripts/get_maintainer.pl: add sections in pattern match depth order

Before this change, matched sections were added in the order
of appearance in the normally alphabetic section order of
the MAINTAINERS file.

For instance, finding the maintainer for drivers/scsi/wd7000.c
would first find "SCSI SUBSYSTEM", then "WD7000 SCSI SUBSYSTEM",
then "THE REST".

before patch:

$ ./scripts/get_maintainer.pl --nogit -f drivers/scsi/wd7000.c
James E.J. Bottomley <James.Bottomley@HansenPartnership.com>
Miroslav Zagorac <zaga@fly.cc.fer.hr>
linux-scsi@vger.kernel.org
linux-kernel@vger.kernel.org

get_maintainer.pl now selects matched sections by longest pattern match.
Longest is the number of "/"s and any specific file pattern.

This changes the example output order of MAINTAINERS to whatever is
selected in "WD7000 SUBSYSTEM", then "SCSI SYSTEM", then "THE REST".

after patch:

$ ./scripts/get_maintainer.pl --nogit -f drivers/scsi/wd7000.c

Subject: scripts/get_maintainer.pl: add --pattern-depth

--pattern-depth is used to control how many levels of directory traversal
should be performed to find maintainers.  default is 0 (all directory levels).

For instance:

MAINTAINERS currently has multiple M: and F: entries that match
net/netfilter/ipvs/ip_vs_app.c

IPVS
M:	Wensong Zhang <wensong@linux-vs.org>
M:	Simon Horman <horms@verge.net.au>
M:	Julian Anastasov <ja@ssi.bg>
[...]
F:	net/netfilter/ipvs/

NETFILTER/IPTABLES/IPCHAINS
[...]
M:	Patrick McHardy <kaber@trash.net>
[...]
F:	net/netfilter/

NETWORKING [GENERAL]
M:	"David S. Miller" <davem@davemloft.net>
[...]
F:	net/

THE REST
M:	Linus Torvalds <torvalds@linux-foundation.org>
[...]
F:	*/

Using this command will return all of those maintainers:
(except Linus unless --git-chief-maintainers is specified)

$ ./scripts/get_maintainer.pl --nogit -nol \
	-f net/netfilter/ipvs/ip_vs_app.c
Julian Anastasov <ja@ssi.bg>
Simon Horman <horms@verge.net.au>
Wensong Zhang <wensong@linux-vs.org>
Patrick McHardy <kaber@trash.net>
David S. Miller <davem@davemloft.net>

Adding --pattern-depth=1 will match at the deepest level
$ ./scripts/get_maintainer.pl --nogit -nol --pattern-depth=1 \
	-f net/netfilter/ipvs/ip_vs_app.c
Julian Anastasov <ja@ssi.bg>
Simon Horman <horms@verge.net.au>
Wensong Zhang <wensong@linux-vs.org>

Adding --pattern-depth=2 will match at the deepest level and 1 higher
$ ./scripts/get_maintainer.pl --nogit -nol --pattern-depth=2 \
	-f net/netfilter/ipvs/ip_vs_app.c
Julian Anastasov <ja@ssi.bg>
Simon Horman <horms@verge.net.au>
Wensong Zhang <wensong@linux-vs.org>
Patrick McHardy <kaber@trash.net>

and so on.

Added format_email and parse_email routines to reduce inline use.

Added email_address_inuse to eliminate multiple maintainer entries
for the same email address, the first name encountered is used.

Used internal perl equivalents of shell cmd use of grep|cut|sort|uniq

Subject: scripts/get_maintainer.pl: add --remove-duplicates

Allow control over the elimination of duplicate email names and addresses

--remove-duplicates will use the first email name or address presented
--noremove-duplicates will emit all names and addresses

--remove-duplicates is enabled by default

For instance:

$ ./scripts/get_maintainer.pl -f drivers/char/tty_ioctl.c
Greg Kroah-Hartman <gregkh@suse.de>
Alan Cox <alan@linux.intel.com>
Mike Frysinger <vapier@gentoo.org>
Alexey Dobriyan <adobriyan@gmail.com>
linux-kernel@vger.kernel.org

$ ./scripts/get_maintainer.pl -f --noremove-duplicates drivers/char/tty_ioctl.c
Greg Kroah-Hartman <gregkh@suse.de>
Alan Cox <alan@redhat.com>
Alan Cox <alan@linux.intel.com>
Alan Cox <alan@lxorguk.ukuu.org.uk>
Mike Frysinger <vapier@gentoo.org>
Alexey Dobriyan <adobriyan@gmail.com>
linux-kernel@vger.kernel.org

Using --remove-duplicates could eliminate multiple maintainers that
share the same name but not the same email address.

Subject: scripts/get_maintainer.pl: add maintainers in order listed in matched
 section

Previous behavior was "bottom-up" in each section from the pattern "F:"
entry that matched.  Now information is entered into the various lists in
the "as entered" order for each matched section.

This also allows the F: entry to be put anywhere in a section, not just as
the last entries in the section.

And a couple of improvements:

Don't alphabetically sort before outputting the matched scm, status,
subsystem and web sections.

Ignore content after a single email address so these entries are acceptable
M:	name <address> whatever other comment

And a fix:

Make an M: entry without a name again use the name from an immediately
preceding P: line if it exists.

Subject: flex_array: add flex_array_clear function

Add a new function to the flex_array API:

	int flex_array_clear(struct flex_array *fa,
				unsigned int element_nr)

This function will zero the element at element_nr in the flex_array.

Although this is equivalent to using flex_array_put() and passing a
pointer to zero'd memory, flex_array_clear() does not require such a
pointer to memory that would most likely need to be allocated on the
caller's stack which could be significantly large depending on
element_size.

Subject: flex_array: poison free elements

Newly initialized flex_array's and/or flex_array_part's are now poisoned
with a new poison value, FLEX_ARRAY_FREE.  It's value is similar to
POISON_FREE used in the various slab allocators, but is different to
distinguish between flex array's poisoned kmem and slab allocator poisoned
kmem.

This will allow us to identify flex_array_part's that only contain free
elements (and free them with an addition to the flex_array API).  This
could also be extended in the future to identify `get' uses on elements
that have not been `put'.

If __GFP_ZERO is passed for a part's gfp mask, the poisoning is avoided.
These elements are considered to be in-use since they have been
initialized.

Subject: flex_array: add flex_array_shrink function

Add a new function to the flex_array API:

	int flex_array_shrink(struct flex_array *fa)

This function will free all unused second-level pages.  Since elements are
now poisoned if they are not allocated with __GFP_ZERO, it's possible to
identify parts that consist solely of unused elements.

flex_array_shrink() returns the number of pages freed.

Subject: flex_array: introduce DEFINE_FLEX_ARRAY

FLEX_ARRAY_INIT(element_size, total_nr_elements) cannot determine if
either parameter is valid, so flex arrays which are statically allocated
with this interface can easily become corrupted or reference beyond its
allocated memory.

This removes FLEX_ARRAY_INIT() as a struct flex_array initializer since no
initializer may perform the required checking.  Instead, the array is now
defined with a new interface:

	DEFINE_FLEX_ARRAY(name, element_size, total_nr_elements)

This may be prefixed with `static' for file scope.

This interface includes compile-time checking of the parameters to ensure
they are valid.  Since the validity of both element_size and
total_nr_elements depend on FLEX_ARRAY_BASE_SIZE and FLEX_ARRAY_PART_SIZE,
the kernel build will fail if either of these predefined values changes
such that the array parameters are no longer valid.

Since BUILD_BUG_ON() requires compile time constants, several of the
static inline functions that were once local to lib/flex_array.c had to be
moved to include/linux/flex_array.h.

Impact:
  - More verbose help/usage message.
  - Make the option -f an alias for --file.
  - On -h, --help, and --version display help message and exit(0).
  - With no FILE(s) given, exit(1) with "no input files".
  - On invalid options display help/usage and exit(1).

Based on a patch by Pavel Machek.

Subject: drivers/hwmon/coretemp.c: enable the Intel Atom
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Enable the coretemp driver on an Intel Atom.

I'm not sure if the readings are correct, however - on my 330, the driver
reports values between 27 and 41 °C (with core1 being about 8°C hotter
than core0, given the same load).  Maybe the maximum temperature of 100 °C
is wrong for Atom CPUs.

Subject: lis3: add power management functions

This enabled power management functions for the SPI transport layer of the
lis3 devices.  The device's suspend mode is only entered in case no wakeup
threshold has been given.  In this case, the device is supposed to wake up
the system and must thus not be put to deep sleep.

Subject: drivers/hwmon/adm1021.c: support high precision ADM1023 remote sensor

The ADM1023 temperature sensor supports higher resolution for its external
sensor (sensitivity of 1/8 deg C).  This patch makes this higher
resolution available through the appropriate temperature sysfs nodes.

Curiously, this functionality was available in the 2.4 kernel driver (but
formatted in a less helpful manner).

Occasionally it is helpful to be able to turn a temperature sensor off
(for example if it's making unwanted electrical noise).  This patch
adds a sysfs node to put any adm1021 compatible device into low power mode.

Subject: hwmon: applesmc: restore accelerometer and keyboard backlight on
 resume

On resume from suspend, the driver currently resets the logical state as
if it was brought up from halt.  This patch uses the
dev_pm_ops.resume/restore methods to synchronize the hardware with the
memorized logical state, in effect bringing back the accelerometer and
backlight to the state prior to suspend.  Works for both suspend to ram
and hibernation.  The patch has zero effect on the running state.

Subject: m32r: make PAGE_SIZE available to assembly.

page.h includes ifndef __ASSEMBLY__ guards, but PAGE_SIZE is defined
using "1UL", which the assembler does not support. Use the _AC macro
from const.h to make it available to assembly (and linker scripts).

Subject: m32r: Define THREAD_SIZE only once.

Previously, m32r's asm/thread_info.h defined THREAD_SIZE differently
for assembly and C code; now that PAGE_SIZE is usable from assembly,
these can be combined.  Also, m32r's asm/processor.h redefines
THREAD_SIZE to the same value; remove this redundant definition.

Subject: m32r: Move GET_THREAD_INFO definition out of asm/thread_info.h.

Previously, asm/thread_info.h was not usable from linker scripts
because it contains a piece of .macro code.  Since that code was only
used in the m32r entry.S, the right fix is probably to move the macro
there.

Subject: m32r: Remove unused .altinstructions and .exit.* code from linker
 script.

It appears that m32r copied the .altinstructions definition from x86
when the architecture was first merged into Linux.  m32r doesn't put
anything in .altinstructions, so this is just dead code.

The following block affecting .exit.text/.exit.data, which has a
comment also copied from x86, should also be deleted; the linker
script later discards the .exit.text and .exit.data sections.

Subject: m32r: Move the spi_stack_top and spu_stack_top into .init.data
 section.

Since these get squashed into the .data output section by the m32r
linker script, it seems likely that they don't need their own input
sections.

At Hirokazu Takata's suggestion, we place these structures in
.init.data rather than just placing them in .data (since they are only
used at init time).

This patch is preparation for cleaning up the m32r architecture to use
the new macros in vmlinux.lds.h; if these sections are indeed not
needed, then we can use the RW_DATA_SECTION macro for m32r and save a
bunch of redundant code.

Subject: m32r: Cleanup linker script using new linker script macros.

This patch is largely a straightforward conversion.  One thing to note
is that the new macros use fewer separate output sections than the old
code; this should have no functional impact but is relevant for people
objdumping vmlinux files.

Also note that it moves the .data.init_task output sections inside
_edata.

Subject: x86: mce: Clean up thermal throttling state tracking code

Instead of a mess of three separate percpu variables, consolidate
the state into a single structure.

Also clean up therm_throt_process(), use cleaner and more
understandable variable names and a clearer logic.

This, without changing the logic, makes the code more
streamlined, more readable and smaller as well:

Subject: x86: mce: Fix thermal throttling message storm

If a system switches back and forth between hot and cold mode,
the MCE code will print a stream of critical kernel messages.

Extend the throttling code to properly notice this, by
only printing the first hot + cold transition and omitting
the rest up to CHECK_INTERVAL (5 minutes).

This way we'll only get a single incident of:

 [  102.356584] CPU0: Temperature above threshold, cpu clock throttled (total events = 1)
 [  102.357000] Disabling lock debugging due to kernel taint
 [  102.369223] CPU0: Temperature/speed normal

Every 5 minutes. The 'total events' count tells the number of cold/hot
transitions detected, should overheating occur after 5 minutes again:

[  402.357580] CPU0: Temperature above threshold, cpu clock throttled (total events = 24891)
[  402.358001] CPU0: Temperature/speed normal
[  450.704142] Machine check events logged

After a balance it is briefly possible for the space info
field in the inode to be NULL.  This adds some checks
to make sure things properly deal with the NULL value.

Subject: Btrfs: fix early enospc during balancing

We now do extra checks before a balance to make sure
there is room for the balance to take place.  One of
the checks was testing to see if we were trying to
balance away the last block group of a given type.

If there is no space available for new chunks, we
should not try and balance away the last block group
of a give type.  But, the code wasn't checking for
available chunk space, and so it was exiting too soon.

The fix here is to combine some of the checks and make
sure we try to allocate new chunks when we're balancing
the last block group.

Subject: x86: mce, inject: Use real inject-msg in raise_local

Current raise_local() uses a struct mce that comes from mce_write()
as a parameter instead of the real inject-msg, so when we set
mce.finished = 0 to clear injected MCE, the real inject stays
valid.

This will cause the remaining inject-msg affect the next injection,
which is not desired.

To fix this, real inject-msg is used in raise_local instead of the
one on the stack.

This patch is based on the diagnosis and the fixes by Dean Nelson.

time renames it to "mmci.h", and also the struct in this file

Date: Tue, 22 Sep 2009 14:41:40 +0100
Subject: ARM: 5721/1: MMCI enable the use of a regulator

This enables the use of a regulator to power the MMCI/PL180
PrimeCell. The OCR mask is calculated and voltage is set using
the new MMC core functions for discovering voltage ranges
in regulators. The platform translate_vdd function which basically
controls the 4 lines out of the PL180 is disabled if you use a
regulator instead.

Subject: [S390] cio: merge init calls

Define initialization sequence of css and ccw bus init calls by merging
them into a single init call. Also introduce channel_subsystem_init_sync
to wait for the initialization of devices to finish.

Subject: [S390] cio: introduce css_settle

Introduce the css_driver callback settle which can be implemented
by a subchannel driver to wait for the subchannel type specific
asynchronous work to finish.
In channel_subsystem_init_sync we call that for each subchannel
driver.

The functions idset_sch_new and for_each_subchannel_staged
use different values for the number of subchannel sets. Make
it consistent by changing idset_sch_new to also use the actual
number of subchannel sets.

Previously, there were multiple subchannel scanning mechanisms
which could potentially conflict with each other. Fix this problem
by moving blacklist and ccw driver triggered scanning to the
existing evaluation method.

Subject: [S390] qdio: reduce per device debug messages

Even if turned off the debug message overhead is measurable in the hot path.
Reduce the number of debug message calls in do_QDIO and qdio_kick_handler.
Also use hex numbers to save space in the debug entries.

Subject: [S390] qdio: change state of all primed input buffers

If input buffers stay in primed state qdio may not receive further interrupts
for the input queue depending on the firmware. That can cause a connection
hang on OSA cards.

Change the state of all primed input buffers that are not acknowledged to
not initialized.

Subject: [S390] hibernation: fix guest page hinting related crash

On resume the system that loads the to be resumed image might have
unstable pages.
When the resume image is copied back and a write access happen to an
unstable page this causes an exception and the system crashes.

To fix this set all free pages to stable before copying the resumed
image data. Also after everything has been restored set all free
pages of the resumed system to unstable again.

arch_ptrace on s390 implements PTRACE_(PEEK|POKE)(TEXT|DATA) instead of
using using ptrace_request in kernel/ptrace.c.
The only reason is the 31bit addressing mode, where we have to unmask the
highest bit.

Subject: [S390] hibernate: make sure pfn_is_nosave handles lowcore pages

pfn_is_nosave doesn't return the correct value for the second lowcore
page if lowcore protection is enabled. Make sure it always returns
the correct value.

While at it simplify the whole thing.
NSS special handling is done by the tprot check like it already works
for DCSS as well. So remove the extra code for NSS.

Subject: [S390] zcrypt: Do not add/remove devices in s/r callbacks

Devices are no longer removed or added in the suspend and resume
callbacks. Instead they are marked unregistered in suspend. In the
resume callback the ap_scan_bus method is scheduled. The bus scan
function will remove the old device and add new ones. This way all
the device handling will be done in only one function. Additionaly
the case where the domain might change during suspend/resume is
caught. In that case the devices qid needs to re-calculated in
order of having it found by the scan method.

Subject: [S390] dasd: tolerate devices that have no feature codes

The DASD device driver reads the feature codes of a device during
device initialization. These codes are later used to determine the
availability of advanced features like PAV or High Performance FICON.
Some very old devices do not support the command to read feature
codes and the initialization routine fails.
As the feature codes are not necessary for basic DASD operations, we
can support such devices by just ignoring missing feature codes.

Subject: [S390] hibernate: Do real CPU swap at resume time

Currently, when the physical resume CPU is not equal to the physical suspend
CPU, we swap the CPUs logically, by modifying the logical/physical CPU mapping.
This has two major drawbacks: First the change is visible from user space (e.g.
CPU sysfs files) and second it is hard to ensure that nowhere in the kernel
the physical CPU ID is stored before suspend.
To fix this, we now really swap the physical CPUs, if the resume CPU is not
the pysical suspend CPU. We restart the suspend CPU and stop the resume CPU
using SIGP restart and SIGP stop. If the suspend CPU is no longer available,
we write a message and load a disabled wait PSW.

'if (i < NR_INFO)' will only true if we breaks from 'for (i = 0; i < NR_INFO; i++)'
So removing useless 'if (i < NR_INFO)'

This also fixed following compilation warning :

Fix minor bug in netdev tx timeout handling which could
always lead to firmware reset instead of pci function reset.

netxen_nic_reset_context() requires __NX_RESETTING bit
cleared.

Jens Rosenboom noticed that a possibly unaligned const char*
is cast to a const struct in6_addr *.

Avoid this at the cost of a struct in6_addr copy on the stack.

Subject: kaweth: Fix memory leak in kaweth_control()

kaweth_control() never frees the buffer that it allocates for the USB
control message.  Test case:

while :; do ifconfig eth2 down ; ifconfig eth2 up ; done

This is a tiny buffer so it is a slow leak.  If you want to speed up the
process, you can change the allocation size to e.g. 16384 bytes, and it
will consume several megabytes within a few minutes.

The SKY2_HW_RAM_BUFFER bit in hw->flags was checked in sky2_mac_init(),
 before being set later in sky2_up().

Setting SKY2_HW_RAM_BUFFER in sky2_init() where other hw->flags are set
 should avoid this problem recurring.

+Regulator API design notes
+==========================
+
+This document provides a brief, partially structured, overview of some
+of the design considerations which impact the regulator API design.
+
+Safety
+------
+
+ - Errors in regulator configuration can have very serious consequences
+   for the system, potentially including lasting hardware damage.
+ - It is not possible to automatically determine the power confugration
+   of the system - software-equivalent variants of the same chip may
+   have different power requirments, and not all components with power
+   requirements are visible to software.
+
+  => The API should make no changes to the hardware state unless it has
+     specific knowledge that these changes are safe to do perform on
+     this particular system.
+
+Consumer use cases
+------------------
+
+ - The overwhelming majority of devices in a system will have no
+   requirement to do any runtime configuration of their power beyond
+   being able to turn it on or off.
+
+ - Many of the power supplies in the system will be shared between many
+   different consumers.
+
+  => The consumer API should be structured so that these use cases are
+     very easy to handle and so that consumers will work with shared
+     supplies without any additional effort.

Subject: smsc95xx: fix transmission where ZLP is expected

Usbnet framework assumes USB hardware doesn't handle zero length
packets, but SMSC LAN95xx requires these to be sent for correct
operation.

This patch fixes an easily reproducible tx lockup when sending a frame
that results in exactly 512 bytes in a USB transmission (e.g. a UDP
frame with 458 data bytes, due to IP headers and our USB headers).  It
adds an extra flag to usbnet for the hardware driver to indicate that
it can handle and requires the zero length packets.

This patch should not affect other usbnet users, please also consider
for -stable.

  ld: Warning: size of symbol `debug' changed from 90 in
arch/x86/built-in.o to 4 in drivers/built-in.o
 make: *** [vmlinux.o] Error 1

This is because recent saa7164 changes introduced a global symbol
named 'debug'. The x86 platform code already defines a 'debug'
symbol. (which is named in a too generic way as well - but it
can be used nicely to weed out too generic symbols in drivers ;-)

Rename it to saa_debug.

Subject: drm/i915: Add tracepoints

By adding tracepoint equivalents for WATCH_BUF/EXEC we are able to monitor
the lifetimes of objects, requests and significant events. These events can
then be probed using the tracing frameworks, such as systemtap and, in
particular, perf.

For example to record the stack trace for every GPU stall during a run, use

  $ perf record -e i915:i915_gem_request_wait_begin -c 1 -g

And

  $ perf report

to view the results.

[Updated to fix compilation issues caused.]

From ab5ee57650165dc342a20d1213d48d585f2a72bd Mon Sep 17 00:00:00 2001
From: Chris Wilson <chris@chris-wilson.co.uk>
Date: Sun, 20 Sep 2009 19:25:47 +0100
Subject: drm/i915: Clean up evict from list.

First the routine attempted to unlock a mutex it did not own along the
error path.

Secondly the routine should never be called on any list but the inactive
one, since we attempt to unbind those objects, so fix the calling semantics.

Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

Subject: drm/i915: Search harder for a reusable object

As evict_something() is called by routines that do not repeatedly search
again, try harder in the initial search to find an object that matches
the request.

Subject: drm/i915: Do not mis-classify clean objects as purgeable

Whilst cleaning up the patches for submission, I mis-classified non-dirty
objects as purgeable. This was causing the backing pages for those
objects to be evicted under memory-pressure, discarding valid and
unreplaceable texture data.

Subject: V4L/DVB (13037): go7007: Revert compatibility code added at the wrong
 place

Compatibility code is not allowed upstream. While this could
eventually be useful by out-of-tree compilation, directly from
http://linuxtv.org/hg/v4l-dvb tree, the compatibility code is at
the wrong place. In a matter of fact, it is not needed at all, since
compat.h already handles such things.

Subject: V4L/DVB (13038): dvbdev: Remove an anoying/uneeded warning

As pointed by Marcin Slusarz <marcin.slusarz@gmail.com>, the warns happens
because CONFIG_DVB_MAX_ADAPTERS depends on CONFIG_DVB_CORE, and there are
valid configs where DVB_CORE is not selected.

This causes such warnings, for every V4L and common drivers that may or
may not be compiled with DVB support:

drivers/media/dvb/dvb-core/dvbdev.h:36:2: warning: #warning invalid CONFIG_DVB_MAX_ADAPTERS value

We can safely remove the warning.

Subject: V4L/DVB (13039): dib0700: not building CONFIG_DVB_TUNER_DIB0070
 breaks compilation

As reported by Ingo Molnar:
 Here's another new build breakage that triggers in -tip testing:

 drivers/built-in.o:(.data+0xb1f40): undefined reference to `dib0070_ctrl_agc_filter'
 drivers/built-in.o:(.data+0xb1f80): undefined reference to `dib0070_ctrl_agc_filter'

triggers due to:

CONFIG_DVB_USB_DIB0700=y
CONFIG_DVB_TUNER_DIB0070 is not set

While working on a better approach, for now, let's just select tuner
dib0070 anytime we compile dib0700.

Subject: drm/i915: Handle ERESTARTSYS during page fault

During a page fault and rebinding the buffer there exists a window for a
signal to arrive during the i915_wait_request() and trigger a
ERESTARTSYS. This used to be handled by returning SIGBUS and thereby
killing the application. Try 'cairo-perf-trace & cairo-test-suite' and
watch X go boom!

The solution as suggested by H. Peter Anvin is to simply return NOPAGE and
leave the higher layers to spot we did not fill the page and resubmit
the page fault.

Subject: asm-generic: syscall_get_nr returns int

Only 32 bits of system call number are meaningful, so make the
specification for syscall_get_nr() be to return int, not long.

In meta downconvert, we need to checkpoint the metadata in an inode.
For refcount tree, we also need it. So abstract the process out.

Subject: ocfs2: Add caching info for refcount tree.

refcount tree should use its own caching info so that when
we downconvert the refcount tree lock, we can drop all the
cached buffer head.

From: Tao Ma <tao.ma@oracle.com>
Date: Mon, 24 Aug 2009 11:13:37 +0800
Subject: ocfs2: Add refcount tree lock mechanism.

Implement locking around struct ocfs2_refcount_tree.  This protects
all read/write operations on refcount trees.  ocfs2_refcount_tree
has its own lock and its own caching_info, protecting buffers among
multiple nodes.

User must call ocfs2_lock_refcount_tree before his operation on
the tree and unlock it after that.

ocfs2_refcount_trees are referenced by the block number of the
refcount tree root block, So we create an rb-tree on the ocfs2_super
to look them up.

Subject: ocfs2: Wrap ocfs2_extent_contig in ocfs2_extent_tree.

Add a new operation eo_ocfs2_extent_contig int the extent tree's
operations vector. So that with the new refcount tree, We want
this so that refcount trees can always return CONTIG_NONE and
prevent extent merging.

Date: Tue, 18 Aug 2009 11:22:21 +0800
Subject: ocfs2: Abstract extent split process.

ocfs2_mark_extent_written actually does the following things:
1. check the parameters.
2. initialize the left_path and split_rec.
3. call __ocfs2_mark_extent_written. it will do:
   1) check the flags of unwritten
   2) do the real split work.
The whole process is packed tightly somehow. So this patch
will abstract 2 different functions so that future b-tree
operation can work with it.

1. __ocfs2_split_extent will accept path and split_rec and do
  the real split work.
2. ocfs2_change_extent_flag will accept a new flag and initialize
   path and split_rec.

So now ocfs2_mark_extent_written will do:
1. check the parameters.
2. call ocfs2_change_extent_flag.
   1) initalize the left_path and split_rec.
   2) check whether the new flags conflict with the old one.
   3) call __ocfs2_split_extent to do the split.

Subject: ocfs2: move tree path functions to alloc.h.

Now fs/ocfs2/alloc.c has more than 7000 lines. It contains our
basic b-tree operation. Although we have already make our b-tree
operation generic, the basic structrue ocfs2_path which is used
to iterate one b-tree branch is still static and limited to only
used in alloc.c. As refcount tree need them and I don't want to
add any more b-tree unrelated code to alloc.c, export them out.

Subject: ocfs2: Add support for incrementing refcount in the tree.

    Given a physical cpos and length, increment the refcount
in the tree. If the extent has not been seen before, a refcount
record is created for it. Refcount records may be merged or
split by this operation.

From 1823cb0b9fe5e6d48017ee3f92428f69c0235d87 Mon Sep 17 00:00:00 2001
From: Tao Ma <tao.ma@oracle.com>
Date: Tue, 18 Aug 2009 11:24:49 +0800
Subject: ocfs2: Add support of decrementing refcount for delete.

    Given a physical cpos and length, decrement the refcount
in the tree. If the refcount for any portion of the extent goes
to zero, that portion is queued for freeing.

Subject: ocfs2: Decrement refcount when truncating refcounted extents.

Add 'Decrement refcount for delete' in to the normal truncate
process. So for a refcounted extent record, call refcount rec
decrementation instead of cluster free.

From 6f70fa519976a379d72781d927cf8e5f5b05ec86 Mon Sep 17 00:00:00 2001

Subject: ocfs2: Add CoW support.

This patch try CoW support for a refcounted record.

the whole process will be:
1. Calculate how many clusters we need to CoW and where we start.
   Extents that are not completely encompassed by the write will
   be broken on 1MB boundaries.
2. Do CoW for the clusters with the help of page cache.
3. Change the b-tree structure with the new allocated clusters.

Subject: ocfs2: CoW refcount tree improvement.

During CoW, if the old extent record is refcounted, we allocate
som new clusters and do CoW. Actually we can have some improvement
here. If the old extent has refcount=1, that means now it is only
used by this file. So we don't need to allocate new clusters, just
remove the refcounted flag and it is OK. We also have to remove
it from the refcount tree while not deleting it.

Subject: ocfs2: Integrate CoW in file write.

When we use mmap, we CoW the refcountd clusters in
ocfs2_write_begin_nolock. While for normal file
io(including directio), we do CoW in
ocfs2_prepare_inode_for_write.

Subject: ocfs2: CoW a reflinked cluster when it is truncated.

When we truncate a file to a specific size which resides in a reflinked
cluster, we need to CoW it since ocfs2_zero_range_for_truncate will
zero the space after the size(just another type of write).

So we add a "max_cpos" in ocfs2_refcount_cow so that it will stop when
it hit the max cluster offset.

Subject: ocfs2: Add normal functions for reflink a normal file's extents.

2 major functions are added in this patch.

ocfs2_attach_refcount_tree will create a new refcount tree to the
old file if it doesn't have one and insert all the extent records
to the tree if they are not refcounted.

ocfs2_create_reflink_node will:
1. set the refcount tree to the new file.
2. call ocfs2_duplicate_extent_list which will iterate all the
   extents for the old file, insert it to the new file and increase
   the corresponding referennce count.

Subject: ocfs2: handle file attributes issue for reflink.

A reflink creates a snapshot of a file, that means the attributes
must be identical except for three exceptions - nlink, ino, and ctime.

As for time changes, Here is a brief description:

1. Source file:
   1) atime: Ignore. Let the lazy atime code handle that.
   2) mtime: don't touch.
   3) ctime: If we change the tree (adding REFCOUNTED to at least one
             extent), update it.
2. Destination file:
   1) atime: ignore.
   2) mtime: we want it to appear identical to the source.
   3) ctime: update.

The idea here is that an ls -l will show the same time for the
src and target - it shows mtime.  Backup software like rsync and tar
will treat the new file correctly too.

Subject: ocfs2: Return extent flags for xattr value tree.

With the new refcount tree, xattr value can also be refcounted
among multiple files. So return the appropriate extent flags
so that CoW can used it later.

Subject: ocfs2: Abstract duplicate clusters process in CoW.

We currently use pagecache to duplicate clusters in CoW,
but it isn't suitable for xattr case. So abstract it out
so that the caller can decide which method it use.

Subject: ocfs2: Remove inode from ocfs2_xattr_bucket_get_name_value.

In ocfs2_xattr_bucket_get_name_value, actually we only use
super_block. So use it.

Subject: ocfs2: Abstract the creation of xattr block.

In xattr reflink, we also need to create xattr block, so
abstract the process out.

Subject: ocfs2: Abstract ocfs2 xattr tree extend rec iteration process.

Currently we have ocfs2_iterate_xattr_buckets which can receive
a para and a callback to iterate a series of bucket. It is good.
But actually the 2 callers ocfs2_xattr_tree_list_index_block and
ocfs2_delete_xattr_index_block are almost the same. The only
difference is that the latter need to handle the extent record
also. So add a new function named ocfs2_iterate_xattr_index_block.
It can be given func callback which are used for exten record.
So now we only have one iteration function for the xattr index
block. Ane what's more, it is useful for our future reflink
operations.

Subject: ocfs2: Attach xattr clusters to refcount tree.

In ocfs2, when xattr's value is larger than OCFS2_XATTR_INLINE_SIZE,
it will be kept outside of the blocks we store xattr entry. And they
are stored in a b-tree also. So this patch try to attach all these
clusters to refcount tree also.

Subject: ocfs2: Call refcount tree remove process properly.

Now with xattr refcount support, we need to check whether
we have xattr refcounted before we remove the refcount tree.

Now the mechanism is:
1) Check whether i_clusters == 0, if no, exit.
2) check whether we have i_xattr_loc in dinode. if yes, exit.
2) Check whether we have inline xattr stored outside, if yes, exit.
4) Remove the tree.

Subject: ocfs2: Create an xattr indexed block if needed.

With reflink, there is a need that we create a new xattr indexed
block from the very beginning. So add a new parameter for
ocfs2_create_xattr_block.

Subject: ocfs2: Modify removing xattr process for refcount.

The old xattr value remove is quite simple, it just erase the
tree and free the clusters. But as we have added refcount support,
The process is a little complicated.

We have to lock the refcount tree at the beginning, what's more,
we may split the refcount tree in some cases, so meta/credits are
needed.

Subject: ocfs2: Don't merge in 1st refcount ops of reflink.

Actually the whole reflink will touch refcount tree 2 times:
1. It will add the clusters in the extent record to the tree if it
   isn't refcounted before.
2. It will add 1 refcount to these clusters when it add these
   extent records to the tree.

So actually we shouldn't do merge in the 1st operation since the 2nd
one will soon be called and we may have to split it again. Do a merge
first and split soon is a waste of time. So we only merge in the 2nd
round. This is done by adding a new internal __ocfs2_increase_refcount
and call it with "not-merge" for 1st refcount operation in reflink.

This also has a side-effect that we don't need to worry too much about
the metadata allocation in the 2nd round since it will only merge and
no split will happen for those records.

Subject: ocfs2: Make transaction extend more efficient.

In ocfs2_extend_rotate_transaction, op_credits is the orignal
credits in the handle and we only want to extend the credits
for the rotation, but the old solution always double it. It
is harmless for some minor operations, but for actions like
reflink we may rotate tree many times and cause the credits
increase dramatically. So this patch try to only increase
the desired credits.

Subject: ocfs2: Use proper parameter for some inode operation.

In order to make the original function more suitable for reflink,
we modify the following inode operations. Both are tiny.

1. ocfs2_mknod_locked only use dentry for mlog, so move it to
   the caller so that reflink can use it without dentry.
2. ocfs2_prepare_orphan_dir only want inode to get its ip_blkno.
   So use ip_blkno instead.

Subject: ocfs2: Create reflinked file in orphan dir.

reflink is a very complicated process, so it can't be integrated
into one transaction. So if the system panic in the operation, we
may leave a unfinished inode in the destication directory.

So we will try to create an inode in orphan_dir first, reflink it
to the src file and then move it to the destication file in the end.
In that way we won't be afraid of any corruption during the reflink.

This patch adds 2 functions for orphan_dir operation:
1. Create a new inode in orphand dir.
2. Move an inode to a target dir.

Note:
fsck.ocfs2 should work for us to remove the unfinished file in the
orphan_dir.

Subject: ocfs2: Add preserve to reflink.

reflink has 2 options for the destination file:
1. snapshot: reflink will attempt to preserve ownership, permissions,
   and all other security state in order to create a full snapshot.
2. new file: it will acquire the data extent sharing but will see the
   file's security state and attributes initialized as a new file.

So add the option to ocfs2.

Subject: ocfs2: Add ioctl for reflink.

The ioctl will take 3 parameters: old_path, new_path and
preserve and call vfs_reflink. It is useful when we backport
reflink features to old kernels.

From: Roland McGrath <roland@redhat.com>

Subject: x86: ptrace: sysret path should reach syscall_trace_leave

If TIF_SYSCALL_TRACE or TIF_SINGLESTEP is set while inside a syscall,
the path back to user mode should get to syscall_trace_leave.

This does happen in most circumstances.  The exception to this is on
the 64-bit syscall fastpath, when no such flag was set on syscall
entry and nothing else has punted it off the fastpath for exit.  That
one exit fastpath fails to check for _TIF_WORK_SYSCALL_EXIT flags.
This makes the behavior inconsistent with what 32-bit tasks see and
what the native 32-bit kernel always does, and what 64-bit tasks see
in all cases where the iret path is taken anyhow.

Perhaps the only example that is affected is a ptrace stop inside
do_fork (for PTRACE_O_TRACE{CLONE,FORK,VFORK,VFORKDONE}).  Other
syscalls with internal ptrace stop points (execve) already take the
iret exit path for unrelated reasons.

Test cases for both PTRACE_SYSCALL and PTRACE_SINGLESTEP variants are at:
http://sources.redhat.com/cgi-bin/cvsweb.cgi/~checkout~/tests/ptrace-tests/tests/syscall-from-clone.c?cvsroot=systemtap
http://sources.redhat.com/cgi-bin/cvsweb.cgi/~checkout~/tests/ptrace-tests/tests/step-from-clone.c?cvsroot=systemtap

There was no special benefit to the sysret path's special path to call
do_notify_resume, because it always takes the iret exit path at the end.
So this change just makes the sysret exit path join the iret exit path
for all the signals and ptrace cases.  The fastpath still applies to
the plain syscall-audit and resched cases.

Subject: x86: ptrace: do not sign-extend orig_ax on write

The high 32 bits of orig_ax will be ignored when it matters,
so don't fiddle them when setting it.

Subject: x86: ptrace: set TS_COMPAT when 32-bit ptrace sets orig_eax>=0

The 32-bit ptrace syscall on a 64-bit kernel (32-bit debugger on
32-bit task) behaves differently than a native 32-bit kernel.  When
setting a register state of orig_eax>=0 and eax=-ERESTART* when the
debugged task is NOT on its way out of a 32-bit syscall, the task will
fail to do the syscall restart logic that it should do.

Test case available at http://sources.redhat.com/cgi-bin/cvsweb.cgi/~checkout~/tests/ptrace-tests/tests/erestartsys-trap.c?cvsroot=systemtap

This happens because the 32-bit ptrace syscall sets eax=0xffffffff
when it sets orig_eax>=0.  The resuming task will not sign-extend this
for the -ERESTART* check because TS_COMPAT is not set.  (So the task
thinks it is restarting after a 64-bit syscall, not a 32-bit one.)

The fix is to have 32-bit ptrace calls set TS_COMPAT when setting
orig_eax>=0.  This ensures that the 32-bit syscall restart logic
will apply when the child resumes.

Subject: md: Improve name of threads created by md_register_thread

The management thread for raid4,5,6 arrays are all called
mdX_raid5, independent of the actual raid level, which is wrong and
can be confusion.

So change md_register_thread to use the name from the personality
unless no alternate name (like 'resync' or 'reshape') is given.

This is simpler and more correct.

Subject: md: remove unnecessary memset from multipath.

Recent commit bbba809e96539672f775a3d70102657d05816a5b
replaced mempool_create_kzalloc_pool with mempool_create_kmalloc_pool
plus a memset.
This memset is not needed (and we didn't need kzalloc in the first
place).
Ever field of the allocated structure (struct multipath_bh) is
initialised immediately except retry_list, and memset does not
initial a list_head anyway.

To remove the memset.

Subject: md: raid-1/10: fix RW bits manipulation

Recently Jens has changed bio_rw_flagged() logic by following
commit 1f98a13f623e0ef666690a18c1250335fc6d7ef1. Now it returns
bool instead of int. This broke raid1/raid10 RW bits manipulation logic.
One of visible result is BUG_ON triggering due to empty barrier
here scsi_lib.c:1108 scsi_setup_fs_cmnd()

Subject: modules, tracing: Remove stale struct marker signature from
 module_layout()

Linus reported this new build warning:

  kernel/module.c:2951: warning: ?struct marker? declared inside parameter list
  kernel/module.c:2951: warning: its scope is only this definition or declaration, which is probably not what you want

Caused by:

  fc53776: tracing: Remove markers

module_layout() is an artificial symbol with 'significant' symbols
listed in its argument list so that it gets a proper argument types
signature that modversions can pick up to decide whether a
module is version-compatible or not. If these dont match then we
wont even look at a module.

Remove the stale marker symbol.

Subject: ocfs2: __ocfs2_abort() should not enable panic for local mounts

In a clustered setup, we have to panic the box on journal abort. This is
because we don't have the facility to go hard readonly. With hard ro, another
node would detect node failure and initiate recovery.

Having said that, we shouldn't force panic if the volume is mounted locally.
This patch defers the handling to the mount option, errors.

Subject: ocfs2: Use buffer IO if we are appending a file.

In ocfs2_file_aio_write, we will prevent direct io if
we find that we are appending(changing i_size) and call
generic_file_aio_write_nolock. But actually O_DIRECT flag
is there and this function will call generic_file_direct_write
eventually which will update i_size and leave di->i_size
alone. The bug is
http://oss.oracle.com/bugzilla/show_bug.cgi?id=1173.

So this patch let ocfs2_direct_IO returns 0 directly if we
are appending so that buffered write will be called and
di->i_size get updated successfully. And this is also
what we want in ocfs2_file_aio_write.

The problem is that the box has no lapic enabled:

  [    0.042445] Local APIC not detected. Using dummy APIC emulation.

The below seems like the best fix. We disabled all lapic bits, except
the self-IPI-resend logic.

Subject: perf tools: Fix module symbol loading bug

Avi Kivity reported 'perf annotate' failures with modules, the
requested function was not annotated.

If there are no modules currently loaded, or the last module
scanned is not loaded, dso__load_modules() steps on the value from
dso__load_vmlinux(), so we happily load the kallsyms symbols on top
of what we've already loaded.

Fix that such that the total count of symbols loaded is returned.
Should module symbol load fail after parsing of vmlinux, is's a
hard failure, so do not silently fall-back to kallsyms.

Subject: virtio_pci: minor MSI-X cleanups

1) Rename vp_request_vectors to vp_request_msix_vectors, and take
   non-MSI-X case out to caller.
2) Comment weird pci_enable_msix API
3) Rename vp_find_vq to setup_vq.
4) Fix spaces to tabs
5) Make nvectors calc internal to vp_try_to_find_vqs()
6) Rename vector to msix_vector for more clarity.

Subject: virtio: make add_buf return capacity remaining

This API change means that virtio_net can tell how much capacity
remains for buffers.  It's necessarily fuzzy, since
VIRTIO_RING_F_INDIRECT_DESC means we can fit any number of descriptors
in one, *if* we can kmalloc.

VIRTIO_ID_9P is already defined in include/linux/virtio_9p.h
so use that definition instead.

Subject: virtio: add virtio IDs file

Virtio IDs are spread all over the tree which makes assigning new IDs
bothersome. Putting them together should make the process less error-prone.

Subject: virtio_blk: add support for cache flush

Recent qemu has added a VIRTIO_BLK_F_FLUSH flag to advertise that the
virtual disk has a volatile write cache that needs to be flushed.  In case
we see this feature implement tell the Linux block layer about the fact
and use the new VIRTIO_BLK_T_FLUSH to flush the cache when required.  This
allows for an correct and simple implementation of write barriers.

Subject: lguest: move panic notifier registration to its expected place.

We used to defer it, so lockdep was happy.  We now init lockdep early
anyway, so just do it after that.

Subject: lguest: use set_pte/set_pmd uniformly for real page table entries

If we're building a pte, we can use simple assigment; only use set_pte
etc. when we're actually going to use that destination as a PTE.  I
don't know that we'll ever run under Xen, but it's neater.

And use set_pte/set_pmd rather than assuming native_ versions, even
though that's probably true for most people.

Subject: lguest: don't force VIRTIO_F_NOTIFY_ON_EMPTY

VIRTIO_F_NOTIFY_ON_EMPTY indicates to the Guest that we will hit them with
an interrupt every time the xmit queue is emptied.

Because it results in lots of tx interrupts, modern Guests probably don't
want it, so let's only force it when they accept the option.

A few days ago i got the latest ZTE EVDO modem shown at:
http://img.alibaba.com/photo/240150115/ZTE_AC2726_EVDO_USB_Data_Modem.jpg

It seems that the latest kernel does not have support for it.
I wrote a small patch for the options.c module to add the relevant usb
ids to it.

SL811 Device detected after removal used to be working in linux-2.6.22
but then broke somewhere between 2.6.22 and 2.6.28. Current
hub_port_connect_change() in drivers/usb/core/hub.c won't call
usb_disconnect() in case the SL811 driver sets portstatus
USB_PORT_FEAT_CONNECTION upon removal.
AFAIK the SL811 has only a combined Device Insert/Remove
detection bit, therefore use a count to distinguish insert or remove.

Date: Fri, 7 Aug 2009 14:04:36 -0700
Subject: USB: xhci: Work around for chain bit in link TRBs.

Different sections of the xHCI 0.95 specification had opposing
requirements for the chain bit in a link transaction request buffer (TRB).
The chain bit is used to designate that adjacent TRBs are all part of the
same scatter gather list that should be sent to the device.  Link TRBs can
be in the middle, or at the beginning or end of these chained TRBs.

Sections 4.11.5.1 and 6.4.4.1 both stated the link TRB "shall have the
chain bit set to 1", meaning it is always chained to the next TRB.
However, section 4.6.9 on the stop endpoint command has specific cases for
what the hardware must do for a link TRB with the chain bit set to 0.  The
0.96 specification errata later cleared up this issue by fixing the
4.11.5.1 and 6.4.4.1 sections to state that a link TRB can have the chain
bit set to 1 or 0.

The problem is that the xHCI cancellation code depends on the chain bit of
the link TRB being cleared when it's at the end of a TD, and some 0.95
xHCI hardware simply stops processing the ring when it encounters a link
TRB with the chain bit cleared.

Allow users who are testing 0.95 xHCI prototypes to set a module parameter
(link_quirk) to turn on this link TRB work around.  Cancellation may not
work if the ring is stopped exactly on a link TRB with chain bit set, but
cancellation should be a relatively uncommon case.

Subject: USB: xhci: Configure endpoint code refactoring.

Refactor out the code issue, wait for, and parse the event completion code
for a configure endpoint command.  Modify it to support the evaluate
context command, which has a very similar submission process.  Add
functions to copy parts of the output context into the input context
(which will be used in the evaluate context command).

Subject: USB: xhci: Set correct max packet size for HS/FS control endpoints.

Set the max packet size for the default control endpoint on high speed
devices to be 64 bytes.  High speed devices always have a max packet size
of 64 bytes.  There's no use setting it to eight for the initial 8 byte
descriptor fetch and then issuing (and waiting for) an evaluate context
command to update it to 64 bytes for the subsequent control transfers.

The USB core guesses that the max packet size on a full speed control
endpoint is 64 bytes, and then updates it after the first 8-byte
descriptor fetch.  Change the initial setup for the xHCI internal
representation of the full speed device to have a 64 byte max packet size.

Subject: USB: xhci: Support full speed devices.

Full speed devices have varying max packet sizes (8, 16, 32, or 64) for
endpoint 0.  The xHCI hardware needs to know the real max packet size
that the USB core discovers after it fetches the first 8 bytes of the
device descriptor.

In order to fix this without adding a new hook to host controller drivers,
the xHCI driver looks for an updated max packet size for control
endpoints.  If it finds an updated size, it issues an evaluate context
command and waits for that command to finish.  This should only happen in
the initialization and device descriptor fetching steps in the khubd
thread, so blocking should be fine.

Subject: USB: xhci: Handle stalled control endpoints.

When a control endpoint stalls, the next control transfer will clear the
stall.  The USB core doesn't call down to the host controller driver's
endpoint_reset() method when control endpoints stall, so the xHCI driver
has to do all its stall handling for internal state in its interrupt handler.

When the host stalls on a control endpoint, it may stop on the data phase
or status phase of the control transfer.  Like other stalled endpoints,
the xHCI driver needs to queue a Reset Endpoint command and move the
hardware's control endpoint ring dequeue pointer past the failed control
transfer (with a Set TR Dequeue Pointer or a Configure Endpoint command).

Since the USB core doesn't call usb_hcd_reset_endpoint() for control
endpoints, we need to do this in interrupt context when we get notified of
the stalled transfer.  URBs may be queued to the hardware before these two
commands complete.  The endpoint queue will be restarted once both
commands complete.

Subject: USB: xhci: Add quirk for Fresco Logic xHCI hardware.

This Fresco Logic xHCI host controller chip revision puts bad data into
the output endpoint context after a Reset Endpoint command.  It needs a
Configure Endpoint command (instead of a Set TR Dequeue Pointer command)
after the reset endpoint command.

Set up the input context before issuing the Reset Endpoint command so we
don't copy bad data from the output endpoint context.  The HW also can't
handle two commands queued at once, so submit the TRB for the Configure
Endpoint command in the event handler for the Reset Endpoint command.

Devices that stall on control endpoints before a configuration is selected
will not work under this Fresco Logic xHCI host controller revision.

This patch is for prototype hardware that will be given to other companies
for evaluation purposes only, and should not reach consumer hands.  Fresco
Logic's next chip rev should have this bug fixed.

Subject: USB: xhci: Handle babbling endpoints correctly.

The 0.95 xHCI spec says that non-control endpoints will be halted if a
babble is detected on a transfer.  The 0.96 xHCI spec says all types of
endpoints will be halted when a babble is detected.  Some hardware that
claims to be 0.95 compliant halts the control endpoint anyway.

When a babble is detected on a control endpoint, check the hardware's
output endpoint context to see if the endpoint is marked as halted.  If
the control endpoint is halted, a reset endpoint command must be issued
and the transfer ring dequeue pointer needs to be moved past the stopped
transfer.  Basically, we treat it as if the control endpoint had stalled.

Handle bulk babbling endpoints as if we got a completion event with a
stall completion code.

On a successful transfer, urb->td is freed before the URB is ready to be
given back to the driver.  Don't touch urb->td after it's freed.  This bug
would have only shown up when xHCI debugging was turned on, and the freed
memory was quickly reused for something else.

Subject: USB: xhci: Support interrupt transfers.

Interrupt transfers are submitted to the xHCI hardware using the same TRB
type as bulk transfers.  Re-use the bulk transfer enqueueing code to
enqueue interrupt transfers.

Interrupt transfers are a bit different than bulk transfers.  When the
interrupt endpoint is to be serviced, the xHC will consume (at most) one
TD.  A TD (comprised of sg list entries) can take several service
intervals to transmit.  The important thing for device drivers to note is
that if they use the scatter gather interface to submit interrupt
requests, they will not get data sent from two different scatter gather
lists in the same service interval.

For now, the xHCI driver will use the service interval from the endpoint's
descriptor (bInterval).  Drivers will need a hook to poll at a more
frequent interval.  Set urb->interval to the interval that the xHCI
hardware will use.

Subject: USB: Fix SS endpoint companion descriptor parsing.

When there's a descriptor after the SuperSpeed endpoint companion
descriptor, the previous code would have skipped over twice the length it
was supposed to.  This code fixes crashes seen with UASP devices (which
have a UASP descriptor after the SS endpoint companion descriptor).

Subject: USB: sisusbvga: drop usb_buffer_alloc

This patch falls out of my work to fix usbmon so it uses virtual addresses.
It is not necessary, the "new" usbmon should work just fine with sisusbvga.
However, it seems ridiculous that anyone would use uncached memory to
transfer bulk data. Dropping the unnecessary use of usb_buffer_alloc
should be beneficial here, in case anyone ever uses the dongle on
anything beyond x86.

I had no success in raising the author of the driver by e-mail, so
the patch is not actually tested.

These statements seem to be unnecessary. No idea why, but I built all

It's an old patch that popped from discussion with Paul in November 2008.
Obviously not a very high priority but better late than never.

Subject: USB: usbmon: end ugly tricks with DMA peeking

This patch fixes crashes when usbmon attempts to access GART aperture.
The old code attempted to take a bus address and convert it into a
virtual address, which clearly was impossible on systems with actual
IOMMUs. Let us not persist in this foolishness, and use transfer_buffer
in all cases instead.

I think downsides are negligible. The ones I see are:
 - A driver may pass an address of one buffer down as transfer_buffer,
   and entirely different entity mapped for DMA, resulting in misleading
   output of usbmon. Note, however, that PIO based controllers would
   do transfer the same data that usbmon sees here.
 - Out of tree drivers may crash usbmon if they store garbage in
   transfer_buffer. I inspected the in-tree drivers, and clarified
   the documentation in comments.
 - Drivers that use get_user_pages will not be possible to monitor.
   I only found one driver with this problem (drivers/staging/rspiusb).
 - Same happens with with usb_storage transferring from highmem, but
   it works fine on 64-bit systems, so I think it's not a concern.
   At least we don't crash anymore.

Why didn't we do this in 2.6.10? That's because back in those days
it was popular not to fill in transfer_buffer, so almost all
traffic would be invisible (e.g. all of HID was like that).
But now, the tree is almost 100% PIO friendly, so we can do the
right thing at last.

Date: Thu, 11 Jun 2009 08:40:39 -0600
Subject: USB: Let usb_sg_init to set transfer_buffer more often

This fix permits the "new" usbmon to access usb-storage's data buffer
without DMA remapping tricks. It should be compatible with PIO controllers
and not add any new crashes. Note that from now on PIO controllers and
usbmon are uniform in their access pattern and if one crashes then
the other will too. Hopefuly neither does.

As a side effect, we get rid for #ifdefs, which were a little ugly.

Subject: USB audio gadget: Un-inline generic_[gs]et_cmd

Those functions are used only used to fill the set/get members of
usb_audio_control. It doesn't make much sense to inline them.

Subject: USB: whci-hcd: make endpoint_reset method async

usb_hcd_endpoint_reset() may be called in atomic context and must not
sleep.  So make whci-hcd's endpoint_reset() asynchronous.  URBs
submitted while the reset is in progress will be queued (on the std
list) and transfers will resume once the reset is complete.

From 7cbe5dca399a50ce8aa74314b1d276e2fb904e1b Mon Sep 17 00:00:00 2001
From: Alan Stern <stern@rowland.harvard.edu>

Subject: USB: add API for userspace drivers to "claim" ports

This patch (as1258) implements a feature that users have been asking
for: It gives programs the ability to "claim" a port on a hub, via a
new usbfs ioctl.  A device plugged into a "claimed" port will not be
touched by the kernel beyond the immediate necessities of
initialization and enumeration.

In particular, when a device is plugged into a "claimed" port, the
kernel will not select and install a configuration.  And when a config
is installed by usbfs or sysfs, the kernel will not probe any drivers
for any of the interfaces.  (However the kernel will fetch various
string descriptors during enumeration.  One could argue that this
isn't really necessary, but the strings are exported in sysfs.)

The patch does not guarantee exclusive access to these devices; it is
still possible for more than one program to open the device file
concurrently.  Programs are responsible for coordinating access among
themselves.

A demonstration program showing how to use the new interface can be
found in an attachment to

	http://marc.info/?l=linux-usb&m=124345857431452&w=2

The patch also makes a small simplification to the hub driver,
replacing a bunch of more-or-less useless variants of "out of memory"
with a single message.

From ccf5b801cef4f9e2d708d3b87e91e2bc6abd5206 Mon Sep 17 00:00:00 2001
From: Alan Stern <stern@rowland.harvard.edu>
Date: Mon, 29 Jun 2009 11:00:01 -0400
Subject: USB: make intf.pm_usage an atomic_t

This patch (as1260) changes the pm_usage_cnt field in struct
usb_interface from an int to an atomic_t.  This is so that drivers can
invoke the usb_autopm_get_interface_async() and
usb_autopm_put_interface_async() routines without locking and without
fear of corrupting the pm_usage_cnt value.

From 4c6e8971cbe0148085fcf6fd30eaa3c39f8a8cce Mon Sep 17 00:00:00 2001
From: Alan Stern <stern@rowland.harvard.edu>

Subject: USB: make the "usbfs_snoop" log more pertinent

This patch (as1261) reduces the amount of detailed URB information
logged by usbfs when the usbfs_snoop parameter is enabled.

Currently we don't display the final status value for a completed URB.
But we do display the entire data buffer twice: both before submission
and after completion.  The after-completion display doesn't limit
itself to the actual_length value.  But since usbmon is readily
available in virtually all distributions, there's no reason for usbfs
to print out any buffer contents at all!

So this patch restricts the information to: userspace buffer pointer,
endpoint number, type, and direction, length or actual_length, and
timeout value or status.  Now everything fits neatly into a single
line.

Along with those changes, the patch also fixes the snoop output for
the REAPURBNDELAY and REAPURBNDELAY32 ioctls.  The current version
omits the 'N' from the names.

Subject: USB: gadget: pxa25x: basic transceiver support

This adds very basic otg_transceiver support, with vbus_session
and vbus_draw callbacks.

Now VBUS sensing can be handled by an external driver which registers
the otg_transceiver interface. It also allows gadget drivers to configure
the current drawn from VBUS. The UDC driver just passes their requests
along to the transceiver driver.

Subject: USB: serial: full autosuspend support for the option driver

this adds autosupport usable even in an always online mode.

- enables remote wakeup on open
- autoresume for sending
- timeout based autosuspend if nothing is sent or recieved
- autosuspend without remote wakeup support on open/close

Subject: USB: EHCI: add need_io_watchdog flag to ehci_hcd

Basically the io watchdog is only useful for those quirk HCDs. For most
good ones, it only brings unnecessary wakeups.  At least, I know the
Intel EHCI HCDs should turn off the flag.

Subject: USB: EHCI: split ehci_qh into hw and sw parts

The ehci_qh structure merged hw and sw together which is not good:
1. More and more items are being added into ehci_qh, the ehci_qh software
   part are unnecessary to be allocated in DMA qh_pool.
2. If HCD has local SRAM, the sw part will consume it too, and it won't
   bring any benefit.
3. For non-cache-coherence system, the entire ehci_qh is uncachable, actually
   we only need the hw part to be uncacheable. Spliting them will let the sw
   part to be cacheable.

Subject: USB: EHCI: Add Intel Moorestown EHCI controller HOSTPCx extensions
 and support phy low power mode

The Intel Moorestown EHCI controller supports non-standard HOSTPCx register
extension. This register controls the LPM behaviour and controls the behaviour
of each USB port.

Subject: USB: isp1760: allow platform devices to customize devflags

Platform device support was merged earlier, but support for boards to
customize the devflags aspect of the controller was not.  We want this on
Blackfin systems to control the bus width, but might as well expose all of
the fields while we're at it.

if a subdriver has an additional suspend method, it must be called
first to allow the subdriver to return -EBUSY, because the second
half cannot be easily undone.

Subject: USB: check for hub driver not bound to root hub device

This patch (as1267) changes usb_kick_khubd() and hdev_to_hub() to make
them more resilient against situations where a hub device isn't bound
to the hub driver.  The code assumes that if a root hub was
successfully registered then it must be bound to the hub driver.

But this assumption can fail if the user manually unbinds the hub
driver, or more importantly, if the host controller dies causing
usb_set_configuration to fail.

To protect against these possibilities, make hdev_to_hub() check that
the hub device is configured before dereferencing the active
configuration, and make usb_kick_khubd() check that the pointer to the
hub's private data structure isn't NULL.

Subject: USB: don't lose mode switch events on suspended devices

This patch (as1268) changes the way usbcore handles child devices that
undergo a disconnection and reconnection while the parent hub is
suspended.  Currently, if the child isn't enabled for remote wakeup we
leave it alone, figuring that it will go through a reset-resume when
somebody tries to use it.

However this isn't a good approach if the reason for the disconnection
is that the child decided to switch modes or in some other way alter
its descriptors.  In that case we want to re-enumerate it as soon as
possible, not wait until somebody forces a reset-resume.

To resolve the issue, this patch treats reconnected suspended child
devices as though they had requested a remote wakeup, even if they
weren't enabled for it.  The mode switch or descriptor change will be
detected during the reset part of the reset-resume, and the device
will be re-enumerated immediately.

The disadvantage of this change is that it will cause autosuspended
devices to be resumed when the computer wakes up from a system sleep
during which the root hub was reset or lost power.  This shouldn't
matter much; some people would even argue that autosuspended devices
should _always_ be resumed when the system wakes up!

Subject: USB: dummy-hcd: accept mismatch between wLength and transfer length

This patch (as1269) fixes a bug in the way dummy_hcd handles control
URBs.  Currently it returns a -EOVERFLOW error if the wLength value in
the setup packet is different from the URB's transfer_buffer_length.

Other host controller drivers don't do this.  There's no reason the
two length values have to be equal, and in fact they sometimes aren't
-- a driver might set the transfer length to the maxpacket value in
order to handle buggy devices that don't respect wLength.

This patch simply removes the unnecessary check and error return.

Subject: USB: usbtmc: sanity checks for DEV_DEP_MSG_IN urbs

According to the specifications, an instrument should not return more data in a
DEV_DEP_MSG_IN urb than requested.  However, some instruments can send more
than requested. This could cause the kernel to write the extra data past the
end of the buffer provided by read().

Fix this by checking that the value of the TranserSize field is not larger than
the urb itself and not larger than the size of the userspace buffer. Also
correctly decrement the remaining size of the buffer when userspace read()s
more than USBTMC_SIZE_IOBUFFER.

Subject: USB: at91: Add USB EHCI driver for at91sam9g45 series

Add host USB High speed driver for at91sam9g45 series.
The host driver is an EHCI with its companion OHCI. EHCI is
handled by the new ehci-atmel.c whereas the OHCI is always
handled by ohci-at91.c.

At91sam9g45 series has a set of high speed USB interfaces.
The host driver is an EHCI with its companion OHCI. OHCI is
always handled by ohci-at91.c.
This wrapper is just modified to allow IRQ sharing
between two controllers.

Subject: USB: ohci-pxa27x: Allow NOCP and OCPM to be cleared

Some ohci-pxa27x platforms may require OCPM and NOCP in UHCRHDA to be
clear, but the existing code was only allowing setting.  This patch
ensures that these bits are clear if the respective flags are not set.
This is particularly important for the PXA3xx family where the
documentation says OCPM must be cleared, but it is set after reset.

Subject: USB: ark3116: add IrDA support for Gembird UIR-22

Add IrDA support to ark3116 driver.  This makes Gembird UIR-22 USB to IrDA
adapter work (vendor ID 0x18ec, device ID 0x3118).  This adapter contains
ARK3116T USB serial chip and an IrDA transceiver, thus a command like
"irattach /dev/ttyUSB0 -s" is needed.

All magic numbers were captured using usbsnoop from windows driver that
came with the device.

Subject: USB: usb-storage fails to attach to Huawei Datacard cdrom device

In this patch, we always make the return value of function
usb_stor_huawei_e220_init to be zero. Then it will not prevent usb-storage
driver from attaching to the CDROM device of Huawei Datacard.

Subject: USB: gadget: audio driver seg-fault fix

The included patch can be applied to the new usb gadget audio driver.

It addresses a seg-fault in uncovered in g_audio.ko.
The fault occurs in the function u_audio.c::gaudio_open_end_dev() when
device /dev/snd/pcmC0D0c (FILE_PCM_CAPTURE) is not present.

I suspect there may be similar problems with device /dev/snd/pcmC0D0p
(FILE_PCM_PLAYBACK) handling also.  I leave that for the developer(s),
as I was unsure as to the side-effects of not calling
playback_default_hw_params() in the initialization phase.

Subject: USB: increase usbdevfs max isoc buffer size

The current limit only allows isochronous transfers up to 32kbyte/urb,
updating this to 192 kbyte/urb improves the reliability of the
transfer. USB 2.0 transfer is possible with 32kbyte but increases the
chance of corrupted/incomplete data when the system is performing some
other tasks in the background.

Subject: USB: Work around BIOS bugs by quiescing USB controllers earlier

We are seeing a number of crashes in SMM, when VT-d is enabled while
'Legacy USB support' is enabled in various BIOSes.

The BIOS is supposed to indicate which addresses it uses for DMA in a
special ACPI table ("RMRR"), so that we can punch a hole for it when we
set up the IOMMU.

The problem is, as usual, that BIOS engineers are totally incompetent.
They write code which will crash if the DMA goes AWOL, and then they
either neglect to provide an RMRR table at all, or they put the wrong
addresses in it. And of course they don't do _any_ QA, since that would
take too much time away from their crack-smoking habit.

The real fix, of course, is for consumers to refuse to buy motherboards
which only have closed-source firmware available. If we had _open_
firmware, bugs like this would be easy to fix.

Since that's something I can only dream about, this patch implements an
alternative -- ensuring that the USB controllers are handed off from the
BIOS and quiesced _before_ the IOMMU is initialised. That would have
been a much better design than this RMRR nonsense in the first place, of
course. The bootloader has no business doing DMA after the OS has booted
anyway.

Since twl4030_usb USB transceiver .probe depends on
twl4030-regulator, marking twl4030_usb_init as subsys_initcall_sync
can make it called after twl4030-regulator initialization is finished,
then twl4030_usb USB transceiver driver can be probed successfully.

Subject: USB: EHCI: ensure all watchdog timer events are deleted when
 suspending usb

This patch was previously discussed in the following thread:
http://thread.gmane.org/gmane.linux.usb.general/19472/focus=19484

On the OMAP3 device the usbhost controller is in a separate internal
power-domain. So when the usbhost is inactive or suspend is called,
we can disable clocks and power-down the usbhost to save power.

Recently we found that after calling ehci_bus_suspend() and disabling
the usbhost clocks we would see the ehci watchdog timer event fire. This
was causing a kernel panic because the usbhost controllers clocks were
disabled and inside the watchdog timer function the clocks were not
being re-enabled, so when the ehci registers were accessed this resulted
in a CPU data-abort.

To avoid this panic, per recommendation from Alan Stern (see above thread), we
make sure any pending timer events (that may have been scheduled by calling
ehci_work within the ehci_bus_suspend() function) are deleted before returning.

Subject: USB: Fix CDC EEM host driver 'sentinel' CRC validation

This is an alternate solution to the EEM 'sentinel' CRC valiation issue.

CDC EEM allows using a 'sentinel' ethernet frame CRC of 0xdeadbeef in
place of a real CRC.  The 'sentinel' value is transmitted in big-endian
order whereas the normal CRC is little-endian.  This patch handles both
cases appropriately.

Subject: USB: otg: fix twl4030-usb build

subsys_initcall_sync() is only defined for built-in code, not for
loadable modules, so this driver build fails when built as a module.
However, the _sync() forms of the initcalls are not implemented,
so this should not be used -- just use the non-sync form of it.

drivers/usb/otg/twl4030-usb.c:777: warning: data definition has no type or storage class
drivers/usb/otg/twl4030-usb.c:777: warning: type defaults to 'int' in declaration of 'subsys_initcall_sync'
drivers/usb/otg/twl4030-usb.c:777: warning: parameter names (without types) in function declaration

Subject: USB: use kfifo to buffer usb-generic serial writes

When do_output_char() attempts to write a carriage return/line feed sequence,
it first checks to see how much buffer room is available. If there are at least
two characters free, it will write the carriage return/line feed with two calls
to tty_put_char(). It calls the tty_operation functions write() for devices that
don't support the tty_operations function put_char(). If the USB generic serial
device's write URB is not in use, it will return the buffer size when asked how
much room is available. The write() of the carriage return will cause it to mark
the write URB busy, so the subsequent write() of the line feed will be ignored.

This patch uses the kfifo infrastructure to implement a write FIFO that
accurately returns the amount of space available in the buffer.

Subject: USB: gadget: Add EEM gadget driver

This patch adds a CDC EEM ethernet gadget driver.  CDC EEM is a newer
USB ethernet specification that uses a simpler interface than the older
CDC ECM.  This makes CDC EEM usable by a wider set of USB hardware.
By default the ethernet gadget will still use CDC ECM/Subset, but kernel
configuration and/or a module parameter will allow alternative use of
the CDC EEM protocol.

Changes since last version:
	- Brought in missing RNDIS changes that caused compile error
	- Modified 'sentinel CRC' checking to match EEM host driver

+         CDC EEM is a newer USB standard that is somewhat simpler than CDC ECM
+         and therefore can be supported by more hardware.  Technically ECM and
+         EEM are designed for different applications.  The ECM model extends
+         the network interface to the target (e.g. a USB cable modem), and the
+         EEM model is for mobile devices to communicate with hosts using
+         ethernet over USB.  For Linux gadgets, however, the interface with
+         the host is the same (a usbX device), so the differences are minimal.
+
+         If you say "y" here, the Ethernet gadget driver will use the EEM
+         protocol rather than ECM.  If unsure, say "n".

Subject: USB: s3c2410: unregister should call unbind, not disconnect

This patch (as1275) fixes the s3c2410 device controller driver.  Its
usb_gadget_unregister_driver() routine is supposed to call the gadget
driver's unbind method, not the disconnect method.

Subject: USB-serial: pl2303: fix baud rate handling in case of unsupported
 values

According to the datasheets, the PL2303 supports a set of 25 baudrates.
The baudrate is set as a 4 byte value directly.

During my experiments with device 067b:2303 (PL2303X), I noticed that
 - the bridge-controller always uses 9600 baud if invalid/unsupported baud rate
   values are set
 - the baud rate value returned by usb_control_msg(..., GET_LINE_REQUEST, ...)
   does not reflect the actually used baudrate. Always the last set value is
   returned, even if it was invalid and not used by the controller.

This patch fixes the following issues with the current code:
1.) make sure that only supported baudrates are set (are there any buggy
    chip revisions out there which don't "like" other values... ?).
2.) always set the baudrate to the next nearest supported baudrate.
3.) applications can now read back the resulting baudrate properly, because
    tty_encode_baud_rate(...) is now fed with the actually used baudrate.

Subject: USB: EHCI: rescan the queue after an unlink

This patch (as1280) fixes an obscure bug in ehci-hcd's dequeuing logic
for async URBs.  If a later URB is unlinked and the completion
routine unlinks an earlier URB, then the earlier URB won't be given
back in a timely manner because the endpoint queue isn't rescanned as
it should be.

Similar bugs occur if an endpoint is reset or a halt is cleared while
a completion routine is running, because the subroutines don't test
for the COMPLETING state.

All these problems are solved by adding a new needs_rescan flag to the
ehci_qh structure.  If the flag is set while scanning through an idle
QH, the scan will be repeated.  If the QH isn't idle then an unlink
cycle will be initiated, and the proper action will be taken when it

Also, an unnecessary test is removed from qh_link_async(): That
routine is never called if the QH's state isn't IDLE.

Subject: USB: EHCI: change deschedule logic for interrupt QHs

This patch (as1281) changes the way ehci-hcd deschedules interrupt
QHs, copying the approach used for async QHs.  The caller is no longer
responsible for rescheduling the QH if its queue is non-empty; instead
the reschedule is done directly by intr_deschedule(), after calling
qh_completions().  This is exactly the same as how end_unlink_async()
works.

ehci_urb_dequeue() and intr_deschedule() now correctly handle the case
where they are called while another interrupt URB for the same QH is
being given back.  This was a surprisingly large blind spot.  And
scan_periodic() now respects the new needs_rescan flag.

Subject: USB: make usb_buffer_map_sg consistent with doc

usb_buffer_map_sg should return negative on error according to
its documentation. But dma_map_sg returns 0 on error. Take this
into account and return -ENOMEM in such situation.

While at it, return -EINVAL instead of -1 when wrong input is
passed in.

If this wasn't done, usb_sg_* operations used after usb_sg_init
which returned 0 may cause oopses/deadlocks since we don't init
structures/entries, esp. completion and status entry.

The documentation for usbmon in the kernel 2.6.31-rc7 kernel doesn't
match what the kernel exposes in the debug fs tree. This patch fixes it.

We set pdt_1f_for_no_lun for UFI devices, so most floppy entiries should
be unnecessary. This patch removes three entries which I'm certain are.
 - For Mitsumi I have a customer with RHEL 5 (bz#514296)
 - For SMSC I accessed Novell's Bugzilla and verified the entry
 - For Y-E I tested the patch with the actual device

Subject: USB: ehci,dbgp,early_printk: split ehci debug driver from
 early_printk.c

Move the dbgp early printk driver in advance of refactoring and adding
new code, so the changes to this code are tracked separately from the
move of the code.

The drivers/usb/early directory will be the location of the current
and future early usb code for driving usb devices prior initializing
the standard interrupt driven USB drivers.

Subject: USB: dbgp: insert cr prior to nl as needed

The rs232 drivers send a carriage return prior to a new line in the
early printk code.

The usb debug driver should do the same because you want to be able to
use the same terminal programs and tools for analysis of early printk
data.

The PCI quirk code executes a BIOS hand off to obtain full control of
the EHCI host controller, the self contained ehci-dbgp driver must do
the same thing using the early PCI API, else the BIOS can cause a
fatal fault.

Subject: USB: dbgp: EHCI debug controller initialization delays

When using the EHCI host controller as a polled device, a bit more
tolerance is required in terms of delays.  On some 3+ghz systems the
cpu loops were faster than the EHCI device mmio and resulted in the
controller failing to initialize.

On at least one first generation EHCI controller when it was not
operating in interrupt mode, it would fail to report a port change
status, but executing the port reset allowed the debug controller to
work correctly anyway.  This errata causes a one time 300ms delay in
the boot time, where as the typical delay is 1-5ms for an EHCI
controller that does not have this errata.

The debug printk's were fixed to have the correct state messages, and
there was a conversion from using early_printk to printk to avoid
calling the dbgp driver while debugging the initialization.

Subject: early_printk: Allow more than one early console

It is desirable to be able to use one early boot device to debug
another or to have multiple places you can see the early boot
diagnostics, such as the vga screen or serial device.

This patch changes the early_printk console device registration to
allow more than one early printk device to get registered via
register_console().

Subject: USB: ehci-dbgp: stability improvements and external re-init

This patch implements several changes:

1) Improve the capability to debug the dbgp driver

   The dbgp_ehci_status() was added in a number of places to report
   the critical ehci registers to diagnose the cause of a failure of
   the ehci-dbgp driver.

2) Capability to survive the host controller initialization

   The dbgp_external_startup(), dbgp_not_safe, and dbgp_phys_port were
   added so as to allow the ehci-dbgp to re-initialize after the ehci
   host controller is reset by the standard host controller driver.
   This same routine is common for the early startup or
   re-initialization.

   This resulted in the need to move some of the initialization code
   out of the __init section because the ehci driver has the
   possibility to be loaded later on as a kernel module.

3) Stability improvements for device initialization

   The device enumeration from 0 to 127 has the possibility to fail
   the first time after a warm reset on some older EHCI debug
   controllers.  The enumeration will be tried up to 3 times to
   account for this failure case.

   The dbg_wait_until_complete() was changed to wait up to 250 ms
   before failing which only comes into play during device
   initialization. The maximum delay will never get hit during the
   course of normal operation of the driver, unless the device got
   unplugged or there was a ehci controller failure, in which case the
   dbgp device driver will shut itself down.

Subject: USB: ehci-dbgp,ehci: Allow early or late use of the dbgp device

If the EHCI debug port is initialized and in use, the EHCI host
controller driver must follow two rules.

1) If the EHCI host driver issues a controller reset, the debug
   controller driver re-initialization must get called after the reset
   is completed.

2) The EHCI host driver should ignore any requests to the physical
   EHCI debug port when the EHCI debug port is in use.

The code to check for the debug port was moved from ehci_pci_reinit()
to ehci_pci_setup because it must get called prior to ehci_reset()
which will clear the debug port registers.

Subject: USB: ehci-dbgp: errata for EHCI debug controller initialization

On some EHCI usb debug controllers, the EHCI debug device will fail to
be seen after a port reset, after a warm reset.  Two options exist to
get the device to initialize correctly.

Option 1 is to unplug and plug in the device.

Option 2 is to use the EHCI port test to get the usb debug device to
start talking again.  At that point the debug controller port reset
will succeed.

Subject: USB: ehci-dbgp: errata for EHCI debug/host controller synchronization

On some EHCI debug controllers after the host controller driver is
activated, the debug controller will occasionally fail to submit a
bulk write URB.  On controllers that exhibit this behavior a dummy
bulk write must get submitted to resynchronize the device.

The "dummy bulk write" does not get received by the host attached to
the other end of the usb debug device.  The usb debug device simply
acknowledges the "dummy bulk write" and returns to a usable state.

The behavior, without this patch is that you see missing text from a
complete kernel boot when using the keep option to the earlyprintk
kernel argument.

Subject: USB: support for autosuspend in sierra while online

This implements support for autosuspend in the sierra driver while online.
Remote wakeup is used for reception. Transmission is facilitated with a queue
and the asynchronous autopm mechanism. To prevent races a private flag
for opened ports and a counter of running transmissions needs to be added.

Subject: USB: usbfs: add USBDEVFS_URB_BULK_CONTINUATION flag

This patch (as1283) adds a new flag, USBDEVFS_URB_BULK_CONTINUATION,
to usbfs.  It is intended for userspace libraries such as libusb and
openusb.  When they have to break up a single usbfs bulk transfer into
multiple URBs, they will set the flag on all but the first URB of the
series.

If an error other than an unlink occurs, the kernel will automatically
cancel all the following URBs for the same endpoint and refuse to
accept new submissions, until an URB is encountered that is not marked
as a BULK_CONTINUATION.  Such an URB would indicate the start of a new
transfer or the presence of an older library, so the kernel returns to
normal operation.

This enables libraries to delimit bulk transfers correctly, even in
the presence of early termination as indicated by short packets.

Subject: USB: xhci: Endpoint representation refactoring.

The xhci_ring structure contained information that is really related to an
endpoint, not a ring.  This will cause problems later when endpoint
streams are supported and there are multiple rings per endpoint.

Move the endpoint state and cancellation information into a new virtual
endpoint structure, xhci_virt_ep.  The list of TRBs to be cancelled should
be per endpoint, not per ring, for easy access.  There can be only one TRB
that the endpoint stopped on after a stop endpoint command (even with
streams enabled); move the stopped TRB information into the new virtual
endpoint structure.  Also move the 31 endpoint rings and temporary ring
storage from the virtual device structure (xhci_virt_device) into the
virtual endpoint structure (xhci_virt_ep).

Subject: USB: xhci: Refactor input device context setup.

Refactor common code to set up the add and drop flags for the input device
context setup.  This setup is used before a configure endpoint command for
the reset endpoint quirk, and will be used for the command to alloc or
free streams rings.

Subject: USB: xhci: Change how xHCI commands are handled.

Some commands to the xHCI hardware cannot be allowed to fail due to out of
memory issues or the command ring being full.

Add a way to reserve a TRB on the command ring, and make all command
queueing functions indicate whether they are using a reserved TRB.

Add a way to pre-allocate all the memory a command might need.  A command
needs an input context, a variable to store the status, and (optionally) a
completion for the caller to wait on.  Change all code that assumes the
input device context, status, and completion for a command is stored in
the xhci virtual USB device structure (xhci_virt_device).

Store pending completions in a FIFO in xhci_virt_device.  Make the event
handler for a configure endpoint command check to see whether a pending
command in the list has completed.  We need to use separate input device
contexts for some configure endpoint commands, since multiple drivers can
submit requests at the same time that require a configure endpoint
command.

Subject: USB: xhci: Fix command wait list handling.

In the xHCI driver, configure endpoint commands that are submitted to the
hardware may involve one of two data structures.  If the configure
endpoint command is setting up a new configuration or modifying max packet
sizes, the data structures and completions are statically allocated in the
xhci_virt_device structure.  If the command is being used to set up
streams or add hub information, then the data structures are dynamically
allocated, and placed on a device command waiting list.

Break out the code to check whether a completed command is in the device
command waiting list.  Fix a subtle bug in the old code: continue
processing the command if the command isn't in the wait list.  In the old
code, if there was a command in the wait list, but it didn't match the
completed command, the completed command event would be dropped.

Subject: USB: xhci: Set route string for all devices.

The xHCI driver needs to set the route string in the slot context of all
devices, not just SuperSpeed devices.  The route string concept was added
in the USB 3.0 specification, section 10.1.3.2.  Each hub in the topology
is expected to have no more than 15 ports in order for the route string of
a device to be unique.  SuperSpeed hubs are restricted to only having 15
ports, but FS/LS/HS hubs are not.  The xHCI specification says that if the
port number the device is under is greater than 15, that portion of the
route string shall be set to 15.

Subject: USB: xhci: Support USB hubs.

For a USB hub to work under an xHCI host controller, the xHC's internal
scheduler must be made aware of the hub's characteristics.  Add an xHCI
hook that the USB core will call after it fetches the hub descriptor.
This hook will add hub information to the slot context for that device,
including whether it has multiple TTs or a single TT, the number of ports
on the hub, and TT think time.

Setting up the slot context for the device is different for 0.95 and 0.96
xHCI host controllers.

Some of the slot context reserved fields in the 0.95 specification were
changed into hub fields in the 0.96 specification.  Don't set the TT think
time or number of ports for a hub if we're dealing with a 0.95-compliant
xHCI host controller.

The 0.95 xHCI specification says that to modify the hub flag, we need to
issue an evaluate context command.  The 0.96 specification says that flag
can be set with a configure endpoint command.  Issue the correct command
based on the version reported by the hardware.

This patch does not add support for multi-TT hubs.  Multi-TT hubs expose
a single TT on alt setting 0, and multi-TT on alt setting 1.  The xHCI
driver can't handle setting alternate interfaces yet.

Subject: USB: Add hub descriptor update hook for xHCI

Add a hook for updating xHCI internal structures after khubd fetches the
hub descriptor and sets up the hub's TT information.  The xHCI driver must
update the internal structures before devices under the hub can be
enumerated.

Subject: USB: skel_read really sucks royally

The read code path of the skeleton driver really sucks

 - skel_read works only for devices which always send data
 - the timeout comes out of thin air
 - it blocks signals for the duration of the timeout
 - it disallows nonblocking IO by design

This patch fixes it by using a real urb, a completion and interruptible waits.

Subject: USB: O_NONBLOCK in read path of skeleton

Non blocking IO is supported in the read path of usb-skeleton.
This is done by just not blocking. As support for handling signals
without stopping IO is already there, it can be used for O_NONBLOCK, too.

Subject: ecryptfs: Remove unneeded locking that triggers lockdep false
 positives

In ecryptfs_destroy_inode(), inode_info->lower_file_mutex is locked,
and just after the mutex is unlocked, the code does:

 	kmem_cache_free(ecryptfs_inode_info_cache, inode_info);

This means that if another context could possibly try to take the same
mutex as ecryptfs_destroy_inode(), then it could end up getting the
mutex just before the data structure containing the mutex is freed.
So any such use would be an obvious use-after-free bug (catchable with
slab poisoning or mutex debugging), and therefore the locking in
ecryptfs_destroy_inode() is not needed and can be dropped.

Similarly, in ecryptfs_destroy_crypt_stat(), crypt_stat->keysig_list_mutex
is locked, and then the mutex is unlocked just before the code does:

 	memset(crypt_stat, 0, sizeof(struct ecryptfs_crypt_stat));

Therefore taking this mutex is similarly not necessary.

Removing this locking fixes false-positive lockdep reports such as the
following (and they are false-positives for exactly the same reason
that the locking is not needed):

Subject: eCryptfs: Fix lockdep-reported AB-BA mutex issue

Lockdep reports the following valid-looking possible AB-BA deadlock with
global_auth_tok_list_mutex and keysig_list_mutex:

  ecryptfs_new_file_context() ->
      ecryptfs_copy_mount_wide_sigs_to_inode_sigs() ->
          mutex_lock(&mount_crypt_stat->global_auth_tok_list_mutex);
          -> ecryptfs_add_keysig() ->
              mutex_lock(&crypt_stat->keysig_list_mutex);

vs

  ecryptfs_generate_key_packet_set() ->
      mutex_lock(&crypt_stat->keysig_list_mutex);
      -> ecryptfs_find_global_auth_tok_for_sig() ->
          mutex_lock(&mount_crypt_stat->global_auth_tok_list_mutex);

ie the two mutexes are taken in opposite orders in the two different
code paths.  I'm not sure if this is a real bug where two threads could
actually hit the two paths in parallel and deadlock, but it at least
makes lockdep impossible to use with ecryptfs since this report triggers
every time and disables future lockdep reporting.

Since ecryptfs_add_keysig() is called only from the single callsite in
ecryptfs_copy_mount_wide_sigs_to_inode_sigs(), the simplest fix seems to
be to move the lock of keysig_list_mutex back up outside of the where
global_auth_tok_list_mutex is taken.  This patch does that, and fixes
the lockdep report on my system (and ecryptfs still works OK).

The full output of lockdep fixed by this patch is:

Subject: ecryptfs: improved dependency checking and reporting

So, I compiled a 2.6.31-rc5 kernel with ecryptfs and loaded its module.
When it came time to mount my filesystem, I got this in dmesg, and it
refused to mount:

[93577.776637] Unable to allocate crypto cipher with name [aes]; rc = [-2]
[93577.783280] Error attempting to initialize key TFM cipher with name = [aes]; rc = [-2]
[93577.791183] Error attempting to initialize cipher with name = [aes] and key size = [32]; rc = [-2]
[93577.800113] Error parsing options; rc = [-22]

I figured from the error message that I'd either forgotten to load "aes"
or that my key size was bogus.  Neither one of those was the case.  In
fact, I was missing the CRYPTO_ECB config option and the 'ecb' module.
Unfortunately, there's no trace of 'ecb' in that error message.

I've done two things to fix this.  First, I've modified ecryptfs's
Kconfig entry to select CRYPTO_ECB and CRYPTO_CBC.  I also took CRYPTO
out of the dependencies since the 'select' will take care of it for us.

I've also modified the error messages to print a string that should
contain both 'ecb' and 'aes' in my error case.  That will give any
future users a chance of finding the right modules and Kconfig options.

I also wonder if we should:

	select CRYPTO_AES if !EMBEDDED

since I think most ecryptfs users are using AES like me.

Returns an error when an unrecognized cipher code is present in a tag 3

crypt_stat->tfm error pointer to NULL to ensure that it will not be
incorrectly freed in ecryptfs_destroy_crypt_stat().

Subject: eCryptfs: Check for O_RDONLY lower inodes when opening lower files

If the lower inode is read-only, don't attempt to open the lower file
read/write and don't hand off the open request to the privileged
eCryptfs kthread for opening it read/write.  Instead, only try an
unprivileged, read-only open of the file and give up if that fails.
This patch fixes an oops when eCryptfs is mounted on top of a read-only
mount.

Subject: eCryptfs: Filename encryption only supports password auth tokens

Returns -ENOTSUPP when attempting to use filename encryption with
something other than a password authentication token, such as a private
token from openssl.  Using filename encryption with a userspace eCryptfs
key module is a future goal.  Until then, this patch handles the
situation a little better than simply using a BUG_ON().

Subject: eCryptfs: Propagate vfs_read and vfs_write return codes

Errors returned from vfs_read() and vfs_write() calls to the lower
filesystem were being masked as -EINVAL.  This caused some confusion to
users who saw EINVAL instead of ENOSPC when the disk was full, for
instance.

Also, the actual bytes read or written were not accessible by callers to
ecryptfs_read_lower() and ecryptfs_write_lower(), which may be useful in
some cases.  This patch updates the error handling logic where those
functions are called in order to accept positive return codes indicating
success.

Subject: eCryptfs: Prevent lower dentry from going negative during unlink
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When calling vfs_unlink() on the lower dentry, d_delete() turns the
dentry into a negative dentry when the d_count is 1.  This eventually
caused a NULL pointer deref when a read() or write() was done and the
negative dentry's d_inode was dereferenced in
ecryptfs_read_update_atime() or ecryptfs_getxattr().

Placing mutt's tmpdir in an eCryptfs mount is what initially triggered
the oops and I was able to reproduce it with the following sequence:

open("/tmp/upper/foo", O_RDWR|O_CREAT|O_EXCL|O_NOFOLLOW, 0600) = 3
link("/tmp/upper/foo", "/tmp/upper/bar") = 0
unlink("/tmp/upper/foo")                = 0
open("/tmp/upper/bar", O_RDWR|O_CREAT|O_NOFOLLOW, 0600) = 4
unlink("/tmp/upper/bar")                = 0
write(4, "eCryptfs test\n"..., 14 <unfinished ...>

Subject: poll/select: avoid arithmetic overflow in __estimate_accuracy()

__estimate_accuracy() was prone to integer overflow, for example if *tv ==
{2147, 483648000} on a 32 bit computer (or even for delays as small as
{429, 500000000} if the task is niced).

Because the result was already forced between 0 and 100ms, the effect of
the overflow was not too problematic, but the use of the hrtimer range
feature was not optimal in overflow cases.

This patch ensures that there can not be an integer overflow in this
function.

Subject: printk: add printk_delay to make messages readable for some scenarios

When syslog is not possible, at the same time there's no serial/net
console available, it will be hard to read the printk messages.  For
example oops/panic/warning messages in shutdown phase.

Add a printk delay feature, we can make each printk message delay some
milliseconds.

Setting the delay by proc/sysctl interface: /proc/sys/kernel/printk_delay

The value range from 0 - 10000, default value is 0

Subject: kmod: fix race in usermodehelper code

The user mode helper code has a race in it.  call_usermodehelper_exec()
takes an allocated subprocess_info structure, which it passes to a
workqueue, and then passes it to a kernel thread which it creates, after
which it calls complete to signal to the caller of
call_usermodehelper_exec() that it can free the subprocess_info struct.

But since we use that structure in the created thread, we can't call
complete from __call_usermodehelper(), which is where we create the kernel
thread.  We need to call complete() from within the kernel thread and then
not use subprocess_info afterward in the case of UMH_WAIT_EXEC.  Tested
successfully by me.

Subject: generic-ipi: make struct call_function_data lockless

This patch can remove spinlock from struct call_function_data, the
reasons are below:

1: add a new interface for cpumask named cpumask_test_and_clear_cpu(),
   it can atomically test and clear specific cpu, we can use it instead
   of cpumask_test_cpu() and cpumask_clear_cpu() and no need data->lock
   to protect those in generic_smp_call_function_interrupt().

2: in smp_call_function_many(), after csd_lock() return, the current's
   cfd_data is deleted from call_function list, so it not have race
   between other cpus, then cfs_data is only used in
   smp_call_function_many() that must disable preemption and not from
   a hardware interrupthandler or from a bottom half handler to call,
   only the correspond cpu can use it, so it not have race in current
   cpu, no need cfs_data->lock to protect it.

3: after 1 and 2, cfs_data->lock is only use to protect cfs_data->refs in
   generic_smp_call_function_interrupt(), so we can define cfs_data->refs
   to atomic_t, and no need cfs_data->lock any more.

Subject: dme1737: Keep index within pwm_config[]

The static code scanner "Parfait" reported this because pwm_config is
only 3 bytes - pwm_config[3] is out of range.

Since this code path is never called with ix == 3 (the device has no PWM4
output) this doesn't change anything in practice.  But to encourage
testing with Parfait, lets make the warning go away...

From 88e9d34c727883d7d6f02cf1475b3ec98b8480c7 Mon Sep 17 00:00:00 2001
From: James Morris <jmorris@namei.org>
Date: Tue, 22 Sep 2009 16:43:43 -0700
Subject: seq_file: constify seq_operations

Make all seq_operations structs const, to help mitigate against
revectoring user-triggerable function pointers.

This is derived from the grsecurity patch, although generated from scratch
because it's simpler than extracting the changes from there.

Subject: proc connector: add event for process becoming session leader

The act of a process becoming a session leader is a useful signal to a
supervising init daemon such as Upstart.

While a daemon will normally do this as part of the process of becoming a
daemon, it is rare for its children to do so.  When the children do, it is
nearly always a sign that the child should be considered detached from the
parent and not supervised along with it.

The poster-child example is OpenSSH; the per-login children call setsid()
so that they may control the pty connected to them.  If the primary daemon
dies or is restarted, we do not want to consider the per-login children
and want to respawn the primary daemon without killing the children.

This patch adds a new PROC_SID_EVENT and associated structure to the
proc_event event_data union, it arranges for this to be emitted when the
special PIDTYPE_SID pid is set.

Subject: printk_once(): use bool for boolean flag

Using the type bool (instead of int) for the __print_once flag in the
printk_once() macro matches the intent of the code better, and allows the
compiler to generate smaller code; eg a typical callsite with gcc 4.3.3 on
i386:

add/remove: 0/0 grow/shrink: 0/2 up/down: 0/-6 (-6)
function                                     old     new   delta
static.__print_once                            4       1      -3
get_cpu_vendor                               146     143      -3

Saving 6 bytes of object size per callsite by slightly improving the
readability of the source seems like a win to me.

Subject: fs: turn iprune_mutex into rwsem

We have had a report of bad memory allocation latency during DVD-RAM (UDF)
writing.  This is causing the user's desktop session to become unusable.

Jan tracked the cause of this down to UDF inode reclaim blocking:

Now I think the main problem is having the filesystem block (and do IO) in
inode reclaim.  The problem is that this doesn't get accounted well and
penalizes a random allocator with a big latency spike caused by work
generated from elsewhere.

I think the best idea would be to avoid this.  By design if possible, or
by deferring the hard work to an asynchronous context.  If the latter,
then the fs would probably want to throttle creation of new work with
queue size of the deferred work, but let's not get into those details.

Anyway, the other obvious thing we looked at is the iprune_mutex which is
causing the cascading blocking.  We could turn this into an rwsem to
improve concurrency.  It is unreasonable to totally ban all potentially
slow or blocking operations in inode reclaim, so I think this is a cheap
way to get a small improvement.

This doesn't solve the whole problem of course.  The process doing inode
reclaim will still take the latency hit, and concurrent processes may end
up contending on filesystem locks.  So fs developers should keep these
problems in mind.

Subject: fs/buffer.c: clean up EXPORT* macros

According to Documentation/CodingStyle the EXPORT* macro should follow
immediately after the closing function brace line.

Also, mark_buffer_async_write_endio() and do_thaw_all() are not used
elsewhere so they should be marked as static.

In addition, file_fsync() is actually in fs/sync.c so move the EXPORT* to
that file.

Subject: BUILD_BUG_ON(): fix it and a couple of bogus uses of it

gcc permitting variable length arrays makes the current construct used for
BUILD_BUG_ON() useless, as that doesn't produce any diagnostic if the
controlling expression isn't really constant.  Instead, this patch makes
it so that a bit field gets used here.  Consequently, those uses where the
condition isn't really constant now also need fixing.

Note that in the gfp.h, kmemcheck.h, and virtio_config.h cases
MAYBE_BUILD_BUG_ON() really just serves documentation purposes - even if
the expression is compile time constant (__builtin_constant_p() yields
true), the array is still deemed of variable length by gcc, and hence the
whole expression doesn't have the intended effect.

Subject: aio.c: move EXPORT* macros to line after function

As mentioned in Documentation/CodingStyle, move EXPORT* macro's
to the line immediately after the closing function brace line.

Also, move the __initcall() similarly.

Subject: anonfd: split interface into file creation and install

Split the anonfd interface into a bare file pointer creation one, and a
file pointer creation plus install one.

There are cases, like the usage of eventfds inside other kernel
interfaces, where the file pointer created by anonfd needs to be used
inside the initialization of other structures.

As it is right now, as soon as anon_inode_getfd() returns, the kenrle can
race with userspace closing the newly installed file descriptor.

This patch, while keeping the old anon_inode_getfd(), introduces a new
anon_inode_getfile() (whose services are reused in anon_inode_getfd())
that allows to split the file creation phase and the fd install one.

Once all the kernel structures are initialized, the code can call the
proper fd_install().

Gregory manifested the need for something like this inside KVM.

Subject: qnx4: remove write support

qnx4 wrte support has never been fully implement, is broken since the dawn
of time and hasn't been actively developed since before git history
started.

Instead of letting it further bitrot and complicate API transition (like
the new truncate code) remove it.

Subject: fix compat_sys_utimensat()

Compat utimensat() returns EINVAL when the tv_nsec is one of UTIME_OMIT or
UTIME_NOW and the tv_sec is set to non-zero.  As per man pages, the tv_sec
field should be ignored.

sys_utimensat() works fine in this case.

Test case:

#define _GNU_SOURCE
#define _ATFILE_SOURCE
#include <stdio.h>
#include <fcntl.h>
#include <unistd.h>
#include <sys/stat.h>
#include <stdlib.h>

main(int argc, char *argv[])
{
	struct timespec ts[2];
	struct timespec *tsp;

	if (argc < 2) {
		fprintf(stderr, "Usage : %s filename\n", argv[0]);
		exit (-1);
	}

	ts[0].tv_nsec = ts[1].tv_nsec = UTIME_NOW;
	ts[0].tv_sec = ts[1].tv_sec = 1;

	tsp = ts;

	if (utimensat(AT_FDCWD, argv[1],tsp,0) == -1)
		perror("utimensat");
	else
		fprintf(stdout, "utimensat success\n");
	return 0;
}

Subject: Make sure the value in abs() does not get truncated if it is greater
 than 2^32

abs() will truncate the input if is it outside the 2^32 range.  Fix that
by assuming `long' input.

This might generate worse code in the common case.

Subject: kmap_types.h: rename D macro

I tend to use a 'D' debugging macro a lot during debugging.  When I define
it before includes I often get conflicts with kmap_types.h's use of 'D'
too.  It's not very nice when a global include pollutes the name space
like this.

Rename the kmap_types.h D to KMAP_D.  It is only used temporarily in the
header so has no effect on anything else.

Subject: getrusage: fill ru_maxrss value

Make ->ru_maxrss value in struct rusage filled accordingly to rss hiwater
mark.  This struct is filled as a parameter to getrusage syscall.
->ru_maxrss value is set to KBs which is the way it is done in BSD
systems.  /usr/bin/time (gnu time) application converts ->ru_maxrss to KBs
which seems to be incorrect behavior.  Maintainer of this util was
notified by me with the patch which corrects it and cc'ed.

To make this happen we extend struct signal_struct by two fields.  The
first one is ->maxrss which we use to store rss hiwater of the task.  The
second one is ->cmaxrss which we use to store highest rss hiwater of all
task childs.  These values are used in k_getrusage() to actually fill
->ru_maxrss.  k_getrusage() uses current rss hiwater value directly if mm
struct exists.

Note:
exec() clear mm->hiwater_rss, but doesn't clear sig->maxrss.
it is intetionally behavior. *BSD getrusage have exec() inheriting.

Subject: kallsyms: fix segfault in prefix_underscores_count()

Commit b478b782e110fdb4135caa3062b6d687e989d994 "kallsyms, tracing: output
more proper symbol name" introduces a "bugfix" that introduces a segfault
in kallsyms in my configurations.

The cause is the introduction of prefix_underscores_count() which attempts
to count underscores, even in symbols that do not have them.  As a result,
it just uselessly runs past the end of the buffer until it crashes:

  CC      init/version.o
  LD      init/built-in.o
  LD      .tmp_vmlinux1
  KSYM    .tmp_kallsyms1.S
/bin/sh: line 1: 16934 Done                    sh-linux-gnu-nm -n .tmp_vmlinux1
     16935 Segmentation fault      | scripts/kallsyms > .tmp_kallsyms1.S
make: *** [.tmp_kallsyms1.S] Error 139

This simplifies the logic and just does a straightforward count.

Subject: asm/sections: add text/data checking functions for arches to override

Some ports (like the Blackfin arch) have a discontiguous memory map which
means there may be text or data that falls outside of the standard range
of the start/end text/data symbols.  Creating some helper functions allows
these non-standard ports to declare these regions without adversely
affecting anyone else.

Subject: mmc: register mmci-omap-hs using platform_driver_probe
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

omap_mmc_probe lives in .init.text, so using platform_driver_register to
register it is wrong because binding a device after the init memory is
discarded (e.g.  via sysfs) results in an oops.

As requested by David Brownell platform_driver_probe is used instead of
moving the probe function to .devinit.text as proposed initially.  This
saves some memory, but devices registered after the driver is probed are
not bound (probably there are none) and binding via sysfs isn't possible.

Subject: mmc: add 'enable' and 'disable' methods to mmc host

MMC hosts that support power saving can use the 'enable' and 'disable'
methods to exit and enter power saving states.  An explanation of their
use is provided in the comments added to include/linux/mmc/host.h.

This change allows the MMC host to be claimed in situations where the host
may or may not have already been claimed.  Also 'mmc_try_claim_host()' is
now exported.

Subject: mmc: add MMC_CAP_NONREMOVABLE host capability

eMMC's are not removable, so unsafe resume is OK always.

To permit this a new host capability MMC_CAP_NONREMOVABLE has been added
and suspend / resume updated accordingly.

Subject: mmc: add ability to save power by powering off cards

Power can be saved by powering off cards that are not in use.  This is
similar to suspend / resume except it is under the control of the driver,
and does not require any power management support.  It can only be used
when the driver can monitor whether the card is removed, otherwise it is
unsafe.  This is possible because, unlike suspend, the driver still
receives card detect and / or cover switch interrupts.

Subject: ARM: OMAP: mmc-twl4030: add context loss counter support

PM dynamic OFF state results in context loss.  That is, the host
controller has been powered off at some point, which means the registers
have been reset.  The driver must detect when this happens, and restore
the context.  This patch adds the means to detect context loss.

Note, the PM side is not yet implemented.

Subject: omap_hsmmc: keep track of power mode

This patch is preparation for adding context save and restore support.

Keep track of the current power mode so that the context restore function
can avoid restoring the context for a card if the power has been switched
off.  If the power is off, the card must be reinitialized anyway which
will re-establish the context.

Subject: omap_hsmmc: put MMC regulator to sleep

When a card is not in use, the voltage regulator can be put to sleep.
This is an alternative to powering the card off, when powering off is not
safe because the card might be replaced without the driver being aware of
it.

That situation happens if:
	- the card is removable i.e. not eMMC
	- and there is no card detect
	- and there is a cover switch but the cover is open

Subject: omap_hsmmc: cater for weird CMD6 behaviour

Sometimes the controller unexpectedly produces a TC (transfer complete)
interrupt before the CC (command complete) interrupt for command 6
(SWITCH).  This is a problem because the CC interrupt can get mixed up
with the next request.  Add a hack for CMD6.

Subject: omap_hsmmc: prevent races with irq handler

If an unexpected interrupt occurs while preparing the next request, an
oops can occur.

For example, a new request is setting up DMA for data transfer so
host->data is not NULL.  An unexpected transfer complete (TC) interrupt
comes along and the interrupt handler sets host->data to NULL.  Oops!

Prevent that by adding a spinlock.

Subject: omap_hsmmc: protect the card when the cover is open

Depending on the manufacturer, there is a small possibility that removing
a card while it is being written to, can render the card permanently
unusable.  To prevent that, the card is made inaccessible when the cover
is open.

Subject: omap_hsmmc: set a large data timeout for commands with busy signal

Commands like SWITCH (CMD6) send a response and then signal busy while the
operation is completed.  These commands are expected to always succeed
(otherwise the response would have indicated an error).

Set an arbitrarily large data timeout value (100ms) for these commands to
ensure that premature timeouts do not occur.

Subject: sdio: add CD disable support

Add support to disconnect the pull-up resistor on CD/DAT[3] (pin 1)
of the card. This may be desired on certain setups of boards,
controllers and embedded sdio devices which do not need the card's
pull-up. As a result, card detection is disabled and power is saved.

Subject: sdhci: be more strict with get_min_clock() usage

get_min_clock() makes sense only with NONSTANDARD_CLOCK quirk and when
set_clock() callback is specified.

The patch should cause no functional changes, it just makes the code
self-documented and avoids any possible misuse of get_min_clock().

Linear divisor's values in a register start at 0 (zero means "divide by
1").  Before this patch the code didn't account that fact, so SD cards
were running underclocked.

Subject: sdhci-of: avoid writing reserved bits into host control register

SDHCI core tries to write HISPD bit into the host control register, but
the eSDHC controllers don't have that bit, and that causes all sorts of
misbehaviour when using 4-bit mode capable SD cards.

Subject: sdhci-of: fix high-speed cards recognition

eSDHC fails to recognize some SDHS cards, throwing timeout errors:

  mmc0: error -110 whilst initialising SD card

That's because we calculate timeout value in a wrong way: on eSDHC hosts
the timeout clock is derivied from the SD clock, which is set dynamically.

As David Vrabel suggested, deriving timeout clock from SD clock is a
common scheme, so let's implement DATA_TIMEOUT_USES_SDCLK quirk and use it
for eSDHC hosts.

Also, from now on we don't need esdhc_get_timeout_clock() callback, so
remove it.

Subject: sdhci-of: don't hard-code inverted write-protect quirk

MPC85xx SOCs have normal write-protect state reporting, so we shouldn't
hard-code the quirk.

Instead, look for "sdhci,wp-inverted" property, plus check for
mpc837x_{rdb,mds} machines since older device trees don't specify the new
property.

Subject: sdhci-of: cleanup eSDHC's set_clock() a little bit

- Get rid of incomprehensible "if { for { if } }" construction for the
  exponential divisor calculation. The first if statement isn't correct
  at all, since it should check for "host->max_clk / pre_div / 16 >
  clock". The error doesn't cause any bugs because the check in the for
  loop does the right thing, and so the outer check becomes useless;

- For the linear divisor do the same: a single while statement is more
  readable than for + if construction;

- Add dev_dbg() that prints desired and actual clock frequency.

Subject: sdio: add MMC_QUIRK_LENIENT_FN0

Normally writes to SDIO function 0 outside the vendor specific CCCR
registers are prohibited.

To support embedded devices that require writes to SDIO function 0 outside
this range (e.g.  TI WL127x embedded sdio wifi device),
MMC_QUIRK_LENIENT_FN0 is introduced.

A card quirks field is added to `struct mmc_card' to support non-standard
devices (e.g.  embedded sdio devices).

Subject: atmel-mci: unified Atmel MCI drivers (AVR32 & AT91)

Unification of the atmel-mci driver to support the AT91 processors MCI
interface.  The atmel-mci driver currently supports the AVR32 and this
patch adds AT91 support.

Add read/write proof selection switch dependent on chip availability of
this feature.

To use this new driver on a at91 the platform driver for your board needs
to be updated.

Subject: AT91: atmel-mci: Platform configuration to the the atmel-mci driver

Created a modified version of the at91sam9g20 evaluation kit platform
(board-sam9g20ek-2slot-mmc.c) and device support to make use of the
updated atmel-mci driver.

As the use of two slots modify GPIO pin allocation, we create another
board file.

This requires getting the most updated arch/arm/tools/mach-types from
http://www.arm.linux.org.uk/developer/machines/download.php to have the machine
type for the at91sam9g20ek-2slot-mmc board.

Subject: mmc_spi: fail gracefully if host or card do not support the switch
 command

Some time ago, I have send a patch to the mmc_spi subsystem changing the
error codes.  This was after a discussion with Pierre about using EINVAL
only for non-recoverable errors.  This patch was accepted as

http://git.kernel.org/linus/fdd858db7113ca64132de390188d7ca00701013d

Unfortunately, several weeks later, I realized that this patch has opened
a little can of worms because there are SD cards on the market which

a) claim that they support the switch command
AND
b) refuse to execute this command if operating in SPI mode.

So, such a card would get unusuable in an embedded linux system in SPI
mode, because the init sequence terminates with an error.

This patch adds the missing error codes to the caller of the switch
command and restores the old behaviour to fail gracefully if these
commands can not execute.

Subject: mmc: core SDIO suspend/resume support

Currently, all SDIO cards are virtually removed upon a suspend, and
completely reprobed upon a resume.  This adds the suspend and resume
methods to the SDIO bus driver so to be able to dispatch those events to
the actual SDIO function drivers for real suspend/resume instead.

All active functions on a card must have a driver with both a suspend and
a resume method though.  Failing that, we fall back to the current
behavior of simply "removing" the card when suspending.

When resuming, we make sure the same card is still inserted by comparing
the vendor and product IDs.  If there is a mismatch, or if there is simply
no card anymore in the slot, then the previous card is "removed" and the
new card is detected.  This is further enhanced with the next patch.

Subject: mmc: propagate error codes back from bus drivers' suspend/resume
 methods

Especially for SDIO drivers which may have special conditions/errors to
report, it is a good thing to relay the returned error code back to upper
layers.

This also allows for the rationalization of the resume path where code to
"remove" a no-longer-existing or replaced card was duplicated into the
MMC, SD and SDIO bus drivers.

In the SDIO case, if a function suspend method returns an error, then all
previously suspended functions are resumed and the error returned.  An
exception is made for -ENOSYS which the core interprets as "we don't
support suspend so just kick the card out for suspend and return success".

When resuming SDIO cards, the core code only validates the manufacturer
and product IDs to make sure the same kind of card is still present before
invoking functions resume methods.  It's the function driver's
responsibility to perform further tests to confirm that the actual same
card is present (same MAC address, etc.) and return an error otherwise.

Subject: sdhci: increase timeout for internal clock stabilization.

On an OLPC XO-1.5 development board with Via VX855 chipset, the sdhci
controller can take up to 12ms to stabilize its clock, but the current
timeout at which we give up on the controller is 10ms.

The patch increases the timeout delay rather than using a device-specific
quirk -- since we exit the loop when the clock comes up, increasing the
timeout value will only make us mdelay() longer in the errant case of a
device with a clock that is not stabilizing, which it seems worth waiting
a little longer for in general.

Subject: proc_flush_task: flush /proc/tid/task/pid when a sub-thread exits

The exiting sub-thread flushes /proc/pid only, but this doesn't buy too
much: ps and friends mostly use /proc/tid/task/pid.

Remove "if (thread_group_leader())" checks from proc_flush_task() path,
this means we always remove /proc/tid/task/pid dentry on exit, and this
actually matches the comment above proc_flush_task().

The test-case:

	static void* tfunc(void *arg)
	{
		char name[256];

		sprintf(name, "/proc/%d/task/%ld/status", getpid(), gettid());
		close(open(name, O_RDONLY));

		return NULL;
	}

	int main(void)
	{
		pthread_t t;

		for (;;) {
			if (!pthread_create(&t, NULL, &tfunc, NULL))
				pthread_join(t, NULL);
		}
	}

slabtop shows that pid/proc_inode_cache/etc grow quickly and
"indefinitely" until the task is killed or shrink_slab() is called, not
good.  And the main thread needs a lot of time to exit.

The same can happen if something like "ps -efL" runs continuously, while
some application spawns short-living threads.

Subject: fs/proc/task_mmu.c v1: fix clear_refs_write() input sanity check

Andrew Morton pointed out similar string hacking and obfuscated check for
zero-length input at the end of the function, David Rientjes suggested to
use strict_strtol to replace simple_strtol, this patch cover above
suggestions, add removing of leading and trailing whitespace from user
input.  It does not change function behavious.

Subject: fs/proc/base.c: fix proc_fault_inject_write() input sanity check

Remove obfuscated zero-length input check and return -EINVAL instead of
-EIO error to make the error message clear to user.  Add whitespace
stripping.  No functionality changes.

The old code:

echo  1  > /proc/pid/make-it-fail (ok)
echo 1foo > /proc/pid/make-it-fail (-bash: echo: write error: Input/output error)

The new code:

echo  1  > /proc/pid/make-it-fail (ok)
echo 1foo > /proc/pid/make-it-fail (-bash: echo: write error: Invalid argument)

This patch is conservative in changes to not breaking existing
scripts/applications.

Subject: procfs: provide stack information for threads

A patch to give a better overview of the userland application stack usage,
especially for embedded linux.

Currently you are only able to dump the main process/thread stack usage
which is showed in /proc/pid/status by the "VmStk" Value.  But you get no
information about the consumed stack memory of the the threads.

There is an enhancement in the /proc/<pid>/{task/*,}/*maps and which marks
the vm mapping where the thread stack pointer reside with "[thread stack
xxxxxxxx]".  xxxxxxxx is the maximum size of stack.  This is a value
information, because libpthread doesn't set the start of the stack to the
top of the mapped area, depending of the pthread usage.

A sample output of /proc/<pid>/task/<tid>/maps looks like:

08048000-08049000 r-xp 00000000 03:00 8312       /opt/z
08049000-0804a000 rw-p 00001000 03:00 8312       /opt/z

ffffe000-fffff000 r-xp 00000000 00:00 0          [vdso]

Also there is a new entry "stack usage" in /proc/<pid>/{task/*,}/status
which will you give the current stack usage in kb.

A sample output of /proc/self/status looks like:

Name:	cat
State:	R (running)
Tgid:	507
Pid:	507
.
.
.
CapBnd:	fffffffffffffeff
voluntary_ctxt_switches:	0
nonvoluntary_ctxt_switches:	0
Stack usage:	12 kB

I also fixed stack base address in /proc/<pid>/{task/*,}/stat to the base
address of the associated thread stack and not the one of the main
process.  This makes more sense.

Subject: kcore: use usual list for kclist

This patchset is for /proc/kcore.  With this,

 - many per-arch hooks are removed.

 - /proc/kcore will know really valid physical memory area.

 - /proc/kcore will be aware of memory hotplug.

 - /proc/kcore will be architecture independent i.e.
   if an arch supports CONFIG_MMU, it can use /proc/kcore.
   (if the arch uses usual memory layout.)

This patch:

/proc/kcore uses its own list handling codes. It's better to use
generic list codes.

No changes in logic. just clean up.

Subject: kcore: add kclist types

Presently, kclist_add() only eats start address and size as its arguments.
Considering to make kclist dynamically reconfigulable, it's necessary to
know which kclists are for System RAM and which are not.

This patch add kclist types as
  KCORE_RAM
  KCORE_VMALLOC
  KCORE_TEXT
  KCORE_OTHER

This "type" is used in a patch following this for detecting KCORE_RAM.

Subject: kcore: register vmalloc area in generic way

For /proc/kcore, vmalloc areas are registered per arch.  But, all of them
registers same range of [VMALLOC_START...VMALLOC_END) This patch unifies
them.  By this.  archs which have no kclist_add() hooks can see vmalloc
area correctly.

Subject: kcore: register text area in generic way

Some 64bit arch has special segment for mapping kernel text.  It should be
entried to /proc/kcore in addtion to direct-linear-map, vmalloc area.
This patch unifies KCORE_TEXT entry scattered under x86 and ia64.

I'm not familiar with other archs (mips has its own even after this patch)
but range of [_stext ..._end) is a valid area of text and it's not in
direct-map area, defining CONFIG_ARCH_PROC_KCORE_TEXT is only a necessary
thing to do.

Note: I left mips as it is now.

Subject: walk system ram range
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Originally, walk_memory_resource() was introduced to traverse all memory
of "System RAM" for detecting memory hotplug/unplug range.  For doing so,
flags of IORESOUCE_MEM|IORESOURCE_BUSY was used and this was enough for
memory hotplug.

But for using other purpose, /proc/kcore, this may includes some firmware
area marked as IORESOURCE_BUSY | IORESOUCE_MEM.  This patch makes the
check strict to find out busy "System RAM".

Note: PPC64 keeps their own walk_memory_resouce(), which walk through
ppc64's lmb informaton.  Because old kclist_add() is called per lmb, this
patch makes no difference in behavior, finally.

And this patch removes CONFIG_MEMORY_HOTPLUG check from this function.
Because pfn_valid() just show "there is memmap or not* and cannot be used
for "there is physical memory or not", this function is useful in generic
to scan physical memory range.

Subject: kcore: use registerd physmem information

For /proc/kcore, each arch registers its memory range by kclist_add().
In usual,

	- range of physical memory
	- range of vmalloc area
	- text, etc...

are registered but "range of physical memory" has some troubles.  It
doesn't updated at memory hotplug and it tend to include unnecessary
memory holes.  Now, /proc/iomem (kernel/resource.c) includes required
physical memory range information and it's properly updated at memory
hotplug.  Then, it's good to avoid using its own code(duplicating
information) and to rebuild kclist for physical memory based on
/proc/iomem.

Subject: kcore: register vmemmap range

Benjamin Herrenschmidt <benh@kernel.crashing.org> pointed out that vmemmap
range is not included in KCORE_RAM, KCORE_VMALLOC ....

This adds KCORE_VMEMMAP if SPARSEMEM_VMEMMAP is used.  By this, vmemmap
can be readable via /proc/kcore

Because it's not vmalloc area, vread/vwrite cannot be used.  But the range
is static against the memory layout, this patch handles vmemmap area by
the same scheme with physical memory.

This patch assumes SPARSEMEM_VMEMMAP range is not in VMALLOC range.  It's
correct now.

Subject: kcore: register module area in generic way

Some archs define MODULED_VADDR/MODULES_END which is not in VMALLOC area.
This is handled only in x86-64.  This patch make it more generic.  And we
can use vread/vwrite to access the area.  Fix it.

Subject: /proc/kcore: fix stat.st_size

Presently the size of /proc/kcore which can be read by 'ls -l' is 0.  But
it's not the correct value.

On x86-64, ls -l shows
 ... root root 140737486266368 2009-09-17 10:29 /proc/kcore
Then, 7FFFFFFE02000. This comes from vmalloc area's size.
(*) This shows "core" size, not  memory size.

This patch shows the size by updating "size" field in struct
proc_dir_entry.  Later, lookup routine will create inode and fill
inode->i_size based on this value.  Then, this has a problem.

 - Once inode is cached, inode->i_size will never be updated.

Then, this patch is not memory-hotplug-aware.

To update inode->i_size, we have to know dentry or inode.
But there is no way to lookup them by inside kernel. Hmmm....
Next patch will try it.

Subject: /proc/kcore: update stat.st_size after memory hotplug

After memory hotplug (or other events in future), kcore size can be
modified.

To update inode->i_size, we have to know inode/dentry but we can't get it
from inside /proc directly.  But considerinyg memory hotplug, kcore image
is updated only when it's opened.  Then, updating inode->i_size at open()
is enough.

This makes the PL022 driver a default choice for any RealView and
Versatile boards plus the integrator IMPD1 which all contain the PL022
PrimeCell.  This will make it a default choice if and only if a user
selects SPI support for their board.

Subject: spi: add support for device table matching

With this patch spi drivers can use standard spi_driver.id_table and
MODULE_DEVICE_TABLE() mechanisms to bind against the devices.  Just like
we do with I2C drivers.

This is useful when a single driver supports several variants of devices
but it is not possible to detect them in run-time (like non-JEDEC chips
probing in drivers/mtd/devices/m25p80.c), and when platform_data usage is
overkill.

This patch also makes life a lot easier on OpenFirmware platforms, since
with OF we extensively use proper device IDs in modaliases.

Subject: spi: prefix modalias with "spi:"

This makes it consistent with other buses (platform, i2c, vio, ...).  I'm
not sure why we use the prefixes, but there must be a reason.

This was easy enough to do it, and I did it.

Subject: spi_s3c24xx: fix header includes

The driver includes <asm/io.h> where it should be including <linux/io.h>
and also includes <mach/hardware.h> and <asm/dma.h> without using anything
from these.

Subject: spi_s3c24xx: cache device setup data

With the update to the spi_bitbang driver, the transfer setup code is
being called more often, and thus is often re-doing calculations that have
been done before.  The SPI layer allows our driver to add its own data to
each device so add a result cache to each device.

This should also remove the problem where we where directly setting up
registers in the setup call which meant we might overwrite the state of an
extant transfer.,

Subject: spi: McSPI saves CHCONFx too

Previous restore was lazy and only restored CHxCONF when it was needed by
a specific chip select.  This could cause occasional errors on an SPI bus
where multiple chip selects are in use.

Subject: spi: McSPI support for OMAP4

tAdd adds McSPI support for OMAP4430 SDP platform.  All the base addresses
are changed between OMAP1/2/3 and OMAP4.  The fields of the resource
structures are filled at runtime to have McSPI support on OMAP4.

Subject: spi: handle TX-only/RX-only

Support two new half-duplex SPI implementation restrictions, for links
that talk to TX-only or RX-only devices.  (Existing half-duplex flavors
support both transfer directions, just not at the same time.)

Move spi_async() into the spi.c core, and stop inlining it.  Then make
that function perform error checks and reject messages that demand more
than the underlying controller can support.

Based on a patch from Marek Szyprowski which did this only for the
bitbanged GPIO driver.

- * spi_async - asynchronous SPI transfer

- * This call may be used in_irq and other contexts which can't sleep,
- * as well as from task contexts which can sleep.
- *
- * The completion callback is invoked in a context which can't sleep.
- * Before that invocation, the value of message->status is undefined.
- * When the callback is issued, message->status holds either zero (to
- * indicate complete success) or a negative error code.  After that
- * callback returns, the driver which issued the transfer request may
- * deallocate the associated memory; it's no longer in use by any SPI
- * core or controller driver code.
- *
- * Note that although all messages to a spi_device are handled in
- * FIFO order, messages may go to different devices in other orders.
- * Some device might be higher priority, or have various "hard" access
- * time requirements, for example.
- *
- * On detection of any fault during the transfer, processing of
- * the entire message is aborted, and the device is deselected.
- * Until returning from the associated message completion callback,
- * no other spi_message queued to that device will be processed.
- * (This rule applies equally to all the synchronous transfer calls,
- * which are wrappers around this core asynchronous primitive.)

From d00ed3cf6e54312fb59cd1fd6300d787d22373c7 Mon Sep 17 00:00:00 2001
From: Daniel Mack <daniel@caiaq.de>

Subject: rtc: add driver for MXC's internal RTC module

This adds a driver for Freescale's MXC internal real time clock modules.

The code is taken from Freescale's BSPs, but modified to fit the current
kernel coding mechanisms.  Also, the PMIC external clock function was
removed for now to not add dead bits and keep the code as simple as
possible.

Subject: rtc: U300 COH 901 331 RTC driver v3

This adds a driver for the RTC COH 901 331 found in the ST-Ericsson U300
series mobile platforms to the RTC subsystem.  It integrates to the ARM
kernel support recently added to RMKs ARM tree and will be enabled in the
U300 defconfig in due time.

Subject: drivers/rtc: correct error-handling code

This code is not executed before ds1307->rtc has been successfully
initialized to the result of calling rtc_device_register.  Thus the test
that ds1307->rtc is not NULL is always true.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

Subject: rtc: add boot_timesource sysfs attribute

CONFIG_RTC_HCTOSYS allows the kernel to read the system time from the RTC
at boot and resume, avoiding the need for userspace to do so.
Unfortunately userspace currently has no way to know whether this
configuration option is enabled and thus cannot sensibly choose whether to
run hwclock itself or not.  Add a hctosys sysfs attribute which indicates
whether a given RTC set the system clock.

Commit 926b663ce8215ba448960e1ff6e58b67a2c3b99b (gpiolib: allow GPIOs to
be named) already provides naming on the chip level. This patch provides
more flexibility by allowing multiple names where ever in sysfs on a per
GPIO basis.

Subject: gpio: add Intel Moorestown Platform Langwell chip gpio driver

The Langwell chip is the IO hub for Intel Moorestown platform which has a
64-pin gpio block device inside.  It is exposed as a dedicated PCI device.
 We use it to control outside peripheral as well as to do IRQ demuxing.
The gpio block uses MSI to send level type interrupt to IOAPIC.

From: Daniel Glöckner <dg@emlix.com>

Subject: gpiolib: allow poll() on value
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Many gpio chips allow to generate interrupts when the value of a pin
changes.  This patch gives usermode application the opportunity to make
use of this feature by calling poll(2) on the /sys/class/gpio/gpioN/value
sysfs file.  The edge to trigger can be set in the edge file in the same
directory.  Possible values are "none", "rising", "falling", and "both".

Using level triggers is not possible with current sysfs since nothing
changes the GPIO value (and the IRQ keeps triggering).  Edge triggering
will "just work".  Note that if there was an event between read() and
poll(), the poll() returns immediately.

Also note that this version only supports true GPIO interrupts.  Some
later patch might be able to synthesize this behavior by timer-driven
polling; some systems seem to need that.

From fb49b78452503f6cdf8b243ccb40cda81aae9998 Mon Sep 17 00:00:00 2001
From: Kevin Hilman <khilman@mvista.com>
Date: Tue, 22 Sep 2009 16:46:48 -0700
Subject: omapfb: add support for the 3430SDP LCD

The 3430SDP uses the same panel as the 2430SDP.  The main difference are
in the GPIO lines used for panel enable and backlight, and the VAUX
register/commands sent to the TWL4030 power subsystem.

Also, some misc. whitespace cleanups.

From 8fea8844a72f95ef22b108f5dc5c4237019771dd Mon Sep 17 00:00:00 2001
From: "Stanley.Miao" <stanley.miao@windriver.com>
Date: Tue, 22 Sep 2009 16:46:52 -0700
Subject: omapfb: add support for the ZOOM MDK LCD

Add glue to control the OMAP_LDP LCD as a frame buffer device using the
existing dispc.c driver under omapfb.

Patch updated for mainline kernel.  Note that the drivers/video/omap
should be updated to pass omap_lcd_config in platform_data.  The patch
should also be updated to compile if twl4030 is not selected, and
eventually to use the regulator framework.

Subject: omapfb: add support for rotation on the Blizzard LCD ctrl

The LCD controller (EPSON S1D13744) supports rotation (0, 90, 180 and 270
degrees) on hardware just setting the bits 0 and 1 of 0x28 register (LCD
Panel Configuration Register).  Now it is possible to use this caps only
setting the angle degree on var rotate of fb_var_screeninfo using the
FBIOPUT_VSCREENINFO ioctl.

Subject: omapfb: dispc: disable iface clocks along with func clocks

Leaving interface clocks enabled causes dss pwrdm to stay in active state
when mpu is in active state.  This fix puts dss to sleep state when it is
not needed.

Earlier version broke framebuffer on 24xx.  This is fixed by enabling
clocks before trying to access DISPC_IRQSTATUS register.

Subject: omapfb: dispc: allow multiple external IRQ handlers

Previously, the only external (to dispc.c) IRQ handler was RFBI's frame
done handler.  dispc's IRQ framework was very dumb: you could only have
one handler, and the semantics of {request,free}_irq were odd, to say the
least.

The new framework allows multiple consumers to register arbitrary IRQ
masks.

From d480ace08d5b59133575e672a0bd1c97b0f8400f Mon Sep 17 00:00:00 2001
From: Pavel Machek <pavel@ucw.cz>
Date: Tue, 22 Sep 2009 16:47:03 -0700
Subject: fbdev: framebuffer support for HTC Dream

Add a framebuffer driver for Qualcomm MSM/QSD SoCs, tested on HTC Dream
smartphone (aka T-Mobile G1, aka ADP1).

Brian said:

  I did the original quick and dirty version for bringup.  Rebecca took
  over and (re)wrote the bulk of the driver, getting things stable for
  production ship of Dream and Sapphire, and Dima is currently adding
  support for later Qualcomm chipsets (QSD8x50, etc).

added `hres * (1 << color_mode)' to the boolean testing videomode and
depth.

Subject: davinci: fb: Frame Buffer driver for TI DA8xx/OMAP-L1xx

Add LCD controller (LCDC) driver for TI's DA8xx/OMAP-L1xx architecture.
LCDC specifications can be found at http://www.ti.com/litv/pdf/sprufm0a.

LCDC on DA8xx consists of two independent controllers, the Raster
Controller and the LCD Interface Display Driver (LIDD) controller.  LIDD
further supports character and graphic displays.

This patch adds support for the graphic display (Sharp LQ035Q3DG01) found
on the DA830 based EVM.  The EVM details can be found at:
http://support.spectrumdigital.com/boards/dskda830/revc/.

+================================
+Driver for EP93xx LCD controller
+================================
+
+The EP93xx LCD controller can drive both standard desktop monitors and
+embedded LCD displays. If you have a standard desktop monitor then you
+can use the standard Linux video mode database. In your board file:
+
+	static struct ep93xxfb_mach_info some_board_fb_info = {
+		.num_modes	= EP93XXFB_USE_MODEDB,
+		.bpp		= 16,
+	};
+
+If you have an embedded LCD display then you need to define a video
+mode for it as follows:
+
+	static struct fb_videomode some_board_video_modes[] = {
+		{
+			.name		= "some_lcd_name",
+			/* Pixel clock, porches, etc */
+		},
+	};
+
+Note that the pixel clock value is in pico-seconds. You can use the
+KHZ2PICOS macro to convert the pixel clock value. Most other values
+are in pixel clocks. See Documentation/fb/framebuffer.txt for further
+details.
+
+The ep93xxfb_mach_info structure for your board should look like the
+following:
+
+	static struct ep93xxfb_mach_info some_board_fb_info = {
+		.num_modes	= ARRAY_SIZE(some_board_video_modes),
+		.modes		= some_board_video_modes,
+		.default_mode	= &some_board_video_modes[0],
+		.bpp		= 16,
+	};
+
+The framebuffer device can be registered by adding the following to
+your board initialisation function:
+
+	ep93xx_register_fb(&some_board_fb_info);
+
+=====================
+Video Attribute Flags
+=====================
+
+The ep93xxfb_mach_info structure has a flags field which can be used
+to configure the controller. The video attributes flags are fully
+documented in section 7 of the EP93xx users' guide. The following
+flags are available:
+
+EP93XXFB_PCLK_FALLING		Clock data on the falling edge of the
+				pixel clock. The default is to clock
+				data on the rising edge.
+
+EP93XXFB_SYNC_BLANK_HIGH	Blank signal is active high. By
+				default the blank signal is active low.
+
+EP93XXFB_SYNC_HORIZ_HIGH	Horizontal sync is active high. By
+				default the horizontal sync is active low.
+
+EP93XXFB_SYNC_VERT_HIGH		Vertical sync is active high. By
+				default the vertical sync is active high.
+
+The physical address of the framebuffer can be controlled using the
+following flags:
+
+EP93XXFB_USE_SDCSN0		Use SDCSn[0] for the framebuffer. This
+				is the default setting.
+
+EP93XXFB_USE_SDCSN1		Use SDCSn[1] for the framebuffer.
+
+EP93XXFB_USE_SDCSN2		Use SDCSn[2] for the framebuffer.
+
+EP93XXFB_USE_SDCSN3		Use SDCSn[3] for the framebuffer.
+
+==================
+Platform callbacks
+==================
+
+The EP93xx framebuffer driver supports three optional platform
+callbacks: setup, teardown and blank. The setup and teardown functions
+are called when the framebuffer driver is installed and removed
+respectively. The blank function is called whenever the display is
+blanked or unblanked.
+
+The setup and teardown devices pass the platform_device structure as
+an argument. The fb_info and ep93xxfb_mach_info structures can be
+obtained as follows:
+
+	static int some_board_fb_setup(struct platform_device *pdev)
+	{
+		struct ep93xxfb_mach_info *mach_info = pdev->dev.platform_data;
+		struct fb_info *fb_info = platform_get_drvdata(pdev);
+
+		/* Board specific framebuffer setup */
+	}
+
+======================
+Setting the video mode
+======================
+
+The video mode is set using the following syntax:
+
+	video=XRESxYRES[-BPP][@REFRESH]
+
+If the EP93xx video driver is built-in then the video mode is set on
+the Linux kernel command line, for example:
+
+	video=ep93xx-fb:800x600-16@60
+
+If the EP93xx video driver is built as a module then the video mode is
+set when the module is installed:
+
+	modprobe ep93xx-fb video=320x240
+
+==============
+Screenpage bug
+==============
+
+At least on the EP9315 there is a silicon bug which causes bit 27 of
+the VIDSCRNPAGE (framebuffer physical offset) to be tied low. There is
+an unofficial errata for this bug at:
+	http://marc.info/?l=linux-arm-kernel&m=110061245502000&w=2
+
+By default the EP93xx framebuffer driver checks if the allocated physical
+address has bit 27 set. If it does, then the memory is freed and an
+error is returned. The check can be disabled by adding the following
+option when loading the driver:
+
+      ep93xx-fb.check_screenpage_bug=0
+
+In some cases it may be possible to reconfigure your SDRAM layout to
+avoid this bug. See section 13 of the EP93xx users' guide for details.

Subject: viafb: remove duplicated CX700 register init

The current code initializes the register for CX700 chips 2 times due to a
missing break as discovered by Harald Welte.

As CX700 and VX800 have exactly the same register initialization we can
use one for both to avoid duplicated code.

As this is a pure code cleanup no measurable runtime effects are expected.

Subject: viafb: remove temporary start address setting

Currently the start address is set to an initial value every time
viafb_setmode is called.

This is not done consistently along graphic cores and not even the whole
address but often only parts of it.  On top of that it seems useless as
the real/final address will be set by viafb_set_start_addr a few lines
later.

Remove this superfluous initalization to shrink register initalization and
as a start to decouple primary and secondary display.  Code cleanup, no
notable runtime change expected.

Subject: viafb: merge viafb_update_viafb_par in viafb_update_fix

Shrink and merge viafb_update_viafb_par.  This removes a lot of duplicated
data in viafb_par.  Use the relevant data of fb_info instead.  On the way
it removes an inconsistency in handling a second framebuffer which only
worked because viafbinfo1->par is modified to point to the same viafb_par
as viafbinfo->par.

Code cleanup only, no runtime change expected.

Subject: viafb: split viafb_set_start_addr up

Move individual start address setting to viafb_set_primary_address and
viafb_set_secondary_address and make it more flexible to reuse it for
panning.  Using central functions makes it easier to follow HW
manipulations.

Remove crt locking as it should be only needed for timing manipulation.
Move iga_path manipulation to via_pci_probe.

Remove memset for screen cleaning as it is currently done only for the
second screen.  This is not needed for normal operation but has a little
chance of causing unwanted display artifacts.  This can be fixed later
more consistent and more efficient (using viafb_fillrect) if needed.

This is a code clenup, no notable runtime changes expected.

Subject: viafb: fix ioremap_nocache error handling

Correct the returned error code for remapping the video framebuffer.
Introduce error handling for remapping MMIO register address space to
avoid a NULL pointer dereference.  Disable hardware acceleration if
remapping MMIO register address space failed as those registers are only
used for hardware acceleration.

Subject: viafb: clean up viamode.h

Remove unneeeded declarations from the header and makes it more
maintainable by evaluating the array size in the file the array exist in
and exporting it via variables.  This removes the need to keep the array
size in the header in sync with the real array size.

Subject: viafb: remove duplicated mode information

Remove the mode information from viafbdev.c and uses the one of viamode.c
instead.  This is possible because horizontal and vertical address are the
same as horizontal and vertical resolution.  The reduced blanking modes in
the table are no problem because they have a higher index than the normal
modes and therefore always the normal modes are selected just as the old
behaviour.

Subject: viafb: clean up duoview

Clean the duoview handling up by replacing the varible with the funtion in
the only place where it is used.  This is a code cleanup only, no runtime
change expected.

Subject: viafb: clean up virtual memory handling

Clean the handling of ioremapped video memory up.  The following changes
were made:

info->screen_base - viafb_FB_MM
(VRAM offset calculation) was replaced by
info->fix.smem_start - viafbinfo->fix.smem_start
which is essentially the same calculation but done with physical instead
virtual addresses.

*->fbmem_virt
was replaced by
viafbinfo->screen_base
This is true for viafbinfo and viafbinfo1 as the par pointers are equal.

An early initialization of viafbinfo1->fix.smem* was removed as done later
in viafb_setup_fixinfo.

This patch highlights that the only usage of the ioremapped video memory
in the driver is for hardware cursor handling.  Even if it has to hold the
used virtual screen mapped for old-fashioned read/write calls (vs.
mmap'ed) a lot virtual memory could be saved by only ioremapping on
demand.

Code cleanup, no runtime changes expected.

Subject: viafb: remove unused video device stuff

Remove everything related to video devices from the driver as it did not
influence the driver operation.  This patch does change the userspace
behaviour as it removes two IOCTLs and one module parameter.  But this is
good as it removes useless stuff and helps the user to figure out the
options that do affect the driver behaviour (which are still too many).

Subject: viafb: remove LVDS initialization

At least for VX800 this initialization is not very good as some parts of
the register are written with reserved values.  This makes the display go
white in some configurations and not usable until the framebuffer is
removed.  It's better to not initialize it as it allows to use a
previously (by BIOS) correctly configured display.

This patch makes some displays work but might cause problems on others.
This is bad but can not be easily avoided.  If this causes some
regressions it's probably the best to fix it in the 'active' display setup
code.

Subject: viafb: another small cleanup of viafb_par

This removes the completly useless io variable as well as the temporary
used variables mmio_base and mmio_len in favor to use directly the fb_info
variables.

This is a code cleanup only, no runtime change expected.

Subject: viafb: improve viafb_par

This patch introduces viafb_shared and is the beginning of a smooth
transition to use it.

viafb_shared should contain all general, non-surface specific data that
should be shared along all viafb framebuffers while viafb_par should only
contain things that are specific to each surface or in other words extend
fb_info.  This change is intended to clean the dual/multi framebuffer
handling up.

This removes the annoyance that viafbinfo1->par points to a different
structure than viaparinfo1.

As the last change is fundamental it is difficult to ensure that all parts
of the driver do not depend on the previous brokenness but the chance of
regressions is very low.

Subject: viafb: 2D engine rewrite

This patch is a completly rewritten 2D engine.  The engine is no longer in
a default state but reinitialized every time to allow usage for both
framebuffers regardless of their settings.

The whole engine handling is concentrated in a big function which takes 16
parameters.  Although the number of parameters is worryingly it is good to
have a single funtion to deal with this stuff as it allows to easily
support different engines and avoids some code duplication.

On the way support for the new 2D engine in VX800 was added.  As the with
less code duplication but it is probably better to duplicate the code as
this way is easier to walk if VIA ever decides to release a new engine
which changes anything the driver touches.

The engine support for VX800 gives a notable boost in speed.  There are no
known regressions but as this patch changes paths I do neither have the
hardware nor documentation to check and has the possibility to put the
system in a critical state heavy testing is appreciated.

From 5016af53ebbd1450c2656c94dfbd1dad15c19f60 Mon Sep 17 00:00:00 2001
From: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
Date: Tue, 22 Sep 2009 16:47:28 -0700
Subject: viafb: cleanup viafb_cursor

Clean the hardware cursor handling up.

The most notable change is that it no longer buffers the values in
viacursor but uses the ones in cursor instead as they are guaranteed to be
always valid.

Furthermore it uses local instead global variables where possible, moves
the cursor variable in shared as only one hardware cursor is supported and
returns an error if memory allocation fails.  Last but not least it fixes
a too small buffer (as u32 has only 4 and not 32 bytes) but this did not
produce any known problems.

This is mostly a code cleanup, no negative runtime changes are expected.

From 2d6e8851f608bd0c811f2df83eeff4ad8631e723 Mon Sep 17 00:00:00 2001
From: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>

Subject: viafb: improve pitch handling

Split the pitch handling up and replaces the calculation from virtual xres
and bpp with fix.line_length which already contains the pitch and does not
add any constrains for the virtual resolution.

Also add a bit to the second pitch which the documentation mentions but
which was ignored by the driver.

Although it is a bit unclear what the right pitch for some LCD modes is
this patch should have no negative runtime impact.

Subject: viafb: hardware acceleration initialization cleanup

The main motivation of this patch was to merge the three initialization
functions in one and clean it up. However as some changes in other code
areas where needed to do it right some small other changes were made.

Changes to viafb_par:

io_virt renamed as engine_mmio and moved to shared
VQ_start renamed as vq_vram_addr and moved to shared
VQ_end removed as it is easily recalculatable

vq_vram_addr is not strictly needed but keep it to track where we
allocated video memory.  The memory allocated for the virtual queue was
shrunk to VQ_SIZE as VQ_SIZE+CURSOR_SIZE looked like a bug to me.  But to
be honest I don't have the faintest idea what virtual queues are for in
the graphic hardware and whether the driver needs them in any way.  I only
know that they aren't directly accessed by the driver and so the only
potential current use would be as hardware internal buffers.  For now keep
them to avoid regressions and only remove the double cursor allocation.

The most changes were caused by renames and the mentioned structure
changes so the chance of regressions is pretty low.  The meaning of
viafb_accel changed slightly as previously it was changed back and forth
in the code and allowed to enable the hardware acceleration by software if
previously disabled.  The new behaviour is that viafb_accel=0 always
prevents hardware acceleration.  With viafb_accel!=0 the acceleration can
be freely choosen by set_var.  This means viafb_accel is a diagnostic tool
and if someone has to use viafb_accel=0 the driver needs to be fixed.

As this is mostly a code cleanup no regressions beside the slightly change
of viafb_accel is expected.

Subject: fb: fix fb_pan_display range check

Fix the range check for panning.  The current code fails to detect some
invalid values (very high ones that can occur if an app tries to move
further up/left than 0,0) as the check uses the unknown values for
calculation so that an overflow can occur.

To fix this it is sufficient to move the calculation to the right side to
use only trusted values.

Kai Jiang detected this problem and proposed an initial patch.

Subject: video: console, use DIV_ROUND_UP

Use DIV_ROUND_UP explicitly instead of manual shifts and adds.  It makes
the code more readable and consistent (sometimes there were shifts,
sometimes divs).

There is no change on the assembly level (compilers should do the right
job).

Subject: s3c2410fb: fix clockrate calculation

In the final part of the calculation for the tft display clockrate we
divide the output pf s3c2410fb_calc_pixclk() by 2 which leaves us with a
rounding error if the result is odd.

Change to using DIV_ROUND_UP() to ensure that we always choose a higher
divisor and thus a lower frequency.

Subject: fb: do not ignore fb_set_par errors

At the moment about half of the framebuffer drivers can return an error
code in fb_set_par. Until now it would be silently ignored by fbmem.c
and fbcon.c. This patch fixes fbmem.c to return the error code and
restore var on error.

But it is not clear in which video mode the device is when fb_set_par
fails.  It would be good and reasonable if it were in the old state but
there is no guarantee that this is true for all existing drivers.
Additionally print a message if a failing fb_set_par is detected in
fbmem.c or fbcon.c.

Although most errors should be caught by the previous fb_check_var some
errors can't as they are dynamic (memory allocations, ...) and can only be
detected while performing the operations which is forbidden in
fb_check_var.

This patch shouldn't have a negative impact on normal operation as all
drivers return 0 on success.  The impact in case of error depends heavily
on the driver and caller but it's expected to be better than before.

Subject: matroxfb: make CONFIG_FB_MATROX_MULTIHEAD=y mandatory

I would like to get rid of option CONFIG_FB_MATROX_MULTIHEAD and just
always enable it.  There are many reasons for doing this:

* CONFIG_FB_MATROX_MULTIHEAD=y is what all x86 distributions do, so it
  definitely works or we would know by now.

* Building the matroxfb driver with CONFIG_FB_MATROX_MULTIHEAD not set
  results in the following build warning:

drivers/video/matrox/matroxfb_crtc2.c: In function 'matroxfb_dh_open':
drivers/video/matrox/matroxfb_crtc2.c:265: warning: the address of 'matroxfb_global_mxinfo' will always evaluate as 'true'
drivers/video/matrox/matroxfb_crtc2.c: In function 'matroxfb_dh_release':
drivers/video/matrox/matroxfb_crtc2.c:285: warning: the address of 'matroxfb_global_mxinfo' will always evaluate as 'true'

This is nothing to be worried about, the driver will work fine, but build
warnings are still annoying.

* The trick to get multihead support without CONFIG_FB_MATROX_MULTIHEAD,
  which is described in the config help text, no longer works: you can't
  load the same kernel module more than once.

* I fail to see how CONFIG_FB_MATROX_MULTIHEAD=y would make the code
  significantly slower, contrary to what the help text says.  A few extra
  parameters on the stack here and there can't really slow things down in
  comaprison to the rest of the code, and register access.

* The driver built without CONFIG_FB_MATROX_MULTIHEAD is larger than the
  driver build with CONFIG_FB_MATROX_MULTIHEAD=y by 8%.

* One less configuration option makes things simpler.  We add options
  all the time, being able to remove one for once is nice.  It improves
  testing coverage.  And I don't think the Matrox adapters are still
  popular enough to warrant overdetailed configuration settings.

* We should be able to unobfuscate the driver code quite a bit after
  this change (patches follow.)

From fc2d10ddfc8989e82f74d2a38c7d6bfa45bcaba9 Mon Sep 17 00:00:00 2001
From: Jean Delvare <khali@linux-fr.org>
Date: Tue, 22 Sep 2009 16:47:48 -0700
Subject: matroxfb: get rid of unneeded macros ACCESS_FBINFO and MINFO

With multihead support always enabled, these macros are no longer needed
and make the code harder to read.

Subject: matroxfb: get rid of unneeded macros WPMINFO and friends

With multihead support always enabled, these macros are no longer needed
and make the code harder to read.

Subject: matroxfb: get rid of unneeded macro MINFO_FROM

With multihead support always enabled, macros MINFO_FROM and
MINFO_FROM_INFO are no longer needed and make the code harder to read.

Subject: matroxfb: get rid of CONFIG_FB_MATROX_32MB

CONFIG_FB_MATROX_32MB is always enabled, so there is no point in having
ifdefs all around.  And it is bad practice to use CONFIG_* as a name for
something which is not a Kconfig option.

Subject: fbcon: only unbind from console if successfully registered

Attempting to unload a framebuffer module calls unregister_framebuffer()
which in turn gets fbcon to release it.  If fbcon has no framebuffers
linked to a console, it will also unbind itself from the console driver.
However, if fbcon never registered itself as a console driver, the unbind
will fail causing the framebuffer device entry to persist.  In most cases
this failure will result in an oops when attempting to access the now
non-existent device.

This patch ensures that the fbcon unbind request will succeed even if a
bind was never done.  It tracks if a successful bind ever occurred & will
only attempt to unbind if needed.  If there never was a bind, it simply
returns with no error.

Subject: vgacon: prevent vgacon_deinit from touching the hardware for inactive
 consoles.

fbcon makes the (reasonable) assumption that it only needs to program the
hardware once, when fbcon_init() is called for the foreground console.

This doesn't always play well with vgacon because vgacon_deinit() is only
doing its job when the last console it owns is closed (when switching from
vgacon to fbcon, that's usually *after* fbcon_init() has set the new
mode).

Depending on the hardware this can cause the wrong framebuffer location to
be scanned out (e.g.  reproduced on nv05 with the nouveau framebuffer
driver).

Subject: V3 minixfs: add missing directory type checking

There are a few places in the Minix FS code where the "inode" field of a
minix_dir_entry is used without checking first to see if the dirent is
really a minix3_dir_entry.  The inode number in a V1/V2 dirent is 16 bits,
whereas that in a V3 dirent is 32 bits.

Accessing it as a 16 bit field when it really should be accessed as a 32
bit field probably kinda sorta works on a little-endian machine, but leads
to some rather odd behaviour on big-endian machines.

Subject: ext2: fix format string compile warning (ino_t)

Unlike on most other architectures ino_t is an unsigned int on s390.  So
add an explicit cast to avoid this compile warning:

fs/ext2/namei.c: In function 'ext2_lookup':
fs/ext2/namei.c:73: warning: format '%lu' expects type 'long unsigned int', but argument 4 has type 'ino_t'

Subject: hostap: Revert a toxic part of the conversion to net_device_ops

As the hostap driver was converted to use net_device_ops, a mistake was
made in hostap_main.c (commit 5ae4efbcd2611562a8b93596be034e63495706a5).
Originally, the tx_queue_len was set to 0 for every other interface than
HOSTAP_INTERFACE_MASTER, but the new fragment of code sets tx_queue_len to
0 only for HOSTAP_INTERFACE_MASTER. The opposite of the previous
behavior makes the driver to drop all packets in AP mode.

Change the way 0 is assigned to tx_queue_len according to the original
logic.

When processing MIB interrupts, OFDM and CCK error
handling routines for low RSSI values have to be invoked
only when the channel mode is 11G/11B. Since HT channels
will also fall under the bands 2Ghz/5Ghz, check appropriately.

WEXT's "struct iw_freq" can also be used to handle a channel. This patch now
uses cfg80211_wext_freq() instead of hand-converting the frequency. That
allows user-space to specify channels as well, like with SIOCSIWFREQ.

Subject: b43: Fix resume failure

This fixes a resume failure where a signal is pending on resume
so the firmware upload fails.
This removes the interruptible sleep, because we don't really need it.
In the worst case (with broken firmware) the sleep loop will take 1 second.
In the common case (working firmware), it will only take a few milliseconds.
So we don't really need to be interruptible.

Subject: iwlwifi: fix potential rx buffer loss

RX handling maintains a few lists that keep track of the RX buffers.
Buffers move from one list to the other as they are used, replenished, and
again made available for usage. In one such instance, when a buffer is used
it enters the "rx_used" list. When buffers are replenished an skb is
attached to the buffer and it is moved to the "rx_free" list. The problem
here is that the buffer is first removed from the "rx_used" list _before_ the
skb is allocated. Thus, if the skb allocation fails this buffer remains
removed from the "rx_used" list and is thus lost for future usage.

Fix this by first allocating the skb before trying to attach it to a list.
We add an additional check to not do this unnecessarily.

Subject: iwlwifi: find the correct first antenna

We can not assume antenna "A" is the first valid anttena for
all the NIC. Need to make sure choice the correct antenna based on
h/w configuration for transmit to avoid sending frame on invalid
antenna

Subject: iwlwifi: disable powersave for 4965

There's a bug in 4965 powersave that appears to
be related to the way it keeps track of its data
during sleep, but we haven't found it yet. Due to
that, using powersave may spontaneously cause the
device to SYSASSERT when transitioning from sleep
to wake. Therefore, disable powersave for 4965,
until (if ever, unfortunately) we can identify
and fix the problem.

Cf. http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=1982
which was closed, but now has re-appeared with
IDLE mode, which probably means we never really
fixed it.

Subject: cfg80211: fix SME connect

There's a check saying
	/* we're good if we have both BSSID and channel */
	if (wdev->conn->params.bssid && wdev->conn->params.channel) {

but that isn't true -- we need the BSS struct. This leads
to errors such as

    Trying to associate with 00:1b:53:11:dc:40 (SSID='TEST' freq=2412 MHz)
    ioctl[SIOCSIWFREQ]: No such file or directory
    ioctl[SIOCSIWESSID]: No such file or directory
    Association request to the driver failed
    Associated with 00:1b:53:11:dc:40

in wpa_supplicant, as reported by Holger.

Instead, we really need to have the BSS struct, and if we
don't, then we need to initiate a scan for it. But we may
already have the BSS struct here, so hang on to it if we
do and scan if we don't.

Subject: b43: Add Soft-MAC SDIO device support

This adds support for Soft-MAC SDIO devices to b43.
The driver still lacks some fixes for SDIO devices, so it's currently
marked as BROKEN.

Subject: b43: Add optional verbose runtime statistics

This adds support for verbose runtime statistics.
It defaults to off and must be enabled in debugfs, if desired.
The first measurement may be incorrect, because statistics are not cleared
after they got enabled through debugfs.

Subject: b43: Add LP PHY Analog Switch Support

The current verison of b43 uses "b43_phyop_switch_analog_generic" for A,
G and LP phys.

According to the spec, this is the wrong behaviour for the LP PHY
(see: http://bcm-v4.sipsolutions.net/802.11/PHY/Anacore )

While no problems on the x86 plattform where seen, this leads to a crash
on the BCM5354 SoC (MIPS 32 LE plattform).
This patch implements the analog switch for LP PHYs according to the
specs. It fixes the crash

Subject: ath9k: Fix chip wakeup issue

Waking up the chip after powering it down fails sometimes.
In this case the CPU is locked for 200ms. Reduce this
interval to 10ms to avoid excessive busy looping.

Subject: mac80211: fix DTIM setting

When the DTIM setting is read from beacons, mac80211 will
assume it is 1 if the TIM IE is not present or the value
is 0. This sounds fine, but the same function processes
probe responses as well, which don't have a TIM IE. This
leads to overwriting any values previously parsed out of
beacon frames.

Thus, instead of checking for the presence of the TIM IE
when setting the default, simply check whether the DTIM
period value is valid already. If the TIM IE is not there
then the value cannot be valid (it is initialised to 0)
and probe responses received after beacons will not lead
to overwriting an already valid value.

Subject: iwlwifi: do not send sync command while holding spinlock

commit 10c994ca70e8e94bbc85a5bf13de5911ee8de4d2 "iwlwifi: fix remove key
error" fixed an error reported by mac80211 during interface down. The fix
involved changing an async command to synchronous. Unfortunately this was
inside a spinlock section in which we cannot sleep.

Modify the sending of the command back to async. This causes the mac80211
error "mac80211-phy0: failed to remove key (0, ff:ff:ff:ff:ff:ff) from
hardware (-16)." to return. This error is not serious since this occurs
during interface down and the keys will be cleared anyway when ucode is
unloaded. Having this error message is thus less serious than a potential
deadlock introduced when sleeping while holding a spinlock. We will have to
find another fix for that error.

This is a revert of the abovementioned commit.

Subject: iwlwifi: reduce noise when skb allocation fails

Replenishment of receive buffers is done in the tasklet handling
received frames as well as in a workqueue. When we are in the tasklet
we cannot sleep and thus attempt atomic skb allocations. It is generally
not a big problem if this fails since iwl_rx_allocate is always followed
by a call to iwl_rx_queue_restock which will queue the work to replenish
the buffers at a time when sleeping is allowed.

We thus add the __GFP_NOWARN to the skb allocation in iwl_rx_allocate to
reduce the noise if such an allocation fails while we still have enough
buffers. We do maintain the warning and the error message when we are low
on buffers to communicate to the user that there is a potential problem with
memory availability on system

This addresses issue reported upstream in thread "iwlagn: order 2 page
allocation failures" in
http://thread.gmane.org/gmane.linux.kernel.wireless.general/39187

When cfg80211 is instructed to connect, it always

which clearly is wrong when using wpa_supplicant.
Don't overwrite the setting, and rely on it being
false when wpa_supplicant is not running, instead
set it to true when we have keys.

Subject: ath9k: Fix RFKILL bugs

This patch fixes 2 issues in RFKILL:

* Calling wiphy_rfkill_stop_polling() in ath9k_stop
  would mean that the driver cannot report HW status
  when the radio is re-enabled. Move this to ath_detach().

* Calling ath_radio_{enable/disable} without checking the current
  state results in ath_radio_enable() being called repeatedly
  for every invocation of rfkill_poll(). This is not needed
  in any case since wiphy_rfkill_set_hw_state() would call
  ->stop() if the radio has been disabled.

Subject: x86: mce: Use safer ways to access MCE registers

Use rdmsrl_safe() when accessing MCE registers. While in
theory we always 'know' which ones are safe to access from
the capability bits, there's a lot of hardware variations
and reality might differ from theory, as it did in this case:

   http://bugzilla.kernel.org/show_bug.cgi?id=14204

[    0.010016] mce: CPU supports 5 MCE banks

[    0.011998] ESI: 00000000 EDI: 8c000000 EBP: 00000405 ESP: c17d5eac

So WARN_ONCE() instead of crashing the box.

( also fix a number of stylistic inconsistencies in the code. )

Note, we might still crash in wrmsrl() if we get that far, but
we shouldnt if the registers are truly inaccessible.

Subject: fs: change sys_truncate length parameter type

For this system call user space passes a signed long length parameter,
while the kernel side takes an unsigned long parameter and converts it
later to signed long again.

This has led to bugs in compat wrappers see e.g.  dd90bbd5 "powerpc: Add
compat_sys_truncate".  The s390 compat wrapper for this functions is
broken as well since it also performs zero extension instead of sign
extension for the length parameter.

In addition if hpa comes up with an automated way of generating
compat wrappers it would generate a wrong one here.

So change the length parameter from unsigned long to long.

Subject: ASoC: DaVinci: Fix divide by zero error during 1st execution

When both playback and capture stream were open
davinci_i2s_hw_params was setting parameters for
the wrong stream. The fix for davinci_i2s_hw_params
is sufficient, but it looks like a race still happens
in davici_pcm_open. This patch also makes the race smaller
but the next patch provides a better fix.

Commit ebd2c8f6d2ec4012c267ecb95e72a57b8355a705 removed struct uart_info and
commit bdc04e3174e18f475289fa8f4144f66686326b7e further moved delta_msr_wait.
Fix up the MN10300 on-chip serial port drivers to comply with this.

Subject: ASoC: DaVinci: Correct McASP FIFO initialization

McASP write FIFO registers should be modified for playback and read FIFO
registers for capture. Check the PCM mode before manipulating the
FIFO registers. Currently, irrespective of playback/capture both the
FIFOs are enabled or disbaled. This resulted in errors in audio loopback
mode.

Subject: rcu: Clean up code based on review feedback from Josh Triplett

These issues identified during an old-fashioned face-to-face code
review extended over many hours.

o	Bury various forms of the "rsp->completed == rsp->gpnum"
	comparison into an rcu_gp_in_progress() function, which has
	the beneficial side-effect of forcing consistent use of
	ACCESS_ONCE().

o	Replace hand-coded arithmetic with DIV_ROUND_UP().

o	Bury several "!list_empty(&rnp->blocked_tasks[rnp->gpnum & 0x01])"
	instances into an rcu_preempted_readers() function, as this
	expression indicates that there are no readers blocked
	within RCU read-side critical sections blocking the current
	grace period.  (Though there might well be similar readers
	blocking the next grace period.)

o	Remove a dangling rcu_restart_cpu() declaration that has
	been dangling for almost 20 minor releases of the kernel.

From 1eba8f84380bede3c602bd7758dea96925cead01 Mon Sep 17 00:00:00 2001
From: "Paul E. McKenney" <paulmck@linux.vnet.ibm.com>
Date: Wed, 23 Sep 2009 09:50:42 -0700
Subject: rcu: Clean up code based on review feedback from Josh Triplett, part
 2

These issues identified during an old-fashioned face-to-face code
review extending over many hours.

o	Add comments for tricky parts of code, and correct comments
	that have passed their sell-by date.

o	Get rid of the vestiges of rcu_init_sched(), which is no
	longer needed now that PREEMPT_RCU is gone.

o	Move the #include of rcutree_plugin.h to the end of
	rcutree.c, which means that, rather than having a random
	collection of forward declarations, the new set of forward
	declarations document the set of plugins.  The new home for
	this #include also allows __rcu_init_preempt() to move into
	rcutree_plugin.h.

o	Fix rcu_preempt_check_callbacks() to be static.

mips allmodconfig:

    CRED: Separate task security context from task_struct

I think.

It's way too large to be inlined anyway.

Dunno if this needs an EXPORT_SYMBOL() yet.

Subject: 9p: Fix the incorrect update of inode size in v9fs_file_write()

When using the cache=loose flags, the inode's size was not being
updated correctly on a remote write. Thus subsequent reads of
the whole file resulted in a truncated read. Fix it.

Subject: 9p: Add fscache support to 9p

This patch adds a persistent, read-only caching facility for
9p clients using the FS-Cache caching backend.

When the fscache facility is enabled, each inode is associated
with a corresponding vcookie which is an index into the FS-Cache
indexing tree. The FS-Cache indexing tree is indexed at 3 levels:
- session object associated with each mount.
- inode/vcookie
- actual data (pages)

A cache tag is chosen randomly for each session. These tags can
be read off /sys/fs/9p/caches and can be passed as a mount-time
parameter to re-attach to the specified caching session.

Subject: KEYS: Have the garbage collector set its timer for live expired keys

The key garbage collector sets a timer to start a new collection cycle at the
point the earliest key to expire should be considered garbage.  However, it
currently only does this if the key it is considering hasn't yet expired.

If the key being considering has expired, but hasn't yet reached the collection
time then it is ignored, and won't be collected until some other key provokes a
round of collection.

Make the garbage collector set the timer for the earliest key that hasn't yet
passed its collection time, rather than the earliest key that hasn't yet
expired.

Subject: IB/mad: Fix lock-lock-timer deadlock in RMPP code

Holding agent->lock across cancel_delayed_work() (which does
del_timer_sync()) in ib_cancel_rmpp_recvs() leads to lockdep reports of
possible lock-timer deadlocks if a consumer ever does something that
connects agent->lock to a lock taken in IRQ context (cf
http://marc.info/?l=linux-rdma&m=125243699026045).

Fix this by changing the list items to a new state "CANCELING" while
holding the lock, and then canceling the delayed work without holding
the lock.  If the delayed work runs after the lock is dropped, it will
see the state is CANCELING and return immediately, so the list will
stay stable while we traverse it with the lock not held.

Subject: SELinux: do not destroy the avc_cache_nodep

The security_ops reset done when SELinux is disabled at run time is done
after the avc cache is freed and after the kmem_cache for the avc is also
freed.  This means that between the time the selinux disable code destroys
the avc_node_cachep another process could make a security request and could
try to allocate from the cache.  We are just going to leave the cachep around,
like we always have.

SELinux:  Disabled at runtime.

Subject: NFS/RPC: fix problems with reestablish_timeout and related code.

[[resending with correct cc:  - "vfs.kernel.org" just isn't right!]]

xprt->reestablish_timeout is used to cause TCP connection attempts to
back off if the connection fails so as not to hammer the network,
but to still allow immediate connections when there is no reason to
believe there is a problem.

It is not used for the first connection (when transport->sock is NULL)
but only on reconnects.

It is currently set:

 a/ to 0 when xs_tcp_state_change finds a state of TCP_FIN_WAIT1
    on the assumption that the client has closed the connection
    so the reconnect should be immediate when needed.
 b/ to at least XS_TCP_INIT_REEST_TO when xs_tcp_state_change
    detects TCP_CLOSING or TCP_CLOSE_WAIT on the assumption that the
    server closed the connection so a small delay at least is
    required.
 c/ as above when xs_tcp_state_change detects TCP_SYN_SENT, so that
    it is never 0 while a connection has been attempted, else
    the doubling will produce 0 and there will be no backoff.
 d/ to double is value (up to a limit) when delaying a connection,
    thus providing exponential backoff and
 e/ to XS_TCP_INIT_REEST_TO in xs_setup_tcp as simple initialisation.

So you can see it is highly dependant on xs_tcp_state_change being
called as expected.  However experimental evidence shows that
xs_tcp_state_change does not see all state changes.
("rpcdebug -m rpc trans" can help show what actually happens).

Results show:
 TCP_ESTABLISHED is reported when a connection is made.  TCP_SYN_SENT
 is never reported, so rule 'c' above is never effective.

 When the server closes the connection, TCP_CLOSE_WAIT and
 TCP_LAST_ACK *might* be reported, and TCP_CLOSE is always
 reported.  This rule 'b' above will sometimes be effective, but
 not reliably.

 When the client closes the connection, it used to result in
 TCP_FIN_WAIT1, TCP_FIN_WAIT2, TCP_CLOSE.  However since commit
 f75e674 (SUNRPC: Fix the problem of EADDRNOTAVAIL syslog floods on
 reconnect) we don't see *any* events on client-close.  I think this
 is because xs_restore_old_callbacks is called to disconnect
 xs_tcp_state_change before the socket is closed.
 In any case, rule 'a' no longer applies.

So all that is left are rule d, which successfully doubles the
timeout which is never rest, and rule e which initialises the timeout.

Even if the rules worked as expected, there would be a problem because
a successful connection does not reset the timeout, so a sequence
of events where the server closes the connection (e.g. during failover
testing) will cause longer and longer timeouts with no good reason.

This patch:

 - sets reestablish_timeout to 0 in xs_close thus effecting rule 'a'
 - sets it to 0 in xs_tcp_data_ready to ensure that a successful
   connection resets the timeout
 - sets it to at least XS_TCP_INIT_REEST_TO after it is doubled,
   thus effecting rule c

I have not reimplemented rule b and the new version of rule c
seems sufficient.

I suspect other code in xs_tcp_data_ready needs to be revised as well.
For example I don't think connect_cookie is being incremented as often
as it should be.

Subject: NFS: Add nfs_alloc_parsed_mount_data

Allocating nfs_parsed_mount_data and setting up the defaults is nearly
the same for both nfs and nfs4 mounts.

Both paths seem to use nfs_validate_transport_protocol(), so setting a
default value for nfs_server.protocol ought to be unnecessary.

Subject: NFS: Propagate 'fsc' mount option through automounts

Propagate the NFS 'fsc' mount option through NFS automounts of various types.

This is now required as commit:

	Author: Trond Myklebust <Trond.Myklebust@netapp.com>
	Date:   Mon Jun 22 15:09:14 2009 -0400

	NFSv4: Replace nfs4_path_walk() with VFS path lookup in a private namespace

uses VFS-driven automounting to reach all submounts barring the root, thus
preventing fscaching from being enabled on any submount other than the root.

This patch gets around that by propagating the NFS_OPTION_FSCACHE flag across
automounts.  If a uniquifier is supplied to a mount then this is propagated to
all automounts of that mount too.

Subject: hwmon: (adm1031) Add sysfs files for temperature offsets

The ADM1030/ADM1031 chips have temperature offset registers, for both the
local and remote temperature sensors. Following the example set forth in
the LM90/ADM1032 driver, expose the offset registers to userspace.

-Kernel driver fscher
-====================
-
-Supported chips:
-  * Fujitsu-Siemens Hermes chip
-    Prefix: 'fscher'
-    Addresses scanned: I2C 0x73
-
-Authors:
-        Reinhard Nissl <rnissl@gmx.de> based on work
-        from Hermann Jung <hej@odn.de>,
-        Frodo Looijaard <frodol@dds.nl>,
-        Philip Edelbrock <phil@netroedge.com>
-
-Description
------------
-
-This driver implements support for the Fujitsu-Siemens Hermes chip. It is
-described in the 'Register Set Specification BMC Hermes based Systemboard'
-from Fujitsu-Siemens.
-
-The Hermes chip implements a hardware-based system management, e.g. for
-controlling fan speed and core voltage. There is also a watchdog counter on
-the chip which can trigger an alarm and even shut the system down.
-
-The chip provides three temperature values (CPU, motherboard and
-auxiliary), three voltage values (+12V, +5V and battery) and three fans
-(power supply, CPU and auxiliary).
-
-Temperatures are measured in degrees Celsius. The resolution is 1 degree.
-
-Fan rotation speeds are reported in RPM (rotations per minute). The value
-can be divided by a programmable divider (1, 2 or 4) which is stored on
-the chip.
-
-Voltage sensors (also known as "in" sensors) report their values in volts.
-
-All values are reported as final values from the driver. There is no need
-for further calculations.
-
-
-Detailed description
---------------------
-
-Below you'll find a single line description of all the bit values. With
-this information, you're able to decode e. g. alarms, wdog, etc. To make
-use of the watchdog, you'll need to set the watchdog time and enable the
-watchdog. After that it is necessary to restart the watchdog time within
-the specified period of time, or a system reset will occur.

-Limitations
------------
-
-* Measuring fan speed
-It seems that the chip counts "ripples" (typical fans produce 2 ripples per
-rotation while VERAX fans produce 18) in a 9-bit register. This register is
-read out every second, then the ripple prescaler (2, 4 or 8) is applied and
-the result is stored in the 8 bit output register. Due to the limitation of
-the counting register to 9 bits, it is impossible to measure a VERAX fan
-properly (even with a prescaler of 8). At its maximum speed of 3500 RPM the
-fan produces 1080 ripples per second which causes the counting register to
-overflow twice, leading to only 186 RPM.
-
-* Measuring input voltages
-in2 ("battery") reports the voltage of the onboard lithium battery and not
-+3.3V from the power supply.
-
-* Undocumented features
-Fujitsu-Siemens Computers has not documented all features of the chip so
-far. Their software, System Guard, shows that there are a still some
-features which cannot be controlled by this implementation.

-
-	  If you say yes here you get support for Fujitsu Siemens

-
-	  This driver can also be built as a module.  If so, the module

Fix Atom CPUs support. Intel documents TjMax at 90 degrees C but
some Atoms may have 125 degrees C (this is undocumented speculation).

Subject: hwmon: (coretemp) Add support for Penryn mobile CPUs

Following patch adds support for mobile Penryn CPUs. Intel documents this
poorly. I asked the Coretemp author for some help. This is totally untested and
may not work. Please test!

Subject: hwmon: (ltc4215) Clear faults at startup

When power is applied to the ltc4215 chip it sometimes reports spurious
faults. The faults are not yet exposed via sysfs, however it may be useful
for userspace to read the fault register directly with the i2cget command.
Clear the fault register when the driver is installed so userspace doesn't
have to worry about spurious fault indications.

Subject: cpumask: remove dangerous CPU_MASK_ALL_PTR

(Thanks to Al Viro for reminding me of this, via Ingo)

CPU_MASK_ALL is the (deprecated) "all bits set" cpumask, defined as so:

	#define CPU_MASK_ALL (cpumask_t) { { ... } }

Taking the address of such a temporary is questionable at best,
unfortunately 321a8e9d (cpumask: add CPU_MASK_ALL_PTR macro) added
CPU_MASK_ALL_PTR:

	#define CPU_MASK_ALL_PTR (&CPU_MASK_ALL)

Which formalizes this practice.  One day gcc could bite us over this
usage (though we seem to have gotten away with it so far).

Now all callers are removed, we kill it.

So replace everywhere which used &CPU_MASK_ALL or CPU_MASK_ALL_PTR
with the modern "cpu_all_mask" (a real struct cpumask *), and remove
CPU_MASK_ALL_PTR altogether.

Subject: cpumask: remove unused mask field from struct irqaction.

Up until 1.1.83, the primitive human tribes used struct sigaction for
interrupts.  The sa_mask field was overloaded to hold a pointer to the
name.

When someone created the new "struct irqaction" they carried across
the "mask" field as a kind of ancestor worship: the fact that it was
unused makes clear its spiritual significance.

Subject: cpumask: arch_send_call_function_ipi_mask: alpha

We're weaning the core code off handing cpumask's around on-stack.
This introduces arch_send_call_function_ipi_mask().

We also take the chance to wean the send_ipi_message off the
obsolescent for_each_cpu_mask(): making it take a pointer seemed the
most natural way to do this.

From f063ea02fba5782099b6730d5733ee44638df8f9 Mon Sep 17 00:00:00 2001
From: Rusty Russell <rusty@rustcorp.com.au>
Date: Thu, 24 Sep 2009 09:34:45 -0600
Subject: cpumask: arch_send_call_function_ipi_mask: powerpc

We're weaning the core code off handing cpumask's around on-stack.
This introduces arch_send_call_function_ipi_mask(), and by defining
it, the old arch_send_call_function_ipi is defined by the core code.

Subject: cpumask: use mm_cpumask() wrapper: mn10300

Makes code futureproof against the impending change to mm->cpu_vm_mask
(to be a pointer).

It's also a chance to use the new cpumask_ ops which take a pointer
(the older ones are deprecated, but there's no hurry for arch code).

Also change the actual arg name here to "mm" (which it is), not "task".

Subject: cpumask: remove unused deprecated functions, avoid accusations of
 insanity

We're not forcing removal of the old cpu_ functions, but we might as
well delete the now-unused ones.

Especially CPUMASK_ALLOC and friends.  I actually got a phone call (!)
from a hacker who thought I had introduced them as the new cpumask
API.  He seemed bewildered that I had lost all taste.

Subject: cpumask: Move deprecated functions to end of header.

The new ones have pretty kerneldoc.  Move the old ones to the end to
avoid confusing people.

 /*
  * Cpumasks provide a bitmap suitable for representing the
- * set of CPU's in a system, one bit position per CPU number.
- *
- * The new cpumask_ ops take a "struct cpumask *"; the old ones
- * use cpumask_t.
- *
- * See detailed comments in the file linux/bitmap.h describing the
- * data type on which these cpumasks are based.
- *
- * For details of cpumask_scnprintf() and cpumask_parse_user(),
- * see bitmap_scnprintf() and bitmap_parse_user() in lib/bitmap.c.
- * For details of cpulist_scnprintf() and cpulist_parse(), see
- * bitmap_scnlistprintf() and bitmap_parselist(), also in bitmap.c.
- *
- * . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
- * Note: The alternate operations with the suffix "_nr" are used
- *       to limit the range of the loop to nr_cpu_ids instead of
- *       NR_CPUS when NR_CPUS > 64 for performance reasons.
- *       If NR_CPUS is <= 64 then most assembler bitmask
- *       operators execute faster with a constant range, so
- *       the operator will continue to use NR_CPUS.
- *
- *       Another consideration is that nr_cpu_ids is initialized
- *       to NR_CPUS and isn't lowered until the possible cpus are
- *       discovered (including any disabled cpus).  So early uses
- *       will span the entire range of NR_CPUS.
- * . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
- *
- * The obsolescent cpumask operations are:
- *
- * void cpu_set(cpu, mask)		turn on bit 'cpu' in mask
- * void cpu_clear(cpu, mask)		turn off bit 'cpu' in mask
- * void cpus_setall(mask)		set all bits
- * void cpus_clear(mask)		clear all bits
- * int cpu_isset(cpu, mask)		true iff bit 'cpu' set in mask
- * int cpu_test_and_set(cpu, mask)	test and set bit 'cpu' in mask
- *
- * int cpus_and(dst, src1, src2)	dst = src1 & src2  [intersection]
- * void cpus_or(dst, src1, src2)	dst = src1 | src2  [union]
- * void cpus_xor(dst, src1, src2)	dst = src1 ^ src2
- * int cpus_andnot(dst, src1, src2)	dst = src1 & ~src2
- *
- * int cpus_equal(mask1, mask2)		Does mask1 == mask2?
- * int cpus_intersects(mask1, mask2)	Do mask1 and mask2 intersect?
- * int cpus_subset(mask1, mask2)	Is mask1 a subset of mask2?
- * int cpus_empty(mask)			Is mask empty (no bits sets)?
- * int cpus_weight(mask)		Hamming weigh - number of set bits
- *
- * void cpus_shift_left(dst, src, n)	Shift left
- *
- * int first_cpu(mask)			Number lowest set bit, or NR_CPUS
- * int next_cpu(cpu, mask)		Next cpu past 'cpu', or NR_CPUS
- *
- * cpumask_t cpumask_of_cpu(cpu)	Return cpumask with bit 'cpu' set
- *					(can be used as an lvalue)
- * CPU_MASK_ALL				Initializer - all bits set
- * CPU_MASK_NONE			Initializer - no bits set
- * unsigned long *cpus_addr(mask)	Array of unsigned long's in mask
- *
- * int cpumask_scnprintf(buf, len, mask) Format cpumask for printing
- * int cpumask_parse_user(ubuf, ulen, mask)	Parse ascii string as cpumask
- * int cpulist_scnprintf(buf, len, mask) Format cpumask as list for printing
- * int cpulist_parse(buf, map)		Parse ascii string as cpulist
- *
- * for_each_cpu_mask(cpu, mask)		for-loop cpu over mask using NR_CPUS
- * for_each_cpu_mask_nr(cpu, mask)	for-loop cpu over mask using nr_cpu_ids
- *
- * int num_online_cpus()		Number of online CPUs
- * int num_possible_cpus()		Number of all possible CPUs
- * int num_present_cpus()		Number of present CPUs
- *
- * int cpu_online(cpu)			Is some cpu online?
- * int cpu_possible(cpu)		Is some cpu possible?
- * int cpu_present(cpu)			Is some cpu present (can schedule)?
- *
- * int any_online_cpu(mask)		First online cpu in mask
- *
- * for_each_possible_cpu(cpu)		for-loop cpu over cpu_possible_map
- * for_each_online_cpu(cpu)		for-loop cpu over cpu_online_map
- * for_each_present_cpu(cpu)		for-loop cpu over cpu_present_map
- *
- * Subtlety:
- * 1) The 'type-checked' form of cpu_isset() causes gcc (3.3.2, anyway)
- *    to generate slightly worse code.  Note for example the additional
- *    40 lines of assembly code compiling the "for each possible cpu"
- *    loops buried in the disk_stat_read() macros calls when compiling
- *    drivers/block/genhd.c (arch i386, CONFIG_SMP=y).  So use a simple
- *    one-line #define for cpu_isset(), instead of wrapping an inline
- *    inside a macro, the way we do the other calls.
+ * set of CPU's in a system, one bit position per CPU number.  In general,
+ * only nr_cpu_ids (<= NR_CPUS) bits are valid.

Subject: virtio_net: skb_orphan() and nf_reset() in xmit path.

The complex transmit free logic was introduced to avoid hangs on
removing the ip_conntrack module and also because drivers aren't
generally supposed to keep stale skbs for unbounded times.

After some debate, it was decided that while doing skb_orphan()
generally is a rat's nest, we can do it in this driver.  Following
patches take advantage of this.

Subject: virtio_net: return NETDEV_TX_BUSY instead of queueing an extra skb.

This effectively reverts 99ffc696d10b28580fe93441d627cf290ac4484c
"virtio: wean net driver off NETDEV_TX_BUSY".

The complexity of queuing an skb (setting a tasklet to re-xmit) is
questionable, especially once we get rid of the other reason for the
tasklet in the next patch.

If the skb won't fit in the tx queue, just return NETDEV_TX_BUSY.
This is frowned upon, so a followup patch uses a more complex solution.

Subject: virtio_net: don't free buffers in xmit ring

The virtio_net driver is complicated by the two methods of freeing old
xmit buffers (in addition to freeing old ones at the start of the xmit
path).

The original code used a 1/10 second timer attached to xmit_free(),
reset on every xmit.  Before we orphaned skbs on xmit, the
transmitting userspace could block with a full socket until the timer
fired, the skb destructor was called, and they were re-woken.

So we added the VIRTIO_F_NOTIFY_ON_EMPTY feature: supporting devices
send an interrupt (even if normally suppressed) on an empty xmit ring
which makes us schedule xmit_tasklet().  This was a benchmark win.

Unfortunately, VIRTIO_F_NOTIFY_ON_EMPTY makes quite a lot of work: a
host which is faster than the guest will fire the interrupt every xmit
packet (slowing the guest down further).  Attempting mitigation in the
host adds overhead of userspace timers (possibly with the additional
pain of signals), and risks increasing latency anyway if you get it
wrong.

In practice, this effect was masked by benchmarks which take advantage
of GSO (with its inherent transmit batching), but it's still there.

Now we orphan xmitted skbs, the pressure is off: remove both paths and
no longer request VIRTIO_F_NOTIFY_ON_EMPTY.  Note that the current
QEMU will notify us even if we don't negotiate this feature (legal,
but suboptimal); a patch is outstanding to improve that.

Move the skb_orphan/nf_reset to after we've done the send and notified
the other end, for a slight optimization.

Subject: virtio_net: avoid (most) NETDEV_TX_BUSY by stopping queue early.

Now we can tell the theoretical capacity remaining in the output
queue, virtio_net can waste entries by stopping the queue early.

It doesn't work in the case of indirect buffers and kmalloc failure,
but that's rare (we could drop the packet in that case, but other
drivers return TX_BUSY for similar reasons).

For the record, I think this patch reflects poorly on the linux
network API.

Subject: Btrfs: fix errors handling cached state in set/clear_extent_bit

Both set and clear_extent_bit allow passing a cached
state struct to reduce rbtree search times.  clear_extent_bit
was improperly bypassing some of the checks around making sure
the extent state fields were correct for a given operation.

The fix used here (from Yan Zheng) is to use the hit_next
goto target instead of jumping all the way down to start clearing
bits without making sure the cached state was exactly correct
for the operation we were doing.

This also fixes up the setting of the start variable for both
ops in the case where we find an overlapping extent that
begins before the range we want to change.  In both cases
we were incorrectly going backwards from the original
requested change.

Subject: Btrfs: Fix test_range_bit for whole file extents

If test_range_bit finds an extent that goes all the way to (u64)-1, it
can incorrectly wrap the u64 instead of treaing it like the end of
the address space.

This just adds a check for the highest possible offset so we don't wrap.

Subject: Btrfs: fix releasepage to avoid unlocking extents we haven't locked

During releasepage, we try to drop any extent_state structs for the
bye offsets of the page we're releaseing.  But the code was incorrectly
telling clear_extent_bit to delete the state struct unconditionallly.

Normally this would be fine because we have the page locked, but other
parts of btrfs will lock down an entire extent, the most common place
being IO completion.

releasepage was deleting the extent state without first locking the extent,
which may result in removing a state struct that another process had
locked down.  The fix here is to leave the NODATASUM and EXTENT_LOCKED
bits alone in releasepage.

Subject: intel-iommu: Make "Unknown DMAR structure" message more informative

We might as well print the type of the DMAR structure we don't know how
to handle when skipping it.  Then someone getting this message has a
chance of telling whether the structure is just bogus, or if there
really is something valid that the kernel doesn't know how to handle.

Subject: Revert "kmod: fix race in usermodehelper code"

This reverts commit c02e3f361c7 ("kmod: fix race in usermodehelper code")

The patch is wrong.  UMH_WAIT_EXEC is called with VFORK what ensures
that the child finishes prior returing back to the parent.  No race.

In fact, the patch makes it even worse because it does the thing it
claims not do:

 - It calls ->complete() on UMH_WAIT_EXEC

 - the complete() callback may de-allocated subinfo as seen in the
   following call chain:

    [<c009f904>] (__link_path_walk+0x20/0xeb4) from [<c00a094c>] (path_walk+0x48/0x94)
    [<c00a094c>] (path_walk+0x48/0x94) from [<c00a0a34>] (do_path_lookup+0x24/0x4c)
    [<c00a0a34>] (do_path_lookup+0x24/0x4c) from [<c00a158c>] (do_filp_open+0xa4/0x83c)
    [<c00a158c>] (do_filp_open+0xa4/0x83c) from [<c009ba90>] (open_exec+0x24/0xe0)
    [<c009ba90>] (open_exec+0x24/0xe0) from [<c009bfa8>] (do_execve+0x7c/0x2e4)
    [<c009bfa8>] (do_execve+0x7c/0x2e4) from [<c0026a80>] (kernel_execve+0x34/0x80)
    [<c0026a80>] (kernel_execve+0x34/0x80) from [<c004b514>] (____call_usermodehelper+0x130/0x148)
    [<c004b514>] (____call_usermodehelper+0x130/0x148) from [<c0024858>] (kernel_thread_exit+0x0/0x8)

   and the path pointer was NULL.  Good that ARM's kernel_execve()
   doesn't check the pointer for NULL or else I wouldn't notice it.

The only race there might be is with UMH_NO_WAIT but it is too late for
me to investigate it now.  UMH_WAIT_PROC could probably also use VFORK
and we could save one exec.  So the only race I see is with UMH_NO_WAIT
and recent scheduler changes where the child does not always run first
might have trigger here something but as I said, it is late....

Subject: headers: utsname.h redux

* remove asm/atomic.h inclusion from linux/utsname.h --
   not needed after kref conversion
 * remove linux/utsname.h inclusion from files which do not need it

NOTE: it looks like fs/binfmt_elf.c do not need utsname.h, however
due to some personality stuff it _is_ needed -- cowardly leave ELF-related
headers and files alone.

From 254be490f257fc3f76ca5f869ac8d107b3827025 Mon Sep 17 00:00:00 2001
From: Hendrik Brueckner <brueckner@linux.vnet.ibm.com>
Date: Thu, 27 Aug 2009 01:45:39 +0000
Subject: hvc_console: Provide (un)locked version for hvc_resize()

Rename the locking free hvc_resize() function to __hvc_resize() and
provide an inline function that locks the hvc_struct and calls
__hvc_resize().

The rationale for this patch is that virtio_console calls the hvc_resize()
function without locking the hvc_struct. So it needs to call the lock
itself.

According to naming rules, the unlocked version is renamed and
prefixed with "__".
References to unlocked function calls in hvc back-ends has been updated.

Subject: powerpc: Check for unsupported relocs when using CONFIG_RELOCATABLE

When using CONFIG_RELOCATABLE, we build the kernel as a position
independent executable. The kernel then uses a little bit of relocation
code to relocate itself. That code only deals with R_PPC64_RELATIVE
relocations though. If for some reason you use assembly constructs
such as LOAD_REG_IMMEDIATE() to load the address of a symbol, you'll
generate different kinds of relocations that won't be processed properly
and bad things will happen. (We have 2 such bugs today).

The perl script tries to filter out "known" bad ones. It's possible
that we are missing some in the case of a weak function that nobody
implements, we'll see if we get false positive and fix it.

Subject: powerpc: Rename get_dma_direct_offset get_dma_offset

The former is no longer really accurate with the swiotlb case now
a possibility.  I also move it into dma-mapping.h - it no longer
needs to be in dma.c, and there are about to be some more accessors
that should all end up in the same place.  A comment is added to
indicate that this function is not used in configs where there is no
simple dma offset, such as the iommu case.

Sometimes this is used to hold a simple offset, and sometimes
it is used to hold a pointer.  This patch changes it to a union containing
void * and dma_addr_t.  get/set accessors are also provided, because it was
getting a bit ugly to get to the actual data.

Subject: powerpc: Move 64bit heap above 1TB on machines with 1TB segments

If we are using 1TB segments and we are allowed to randomise the heap, we can
put it above 1TB so it is backed by a 1TB segment. Otherwise the heap will be
in the bottom 1TB which always uses 256MB segments and this may result in a
performance penalty.

This functionality is disabled when heap randomisation is turned off:

echo 1 > /proc/sys/kernel/randomize_va_space

which may be useful when trying to allocate the maximum amount of 16M or 16G
pages.

On a microbenchmark that repeatedly touches 32GB of memory with a stride of
256MB + 4kB (designed to stress 256MB segments while still mapping nicely into
the L1 cache), we see the improvement:

Force malloc to use heap all the time:
# export MALLOC_MMAP_MAX_=0 MALLOC_TRIM_THRESHOLD_=-1

Disable heap randomization:
# echo 1 > /proc/sys/kernel/randomize_va_space
# time ./test
12.51s

Enable heap randomization:
# echo 2 > /proc/sys/kernel/randomize_va_space
# time ./test
1.70s

perf_counter uses arch_vma_name() to detect a vdso region which in turn uses
current->mm->context.vdso_base. We need to initialise this before doing
the mmap or else we fail to detect the vdso.

Subject: powerpc: Increase NODES_SHIFT on 64bit from 4 to 8

Some System p configurations can already have more than 16 nodes so we
need to increase NODES_SHIFT. I chose 256 to give us some room to grow in the
future, although we can look at something smaller if the memory bloat is
considered too much.

Unless we clamp MAX_ACTIVE_REGIONS we end up with 300kB of extra bloat in
early_node_map in mm/page_alloc.c:

< 6144   early_node_map
> 307200 early_node_map

due to:

    #if MAX_NUMNODES >= 32
      /* If there can be many nodes, allow up to 50 holes per node */
      #define MAX_ACTIVE_REGIONS (MAX_NUMNODES*50)
    #else
      /* By default, allow up to 256 distinct regions */
    #define MAX_ACTIVE_REGIONS 256

Since our memory is mostly contiguous it seems reasonable to keep this
at 256 for now. I also set 32bit to 32 to save space (is there any chance
a 32bit system will have more than 32 discontiguous memory ranges?).

Even with that fixed we have a few data structures that grow:

< 896   bootmem_node_data
> 14336 bootmem_node_data

< 1280  node_devices
> 20480 node_devices

< 25088 kmalloc_caches
> 59648 kmalloc_caches

< 1632  hstates
> 21792 hstates

Subject: powerpc: Fix ibm,client-architecture-support printout

On machines without the ibm,client-architecture-support call we were missing a
newline. We may as well print the full name in all its glory too - its
ibm,client-architecture-support, not ibm,client-architecture as I mistakenly
wrote (a name only an IBM architect could love).

For my penance I will write out ibm,client-architecture-support 100 times.

Before:

Calling ibm,client-architecture...command line: root=/dev/sda6 console=hvc0  quiet

After:

Calling ibm,client-architecture-support... not implemented
command line: root=/dev/sda6 console=hvc0

Subject: powerpc/mm: Fix 40x and 8xx vs. _PAGE_SPECIAL

The test to check whether we have _PAGE_SPECIAL defined is broken,
since we always define it, just not always to a meaninful value :-)

That broke 8xx and 40x under some circumstances.

This fixes it by adding _PAGE_SPECIAL for both of these since they
had a free PTE bit, and removing the condition around advertising
it.

Subject: powerpc/4xx: Fix erroneous xmon warning on PowerPC 4xx

The xmon code relies on MSR_RI being non-zero to indicate that an exception
is recoverable.  If it is not, it prints a warning message.  However, the
PowerPC 4xx cores do not have an MSR_RI bit and this warning is produced for
every xmon event.

This introduces an unrecoverable_excp function to determine if an exception
is recoverable or not.  This gets rid of the erroneous warnings on 4xx.

Subject: powerpc/8xx: Fix regression introduced by cache coherency rewrite

After upgrading to the latest kernel on my mpc875 userspace started
running incredibly slow (hours to get to a shell, even!).
I tracked it down to commit 8d30c14cab30d405a05f2aaceda1e9ad57800f36,
that patch removed a work-around for the 8xx. Adding it
back makes my problem go away.

Subject: Audit: reorganize struct audit_watch to save 8 bytes

pahole showed that struct audit_watch had two holes:

struct audit_watch {
        atomic_t                   count;                /*     0     4 */

        /* XXX 4 bytes hole, try to pack */

        char *                     path;                 /*     8     8 */
        dev_t                      dev;                  /*    16     4 */

        /* XXX 4 bytes hole, try to pack */

        long unsigned int          ino;                  /*    24     8 */
        struct audit_parent *      parent;               /*    32     8 */
        struct list_head           wlist;                /*    40    16 */
        struct list_head           rules;                /*    56    16 */
        /* --- cacheline 1 boundary (64 bytes) was 8 bytes ago --- */

        /* size: 72, cachelines: 2, members: 7 */
        /* sum members: 64, holes: 2, sum holes: 8 */
        /* last cacheline: 8 bytes */
};      /* definitions: 1 */

by moving dev after count we save 8 bytes,  actually improving cacheline
usage.  There are typically very few of these in the kernel so it won't be
a large savings, but it's a good thing no matter what.

Subject: Audit: send signal info if selinux is disabled

Audit will not respond to signal requests if selinux is disabled since it is
unable to translate the 0 sid from the sending process to a context.  This
patch just doesn't send the context info if there isn't any.

Subject: lsm: Use a compressed IPv6 string format in audit events

Currently the audit subsystem prints uncompressed IPv6 addresses which not
only differs from common usage but also results in ridiculously large audit
strings which is not a good thing.  This patch fixes this by simply converting
audit to always print compressed IPv6 addresses.

Old message example:

 audit(1253576792.161:30): avc:  denied  { ingress } for
  saddr=0000:0000:0000:0000:0000:0000:0000:0001 src=5000
  daddr=0000:0000:0000:0000:0000:0000:0000:0001 dest=35502 netif=lo
  scontext=system_u:object_r:unlabeled_t:s15:c0.c1023
  tcontext=system_u:object_r:lo_netif_t:s0-s15:c0.c1023 tclass=netif

New message example:

 audit(1253576792.161:30): avc:  denied  { ingress } for
  saddr=::1 src=5000 daddr=::1 dest=35502 netif=lo
  scontext=system_u:object_r:unlabeled_t:s15:c0.c1023
  tcontext=system_u:object_r:lo_netif_t:s0-s15:c0.c1023 tclass=netif

Subject: microblaze: Support simpleImage.dts make target

Instead of remembering to specify DTB= on the make commandline, this commit
allows the much friendlier make simpleImage.<dts>
where <dts>.dts is expected to be found in arch/microblaze/boot/dts/
The resulting vmlinux, with the compiled DTS linked in, will be copied to
boot/simpleImage.<dts>

This mirrors the same functionality as on PowerPC,
albeit achieving it in a slightly different way.

+ strip simpleImage file
The size of output file is very similar to linux.bin.

vmlinux - full elf without fdt blob
simpleImage.<dtb name>.unstrip - full elf with fdt blob
simpleImage.<dtb name> - stripped elf with fdt blob

Add symlink to generic system.dts in platform folder

Subject: sh: Handle unaligned 16-bit instructions on SH-2A.

This adds some sanity checking in the unaligned instruction handler to
verify the instruction size, which enables basic support for 16-bit
fixups on SH-2A parts.

Subject: sh: Fix up uninitialized variable use caught by gcc 4.4.

In the unaligned kernel exception fixup case the printk() was ordered
before the copy_from_user(), resulting in a nonsensical instruction
value. This fixes up the ordering properly.

Subject: x86: Reduce verbosity of "TSC is reliable" message

On modern systems, the kernel prints the message

    Skipping synchronization checks as TSC is reliable.

once for every non-boot CPU.

This gets kind of ridiculous on huge systems; for example, on a
64-thread system I was lucky enough to get:

    $ dmesg | grep 'TSC is reliable' | wc
         63     567    4221

There's no point to doing this for every CPU, since the code is
just checking the boot CPU anyway, so change this to a
printk_once() to make the message appears only once.

Subject: x86: Reduce verbosity of "PAT enabled" kernel message

On modern systems, the kernel prints the message

    x86 PAT enabled: cpu 0, old 0x7040600070406, new 0x7010600070106

once for every CPU.

This gets kind of ridiculous on huge systems; for example, on a
64-thread system I was lucky enough to get:

    dmesg| grep 'PAT enabled' | wc
         64     704    5174

There is already a BUG() if non-boot CPUs have PAT capabilities
that don't match the boot CPU, so just print the message on the
boot CPU. (I kept the print after the wrmsrl() that enables PAT,
so that the log output continues to mean that the system survived
enabling PAT on the boot CPU)

Subject: libfs: make simple_read_from_buffer conventional

Impact: have simple_read_from_buffer conform to standards

It was brought to my attention by Andrew Morton, Theodore Tso, and H.
Peter Anvin that a read from userspace should only return -EFAULT if
nothing was actually read.

Looking at the simple_read_from_buffer I noticed that this function does
not conform to that rule.  This patch fixes that function.

Subject: vfs: split generic_forget_inode() so that hugetlbfs does not have to
 copy it

Hugetlbfs needs to do special things instead of truncate_inode_pages().
 Currently, it copied generic_forget_inode() except for
truncate_inode_pages() call which is asking for trouble (the code there
isn't trivial).  So create a separate function generic_detach_inode()
which does all the list magic done in generic_forget_inode() and call
it from hugetlbfs_forget_inode().

Subject: vfs: optimization for touch_atime()

Some benchmark testing shows touch_atime to be high up in profile logs for
IO intensive workloads.  Most likely that's due to the lock in
mnt_want_write().  Unfortunately touch_atime first takes the lock, and
then does all the other tests that could avoid atime updates (like noatime
or relatime).

Do it the other way round -- first try to avoid the update and only then
if that didn't succeed take the lock.  That works because none of the
atime avoidance tests rely on locking.

This also eliminates a goto.

Subject: vfs: optimize touch_time() too

Do a similar optimization as earlier for touch_atime.  Getting the lock in
mnt_get_write is relatively costly, so try all avenues to avoid it first.

This patch is careful to still only update inode fields inside the lock
region.

This didn't show up in benchmarks, but it's easy enough to do.

seq_path_root() is returning a return value of successful __d_path()

This is not a bug so far because nobody is using return value of
seq_path_root().

Subject: vfs: explicitly cast s_maxbytes in fiemap_check_ranges

If fiemap_check_ranges is passed a large enough value, then it's
possible that the value would be cast to a signed value for comparison
against s_maxbytes when we change it to loff_t. Make sure that doesn't
happen by explicitly casting s_maxbytes to an unsigned value for the
purposes of comparison.

Subject: vfs: change sb->s_maxbytes to a loff_t

sb->s_maxbytes is supposed to indicate the maximum size of a file that can
exist on the filesystem.  It's declared as an unsigned long long.

Even if a filesystem has no inherent limit that prevents it from using
every bit in that unsigned long long, it's still problematic to set it to
anything larger than MAX_LFS_FILESIZE.  There are places in the kernel
that cast s_maxbytes to a signed value.  If it's set too large then this
cast makes it a negative number and generally breaks the comparison.

Change s_maxbytes to be loff_t instead.  That should help eliminate the
temptation to set it too large by making it a signed value.

Also, add a warning for couple of releases to help catch filesystems that
set s_maxbytes too large.  Eventually we can either convert this to a
BUG() or just remove it and in the hope that no one will get it wrong now
that it's a signed value.

Subject: vfs: seq_file: add helpers for data filling

Add two helpers that allow access to the seq_file's own buffer, but
hide the internal details of seq_files.

This allows easier implementation of special purpose filling
functions.  It also cleans up some existing functions which duplicated
the seq_file logic.

Make these inline functions in seq_file.h, as suggested by Al.

Subject: exofs: remove BKL from super operations

the two places inside exofs that where taking the BKL were:
exofs_put_super() - .put_super
and
exofs_sync_fs() - which is .sync_fs and is also called from
                  .write_super.

Now exofs_sync_fs() is protected from itself by also taking
the sb_lock.

exofs_put_super() directly calls exofs_sync_fs() so there is no
danger between these two either.

In anyway there is absolutely nothing dangerous been done
inside exofs_sync_fs().

Unless there is some subtle race with the actual lifetime of
the super_block in regard to .put_super and some other parts
of the VFS. Which is highly unlikely.

Subject: freeze_bdev: kill bd_mount_sem

Now that we have the freeze count there is not much reason for bd_mount_sem
anymore.  The actual freeze/thaw operations are serialized using the
bd_fsfreeze_mutex, and the only other place we take bd_mount_sem is
get_sb_bdev which tries to prevent mounting a filesystem while the block
device is frozen.  Instead of add a check for bd_fsfreeze_count and
return -EBUSY if a filesystem is frozen.  While that is a change in user
visible behaviour a failing mount is much better for this case rather
than having the mount process stuck uninterruptible for a long time.

Subject: freeze_bdev: grab active reference to frozen superblocks

Currently we held s_umount while a filesystem is frozen, despite that we
might return to userspace and unlock it from a different process.  Instead
grab an active reference to keep the file system busy and add an explicit
check for frozen filesystems in remount and reject the remount instead
of blocking on s_umount.

Add a new get_active_super helper to super.c for use by freeze_bdev that
grabs an active reference to a superblock from a given block device.

From 6d729e44a55547c009d7a87ea66bff21a8e0afea Mon Sep 17 00:00:00 2001

Subject: fs: Make unload_nls() NULL pointer safe

Most call sites of unload_nls() do:
	if (nls)
		unload_nls(nls);

Check the pointer inside unload_nls() like we do in kfree() and
simplify the call sites.

Subject: x86: Remove redundant non-NUMA topology functions

arch/x86/include/asm/topology.h declares inline fns cpu_to_node and
cpumask_of_node for !NUMA, even though they are then declared as
macros by asm-generic/topology.h, which is #included just below.

The macros (which are the same) end up being used; these functions
are just confusing.

Subject: fs: fix overflow in sys_mount() for in-kernel calls

sys_mount() reads/copies a whole page for its "type" parameter.  When
do_mount_root() passes a kernel address that points to an object which is
smaller than a whole page, copy_mount_options() will happily go past this
memory object, possibly dereferencing "wild" pointers that could be in any
state (hence the kmemcheck warning, which shows that parts of the next
page are not even allocated).

(The likelihood of something going wrong here is pretty low -- first of
all this only applies to kernel calls to sys_mount(), which are mostly
found in the boot code.  Secondly, I guess if the page was not mapped,
exact_copy_from_user() _would_ in fact handle it correctly because of its
access_ok(), etc.  checks.)

But it is much nicer to avoid the dubious reads altogether, by stopping as
soon as we find a NUL byte.  Is there a good reason why we can't do
something like this, using the already existing strndup_from_user()?

[akpm@linux-foundation.org: make copy_mount_string() static]
[AV: fix compat mount breakage, which involves undoing akpm's change above]

From 25d9e2d15286281ec834b829a4aaf8969011f1cd Mon Sep 17 00:00:00 2001
From: "npiggin@suse.de" <npiggin@suse.de>
Date: Fri, 21 Aug 2009 02:35:05 +1000
Subject: truncate: new helpers

Introduce new truncate helpers truncate_pagecache and inode_newsize_ok.
vmtruncate is also consolidated from mm/memory.c and mm/nommu.c and
into mm/truncate.c.

From c08d3b0e33edce28e9cfa7b64f7fe5bdeeb29248 Mon Sep 17 00:00:00 2001
From: "npiggin@suse.de" <npiggin@suse.de>
Date: Fri, 21 Aug 2009 02:35:06 +1000
Subject: truncate: use new helpers

Update some fs code to make use of new helper functions introduced
in the previous patch. Should be no significant change in behaviour
(except CIFS now calls send_sig under i_lock, via inode_newsize_ok).

Subject: Btrfs: check size of inode backref before adding hardlink

For every hardlink in btrfs, there is a corresponding inode back
reference. All inode back references for hardlinks in a given
directory are stored in single b-tree item. The size of b-tree item
is limited by the size of b-tree leaf, so we can only create limited
number of hardlinks to a given file in a directory.

The original code lacks of the check, it oops if the number of
hardlinks goes over the limit. This patch fixes the issue by adding
check to btrfs_link and btrfs_rename.

Subject: Btrfs: don't rename file into dummy directory

A recent change enforces only one access point to each subvolume. The first
directory entry (the one added when the subvolume/snapshot was created) is
treated as valid access point, all other subvolume links are linked to dummy
empty directories. The dummy directories are temporary inodes that only in
memory, so we can not rename file into them.

The extent relocation code copy file extents one by one when
relocating data block group. This is inefficient if file
extents are small. This patch makes the relocation code copy
file extents in clusters. So we can can make better use of

Fix these warnings:

  fujitsu-laptop.c:(.exit.text+0xbe53): undefined reference to `led_classdev_unregister'

It happens because the new INPUT_WINBOND_CIR driver relies on new-leds
infrastructure - but does not select it in drivers/input/misc/Kconfig.
But it selects LEDS_CLASS, which confuses a number of other drivers into
thinking that all the leds infrastructure is in place.

Fix this by selecting NEW_LEDS as well, like similar drivers do.

Eventually, this whole leds infrastructure complexity should be
cleaned up, it's been going on for years.

Subject: ksm: change default values to better fit into mainline kernel

Now that ksm is in mainline it is better to change the default values to
better fit to most of the users.

This patch change the ksm default values to be:

	ksm_thread_pages_to_scan = 100 (instead of 200)
	ksm_thread_sleep_millisecs = 20 (like before)
	ksm_run = KSM_RUN_STOP (instead of KSM_RUN_MERGE - meaning ksm is
	                        disabled by default)
	ksm_max_kernel_pages = nr_free_buffer_pages / 4 (instead of 2046)

The important aspect of this patch is: it disables ksm by default, and sets
the number of the kernel_pages that can be allocated to be a reasonable
number.

Subject: hugetlbfs: do not call user_shm_lock() for MAP_HUGETLB fix

Commit 6bfde05bf5c ("hugetlbfs: allow the creation of files suitable for
MAP_PRIVATE on the vfs internal mount") altered can_do_hugetlb_shm() to
check if a file is being created for shared memory or mmap().  If this
returns false, we then unconditionally call user_shm_lock() triggering a
warning.  This block should never be entered for MAP_HUGETLB.  This
patch partially reverts the problem and fixes the check.

Subject: time: add function to convert between calendar time and broken-down
 time for universal use

There are many similar code in kernel for one object: convert time between
calendar time and broken-down time.

Here is some source I found:
  fs/ncpfs/dir.c
  fs/smbfs/proc.c
  fs/fat/misc.c
  fs/udf/udftime.c
  fs/cifs/netmisc.c
  net/netfilter/xt_time.c
  drivers/scsi/ips.c
  drivers/input/misc/hp_sdc_rtc.c
  drivers/rtc/rtc-lib.c
  arch/ia64/hp/sim/boot/fw-emu.c
  arch/m68k/mac/misc.c
  arch/powerpc/kernel/time.c
  arch/parisc/include/asm/rtc.h
  ...

We can make a common function for this type of conversion, At least we
can get following benefit:

1: Make kernel simple and unify
2: Easy to fix bug in converting code
3: Reduce clone of code in future
   For example, I'm trying to make ftrace display walltime,
   this patch will make me easy.

This code is based on code from glibc-2.6

Subject: doc/filesystems: remove smount program

mount(8) handles shared subtrees just fine, so remove the smount program
from Documentation/filesystems/sharedsubtree.txt.

Fix annoying "Lets" -> "Let's".
Insert space between '#' prompt and "mount" command.

Subject: page-types: add feature for walking process address space

Introduce "-p|--pid <pid>" for walking the process address space.  The
default action is to walk raw memory PFNs.

Both the virtual address and physical address of each present pages will
be listed:

	# ./tools/vm/page-types -lp $$ | head -3
	voffset offset  len     flags
	400     11bebe  1       __RU_lA____M______________________
	402     11bebc  1       __RU_lA____M______________________

Note that voffset/offset/len are now showed as hex numbers.

Subject: cgroups: support named cgroups hierarchies

To simplify referring to cgroup hierarchies in mount statements, and to
allow disambiguation in the presence of empty hierarchies and
multiply-bindable subsystems this patch adds support for naming a new
cgroup hierarchy via the "name=" mount option

A pre-existing hierarchy may be specified by either name or by subsystems;
a hierarchy's name cannot be changed by a remount operation.

Example usage:

# To create a hierarchy called "foo" containing the "cpu" subsystem
mount -t cgroup -oname=foo,cpu cgroup /mnt/cgroup1

# To mount the "foo" hierarchy on a second location
mount -t cgroup -oname=foo cgroup /mnt/cgroup2

+2.3 Mounting hierarchies by name
+--------------------------------
+
+Passing the name=<x> option when mounting a cgroups hierarchy
+associates the given name with the hierarchy.  This can be used when
+mounting a pre-existing hierarchy, in order to refer to it by name
+rather than by its set of active subsystems.  Each hierarchy is either
+nameless, or has a unique name.
+
+The name should match [\w.-]+
+
+When passing a name=<x> option for a new hierarchy, you need to
+specify subsystems manually; the legacy behaviour of mounting all
+subsystems when none are explicitly specified is not supported when
+you give a subsystem a name.
+
+The name of the subsystem appears as part of the hierarchy description
+in /proc/mounts and /proc/<pid>/cgroups.

Subject: cgroups: move the cgroup debug subsys into cgroup.c to access
 internal state

While it's architecturally clean to have the cgroup debug subsystem be
completely independent of the cgroups framework, it limits its usefulness
for debugging the contents of internal data structures.  Move the debug
subsystem code into the scope of all the cgroups data structures to make
more detailed debugging possible.

From 7717f7ba92de485bce8293419a20ffef130f4286 Mon Sep 17 00:00:00 2001

Subject: cgroups: add a back-pointer from struct cg_cgroup_link to struct
 cgroup

Currently the cgroups code makes the assumption that the subsystem
pointers in a struct css_set uniquely identify the hierarchy->cgroup
mappings associated with the css_set; and there's no way to directly
identify the associated set of cgroups other than by indirecting through
the appropriate subsystem state pointers.

This patch removes the need for that assumption by adding a back-pointer
from struct cg_cgroup_link object to its associated cgroup; this allows
the set of cgroups to be determined by traversing the cg_links list in
the struct css_set.

From 2c6ab6d200827e1c41dc71fff3a2ac7473f51777 Mon Sep 17 00:00:00 2001
From: Paul Menage <menage@google.com>
Date: Wed, 23 Sep 2009 15:56:23 -0700
Subject: cgroups: allow cgroup hierarchies to be created with no bound
 subsystems

This patch removes the restriction that a cgroup hierarchy must have at
least one bound subsystem.  The mount option "none" is treated as an
explicit request for no bound subsystems.

A hierarchy with no subsystems can be useful for plain task tracking, and
is also a step towards the support for multiply-bindable subsystems.

As part of this change, the hierarchy id is no longer calculated from the
bitmask of subsystems in the hierarchy (since this is not guaranteed to be
unique) but is allocated via an ida.  Reference counts on cgroups from
css_set objects are now taken explicitly one per hierarchy, rather than
one per subsystem.

Example usage:

mount -t cgroup -o none,name=foo cgroup /mnt/cgroup

Based on the "no-op"/"none" subsystem concept proposed by
kamezawa.hiroyu@jp.fujitsu.com

Subject: cgroups: revert "cgroups: fix pid namespace bug"

The following series adds a "cgroup.procs" file to each cgroup that
reports unique tgids rather than pids, and allows all threads in a
threadgroup to be atomically moved to a new cgroup.

The subsystem "attach" interface is modified to support attaching whole
threadgroups at a time, which could introduce potential problems if any
subsystem were to need to access the old cgroup of every thread being
moved.  The attach interface may need to be revised if this becomes the
case.

Also added is functionality for read/write locking all CLONE_THREAD
fork()ing within a threadgroup, by means of an rwsem that lives in the
sighand_struct, for per-threadgroup-ness and also for sharing a cacheline
with the sighand's atomic count.  This scheme should introduce no extra
overhead in the fork path when there's no contention.

The final patch reveals potential for a race when forking before a
subsystem's attach function is called - one potential solution in case any
subsystem has this problem is to hang on to the group's fork mutex through
the attach() calls, though no subsystem yet demonstrates need for an
extended critical section.

This patch:

    cgroups: fix pid namespace bug

This is in preparation for some clashing cgroups changes that subsume the
original commit's functionaliy.

The original commit fixed a pid namespace bug which Ben Blum fixed
independently (in the same way, but with different code) as part of a
series of patches.  I played around with trying to reconcile Ben's patch
series with Li's patch, but concluded that it was simpler to just revert
Li's, given that Ben's patch series contained essentially the same fix.

Subject: cgroups: add a read-only "procs" file similar to "tasks" that shows
 only unique tgids

struct cgroup used to have a bunch of fields for keeping track of the
pidlist for the tasks file.  Those are now separated into a new struct
cgroup_pidlist, of which two are had, one for procs and one for tasks.
The way the seq_file operations are set up is changed so that just the
pidlist struct gets passed around as the private data.

Interface example: Suppose a multithreaded process has pid 1000 and other
threads with ids 1001, 1002, 1003:
$ cat tasks
1000
1001
1002
1003
$ cat cgroup.procs
1000
$

Subject: cgroups: ensure correct concurrent opening/reading of pidlists across
 pid namespaces

Previously there was the problem in which two processes from different pid
namespaces reading the tasks or procs file could result in one process
seeing results from the other's namespace.  Rather than one pidlist for
each file in a cgroup, we now keep a list of pidlists keyed by namespace
and file type (tasks versus procs) in which entries are placed on demand.
Each pidlist has its own lock, and that the pidlists themselves are passed
around in the seq_file's private pointer means we don't have to touch the
cgroup or its master list except when creating and destroying entries.

Subject: cgroups: use vmalloc for large cgroups pidlist allocations

Separates all pidlist allocation requests to a separate function that
judges based on the requested size whether or not the array needs to be
vmalloced or can be gotten via kmalloc, and similar for kfree/vfree.

Subject: cgroups: change css_set freeing mechanism to be under RCU

Changes css_set freeing mechanism to be under RCU

This is a prepatch for making the procs file writable. In order to free the
old css_sets for each task to be moved as they're being moved, the freeing
mechanism must be RCU-protected, or else we would have to have a call to
synchronize_rcu() for each task before freeing its old css_set.

From be367d09927023d081f9199665c8500f69f14d22 Mon Sep 17 00:00:00 2001

Subject: cgroups: let ss->can_attach and ss->attach do whole threadgroups at a
 time

Alter the ss->can_attach and ss->attach functions to be able to deal with
a whole threadgroup at a time, for use in cgroup_attach_proc.  (This is a
pre-patch to cgroup-procs-writable.patch.)

Currently, new mode of the attach function can only tell the subsystem
about the old cgroup of the threadgroup leader.  No subsystem currently
needs that information for each thread that's being moved, but if one were
to be added (for example, one that counts tasks within a group) this bit
would need to be reworked a bit to tell the subsystem the right
information.

Subject: memcg: remove the overhead associated with the root cgroup

Change the memory cgroup to remove the overhead associated with accounting
all pages in the root cgroup.  As a side-effect, we can no longer set a
memory hard limit in the root cgroup.

A new flag to track whether the page has been accounted or not has been
added as well.  Flags are now set atomically for page_cgroup,
pcg_default_flags is now obsolete and removed.

Subject: memory controller: soft limit documentation

Soft limits is a new feature for the memory resource controller, something
similar has existed in the group scheduler in the form of shares.  The CPU
controllers interpretation of shares is very different though.

Soft limits are the most useful feature to have for environments where the
administrator wants to overcommit the system, such that only on memory
contention do the limits become active.  The current soft limits
implementation provides a soft_limit_in_bytes interface for the memory
controller and not for memory+swap controller.  The implementation
maintains an RB-Tree of groups that exceed their soft limit and starts
reclaiming from the group that exceeds this limit by the maximum amount.

This patch:

Add documentation for soft limits

-7. TODO
+7. Soft limits
+
+Soft limits allow for greater sharing of memory. The idea behind soft limits
+is to allow control groups to use as much of the memory as needed, provided
+
+a. There is no memory contention
+b. They do not exceed their hard limit
+
+When the system detects memory contention or low memory control groups
+are pushed back to their soft limits. If the soft limit of each control
+group is very high, they are pushed back as much as possible to make
+sure that one control group does not starve the others of memory.
+
+Please note that soft limits is a best effort feature, it comes with
+no guarantees, but it does its best to make sure that when memory is
+heavily contended for, memory is allocated based on the soft limit
+hints/setup. Currently soft limit based reclaim is setup such that
+it gets invoked from balance_pgdat (kswapd).
+
+7.1 Interface
+
+Soft limits can be setup by using the following commands (in this example we
+assume a soft limit of 256 megabytes)
+
+# echo 256M > memory.soft_limit_in_bytes
+
+If we want to change this to 1G, we can at any time use
+
+# echo 1G > memory.soft_limit_in_bytes
+
+NOTE1: Soft limits take effect over a long period of time, since they involve
+       reclaiming memory for balancing between memory cgroups
+NOTE2: It is recommended to set the soft limit always below the hard limit,
+       otherwise the hard limit will take precedence.
+
+8. TODO
 
 1. Add support for accounting huge pages (as a separate controller)
 2. Make per-cgroup scanner reclaim not-shared pages first

Subject: memory controller: soft limit interface

Add an interface to allow get/set of soft limits.  Soft limits for memory
plus swap controller (memsw) is currently not supported.  Resource
counters have been enhanced to support soft limits and new type
RES_SOFT_LIMIT has been added.  Unlike hard limits, soft limits can be
directly set and do not need any reclaim or checks before setting them to
a newer value.

Kamezawa-San raised a question as to whether soft limit should belong to
res_counter.  Since all resources understand the basic concepts of hard
and soft limits, it is justified to add soft limits here.  Soft limits are
a generic resource usage feature, even file system quotas support soft
limits.

Subject: memory controller: soft limit organize cgroups

Organize cgroups over soft limit in a RB-Tree

Introduce an RB-Tree for storing memory cgroups that are over their soft
limit.  The overall goal is to

1. Add a memory cgroup to the RB-Tree when the soft limit is exceeded.
   We are careful about updates, updates take place only after a particular
   time interval has passed
2. We remove the node from the RB-Tree when the usage goes below the soft
   limit

The next set of patches will exploit the RB-Tree to get the group that is
over its soft limit by the largest amount and reclaim from it, when we
face memory contention.

From: Balbir Singh <balbir@linux.vnet.ibm.com>

Subject: memory controller: soft limit refactor reclaim flags

Refactor mem_cgroup_hierarchical_reclaim()

Refactor the arguments passed to mem_cgroup_hierarchical_reclaim() into
flags, so that new parameters don't have to be passed as we make the
reclaim routine more flexible

Subject: memory controller: soft limit reclaim on contention

Implement reclaim from groups over their soft limit

Permit reclaim from memory cgroups on contention (via the direct reclaim
path).

memory cgroup soft limit reclaim finds the group that exceeds its soft
limit by the largest number of pages and reclaims pages from it and then
reinserts the cgroup into its correct place in the rbtree.

Add additional checks to mem_cgroup_hierarchical_reclaim() to detect long
loops in case all swap is turned off.  The code has been refactored and
the loop check (loop < 2) has been enhanced for soft limits.  For soft
limits, we try to do more targetted reclaim.  Instead of bailing out after
two loops, the routine now reclaims memory proportional to the size by
which the soft limit is exceeded.  The proportion has been empirically
determined.

[akpm@linux-foundation.org: build fix]

Subject: memcg: improve resource counter scalability

Reduce the resource counter overhead (mostly spinlock) associated with the
root cgroup.  This is a part of the several patches to reduce mem cgroup
overhead.  I had posted other approaches earlier (including using percpu
counters).  Those patches will be a natural addition and will be added
iteratively on top of these.

The patch stops resource counter accounting for the root cgroup.  The data
for display is derived from the statisitcs we maintain via
mem_cgroup_charge_statistics (which is more scalable).  What happens today
is that, we do double accounting, once using res_counter_charge() and once
using memory_cgroup_charge_statistics().  For the root, since we don't
implement limits any more, we don't need to track every charge via
res_counter_charge() and check for limit being exceeded and reclaim.

The main mem->res usage_in_bytes can be derived by summing the cache and
rss usage data from memory statistics (MEM_CGROUP_STAT_RSS and
MEM_CGROUP_STAT_CACHE).  However, for memsw->res usage_in_bytes, we need
additional data about swapped out memory.  This patch adds a
MEM_CGROUP_STAT_SWAPOUT and uses that along with MEM_CGROUP_STAT_RSS and
MEM_CGROUP_STAT_CACHE to derive the memsw data.  This data is computed
recursively when hierarchy is enabled.

The tests results I see on a 24 way show that

1. The lock contention disappears from /proc/lock_stats
2. The results of the test are comparable to running with
   cgroup_disable=memory.

Here is a sample of my program runs

NOTE: The data looks counterintuitive due to the increased performance
with the patch, even over the config being turned off. We probably need
more runs, but so far all testing has shown that the patches definitely
help.

Subject: memcg: show swap usage in stat file

We now count MEM_CGROUP_STAT_SWAPOUT, so we can show swap usage.  It would
be useful for users to show swap usage in memory.stat file, because they
don't need calculate memsw.usage - res.usage to know swap usage.

From: Oleg Nesterov <oleg@redhat.com>
Date: Wed, 23 Sep 2009 15:56:44 -0700
Subject: ptrace: __ptrace_detach: do __wake_up_parent() if we reap the tracee

The bug is old, it wasn't cause by recent changes.

Test case:

	static void *tfunc(void *arg)
	{
		int pid = (long)arg;

		assert(ptrace(PTRACE_ATTACH, pid, NULL, NULL) == 0);
		kill(pid, SIGKILL);

		sleep(1);
		return NULL;
	}

	int main(void)
	{
		pthread_t th;
		long pid = fork();

		if (!pid)
			pause();

		signal(SIGCHLD, SIG_IGN);
		assert(pthread_create(&th, NULL, tfunc, (void*)pid) == 0);

		int r = waitpid(-1, NULL, __WNOTHREAD);
		printf("waitpid: %d %m\n", r);

		return 0;
	}

Before the patch this program hangs, after this patch waitpid() correctly
fails with errno == -ECHILD.

The problem is, __ptrace_detach() reaps the EXIT_ZOMBIE tracee if its
->real_parent is our sub-thread and we ignore SIGCHLD.  But in this case
we should wake up other threads which can sleep in do_wait().

Subject: do_wait() wakeup optimization: shift security_task_wait() from
 eligible_child() to wait_consider_task()

Preparation, no functional changes.

eligible_child() has a single caller, wait_consider_task(). We can move
security_task_wait() out from eligible_child(), this allows us to use it
for filtered wake_up().

Subject: do_wait() wakeup optimization: change __wake_up_parent() to use
 filtered wakeup

Ratan Nalumasu reported that in a process with many threads doing
unnecessary wakeups.  Every waiting thread in the process wakes up to loop
through the children and see that the only ones it cares about are still
not ready.

Now that we have struct wait_opts we can change do_wait/__wake_up_parent
to use filtered wakeups.

We can make child_wait_callback() more clever later, right now it only
checks eligible_child().

Subject: do_wait() wakeup optimization: child_wait_callback: check __WNOTHREAD
 case

Suggested by Roland.

do_wait(__WNOTHREAD) can only succeed if the caller is either ptracer, or
it is ->real_parent and the child is not traced. IOW, caller == p->parent
otherwise we should not wake up.

Change child_wait_callback() to check this. Ratan reports the workload with
CPU load >99% caused by unnecessary wakeups, should be fixed by this patch.

Subject: do_wait-wakeup-optimization: fix
 child_wait_callback()->eligible_child() usage

child_wait_callback()->eligible_child() is not right, we can miss the
wakeup if the task was detached before __wake_up_parent() and the caller
of do_wait() didn't use __WALL.

Move ->wo_pid checks from eligible_child() to the new helper,
eligible_pid(), and change child_wait_callback() to use it instead of
eligible_child().

Note: actually I think it would be better to fix the __WCLONE check in
eligible_child(), it doesn't look exactly right.  But it is not clear what
is the supposed behaviour, and any change is user-visible.

Subject: do_wait-wakeup-optimization: simplify task_pid_type()

task_pid_type() is only used by eligible_pid() which has to check wo_type
!= PIDTYPE_MAX anyway.  Remove this check from task_pid_type() and factor
out ->pids[type] access, this shrinks .text a bit and simplifies the code.

The matches the behaviour of other similar helpers, say get_task_pid().
The caller must ensure that pid_type is valid, not the callee.

Subject: do_wait: fix sys_waitid()-specific behaviour

do_wait() checks ->wo_info to figure out who is the caller.  If it's not
NULL the caller should be sys_waitid(), in that case do_wait() fixes up
the retval or zeros ->wo_info, depending on retval from underlying
function.

This is bug: user can pass ->wo_info == NULL and sys_waitid() will return
incorrect value.

man 2 waitid says:

	waitid(): returns 0 on success

Test-case:

	int main(void)
	{
		if (fork())
			assert(waitid(P_ALL, 0, NULL, WEXITED) == 0);

		return 0;
	}

Result:

	Assertion `waitid(P_ALL, 0, ((void *)0), 4) == 0' failed.

Move that code to sys_waitid().

User-visible change: sys_waitid() will return 0 on success, either
infop is set or not.

Note, there's another bug in wait_noreap_copyout() which affects
return value of sys_waitid(). It will be fixed in next patch.

Subject: wait_noreap_copyout(): check for ->wo_info != NULL

Current behaviour of sys_waitid() looks odd.  If user passes infop ==
NULL, sys_waitid() returns success.  When user additionally specifies flag
WNOWAIT, sys_waitid() returns -EFAULT on the same conditions.  When user
combines WNOWAIT with WCONTINUED, sys_waitid() again returns success.

This patch adds check for ->wo_info in wait_noreap_copyout().

User-visible change: starting from this commit, sys_waitid() always checks
infop != NULL and does not fail if it is NULL.

and changes its argument and return value definition.  These clean-ups
make it a better fit for what new tracing hooks need to check.

Tracing needs the siglock here, held from the time TASK_STOPPED was set,
to avoid potential SIGCONT races if it wants to allow any blocking in its
tracing hooks.

This also folds the finish_stop() function into its caller
do_signal_stop().  The function is short, called only once and only
unconditionally.  It aids readability to fold it in.

Subject: exec: make do_coredump() more resilient to recursive crashes

Change how we detect recursive dumps.

Currently we have a mechanism by which we try to compare pathnames of the
crashing process to the core_pattern path.  This is broken for a dozen
reasons, and just doesn't work in any sort of robust way.

I'm replacing it with the use of a 0 RLIMIT_CORE value.  Since helper apps
set RLIMIT_CORE to zero, we don't write out core files for any process
with that particular limit set.  It the core_pattern is a pipe, any
non-zero limit is translated to RLIM_INFINITY.

This allows complete dumps to be captured, but prevents infinite recursion
in the event that the core_pattern process itself crashes.

Subject: exec: let do_coredump() limit the number of concurrent dumps to pipes

Introduce core pipe limiting sysctl.

Since we can dump cores to pipe, rather than directly to the filesystem,
we create a condition in which a user can create a very high load on the
system simply by running bad applications.

If the pipe reader specified in core_pattern is poorly written, we can
have lots of ourstandig resources and processes in the system.

This sysctl introduces an ability to limit that resource consumption.
core_pipe_limit defines how many in-flight dumps may be run in parallel,
dumps beyond this value are skipped and a note is made in the kernel log.
A special value of 0 in core_pipe_limit denotes unlimited core dumps may
be handled (this is the default value).

Subject: exec: allow do_coredump() to wait for user space pipe readers to
 complete

Allow core_pattern pipes to wait for user space to complete

One of the things that user space processes like to do is look at metadata
for a crashing process in their /proc/<pid> directory.  this is racy
however, since do_coredump in the kernel doesn't wait for the user space
process to complete before it reaps the crashing process.  This patch
corrects that.  Allowing the kernel to wait for the user space process to
complete before cleaning up the crashing process.  This is a bit tricky to
do for a few reasons:

1) The user space process isn't our child, so we can't sys_wait4 on it
2) We need to close the pipe before waiting for the user process to complete,
since the user process may rely on an EOF condition

I've discussed several solutions with Oleg Nesterov off-list about this,
and this is the one we've come up with.  We add ourselves as a pipe reader
(to prevent premature cleanup of the pipe_inode_info), and remove
ourselves as a writer (to provide an EOF condition to the writer in user
space), then we iterate until the user space process exits (which we
detect by pipe->readers == 1, hence the > 1 check in the loop).  When we
exit the loop, we restore the proper reader/writer values, then we return
and let filp_close in do_coredump clean up the pipe data properly.

Subject: exec: fix set_binfmt() vs sys_delete_module() race

sys_delete_module() can set MODULE_STATE_GOING after
search_binary_handler() does try_module_get().  In this case
set_binfmt()->try_module_get() fails but since none of the callers
check the returned error, the task will run with the wrong old
->binfmt.

The proper fix should change all ->load_binary() methods, but we can
rely on fact that the caller must hold a reference to binfmt->module
and use __module_get() which never fails.

Subject: signals: introduce do_send_sig_info() helper

Introduce do_send_sig_info() and convert group_send_sig_info(),
send_sig_info(), do_send_specific() to use this helper.

Hopefully it will have more users soon, it allows to specify
specific/group behaviour via "bool group" argument.

Shaves 80 bytes from .text.

Subject: signals: send_sigio: use do_send_sig_info() to avoid
 check_kill_permission()

group_send_sig_info()->check_kill_permission() assumes that current is the
sender and uses current_cred().

This is not true in send_sigio_to_task() case.  From the security pov the
sender is not current, but the task which did fcntl(F_SETOWN), that is why
we have sigio_perm() which uses the right creds to check.

Fortunately, send_sigio() always sends either SEND_SIG_PRIV or
SI_FROMKERNEL() signal, so check_kill_permission() does nothing.  But
still it would be tidier to avoid this bogus security check and save a
couple of cycles.

Subject: fcntl: add F_[SG]ETOWN_EX

In order to direct the SIGIO signal to a particular thread of a
multi-threaded application we cannot, like suggested by the manpage, put a
TID into the regular fcntl(F_SETOWN) call.  It will still be send to the
whole process of which that thread is part.

Since people do want to properly direct SIGIO we introduce F_SETOWN_EX.

The need to direct SIGIO comes from self-monitoring profiling such as with
perf-counters.  Perf-counters uses SIGIO to notify that new sample data is
available.  If the signal is delivered to the same task that generated the
new sample it can augment that data by inspecting the task's user-space
state right after it returns from the kernel.  This is esp.  convenient
for interpreted or virtual machine driven environments.

Both F_SETOWN_EX and F_GETOWN_EX take a pointer to a struct f_owner_ex
as argument:

struct f_owner_ex {
	int   type;
	pid_t pid;
};

Where type is one of F_OWNER_TID, F_OWNER_PID or F_OWNER_GID.

Subject: signals: inline __fatal_signal_pending

__fatal_signal_pending inlines to one instruction on x86, probably two
instructions on other machines.  It takes two longer x86 instructions just
to call it and test its return value, not to mention the function itself.

On my random x86_64 config, this saved 70 bytes of text (59 of those being
__fatal_signal_pending itself).

Subject: fdpic: ignore the loader's PT_GNU_STACK when calculating the stack
 size

Ignore the loader's PT_GNU_STACK when calculating the stack size, and only
consider the executable's PT_GNU_STACK, assuming the executable has one.

Currently the behaviour is to take the largest stack size and use that,
but that means you can't reduce the stack size in the executable.  The
loader's stack size should probably only be used when executing the loader
directly.

WARNING: This patch is slightly dangerous - it may render a system
inoperable if the loader's stack size is larger than that of important
executables, and the system relies unknowingly on this increasing the size
of the stack.

Subject: fs/char_dev.c: remove useless loop

There are two useless lines in fs/char_dev.c.

In register_chrdev there is a loop to change all '/' into '!' in the
kernel object name.
This code is useless as the same substitution is in kobject_set_name_vargs in
lib/kobject.c:
228         /* ewww... some of these buggers have '/' in the name ... */
229         while ((s = strchr(kobj->name, '/')))
230                 s[0] = '!';

kobject_set_name_vargs is called by kobject_set_name.
kobject_set_name is called just above the useless loop.

Subject: hpet: hpet driver periodic timer setup bug fixes

The periodic interrupt from drivers/char/hpet.c does not work correctly,
both when using the periodic capability of the hardware and while
emulating the periodic interrupt (when hardware does not support periodic
mode).

With timers capable of periodic interrupts, the comparator field is first
set with the period value followed by set of hidden accumulator, which has
the side effect of overwriting the comparator value.  This results in
wrong periodicity for the interrupts.  For, periodic interrupts to work,
following steps are necessary, in that order.

* Set config with Tn_VAL_SET_CNF bit

* Write to hidden accumulator, the value written is the time when the
  first interrupt should be generated

* Write compartor with period interval for subsequent interrupts
  (http://www.intel.com/hardwaredesign/hpetspec_1.pdf )

When emulating periodic timer with timers not capable of periodic
interrupt, driver is adding the period to counter value instead of
comparator value, which causes slow drift when using this emulation.

Also, driver seems to add hpetp->hp_delta both while setting up periodic
interrupt and while emulating periodic interrupts with timers not capable
of doing periodic interrupts.  This hp_delta will result in slower than
expected interrupt rate and should not be used while setting the interval.

Subject: bfin-otp: add writing support

The on-chip OTP may be written at runtime, so enable support for it in the
driver.  However, since writing should really be done only on development
systems, don't bend over backwards to make sure the simple software lock
is per-fd -- per-device is OK.

Subject: sysctl: remove "struct file *" argument of ->proc_handler

It isn't needed -- read or write flag is already passed and sysctl
shouldn't care about the rest.

It _was_ used in two places at arch/frv for some reason.

Subject: fork(): disable CLONE_PARENT for init

When global or container-init processes use CLONE_PARENT, they create a
multi-rooted process tree.  Besides siblings of global init remain as
zombies on exit since they are not reaped by their parent (swapper).  So
prevent global and container-inits from creating siblings.

Subject: pidns: deny CLONE_PARENT|CLONE_NEWPID combination

CLONE_PARENT was used to implement an older threading model.  For
consistency with the CLONE_THREAD check in copy_pid_ns(), disable
CLONE_PARENT with CLONE_NEWPID, at least until the required semantics of
pid namespaces are clear.

Subject: edac: mpc85xx add P2020DS support

Based on Kumar's new compatible types patch, add P2020 into MPC85xx EDAC
compatible lists so that EDAC can recognize P2020 meomry controller and L2
cache controller and export the relevant fields to sysfs.

EDAC MPC85xx DDR3 support is needed if DDR3 memory stick is installed on a
P2020DS board so that EDAC core can recognize DDR3 memory type.

Subject: edac: mpc85xx add mpc83xx support

Add support for the Freescale MPC83xx memory controller to the existing
driver for the Freescale MPC85xx memory controller.  The only difference
between the two processors are in the CS_BNDS register parsing code, which
has been changed so it will work on both processors.

The L2 cache controller does not exist on the MPC83xx, but the OF
subsystem will not use the driver if the device is not present in the OF
device tree.

I had to change the nr_pages calculation to make the math work out.  I
checked it on my board and did the math by hand for a 64GB 85xx using 64K
pages.  In both cases, nr_pages * PAGE_SIZE comes out to the correct
value.

A driver for the Intel 3200 and 3210 memory controllers.  It has only had
light testing so far, and currently makes no attempt to decode error
addresses at anything finer than csrow granularity.

From 458e5ff13e1bed050990d97e9aa55bcdafc951a7 Mon Sep 17 00:00:00 2001
From: Jesper Dangaard Brouer <hawk@comx.dk>

Subject: edac: core: remove completion-wait for complete with rcu_barrier

Module edac_core.ko uses call_rcu() callbacks in edac_device.c, edac_mc.c
and edac_pci.c.

They all use a wait_for_completion() scheme, but this scheme it not 100%
safe on multiple CPUs.  See the _rcu_barrier() implementation which
explains why extra precausion is needed.

The patch adds a comment about rcu_barrier() and as a precausion calls
rcu_barrier().  A maintainer needs to look at removing the
wait_for_completion code.

Subject: memstick: move dev_dbg

id_reg.if_mode might be unitialized when (*mrq)->error is nonzero.  move
dev_dbg() inside the if so that we are sure we can use id_reg values.

In this case, the calls to request_mem_region, ioremap, and
release_mem_region all have a consistent length argument, len, but since

resource_size(res), is used for a resource-typed structure res, one could
consider whether the same should be done here.

obtain more data, leading to a kernel oops.

Subject: include/linux/unaligned/{l,b}e_byteshift.h: fix usage for compressed
 kernels

When unaligned accesses are required for uncompressing a kernel (such as
for LZO decompression on ARM in a patch that follows), including
<linux/kernel.h> causes issues as it brings in a lot of things that are
not available in the decompression environment.

linux/kernel.h brings at least:
extern int console_printk[];
extern const char hex_asc[];
which causes errors at link-time as they are not available when
compiling the pre-boot environement. There are also a few others:

  arch/arm/boot/compressed/misc.o: In function `valid_user_regs':
   arch/arm/include/asm/ptrace.h:158: undefined reference to `elf_hwcap'
  arch/arm/boot/compressed/misc.o: In function `console_silent':
   include/linux/kernel.h:292: undefined reference to `console_printk'
  arch/arm/boot/compressed/misc.o: In function `console_verbose':
   include/linux/kernel.h:297: undefined reference to `console_printk'
  arch/arm/boot/compressed/misc.o: In function `pack_hex_byte':
   include/linux/kernel.h:360: undefined reference to `hex_asc'
  arch/arm/boot/compressed/misc.o: In function `hweight_long':
   include/linux/bitops.h:45: undefined reference to `hweight32'
  arch/arm/boot/compressed/misc.o: In function `__cmpxchg_local_generic':
   include/asm-generic/cmpxchg-local.h:21: undefined reference to `wrong_size_cmpxchg'
   include/asm-generic/cmpxchg-local.h:42: undefined reference to `wrong_size_cmpxchg'
  arch/arm/boot/compressed/misc.o: In function `__xchg':
   arch/arm/include/asm/system.h:309: undefined reference to `__bad_xchg'

However, those files apparently use nothing from <linux/kernel.h>, all
they need is the declaration of types such as u32 or u64, so
<linux/types.h> should be enough

Subject: alpha: AGP update (fixes compile failure)

This brings Alpha AGP platforms in sync with the change to struct
agp_memory (unsigned long *memory => struct page **pages).

Only compile tested (I don't have titan/marvel hardware), but this change
looks pretty straightforward, so hopefully it's ok.

Also remove all parts of the string table (referenced by the symbol
table) that are not needed for kallsyms use (i.e. which were only
referenced by symbols discarded by the previous patch, or not
referenced at all for whatever reason).

Subject: param: allow whitespace as kernel parameter separator

Some boot mechanisms require that kernel parameters are stored in a
separate file which is loaded to memory without further processing
(e.g. the "Load from FTP" method on s390). When such a file contains
newline characters, the kernel parameter preceding the newline might
not be correctly parsed (due to the newline being stuck to the end of
the actual parameter value) which can lead to boot failures.

This patch improves kernel command line usability in such a situation
by allowing generic whitespace characters as separators between kernel
parameters.

Subject: module: fix memory leak when load fails after srcversion/version
 allocated

Normally the twisty paths of sysfs will free the attributes, but not if
we fail before we hook it into sysfs (which is the last thing we do in
load_module).

(This sysfs code is a turd, no doubt there are other issues lurking too).

Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The general one handles NULL, the static obsolescent
(CONFIG_HAVE_LEGACY_PER_CPU_AREA) one in module.c doesn't; Eric's
commit 720eba31 assumed it did, and various frobbings since then kept
that assumption.

All other callers in module.c all protect it with an if; this effectively
does the same as free_init is only goto if we fail percpu_modalloc().

Subject: cifs: convert oplock breaks to use slow_work facility (try #4)

This is the fourth respin of the patch to convert oplock breaks to
use the slow_work facility.

A customer of ours was testing a backport of one of the earlier
patchsets, and hit a "Busy inodes after umount..." problem. An oplock
break job had raced with a umount, and the superblock got torn down and
its memory reused. When the oplock break job tried to dereference the
inode->i_sb, the kernel oopsed.

This patchset has the oplock break job hold an inode and vfsmount
reference until the oplock break completes.  With this, there should be
no need to take a tcon reference (the vfsmount implicitly holds one
already).

Currently, when an oplock break comes in there's a chance that the
oplock break job won't occur if the allocation of the oplock_q_entry
fails. There are also some rather nasty races in the allocation and
handling these structs.

Rather than allocating oplock queue entries when an oplock break comes
in, add a few extra fields to the cifsFileInfo struct. Get rid of the
dedicated cifs_oplock_thread as well and queue the oplock break job to
the slow_work thread pool.

This approach also has the advantage that the oplock break jobs can
potentially run in parallel rather than be serialized like they are
today.

Subject: IB/mthca: Fix access to freed memory in catastrophic event handling

catas_reset() uses a pointer to mthca_dev, but mthca_dev is not valid
after the call to __mthca_restart_one().

Based on a similar patch for mlx4 (634354d7, "mlx4: Fix access to
freed memory") by Vitaliy Gusev <vgusev@openvz.org>

Subject: nfs[23] tcp breakage in mount with binary options

We forget to set nfs_server.protocol in tcp case when old-style binary
options are passed to mount.  The thing remains zero and never validated
afterwards.  As the result, we hit BUG in fs/nfs/client.c:588.

Breakage has been introduced in NFS: Add nfs_alloc_parsed_mount_data
merged yesterday...

Subject: IPoIB: Don't turn on carrier for a non-active port

Multicast joins can succeed even if the IB port is down.  This happens
when the SM runs on the same port with the requesting port.  However,
IPoIB calls netif_carrier_on() when the join of the broadcast group
succeeds, without caring about the state of the IB port.  The result
is an IPoIB interface in RUNNING state but without an active IB port
to support it.

If a bonding interface uses this IPoIB interface as a slave it might
not detect that this slave is almost useless and failover
functionality will be damaged.  The fix checks the state of the IB
port in the carrier_task before calling netif_carrier_on().

Subject: intel-iommu: Decode (and ignore) RHSA entries

I recently got a system where the DMAR table included a couple of RHSA
(remapping hardware static affinity) entries.  Rather than printing a
message about an "Unknown DMAR structure," it would probably be more
useful to dump the RHSA structure (as other DMAR structures are dumped).

openat() is still a young glibc facility, better to not use it in a
non performance critical program (perf list)

Many machines have older glibc (RHEL 4 Update 5 -> glibc-2.3.4-2.36
on my dev machine for example).

Subject: cifs: eliminate cifs_init_private

...it does the same thing as cifs_fill_fileinfo, but doesn't handle the
flist ordering correctly. Also rename cifs_fill_fileinfo to a more
descriptive name and have it take an open flags arg instead of just a
write_only flag. That makes the logic in the callers a little simpler.

Subject: mtd/maps: gpio-addr-flash: depend on GPIO arch support

The driver requires gpio functionality, so make sure we depend on that in
the Kconfig menu.

Subject: clocksource: Resume clocksource without taking the clocksource mutex

git commit 75c5158f70c065b9 converted the clocksource spinlock to a
mutex. This causes the following BUG:

clocksource_resume is called early in the resume process, there is
only one cpu, no processes are running and the interrupts are
disabled. It is therefore possible to resume the clocksources
without taking the clocksource mutex.

Subject: ipv4: check optlen for IP_MULTICAST_IF option

Due to man page of setsockopt, if optlen is not valid, kernel should return
-EINVAL. But a simple testcase as following, errno is 0, which means setsockopt
is successful.
	addr.s_addr = inet_addr("192.1.2.3");
	setsockopt(s, IPPROTO_IP, IP_MULTICAST_IF, &addr, 1);
	printf("errno is %d\n", errno);

Xiaotian Feng(dfeng@redhat.com) caught the bug. We fix it firstly checking
the availability of optlen and then dealing with the logic like other options.

Subject: pktgen: better scheduler friendliness

Previous update did not resched in inner loop causing watchdogs.
Rewrite inner loop to:
  * account for delays better with less clock calls
  * more accurate timing of delay:
    - only delay if packet was successfully sent
    - if delay is 100ns and it takes 10ns to build packet then
      account for that
  * use wait_event_interruptible_timeout rather than open coding it.

Allocating a port number to a socket and hashing that socket shall be
an atomic operation with regards to other port allocation. Otherwise,
we could allocate a port that is already being allocated to another
socket.

Subject: ems_pci: fix size of CAN controllers BAR mapping for CPC-PCI v2

The driver mapped only 128 bytes of the CAN controller address space when a
CPC-PCI v2 was detected (incl. CPC-104P). This patch will fix it by always
mapping the whole address space (4096 bytes on all boards) of the
corresponding PCI BAR.

Subject: tunnel: eliminate recursion field

It seems recursion field from "struct ip_tunnel" is not anymore needed.
recursion prevention is done at the upper level (in dev_queue_xmit()),
since we use HARD_TX_LOCK protection for tunnels.

This avoids a cache line ping pong on "struct ip_tunnel" : This structure
should be now mostly read on xmit and receive paths.

This is because the driver manages interrupts without checking for
netif_running().

Though, there are few other issues with suspend/resume in this driver.
The intention of calling free_irq() in suspend() was to avoid any
possible spurious interrupts (see commit 5b039e681b8c5f30aac9cc04385
"3c59x PM fixes"). But,

- On resume, the driver was requesting IRQ just after pci_set_master(),
  but before vortex_up() (which actually resets 3c59x chips).

- Issuing free_irq() on a shared IRQ doesn't guarantee that a buggy
  HW won't trigger spurious interrupts in another driver that
  requested the same interrupt. So, if we want to protect from
  unexpected interrupts, then on suspend we should issue disable_irq(),
  not free_irq().

Subject: genetlink: fix netns vs. netlink table locking (2)

Similar to commit d136f1bd366fdb7e747ca7e0218171e7a00a98a5,
there's a bug when unregistering a generic netlink family,
which is caught by the might_sleep() added in that commit:

    BUG: sleeping function called from invalid context at net/netlink/af_netlink.c:183

Fix in the same way by grabbing the netlink table lock
before doing rcu_read_lock().

Subject: omap: Fix compile for arch/arm/mach-omap2

Patch 941132606c7611246d2034cb7b01f9270c2d1ede split IO_ADDRESS
into OMAP1_IO_ADDRESS and OMAP2_IO_ADDRESS except for the omap4
code to avoid merge conflicts with the omap4 code that was queued
earlier.

Subject: omap: mailbox: Flush posted write when acking mailbox irq

The only way to flush posted write to L4 bus is to do a read back
of the same register right after the write.

This seems to be mostly needed in interrupt handlers to avoid
causing spurious interrupts.

The earlier fix has been to mark the L4 bus as strongly ordered
memory, which solves the problem, but causes performance penalties.

Similar to the fix, 03803a71041e3bc3c077f4e7b92f6ceaa9426df3

Subject: omap: Fix MMC gpio_wp for BeagleBoard C2 and above

Earlier BeagleBoards were using pad AH8 muxed to GPIO29 for MMC write-protect.
However, this signal has been changed to pad AG9 in board revision C2.

Fix this by adding mux configuration for pad AG9, runtime check for board
revisions and set the gpio number and pad muxing accordingly.

Subject: hugetlb_file_setup(): use C, not cpp

Why macros are always wrong:

  mm/mmap.c: In function 'do_mmap_pgoff':
  mm/mmap.c:953: warning: unused variable 'user'

also, move a couple of struct forward-decls outside `#ifdef
CONFIG_HUGETLB_PAGE' - it's pointless and frequently harmful to make these
conditional (eg, this patch needed `struct user_struct').

Subject: Optimize the ordering of sections in RW_DATA_SECTION.

The old RW_DATA_SECTION had INIT_TASK_DATA (which was
more-than-PAGE_SIZE-aligned), followed by a bunch of small alignment
stuff, followed by more PAGE_SIZE-aligned stuff, so you wasted memory
in the middle of .data re-aligning back up to PAGE_SIZE.

This patch sorts the sections by alignment requirements, which should
pack them essentially optimally.

Subject: parisc: Clean up linker script using new linker script macros.

This patch has the (likely harmless) side effect of moving
.data.init_task inside the _edata.

It also changes the alignment of .data.init_task from 16384 to
THREAD_SIZE, which can in some configurations be larger than 16384.  I
believe that this change fixes a potential bug on those
configurations.

Subject: alpha: use .data.init_task instead of .data.init_thread.

alpha is the only architecture that uses the section name
.data.init_thread instead of .data.init_task.  So convert alpha to use
.data.init_task like everything else.

.data.init_task does not need a separate output section; this change
also moves it into the .data output section.

Subject: alpha: Clean up linker script using new linker script macros.

Note that .data.page_aligned and .data.cacheline_aligned are now after
_data; it was probably a bug that they were before it.

Also, some explicit ALIGN(8)'s between various initcall sections were
removed; this should be harmless as the implicit alignment of
initcall_t was already 8.

From 645d83c5db970a1c57225e155113b4aa2451e920 Mon Sep 17 00:00:00 2001

Subject: NOMMU: Fix MAP_PRIVATE mmap() of objects where the data can be mapped
 directly

Fix MAP_PRIVATE mmap() of files and devices where the data in the backing store
might be mapped directly.  Use the BDI_CAP_MAP_DIRECT capability flag to govern
whether or not we should be trying to map a file directly.  This can be used to
determine whether or not a region has been filled in at the point where we call
do_mmap_shared() or do_mmap_private().

The BDI_CAP_MAP_DIRECT capability flag is cleared by validate_mmap_request() if
there's any reason we can't use it.  It's also cleared in do_mmap_pgoff() if
f_op->get_unmapped_area() fails.

Without this fix, attempting to run a program from a RomFS image on a
non-mappable MTD partition results in a BUG as the kernel attempts XIP, and
this can be caught in gdb:

Program received signal SIGABRT, Aborted.

From 513bcb4655e68706594e45dfa1d4b181500110ba Mon Sep 17 00:00:00 2001
From: Dave Airlie <airlied@redhat.com>
Date: Wed, 23 Sep 2009 16:56:27 +1000
Subject: drm/radeon/kms: don't require up to 64k allocations. (v2)

This avoids needing to do a kmalloc > PAGE_SIZE for the main
indirect buffer chunk, it adds an accessor for all reads from
the chunk and caches a single page at a time for subsequent
reads.

changes since v1:
Use a two page pool which should be the most common case
a single packet spanning > PAGE_SIZE will be hit, but I'm
having trouble seeing anywhere we currently generate anything like that.
hopefully proper short page copying at end
added parser_error flag to set deep errors instead of having to test
every ib value fetch.
fixed bug in patch that went to list.

Having a : should be enough 'fb:' isn't really useful
if the fb wants to a kms output ID.

From d50ba256b5f1478e15accfcfda9b72fd7a661364 Mon Sep 17 00:00:00 2001
From: Dave Airlie <airlied@linux.ie>
Date: Wed, 23 Sep 2009 14:44:08 +1000
Subject: drm/kms: start adding command line interface using fb.

[note this requires an fb patch posted to linux-fbdev-devel already]

This uses the normal video= command line option to control the kms
output setup at boot time. It is used to override the autodetection
done by kms.

video= normally takes a framebuffer as the first parameter, in kms
it will take a connector name, DVI-I-1, or LVDS-1 etc. If no output
connector is specified the mode string will apply to all connectors.

The mode specification used will match down the probed modes, and if
no mode is found it will add a CVT mode that matches.

video=1024x768 - all connectors match a 1024x768 mode or add a CVT on
video=VGA-1:1024x768, VGA-1 connector gets mode only.

The same strings as used in current fb modedb.c are used, except I've
added three more letters, e, D, d, e = enable, D = enable Digital,
d = disable, which allow a connector to be forced into a certain state.

Subject: drm/r600: get values from the passed in IB not the copy.

this avoids reading back the IB on AGP, also it avoids
the race where since we haven't fetched the page from the main IB
and written it to the gpu one, reading back fetches 0.

Subject: [IA64] implement ticket locks for Itanium

Back in January 2008 Nick Piggin implemented "ticket" spinlocks
for X86 (See commit 314cdbefd1fd0a7acf3780e9628465b77ea6a836).

IA64 implementation has a couple of differences because of the
available atomic operations ... e.g. we have no fetchadd2 instruction
that operates on a 16-bit quantity so we make ticket locks use
a 32-bit word for each of the current ticket and now-serving values.

Performance on uncontended locks is about 8% worse than the previous
implementation, but this seems a good trade for determinism in the
contended case. Performance impact on macro-level benchmarks is in
the noise.

Subject: fs: Fix busyloop in wb_writeback()

If all inodes are under writeback (e.g. in case when there's only one inode
with dirty pages), wb_writeback() with WB_SYNC_NONE work basically degrades
to busylooping until I_SYNC flags of the inode is cleared. Fix the problem by
waiting on I_SYNC flags of an inode on b_more_io list in case we failed to
write anything.

Subject: writeback: balance_dirty_pages() shall write more than dirtied pages

Some filesystem may choose to write much more than ratelimit_pages
before calling balance_dirty_pages_ratelimited_nr(). So it is safer to
determine number to write based on real number of dirtied pages.

Otherwise it is possible that
  loop {
    btrfs_file_write():     dirty 1024 pages
    balance_dirty_pages():  write up to 48 pages (= ratelimit_pages * 1.5)
  }
in which the writeback rate cannot keep up with dirty rate, and the
dirty pages go all the way beyond dirty_thresh.

The increased write_chunk may make the dirtier more bumpy.
So filesystems shall be take care not to dirty too much at
a time (eg. > 4MB) without checking the ratelimit.

Subject: writeback: stop background writeback when below background threshold

Treat bdi_start_writeback(0) as a special request to do background write,
and stop such work when we are below the background dirty threshold.

Also simplify the (nr_pages <= 0) checks. Since we already pass in
nr_pages=LONG_MAX for WB_SYNC_ALL and background writes, we don't
need to worry about it being decreased to zero.

Subject: writeback: kupdate writeback shall not stop when more io is possible

Fix the kupdate case, which disregards wbc.more_io and stop writeback
prematurely even when there are more inodes to be synced.

wbc.more_io should always be respected.

Also remove the pages_skipped check. It will set when some page(s) of some
inode(s) cannot be written for now. Such inodes will be delayed for a while.
This variable has nothing to do with whether there are other writeable inodes.

Subject: writeback: move inodes from one super_block together

__mark_inode_dirty adds inode to wb dirty list in random order. If a disk has
several partitions, writeback might keep spindle moving between partitions.
To reduce the move, better write big chunk of one partition and then move to
another. Inodes from one fs usually are in one partion, so idealy move indoes
from one fs together should reduce spindle move. This patch tries to address
this. Before per-bdi writeback is added, the behavior is write indoes
from one fs first and then another, so the patch restores previous behavior.
The loop in the patch is a bit ugly, should we add a dirty list for each
superblock in bdi_writeback?

Test in a two partition disk with attached fio script shows about 3% ~ 6%
improvement.

Subject: writeback: make the super_block pinning more efficient

Currently we pin the inode->i_sb for every single inode. This
increases cache traffic on sb->s_umount sem. Lets instead
cache the inode sb pin state and keep the super_block pinned
for as long as keep writing out inodes from the same
super_block.

Subject: writeback: don't delay inodes redirtied by a fast dirtier

Debug traces show that in per-bdi writeback, the inode under writeback
almost always get redirtied by a busy dirtier.  We used to call
redirty_tail() in this case, which could delay inode for up to 30s.

This is unacceptable because it now happens so frequently for plain cp/dd,
that the accumulated delays could make writeback of big files very slow.

So let's distinguish between data redirty and metadata only redirty.
The first one is caused by a busy dirtier, while the latter one could
happen in XFS, NFS, etc. when they are doing delalloc or updating isize.

The inode being busy dirtied will now be requeued for next io, while
the inode being redirtied by fs will continue to be delayed to avoid
repeated IO.

The patch to remove cifs_init_private introduced a locking imbalance. It
didn't remove the leftover list addition code and the unlocking in that
function. cifs_new_fileinfo does the list addition now, so there should
be no need to do it outside of that function.

pCifsInode will never be NULL, so we don't need to check for that. This
patch also gets rid of the ugly locking and unlocking across function
calls.

Subject: ACPICA: fixup after acpi_get_object_info() change

Commit 15b8dd53f5ffa changed info->hardware_id from a static array to
a pointer.  If hardware_id is non-NULL, it points to a NULL-terminated
string, so we don't need to terminate it explicitly.  However, it may
be NULL; in that case, we *can't* add a NULL terminator.

This causes a NULL pointer dereference oops for devices without _HID.

Subject: ACPI: remove redundant "handle" and "parent" arguments

In several cases, functions take handle and parent device pointers in
addition to acpi_device pointers.  But the acpi_device structure contains
both the handle and the parent pointer, so it's pointless and error-prone
to pass them all.  This patch removes the unnecessary "handle" and "parent"
arguments.

Subject: ACPI: save device_type in acpi_device

Most uses of the ACPI bus device_type (ACPI_BUS_TYPE_DEVICE,
ACPI_BUS_TYPE_POWER, etc) are during device initialization, but
we do need it later for notify handler installation, since that
is different for fixed hardware devices vs. namespace devices.

This patch saves the device_type in the acpi_device structure,
so we can check that rather than comparing against the _HID string.

Subject: ACPI: remove acpi_device_set_context() "type" argument

We only pass the "type" to acpi_device_set_context() so we know whether
the device has a handle to which we can attach the acpi_device pointer.
But it's safer to just check for the handle directly, since it's in the
acpi_device already.

Subject: ACPI: remove unnecessary argument checking

acpi_add_single_object() is static, and all callers supply a valid "child"
argument, so we don't need to check it.  This patch also remove some
unnecessary initializations.

Subject: ACPI: add acpi_bus_get_parent() and remove "parent" arguments

This patch adds acpi_bus_get_parent(), which ascends the namespace until
it finds a parent with an acpi_device.

Then we use acpi_bus_get_parent() in acpi_add_single_object(), so callers
don't have to figure out or keep track of the parent acpi_device.

Subject: ACPI: convert acpi_bus_scan() to operate on an acpi_handle

This patch changes acpi_bus_scan() to take an acpi_handle rather than an
acpi_device pointer.  I plan to use acpi_bus_scan() in the hotplug path,
and I'd rather not assume that notifications only go to nodes that already
have acpi_devices.

This will also help remove the special case for adding the root node.  We
currently add the root by hand before acpi_bus_scan(), but using a handle
here means we can start the acpi_bus_scan() directly with the root even
though it doesn't have an acpi_device yet.

Note that acpi_bus_scan() currently adds and/or starts the *children* of
its device argument.  It doesn't do anything with the device itself.

 devices

This patch changes the order so we enumerate in the "root, namespace,
functional fixed" order instead of the "root, functional fixed, namespace"
order.  When I change acpi_bus_scan() to use acpi_walk_namespace(), it
will use the former order, so this patch isolates the order change for
bisectability.

Subject: ACPI: identify device tree root by null parent pointer, not
 ACPI_BUS_TYPE

We can identify the root of the ACPI device tree by the fact that it
has no parent.  This is simpler than passing around ACPI_BUS_TYPE_SYSTEM
and will help remove special treatment of the device tree root.

Currently, we add the root by hand with ACPI_BUS_TYPE_SYSTEM.  If we
traverse the tree treating the root as just another device and use
acpi_get_type(), the root shows up as ACPI_TYPE_DEVICE.

Subject: ACPI: use acpi_walk_namespace() to enumerate devices

acpi_bus_scan() currently walks the namespace manually.  This patch changes
it to use acpi_walk_namespace() instead.

Besides removing some complicated code, this means we take advantage of the
namespace locking done by acpi_walk_namespace().  The locking isn't so
important at boot-time, but I hope to eventually use this same path to
handle hot-addition of devices, when it will be important.

Note that acpi_walk_namespace() does not actually visit the starting node
first, so we need to do that by hand first.

Subject: ACPI: add acpi_bus_get_status_handle()

Add acpi_bus_get_status_handle() so we can get the status of a namespace
object before building a struct acpi_device.

This removes a use of "device->flags.dynamic_status", a cached indicator of
whether _STA exists.  It seems simpler and more reliable to just evaluate
_STA and catch AE_NOT_FOUND errors.

Subject: ACPI: factor out device type and status checking

This patch adds acpi_bus_type_and_status(), which determines the type
of the object and whether we want to build an acpi_device for it.  If
it is acpi_device-worthy, it returns the type and the device's current
status.

Subject: ACPI: handle re-enumeration, when acpi_devices might already exist

acpi_bus_scan() traverses the namespace to enumerate devices and uses
acpi_add_single_object() to create acpi_devices.  When the platform
notifies us of a hot-plug event, we need to traverse part of the namespace
again to figure out what appeared or disappeared.  (We don't yet call
acpi_bus_scan() during hot-plug, but I plan to do that in the future.)

This patch makes acpi_add_single_object() notice when we already have
an acpi_device, so we don't need to make a new one.

This makes \_SB_ show up as /sys/devices/LNXSYSTM:00/LNXSYBUS:00
rather than "device:00".  This has been broken for a loooong time
(at least since 2.6.13) because device->parent is an acpi_device

Subject: ACPI: make sure every acpi_device has an ID

This makes sure every acpi_device has at least one ID.  If we build an
acpi_device for a namespace node with no _HID or _CID, we sometimes
synthesize an ID like "LNXCPU" or "LNXVIDEO".  If we don't even have
that, give it a default "device" ID.

Note that this means things like:
    /sys/devices/LNXSYSTM:00/LNXSYBUS:00/HWP0001:00/HWP0002:04/device:00
(a PCI slot SxFy device) will have "hid" and "modprobe" entries, where
they didn't before.  These aren't very useful (a HID of "device" doesn't
tell you what *kind* of device it is, so it doesn't help find a driver),
but I don't think they're harmful.

Subject: ACPI: maintain a single list of _HID and _CID IDs

There's no need to treat _HID and _CID differently.  Keeping them in
a single list makes code that uses the IDs a little simpler because it
can just traverse the list rather than checking "do we have a HID?",
"do we have any CIDs?"

Subject: ACPI: remove acpi_device.flags.hardware_id

Every acpi_device has at least one ID (if there's no _HID or _CID, we
give it a synthetic or default ID).  So there's no longer a need to
check whether an ID exists; we can just use it.

+ *
+ * Theory of Operation:
+ *
+ * 12 of the 16 mailboxes on the chip are reserved for RX. we split
+ * them into 2 groups. The lower group holds 8 and upper 4 mailboxes.
+ *
+ * Like it or not, but the chip always saves a received CAN message
+ * into the first free mailbox it finds (starting with the
+ * lowest). This makes it very difficult to read the messages in the
+ * right order from the chip. This is how we work around that problem:
+ *
+ * The first message goes into mb nr. 0 and issues an interrupt. All
+ * rx ints are disabled in the interrupt handler and a napi poll is
+ * scheduled. We read the mailbox, but do _not_ reenable the mb (to
+ * receive another message).
+ *
+ *    lower mbxs      upper
+ *   ______^______    __^__
+ *  /             \  /     \
+ * +-+-+-+-+-+-+-+-++-+-+-+-+
+ * |x|x|x|x|x|x|x|x|| | | | |

+ *  0 1 2 3 4 5  6 7 8 9 0 1  / box
+ *
+ * The variable priv->rx_next points to the next mailbox to read a
+ * message from. As long we're in the lower mailboxes we just read the
+ * mailbox but not reenable it.
+ *
+ * With completion of the last of the lower mailboxes, we reenable the
+ * whole first group, but continue to look for filled mailboxes in the
+ * upper mailboxes. Imagine the second group like overflow mailboxes,
+ * which takes CAN messages if the lower goup is full. While in the
+ * upper group we reenable the mailbox right after reading it. Giving
+ * the chip more room to store messages.
+ *
+ * After finishing we look again in the lower group if we've still

Subject: writeback: pass in super_block to bdi_start_writeback()

Sometimes we only want to write pages from a specific super_block,
so allow that to be passed in.

This fixes a problem with commit 56a131dcf7ed36c3c6e36bea448b674ea85ed5bb
causing writeback on all super_blocks on a bdi, where we only really
want to sync a specific sb from writeback_inodes_sb().

Subject: drm/radeon/r600: fix offset handling in CS parser

Need add reloc offset to the offset in the actual
packet.  Fixes use of the DRAW_INDEX packet by the 3D
driver.

[airlied: modified first one where idx_value == ib[idx+0]

We recently removed the acpi_device_uid() interface because nobody
used it.  I don't think it's essential here either.

Subject: backlight: extend event support to also support poll()

Extend the backlight event support to also allow the use of
poll()/select() on actual_brightness.

We already have the entire event hookup anyway, adding a single
function call in one line to get functionality like that is a really
good deal.

Subject: make Linux bootable on ARM again
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Commit 200b812d00 "Clear the exclusive monitor when returning from an
exception" broke the vast majority of ARM systems in the wild which are
still pre ARMv6.  The kernel is crashing on the first occurrence of an
exception due to the removal of the actual return instruction for them.
Let's add it back.

This allows the user to see what filesystem was involved with a
particular ext4_da_writepage() error.  Also, use KERN_CRIT which is
more appropriate than KERN_EMERG.

Subject: e1000: drop dead pcie code from e1000

this patch is the first in a series of clean up patches for e1000 to drop
unused code, and update the driver to kernel spec, and then, to update the
driver to have all available bug fixes.

Call it the e1000 weight loss plan.

of some of the newer hardware designs using SERDES connections, tests
for link must completely cover all cases.

Currently, the nlmsg->len field is not set correctly in  netlink_ack()
for ack messages that include the nlmsg of the error frame.  This
corrects the length field passed to __nlmsg_put to use the correct
payload size.

Subject: net: fix double skb free in dcbnl

netlink_unicast() calls kfree_skb even in the error case.

dcbnl calls netlink_unicast() which when it fails free's the
skb and returns an error value.  dcbnl is free'ing the skb
again when this error occurs.  This patch removes the double
free.

Subject: Revert "sit: stateless autoconf for isatap"

This reverts commit 645069299a1c7358cf7330afe293f07552f11a5d.

While the code does not actually break anything, it does not completely follow
RFC5214 yet. After talking back with Fred L. Templin, I agree that completing the
ISATAP specific RS/RA code, would pollute the kernel a lot with code that is better
implemented in userspace.

The kernel should not send RS packages for ISATAP at all.

Subject: ACPI: Clarify resource conflict message

The message "ACPI: Device needs an ACPI driver" is misleading. The
device _may_ need an ACPI driver, if the BIOS implemented a custom
API for the device in question (which, AFAIK, can't be checked.) If
not, then either a generic ACPI driver may be used (for example
"thermal"), or nothing can be done (other than a white list).

I propose to reword the message to:

ACPI: If an ACPI driver is available for this device, you should use
it instead of the native driver

which I think is more correct. Comments and suggestions welcome.

I also added a message warning about possible problems and system
instability when users pass acpi_enforce_resources=lax, as suggested
by Len.

Subject: ACPI: fix Compaq Evo N800c (Pentium 4m) boot hang regression

Don't disable ARB_DISABLE when the familary ID is 0x0F.

http://bugzilla.kernel.org/show_bug.cgi?id=14211

This was a 2.6.31 regression, and so this patch
needs to be applied to 2.6.31.stable

Subject: x86: Fix hwpoison code related build failure on 32-bit NUMAQ

This build failure triggers:

 In file included from include/linux/suspend.h:8,
                 from arch/x86/kernel/asm-offsets_32.c:11,
                 from arch/x86/kernel/asm-offsets.c:2:
 include/linux/mm.h:503:2: error: #error SECTIONS_WIDTH+NODES_WIDTH+ZONES_WIDTH > BITS_PER_LONG - NR_PAGEFLAGS

Because due to the hwpoison page flag we ran out of page
flags on 32-bit.

Dont turn on hwpoison on 32-bit NUMA (it's rare in any
case).

Also clean up the Kconfig dependencies in the generic MM
code by introducing ARCH_SUPPORTS_MEMORY_FAILURE.

Subject: ACPI: Kill overly verbose "power state" log messages

I was recently lucky enough to get a 64-CPU system, so my kernel log
ends up with 64 lines like:

    ACPI: CPU0 (power states: C1[C1] C2[C3])

This is pretty useless clutter because this info is already available
after boot from both /sys/devices/system/cpu/cpu*/cpuidle/state?/ as
well as /proc/acpi/processor/CPU*/power.

So just delete the code that prints the C-states in processor_idle.c.

Subject: ACPI: IA64=y ACPI=n build fix

ia64's sim_defconfig uses CONFIG_ACPI=n
which now #define's acpi_disabled in <linux/acpi.h>

So we shouldn't re-define it here in <asm/acpi.h>

Commit 3d5b6fb47a8e68fa311ca2c3447e7f8a7c3a9cf3 ("ACPI: Kill overly
verbose "power state" log messages") removed the actual use of this
variable, but didn't remove the variable itself, resulting in build
warnings like

  drivers/acpi/processor_idle.c: In function ‘acpi_processor_power_init’:
  drivers/acpi/processor_idle.c:1169: warning: unused variable ‘i’

Just get rid of the now unused variable.

Subject: tty: Fix regressions caused by commit b50989dc

The following commit made console open fails while booting:

	commit b50989dc444599c8b21edc23536fc305f4e9b7d5
	Author: Alan Cox <alan@linux.intel.com>
	Date:   Sat Sep 19 13:13:22 2009 -0700

	tty: make the kref destructor occur asynchronously

Due to tty release routines run in a workqueue now, error like the
following will be reported while booting:

INIT open /dev/console Input/output error

It also causes hibernation regression to appear as reported at
http://bugzilla.kernel.org/show_bug.cgi?id=14229

The reason is that now there's latency issue with closing, but when
we open a "closing not finished" tty, -EIO will be returned.

Fix it as per the following Alan's suggestion:

  Fun but it's actually not a bug and the fix is wrong in itself as
  the port may be closing but not yet being destructed, in which case
  it seems to do the wrong thing.  Opening a tty that is closing (and
  could be closing for long periods) is supposed to return -EIO.

  I suspect a better way to deal with this and keep the old console
  timing is to split tty->shutdown into two functions.

  tty->shutdown() - called synchronously just before we dump the tty
  onto the waitqueue for destruction

  tty->cleanup() - called when the destructor runs.

  We would then do the shutdown part which can occur in IRQ context
  fine, before queueing the rest of the release (from tty->magic = 0
  ...  the end) to occur asynchronously

  The USB update in -next would then need a call like

       if (tty->cleanup)
               tty->cleanup(tty);

  at the top of the async function and the USB shutdown to be split
  between shutdown and cleanup as the USB resource cleanup and final
  tidy cannot occur synchronously as it needs to sleep.

  In other words the logic becomes

       final kref put
               make object unfindable

       async
               clean it up

Subject: parisc: tracehook_report_syscall

This makes parisc use the standard tracehook_report_syscall_entry
and tracehook_report_syscall_exit hooks in <linux/tracehook.h>.

To do this, we need to access current->thread.regs, and to know
whether we're entering or exiting the syscall, so add this to
syscall_trace.

Instead of fiddling with gr[20], restructure code to return whether
or not to -ENOSYS. (Also do a bit of fiddling to let them take

Subject: parisc: stop using task->ptrace for {single,block}step flags

task->ptrace flags belong to generic code, so instead thief some
TIF_ bits to use. Somewhat risky conversion of code to test TASK_FLAGS
instead of TASK_PTRACE in assembly, but it looks alright in the end.

Having separate drivers for SPIC showed to be useless, only type3 has a
slightly different behaviour than the others and there seem to be no real
conflict between them.

Subject: sony-laptop: SPIC unset IRQF_SHARED, set IRQF_DISABLED

The SPIC irq is not really shareable, the IO port cannot be cleared and
always returns some data so there is no real way to understand if the irq
is for us or not. Moreover the _PRS acpi method says the irq is not
shareable.
In addition to this, in some cases, an additional write to the IO port has
to be performed in order to properly decode the event received from the
device. This generates another interrupt which may overlap with the
previous one. In the future this is going to be important for properly
decoding events.

Subject: parisc: rename parisc's vmalloc_start to parisc_vmalloc_start

building kernel 2.6.32(pre), gives this compiler warning:
/linus-linux-2.6/mm/vmalloc.c: In function 'pcpu_get_vm_areas':
/linus-linux-2.6/mm/vmalloc.c:2104: warning: 'vmalloc_start' is used
uninitialized in this function

The reason is, that the code in mm/vmalloc defines a local variable called
vmalloc_start, which is already defined as global variable in parisc's code.

To avoid this kind of problems in future, I suggest to rename the parisc
variable
to parisc_vmalloc_start.

Subject: sh: Handle ioport_map() cases for >= P1SEG addresses.

This fixes up the case where certain drivers already do their own
remapping and subsequently attempt to use the PIO calls for I/O. In this
case there is no additional remapping that needs to be done, and the
address can be casted in to the cookie directly.

Subject: sh: Set the default I/O port base to P2SEG.

This bumps up the default I/O base to P2SEG, which allows legacy probing
to bail out gracefully rather than oopsing. Platforms that have a real
PIO offset still need to fix this up on their own, although most
platforms are content with P2SEG already.

The previous change to teach ioport_map() about >= P1SEG offsets in
combination with this patch allows both the already remapped and the
legacy address probing to pass through and succeed.

Fixes up an oops with i8042 on the sh7785lcr board.

There's already code in do_page_fault() to conditionally enable

calling it. This fixes a lockdep warning where we called
trace_hardirqs_off() but with irqs still enabled.

Subject: ARM: Fix SA1100 Neponset serial section mismatch

WARNING: vmlinux.o(.devinit.text+0x524): Section mismatch in reference from the function neponset_probe() to the function .init.text:sa1100_register_uart_fns()
The function __devinit neponset_probe() references
a function __init sa1100_register_uart_fns().
If sa1100_register_uart_fns is only used by neponset_probe then
annotate sa1100_register_uart_fns with a matching annotation.

Subject: ARM: Don't allow highmem on SMP platforms without h/w TLB ops
 broadcast

We suffer an unfortunate combination of "features" which makes highmem
support on platforms without hardware TLB maintainence broadcast difficult:

- we need kmap_high_get() support for DMA cache coherence
- this requires kmap_high() to take a spinlock with IRQs disabled
- kmap_high() occasionally calls flush_all_zero_pkmaps() to clear
  out old mappings
- flush_all_zero_pkmaps() calls flush_tlb_kernel_range(), which
  on s/w IPI'd systems eventually calls smp_call_function_many()
- smp_call_function_many() must not be called with IRQs disabled:

Subject: ARM: Fix __cpuexit section mismatch warnings

Fix:

WARNING: vmlinux.o(.text+0x247c): Section mismatch in reference from the function cpu_idle() to the function .cpuexit.text:cpu_die()
The function cpu_idle() references a function in an exit section.
Often the function cpu_die() has valid usage outside the exit section
and the fix is to remove the __cpuexit annotation of cpu_die.

WARNING: vmlinux.o(.cpuexit.text+0x3c): Section mismatch in reference from the function cpu_die() to the function .cpuinit.text:secondary_start_kernel()
The function __cpuexit cpu_die() references
a function __cpuinit secondary_start_kernel().
This is often seen when error handling in the exit function
uses functionality in the init path.
The fix is often to remove the __cpuinit annotation of
secondary_start_kernel() so it may be used outside an init section.

Sam says:
> The annotation of cpu_die() is wrong.
> To be annotated __cpuexit the function shall:
> - be used in exit context and only in exit context with HOTPLUG_CPU=n
> - be used outside exit context with HOTPLUG_CPU=y

So, this also means __cpu_disable(), __cpu_die() and twd_timer_stop() are
also wrong.  However, removing __cpuexit from cpu_die() creates:

WARNING: vmlinux.o(.text+0x6834): Section mismatch in reference from the function cpu_die() to the function .cpuinit.text:secondary_start_kernel()
The function cpu_die() references
the function __cpuinit secondary_start_kernel().
This is often because cpu_die lacks a __cpuinit
annotation or the annotation of secondary_start_kernel is wrong.

so fix this using __ref.

do_cache_op() uses find_vma() to validate its arguments without holding
any locking.  This means that the VMA could vanish beneath us.  Fix
this by taking a read lock on mmap_sem.

Subject: ax25: Add missing dev_put in ax25_setsockopt

ax25_setsockopt SO_BINDTODEVICE is missing a dev_put call in case of
success.  Re-order code to fix this bug.  While at it also reformat two
lines of code to comply with the Linux coding style.

Initial patch by Jarek Poplawski <jarkao2@gmail.com>.

Subject: ext4: Adjust ext4_da_writepages() to write out larger contiguous
 chunks

Work around problems in the writeback code to force out writebacks in
larger chunks than just 4mb, which is just too small.  This also works
around limitations in the ext4 block allocator, which can't allocate
more than 2048 blocks at a time.  So we need to defeat the round-robin
characteristics of the writeback code and try to write out as many
blocks in one inode before allowing the writeback code to move on to
another inode.  We add a a new per-filesystem tunable,
max_writeback_mb_bump, which caps this to a default of 128mb per
inode.

ext4_da_reserve_space() can reserve quota blocks multiple times if
ext4_claim_free_blocks() fail and we retry the allocation. We should
release the quota reservation before restarting.

Subject: ext4: Split uninitialized extents for direct I/O

When writing into an unitialized extent via direct I/O, and the direct
I/O doesn't exactly cover the unitialized extent, split the extent
into uninitialized and initialized extents before submitting the I/O.
This avoids needing to deal with an ENOSPC error in the end_io
callback that gets used for direct I/O.

When the IO is complete, the written extent will be marked as initialized.

Subject: ext4: Use end_io callback to avoid direct I/O fallback to buffered
 I/O

Currently the DIO VFS code passes create = 0 when writing to the
middle of file.  It does this to avoid block allocation for holes, so
as not to expose stale data out when there is a parallel buffered read
(which does not hold the i_mutex lock).  Direct I/O writes into holes
falls back to buffered IO for this reason.

Since preallocated extents are treated as holes when doing a
get_block() look up (buffer is not mapped), direct IO over fallocate
also falls back to buffered IO.  Thus ext4 actually silently falls
back to buffered IO in above two cases, which is undesirable.

To fix this, this patch creates unitialized extents when a direct I/O
write into holes in sparse files, and registering an end_io callback which
converts the uninitialized extent to an initialized extent after the
I/O is completed.

Subject: ext4: async direct IO for holes and fallocate support

For async direct IO that covers holes or fallocate, the end_io
callback function now queued the convertion work on workqueue but
don't flush the work rightaway as it might take too long to afford.

But when fsync is called after all the data is completed, user expects
the metadata also being updated before fsync returns.

Thus we need to flush the conversion work when fsync() is called.
This patch keep track of a listed of completed async direct io that
has a work queued on workqueue.  When fsync() is called, it will go
through the list and do the conversion.

Subject: bridge: Fix double-free in br_add_if.

There is a potential double-kfree in net/bridge/br_if.c.  If br_fdb_insert
fails, then the kobject is put back (which calls kfree due to the kobject
release), and then kfree is called again on the net_bridge_port.  This
patch fixes the crash.

Thanks to Stephen Hemminger for the one-line fix.

Subject: net: Add explicit bound checks in net/socket.c

The sys_socketcall() function has a very clever system for the copy
size of its arguments. Unfortunately, gcc cannot deal with this in
terms of proving that the copy_from_user() is then always in bounds.
This is the last (well 9th of this series, but last in the kernel) such
case around.

With this patch, we can turn on code to make having the boundary provably
right for the whole kernel, and detect introduction of new security
accidents of this type early on.

Subject: Btrfs: proper -ENOSPC handling

At the start of a transaction we do a btrfs_reserve_metadata_space() and
specify how many items we plan on modifying.  Then once we've done our
modifications and such, just call btrfs_unreserve_metadata_space() for
the same number of items we reserved.

For keeping track of metadata needed for data I've had to add an extent_io op
for when we merge extents.  This lets us track space properly when we are doing
sequential writes, so we don't end up reserving way more metadata space than
what we need.

The only place where the metadata space accounting is not done is in the
relocation code.  This is because Yan is going to be reworking that code in the
near future, so running btrfs-vol -b could still possibly result in a ENOSPC
related panic.  This patch also turns off the metadata_ratio stuff in order to
allow users to more efficiently use their disk space.

This patch makes it so we track how much metadata we need for an inode's
delayed allocation extents by tracking how many extents are currently
waiting for allocation.  It introduces two new callbacks for the
extent_io tree's, merge_extent_hook and split_extent_hook.  These help
us keep track of when we merge delalloc extents together and split them
up.  Reservations are handled prior to any actually dirty'ing occurs,
and then we unreserve after we dirty.

btrfs_unreserve_metadata_for_delalloc() will make the appropriate
unreservations as needed based on the number of reservations we
currently have and the number of extents we currently have.  Doing the
reservation outside of doing any of the actual dirty'ing lets us do
things like filemap_flush() the inode to try and force delalloc to
happen, or as a last resort actually start allocation on all delalloc
inodes in the fs.  This has survived dbench, fs_mark and an fsx torture
test.

Subject: cfg80211: wext: don't display BSSID unless associated

Currently, cfg80211's SIOCGIWAP implementation returns
the BSSID that the user set, even if the connection has
since been dropped due to other changes. It only should
return the current BSSID when actually connected.

Also do a small code cleanup.

Subject: cfg80211: don't set privacy w/o key

When wpa_supplicant is used to connect to open networks,
it causes the wdev->wext.keys to point to key memory, but
that key memory is all empty. Only use privacy when there
is a default key to be used.

Subject: iwlwifi: fix debugfs buffer handling

We keep track of where to write into a buffer by keeping a count of how
much has been written so far. When writing to the buffer we thus take the
buffer pointer and adding the count of what has been written so far.
Keeping track of what has been written so far is done by incrementing
this number every time something is written to the buffer with how much has
been written at that time.

Currently this number is incremented incorrectly when using the
"hex_dump_to_buffer" call to add data to the buffer. Fix this by only
adding what has been added to the buffer in that call instead of what has
been added since beginning of buffer.

Issue was discovered and discussed during testing of
https://bugzilla.redhat.com/show_bug.cgi?id=464598 .

When a user views any of these files they will see something like:

Subject: iwlwifi: fix 3945 ucode info retrieval after failure

When hardware or uCode problem occurs driver captures significant
information from device to enable debugging. The format of this information
is different between 3945 and 4965 and later devices, yet currently the
3945 uses the 4965 and later format. Fix this by adding a new library call
that is initialized to the correct formatting routine based on device.

This moves the iwlagn event and error log handling back to iwl-agn.c to
make it part of iwlagn module.

Also remove the 3945 sysfs file that triggers dump of event log - there is
already a debugfs file that can do it for all drivers.

Subject: cfg80211: always get BSS

Multiple problems were reported due to interaction
between wpa_supplicant and the wext compat code in
cfg80211, which appear to be due to it not getting
any bss pointer here when wpa_supplicant sets all
parameters -- do that now. We should still get the
bss after doing an extra scan, but that appears to
increase the time we need for connecting enough to
sometimes cause timeouts.

Subject: wext: Add bound checks for copy_from_user

The wireless extensions have a copy_from_user to a local stack
array "essid", but both me and gcc have failed to find where
the bounds for this copy are located in the code.

This patch adds some basic sanity checks for the copy length
to make sure that we don't overflow the stack buffer.

Subject: wext: add back wireless/ dir in sysfs for cfg80211 interfaces

The move away from having drivers assign wireless handlers,
in favour of making cfg80211 assign them, broke the sysfs
registration (the wireless/ dir went missing) because the
handlers are now assigned only after registration, which is
too late.

Fix this by special-casing cfg80211-based devices, all
of which are required to have an ieee80211_ptr, in the
sysfs code, and also using get_wireless_stats() to have
the same values reported as in procfs.

Subject: sony-laptop: check for rfkill hard block at load time

"I recently (on a flight) I found out that when I boot with the hard-switch
activated, so turning off all wireless activity on my laptop, the state
is not correctly announced in /dev/rfkill (reading it with rfkill command,
or my own gnome applet)...

After turning off and on again the hard-switch the events were right."

We can fix this by querying the firmware at load time and calling
rfkill_set_hw_state().

Subject: PM / yenta: Fix cardbus suspend/resume regression

Since 2.6.29 the PCI PM core have been restoring the standard
configuration registers of PCI devices in the early phase of
resume.  In particular, PCI devices without drivers have been handled
this way since commit 355a72d75b3b4f4877db4c9070c798238028ecb5
(PCI: Rework default handling of suspend and resume).  Unfortunately,
this leads to post-resume problems with CardBus devices which cannot
be accessed in the early phase of resume, because the sockets they
are on have not been woken up yet at that point.

To solve this problem, move the yenta socket resume to the early
phase of resume and, analogously, move the suspend of it to the late
phase of suspend.  Additionally, remove some unnecessary PCI code
from the yenta socket's resume routine.

Fixes http://bugzilla.kernel.org/show_bug.cgi?id=13092, which is a
post-2.6.28 regression.

Subject: drm/i915: Don't call intel_update_fbc from intel_crtc_cursor_set

Commit 74dff282 exposed this unnecessary call by causing a change in
the failure path on i965 where framebuffer compression will be turned
on and off on every cursor update. If you don't have the xf86-video-intel
fix to avoid the blinking cursor effect, this is very slow.

Symptoms were a far more noticeable cursor blink with every cursor image
change combined with severe slowdown for animated cursors.

Subject: percpu: fix unit_map[] verification in pcpu_setup_first_chunk()

pcpu_setup_first_chunk() incorrectly used NR_CPUS as the impossible
unit number while unit number can equal and go over NR_CPUS with
sparse unit map.  This triggers BUG_ON() spuriously on machines which
have non-power-of-two number of cpus.  Use UINT_MAX instead.

Subject: sparc64: implement page mapping percpu first chunk allocator

Implement page mapping percpu first chunk allocator as a fallback to
the embedding allocator.  The next patch will make the embedding
allocator check distances between units to determine whether it fits
within the vmalloc area so that this fallback can be used on such
cases.

sparc64 currently has relatively small vmalloc area which makes it
impossible to create any dynamic chunks on certain configurations
leading to percpu allocation failures.  This and the next patch should
allow those configurations to keep working until proper solution is
found.

While at it, mark pcpu_cpu_distance() with __init.

Subject: percpu: make embedding first chunk allocator check vmalloc space size

Embedding first chunk allocator maintains the distances between units
in the vmalloc area and thus needs vmalloc space to be larger than the
maximum distances between units; otherwise, it wouldn't be able to
create any dynamic chunks.  This patch makes the embedding first chunk
allocator check vmalloc space size and if the maximum distance between
units is larger than 75% of it, print warning and, if page mapping
allocator is available, fail initialization so that the system falls
back onto it.

This should work around percpu allocation failure problems on certain
sparc64 configurations where distances between NUMA nodes are larger
than the vmalloc area and makes percpu allocator more robust for
future configurations.

Subject: percpu: make pcpu_setup_first_chunk() failures more verbose

The parameters to pcpu_setup_first_chunk() come from different sources
depending on architecture and can be quite complex.  The function runs
various sanity checks on the parameters and triggers BUG() if
something isn't right.  However, this is very early during the boot
and not reporting exactly what the problem is makes debugging even
harder.

Add PCPU_SETUP_BUG() macro which prints out enough information about
the parameters.  As the macro still puts separate BUG() for each
check, it won't lose any information even on the situations where only
the program counter can be retrieved.

While at it, also bump pcpu_dump_alloc_info() message to KERN_INFO so
that it's visible on the console if boot fails to complete.

Subject: percpu: make allocation failures more verbose

Warn and dump stack when percpu allocation fails.  percpu allocator is
still young and unchecked NULL percpu pointer usage can result in
random memory corruption when combined with the pointer shifting in
access macros.  Allocation failures should be rare and the warning
message will be disabled after certain times.

Subject: drm: fix drm_fb_helper warning when !CONFIG_MAGIC_SYSRQ

Compiling DRM throws the following warning if MAGIC_SYSRQ is disabled:

drivers/gpu/drm/drm_fb_helper.c:101: warning: 'sysrq_drm_fb_helper_restore_op' defined but not used

Fix: place sysrq_drm_fb_helper_restore_op and associated
definitions inside #ifdef CONFIG_MAGIC_SYSRQ.

Subject: drm: fix radeon DRM warnings when !CONFIG_DEBUG_FS

Compiling the radeon DRM driver with !CONFIG_DEBUG_FS
throws the following warnings:

drivers/gpu/drm/radeon/radeon_ttm.c: In function 'radeon_ttm_debugfs_init':
drivers/gpu/drm/radeon/radeon_ttm.c:714: warning: unused variable 'i'
drivers/gpu/drm/radeon/radeon_ttm.c: At top level:
drivers/gpu/drm/radeon/radeon_ttm.c:692: warning: 'radeon_mem_types_list' defined but not used
drivers/gpu/drm/radeon/radeon_ttm.c:693: warning: 'radeon_mem_types_names' defined but not used

Fix: move these variables inside the #if defined(CONFIG_DEBUG_FS)
block in radeon_ttm_debugsfs_init(), which is the only place using them.

Convert the rv515 asic support to new init path also add an explanation
in radeon.h about the new init path. There is also few cleanups
associated with this change (others asic calling rv515 helper
functions).

Subject: drm/radeon/kms: Convert R520 to new init path and associated cleanup

Convert the r520 asic support to new init path, change are smaller than
previous one as most of the architecture is now in place and more code
sharing can happen btw various asics.

Subject: drm/i915: batch submit seqno off-by-one.

We increment the seqno number between submitting the batch buffer and
the flush/interrupt that demarcates its end, so the tracepoint needs to
reference the incremented value to match the completion event.

Subject: drm/i915: Enable irq to trace batch buffer completion.

If we trigger a tracepoint for batch buffer submission, it is a reasonable
assumption that we wish to also trace the batch buffer completion. So in
order to capture the completion events, we need to enable irqs... However,
we cannot rely on the completion event to disable the irq later, so we
defer the irq disable to the retire request.

Subject: nilfs2: fix missing zero-fill initialization of btree node cache

This will fix file system corruption which infrequently happens after
mount.  The problem was reported from users with the title "[NILFS
users] Fail to mount NILFS." (Message-ID:
<200908211918.34720.yuri@itinteg.net>), and so forth.  I've also
experienced the corruption multiple times on kernel 2.6.30 and 2.6.31.

The problem turned out to be caused due to discordance between
mapping->nrpages of a btree node cache and the actual number of pages
hung on the cache; if the mapping->nrpages becomes zero even as it has
pages, truncate_inode_pages() returns without doing anything.  Usually
this is harmless except it may cause page leak, but garbage collection
fairly infrequently sees a stale page remained in the btree node cache
of DAT (i.e. disk address translation file of nilfs), and induces the
corruption.

I identified a missing initialization in btree node caches was the
root cause.  This corrects the bug.

I've tested this for kernel 2.6.30 and 2.6.31.

Subject: nilfs2: fix missing initialization of i_dir_start_lookup member

The i_dir_start_lookup field in nilfs_inode_info objects should be
cleared when the objects are allocated, but the the initialization was
missing in case of reading from disk.  This adds the initialization.

Since the variable just gives a start page on directory lookups, the
bug was nonfatal until now.

Subject: ext4: Avoid updating the inode table bh twice in no journal mode

This is a cleanup of commit 91ac6f4.  Since ext4_mark_inode_dirty()
has already called ext4_mark_iloc_dirty(), which in turn calls
ext4_do_update_inode(), it's not necessary to have ext4_write_inode()
call ext4_do_update_inode() in no journal mode.  Indeed, it would be
duplicated work.

This patch a problem that ext4_dirty_inode() was not calling
ext4_mark_inode_dirty() if the current_handle is not valid, which it
is the case in no journal mode.

It also removes a test for non-matching transaction which can never
happen.

Subject: Btrfs: Fix setting umask when POSIX ACLs are not enabled

We currently set sb->s_flags |= MS_POSIXACL unconditionally, which is
incorrect -- it tells the VFS that it shouldn't set umask because we
will, yet we don't set it ourselves if we aren't using POSIX ACLs, so
the umask ends up ignored.

Subject: ext4, jbd2: Drop unneeded printks at mount and unmount time

There are a number of kernel printk's which are printed when an ext4
filesystem is mounted and unmounted.  Disable them to economize space
in the system logs.  In addition, disabling the mballoc stats by
default saves a number of unneeded atomic operations for every block
allocation or deallocation.

Subject: mac80211: Fix [re]association power saving issue on AP side

Consider the following step-by step:
1. A STA authenticates and associates with the AP and exchanges
traffic.
2. The STA reports to the AP that it is going to PS state.
3. Some time later the STA device goes to the stand-by mode (not only
its wi-fi card, but the device itself) and drops the association state
without sending a disassociation frame.
4. The STA device wakes up and begins authentication with an
Auth frame as it hasn't been authenticated/associated previously.

At the step 4 the AP "remembers" the STA and considers it is still in
the PS state, so the AP buffers frames, which it has to send to the STA.
But the STA isn't actually in the PS state and so it neither checks
TIM bits nor reports to the AP that it isn't power saving.
Because of that authentication/[re]association fails.

To fix authentication/[re]association stage of this issue, Auth, Assoc
Resp and Reassoc Resp frames are transmitted disregarding of STA's power
saving state.

N.B. This patch doesn't fix further data frame exchange after
authentication/[re]association. A patch in hostapd is required to fix
that.

On SDIO the PIO data register seems to be hardwired to LE. So
the MACCTL bit has no effect on the endianness.
So also use block-I/O for the last word of the packet. block-I/O is always LE.

Subject: mac80211_hwsim: Fix initial beacon timer configuration

mac80211_hwsim does not start transmitting Beacon frames when hostapd
is started for the first time and restarting hostapd fixes this. The
issue is caused by the config() handler not being able to start
beacon_timer when beacon interval is not yet known and
bss_info_changed() handler not starting the timer. This can be fixed by
making the bss_info_changed() update the timer.

Subject: ar9170: fix bug in iq-auto calibration value calculation

This patch fixes a embarrassing bug which was introduced by:
"[PATCH] ar9170: implement frequency calibration for one-stage/openfw"

The phy_data variable initialization has to done outside the for-loop
scope. This is because the for-loop uses u32 phy_data variable more
like a 4-byte field. But in each run only a single byte is calculated.
Therefore phy_data content needs to stay the same for at least 3 more
iterations, before the complete set can be uploaded.

Subject: Btrfs: fix deadlock with free space handling and user transactions

If an ioctl-initiated transaction is open, we can't force a commit during
the free space checks in order to free up pinned extents or else we
deadlock.  Just ENOSPC instead.

A more satisfying solution that reserves space for the entire user
transaction up front is forthcoming...

The /proc/fs/ext4/<dev>/mb_history was maintained manually, and had a
number of problems: it required a largish amount of memory to be
allocated for each ext4 filesystem, and the s_mb_history_lock
introduced a CPU contention problem.

By ripping out the mb_history code and replacing it with ftrace
tracepoints, and we get more functionality: timestamps, event
filtering, the ability to correlate mballoc history with other ext4
tracepoints, etc.

From bf6993276f74d46776f35c45ddef29b981b1d1c6 Mon Sep 17 00:00:00 2001
From: Theodore Ts'o <tytso@mit.edu>
Date: Wed, 30 Sep 2009 00:32:06 -0400
Subject: jbd2: Use tracepoints for history file

The /proc/fs/jbd2/<dev>/history was maintained manually; by using
tracepoints, we can get all of the existing functionality of the /proc
file plus extra capabilities thanks to the ftrace infrastructure.  We
save memory as a bonus.

Subject: ext4: Add a stub for mpage_da_data in the trace header

The tracepoint ext4_da_write_pages has a struct mpage_da_data*
parameter, but that struct is only defined in fs/ext4/ext4.h.  This
patch adds a forward declaration for that struct, so this tracepoint
header can still be used by tools like SystemTap.

This is a continuation of the fix in commit 3661d286.

Subject: sh: Disable unaligned kernel access printks by default.

Certain networking and USB workloads generate floods of these accesses,
so just disable it by default (thereby restoring the old behaviour). The
option remains configurable from userspace, and can still be used as a
debugging aid.

Subject: ext4: Fix time encoding with extra epoch bits

"Looking at ext4.h, I think the setting of extra time fields forgets to
mask the epoch bits so the epoch part overwrites nsec part. The second
change is only for coherency (2 -> EXT4_EPOCH_BITS)."

Thanks to Damien Guibouret for pointing out this problem.

This reverts commit 22223c9b417be5fd0ab2cf9ad17eb7bd1e19f7b9, as
requested by Andi Kleen:

  "Obviously kernels compiled with AMD support can still run on non AMD
   systems, so messages like this can never be removed at compile time."

Subject: pty: reconnect the BSD TIOCSPTLCK handling to legacy ptys

David Howells noticed (due to the compiler warning about an unused
'pty_ops_bsd' variable) that we haven't actually been using the code
that implements TIOCSPTLCK for legacy pty handling.  It's been that way
since 2.6.26, commit 3e8e88ca053150efdbecb45d8f481cf560ec808d to be
exact ("pty: prepare for tty->ops changes").

DavidH initially submitted a patch just removing the dead code entirely,
and since nobody has apparently ever complained, I'm not entirely sure
that wouldn't be the right thing to do.  But since the whole and only
point of the legacy pty code is to be compatible with legacy distros
that don't use the new unix98 pty model, let's just wire it up again.

And clean it up a bit while we're at it.

Subject: intel-iommu: Yet another BIOS workaround: Isoch DMAR unit with no TLB
 space

Asus decided to ship a BIOS which configures sound DMA to go via the
dedicated IOMMU unit, but assigns precisely zero TLB entries to that
unit. Which causes the whole thing to deadlock, including the DMA
traffic on the _other_ IOMMU units. Nice one.

Subject: dlm: fix lowcomms_connect_node for sctp

The recently added dlm_lowcomms_connect_node() from
391fbdc5d527149578490db2f1619951d91f3561 does not work
when using SCTP instead of TCP.  The sctp connection code
has nothing to do without data to send.  Check for no data
in the sctp connection code and do nothing instead of
triggering a BUG.  Also have connect_node() do nothing
when the protocol is sctp.

Subject: dlm: fix socket fd translation

The code to set up sctp sockets was not using the sockfd_lookup()
and sockfd_put() routines to translate an fd to a socket.  The
direct fget and fput calls were resulting in error messages from
alloc_fd().

Also clean up two log messages and remove a third, related to
setting up sctp associations.

Subject: MIPS: SMTC: Remove duplicate structure field initialization

The definition of the irq_ipi structure has two initializations of the
flags field.  This combines them.

[Ralf: The issue was originally introduced by commit
be4894196d79455f420dd7bb78be7dc73bec115c (linux-mips.org) rsp.
033890b084adfa367c544864451d7730552ce8bf (kernel.org).  The original
intention of the code was to initialize .flags with both flags ored together.
The broken C code as actually implemented will be compiled by an equally
broken gcc to use only the last initialization, that is IRQF_PERCPU
which means this turned into an SMTC bug for 2.6.23 and newer.]

The semantic match that finds this problem is as follows:

Subject: MIPS: BCM1480: Re-apply patch lost due to bad resolution of merge
 conflict.

Patch 14275ccdb1e4b487cca745aba994699c426a31ee and
d5dedd4507d307eb3f35f21b6e16f336fdc0d82a are conflicting and the
conflict was resolved badly in merge
92241940be501f798cb21db344bbb3d1ec3c4f1c resulting in the BCM1480 changes
of 14275ccdb1e4b487cca745aba994699c426a31ee getting lost.  Sort out the
damage.

Reported and initial patch by Mark Mason <mmason@upwardaccess.com>.

Subject: MIPS: Decrease size of au1xxx_dbdma_pm_regs[][]

There are 16 individual channels (NUM_DBDMA_CHANS) to save/restore plus the
global ddma block config (the +1).  The last register in a channel can be
skipped since it's read-only (at offset 0x18).

Subject: x86: Provide an alternative() based cmpxchg64()

cmpxchg64() today generates, to quote Linus, "barf bag" code.

cmpxchg64() is about to get used in the scheduler to fix a bug there,
but it's a prerequisite that cmpxchg64() first be made non-sucking.

This patch turns cmpxchg64() into an efficient implementation that
uses the alternative() mechanism to just use the raw instruction on
all modern systems.

Note: the fallback is NOT smp safe, just like the current fallback
is not SMP safe. (Interested parties with i486 based SMP systems
are welcome to submit fix patches for that.)

Subject: sched_clock: Fix atomicity/continuity bug by using cmpxchg64()

Commit def0a9b2573 (sched_clock: Make it NMI safe) assumed
cmpxchg() of 64bit values was available on X86_32.

That is not so - and causes some subtle scheduler misbehavior due
to incorrect timestamps off to up by ~4 seconds.

Two symptoms are known right now:

 - interactivity problems seen by Arjan: up to 600 msecs
   latencies instead of the expected 20-40 msecs. These
   latencies are very visible on the desktop.

 - incorrect CPU stats: occasionally too high percentages in 'top',
   and crazy CPU usage stats.

Subject: net: Make setsockopt() optlen be unsigned.

This provides safety against negative optlen at the type
level instead of depending upon (sometimes non-trivial)
checks against this sprinkled all over the the place, in
each and every implementation.

Based upon work done by Arjan van de Ven and feedback
from Linus Torvalds.

Subject: net: Fix sock_wfree() race

Commit 2b85a34e911bf483c27cfdd124aeb1605145dc80
(net: No more expensive sock_hold()/sock_put() on each tx)
opens a window in sock_wfree() where another cpu
might free the socket we are working on.

A fix is to call sk->sk_write_space(sk) while still
holding a reference on sk.

Subject: sit: fix off-by-one in ipip6_tunnel_get_prl

When requesting all prl entries (kprl.addr == INADDR_ANY) and there are
more prl entries than there is space passed from userspace, the existing
code would always copy cmax+1 entries, which is more than can be handled.

This patch makes the kernel copy only exactly cmax entries.

Subject: net: restore tx timestamping for accelerated vlans

Since commit 9b22ea560957de1484e6b3e8538f7eef202e3596
( net: fix packet socket delivery in rx irq handler )

We lost rx timestamping of packets received on accelerated vlans.

Effect is that tcpdump on real dev can show strange timings, since it gets rx timestamps
too late (ie at skb dequeueing time, not at skb queueing time)

In ext4_num_dirty_pages() we were calling page_buffers() before

Subject: ixgbe: Fix disabling of relaxed ordering with Tx DCA

82599 has a different register offset for the Tx DCA control registers.
We disable relaxed ordering of the descriptor writebacks for Tx head
writeback, but didn't disable it properly for 82599.  However, this
shouldn't be a visible issue, since ixgbe doesn't use Tx head writeback.
This patch just makes sure we're not doing blind writes to offsets we
don't expect.

Subject: ixgbe patch to provide NIC's tx/rx counters via ethtool

When LRO is enabled, the received packet and byte counters represent the
LRO'd packets, not the packets/bytes on the wire.  The Intel 82599 NIC has
registers that keep count of the physical packets.  Add these counters to
the ethtool stats.  The byte counters are 36-bit, but the high 4 bits were
being ignored in the 2.6.31 ixgbe driver:  Read those as well to allow
longer time between polling the stats to detect wraps.

Subject: ixgbe: Remove ATR computation for UDP traffic

ATR support for UDP on 82599 needs to be redesigned, since the
current model doesn't make much sense.  The fallout from having
it in though is it causes all UDP traffic to still compute the
ATR hashes on transmit, which are useless.  This removal will
return upwards of 10% of relative computational overhead in
forwarding tests.

If allocation of the second ports fails, make sure that hw->ports

This fix is copied from a similar fix in the sky2 driver (ca519274...),
but is untested, as I don't have a skge card.

Subject: 3c59x: Rework suspend and resume

As noticed by Alan Stern, there is still one issue with the driver:
we disable PCI IRQ on suspend, but other devices on the same IRQ
line might still need the IRQ enabled to suspend properly.

Nowadays, PCI core handles all power management work by itself, with
one condition though: if we use dev_pm_ops. So, rework the driver to
only quiesce 3c59x internal logic on suspend, while PCI core will
manage PCI device power state with IRQs disabled.

Subject: be2net: Workaround to fix a bug in Rx Completion processing.

vtp bit in RX completion descriptor could be wrongly set in
some skews of BladEngine.  Ignore this  bit if vtm is not set.
Resending because the previous patch was against net-next tree.
This patch is against the net-2.6 tree.

Subject: ALSA: Don't assume i2c device probing always succeeds

The client->driver pointer can be NULL when i2c-device probing fails
in i2c_new_device().  This patch adds the NULL checks for client->driver
and return the error instead of blind assumption of driver availability.

Subject: x86: Optimize cmpxchg64() at build-time some more

Try to avoid the 'alternates()' code when we can statically
determine that cmpxchg8b is fine. We already have that
CONFIG_x86_CMPXCHG64 (enabled by PAE support), and we could easily
also enable it for some of the CPU cases.

Note, this patch only adds CMPXCHG8B for the obvious Intel CPU's,
not for others. (There was something really messy about cmpxchg8b
and clone CPU's, so if you enable it on other CPUs later, do it
carefully.)

If we avoid that asm-alternative thing when we can assume the
instruction exists, we'll generate less support crud, and we'll
avoid the whole issue with that extra 'nop' for padding instruction
sizes etc.

Subject: x86: Fix csum_ipv6_magic asm memory clobber

Just like ip_fast_csum, the assembly snippet in csum_ipv6_magic needs a
memory clobber, as it is only passed the address of the buffer, not a
memory reference to the buffer itself.

This caused failures in Hurd's pfinetv4 when we tried to compile it with
gcc-4.3 (bogus checksums).

Subject: tracing: Fix infinite recursion in ftrace_update_pid_func()

When CONFIG_HAVE_FUNCTION_TRACE_MCOUNT_TEST is enabled
__ftrace_trace_function contains the current trace function, not
ftrace_trace_function.

In ftrace_update_pid_func() we currently incorrectly assign the
value of ftrace_trace_function to __ftrace_trace_funcion before
returning.

Without this patch it is possible to execute an infinite recursion
whereby ftrace_test_stop_func() calls __ftrace_trace_function,
which was assigned ftrace_test_stop_func() in
ftrace_update_pid_func().

Subject: perf timechart: Add a power-only mode

For doing work on the Linux power management components, I need to
make long (30+ seconds) traces. Currently, this then results in a
HUGE svg file, with mostly process data that isn't interesting.

This patch adds a --power-only mode to perf timechart that only
outputs the CPU power section of the SVG; this significantly
reduces the size of the SVG file, making even 30+ second traces
viewable with inkscape.

As a minor tweak for the same effect, the minimum text size is
decreased; current inkscape cannot zoom in deep enough to show text
this small, but it reduces inkscape compute time.

Subject: perf_event: Fix event group handling in __perf_event_sched_*()

Paul Mackerras says:

 "Actually, looking at this more closely, it has to be a group
 leader anyway since it's at the top level of ctx->group_list.  In
 fact I see four places where we do:

  list_for_each_entry(event, &ctx->group_list, group_entry) {
	if (event == event->group_leader)
		...

 or the equivalent, three of which appear to have been introduced
 by afedadf2 ("perf_counter: Optimize sched in/out of counters")
 back in May by Peter Z.

 As far as I can see the if () is superfluous in each case (a
 singleton event will be a group of 1 and will have its
 group_leader pointing to itself)."

 [ See: http://marc.info/?l=linux-kernel&m=125361238901442&w=2 ]

And Peter Zijlstra points out this is a bugfix:

 "The intent was to call event_sched_{in,out}() for single event
  groups because that's cheaper than group_sched_{in,out}(),
  however..

  - as you noticed, I got the condition wrong, it should have read:

      list_empty(&event->sibling_list)

  - it failed to call group_can_go_on() which deals with ->exclusive.

  - it also doesn't call hw_perf_group_sched_in() which might break
    power."

 [ See: http://marc.info/?l=linux-kernel&m=125369523318583&w=2 ]

Changelog v1->v2:

 - Fix the title name according to Peter Zijlstra's suggestion

 - Remove the comments and WARN_ON_ONCE() as Peter Zijlstra's
   suggestion

Subject: x86: earlyprintk: Fix regression to handle serial,ttySn as 1 arg

Commit c953094 ("early_printk: Allow more than one early console")
introduced a regression in the parsing of the earlyprintk= kernel
arguments.

If you specify "earlyprintk=serial,ttyS0,115200" as a kernel
argument, the "serial,ttyS" should be parsed as a single argument
and not as "serial" and then "ttyS".

Also update the documentation to reflect you can specify the ttyS
directly without the "serial" argument.

Subject: x86: Don't leak 64-bit kernel register values to 32-bit processes

While 32-bit processes can't directly access R8...R15, they can
gain access to these registers by temporarily switching themselves
into 64-bit mode.

Therefore, registers not preserved anyway by called C functions
(i.e. R8...R11) must be cleared prior to returning to user mode.

Subject: kmemtrace: Fix up tracer registration

Commit ddc1637af217dbd8bc51f30e6d24e84476a869a6 ("kmemtrace: Print
binary output only if 'bin' option is set") ended up inverting the
error detection logic. register_tracer() returns 0 on success,
which this change caused to treat as an error, resulting in:

[    0.132000] Warning: could not register the kmem tracer

as well as bailing out of the initcall with an error value. This
restores the old logic.

they depend on, so kconfig is unable to display the proper tree.  So sort
the options such they expand/collapse properly.

Subject: HID: fix kerneldoc comment for hid_input_report()

The kerneldoc comment for 'interrupt' has already confused a lot
of people, as it is simply wrong. It doesn't carry the information
about the context, but is used to distinguish between two fundamental
types of low-level transport transfers -- interrupt vs. control.

Make this clear in the comment.

When the auto-mic switching between an analog and a digital mic is
needed with IDT codecs, the current driver doesn't reset the connection
of the digital mux.

This patch fixes the behavior by checking both mux connections properly.

Subject: ARM: 5733/1: fix bcmring compile error

The movement of the MMCI header file made bcmring break. It turns
out it was including asm/mmc.h without using it so fixing the
problem boils down to removing the offending include.

Subject: ARM: 5734/1: arm: fix compilation of entry-common.S for older CPUs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Commit 181f817eaaca4c1f introduced some new code to entry-common.S
Sadly, this new code uses 'bx' instruction which is available only on
ARMv5 and higher CPUs. This causes following compilation errors when
building kernel for StrongARM (ARMv4):

arch/arm/kernel/entry-common.S: Assembler messages:
arch/arm/kernel/entry-common.S:129: Error: selected processor does not
 support `bx ip'
arch/arm/kernel/entry-common.S:138: Error: selected processor does not
 support `bx ip'

Fix these errors by using 'mov pc' instead of 'bx'.

Subject: Btrfs: take i_mutex before generic_write_checks

btrfs_file_write was incorrectly calling generic_write_checks without
taking i_mutex.  This lead to problems with racing around i_size when
doing O_APPEND writes.

The fix here is to move i_mutex higher.

Subject: pktgen: Fix delay handling

After last pktgen changes, delay handling is wrong.

pktgen actually sends packets at full line speed.

Fix is to update pkt_dev->next_tx even if spin() returns early,
so that next spin() calls have a chance to see a positive delay.

Subject: Btrfs: remove duplicates of filemap_ helpers

Use filemap_fdatawrite_range and filemap_fdatawait_range instead of
local copies of the functions.  For filemap_fdatawait_range that
also means replacing the awkward old wait_on_page_writeback_range
calling convention with the regular filemap byte offsets.

Subject: cciss: Use one scan thread per controller and fix hang during rmmod

Replace the use of one scan kthread per controller with one per driver.
Use a queue to hold a list of controllers that need to be rescanned with
routines to add and remove controllers from the queue.

Fix locking and completion handling to prevent a hang during rmmod.

Subject: cciss: Handle special case for sysfs attributes of the first logical
 drive.

For c0dx where x is not 0, we handle deletion and addition simply,
but for c0d0, there is the special case that even when there's no
disk, the device node exists so that the controller may be accessed.
So, for c0d0, we only create the sysfs entries once, when a controller
is added, and only remove them once, when a controller is being
taken down.

Subject: cciss: Fix usage_count check in rebuild_lun_table when triggered via

When rebuild_lun_table is reached via sysfs, the usage count that
is checked prior to messing with c0d0 has different constraints
(must be zero) than if rebuild_lun_table is reached via ioctl
(must be one.)  Fix rebuild_lun_table to take that into account.

Subject: cciss: Preserve all 8 bytes of LUN ID for logical drives.

Preserve all 8 bytes of the LunID field returned
by CCISS_REPORT_LOGICAL instead of only saving 4 bytes.
This fixes a bug with logical volume addressing encountered on
an MSA2012.

Subject: cciss: Don't check h->busy_initializing in cciss_open().

Don't check h->busy_initializing in cciss_open().  Open won't be
called before things are ready, but h->busy_initializing won't be
unset until after the initial rebuild_lun_table is finished.  But,
to read the partitions, cciss_open will be called for each logical
drive during rebuild_lun_table.  If cciss_open checks h->busy_initializing,
then the reading of the partition information during the initial
rebuild_lun_table will fail, which is especially bad news if it
happens to be your boot device.

Subject: cciss: Dynamically allocate the drive_info_struct for each logical
 drive.

cciss: Dynamically allocate the drive_info_struct for each logical drive.
This reduces the size of the per-hba ctlr_info structure from 106936
bytes to 8132 bytes.  That's on 32-bit systems.  On 64-bit systems, the
improvement is even bigger.  Without this, the ctlr_info struct is so big
that the driver won't even load on a 64 bit system if CISS_MAX_LUN was
at it's current setting of 1024 logical drives.

Subject: block: Set max_sectors correctly for stacking devices

The topology changes unintentionally caused SAFE_MAX_SECTORS to be set
for stacking devices.  Set the default limit to BLK_DEF_MAX_SECTORS and
provide SAFE_MAX_SECTORS in blk_queue_make_request() for legacy hw
drivers that depend on the old behavior.

Stacking devices do not have an inherent max_hw_sector limit.  Set the
default to INT_MAX so we are bounded only by capabilities of the
underlying storage.

Add missing blk_trace_remove_sysfs to be in pair with blk_trace_init_sysfs
introduced in commit 1d54ad6da9192fed5dd3b60224d9f2dfea0dcd82.
Release kobject also in case the request_fn is NULL.

Problem was noticed via kmemleak backtrace when some sysfs entries were

Subject: swapfile: avoid NULL pointer dereference in swapon when s_bdev is
 NULL

While testing Swap over NFS patchset, I noticed an oops that was triggered
during swapon. Investigating further, the NULL pointer deference is due to the
SSD device check/optimization in the swapon code that assumes s_bdev could never
be NULL.

inode->i_sb->s_bdev could be NULL in a few cases. For e.g. one such case is
loopback NFS mount, there could be others as well. Fix this by ensuring s_bdev
is not NULL before we try to deference s_bdev.

Subject: block: use normal I/O path for discard requests

prepare_discard_fn() was being called in a place where memory allocation
was effectively impossible.  This makes it inappropriate for all but
the most trivial translations of Linux's DISCARD operation to the block
command set.  Additionally adding a payload there makes the ownership
of the bio backing unclear as it's now allocated by the device driver
and not the submitter as usual.

It is replaced with QUEUE_FLAG_DISCARD which is used to indicate whether
the queue supports discard operations or not.  blkdev_issue_discard now
allocates a one-page, sector-length payload which is the right thing
for the common ATA and SCSI implementations.

The mtd implementation of prepare_discard_fn() is replaced with simply
checking for the request being a discard.

Largely based on a previous patch from Matthew Wilcox <matthew@wil.cx>
which did the prepare_discard_fn but not the different payload allocation
yet.

Subject: block: allow large discard requests

Currently we set the bio size to the byte equivalent of the blocks to
be trimmed when submitting the initial DISCARD ioctl.  That means it
is subject to the max_hw_sectors limitation of the HBA which is
much lower than the size of a DISCARD request we can support.
Add a separate max_discard_sectors tunable to limit the size for discard
requests.

We limit the max discard request size in bytes to 32bit as that is the
limit for bio->bi_size.  This could be much larger if we had a way to pass
that information through the block layer.

Subject: Add a tracepoint for block request remapping

Since 2.6.31 now has request-based device-mapper, it's useful to have
a tracepoint for request-remapping as well as bio-remapping.
This patch adds a tracepoint for request-remapping, trace_block_rq_remap().

Subject: Btrfs: fix data space leak fix

There is a problem where page_mkwrite can be called on a dirtied page that
already has a delalloc range associated with it.  The fix is to clear any
delalloc bits for the range we are dirtying so the space accounting gets
handled properly.  This is the same thing we do in the normal write case, so we
are consistent across the board.  With this patch we no longer leak reserved
space.

Subject: bonding: set primary param via sysfs

Primary module parameter passed to bonding is pernament. That means if you
release the primary slave and enslave it again, it becomes the primary slave
again. But if you set primary slave via sysfs, the primary slave is only set
once and it's not remembered in bond->params structure. Therefore the setting is
lost after releasing the primary slave. This simple one-liner fixes this.

Subject: IPv4 TCP fails to send window scale option when window scale is zero

Acknowledge TCP window scale support by inserting the proper option in SYN/ACK
and SYN headers even if our window scale is zero.

This fixes the following observed behavior:

1. Client sends a SYN with TCP window scaling option and non zero window scale
value to a Linux box.
2. Linux box notes large receive window from client.
3. Linux decides on a zero value of window scale for its part.
4. Due to compare against requested window scale size option, Linux does not to
 send windows scale TCP option header on SYN/ACK at all.

With the following result:

Client box thinks TCP window scaling is not supported, since SYN/ACK had no
TCP window scale option, while Linux thinks that TCP window scaling is
supported (and scale might be non zero), since SYN had  TCP window scale
option and we have a mismatched idea between the client and server
regarding window sizes.

Probably it also fixes up the following bug (not observed in practice):

1. Linux box opens TCP connection to some server.
2. Linux decides on zero value of window scale.
3. Due to compare against computed window scale size option, Linux does
not to set windows scale TCP  option header on SYN.

With the expected result that the server OS does not use window scale option
due to not receiving such an option in the SYN headers, leading to suboptimal
performance.

Subject: skge: use unique IRQ name

Most network drivers request their IRQ when the interface is activated.
skge does it in ->probe() instead, because it can work with two-port
cards where the two net_devices use the same IRQ. This works fine most
of the time, except in some situations when the interface gets renamed.
Consider this example:

1. modprobe skge
   The card is detected as eth0 and requests IRQ 17. Directory
   /proc/irq/17/eth0 is created.
2. There is an udev rule which says this interface should be called
   eth1, so udev renames eth0 -> eth1.
3. modprobe 8139too
   The Realtek card is detected as eth0. It will be using IRQ 17 too.
4. ip link set eth0 up
   Now 8139too requests IRQ 17.

The result is:
WARNING: at fs/proc/generic.c:590 proc_register ...
proc_dir_entry '17/eth0' already registered
...
And "ls /proc/irq/17" shows two subdirectories, both called eth0.

Fix it by using a unique name for skge's IRQ, based on the PCI address.
The naming from the example then looks like this:
$ grep skge /proc/interrupts
 17:        169   IO-APIC-fasteoi   skge@pci:0000:00:0a.0, eth0

irqbalance daemon will have to be taught to recognize "skge@" as an
Ethernet interrupt. This will be a one-liner addition in classify.c. I
will send a patch to irqbalance if this change is accepted.

Subject: sky2: irqname based on pci address

This is based on Michal Schmidt fix for skge.

Most network drivers request their IRQ when the interface is activated.
sky2 does it in ->probe() instead, because it can work with two-port
cards where the two net_devices use the same IRQ. This works fine most
of the time, except in some situations when the interface gets renamed.
Consider this example:

1. modprobe sky2
   The card is detected as eth0 and requests IRQ 17. Directory
   /proc/irq/17/eth0 is created.
2. There is an udev rule which says this interface should be called
   eth1, so udev renames eth0 -> eth1.
3. modprobe 8139too
   The Realtek card is detected as eth0. It will be using IRQ 17 too.
4. ip link set eth0 up
   Now 8139too requests IRQ 17.

The result is:
WARNING: at fs/proc/generic.c:590 proc_register ...
proc_dir_entry '17/eth0' already registered

The fix is for sky2 to name the irq based on the pci device, as is done
by some other devices DRM, infiniband, ...  ie. sky2@pci:0000:00:00

Subject: net: Use sk_mark for routing lookup in more places

This patch against v2.6.31 adds support for route lookup using sk_mark in some
more places. The benefits from this patch are the following.
First, SO_MARK option now has effect on UDP sockets too.
Second, ip_queue_xmit() and inet_sk_rebuild_header() could fail to do routing
lookup correctly if TCP sockets with SO_MARK were used.

Subject: drm/radeon/kms: Convert RS400/RS480 to new init path & fix legacy VGA
 (V3)

Also cleanup register specific to RS400/RS480. This patch also fix
legacy VGA register used to disable VGA access we were programming
wrong register. Now we should properly disable VGA on r100 up to
rs400 asics. Note that RS400/RS480 resume is broken, it hangs the
computer while reprogramming dynamic clock, doesn't work either
without that patch. We need to spend more time investigating this
issue. Version 2 of the patch remove dead code that was left
commented out in the previous version. Version 3 correct the
placement on IGP of the VRAM inside GPU address space to match the
stollen RAM placement of IGP.

From d4550907157d8b3d5286157c15f1200c44842269 Mon Sep 17 00:00:00 2001
From: Jerome Glisse <jglisse@redhat.com>
Date: Thu, 1 Oct 2009 10:12:06 +0200
Subject: drm/radeon/kms: Convert R100 to new init path (V2)

New init path allow to simply asic initialization and make easier
to trace what happen on each different asic. We are removing most
callback. More cleanup should happen latter to remove even more
callback. Also cleanup register specific to R100,RV200,RV250.
Version 2 correct the placement on IGP of the VRAM inside GPU address
space to match the stollen RAM placement of IGP.

From 3ae91c21dd29e413f4111978152c14061f0984b0 Mon Sep 17 00:00:00 2001
From: Paul Mundt <lethal@linux-sh.org>

Subject: module: fix up CONFIG_KALLSYMS=n build.

Starting from commit 4a4962263f07d14660849ec134ee42b63e95ea9a "reduce
symbol table for loaded modules (v2)", the kernel/module.c build is broken
with CONFIG_KALLSYMS disabled.

  CC      kernel/module.o
kernel/module.c:1995: warning: type defaults to 'int' in declaration of 'Elf_Hdr'
kernel/module.c:1995: error: expected ';', ',' or ')' before '*' token
kernel/module.c: In function 'load_module':
kernel/module.c:2203: error: 'strmap' undeclared (first use in this function)
kernel/module.c:2203: error: (Each undeclared identifier is reported only once
kernel/module.c:2203: error: for each function it appears in.)
kernel/module.c:2239: error: 'symoffs' undeclared (first use in this function)
kernel/module.c:2239: error: implicit declaration of function 'layout_symtab'
kernel/module.c:2240: error: 'stroffs' undeclared (first use in this function)
make[1]: *** [kernel/module.o] Error 1
make: *** [kernel/module.o] Error 2

There are three different issues:

    - layout_symtab() takes a const Elf_Ehdr

    - layout_symtab() needs to return a value

    - symoffs/stroffs/strmap are referenced by the load_module() code
      despite being ifdefed out, which seems unnecessary given the noop
      behaviour of layout_symtab()/add_kallsyms() in the case of
      CONFIG_KALLSYMS=n.

From b3db4a8ad19173a8fd0ced13d47c97910f1ab14b Mon Sep 17 00:00:00 2001
From: Mike Frysinger <vapier@gentoo.org>
Date: Thu, 1 Oct 2009 15:43:56 -0700
Subject: asm-generic/gpio.h: pull in linux/kernel.h for might_sleep()

The asm-generic/gpio.h header uses the might_sleep() macro but doesn't
include the header for it, so any source code that might include
linux/gpio.h before linux/kernel.h can easily lead to a build failure.

Subject: mn10300: fix kernel build failures when using gcc-4.x

Fix some build failures when using gcc-4.x for MN10300.

Firstly, __get_user() fails to build because the pointer points to a const and
__gu_val ends up being read-only:

In file included from include/linux/mempolicy.h:62,
                 from init/main.c:50:
include/linux/pagemap.h: In function 'fault_in_pages_readable':
include/linux/pagemap.h:394: error: read-only variable '__gu_val' used as 'asm' output
include/linux/pagemap.h:394: error: read-only variable '__gu_val' used as 'asm' output
include/linux/pagemap.h:394: error: read-only variable '__gu_val' used as 'asm' output
include/linux/pagemap.h:400: error: read-only variable '__gu_val' used as 'asm' output

include/linux/pagemap.h:400: error: read-only variable '__gu_val' used as 'asm' output
make[1]: *** [init/main.o] Error 1

Secondly, gcc-4 doesn't allow casts of lvalues:

  UPD     include/linux/compile.h
arch/mn10300/kernel/rtc.c: In function 'calibrate_clock':
arch/mn10300/kernel/rtc.c:170: error: lvalue required as left operand of assignment
arch/mn10300/kernel/rtc.c:172: error: lvalue required as left operand of assignment
make[1]: *** [arch/mn10300/kernel/rtc.o] Error 1

These are seen with gcc 4.2.1.

Subject: x86: fix csum_ipv6_magic asm memory clobber

Just like ip_fast_csum, the assembly snippet in csum_ipv6_magic needs a
memory clobber, as it is only passed the address of the buffer, not a
memory reference to the buffer itself.

This caused failures in Hurd's pfinetv4 when we tried to compile it with
gcc-4.3 (bogus checksums).

Subject: sdio: pass whitelisted cis funce tuples to sdio drivers

Some manufacturers provide vendor information in non-vendor specific CIS
tuples.  For example, Broadcom uses an Extended Function tuple to provide
the MAC address on some of their network cards, as in the case of the
Nintendo Wii WLAN daughter card.

This patch allows passing whitelisted FUNCE tuples unknown to the SDIO
core to a matching SDIO driver instead of rejecting them and failing.

Subject: memcg: fix refcnt going negative

__mem_cgroup_largest_soft_limit_node() returns a mem_cgroup_per_zone "mz"
with incremnted mz->mem->css's refcnt.  Then, the caller of this function
has to call css_put(mz->mem->css).

But, mz can be !NULL even if "not found" i.e.  without css_get().  By
this, css->refcnt will go down to minus.

This may cause various things...one of results will be
initite-loop in css_tryget()  as this.

Above shows CPU0 caught in css_tryget()'s inifinite loop because
of bad refcnt.

This is a fix to set mz=NULL at the top of retry path.

__css_put() doesn't check a bug as refcnt goes to minus.
I think it should be caught. This patch adds a check for it.

Subject: memcg: some modification to softlimit under hierarchical memory
 reclaim.

This patch clean up/fixes for memcg's uncharge soft limit path.

Problems:
  Now, res_counter_charge()/uncharge() handles softlimit information at
  charge/uncharge and softlimit-check is done when event counter per memcg
  goes over limit. Now, event counter per memcg is updated only when
  memory usage is over soft limit. Here, considering hierarchical memcg
  management, ancesotors should be taken care of.

  Now, ancerstors(hierarchy) are handled in charge() but not in uncharge().
  This is not good.

  Prolems:
  1. memcg's event counter incremented only when softlimit hits. That's bad.
     It makes event counter hard to be reused for other purpose.

  2. At uncharge, only the lowest level rescounter is handled. This is bug.
     Because ancesotor's event counter is not incremented, children should
     take care of them.

  3. res_counter_uncharge()'s 3rd argument is NULL in most case.
     ops under res_counter->lock should be small. No "if" sentense is better.

Fixes:
  * Removed soft_limit_xx poitner and checks in charge and uncharge.
    Do-check-only-when-necessary scheme works enough well without them.

  * make event-counter of memcg incremented at every charge/uncharge.
    (per-cpu area will be accessed soon anyway)

  * All ancestors are checked at soft-limit-check. This is necessary because
    ancesotor's event counter may never be modified. Then, they should be
    checked at the same time.

Subject: memcg: reduce check for softlimit excess

In charge/uncharge/reclaim path, usage_in_excess is calculated repeatedly
and it takes res_counter's spin_lock every time.

This patch removes unnecessary calls for res_count_soft_limit_excess.

Subject: s3cmci: update probe to use new platform id list

Use the platform id list to match the three different versions of the
hardware block that this driver supports.

This will change the prefix of the console messages produced by this
driver to be prefixed by s3c-mci instead of the hardware block name, such
as s3c2440-mci.

Move to using gpiolib to access the card detect and write protect GPIO
lines instead of using the platform speicifc s3c2410_gpio calls.

Also ensure that the card lines are claimed the same way to avoid overlap
with any other drivers.

Subject: s3cmci: fix direct write to interrupt mask

The clear_imask() call should be used to clear the interrupt mask
register, as it may end up clearing the SDIO interrupt bit if this is
enabled.

Change all writes of zero to SDIIMSK register to use clear_imask() ready
for the SDIO updates.

Subject: s3cmci: add SDIO IRQ support

The controller supports SDIO IRQ detection so add support for hardware
assisted SDIO interrupt detection for the SDIO core.  This improves the
response time for SDIO interrupts and thus the transfer rate from devices
such as the Marvel 8686.

As a note, it does seem that the controller will miss an IRQ than is held
asserted, so there are some manual checks to see if the SDIO interrupt is
active after a transfer.

Major testing on the S3C2440.

Subject: s3cmci: Kconfig selection for PIO/DMA/Both

Add a selection for the data transfer mode of the s3cmci driver, allowing
for either a configuration or rumtime selection of the use of the DMA or
PIO transfer code.

The PIO only mode is 476 bytes smaller than the driver with both methods
compiled in.

Subject: s3cmci: DMA fixes

Fixes for the DMA transfer mode of the driver to try and improve the state
of the code:

- Ensure that dma_complete is set during the end of the command phase
  so that transfers do not stall awaiting the completion

- Update the DMA debugging to provide a bit more useful information
  such as how many DMA descriptors where not processed and print the
  DMA addresses in hexadecimal.

- Fix the DMA channel request code to actually request DMA for the
  S3CMCI block instead of whatever '0' signified.

- Add fallback to PIO if we cannot get the DMA channel, as many of the
  devices with this block only have a limited number of DMA channels.

- Only try and claim and free the DMA channel if we are trying to use it.

This improves the driver DMA code to the point where it can now identify a
card and read the partition table.  However the DMA can still stall when
trying to move data between the host and memory.

Subject: s3cmci: make SDIO IRQ hardware IRQ support build-time configurable

We have found a couple of boards where the SDIO IRQ hardware support has
failed to work properly, and thus we should make it configurable whether
or not to be included in the driver.

Subject: s3cmci: add better support for no card detect or write protect
 available

Add better support for omitting either the card detect or the write
protect GPIOs if the board does not support it.  Add the fields
no_wprotect and no_detect to the platform data which when set indicate the
absence of the respective GPIOs.

Note, this also fixes a minor bug where it tries to free IRQ0 if there is
no detect gpio available.

Subject: cyclades: fix read buffer overflow

irq is declared with size NR_CARDS (4), but the loop containing this
segment runs up until NR_ISA_ADDRS (16), possibly reading from irq[i] (and
trying to use the result)

Identified by the Parfait static scanner.

Subject: serial167: fix read buffer overflow

Check whether index is within bounds before grabbing the element.

Also, since NR_PORTS is defined ARRAY_SIZE(cy_port), cy_port[NR_PORTS] is
out of bounds as well.

Subject: serial: add parameter to force skipping the test for the TXEN bug

Allow users to force skipping the TXEN test at init time. Applies
to all serial ports. Intended for debugging only.

There is a blacklist for devices where we need to skip the test but the
list is not complete.  This lets users force skipping the test so we can
determine if they need to be added to the list.

Some HP machines with weird serial consoles have this problem and there
may be more.

Subject: sscanf(): fix %*s%n

When using %*s, sscanf should honor conversion specifiers immediately
following the %*s.  For example, the following code should find the
position of the end of the string "hello".

  int end;
  char buf[] = "hello    world";
  sscanf(buf, "%*s%n", &end);
  printf("%d\n", end);

Ideally, sscanf would advance the fmt and str pointers the same as it
would without the *, but the code for that is rather complicated and is
not included in the patch.

spi_imx_setup() is only called by spi_setup().  The latter does the
initialization already.

Otherwise the config function uses random data from the stack.  This
didn't stick out because config is called once more in the chipselect
function with correct parameters.

spi_imx_chipselect() made things that should be (and mostly are) done by
spi_imx_setupxfer.  Only setting the tx and rx functions was missing.

Subject: drm/radeon/kms: Convert RS600 to new init path

New init path allow to simply asic initialization and make easier
to trace what happen on each different asic. We are removing most
callback. Do a massive RS600 register cleanup to clarify RS600
register, we are still bit fuzy on some register and waiting for
more informations. I don't have hw to test, so this patch is a
best effort to not break anythings and to try to improve things.

From 62a8ea3f7bb61e5f92db0a648b7cc566852c36ec Mon Sep 17 00:00:00 2001
From: Jerome Glisse <jglisse@redhat.com>
Date: Thu, 1 Oct 2009 18:02:11 +0200
Subject: drm/radeon/kms: Remove old init path as no hw use it anymore

This remove old init path and allow code cleanup, now all hw
use the new init path, see top of radeon.h for description of
this.

From 81cc35bfc19ebe4b823396fe4fef67a923360916 Mon Sep 17 00:00:00 2001
From: Jerome Glisse <jglisse@redhat.com>
Date: Thu, 1 Oct 2009 18:02:12 +0200
Subject: drm/radeon/kms: Fix R600 write back buffer

This split write back buffer handling into 3 functions,
wb_fini for cleanup, wb_enable/wb_disable for enabling/disabling
write back used for suspend/resume. This should fix
potential issue of letting the write back active before
suspending. We need to allocate memory in wb_enable because
we can only allocate once GART is running.

From a3c1945aaf48a5893238d95139f202531994094d Mon Sep 17 00:00:00 2001
From: Jerome Glisse <jglisse@redhat.com>
Date: Thu, 1 Oct 2009 18:02:13 +0200
Subject: drm/radeon/kms: Fix R600/RV770 startup path & reset

We were calling reset unconditionaly in the startup path
this is bad we need to call GPU reset for a good reason
as after reset the GPU is in unknown states. To avoid any
more bad things to happen we now also unconditionaly
reinitialize the GPU after reset. This patch fix few issues
reported by different people regarding KMS & R6XX/RV7XX hw.

Subject: drm/radeon/kms: Fix R600/RV770 disable acceleration path

When acceleration doesn't work we should free associated memory
and stop GPU block responsible for hardware acceleration so we
don't waste resource or let think one component of the driver that
a GPU feature is working/running while it doesn't actualy work.

It was checked with 'speaker-test -c 8 -s 3' and (un)mute surround or

Subject: ALSA: hda - Fix / improve ALC66x parser

The auto-parser for ALC662/663/272 codecs doesn't work properly when
a speaker is connected to mono NID 0x17, and doesn't handle the dynamic
DAC assignment properly.

This patch fixes the issues and also improves the assignment of DACs
so that HP and speakers can have independent volume controls.

Subject: ASoC: Fix SND_SOC_DAPM_LINE handling

Since the SND_SOC_DAPM_LINE can be input or output, additional check is
needed in order to determine if the widget is connected as input or
output.
When checking for connected outputs, if the widget is line, than check
if the sources list is not empty (line is connected as output)
For input endpoint check, when the widget is line, also check if the
sinks list is not empty (line is connected as input).

Subject: ALSA: usb - Use strlcat() correctly

Don't pass the advanced position to strlcat() but just gives the buffer
head position so that the max size limit can be checked correctly.
Introduced a new helper function to standaralize strlcat() calls.

Subject: x86: EDAC: MCE: Fix MCE decoding callback logic

Make decoding of MCEs happen only on AMD hardware by registering a
non-default callback only on CPU families which support it.

While looking at the interaction of decode_mce() with the other MCE
code i also noticed a few other things and made the following
cleanups/fixes:

 - Fixed the mce_decode() weak alias - a weak alias is really not
   good here, it should be a proper callback. A weak alias will be
   overriden if a piece of code is built into the kernel - not
   good, obviously.

 - The patch initializes the callback on AMD family 10h and 11h.

 - Added the more correct fallback printk of:

	No support for human readable MCE decoding on this CPU type.
	Transcribe the message and run it through 'mcelog --ascii' to decode.

   On CPUs that dont have a decoder.

 - Made the surrounding code more readable.

Note that the callback allows us to have a default fallback -
without having to check the CPU versions during the printout
itself. When an EDAC module registers itself, it can install the
decode-print function.

(there's no unregister needed as this is core code.)

version -v2 by Borislav Petkov:

 - add K8 to the set of supported CPUs

 - always build in edac_mce_amd since we use an early_initcall now

 - fix checkpatch warnings

Subject: x86: EDAC: carve out AMD MCE decoding logic

This converts the MCE decoding logic into a standalone config
option which can be built-in or a module, the first one being the
default for MCEs happening early on in the boot process.

This, beyond being separated in a cleaner way, also saves RAM by
making the decoding logic modular.

Subject: [SCSI] scsi_dh_rdac: Fix for returning correct mode select cmd return
 info

The function mode_select_handle_sense returns SCSI_DH_OK even when there is a sense code which is incorrect. Removing it so that it returns SCSI_DH_IO when there is sense that is not handled by this function.

Subject: [SCSI] hptiop: Add RR44xx adapter support

Most code changes were made to support RR44xx adapters.
- add more PCI device ID.
- using PCI BAR[2] to access RR44xx IOP.
- using PCI BAR[0] to check and clear RR44xx IRQ.

Subject: [SCSI] bnx2i: Fix context mapping issue for architectures with
 PAGE_SIZE != 4096

5706/5708/5709 devices allow driver/user to set page size. By default it is
set to 4096.  Current drivers do not program this register based on
architecture type (e.g. x86 = 4K, IA64 = 16K) and by choice lets device use
the defaults. So while mapping connection context memory (doorebll registers),
driver has to match page size used by the device. Included change fixes the
issue we uncovered during IA64 testing

Subject: [SCSI] sr: consider the last written sector when determining media
 size

On certain cases, UDF disc doesn't report capacity correctly via
READ_CAPACITY but TOC or trackinfo contains valid information which
can be obtained using cdrom_get_last_written().  ide-cd considers both
values and uses the larger one.  Do the same in sr.  This fixes
bko#9668.

Subject: [SCSI] sg: Free data buffers after calling blk_rq_unmap_user

Running sg_luns on s390x with CONFIG_DEBUG_PAGEALLOC enabled fails
with EFAULT from the SG_IO ioctl. The EFAULT is the result from
copy_to_user failing in this call chain:

sg_ioctl
sg_new_read
sg_finish_rem_req
blk_rq_unmap_user
__blk_rq_unmap_user
bio_uncopy_user
__bio_copy_iov
copy_to_user

The sg driver calls sg_remove_scat to free the memory pages before
calling blk_rq_unmap_user that tries to copy the data back to
userspace. Change the order to first call blk_rq_unmap_user before
freeing the pages in sg_remove_scat.

Subject: [SCSI] Retry ADD_TO_MLQUEUE return value for EH commands

A target reset when I/O is ongoing might result
an eventual device offline, as scsi_eh_completed_normally()
might return ADD_TO_MLQUEUE in addition to the
advertised SUCCESS, FAILED, and NEEDS_RETRY.

Which is unfortunate as scsi_send_eh_cmnd() will
therefore map ADD_TO_MLQUEUE to FAILED instead of
the more appropriate NEEDS_RETRY.

Subject: [SCSI] Deprecate SCSI_PROT_*_CONVERT operations

The checksum format is orthogonal to whether the protection information
is being passed on beyond the HBA or not.  It is perfectly valid to use
a non-T10 CRC with WRITE_STRIP and READ_INSERT.

Consequently it no longer makes sense to explicitly refer to the
conversion in the protection operation.  Update sd_dif and lpfc
accordingly.

So far we have only issued DIF commands if CONFIG_BLK_DEV_INTEGRITY is
enabled.  However, communication between initiator and target should be
independent of protection information DMA.  There are DIF-only host
adapters coming out that will be able to take advantage of this.

Move the relevant DIF bits to sd.c.

Subject: [SCSI] sd: Support disks formatted with DIF Type 2

Disks formatted with DIF Type 2 reject READ/WRITE 6/10/12/16 commands
when protection is enabled.  Only the 32-byte variants are supported.

Implement support for issusing 32-byte READ/WRITE and enable Type 2
drives in the protection type detection logic.

Subject: [SCSI] scsi_debug: Implement support for DIF Type 2

Add support for 32-byte READ/WRITE as well as DIF Type 2 protection.

Reject protected 10/12/16 byte READ/WRITE commands when Type 2 is
enabled.

Verify Type 2 reference tag according to Expected Initial LBA in 32-byte
CDB.

From 595bb0bd62edb28a965993d90e0fa1285560ce53 Mon Sep 17 00:00:00 2001
From: "Kashyap, Desai" <kashyap.desai@lsi.com>
Date: Mon, 14 Sep 2009 11:02:48 +0530
Subject: [SCSI] mpt2sas: Added SCSIIO, Internal and high priority memory pools
 to support multiple TM

1) create a pool of high priority message frames in the region of memory
between message frames and chains.  The modifications are in
_base_allocate_memory_pools.  Also create a seperate pool of memory for
internal commands located near the same region of memory.  The pool of high
priority message frames is restriced by the facts->HighPriorityCredit.

2) Create additional API for accessing request message frames. New function
mpt2sas_base_get_smid_hpr is for highpriority request. New function
mpt2sas_base_get_smid_scsiio for SCSI_IO, passing in the scsi command
pointer.  The mpt2sas_base_get_smid function is for requesting internal
commands.

3) Added new function _base_get_cb_idx to obtain the callback
index from one of the three pools of request message frames.

4) Removed wrapper functions _scsih_scsi_lookup_set and
_scsih_scsi_lookup_getclear. These were removed because this handling was
moved into mpt2sas_base_get_smid_scsiio and mpt2sas_base_free_smid.

5) The function mpt2sas_base_free_smid is modified so the request message
frames are put back on one of the three pools of request message frames.

From 77e63ed44305e89c0564f8292f9cd5764d4fddfb Mon Sep 17 00:00:00 2001
From: "Kashyap, Desai" <kashyap.desai@lsi.com>
Date: Mon, 14 Sep 2009 11:04:23 +0530
Subject: [SCSI] mpt2sas: Target Reset will be issued from Interrupt context.

(1) Added three new functions to handle sending target resest and OP_REMOVE
from interrupt time, they are _scsih_tm_tr_send, _scsih_tm_tr_complete, and
_scsih_sas_control_complete.  This code will create a link list of pending
target resets if there is no more available request in the hipriority
request queue.  The list is stored in ioc->delayed_tr_list.

(2) All callback handler return type is changed from void to u8.
Now _base_interrupt will check for return type of callback handlers to
take decision of message frame is already freed or not.
In genral,
Return 1 meaning mf should be freed from _base_interrupt
       0 means the mf is freed from function.

Subject: [SCSI] mpt2sas: Call init_completion on a per request basis.

Now driver call init_completion on a per request basis.  At some
point the wait_for_completion_timeout is not waiting for the timeout,
instead returning immediately, thus going into diag reset.  This fix will
address all request using the wait_for_completion_timeout API. The previous
implimentation was only calling init_completion at driver
load time.

Subject: [SCSI] mpt2sas: Timeout occurred within the HANDSHAKE logic while
 waiting on firmware to ACK.

Following a diag_reset, a request to send an ioc_init is timing out.  The
timeout occurred within the HANDSHAKE logic while waiting on firmware to
acknowledge that the driver had wrote to the doorbell register.  This was
root caused to a logic timeout in the firmware code.  The proposed solution
is for the driver to call the udelay instead of msleep API in function where
its looping reading the interrupt status.  In addition to this change, there
were two additional cases where we deleted the clearing interrupt status
outside handshake context.

Subject: [SCSI] zfcp: Fix initial device and cfdc for delayed adapter
 allocation

With the change for delaying the allocation of zfcp_adapter, the
initial device parameter function has to first call
ccw_device_set_online which allocates the zfcp_adapter structure.
Change this and adapt the cfdc part accordingly.

Subject: [SCSI] zfcp: Fix oops during shutdown of offline device

With the change that the zfcp_adapter struct is only allocated when
the device is set online, the shutdown handler has to check for a
non-existing zfcp_adapter struct. On the other hand, this check is not
necessary in the offline callback, since an online device has the
zfcp_adapter allocated and we go through the offline callback before
removing the ccw device.

cancel_work_sync is called while holding the config_mutex. But the
work that is being cancelled or flushed also uses the config_mutex.
Fix the resulting deadlock possibility by calling cancel_work_sync
earlier without holding the mutex. The best place to do is is after
offlining the device.  No new port scan work will be scheduled for the
offline device, so this is a safe place to call cancel_work_sync.

The problem is that the chchp --vary 0 leads to zfcp first calling
fc_remote_port_delete which blocks all scsi devices on the remote
port. Calling scsi_remove_device later lets the sd driver issue a
SYNCHRONIZE_CACHE command. This command stays on the "stopped" request
requeue because the SCSI device is blocked. Fix this by first removing
the scsi and fc hosts which removes all scsi devices and do not use
scsi_remove_device.

Free an acpi_get_object_info() buffer when we're finished.  Skip the
acpi_get_name() altogether -- it was only used for a printk that was
really just for debug anyway.

Subject: net: splice() from tcp to pipe should take into account O_NONBLOCK

tcp_splice_read() doesnt take into account socket's O_NONBLOCK flag

Before this patch :

splice(socket,0,pipe,0,128*1024,SPLICE_F_MOVE);
causes a random endless block (if pipe is full) and
splice(socket,0,pipe,0,128*1024,SPLICE_F_MOVE | SPLICE_F_NONBLOCK);
will return 0 immediately if the TCP buffer is empty.

User application has no way to instruct splice() that socket should be in blocking mode
but pipe in nonblock more.

Many projects cannot use splice(tcp -> pipe) because of this flaw.

http://git.samba.org/?p=samba.git;a=history;f=source3/lib/recvfile.c;h=ea0159642137390a0f7e57a123684e6e63e47581;hb=HEAD
http://lkml.indiana.edu/hypermail/linux/kernel/0807.2/0687.html

Linus introduced  SPLICE_F_NONBLOCK in commit 29e350944fdc2dfca102500790d8ad6d6ff4f69d
(splice: add SPLICE_F_NONBLOCK flag )

  It doesn't make the splice itself necessarily nonblocking (because the
  actual file descriptors that are spliced from/to may block unless they
  have the O_NONBLOCK flag set), but it makes the splice pipe operations
  nonblocking.

Linus intention was clear : let SPLICE_F_NONBLOCK control the splice pipe mode only

This patch instruct tcp_splice_read() to use the underlying file O_NONBLOCK
flag, as other socket operations do.

Users will then call :

splice(socket,0,pipe,0,128*1024,SPLICE_F_MOVE | SPLICE_F_NONBLOCK );

to block on data coming from socket (if file is in blocking mode),
and not block on pipe output (to avoid deadlock)

First version of this patch was submitted by Octavian Purdila

Subject: e1000e/igb/ixgbe: Don't report an error if devices don't support AER

The only error returned by pci_{en,dis}able_pcie_error_reporting() is
-EIO which simply means that Advanced Error Reporting is not supported.
There is no need to report that, so remove the error check from e1000e,
igb and ixgbe.

Subject: x86: Simplify bound checks in the MTRR code

The current bound checks for copy_from_user in the MTRR driver are
not as obvious as they could be, and gcc agrees with that.

This patch simplifies the boundary checks to the point that gcc can
now prove to itself that the copy_from_user() is never going past
its bounds.

Subject: cnic: Fix NETDEV_UP event processing.

This fixes the problem of not handling the NETDEV_UP event properly
during hot-plug or modprobe of bnx2 after cnic.  The handling was
skipped by mistakenly using "else if" to check for the event.

Also update version to 2.0.1.

Subject: cfq-iosched: add a knob for desktop interactiveness

This is basically identical to what Vivek Goyal posted, but combined
into one and labelled 'desktop' instead of 'fairness'. The goal
is to continue to improve on the latency side of things as it relates
to interactiveness, keeping the questionable bits under this sysfs
tunable so it would be easy for throughput-only people to turn off.

Apart from adding the interactive sysfs knob, it also adds the
behavioural change of allowing slice idling even if the hardware
does tagged command queuing.

Subject: [SCSI] be2iscsi: Moving to pci_pools v3

This patch contains changes to use pci_pools for iscsi hdr
instead of pci_alloc_consistent. Here we alloc and free to pool
for every IO

v3:
- Remove cleanup loop in beiscsi_session_destroy
- Fixup for allocation failure handling in beiscsi_alloc_pdu
- Removed unused variable in beiscsi_session_destroy.

Subject: [SCSI] st: fix possible memory use after free after MTSETBLK ioctl

A memory use after free bug can manifest if the MTSETBLK or SET_DENS_AND_BLK
ioctl features are used to set the tape's blocksize from 0 to non-zero.
After the driver sets the new block size, in this one case it calls
normalize_buffer() to free the device's internal data buffers.  However, the
ioctl code assumes there is always a buffer and does not check or allocate
a buffer if there isn't one.  So any following ioctl calls can corrupt
a part of memory by writing data to memory that the st driver had freed.

This patch removes the normalize_buffer() call and the specialness of
changing from a 0 to non-zero blocksize to fix the possible use of
memory after it has been freed by the st driver.

As of 559ee21d261a54c42594ef9405d27e9008eedf44 the actual refresh rate
is returned by the function of drm_mode_vrefresh, so multiply the refresh
rate by 1000 in TV mode validation.

At the same time the error is expanded from 10 to 1000.

Subject: [SCSI] qla2xxx: Fix NULL ptr deref bug in fail path during queue
 create

Current code attempts to clean up resources when queue create fails and there it
invokes queue free call with a (NULL) pointer to the queue which could not be
allocated in the first place. Fix it by returning directly without invoking the
queue free call as no resources has been allocated at that point of time.

Subject: ARM: 5739/1: ARM: allow empty ATAG_CORE

From: David Brown <davidb@quicinc.com>

The ATAG_CORE is allowed to be empty.  Although this is handled
by parse_tag_core(), __vet_atags during startup rejects this tag
unless it contains data.  Allow the initial tag to be either the
full size, or empty.

Subject: ARM: 5740/1: fix valid_phys_addr_range() range check

Commit 1522ac3ec95ff0230e7aa516f86b674fdf72866c
("Fix virtual to physical translation macro corner cases")
breaks the end of memory check in valid_phys_addr_range().
The modified expression results in the apparent /dev/mem size
being 2 bytes smaller than what it actually is.

This patch reworks the expression to correctly check the address,
while maintaining use of a valid address to __pa().

Subject: ARM: 5727/1: Pass IFSR register to do_PrefetchAbort()

Instruction fault status register, IFSR, was introduced on ARMv6 to
provide status information about the last insturction fault. It
needed for proper prefetch abort handling.

Now we have three prefetch abort model:

  * legacy - for CPUs before ARMv6. They doesn't provide neither
    IFSR nor IFAR. We simulate IFSR with section translation fault
    status for them to generalize code;
  * ARMv6 - provides IFSR, but not IFAR;
  * ARMv7 - provides both IFSR and IFAR.

Subject: ARM: 5728/1: Proper prefetch abort handling on ARMv6 and ARMv7

Currently, on ARMv6 and ARMv7, if an application tries to execute
code (or garbage) on non-executable page it hangs. It caused by
incorrect prefetch abort handling. Now every prefetch abort
processes as a translation fault.

To fix this we have to analyze instruction fault status register
to figure out reason why we've got the abort and process it
accordingly.

To make IFSR different from DFSR we set bit 31 which is reserved in
both IFSR and DFSR.

This patch also tries to protect from future hangs on unexpected
exceptions. An application will be killed if unexpected exception
type was received.

This fixes the following warning:

fs/ext4/inode.c: In function 'ext4_dirty_inode':
fs/ext4/inode.c:5615: warning: unused variable 'current_handle'

We remove the jbd_debug() statement which does use current_handle, as
it's not terribly important in the grand scheme of things.

Thanks to Stephen Rothwell for pointing this out.

Subject: [PATCH] ext4: retry failed direct IO allocations

On a 256M filesystem, doing this in a loop:

        xfs_io -F -f -d -c 'pwrite 0 64m' test
        rm -f test

eventually leads to ENOSPC.  (the xfs_io command does a
64m direct IO write to the file "test")

As with other block allocation callers, it looks like we need to
potentially retry the allocations on the initial ENOSPC.

Subject: ACPI: Fix bound checks for copy_from_user in the acpi /proc code

The ACPI /proc write() code takes an unsigned length argument like any write()
function, but then assigned it to a *signed* integer called "len".
Only after this is a sanity check for len done to make it not larger than 4.

Due to the type change a len < 0 is in principle also possible; this patch
adds a check for this.

Subject: SFI: fix section mismatch warnings in sfi_core.c

The function sfi_map_memory/sfi_unmap_memory uses
early_ioremap/early_iounmap respectively, which refers to a __init
function.  And function sfi_check_table also refers to a __init function
sfi_verify_table.  Since the references are valid, so use __ref to get rid
of the warnings.

 We were warned by the following warnings:

  LD      vmlinux.o
  MODPOST vmlinux.o
WARNING: vmlinux.o(.text+0xb6ba3a): Section mismatch in reference from
the function sfi_map_memory() to the function
.init.text:early_ioremap()
The function sfi_map_memory() references
the function __init early_ioremap().
This is often because sfi_map_memory lacks a __init
annotation or the annotation of early_ioremap is wrong.

the function sfi_unmap_memory() to the function
.init.text:early_iounmap()
The function sfi_unmap_memory() references

Subject: ACPI: kill overly verbose "throttling states" log messages

I was recently lucky enough to get a 64-CPU system.  The processors
actually have T-states, so my kernel log ends up with 64 lines like:

    ACPI: Processor [CPU0] (supports xx throttling states)

This is pretty useless clutter because

 - this info is already available after boot from
   /proc/acpi/processor/CPUnn/throttling

 - there's also an ACPI_DEBUG_PRINT() in processor_throttling.c that
   gives the same info on boot for anyone who *really* cares.

So just delete the code that prints the throttling states in
processor_core.c.

continue do an early scan for all machines, but this Compal model.

Subject: cfq-iosched: delay async IO dispatch, if sync IO was just done

o Do not allow more than max_dispatch requests from an async queue, if some
  sync request has finished recently. This is in the hope that sync activity
  is still going on in the system and we might receive a sync request soon.
  Most likely from a sync queue which finished a request and we did not enable
  idling on it.

Subject: cfq-iosched: rename 'desktop' sysfs entry to 'low_latency'

Don't think that's necessarily a perfect description of what this
option fiddles with, but it's probably better than 'desktop'.

Subject: HWPOISON: Clean up PR_MCE_KILL interface

While writing the manpage I noticed some shortcomings in the
current interface.

- Define symbolic names for all the different values
- Boundary check the kill mode values
- For symmetry add a get interface too. This allows library
code to get/set the current state.
- For consistency define a PR_MCE_KILL_DEFAULT value

+What is hwpoison?
+
+Upcoming Intel CPUs have support for recovering from some memory errors
+(``MCA recovery''). This requires the OS to declare a page "poisoned",
+kill the processes associated with it and avoid using it in the future.
+
+This patchkit implements the necessary infrastructure in the VM.
+
+To quote the overview comment:
+
+ * High level machine check handler. Handles pages reported by the
+ * hardware as being corrupted usually due to a 2bit ECC memory or cache
+ * failure.
+ *
+ * This focusses on pages detected as corrupted in the background.
+ * When the current CPU tries to consume corruption the currently
+ * running process can just be killed directly instead. This implies
+ * that if the error cannot be handled for some reason it's safe to
+ * just ignore it because no corruption has been consumed yet. Instead
+ * when that happens another machine check will happen.
+ *
+ * Handles page cache pages in various states. The tricky part
+ * here is that we can access any page asynchronous to other VM
+ * users, because memory failures could happen anytime and anywhere,
+ * possibly violating some of their assumptions. This is why this code
+ * has to be extremely careful. Generally it tries to use normal locking
+ * rules, as in get the standard locks, even if that means the
+ * error handling takes potentially a long time.
+ *
+ * Some of the operations here are somewhat inefficient and have non
+ * linear algorithmic complexity, because the data structures have not
+ * been optimized for this case. This is in particular the case
+ * for the mapping from a vma to a process. Since this case is expected
+ * to be rare we hope we can get away with this.
+
+The code consists of a the high level handler in mm/memory-failure.c,
+a new page poison bit and various checks in the VM to handle poisoned
+pages.
+
+The main target right now is KVM guests, but it works for all kinds
+of applications. KVM support requires a recent qemu-kvm release.
+
+For the KVM use there was need for a new signal type so that
+KVM can inject the machine check into the guest with the proper
+address. This in theory allows other applications to handle
+memory failures too. The expection is that near all applications
+won't do that, but some very specialized ones might.
+
+---
+
+There are two (actually three) modi memory failure recovery can be in:
+
+vm.memory_failure_recovery sysctl set to zero:
+	All memory failures cause a panic. Do not attempt recovery.
+	(on x86 this can be also affected by the tolerant level of the
+	MCE subsystem)
+
+early kill
+	(can be controlled globally and per process)
+	Send SIGBUS to the application as soon as the error is detected
+	This allows applications who can process memory errors in a gentle
+	way (e.g. drop affected object)
+	This is the mode used by KVM qemu.
+
+late kill
+	Send SIGBUS when the application runs into the corrupted page.
+	This is best for memory error unaware applications and default
+	Note some pages are always handled as late kill.
+
+---
+
+User control:
+
+vm.memory_failure_recovery
+	See sysctl.txt
+
+vm.memory_failure_early_kill
+	Enable early kill mode globally
+
+PR_MCE_KILL
+	Set early/late kill mode/revert to system default
+	arg1: PR_MCE_KILL_CLEAR: Revert to system default
+	arg1: PR_MCE_KILL_SET: arg2 defines thread specific mode
+		PR_MCE_KILL_EARLY: Early kill
+		PR_MCE_KILL_LATE:  Late kill
+		PR_MCE_KILL_DEFAULT: Use system global default
+PR_MCE_KILL_GET
+	return current mode
+
+

+
+Testing:
+
+madvise(MADV_POISON, ....)
+	(as root)

Subject: m32r: Fix IPI function calls for SMP

This patch fixes the m32r SMP kernel after 2.6.27.

A part of the following patch breaks m32r SMP operation.
> m32r: convert to generic helpers for IPI function calls
> commit 7b7426c8a615cf61df9a77b9df7d5b75d91e3fa0

In the above patch, a CALL_FUNC_SINGLE_IPI was newly introduced,
but the its IPI vector number was wrong in the patch code.

The m32r SMP kernel hanged-up during boot operation, because
the CPU_BOOT_IPI was called instead of CALL_FUNC_SINGLE_IPI
(CPU_BOOT_IPI had no side effect at that time because the 2nd
core had already been started up),
as a result, csd_unlock() was not called, then a dead lock
occurred in csd_lock_wait() after the detection of Compact Flash
memory as IDE generic disk.

Subject: tty: Avoid dropping ldisc_mutex over hangup tty re-initialization

A couple of people have hit the WARN_ON() in drivers/char/tty_io.c,
tty_open() that is unhappy about seeing the tty line discipline go away
during the tty hangup. See for example

	http://bugzilla.kernel.org/show_bug.cgi?id=14255

and the reason is that we do the tty_ldisc_halt() outside the
ldisc_mutex in order to be able to flush the scheduled work without a
deadlock with vhangup_work.

However, it turns out that we can solve this particular case by

 - using "cancel_delayed_work_sync()" in tty_ldisc_halt(), which waits
   for just the particular work, rather than synchronizing with any
   random outstanding pending work.

   This won't deadlock, since the buf.work we synchronize with doesn't
   care about the ldisc_mutex, it just flushes the tty ldisc buffers.

 - realize that for this particular case, we don't need to wait for any
   hangup work, because we are inside the hangup codepaths ourselves.

so as a result we can just drop the flush_scheduled_work() entirely, and
then move the tty_ldisc_halt() call to inside the mutex.  That way we
never expose the partially torn down ldisc state to tty_open(), and hold
the ldisc_mutex over the whole sequence.

When svm_vcpu_load is called while the vcpu is running in
guest mode the tsc adjustment made there is lost on the next
emulated #vmexit. This causes the tsc running backwards in
the guest. This patch fixes the issue by also adjusting the
tsc_offset in the emulated hsave area so that it will not
get lost.

Set KVM_REQ_TLB_FLUSH in vmx_vcpu_load, when switching pcpus, which
will invalidate both VPID and EPT mappings on the next vm-entry.

Subject: KVM: Prevent overflow in KVM_GET_SUPPORTED_CPUID

The number of entries is multiplied by the entry size, which can
overflow on 32-bit hosts.  Bound the entry count instead.

Subject: KVM: MMU: dont hold pagecount reference for mapped sptes pages

When using mmu notifiers, we are allowed to remove the page count
reference tooken by get_user_pages to a specific page that is mapped
inside the shadow page tables.

This is needed so we can balance the pagecount against mapcount
checking.

(Right now kvm increase the pagecount and does not increase the
mapcount when mapping page into shadow page table entry,
so when comparing pagecount against mapcount, you have no
reliable result.)

while filling memory.

From 0f78ab9899e9d6acb09d5465def618704255963b Mon Sep 17 00:00:00 2001
From: Jens Axboe <jens.axboe@oracle.com>

Subject: Revert "Seperate read and write statistics of in_flight requests"

This reverts commit a9327cac440be4d8333bba975cbbf76045096275.

Corrado Zoccolo <czoccolo@gmail.com> reports:

"with 2.6.32-rc1 I started getting the following strange output from

Global values for service time and utilization are garbage. For
interval values, utilization is always 100%, and service time is
higher than normal.

I bisected it down to:
[a9327cac440be4d8333bba975cbbf76045096275] Seperate read and write
statistics of in_flight requests
and verified that reverting just that commit indeed solves the issue
on 2.6.32-rc1."

So until this is debugged, revert the bad commit.

Subject: i2c: Move misc devices documentation

Some times ago the eeprom and max6875 drivers moved to
drivers/misc/eeprom, but their documentation did not follow. It's
finally time to get rid of Documentation/i2c/chips.

-Description
------------
-
-This is a simple EEPROM module meant to enable reading the first 256 bytes
-of an EEPROM (on a SDRAM DIMM for example). However, it will access serial
-EEPROMs on any I2C adapter. The supported devices are generically called
-24Cxx, and are listed above; however the numbering for these
-industry-standard devices may vary by manufacturer.
-
-This module was a programming exercise to get used to the new project
-organization laid out by Frodo, but it should be at least completely
-effective for decoding the contents of EEPROMs on DIMMs.
-
-DIMMS will typically contain a 24C01A or 24C02, or the 34C02 variants.
-The other devices will not be found on a DIMM because they respond to more
-than one address.
-
-DDC Monitors may contain any device. Often a 24C01, which responds to all 8
-addresses, is found.
-
-Recent Sony Vaio laptops have an EEPROM at 0x57. We couldn't get the
-specification, so it is guess work and far from being complete.
-
-The Microchip 24AA52/24LCS52, ST M34C02, and others support an additional
-software write protect register at 0x30 - 0x37 (0x20 less than the memory
-location). The chip responds to "write quick" detection at this address but
-does not respond to byte reads. If this register is present, the lower 128
-bytes of the memory array are not write protected. Any byte data write to

-Description
------------
-
-The Maxim MAX6875 is an EEPROM-programmable power-supply sequencer/supervisor.
-It provides timed outputs that can be used as a watchdog, if properly wired.
-It also provides 512 bytes of user EEPROM.
-
-At reset, the MAX6875 reads the configuration EEPROM into its configuration
-registers.  The chip then begins to operate according to the values in the
-registers.
-
-The Maxim MAX6874 is a similar, mostly compatible device, with more intputs
-and outputs:
-             vin     gpi    vout
-MAX6874        6       4       8
-MAX6875        4       3       5
-
-See the datasheet for more information.

-
-Sysfs entries
--------------
-
-eeprom        - 512 bytes of user-defined EEPROM space.
-
-
-General Remarks
----------------
-
-Valid addresses for the MAX6875 are 0x50 and 0x52.
-Valid addresses for the MAX6874 are 0x50, 0x52, 0x54 and 0x56.
-The driver does not probe any address, so you must force the address.
-
-Example:
-$ modprobe max6875 force=0,0x50
-
-The MAX6874/MAX6875 ignores address bit 0, so this driver attaches to multiple
-addresses.  For example, for address 0x50, it also reserves 0x51.
-The even-address instance is called 'max6875', the odd one is 'dummy'.
-
-
-Programming the chip using i2c-dev
-----------------------------------
-
-Use the i2c-dev interface to access and program the chips.
-Reads and writes are performed differently depending on the address range.
-
-The configuration registers are at addresses 0x00 - 0x45.
-Use i2c_smbus_write_byte_data() to write a register and
-i2c_smbus_read_byte_data() to read a register.
-The command is the register number.
-
-Examples:
-To write a 1 to register 0x45:
-  i2c_smbus_write_byte_data(fd, 0x45, 1);
-
-To read register 0x45:
-  value = i2c_smbus_read_byte_data(fd, 0x45);
-
-
-The configuration EEPROM is at addresses 0x8000 - 0x8045.
-The user EEPROM is at addresses 0x8100 - 0x82ff.
-
-Use i2c_smbus_write_word_data() to write a byte to EEPROM.
-
-The command is the upper byte of the address: 0x80, 0x81, or 0x82.
-The data word is the lower part of the address or'd with data << 8.
-  cmd = address >> 8;
-  val = (address & 0xff) | (data << 8);
-
-Example:
-To write 0x5a to address 0x8003:
-  i2c_smbus_write_word_data(fd, 0x80, 0x5a03);
-
-
-Reading data from the EEPROM is a little more complicated.
-Use i2c_smbus_write_byte_data() to set the read address and then
-i2c_smbus_read_byte() or i2c_smbus_read_i2c_block_data() to read the data.
-
-Example:
-To read data starting at offset 0x8100, first set the address:
-  i2c_smbus_write_byte_data(fd, 0x81, 0x00);
-
-And then read the data
-  value = i2c_smbus_read_byte(fd);
-
-  or
-
-  count = i2c_smbus_read_i2c_block_data(fd, 0x84, 16, buffer);
-
-The block read should read 16 bytes.
-0x84 is the block read command.
-
-See the datasheet for more details.

+Description
+-----------
+
+This is a simple EEPROM module meant to enable reading the first 256 bytes
+of an EEPROM (on a SDRAM DIMM for example). However, it will access serial
+EEPROMs on any I2C adapter. The supported devices are generically called
+24Cxx, and are listed above; however the numbering for these
+industry-standard devices may vary by manufacturer.
+
+This module was a programming exercise to get used to the new project
+organization laid out by Frodo, but it should be at least completely
+effective for decoding the contents of EEPROMs on DIMMs.
+
+DIMMS will typically contain a 24C01A or 24C02, or the 34C02 variants.
+The other devices will not be found on a DIMM because they respond to more
+than one address.
+
+DDC Monitors may contain any device. Often a 24C01, which responds to all 8
+addresses, is found.
+
+Recent Sony Vaio laptops have an EEPROM at 0x57. We couldn't get the
+specification, so it is guess work and far from being complete.
+
+The Microchip 24AA52/24LCS52, ST M34C02, and others support an additional
+software write protect register at 0x30 - 0x37 (0x20 less than the memory
+location). The chip responds to "write quick" detection at this address but
+does not respond to byte reads. If this register is present, the lower 128
+bytes of the memory array are not write protected. Any byte data write to
+this address will write protect the memory array permanently, and the
+device will no longer respond at the 0x30-37 address. The eeprom driver
+does not support this register.
+
+Lacking functionality:
+
+* Full support for larger devices (24C04, 24C08, 24C16). These are not
+typically found on a PC. These devices will appear as separate devices at
+multiple addresses.
+
+* Support for really large devices (24C32, 24C64, 24C128, 24C256, 24C512).
+These devices require two-byte address fields and are not supported.
+
+* Enable Writing. Again, no technical reason why not, but making it easy
+to change the contents of the EEPROMs (on DIMMs anyway) also makes it easy
+to disable the DIMMs (potentially preventing the computer from booting)
+until the values are restored somehow.
+
+Use:

Subject: max6875: Discard obsolete detect method

There is no point in implementing a detect callback for the MAX6875, as
this device can't be detected. It was there solely to handle "force"
module parameters to instantiate devices, but now we have a better sysfs
interface that can do the same.

So we can get rid of the ugly module parameters and the detect callback.
This basically divides the binary module size by 2.

Subject: ltc4215/ltc4245: Discard obsolete detect methods

There is no point in implementing a detect callback for the LTC4215
and LTC4245, as these devices can't be detected. It was there solely
to handle "force" module parameters to instantiate devices, but now
we have a better sysfs interface that can do the same.

So we can get rid of the ugly module parameters and the detect
callbacks. This shrinks the binary module sizes by 36% and 46%,
respectively.

Subject: i2c: Hide probe errors caused by ACPI resource conflicts

When an ACPI resource conflict is detected, error messages are already
printed by ACPI. There's no point in causing the driver core to print
more error messages, so return one of the error codes for which no
message is printed.

This fixes bug #14293:

From 6f6b35e133fe4313277b30fc1a7ea313875ea6c9 Mon Sep 17 00:00:00 2001

Subject: macintosh: Don't assume i2c device probing always succeeds

If i2c device probing fails, then there is no driver to dereference
after calling i2c_new_device(). Stop assuming that probing will always
succeed, to avoid NULL pointer dereferences. We have an easier access
to the driver anyway.

Subject: drm/radeon/kms: add support for "Surround View"

"Surround View" is an option in the system bios that
enables the AMD IGP chip in conjunction with a
discrete AMD card.  However, since the IGP vbios is
part of the system bios it is not accessible via the
rom bar or the legacy vga location.  When "Surround View"
is enabled in the system bios, the system bios puts a
copy of the IGP vbios image at the start of vram.

This patch adds support for reading the vbios image out
of vram on IGP cards.

Subject: drm: Delete the DRM_DEBUG_KMS in drm_mode_cursor_ioctl

We can get the corresponding info by adding the boot option of "drm.debug=
0x07". But On some boxes it will print the following message many times in
course of moving mouse. In such case the useful DRM debug info will be flushed.
   >[drm:drm_mode_cursor_ioctl],

Avoid using the DRM_DEBUG_KMS in drm_mode_cursor_ioctl.

support at least on radeon hardware. It adds a new load_lut
hook which can be called once the color map is setup.

Subject: Linux 2.6.32-rc3

I'm skipping -rc2 because the -rc1 Makefile mistakenly said -rc2, so in
order to avoid confusion, I'm jumping from -rc1 to -rc3.  That way, when
'uname' (or an oops report) says 2.6.32-rc2, there's no confusion about
whether people perhaps meant -rc1 or -rc2.

This patch will add support for the 82599 Dual port Backplane
device (0x10f8).  This device has the ability to link in serial (KR) and
parallel (KX4/KX) modes, depending on what the switch capabilities are in
the blade chassis.

Subject: e1000e: swap max hw supported frame size between 82574 and 82583

There appears to have been a mixup in the max supported jumbo frame size
between 82574 and 82583 which ended up disabling jumbo frames on the 82574
as a result.  This patch swaps the two so that this issue is resolved.

This patch fixes http://bugzilla.kernel.org/show_bug.cgi?id=14261

Subject: pktgen: Fix multiqueue handling

It is not currently possible to instruct pktgen to use one selected tx queue.

When Robert added multiqueue support in commit 45b270f8, he added
an interval (queue_map_min, queue_map_max), and his code doesnt take
into account the case of min = max, to select one tx queue exactly.

I suspect a high performance setup on a eight txqueue device wants
to use exactly eight cpus, and assign one tx queue to each sender.

This patchs makes pktgen select the right tx queue, not the first one.

Also updates Documentation to reflect Robert changes.

Subject: ALSA: hda - Fix invalid initializations for ALC861 auto mode

The recent auto-parser doesn't work for machines with a single output
with ALC861, such as Toshiba laptops, because alc_subsystem_id() sets
the hp_pins[0] while it's listed in line_outs[0].
This ends up with the doubled initialization of the same mixer widget,
and it mutes the DAC route because hp_pins has no DAC assigned.

To fix this problem, just check spec->autocfg.hp_outs and speaker_outs
so that they are really detected pins.

Subject: net: Support inclusion of <linux/socket.h> before <sys/socket.h>

The following user-space program fails to compile:

    #include <linux/socket.h>
    #include <sys/socket.h>
    int main() { return 0; }

The reason is that <linux/socket.h> tests __GLIBC__ to decide whether it
should define various structures and macros that are now defined for
user-space by <sys/socket.h>, but __GLIBC__ is not defined if no libc
headers have yet been included.

It seems safe to drop support for libc 5 now.

Subject: tracing: Check total refcount before releasing bufs in profile_enable
 failure

When we call the profile_enable() callback of an event, we release the
shared perf event tracing buffers unconditionnaly in the failure path.
This is wrong because there may be other users of these. Then check the
total refcount before doing this.

Subject: tracing: Use free_percpu instead of kfree

In the event->profile_enable() failure path, we release the per cpu
buffers using kfree which is wrong because they are per cpu pointers.
Although free_percpu only wraps kfree for now, that may change in the
future so lets use the correct way.

Subject: cfq-iosched: fix issue with rq-rq merging and fifo list ordering

cfq uses rq->start_time as the fifo indicator, but that field may
get modified prior to cfq doing it's fifo list adjustment when
a request gets merged with another request. This can cause the
fifo list to become unordered.

Subject: cfq-iosched: fix possible problem with jiffies wraparound

The RR service tree is indexed by a key that is relative to current jiffies.
This can cause problems on jiffies wraparound.

The patch fixes it using time_before comparison, and changing
the add_front path to use a relative number, too.

Subject: block: get rid of kblock_schedule_delayed_work()

It was briefly introduced to allow CFQ to to delayed scheduling,
but we ended up removing that feature again. So lets kill the
function and export, and just switch CFQ back to the normal work
schedule since it is now passing in a '0' delay from all call
sites.

Subject: wext: let get_wireless_stats() sleep

A number of drivers (recently including cfg80211-based ones)
assume that all wireless handlers, including statistics, can
sleep and they often also implicitly assume that the rtnl is
held around their invocation. This is almost always true now
except when reading from sysfs:

  BUG: sleeping function called from invalid context at kernel/mutex.c:280
  in_atomic(): 1, irqs_disabled(): 0, pid: 10450, name: head
  2 locks held by head/10450:

   [<c12844fe>] wireless_show+0x2a/0x4c

Fix this by using the rtnl instead of dev_base_lock.

Subject: sched: Set correct normal_prio and prio values in sched_fork()

normal_prio should be updated if policy changes from RT to
SCHED_MORMAL or if static_prio/nice is changed.

Some paths through sched_fork() ignore this requirement and may
result in normal_prio having an invalid value.

Fixing this issue allows the call to effective_prio() in
wake_up_new_task() to be removed.

Subject: Btrfs: fix deadlock on async thread startup

The btrfs async worker threads are used for a wide variety of things,
including processing bio end_io functions.  This means that when
the endio threads aren't running, the rest of the FS isn't
able to do the final processing required to clear PageWriteback.

The endio threads also try to exit as they become idle and
start more as the work piles up.  The problem is that starting more
threads means kthreadd may need to allocate ram, and that allocation
may wait until the global number of writeback pages on the system is
below a certain limit.

The result of that throttling is that end IO threads wait on
kthreadd, who is waiting on IO to end, which will never happen.

This commit fixes the deadlock by handing off thread startup to a
dedicated thread.  It also fixes a bug where the on-demand thread
creation was creating far too many threads because it didn't take into
account threads being started by other procs.

Subject: ARM: 5742/1: ARM: add debug check for invalid kernel page faults

According to the following in arch/arm/mm/fault.c page faults from
kernel mode are invalid if mmap_sem is already held and there is
no exception handler defined for the faulting instruction:

/*
 * As per x86, we may deadlock here.  However, since the kernel only
 * validly references user space from well defined areas of the code,
 * we can bug out early if this is from code which shouldn't.
 */
if (!down_read_trylock(&mm->mmap_sem)) {
	if (!user_mode(regs) && !search_exception_tables(regs->ARM_pc))
		goto no_context;

Since mmap_sem can be held at arbitrary times by another thread this
also means that any page faults from kernel mode are invalid if no
exception handler is defined for them, regardless whether mmap_sem is
held at the time of fault.

To easier detect code that can trigger the above error, add a check
also for the case where mmap_sem is acquired. As this has an overhead
make it a VM debug check.

Subject: OMAP3: PM: Prevent hang in prcm_interrupt_handler

There are two scenarios where a race condition could result in a hang
in the prcm_interrupt handler. These are:

1). Waiting for PRM_IRQSTATUS_MPU register to clear.
Bit 0 of the PRM_IRQSTATUS_MPU register indicates that a wake-up event
is pending for the MPU. This bit can only be cleared if the all the
wake-up events latched in the various PM_WKST_x registers have been
cleared. If a wake-up event occurred during the processing of the prcm
interrupt handler, after the corresponding PM_WKST_x register was
checked but before the PRM_IRQSTATUS_MPU was cleared, then the CPU
would be stuck forever waiting for bit 0 in PRM_IRQSTATUS_MPU to be
cleared.

2). Waiting for the PM_WKST_x register to clear.
Some power domains have more than one wake-up source. The PM_WKST_x
registers indicate the source of a wake-up event and need to be cleared
after a wake-up event occurs. When the PM_WKST_x registers are read and
before they are cleared, it is possible that another wake-up event
could occur causing another bit to be set in one of the PM_WKST_x
registers. If this did occur after reading a PM_WKST_x register then
the CPU would miss this event and get stuck forever in a loop waiting
for that PM_WKST_x register to clear.

This patch address the above race conditions that would result in a
hang.

Subject: OMAP3: PM: PRCM interrupt: check MPUGRPSEL register

PM_WKST register contents should be ANDed with the contents of the
MPUGRPSEL registers.  Otherwise the MPU PRCM interrupt handler could
wind up clearing wakeup events meant for the IVA PRCM interrupt
handler. A future revision to this code should be to read a cached
version of MPUGRPSEL from the powerdomain code, since PRM reads are
relatively slow.

Subject: OMAP3: PM: PRCM interrupt: only handle selected PRCM interrupts

Clearing wakeup sources is now only done when the PRM indicates a
wakeup source interrupt.  Since we don't handle any other types of
PRCM interrupts right now, warn if we get any other type of PRCM
interrupt.  Either code needs to be added to the PRCM interrupt
handler to react to these, or these other interrupts should be masked
off at init.

Subject: OMAP3: PM: USBHOST: clear wakeup events on both hosts

USBHOST module has 2 fclocks (for HOST1 and HOST2), only one iclock
and only a single bit in the WKST register to indicate a wakeup event.

Because of the single WKST bit, we cannot know whether a wakeup event
was on HOST1 or HOST2, so enable both fclocks before clearing the
wakeup event to ensure both hosts can properly clear the event.

Subject: OMAP3: PM: Enable GPIO module-level wakeups

Currently, only GPIOs in the wakeup domain (GPIOs in bank 0) are
enabled as wakups.  This patch also enables GPIOs in the PER
powerdomain (banks 2-6) to be used as possible wakeup sources.

In addition, this patch ensures that all GPIO wakeups can wakeup
the MPU using the PM_MPUGRPSEL_<pwrdm> registers.

NOTE: this doesn't enable the individual GPIOs as wakeups, this simply
enables the per-bank wakeups at the powerdomain level.

This problem was discovered by Mike Chan when preventing the CORE
powerdomain from going into retention/off.  When CORE was allowed to
hit retention, GPIO wakeups via IO pad were working fine, but when
CORE remained on, GPIO module-level wakeups were not working properly.

To test, prevent CORE from going inactive/retention/off, thus
preventing the IO chain from being armed:

  # echo 3 > /debug/pm_debug/core_pwrdm/suspend

This ensures that GPIO wakeups happen via module-level wakeups and
not via IO pad.

Tested on 3430SDP using the touchscreen GPIO (gpio 2, in WKUP)
Tested on Zoom2 using the QUART interrup GPIO  (gpio 102, in PER)

Also, c.f. OMAP PM wiki for troubleshooting GPIO wakeup issues:

Subject: OMAP3: PM: introduce a new powerdomain walk helper

The 'pwrdm_for_each()' function walks powerdomains with a spinlock
locked, so the the callbacks cannot do anything which may sleep.
This patch introduces a 'pwrdm_for_each_nolock()' helper which does
the same, but without the spinlock locked. This fixes the following
lockdep warning:

o	Move "So where is rcu_write_lock()" comment so that it does
	not come between the rcu_read_unlock() header comment and
	the rcu_read_unlock() definition.

o	Move the module_param statements for blimit, qhimark, and
	qlowmark to immediately follow the corresponding
	definitions.

o	In __rcu_offline_cpu(), move the assignment to rdp_me
	inside the "if" statement, given that rdp_me is not used
	outside of that "if" statement.

Subject: rcu: Clean up code based on review feedback from Josh Triplett, part
 4

These issues identified during an old-fashioned face-to-face code
review extending over many hours.  This group improves an existing
abstraction and introduces two new ones.  It also fixes an RCU
stall-warning bug found while making the other changes.

o	Make RCU_INIT_FLAVOR() declare its own variables, removing
	the need to declare them at each call site.

o	Create an rcu_for_each_leaf() macro that scans the leaf
	nodes of the rcu_node tree.

o	Create an rcu_for_each_node_breadth_first() macro that does
	a breadth-first traversal of the rcu_node tree, AKA
	stepping through the array in index-number order.

o	If all CPUs corresponding to a given leaf rcu_node
	structure go offline, then any tasks queued on that leaf
	will be moved to the root rcu_node structure.  Therefore,
	the stall-warning code must dump out tasks queued on the
	root rcu_node structure as well as those queued on the leaf
	rcu_node structures.

Subject: rcu: Replace the rcu_barrier enum with pointer to call_rcu*()
 function

The rcu_barrier enum causes several problems:

  (1) you have to define the enum somewhere, and there is no
      convenient place,

  (2) the difference between TREE_RCU and TREE_PREEMPT_RCU causes
      problems when you need to map from rcu_barrier enum to struct
      rcu_state,

  (3) the switch statement are large, and

  (4) TINY_RCU really needs a different rcu_barrier() than do the
      treercu implementations.

So replace it with a functionally equivalent but cleaner function
pointer abstraction.

Subject: iSCSI/iBFT: use proper address translation

In virtual environments (namely, Xen Dom0) virt <-> phys and
virt <-> isa-bus translations cannot be freely interchanged (and
even outside such environments it is not really correct to do so).
When looking at memory below 1M, the latter translations should
always be used.

Subject: panic: Fix panic message visibility by calling bust_spinlocks(0)
 before dying

Commit ffd71da4e3f ("panic: decrease oops_in_progress only after
having done the panic") moved bust_spinlocks(0) to the end of the
function, which in practice is never reached.

As a result console_unblank() is not called, and on some systems
the user may not see the panic message.

Move it back up to before the unblanking.

Subject: futex: Fix locking imbalance

Rich reported a lock imbalance in the futex code:

   http://bugzilla.kernel.org/show_bug.cgi?id=14288

It's caused by the displacement of the retry_private label in
futex_wake_op(). The code unlocks the hash bucket locks in the
error handling path and retries without locking them again which
makes the next unlock fail.

Move retry_private so we lock the hash bucket locks when we retry.

Subject: omap: Fix incorrect 730 vs 850 detection

Commit cd92204924fafbd5c7241dfd12ca3176d542e0c5 added
support for omap850. However, the patch accidentally
removed the wrong ifdef:

 #  define cpu_is_omap730()		1
 # endif
 #endif
+#else
+# if defined(CONFIG_ARCH_OMAP850)
+#  undef  cpu_is_omap850
+#  define cpu_is_omap850()		1
+# endif
+#endif

...

 void omap2_check_revision(void);

 #endif    /* defined(CONFIG_ARCH_OMAP2) || defined(CONFIG_ARCH_OMAP3) */
-
-#endif

Instead of removing removing the #endif at the end of the file,
the #endif before #else should have been removed.

But we cannot have multiple #else statements as pointed out by
Alistair Buxton <a.j.buxton@gmail.com>. So the fix is to:

- remove the non-multi-omap special handling, as we need to
  detect between omap730 and omap850 anyways.

- add the missing #endif back to the end of the file

Subject: usb: r8a66597-udc unaligned fifo fix

Rework the r8a66597-udc fifo code to avoid unaligned accesses.

Without this patch unaligned exceptions will degrade the
USB performance. The exceptions come from the fact that
the usb fifo data buffers may be misaligned.

This patch updates the fifo access code to only use
insl()/outsl() and insw()/outsw() in the case of properly
aligned data buffers. The fallback case is that inl()/inw()
are used for misaligned buffer reads together with outb()
that is used for misaligned buffer writes.

Subject: drm/fb: add more correct 8/16/24/32 bpp fb support.

The previous patches had some unwanted side effects, I've fixed
the lack of 32bpp working, and fixed up 16bpp so it should also work.

this also adds the interface to allow the driver to set a preferred
console depth so for example low memory rn50 can set it to 8bpp.
It also catches 24bpp on cards that can't do it and forces 32bpp.

Tested on r100/r600/i945.

Subject: ahci: disable 64bit DMA by default on SB600s

Till now only one board, ASUS M2A-VM, can do 64bit dma with recent
BIOSen.  Enabling 64bit DMA by default already broke three boards.
Enabling 64bit DMA isn't worth these regressions.  Disable 64bit DMA
by default and enable it only on boards which are known to work.

Subject: pata_ali: trivial fix of a very frequent spelling mistake

something-bility is spelled as something-blity
so a grep for 'blit' would find these lines

I broke this one out from the rest as it actually changes
the output of a kernel message - so it could in theory
change the behavior of tools that parse that ouput

Subject: ahci: display all AHCI 1.3 HBA capability flags (v2)

Update the AHCI driver to display all of the HBA capabilities defined in the
AHCI 1.3 specification. Some of these are in a new CAP2 (HBA Capabilities
Extended) register which is only defined on AHCI 1.2 or later. The spec says
that undefined registers should always return 0 on read, but to be safe we
assume a value of 0 unless the controller reports AHCI version 1.2 or later.
The value can also be retrieved through sysfs as with the existing capability
field.

For example, on an Intel Ibex Peak (PCH) controller:

ahci 0000:00:1f.2: flags: 64bit ncq sntf stag pm led clo pmp pio slum part ems
sxs apst

We don't do anything special with the new flags yet.

Also, change the code that displays the flags to use the same bit enumerations
that are used to control actual operation.

Subject: libata: implement more acpi filtering options

Currently libata-acpi can only filter DIPM among SATA feature enables
via _GTF.  This patch adds the capability to filter out FPDMA non-zero
offset, in-order guarantee and auto-activation.

Subject: ahci: filter FPDMA non-zero offset enable for Aspire 3810T

Curiously, Aspire 3810T issues many SATA feature enable commands via
_GTF, of which one is invalid and another is not supported by the
drive.  In the process, it also enables FPDMA non-zero offset.
However, the feature also needs to be supported and enabled from the
controller and it's wrong to enable it from _GTF unless the controller
can do it by default.

Currently, this ends up enabling FPDMA non-zero offset only on the
drive side leading to NCQ command failures and eventual disabling of
NCQ.  This patch makes libata filter out FPDMA non-zero offset enable
for the machine.

This was reported by Marcus Meissner in bnc#522790.

Subject: Input: ad7879 - pass up error codes from probe functions

If the sub-probe functions fail, we need to pass up the error code to the
higher levels from the probe function.  We currently always return 0 even
if there was an error so higher levels don't report problems.

Subject: Input: fix rx51 board keymap

The original driver was written with the KEY() macro defined as (col,
row) instead of (row, col) as defined by the matrix keypad
infrastructure. So the keymap was defined accordingly. Since the
driver that was merged upstream uses the matrix keypad infrastructure,
modify the keymap accordingly.

While we are at it, fix the comments in twl4030.h and define
PERSISTENT_KEY as (r,c) instead of (c, r)

Tested on a RX51 (N900) device.

Subject: [S390] module: fix memory leak in s390 module loader

The s390 version of module_frob_arch_sections allocates additional
syminfos for got and plt offsets. These syminfos are freed on
sucessful module load. If the module fails to load (e.g. missing
dependency when using insmod instead of modprobe) this area is not
freed.
This patch lets module_free free this area. Please note, we have to
set the pointer to NULL since module_free is called several times
from the generic code.

Subject: [S390] Fix memory leak in /proc/cio_ignore

There is a memory leak in /proc/cio_ignore. The iterator is allocated
in cio_ignore_proc_seq_start, but never freed in
cio_ignore_proc_seq_stop, because we cannot use the iterator
that was passed by seqfile. The seqfile interface passes the last
seen iterator to the stop function and not the first one. Since our
next function will return NULL at the end, the iter passed to
cio_ignore_proc_seq_stop is NULL. The original iter has leaked.
The solution is to use seq_open_private.

Found with kmemleak:
unreferenced object 0x1c720580 (size 32):

Subject: [S390] Fix enabled udelay for short delays.

When udelay() gets called with a delay that would expire before the
next clock event it reprograms the clock comparator.
When the interrupt happens the clock comparator won't be resetted
therefore the interrupt condition doesn't get cleared.
The result is an endless timer interrupt loop until the next clock
event would expire (stored in lowcore).
So udelay() usually would wait much longer for small delays than it
should.

Fix this by disabling the local tick which makes sure that the clock
comparator will be resetted when a timer interrupt happens.

Subject: [S390] ftrace: drop nmi protection

The function graph tracer used to have a protection against NMI
while entering a function entry tracing. But this is useless now,
the tracer is reentrant and the ring buffer supports NMI tracing.

Same as 07868b086cca784f4b532fc2ab574ec3a73b468a for x86.

Subject: [S390] Add EX_TABLE for addressing exception in usercopy functions.

This patch adds an EX_TABLE entry to mvc{p|s|os} usercopy functions that
may be called with KERNEL_DS. In combination with collaborative memory
management, kernel pages marked as unused may trigger an adressing exception
in the usercopy functions. This fixes an unhandled addressing exception bug
where strncpy_from_user() is used with len > strnlen and KERNEL_DS, crossing
a page boundary to an unused page.

Subject: [S390] dasd: fix race condition in resume code

There is a race while re-reading the device characteristics. After
cleaning the memory area a cqr is build which reads the device
characteristics. This may take a rather long time and the device
characteristics structure is zero during this. Now it could be
possible that the block tasklet starts working and a new cqr will be
build. The build_cp command refers to the device characteristics
structure and this may lead into a divide by zero exception.
Fix this by re-reading the device characteristics into a temporary
structur and copy the data to the original structure. Also take the
ccwdev_lock.

 functions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Asm routines that end up having size equal to zero are not really
zero sized, and as now we do kernel_maps__fixup_sym_end, at least
for kernel routines this gets fixed.

A similar fixup needs to be done for the userspace bits as well,
but as this fixup started only because in /proc/kallsyms we don't
have the end address nor the function size, it appeared here first.

Subject: ALSA: hda - Don't pick up invalid HP pins in alc_subsystem_id()

alc_subsystem_id() tries to pick up a headphone pin if not configured,
but this caused side-effects as the problem in commit
15870f05e90a365f8022da416e713be0c5024e2f.

This patch fixes the driver behavior to pick up invalid HP pins; at least,
the pins that are listed as the primary outputs aren't taken any more.

Subject: perf_event: Provide vmalloc() based mmap() backing

Some architectures such as Sparc, ARM and MIPS (basically
everything with flush_dcache_page()) need to deal with dcache
aliases by carefully placing pages in both kernel and user maps.

These architectures typically have to use vmalloc_user() for this.

However, on other architectures, vmalloc() is not needed and has
the downsides of being more restricted and slower than regular
allocations.

Subject: trace: Fix missing assignment in trace_ctxwake_*

The state char variable S should be reassigned, if S == 0.

We are missing the state of the task that is going to sleep for the
context switch events (in the raw mode).

Fortunately the problem arises with the sched_switch/wake_up
tracers, not the sched trace events.

The formers are legacy now. But still, that was buggy.

Subject: sound: via82xx: move DXS volume controls to PCM interface

The "VIA DXS" controls are actually volume controls that apply to the
four PCM substreams, so we better indicate this connection by moving the
controls to the PCM interface.

Commit b452e08e73c0e3dbb0be82130217be4b7084299e in 2.6.30 broke the
restoring of these volumes by "alsactl restore" that most distributions
use; the renaming in this patch cures that regression by preventing
alsactl from applying the old, wrong volume levels to the new controls.

Subject: Btrfs: fix possible softlockup in the allocator

Like the cluster allocating stuff, we can lockup the box with the normal
allocation path.  This happens when we

1) Start to cache a block group that is severely fragmented, but has a decent
amount of free space.
2) Start to commit a transaction
3) Have the commit try and empty out some of the delalloc inodes with extents
that are relatively large.

The inodes will not be able to make the allocations because they will ask for
allocations larger than a contiguous area in the free space cache.  So we will
wait for more progress to be made on the block group, but since we're in a
commit the caching kthread won't make any more progress and it already has
enough free space that wait_block_group_cache_progress will just return.  So,
if we wait and fail to make the allocation the next time around, just loop and
go to the next block group.  This keeps us from getting stuck in a softlockup.
Thanks,

Subject: futex: Nullify robust lists after cleanup

The robust list pointers of user space held futexes are kept intact
over an exec() call. When the exec'ed task exits exit_robust_list() is
called with the stale pointer. The risk of corruption is minimal, but
still it is incorrect to keep the pointers valid. Actually glibc
should uninstall the robust list before calling exec() but we have to
deal with it anyway.

Nullify the pointers after [compat_]exit_robust_list() has been
called.

Subject: omap: iovmm: Add missing mutex_unlock

I was using Coccinelle with the mutex_unlock semantic patch, and it
unconvered this problem. It appears to be a valid missing unlock issue.
This change should correct it by moving the unlock below the label.

This patch is against the mainline kernel.

Subject: omapfb: Condition mutex acquisition

This fixes a bug introduced by this commit ID:

  commit 537a1bf059fa312355696fa6db80726e655e7f17
  Author: Krzysztof Helt <krzysztof.h1@wp.pl>
  Date:   Tue Jun 30 11:41:29 2009 -0700

    fbdev: add mutex for fb_mmap locking

In which a mutex was added when changing smem_start and smem_len fields,
so the mutex inside the fb_mmap() call is actually used.

The problem was that set_fb_fix, which modifies the above 2 fields,
was called before and after registering the framebuffer,
which when used before registration, lead to a failed attempt to
use an uninitialized mutex.

Solution: Don't use mutex before framebuffer registration.

Subject: PCI PM: Read device power state from register after updating it

After attempting to change the power state of a PCI device
pci_raw_set_power_state() doesn't check if the value it wrote into
the device's PCI_PM_CTRL register has been stored in there, but
unconditionally modifies the device's current_state field to reflect
the change.  This may cause problems to happen if the power state of
the device hasn't been changed in fact, because it will make the PCI
PM core make a wrong assumption.

To prevent such situations from happening modify
pci_raw_set_power_state() so that it reads the device's PCI_PM_CTRL
register after writing into it and uses the value read from the
register to update the device's current_state field.  Also make it
print a message saying that the device refused to change its power
state as requested (returning an error code in such cases would cause
suspend regressions to appear on some systems, where device drivers'
suspend routines return error codes if pci_set_power_state() fails).

Subject: block: Seperate read and write statistics of in_flight requests v2

Commit a9327cac440be4d8333bba975cbbf76045096275 added seperate read
and write statistics of in_flight requests. And exported the number
of read and write requests in progress seperately through sysfs.

But  Corrado Zoccolo <czoccolo@gmail.com> reported getting strange
output from "iostat -kx 2". Global values for service time and
utilization were garbage. For interval values, utilization was always
100%, and service time is higher than normal.

So this was reverted by commit 0f78ab9899e9d6acb09d5465def618704255963b

The problem was in part_round_stats_single(), I missed the following:
        if (now == part->stamp)
                return;

-       if (part->in_flight) {
+       if (part_in_flight(part)) {
                __part_stat_add(cpu, part, time_in_queue,
                                part_in_flight(part) * (now - part->stamp));
                __part_stat_add(cpu, part, io_ticks, (now - part->stamp));

With this chunk included, the reported regression gets fixed.

Subject: [CIFS] Fixing to avoid invalid kfree() in cifs_get_tcp_session()

trivial bug in fs/cifs/connect.c .
The bug is caused by fail of extract_hostname()
when mounting cifs file system.

This is the situation when I noticed this bug.

% sudo mount -t cifs //192.168.10.208 mountpoint -o options...

The reason of this bug is that the error handling code of
cifs_get_tcp_session()
calls kfree() when corresponding kmalloc() failed.
(The kmalloc() is called by extract_hostname().)

Subject: cfq-iosched: fix the slice residual sign

We should subtract the slice residual from the rb tree key, since
a negative residual count indicates that the cfqq overran its slice
the last time. Hence we want to add the overrun time, to position
it a bit further away in the service tree.

Subject: NFS: Fix a default mount regression...

With the recent spate of changes, the nfs protocol version will now default
to 2 instead of 3, while the mount protocol version defaults to 3.

The following patch should ensure the defaults are consistent with the
previous defaults of vers=3,proto=tcp,mountvers=3,mountproto=tcp.

This fixes the bug

The recent changeset 53a0b9c4c99ab0085a06421f71592722e5b3fd5f (NFS: Replace
nfs_parse_ip_address() with rpc_pton()) broke nfs_remount, since the call
to rpc_pton() will zero out the port number in data->nfs_server.address.

This is actually due to a bug in nfs_remount: it should be looking at the
port number in nfs_server.port instead...

Subject: nfs: Avoid overrun when copying client IP address string

As seen in <http://bugs.debian.org/549002>, nfs4_init_client() can
overrun the source string when copying the client IP address from
nfs_parsed_mount_data::client_address to nfs_client::cl_ipaddr.  Since
these are both treated as null-terminated strings elsewhere, the copy
should be done with strlcpy() not memcpy().

Fix a typo which causes try_location() to use the wrong length argument
when calling nfs_parse_server_name(). This again, causes the initialisation
of the mount's sockaddr structure to fail.

Also ensure that if nfs4_pathname_string() returns an error, then we pass
that error back up the stack instead of ENOENT.

Subject: be2net: Bug fix to properly update ethtool tx-checksumming after
 ethtool -K <ifname> tx off

This is a fix for a bug which was a result of wrong use of checksum offload flag.
The status of tx-checksumming was not changed from on to off
after a 'ethtool -K <ifname> tx off' operation.
Use the proper checksum offload flag NETIF_F_HW_CSUM instead of
NETIF_F_IP_CSUM and NETIF_F_IPV6_CSUM.
Patch is against net-2.6 tree.

Subject: libata: fix incorrect link online check during probe

While trying to work around spurious detection retries for
non-existent devices on slave links, commit
816ab89782ac139a8b65147cca990822bb7e8675 incorrectly added link
offline check logic before ata_eh_thaw() was called.  This means that
if an occupied link goes down briefly at the time that offline check
was performed, device class will be cleared to ATA_DEV_NONE and libata
wouldn't retry thus failing detection of the device.

The offline check should be done after the port is thawed together
with online check so that such link glitches can be detected by the
interrupt handler and handled properly.

Subject: isdn: accept CAPI Informational Info values as success

Info values in the 0x00xx range are defined in the CAPI standard
as "Informational, message processed successfully". Therefore a
CONNECT_B3_CONF message with an Info value in that range should
open an NCCI just as with Info==0.

Subject: isdn: avoid races in capidrv

In several places, capidrv sends a CAPI message to the ISDN
device and then updates its internal state accordingly.
If the response message from the device arrives before the
state is updated, it may be rejected or processed incorrectly.
Avoid these races by updating the state before emitting the
message.

Being able to change the debugmode module parameter of capidrv on the
fly is quite useful for debugging and doesn't do any harm.

Subject: gigaset: linearize skb

The code of the Gigaset driver assumes that sk_buff-s coming
from the ISDN4Linux subsystem are always linear. Explicitly
calling skb_linearize() is cheap if they are, but much more
robust in case they ever aren't.

Subject: rcu: Move rcu_barrier() to rcutree

Move the existing rcu_barrier() implementation to rcutree.c,
consistent with the fact that the rcu_barrier() implementation is
tied quite tightly to the RCU implementation.

This opens the way to simplify and fix rcutree.c's rcu_barrier()
implementation in a later patch.

Subject: rcu: Make hot-unplugged CPU relinquish its own RCU callbacks

The current interaction between RCU and CPU hotplug requires that
RCU block in CPU notifiers waiting for callbacks to drain.

This can be greatly simplified by having each CPU relinquish its
own callbacks, and for both _rcu_barrier() and CPU_DEAD notifiers
to adopt all callbacks that were previously relinquished.

This change also eliminates the possibility of certain types of
hangs due to the previous practice of waiting for callbacks to be
invoked from within CPU notifiers.  If you don't every wait, you
cannot hang.

Subject: rcu: Place root rcu_node structure in separate lockdep class

Before this patch, all of the rcu_node structures were in the same lockdep
class, so that lockdep would complain when rcu_preempt_offline_tasks()
acquired the root rcu_node structure's lock while holding one of the leaf
rcu_nodes' locks.

This patch changes rcu_init_one() to use a separate
spin_lock_init() for the root rcu_node structure's lock than is
used for that of all of the rest of the rcu_node structures, which
puts the root rcu_node structure's lock in its own lockdep class.

Subject: Blackfin: convert to use arch_gettimeoffset()

Convert Blackfin to use GENERIC_TIME via the arch_getoffset()
infrastructure, reducing the amount of arch specific code we need to
maintain.

I've taken my best swing at converting this, but I'm not 100% confident
I got it right.  My cross-compiler is now out of date (gcc4.2) so I
wasn't able to check if it compiled. Any assistance from arch
maintainers or testers to get this merged would be great.

Subject: Blackfin: mass clean up of copyright/licensing info

Bill Gatliff & David Brownell pointed out we were missing some
copyrights, and licensing terms in some of the files in
./arch/blackfin, so this fixes things, and cleans them up.

It also removes:
 - verbose GPL text(refer to the top level ./COPYING file)
 - file names (you are looking at the file)
 - bug url (it's in the ./MAINTAINERS file)
 - "or later" on GPL-2, when we did not have that right

It also allows some Blackfin-specific assembly files to be under a BSD
like license (for people to use them outside of Linux).

The asm/irq.h header uses anomaly defines, but doesn't make sure to
explicitly include the anomaly header for them.

Subject: Blackfin: cplbinfo: drop d_path() hacks

The cplbinfo was using d_path() to figure out which cpu/cplb was being
parsed.  As Al pointed out, this isn't exactly reliable as it assumes the
static VFS path to be unchanged, and it's just poor form.  So use the
proc_create_data() to properly (and internally) pass the exact cpu/cplb
requested to the parser function.

Subject: tg3: Fix phylib locking strategy

Felix Radensky noted that chip resets were generating stack trace dumps.
This is because the driver is attempting to acquire the mdio bus mutex
while holding the tp->lock spinlock.  The fix is to change the code such
that every phy access takes the tp->lock spinlock instead.

Not all pasemi mac interfaces can have a phy attached.
For example, XAUI has no phy and phydev is NULL for it.
In this case ethtool get settings causes kernel crash.
Fix it by returning -EOPNOTSUPP if there's no PHY attached.

Subject: ethoc: fix buffer address mapping

The pointer address in buffer descriptors is physical address. The
pointer that processor used to access packet is virtual address.

Though the higher bits of pointer address used by the MAC may be
truncated to zero in special case, it is not always true in larger
designs.

Subject: ethoc: align received packet to make IP header at word boundary

The packet buffer is allocated at 4 bytes boundary, but the IP header
length and version bits is located at byte 14. These bit fields access
as 32 bits word and caused exception on processors that do not support
unaligned access.

The patch adds 2 bytes offset to make the bit fields word aligned.

Subject: ethoc: use system memory as buffer

This patch enabled the ethoc to allocate system memory as buffer
when there is no dedicated buffer memory.

Some hardware designs may not have dedicated buffer memory such as
on chip or off chip SRAM. In this case, only one memory resource is
supplied in the platform data instead of two. Then a DMA buffer can
be allocated from system memory and used for the transfer.

Subject: NOHZ: update idle state also when NOHZ is inactive

Commit f2e21c9610991e95621a81407cdbab881226419b had unfortunate side
effects with cpufreq governors on some systems.

If the system did not switch into NOHZ mode ts->inidle is not set when
tick_nohz_stop_sched_tick() is called from the idle routine. Therefor
all subsequent calls from irq_exit() to tick_nohz_stop_sched_tick()
fail to call tick_nohz_start_idle(). This results in bogus idle
accounting information which is passed to cpufreq governors.

Set the inidle flag unconditionally of the NOHZ active state to keep
the idle time accounting correct in any case.

Subject: sis5513: fix PIO setup for ATAPI devices

Clear prefetch setting before potentially (re-)enabling it in
config_drive_art_rwp() so the transition of the device type on
the port from ATA to ATAPI (i.e. during warm-plug operation)
is handled correctly.

This is a really old bug (it probably goes back to very early
days of the driver) but it was only affecting warm-plug operation
until the recent "ide: try to use PIO Mode 0 during probe if
possible" change (commit 6029336426a2b43e4bc6f4a84be8789a047d139e).

(commit 6029336426a2b43e4bc6f4a84be8789a047d139e) so the revert was

Subject: ARM: 5745/1: Change ep93xx gpio_irq static inlines to macros

From: Ryan Mallon <ryan@bluewatersys.com>

Change the gpio_to_irq and irq_to_gpio static inline functions to
macros so that they can be used in variable initialisers.

Subject: ARM: 5746/1: Handle possible translation errors in ARMv6/v7
 coherent_user_range

This is needed because applications using the sys_cacheflush system call
can pass a memory range which isn't mapped yet even though the
corresponding vma is valid. The patch also adds unwinding annotations
for correct backtraces from the coherent_user_range() functions.

Subject: ARM: 5747/1: Fix the start_pg value in free_memmap()

If sparsemem is enabled, the start_pfn passed to the free_memmap()
function corresponds to an area of memory not known to the kernel and
pfn_to_page returns a wrong value. The (start_pfn - 1), however, is
known to the kernel.

Both iPaqs h3100 and h3600 currently share the same source
file - h3600.c  But Makefile builds it only if CONFIG_SA1100_H3600
selected, so selecting just CONFIG_SA1100_H3100 results in
"no machine record defined" message and aborted compilation.

Fix it.

Subject: ALSA: hda - Fix yet another auto-mic bug in ALC268

Since patch_alc268() doesn't call set_capture_mixer() (due to its h/w
design different from other siblings), it needs to call fixup_automic_adc()
explicitly to set up the auto-mic routing.  Otherwise the indices for
int/ext mics aren't set properly.

Subject: amd64_edac: simple fix to allow reporting of CECC errors

This allows the errors to be further decoded and mapped to csrows.
Tested with ECC debug dimms and an Rev F cpu based system.

Subject: amd64_edac: fix chip select handling

Different processor families support a different number of chip selects.
Handle this in a family-dependent way with the proper values assigned at
init time (see amd64_set_dct_base_and_mask).

Remove _DCSM_COUNT defines since they're used at one place and originate
from public documentation.

Subject: amd64_edac: fix DRAM base and limit extraction

On Fam10h and above, F1x[1, 0][7C:40] are DRAM Base/Limit registers
which specify the destination node of a DRAM address. Those address
boundaries are being extracted into ->dram_base[] and ->dram_limit[].
Correct the extraction masks to match the respective address bits.

Subject: amd64_edac: beef up DRAM error injection

When injecting DRAM ECC errors (F3xBC_x8), EccVector[15:0] is a bitmask
of which bits should be error injected when written to and holds the
payload of 16-bit DRAM word when read, respectively.

Add /sysfs members to show the DRAM ECC section/word/vector.

Fail wrong injection values entered over /sysfs instead of truncating
them.

Device needs a big pref mmio, but BIOS doesn't allocate mmio to it aside
from a small MMIO range.  Later, the kernel will not allocate resources to
that to the device:

that range.  With the patch we get:

Subject: PCI: Prevent AER driver from being loaded on non-root port PCIE
 devices

A bug was seen on boards using a PLX 8518 switch device which advertises
AER on each of it's transparent bridges. The AER driver was loaded for
each bridge and this driver tried to access the AER source ID register
whenever an interrupt occured on the shared PCI INTX lines. The source
ID register does not exist on non root port PCIE device's  which
advertise AER and trying to access this register causes a unsupported
request error on the bridge. Thus, when the next interrupt occurs,
another error is found and the non existent source ID register is
accessed again, and so it goes on.

The result is a spammed dmesg with unsupported request PCI express
errors on the bridge device that the AER driver is loaded against.

CFQ enables idle only for processes that think less than the allowed
idle time. Since idle time is lower for seeky queues, we should use the
correct value in the comparison.

Subject: [IA64] Squeeze ticket locks back into 4 bytes.

Linus pointed out that other people have spent large amounts of time
and effort to optimize the layout of frequently used structures. Often
these have embedded locks, and the assumption is that a lock takes
4 bytes.  Linus also pointed out how to work with the limited options
for atomic instructions on Itanium.

Subject: futex: fix requeue_pi key imbalance

If futex_wait_requeue_pi() wakes prior to requeue, we drop the
reference to the source futex_key twice, once in
handle_early_requeue_pi_wakeup() and once on our way out.

Remove the drop from the handle_early_requeue_pi_wakeup() and keep
the get/drops together in futex_wait_requeue_pi().

Subject: tracing: correct module boundaries for ftrace_release

When the module is about the unload we release its call records.
The ftrace_release function was given wrong values representing
the module core boundaries, thus not releasing its call records.

Plus making ftrace_release function module specific.

Subject: mac80211: fix vlan and optimise RX

When receiving data frames, we can send them only to
the interface they belong to based on transmitting
station (this doesn't work for probe requests). Also,
don't try to handle other frames for AP_VLAN at all
since those interface should only receive data.

Additionally, the transmit side must check that the
station we're sending a frame to is actually on the
interface we're transmitting on, and not transmit
packets to functions that live on other interfaces,
so validate that as well.

Another bug fix is needed in sta_info.c where in the
VLAN case when adding/removing stations we overwrite
the sdata variable we still need.

Subject: iwlwifi: incorrect method used for finding valid OTP blocks

The address stored in the next link address is a word address but when
reading the OTP blocks, a byte address is used. Also if the blocks are
full and the last link pointer is not zero, then none of the blocks are
valid so return an error.

The algorithm is simply valid blocks have a next address and that
address's contents is zero.

Using the wrong address for the next link address gets arbitrary data,
obviously. In cases seen, the first block is considered valid when it is not.

If the block has in fact been invalidated there may be old data or
there may be no data, bad data, or partial data, there is no way of
telling. Without this patch it is possible that a device with valid OTP data
is unable to work.

Subject: b43: do not stack-allocate pio rx/tx header and tail buffers

The DMA-API debugging facility complains about b43 mapping memory from
stack for SDIO-based cards.

Indeed, b43 currently allocates the PIO RX/TX header and tail buffers
from stack. The solution here is to use heap-allocated buffers instead.

Subject: RDMA/iwcm: Don't call provider reject func with irqs disabled

In commit cb58160e ("RDMA/iwcm: Reject the connection when the cm_id
is destroyed") a call to the provider's reject handler was added to
destroy_cm_id() to fix a provider endpoint leak.  This call needs to
be done with interrupts enabled.  So unlock and relock around this
call.  This is safe because:

1) the provider will do nothing with this endpoint until the iwcm either
   accepts or rejects.
2) the lock is only released after the iwcm state is changed, so an
   errant iwcm app that is destroying -and- rejecting the connection
   concurrently will get a failure on one of the calls.

Subject: RDMA/cxgb3: Handle NULL inetdev pointer in iwch_query_port()

in_dev_get() can return NULL.  If it does, iwch_query_port() will crash.
Handle the NULL case by mapping it to port state INIT.

Subject: RDMA/addr: Fix resolution of local IPv6 addresses

This patch allows a local IPv6 address to be resolved by rdma_cm.

To reproduce the problem:

 $ rping -s -v -a ::0  &
 $ rping -c -v -a <IPv6 address local to this system>
 rdma_resolve_addr error -1

Local IPv6 address was obtained with "ip addr show ib0"

Subject: drm/radeon/kms: Fallback to non AGP when acceleration fails to
 initialize (v2)

When GPU acceleration is not working with AGP try to fallback to non
AGP GART (either PCI or PCIE GART). This should make KMS failure on
AGP less painfull. We still need to find out what is wrong when AGP
fails but at least user have a lot of more chances to get a working
configuration with acceleration. This patch also cleanup R600/RV770
fallback path so they use same code as others asics. Version 2
factorize agp disabling logic to avoid code duplication and bugs.

From 1a029b768f9d4a001501bd18d6ba08297ae912fd Mon Sep 17 00:00:00 2001
From: Jerome Glisse <jglisse@redhat.com>

Subject: drm/radeon/kms: Fix AGP support for R600/RV770 family (v2)

For AGP to work unmapped access must cover VRAM & AGP as
AGP is treated like VRAM by the GPU (ie physical address).
This patch properly setup the virtual memory system aperture
to cover AGP if AGP is enabled. It seems that there is memory
corruption after resume when using AGP (RV770 seems unaffected
thought). Version 2 just fix merge issue with updated AGP
fallback patch.

Subject: tracing: user local buffer variable for trace branch tracer

Just using the tr->buffer for the API to trace_buffer_lock_reserve
is not good enough. This is because the tr->buffer may change, and we
do not want to commit with a different buffer that we reserved from.

This patch uses a local variable to hold the buffer that was used to
reserve and commit with.

Subject: Blackfin: fix framebuffer mmap bug for nommu

The patch added a special get_unmapped_area for framebuffer which
was hooked to the file ops in drivers/video/fbmem.c.

This is needed since v2.6.29-rc1 where nommu vma management was
updated, and mmap of framebuffer caused kernel BUG panic. You may turn
on "Debug the global anon/private NOMMU mapping region tree" config to
such message.

As Documentation/nommu-mmap.txt said,
"To provide shareable character device support, a driver must provide
a file->f_op->get_unmapped_area() operation. The mmap() routines will
call this to get a proposed address for the mapping."

With this change, user space should call mmap for framebuffer using
shared map. Or it can try shared map first, then private map if
failed. This shared map usage is now consistent between mmu and nommu.

The sys_ file may not be a good place for this patch. But there is a
similar one for sparc. I tested a similar patch on nios2nommu, though
I don't have a blackfin board to test.

Subject: Blackfin: convert to GENERIC_HARDIRQS_NO__DO_IRQ

Blackfin already sets proper flow handlers on all IRQs, and we don't rely
on __do_IRQ, therefore we can simply select GENERIC_HARDIRQS_NO__DO_IRQ.

Subject: cfq-iosched: avoid probable slice overrun when idling

If the average think time is larger than the remaining time slice
for any given queue, don't allow it to idle. A succesful idle also
means that we need to dispatch and complete a request, so if we don't
even have time left for the idle process, we would overrun the slice
in any case.

Subject: ALSA: ICE1712/24 - Change the Multi Track Peak control (level meters)
 from MIXER to PCM type

* PLEASE NOTE - this change requires the corresponding update of
  envy24control for ice1712 - kind of an ABI change.
* The "Multi Track Peak" control is read-only level meters indicator.
* The control is VERY confusing to most users since it is currently displayed
  in regular mixers. E.g. alsamixer ignores its read-only status
  and allows changing the levels with keys which makes no sense.

Subject: ALSA: ice1724: increase SPDIF and independent stereo buffer sizes

Increase the default and maximum PCM buffer prellocation size for ice1724's
SPDIF and independent stereo pair outputs to 256K, which is the hardware's
maximum supported size. This allows a reduction in interrupt rate and
potentially power usage when an application is not latency-critical.

Subject: ksm: more on default values

Adjust the max_kernel_pages default to a quarter of totalram_pages,
instead of nr_free_buffer_pages() / 4: the KSM pages themselves come from
highmem, and even on a 16GB PAE machine, 4GB of KSM pages would only be
pinning 32MB of lowmem with their rmap_items, so no need for the more
obscure calculation (nor for its own special init function).

There is no way for the user to switch KSM on if CONFIG_SYSFS is not
enabled, so in that case default run to KSM_RUN_MERGE.

Update KSM Documentation and Kconfig to reflect the new defaults.

Subject: cgroups: update documentation of cgroups tasks and procs files

Update documentation of cgroups tasks and procs files

Document the cgroup.procs file.

Clarify the semantics of the cgroup.procs and tasks files.  Although the
current cgroup.procs interface returns a sorted and uniqified list of
pids, potential future performance enhancements could result in those
properties being removed - explicitly document this aspect of the API.

There are no existing users of cgroup.procs, so compatibility isn't an
issue.  There are users of the "tasks" file, but none that would appear to
break in the event of the sorted property being broken.  The standard
"libcpuset" explicitly sorts the results of reading from the tasks file,
and "libcg" and other users don't appear to care about ordering.

Subject: mmc: sdio: don't require CISTPL_VERS_1 to contain 4 strings

The PC Card 8.0 specification (vol.  4, section 3.2.10) says the
TPLLV1_INFO field of the CISTPL_VERS_1 tuple must contain 4 strings.  Some
cards don't have all 4 so just parse as many as we can.

Subject: mm, perf_event: Make vmalloc_user() align base kernel virtual address
 to SHMLBA

When a vmalloc'd area is mmap'd into userspace, some kind of
co-ordination is necessary for this to work on platforms with cpu
D-caches which can have aliases.

Otherwise kernel side writes won't be seen properly in userspace
and vice versa.

If the kernel side mapping and the user side one have the same
alignment, modulo SHMLBA, this can work as long as VM_SHARED is
shared of VMA and for all current users this is true.  VM_SHARED
will force SHMLBA alignment of the user side mmap on platforms with
D-cache aliasing matters.

The bulk of this patch is just making it so that a specific
alignment can be passed down into __get_vm_area_node().  All
existing callers pass in '1' which preserves existing behavior.
vmalloc_user() gives SHMLBA for the alignment.

As a side effect this should get the video media drivers and other
vmalloc_user() users into more working shape on such systems.

Subject: x86, timers: Check for pending timers after (device) interrupts

Now that range timers and deferred timers are common, I found a
problem with these using the "perf timechart" tool. Frans Pop also
reported high scheduler latencies via LatencyTop, when using
iwlagn.

It turns out that on x86, these two 'opportunistic' timers only get
checked when another "real" timer happens. These opportunistic
timers have the objective to save power by hitchhiking on other
wakeups, as to avoid CPU wakeups by themselves as much as possible.

The change in this patch runs this check not only at timer
interrupts, but at all (device) interrupts. The effect is that:

 1) the deferred timers/range timers get delayed less

 2) the range timers cause less wakeups by themselves because
    the percentage of hitchhiking on existing wakeup events goes up.

I've verified the working of the patch using "perf timechart", the
original exposed bug is gone with this patch. Frans also reported
success - the latencies are now down in the expected ~10 msec
range.

Subject: NFSv4: Kill nfs4_renewd_prepare_shutdown()

The NFSv4 renew daemon is shared between all active super blocks that refer
to a particular NFS server, so it is wrong to be shutting it down in
nfs4_kill_super every time a super block is destroyed.

This patch therefore kills nfs4_renewd_prepare_shutdown altogether, and
leaves it up to nfs4_shutdown_client() to also shut down the renew daemon
by means of the existing call to nfs4_kill_renewd().

From f9581b1443abac50c90168301d40a7734b13a5dc Mon Sep 17 00:00:00 2001

Subject: xfs: implement ->dirty_inode to fix timestamp handling

This is picking up on Felix's repost of Dave's patch to implement a
.dirty_inode method.  We really need this notification because
the VFS keeps writing directly into the inode structure instead
of going through methods to update this state.  In addition to
the long-known atime issue we now also have a caller in VM code
that updates c/mtime that way for shared writeable mmaps.  And
I found another one that no one has noticed in practice in the FIFO
code.

So implement ->dirty_inode to set i_update_core whenever the
inode gets externally dirtied, and switch the c/mtime handling to
the same scheme we already use for atime (always picking up
the value from the Linux inode).

Note that this patch also removes the xfs_synchronize_atime call
in xfs_reclaim it was superflous as we already synchronize the time
when writing the inode via the log (xfs_inode_item_format) or the
normal buffers (xfs_iflush_int).

In addition also remove the I_CLEAR check before copying the Linux
timestamps - now that we always have the Linux inode available
we can always use the timestamps in it.

Also switch to just using file_update_time for regular reads/writes -
that will get us all optimization done to it for free and make
sure we notice early when it breaks.

Subject: xfs: fix xfs_quiesce_data

We need to do a synchronous xfs_sync_fsdata to make sure the superblock
actually is on disk when we return.

Also remove SYNC_BDFLUSH flag to xfs_sync_inodes because that particular
flag is never checked.

Move xfs_filestream_flush call later to only release inodes after they
have been written out.

Subject: xfs: cleanup ->sync_fs

Sort out ->sync_fs to not perform a superblock writeback for the wait = 0 case
as that is just an optional first pass and the superblock will be written back
properly in the next call with wait = 1.  Instead perform an opportunistic
quota writeback to have less work later.  Also remove the freeze special case
as we do a proper wait = 1 call in the freeze code anyway.

Also rename the function to xfs_fs_sync_fs to match the normal naming
convention, update comments and avoid calling into the laptop_mode logic on
an error.

Subject: xfs: mark inodes dirty before issuing I/O

To make sure they get properly waited on in sync when I/O is in flight and
we latter need to update the inode size.  Requires a new helper to check if an
ioend structure is beyond the current EOF.

Subject: xfs: make sure xfs_sync_fsdata covers the log

We want to always cover the log after writing out the superblock, and
in case of a synchronous writeout make sure we actually wait for the
log to be covered.  That way a filesystem that has been sync()ed can
be considered clean by log recovery.

Subject: fix readahead calculations in xfs_dir2_leaf_getdents()

This is for bug #850,
http://oss.sgi.com/bugzilla/show_bug.cgi?id=850
XFS file system segfaults , repeatedly and 100% reproducable in 2.6.30 , 2.6.31

The above only showed up on a CONFIG_XFS_DEBUG=y kernel, because
xfs_bmapi() ASSERTs that it has been asked for at least one map,

and it was getting 0.

The root cause is that our guesstimated "bufsize" from xfs_file_readdir
was fairly small, and the

		bufsize -= length;

in the loop was going negative - except bufsize is a size_t, so it
was wrapping to a very large number.

Then when we did
		ra_want = howmany(bufsize + mp->m_dirblksize,
				  mp->m_sb.sb_blocksize) - 1;

with that very large number, the (int) ra_want was coming out
negative, and a subsequent compare:

		if (1 + ra_want > map_blocks ...

was coming out -true- (negative int compare w/ uint) and we went
back to xfs_bmapi() for more, even though we did not need more,
and asked for 0 maps, and hit the ASSERT.

We have kind of a type mess here, but just keeping bufsize from
going negative is probably sufficient to avoid the problem.

Subject: Btrfs: delay clearing EXTENT_DELALLOC for compressed extents

When compression is on, the cow_file_range code is farmed off to
worker threads.  This allows us to do significant CPU work in parallel
on SMP machines.

But it is a delicate balance around when we clear flags and how.  In
the past we cleared the delalloc flag immediately, which was safe
because the pages stayed locked.

But this is causing problems with the newest ENOSPC code, and with the
recent extent state cleanups we can now clear the delalloc bit at the
same time the uncompressed code does.

Subject: Btrfs: release delalloc reservations on extent item insertion

This patch fixes an issue with the delalloc metadata space reservation
code.  The problem is we used to free the reservation as soon as we
allocated the delalloc region.  The problem with this is if we are not
inserting an inline extent, we don't actually insert the extent item until
after the ordered extent is written out.  This patch does 3 things,

1) It moves the reservation clearing stuff into the ordered code, so when
we remove the ordered extent we remove the reservation.
2) It adds a EXTENT_DO_ACCOUNTING flag that gets passed when we clear
delalloc bits in the cases where we want to clear the metadata reservation
when we clear the delalloc extent, in the case that we do an inline extent
or we invalidate the page.
3) It adds another waitqueue to the space info so that when we start a fs
wide delalloc flush, anybody else who also hits that area will simply wait
for the flush to finish and then try to make their allocation.

This has been tested thoroughly to make sure we did not regress on
performance.

Subject: Btrfs: async delalloc flushing under space pressure

This patch moves the delalloc flushing that occurs when we are under space
pressure off to a async thread pool.  This helps since we only free up
metadata space when we actually insert the extent item, which means it takes
quite a while for space to be free'ed up if we wait on all ordered extents.
However, if space is freed up due to inline extents being inserted, we can
wake people who are waiting up early, and they can finish their work.

Subject: Btrfs: optimize fsync for the single writer case

This patch optimizes the tree logging stuff so it doesn't always wait 1 jiffie
for new people to join the logging transaction if there is only ever 1 writer.
This helps a little bit with latency where we have something like RPM where it
will fdatasync every file it writes, and so waiting the 1 jiffie for every
fdatasync really starts to add up.

+What:	Support for VMware's guest paravirtuliazation technique [VMI] will be
+	dropped.
+When:	2.6.37 or earlier.
+Why:	With the recent innovations in CPU hardware acceleration technologies
+	from Intel and AMD, VMware ran a few experiments to compare these
+	techniques to guest paravirtualization technique on VMware's platform.
+	These hardware assisted virtualization techniques have outperformed the
+	performance benefits provided by VMI in most of the workloads. VMware
+	expects that these hardware features will be ubiquitous in a couple of
+	years, as a result, VMware has started a phased retirement of this
+	feature from the hypervisor. We will be removing this feature from the
+	Kernel too. Right now we are targeting 2.6.37 but can retire earlier if
+	technical reasons (read opportunity to remove major chunk of pvops)
+	arise.
+
+	Please note that VMI has always been an optimization and non-VMI kernels
+	still work fine on VMware's platform.
+	Latest versions of VMware's product which support VMI are,
+	Workstation 7.0 and VSphere 4.0 on ESX side, future maintainence
+	releases for these products will continue supporting VMI.
+
+	For more details about VMI retirement take a look at this,

Subject: sh: Don't allocate smaller sized mappings on every iteration

Currently, we've got the less than ideal situation where if we need to
allocate a 256MB mapping we'll allocate four entries like so,

	 entry 1: 128MB
	 entry 2:  64MB
	 entry 3:  16MB
	 entry 4:  16MB

This is because as we execute the loop in pmb_remap() we will
progressively try mapping the remaining address space with smaller and
smaller sizes. This isn't good because the size we use on one iteration
may be the perfect size to use on the next iteration, for instance when
the initial size is divisible by one of the PMB mapping sizes.

With this patch, we now only need two entries in the PMB to map 256MB of
address space,

	  entry 1: 128MB
	  entry 2: 128MB

Subject: writeback: account IO throttling wait as iowait

It makes sense to do IOWAIT when someone is blocked
due to IO throttle, as suggested by Kame and Peter.

There is an old comment for not doing IOWAIT on throttle,
however it has been mismatching the code for a long time.

If we stop accounting IOWAIT for 2.6.32, it could be an
undesirable behavior change. So restore the io_schedule.

Subject: Btrfs: remove negative dentry when deleting subvolumne

The use of btrfs_dentry_delete is removing dentries from the
dcache when deleting subvolumne. btrfs_dentry_delete ignores
negative dentries. This is incorrect since if we don't remove
the negative dentry, its parent dentry can't be removed.

Subject: lockdep: Use cpu_clock() for lockstat

Some tracepoint magic (TRACE_EVENT(lock_acquired)) relies on
the fact that lock hold times are positive and uses div64 on
that. That triggered a build warning on MIPS, and probably
causes bad output in certain circumstances as well.

Make it truly positive.

Subject: sched: Update the clock of runqueue select_task_rq() selected

In try_to_wake_up(), we update the runqueue clock, but
select_task_rq() may select a different runqueue than the one we
updated, leaving the new runqueue's clock stale for a bit.

This patch cures occasional huge latencies reported by latencytop
when coming out of idle on a mostly idle NO_HZ box.

Subject: Revert "x86, timers: Check for pending timers after (device)
 interrupts"

This reverts commit 9bcbdd9c58617f1301dd4f17c738bb9bc73aca70.

The real bug producing LatencyTop latencies has been fixed in:

  f5dc375: sched: Update the clock of runqueue select_task_rq() selected

And the commit being reverted here triggers local timer processing
from every device IRQ. If device IRQs come in at a high frequency,
this could cause a performance regression.

The commit being reverted here purely 'fixed' the reported latency
as a side effect, because CPUs were being moved out of idle more
often.

Subject: Btrfs: fix file clone ioctl for bookend extents

The file clone ioctl was incorrectly taking the offset into the
extent on disk into account when calculating the length of the
cloned extent.

The length never changes based on the offset into the physical extent.

Test case:

fallocate -l 1g image
mke2fs image
bcp image image2
e2fsck -f image2

(errors on image2)

The math bug ends up wrapping the length of the extent, and things
go wrong from there.

Subject: ALSA: hda - Add full rates/formats support for Nvidia HDMI

Allow Nvidia HDMI to support more possible sample rates and formats.
At best, the really supported rates and formats should be determined
together with the negotiation with the HDMI receiver, but it's currently
not implemented yet (Nvidia stuff seems incompatible with HDMI 1.3
standard in this regard).  As a compromise, we enable all bits, assuming
that all recent devices do support such rates/formats.

Subject: oprofile: fix race condition in event_buffer free

Looking at the 2.6.31-rc9 code, it appears there is a race condition
in the event_buffer cleanup code path (shutdown). This could lead to
kernel panic as some CPUs may be operating on the event buffer AFTER
it has been freed. The attached patch solves the problem and makes
sure CPUs check if the buffer is not NULL before they access it as
some may have been spinning on the mutex while the buffer was being
freed.

The race may happen if the buffer is freed during pending reads. But
it is not clear why there are races in add_event_entry() since all
workqueues or handlers are canceled or flushed before the event buffer
is freed.

Subject: x86/amd-iommu: Workaround for erratum 63

There is an erratum for IOMMU hardware which documents
undefined behavior when forwarding SMI requests from
peripherals and the DTE of that peripheral has a sysmgt
value of 01b. This problem caused weird IO_PAGE_FAULTS in my
case.
This patch implements the suggested workaround for that
erratum into the AMD IOMMU driver.  The erratum is
documented with number 63.

Subject: [IA64] Re-implement spinaphores using ticket lock concepts

Bound the wait time for the ptcg_sem by using similar idea to the
ticket spin locks.  In this case we have only one instance of a
spinaphore, so make it 8 bytes rather than try to squeeze it into
4-bytes to keep the code simpler (and shorter).

Subject: hwmon: (asus_atk0110) Enable the EC

On newer ASUS boards (e.g. P7P55D) the EC (that - among other things - is
responsible for updating the readings from the hwmon sensors) is disabled
by default since ASUS detected conflict with some tools under Windows.
The following patch checks the state of the EC and enable it if needed;
under Linux, native drivers are locked out from ACPI owned resources so
there's no risk of conflict.

Subject: oprofile: warn on freeing event buffer too early

A race shouldn't happen since all workqueues or handlers are canceled
or flushed before the event buffer is freed. A warning is triggered
now if the buffer is freed too early.

Also, this patch adds some comments about event buffer protection,
reworks some code and adds code to clear buffer_pos during alloc and
free of the event buffer.

Subject: IRQ: Change __softirq_pending to unsigned int in
 asm-generic/hardirq.h.

Since the beginnings in aafe4dbed0bf6cbdb2e9f03e1d42f8a540d8541d
("asm-generic: add generic versions of common headers") the generic
version of <asm/hardirq.h> defined __softirq_pending as unsigned long.

Which is different from other architectures for no apparent good reason
and was causing the following warning:

  kernel/time/tick-sched.c: In function 'tick_nohz_stop_sched_tick':
  kernel/time/tick-sched.c:261: warning: format '%02x' expects type 'unsigned int', but argument 2 has type 'long unsigned int'

[ Arnd points out that we really should make sure parisc and alpha are
  ok with this, since they have also been converted to use the generic
  hardirq.h file. But neither seems to use it, although parisc does
  build a IRQSTAT_SIRQ_PEND #define into asm-offsets - but that also
  appears unused..    - Linus ]

Subject: Staging: comedi: serial2002: fix include build issue

Now that sched.h was removed from poll.h, serial2002.c needs
to include it otherwise it does not build properly.

Subject: Staging: remove agnx driver

The agnx driver in the staging tree is broken, does not work, and
development is dead.  The developers have asked for it to be removed
so it now is.

-before 2008 3/1
-
-1: The RX get too much "CRC failed" pakets, it make the card work very unstable,
-2: After running a while, the card will get infinity "RX Frame" and "Error"
-interrupt, not know the root reason so far, try to fix it
-3: Using two tx queue txd and txm but not only txm.
-4: Set the hdr correctly.
-5: Try to do recalibrate correvtly
-6: To support G mode in future
-7: Fix the mac address can't be readed and set correctly in BE machine.
-8: Fix include and exclude FCS in promisous mode and manage mode
-9: Using sta_notify to notice sta change
-10: Turn on frame reception at the end of start
-11: Guess the card support HW_MULTICAST_FILTER
-12: The tx process should be implment atomic?
-13: Using mac80211 function to control the TX&RX LED.

Subject: Staging: remove cowloop driver

The author has found a number of problems with the current version
of this driver in the current kernel, and is reworking it to get
things working again.  Because of that, it would be better to remove
the driver now and add it back in a future kernel release.

-	  Cowloop is a "copy-on-write" pseudo block driver. It can be
-	  stacked on top of a "real" block driver, and catches all write
-	  operations on their way from the file systems layer above to
-	  the real driver below, effectively shielding the lower driver
-	  from those write accesses. The requests are then diverted to
-	  an ordinary file, located somewhere else (configurable). Later
-	  read requests are checked to see whether they can be serviced
-	  by the "real" block driver below, or must be pulled in from
-	  the diverted location. More information and userspace tools to
-	  use the driver are on the project's website

-**       COWLOOP block device driver (2.6 kernel compliant)
-** =======================================================================
-** Read-write loop-driver with copy-on-write functionality.
-**
-** Synopsis:
-**
-**     modprobe cowloop [maxcows=..] [rdofile=..... cowfile=.... [option=r]]
-**
-** Definition of number of configured cowdevices:
-**   maxcows=	number of configured cowdevices (default: 16)
-** (do not confuse this with MAXCOWS: absolute maximum as compiled)
-**
-** One pair of filenames can be supplied during insmod/modprobe to open
-** the first cowdevice:
-**   rdofile=	read-only file (or filesystem)
-**   cowfile=	storage-space for modified blocks of read-only file(system)
-**   option=r	repair cowfile automatically if it appears to be dirty
-**
-** Other cowdevices can be activated via the command "cowdev"
-** whenever the cowloop-driver is loaded.
-**
-** The read-only file may be of type 'regular' or 'block-device'.
-**
-** The cowfile must be of type 'regular'.
-** If an existing regular file is used as cowfile, its contents will be
-** used again for the current read-only file. When the cowfile has not been
-** closed properly during a previous session (i.e. rmmod cowloop), the
-** cowloop-driver refuses to open it unless the parameter "option=r" is
-** specified.
-**
-** Layout of cowfile:
-**
-** 	+-----------------------------+
-**	|       cow head block        |   MAPUNIT bytes
-**	|-----------------------------|
-**	|                             |   MAPUNIT bytes
-**	|---                       ---|
-**	|                             |   MAPUNIT bytes
-**	|---                       ---|
-**	|      used-block bitmap      |   MAPUNIT bytes
-**	|-----------------------------|
-**	|  gap to align start-offset  |
-**	|        to 4K multiple       |
-**	|-----------------------------|  <---- start-offset cow blocks
-**	|                             |
-**      |    written cow blocks       |   MAPUNIT bytes
-**      |          .....              |
-**
-** 	cowhead block:
-**   	  - contains general info about the rdofile which is related
-** 	    to this cowfile
-**
-** 	used-block bitmap:
-** 	  - contains one bit per block with a size of MAPUNIT bytes
-** 	  - bit-value '1' = block has been written on cow
-** 	              '0' = block unused on cow
-** 	  - total bitmap rounded to multiples of MAPUNIT

-**	200507	Check for free space to expand cowfile.	Gerlof Langeveld
-**	200902  Upgrade for kernel 2.6.28               Hendrik-Jan Thomassen
-**
-** Inspired by
-**    loop.c  by Theodore Ts'o and
-**    cloop.c by Paul `Rusty' Russell & Klaus Knopper.
-**
-** Design-considerations:
-**
-**   For the first experiments with the cowloop-driver, the request-queue
-**   made use of the do_generic_file_read() which worked fine except
-**   in combination with the cloop-driver; that combination
-**   resulted in a non-interruptible hangup of the system during
-**   heavy load. Other experiments using the `make_request' interface also
-**   resulted in unpredictable system hangups (with proper use of spinlocks).
-**
-**   To overcome these problems, the cowloop-driver starts a kernel-thread
-**   for every active cowdevice.
-**   All read- and write-request on the read-only file and copy-on-write file
-**   are handled in the context of that thread.
-**   A scheme has been designed to wakeup the kernel-thread as
-**   soon as I/O-requests are available in the request-queue; this thread
-**   handles the requests one-by-one by calling the proper read- or
-**   write-function related to the open read-only file or copy-on-write file.
-**   When all pending requests have been handled, the kernel-thread goes
-**   back to sleep-state.
-**   This approach requires some additional context-switches; however the
-**   performance loss during heavy I/O is less than 3%.

From 4074e77ca3c0c5047acb012a440022ca1f3a2dab Mon Sep 17 00:00:00 2001
From: Pekka Enberg <penberg@cs.helsinki.fi>
Date: Mon, 21 Sep 2009 12:52:15 +0300
Subject: Staging: w35und: Fix ->beacon_int breakage

Commit f424afa17899408cbd267a4c4534ca6fc9d8f71c ("mac80211: remove
deprecated API") removed ->beacon_int from struct ieee80211_conf. Fix
breakage in w35und by setting beacon period in ->add_interface to
bss_conf.beacon_int.

Subject: Staging: winbond: implement prepare_multicast and fix API usage

This patch adds a prepare_multicast callback for the winbond driver
to properly receive mc_count in ->configure_filter.

This also fixes incompatible pointer assignment build errors because
->configure_filter had changed.

This is build tested only, but that's more than the original code received.

Subject: Staging: p9auth: a few fixes

1. The memory into which we copy 'u1@u2' needs space for u1, @,
	u2, and a final \0 which strcat copies in.
2. Strsep changes the value of its first argument.  So use a
	temporary variable to pass to it, so we pass the original
	value to kfree!
3. Allocate an extra char to user_buf, because we need a trailing \0
	since we later kstrdup it.

I am about to send out an LTP testcase for this driver, but
in addition the correctness of the hashing can be verified as
follows:

 #include <stdio.h>
 #include <stdlib.h>
 #include <unistd.h>

int main(int argc, char *argv[])
{
        char in[41], out[20];
        unsigned int v;
        int i, ret;

        ret = read(STDIN_FILENO, in, 40);
        if (ret != 40)
                exit(1);
        in[40] = '\0';
        for (i = 0; i < 20; i++) {
                sscanf(&in[2*i], "%02x", &v);
                out[i] = v;
        }
        write(STDOUT_FILENO, out, 20);
}

as root, to test userid 501 switching to uid 0, choosing
'random' string 'ab':

echo -n "501@0" > plain
openssl sha1  -hmac 'ab' plain |awk '{ print $2 '} > dgst
./unhex < dgst > dgst.u
mknod /dev/caphash 504 0
mknod /dev/capuse 504 1
chmod ugo+w /dev/capuse
cat dgst.u > /dev/caphash

as uid 501,
echo "501@0@ab" > /dev/capuse
id -u  # should now show 0.

Subject: Staging: comedi: s526: fixes for pulse generator

Some changes and corrections to handling of
INSN_CONFIG_GPCT_SINGLE_PULSE_GENERATOR, and
INSN_CONFIG_GPCT_PULSE_TRAIN_GENERATOR, so they interpret insn->data[]
as per the comments in the code.

This should fix the problem of comedi drivers showing up on arches that
can not support the comedi subsystem (like s390).

A follow-up 2.6.32-rc1's

1e384cb0f9a940f2a431d1708f963987e61d71e3
"fujitsu-laptop: support led-class as module"

It's a trivial fix for one of the CONFIG_LEDS_CLASS ifdefs
which was somehow missed in the original patch.

Subject: USB: ftdi_sio: clean up read completion handler

Remove superfluous error checks in completion handler:

 - No need to check private data and urb pointers as we check urb-status
   before dereferencing priv (which is not freed until urb has been killed
   on close).
 - No need to check tty as it is checked again when processing.
 - No need to check urb->number_of_packets on bulk urb.

Note that both private data and tty are checked again before processing
(possibly from work queue which also is cancelled on close).

Subject: USB: ftdi_sio: re-implement read processing

- Re-structure read processing.
 - Kill obsolete work queue and always push to tty in completion handler.
 - Use tty_insert_flip_string instead of per character push when
   possible.
 - Fix stalled-read regression in 2.6.31 by using urb status to
   determine when port is closed rather than port count.
 - Fix race with open/close by checking ASYNCB_INITIALIZED in
   unthrottle.
 - Kill private rx_flag and lock and use throttle flags in
   usb_serial_port instead.

Subject: USB: serial: don't call release without attach

This patch (as1295) fixes a recently-added bug in the USB serial core.
If certain kinds of errors occur during probing, the core may call a
serial driver's release method without previously calling the attach
method.  This causes some drivers (io_ti in particular) to perform an
invalid memory access.

The patch adds a new flag to keep track of whether or not attach has
been called.

Subject: USB: xhci: Handle canceled URBs when HC dies.

When the host controller dies (e.g. it is removed from a PCI card slot),
the xHCI driver cannot expect commands to complete.  The buggy code this
patch fixes would mark an URB as canceled and then expect the URB to be
completed when the stop endpoint command completed.  That would never
happen if the host controller was dead, so the USB core would just hang in
the disconnect code.

If the host controller died, and the driver asks to cancel an URB, free
any structures associated with that URB and immediately give it back.

Subject: USB: xhci: Don't wait for a disable slot cmd when HC dies.

When the host controller dies or is removed while a device is plugged in,
the USB core will attempt to deallocate the struct usb_device.  That will
call into xhci_free_dev().  This function used to attempt to submit a
disable slot command to the host controller and clean up the device
structures when that command returned.  Change xhci_free_dev() to skip the
command submission and just free the memory if the host controller died.

The Blackfin port doesn't support HAVE_CLK and the musb driver works fine
with support stubbed out, so take the existing Blackfin clk stubs and move
them to common musb code so we can drop the Kconfig dependency.

Subject: USB: ipaq: fix oops when device is plugged in

This patch (as1293) fixes a problem with the ipaq serial driver.  It
tries to bind to all the interfaces, even those that don't have enough
endpoints.  The symptom is an invalid memory reference and oops when
the device is plugged in.

Subject: USB: Fix throttling in generic usbserial driver

The generic usbserial driver in Linux 2.6.31 halts its receiving
channel in response to throttle requests from the line discipline.
Unfortunately it drops the contents of the first URB received after
throttling takes effect. This patch corrects that problem.

Subject: USB: storage: When a device returns no sense data, call it a Hardware
 Error

This patch (as1294) fixes a problem that has plagued users for several
kernel releases.  Some USB mass-storage devices don't return any sense
data when they encounter certain kinds of errors.  The SCSI layer
interprets this to mean that the operation should be retried, and the
same thing happens -- over and over again with no limit.  In some
circumstances (such as when a bus reset occurs) that is the right
thing to do, but not here.

The patch checks for this condition (a transport failure with no sense
data) and changes the result code to DID_ERROR and the sense code to
Hardware Error.  This does get only a limited number of retries, and
so the command will fail relatively quickly instead of getting stuck
in an infinite loop.

This fixes a large part of Bugzilla #14118.

Subject: USB: ehci: Fix isoc scheduling boundary checking.

The EHCI driver does some bounds checking when it's scheduling an iTD for
an active endpoint.  It sets the local variable start to
stream->next_uframe and moves that variable further in the schedule if
necessary.  However, the driver fails to do anything with start before
jumping to the ready label and setting the URB's starting frame to
stream->next_uframe.  Alan Stern confirms the EHCI driver should set
stream->next_uframe to start before jumping.

Subject: USB: serial: fix assumption that throttle/unthrottle cannot sleep

many serial subdrivers are clearly written as if throttle/unthrottle
cannot sleep. This leads to unneeded atomic submissions. This
patch converts affected drivers in a way to makes very clear that
throttle/unthrottle can sleep. Thus future misdesigns can be avoided
and efficiency and reliability improved.

This removes any such assumption using GFP_KERNEL and spin_lock_irq()

visor_unthrottle() mustn't resubmit the URB unconditionally
as the URB may still be running.

the same bug as opticon.

Subject: ALSA: ice1724: Fix surround on Chaintech AV-710

Fix the num_total_dacs setting for Chaintech AV710. The existing comment
that only PSDOUT0 is connected is correct, but since the card is using
packed AC97 mode to send 6 channels to the codec, num_total_dacs should be
set to 6 and not 2. This allows 6-channel surround to work. Also clarify
a comment regarding the additional WM8728 codec on this card (it's connected
to the SPDIF output and always receives the same data).

Subject: ARM: 5754/1: ep93xx: update i2c support

Update the ep93xx i2c support:

  1) The platform init code passes the configuration data for the
     i2c-gpio driver.  This allows any gpio pin do be used for the
     sda and scl pins.  It also allows the platform to specify the
     udelay and timeout.
  2) Program the gpio configuration register to enable/disable the
     open drain drivers.  Note that this really only works if the
     sda and scl pins are set to EP93XX_GPIO_LINE_EEDAT and
     EP93XX_GPIO_LINE_EECLK.
  3) Update the edb93xx.c platform init to use the new support.

From ebd00c08e28a0ab4dcb715d222214625fff6d62a Mon Sep 17 00:00:00 2001
From: Hartley Sweeten <hartleys@visionengravers.com>
Date: Thu, 8 Oct 2009 23:44:41 +0100
Subject: ARM: 5756/1: ep93xx: introduce clk parent

The clock generation system in the ep93xx uses two external oscillator's
and two internal PLLs to derive all the internal clocks.  Many of these
internal clocks can be stopped to save power.

This introduces a "parent" hierarchy for the clocks so that the users
count can be correctly tracked for power management.

The "parent" for the video clock can either be one of the PLL outputs
or the external oscillator.  In order to correctly track the "parent"
for the video clock calc_clk_div() needed to be modified.  It now
returns an error code if the desired rate cannot be generated.

Subject: ARM: Dump memory and backtrace as one printk per line

dump_mem and dump_backtrace were both using multiple printk statements
to print each line.  With DEBUG_LL enabled, this causes OOPS to become
very difficult to read.  Solve this by only using one printk per line.

Subject: ARM: boolean bit testing

Bit testing (test, testset, testclear, testchange) for bit numbers
known at compile time returns a word with the tested-for bit set.

Change it to return a true boolean value so to make it consistent with
the out-of-line path and all the other bitops implementations.

After m68k's task_thread_info() doesn't refer to current,
it's possible to remove sched.h from interrupt.h and not break m68k!
Many thanks to Heiko Carstens for allowing this.

Subject: ROMFS: fix length used with romfs_dev_strnlen() function

An interestingly corrupted romfs file system exposed a problem with the
romfs_dev_strnlen function: it's passing the wrong value to its helpers.
Rather than limit the string to the length passed in by the callers, it
uses the size of the device as the limit.

Subject: kbuild: fix the binrpm-pkg target to work with KBUILD_OUTPUT set

The binrpm-pkg target (binary RPM only) fails when called with
KBUILD_OUTPUT set. This patch makes it work.

For the rpm-pkg target (source + binary RPM), building with
KBUILD_OUTPUT set is not possible and also not needed as the
actual build is done in a temporary directory anyway, so check
that KBUILD_OUTPUT is not set in that case to avoid later errors.

Alek reported that on Ubuntu, where dash is used, 'echo -e'
can't work, so let's use non-builtin echo in this case.

Subject: kbuild: Fix size_append issue for bzip2/lzma kernel

The Makefile.lib will call "echo -ne" to append uncompressed kernel size to
bzip2/lzma kernel image.
The "echo" here depends on the shell that /bin/sh pointing to.
On Ubuntu system, the /bin/sh is pointing to dash, which does not support
"echo -e" at all. Use /bin/echo instead of shell echo should always be safe.

User applications frequently hit problems when they try to use
the kernel headers directly, rather than the exported headers.

This adds an explicit warning for this case, and points to
a URL holding an explanation of why this is wrong and what
to do about it.

Subject: kbuild: revert "save ARCH & CROSS_COMPILE ..."

Revert commit 575543347b5baed0ca927cb90ba8807396fe9cc9

It caused following issues:

- On architectures where ARCH= setting is used to select between
  32 and 64 bit this was no longer possible without "make mrproper"
- If ARCH was changed then kbuild refused to run "make mrproper"
  because ARCH had changed
- When CROSS_COMPILE was changed people were asked to run "make mrproper"
  but kbuild refused to run "make mrproper" because CROSS_COMPILE changed.
- Spaces in CROSS_COMPILE was not 'supported'
- If an non-existing ARCH= was used kbuild could get stuck

Lessons learned:
. Despite being simple and straghtforward people uses very different
  approaches when building the kernel.

. CROSS_COMPILE is sometimes used for ccache despite cache being
  only a CC frontend so one would have expected CC to be
  used for this purpose.

. And obviously this was not tested widely enough.

Subject: pci: increase alignment to make more space for hidden code

As reported in

	http://bugzilla.kernel.org/show_bug.cgi?id=13940

on some system when acpi are enabled, acpi clears some BAR for some
devices without reason, and kernel will need to allocate devices for
them.  It then apparently hits some undocumented resource conflict,
resulting in non-working devices.

Try to increase alignment to get more safe range for unassigned devices.

Subject: Revert "USB: Work around BIOS bugs by quiescing USB controllers
 earlier"

This reverts commit db8be50c4307dac2b37305fc59c8dc0f978d09ea, as per

	http://bugzilla.kernel.org/show_bug.cgi?id=14374
	http://marc.info/?l=linux-kernel&m=125446885705223&w=4

We simply can't do the USB handoff at FIXUP_HEADER time, since it will
often require us to have valid IO mappings etc.  But that in turn
requires a whole different approach, not this trivial one-liner.

Maybe we could teach all the USB quirk handoff handlers to only do the
quirk if the device has all its registers set up (since if it isn't
initialized, it's unlikely to be active), but regardless that will need
a whole lot more code than just saying "let's do it really early".

The proper fix is almost certainly to just leave the legacy IOMMU
mappings active until after all devices have been initialized.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

The hook may change the number of bytes per pixel being scanned out, which
affects the CRTC memory bandwidth requirements. E.g. booting in 8bpp and then
running X in 32bpp would result in the bandwidth requirements being
underestimated for the latter and consequently in CRTC FIFO underruns causing
visible artifacts with 3D intensive workloads.

ATOM changes only compile-tested.

Subject: drm/radeon/kms: Fix apparent typo in legacy CRTC memory bandwidth
 calculation.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

While investigating the cause of CRTC FIFO underruns, I noticed that when
converting the memory bandwidth calculation from the userspace X driver code,
an instance of '8.0' was apparently accidentally converted to '80'.

Subject: drm/radeon/kms: make sure LVDS panel is valid in detect()

If the panel data is bogus this can lead to problems
later when the hardware trys to set the mode.  If the
data is invalid, report LVDS as disconnected.

Should fix fdo bug 24247.

From de2103e452ec7f2db5db7c44279735688608381d Mon Sep 17 00:00:00 2001
From: Alex Deucher <alexdeucher@gmail.com>

Subject: drm/radeon/kms: use drm_mode directly for panel modes

This reduces the number of mode format conversions needed
and makes native panel mode support cleaner.

Subject: drm/radeon: Revert "drm/r600: avoid assigning vb twice in blit code"

This reverts commit 49c458e544ae14514209ed80ea6829ca1b18ddf0. It
seems to have some side effects in the non-kms cases.

This probably deserves to go into -stable.

Pedit will reject a policy that is large because it
uses the wrong structure in the policy validation.

Subject: net: Fix struct sock bitfield annotation

Since commit a98b65a3 (net: annotate struct sock bitfield), we lost
8 bytes in struct sock on 64bit arches because of
kmemcheck_bitfield_end(flags) misplacement.

Fix this by putting together sk_shutdown, sk_no_check, sk_userlocks,
sk_protocol and sk_type in the 'flags' 32bits bitfield

Subject: perf tools: Fix const char type propagation

The following perf build warnings/errors in function
argument types:

  builtin-sched.c:1894: warning: passing argument 1 of 'sort_dimension__add' discards qualifiers from pointer target type
  util/trace-event-parse.c:685: warning: passing argument 2 of 'read_expected' discards qualifiers from pointer target type

  util/trace-event-parse.c:706: warning: passing argument 2 of 'read_expected_item' discards qualifiers from pointer target type

... trigger because older GCC is not able to prove that
sort_dimension__add() does not change the string.

Some goes for test_type_token().

Fix this by improving type consistency.

Currently the irq_type field of the csb726_lan_config structure is

SMSC911X_IRQ_POLARITY_ACTIVE_LOW, is normally stored in the irq_polarity
field, so I have renamed the field in the first initialization to that.

Subject: perf tools: Fix the NO_64BIT build on pure 64-bit systems

Randy Dunlap reported that 'make NO_64BIT=1' fails to build
a pure 32-b it binary on 64-bit/64-bit x86 systems.

The reason is that we dont pass in the -m32 and GCC defaults
to -m64.

So pass it in - and also extend the warning message about libelf
dependencies - glibc-dev[el] is needed as well beyond the libelf
library.

Subject: sparc64: Fix D-cache flushing on swapin from SW devices.

Thanks to tip form ARM folks and Russell King.

If flush_dcache_page() occurs on a swapin it will have a mapping
and we'll try to defer the flush by setting the dirty bit.

But when it hits update_dcache_page() we won't flush because the
page won't have a mapping any more.  So remove the mapping
requirement in flush_dcache().

The usb regulator supplies (usb1v5, usb1v8 & usb3v1) must be available
before adding the twl4030_usb child, else twl4030_usb_ldo_init() will
always fail thus causing boot lock-up.

Subject: Run pci_apply_final_quirks() sooner.

Having this as a device_initcall() means that some real device drivers
can actually initialise _before_ the quirks are run, which is wrong.

We want it to run _before_ device_initcall(), but _after_ fs_initcall(),
since some arch-specific PCI initialisation like pcibios_assign_resources()
is done at fs_initcall().

We could use rootfs_initcall() but I actually want to use that for the
IOMMU initialisation, which has to come after the quirks, but still
before the real devices. So use fs_initcall_sync() instead -- since this
is entirely synchronous, it doesn't hurt that it'll escape the
synchronisation.

We want this to happen after the PCI quirks, which are now running at

This works around the BIOS problems which were originally addressed by
commit db8be50c4307dac2b37305fc59c8dc0f978d09ea ('USB: Work around BIOS
bugs by quiescing USB controllers earlier'), which was reverted in

Subject: ARM: force dcache flush if dcache_dirty bit set

On ARM, update_mmu_cache() does dcache flush for a page only if
it has a kernel mapping (page_mapping(page) != NULL). The correct
behavior would be to force the flush based on dcache_dirty bit only.

One of the cases where present logic would be a problem is when
a RAM based block device[1] is used as a swap disk. In this case,
we would have in-memory data corruption as shown in steps below:

do_swap_page()
{
    - Allocate a new page (if not already in swap cache)
    - Issue read from swap disk
        - Block driver issues flush_dcache_page()
        - flush_dcache_page() simply sets PG_dcache_dirty bit and does not
          actually issue a flush since this page has no user space mapping yet.
    - Now, if swap disk is almost full, this newly read page is removed
      from swap cache and corrsponding swap slot is freed.
    - Map this page anonymously in user space.
    - update_mmu_cache()
        - Since this page does not have kernel mapping (its not in page/swap
          cache and is mapped anonymously), it does not issue dcache flush
          even if dcache_dirty bit is set by flush_dcache_page() above.

    <user now gets stale data since dcache was never flushed>
}

Same problem exists on mips too.

[1] example:
 - brd (RAM based block device)
 - ramzswap (RAM based compressed swap device)

Subject: mac80211: fix ibss race

When a scan completes, we call ieee80211_sta_find_ibss(),
which is also called from other places. When the scan was
done in software, there's no problem as both run from the
single-threaded mac80211 workqueue and are thus serialised
against each other, but with hardware scan the completion
can be in a different context and race against callers of
this function from the workqueue (e.g. due to beacon RX).
So instead of calling ieee80211_sta_find_ibss() directly,
just arm the timer and have it fire, scheduling the work,
which will invoke ieee80211_sta_find_ibss() (if that is
appropriate in the current state).

Subject: mac80211: document ieee80211_rx() context requirement

ieee80211_rx() must be called with softirqs disabled
since the networking stack requires this for netif_rx()
and some code in mac80211 can assume that it can not
be processing its own tasklet and this call at the same
time.

It may be possible to remove this requirement after a
careful audit of mac80211 and doing any needed locking
improvements in it along with disabling softirqs around
netif_rx(). An alternative might be to push all packet
processing to process context in mac80211, instead of
to the tasklet, and add other synchronisation.

Subject: USB: musb: invert arch depend string

The MUSB code relies on platform implementations that currently only
exists for Arm and Blackfin processors, so have the MUSB Kconfig depend
upon those arches.

This should prevent other arches from building MUSB via randconfig.

Subject: ext3: Don't update superblock write time when filesystem is read-only

This avoids updating the superblock write time when we are mounting
the root file system read/only but we need to replay the journal; at
that point, for people who are east of GMT and who make their clock
tick in localtime for Windows bug-for-bug compatibility, and this will
cause e2fsck to complain and force a full file system check.

Subject: sh: force dcache flush if dcache_dirty bit set.

This too follows the ARM change, given that the issue at hand applies to
all platforms that implement lazy D-cache writeback.

This fixes up the case when a page mapping disappears between the
flush_dcache_page() call (when PG_dcache_dirty is set for the page) and
the update_mmu_cache() call -- such as in the case of swap cache being
freed early. This kills off the mapping test in update_mmu_cache() and
switches to simply testing for PG_dcache_dirty.

Subject: ACPI / PCI: Fix NULL pointer dereference in acpi_get_pci_dev() (rev.
 2)

acpi_get_pci_dev() may be called for a non-PCI device, in which case
it should return NULL.  However, it assumes that every handle it
finds in the ACPI CA name space, between given device handle and the
PCI root bridge handle, corresponds to a PCI-to-PCI bridge with an
existing secondary bus.  For this reason, when it finds a struct
pci_dev object corresponding to one of them, it doesn't check if
its 'subordinate' field is a valid pointer.  This obviously leads to
a NULL pointer dereference if acpi_get_pci_dev() is called for a
non-PCI device with a PCI parent which is not a bridge.

To fix this issue make acpi_get_pci_dev() check if pdev->subordinate
is not NULL for every device it finds on the path between the root
bridge and the device it's supposed to get to and return NULL if the
"target" device cannot be found.

Subject: eeepc-laptop: Properly annote eeepc_enable_camera().

Currently the annotation for function eeepc_enable_camera() is
__init, and refers to a
function eeepc_hotk_add() which is non-init. Use __devinit for both
functions which is
more appropriate and fixes a section mismatch warning.

 We were warned by the following warning:

  LD      drivers/platform/x86/built-in.o
WARNING: drivers/platform/x86/built-in.o(.text+0x12e1): Section
mismatch in reference from the function eeepc_hotk_add() to the
function .init.text:eeepc_enable_camera()
The function eeepc_hotk_add() references
the function __init eeepc_enable_camera().
This is often because eeepc_hotk_add lacks a __init
annotation or the annotation of eeepc_enable_camera is wrong.

triggered when the hardware "disappears" from beneath the driver, i.e. when
wireless is toggled off via ACPI. It does so by ensuring that the rfkill
soft-block flag is set before the hardware is disabled.

I do not know whether this patch is required if rt2800pci is in use instead
of rt2860sta; at the time of submission of this patch, I've not been able to
test this.

Subject: ACPI: video: Loosen strictness of video bus detection code

BugLink: http://bugs.launchpad.net/bugs/333386

Currently a video bus device must (beside other criteria) define _DOD and
_DOS methods to be considered a video device.
Some broken BIOSes prevented working backlight control by only defining both
for one (non-existing bus) and only _DOD for the rest. With this patch in
place the other bus definitions were considered too and backlight control
started to work again.

The IXP 2000 network driver was failing to build as it has its own
statistics gathering which was not compatible with the recent network
device operations changes. This patch fixes the driver in the obvious
way and has been compile tested. I have been unable to get the ixp2000
maintainer to comment or test this fix.

fails, it already does any necessary call to pci_release_regions,
so this does not need to be done again in cciss_init_one in that
case.

Subject: cciss: Add cciss_allow_hpsa module parameter

Add cciss_allow_hpsa module parameter.  This parameter causes
the cciss driver to ignore any Smart Array devices known to be
supported by the hpsa driver.

Subject: x86/paravirt: Use normal calling sequences for irq enable/disable

Bastian Blank reported a boot crash with stackprotector enabled,
and debugged it back to edx register corruption.

For historical reasons irq enable/disable/save/restore had special
calling sequences to make them more efficient.  With the more
recent introduction of higher-level and more general optimisations
this is no longer necessary so we can just use the normal PVOP_
macros.

This fixes some residual bugs in the old implementations which left
edx liable to inadvertent clobbering. Also, fix some bugs in
__PVOP_VCALLEESAVE which were revealed by actual use.

Subject: pcm970 mmc: Fix ro switch

We have to use mxc_gpio_mode() for the card detection pin
instead of mxc_gpio_setup_multiple_pins() because the latter
does a gpio_request() and thus a later gpio_request() fails.

Subject: tcp: fix tcp_defer_accept to consider the timeout

I was trying to use TCP_DEFER_ACCEPT and noticed that if the
client does not talk, the connection is never accepted and
remains in SYN_RECV state until the retransmits expire, where
it finally is deleted. This is bad when some firewall such as
netfilter sits between the client and the server because the
firewall sees the connection in ESTABLISHED state while the
server will finally silently drop it without sending an RST.

This behaviour contradicts the man page which says it should
wait only for some time :

       TCP_DEFER_ACCEPT (since Linux 2.4)
          Allows a listener to be awakened only when data arrives
          on the socket.  Takes an integer value  (seconds), this
          can  bound  the  maximum  number  of attempts TCP will
          make to complete the connection. This option should not
          be used in code intended to be portable.

Also, looking at ipv4/tcp.c, a retransmit counter is correctly
computed :

        case TCP_DEFER_ACCEPT:
                icsk->icsk_accept_queue.rskq_defer_accept = 0;
                if (val > 0) {
                        /* Translate value in seconds to number of
                         * retransmits */
                        while (icsk->icsk_accept_queue.rskq_defer_accept < 32 &&
                               val > ((TCP_TIMEOUT_INIT / HZ) <<
                                       icsk->icsk_accept_queue.rskq_defer_accept))
                                icsk->icsk_accept_queue.rskq_defer_accept++;
                        icsk->icsk_accept_queue.rskq_defer_accept++;
                }
                break;

==> rskq_defer_accept is used as a counter of retransmits.

But in tcp_minisocks.c, this counter is only checked. And in
fact, I have found no location which updates it. So I think
that what was intended was to decrease it in tcp_minisocks
whenever it is checked, which the trivial patch below does.

Subject: WAN: fix Cisco HDLC handshaking.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Cisco HDLC uses keepalive packets and sequence numbers to determine link
state. In rare cases both ends could transmit keepalive packets at the same
time, causing the received sequence numbers to be treated as incorrect.
Now we accept our current sequence number as well as the previous one.

Subject: udp: Fix udp_poll() and ioctl()

udp_poll() can in some circumstances drop frames with incorrect checksums.

Problem is we now have to lock the socket while dropping frames, or risk
sk_forward corruption.

This bug is present since commit 95766fff6b9a78d1
([UDP]: Add memory accounting.)

While we are at it, we can correct ioctl(SIOCINQ) to also drop bad frames.

Access to damp_power_widgets() is assumed to be single-threaded.
Concurrent accesses to dapm_power_widgets() may result in
unpredictable behavior.

Calls from:
close_delayed_work()
soc_codec_close()
soc_pcm_prepare()
soc_suspend()
soc_resume_deferred()
to snd_soc_dapm_stream_event() do not have the codec->mutex
taken to cover the call to dapm_power_widgets(). Thus, take
the mutex in these paths also to assure single-threaded use
of dapm_power_widgets().

Subject: ALSA: hda - Fix mute sound with STAC9227/9228 codecs

On FSC laptops, the sound gets muted gradually when the volume is chnaged.
This is due to the wrong volume-knob widget setup.  The delta bit (bit 7)
shouldn't be set for these devices.

This patch adds a new quirk to set the value 0x7f to the widget 0x24
instead of 0xff.

Subject: ALSA: aaci: ARM1176 aaci-pl041 AC97 register read timeout

After a reboot on an ARM1176 which amounts to a softreset, it has been
noted that the ALSA driver does not get registered and the probe fails
with the error "aaci-pl041 fpga:04: ac97 read back fail". In the process
of reading from a register the SL1TxBusy bit is set indicating that the
transceiver is busy and remains so until the default timeout occurs.
Set the Power down register 0x26 to an arbitrary value as specified in
the PL041 manual (page: 3-18) so that AACISL1TX/AACISL2TX registers take
their default state.

Subject: [SCSI] fix memory leak in initialization

The root cause of the problem is the fact that dev_set_name() now
allocates storage instead of using the original array within the kobj.
That means that the SCSI assumption that if you haven't made the
containing object or any sub objects visible, you can just destroy it
(and its component devices) lock stock and barrel becomes false.

Fix this by doing the get of sdev_dev at parent time and thus do an
extra put of it in scsi_destroy_sdev() (and all other destruction
without add paths).

Subject: drm/i915: Set the LVDS_BORDER when using LVDS scaling mode

According to the spec the LVDS_BORDER_ENABLE bit decides whether the border
data should be included in the active display and data sent to the panel.
Border should be used when in VGA centered (un-scaled) mode or when scaling
a 4:3 source image to a wide screen panel (typical 16:9).

So when the LVDS scaling is used, decide whether the LVDS_BORDER should be
enabled or not according to the current scaling mode.

At the same time fix the typo error in LVDS center scaling mode.

Subject: Btrfs: only write one super copy during fsync

During a tree-log commit for fsync, we've been writing at least
two copies of the super block and forcing them to disk.

The other filesystems write only one, and this change brings us on
par with them.  A full transaction commit will write all the super
copies, so we still have redundant info written on a regular
basis.

Subject: Btrfs: avoid tree log commit when there are no changes

rpm has a habit of running fdatasync when the file hasn't
changed.  We already detect if a file hasn't been changed
in the current transaction but it might have been sent to
the tree-log in this transaction and not changed since
the last call to fsync.

In this case, we want to avoid a tree log sync, which includes
a number of synchronous writes and barriers.  This commit
extends the existing tracking of the last transaction to change
a file to also track the last sub-transaction.

The end result is that rpm -ivh and -Uvh are roughly twice as fast,
and on par with ext3.

Subject: Btrfs: streamline tree-log btree block writeout

Syncing the tree log is a 3 phase operation.

1) write and wait for all the tree log blocks for a given root.

2) write and wait for all the tree log blocks for the
tree of tree log roots.

3) write and wait for the super blocks (barriers here)

This isn't as efficient as it could be because there is
no requirement to wait for the blocks from step one to hit the disk
before we start writing the blocks from step two.  This commit
changes the sequence so that we don't start waiting until
all the tree blocks from both steps one and two have been sent
to disk.

We do this by breaking up btrfs_write_wait_marked_extents into
two functions, which is trivial because it was already broken
up into two parts.

Subject: [IA64] Restore registers in the stack on INIT

Registers are not saved anywhere when INIT comes during fsys mode and
we cannot know what happened when we investigate vmcore captured by
kdump. This patch adds new function finish_pt_regs() so registers can
be saved in such a case.

Subject: [IA64] Require SAL 3.2 in order to do extended config space ops

We had assumed that SAL firmware would return an error if it didn't
understand extended config space.  Unfortunately, the SAL on the SGI 750
doesn't do that, it panics the machine.  So, condition the extended PCI
config space accesses on SAL revision 3.2.

Subject: drm/i915: Fix FDI M/N setting according with correct color depth

FDI M/N calculation hasn't taken the current pipe color depth into account,
but always set as 24bpp. This one checks current pipe color depth setting,
and change FDI M/N calculation a little to use bits_per_pixel first, then
convert to bytes_per_pixel later.

This fixes display corrupt issue on Arrandle LVDS with 1600x900 panel
in 18bpp dual-channel mode.

While the input core indeed takes care of restoring led state and
typematic settings upon resume the driver still need to initialize
them properly when registering a new device

Subject: xfs: fix double IRELE in xfs_dqrele_inode

xfs_dqrele_inode calls xfs_iput to release the ilock and a reference
and then also calls IRELE which does a second decrement of the reference
count.  This leads to a premature freeing of inodes when quotas were turned
off while the filesystem was mounted.

Thanks to Utako Kusaka for reporting the bug and provinding a good testcase.

Subject: futex: Handle spurious wake up

The futex code does not handle spurious wake up in futex_wait and
futex_wait_requeue_pi.

The code assumes that any wake up which was not caused by futex_wake /
requeue or by a timeout was caused by a signal wake up and returns one
of the syscall restart error codes.

In case of a spurious wake up the signal delivery code which deals
with the restart error codes is not invoked and we return that error
code to user space. That causes applications which actually check the
return codes to fail. Blaise reported that on preempt-rt a python test
program run into a exception trap. -rt exposed that due to a built in
spurious wake up accelerator :)

Solve this by checking signal_pending(current) in the wake up path and
handle the spurious wake up case w/o returning to user space.

Subject: TI DaVinci EMAC: Clear statistics register properly.

The mechanism to clear the statistics register is dependent
on the status of GMIIEN bit in MAC control register. If the
GMIIEN bit is set, the stats registers are write to decrement.
If the GMIIEN bit is cleared, the stats registers are plain
read/write registers. The stats register clearing operation
must take into account the current state of GMIIEN as it
can be cleared when the interface is brought down.

With existing implementation logic, querying for interface stats
when the interface is down, can corrupt the statistics counters.
This patch examines the GMIIEN bit status in MAC_CONTROL
register before choosing an appropriate mask for clearing stats
registers.

Subject: powerpc/ftrace: show real return addresses in modules

When the function graph tracer is enabled, it replaces the return address
with a hook back to the tracer. This makes back traces see the hook instead
of the actual return address.

The current code also shows the real address by checking if the return
address jumps to the return_to_handler. If it is, is also prints out
the saved real return address.

On powerpc64, some modules may return to mod_return_to_handler, which
is not checked. This patch will also show the real address if a return
is to mod_return_to_handler as well.

Subject: powerpc64/ftrace: use PACA to retrieve TOC in mod_return_to_handler

The mod_return_to_handler needs to switch to the kernel TOC before
jumping to a the kernel code. It currently does this by looking
at the kernel function data and retrieves the TOC that way.

Not only is this inefficient, it also breaks with a relocatable kernel.
The PACA contains the kernel TOC and we can easily retrieve it that
way.

Subject: powerpc/pmac: Fix issues with sleep on some powerbooks

Since the change of how interrupts are disabled during suspend,
certain PowerBook models started exhibiting various issues during
suspend or resume from sleep.

I finally tracked it down to the code that runs various "platform"
functions (kind of little scripts extracted from the device-tree),
which uses our i2c and PMU drivers expecting interrutps to work,
and at a time where with the new scheme, they have been disabled.

This causes timeouts internally which for some reason results in
the PMU being unable to see the trackpad, among other issues, really
it depends on the machine. Most of the time, we fail to properly adjust
some clocks for suspend/resume so the results are not always
predictable.

This patch fixes it by using IRQF_TIMER for both the PMU and the I2C
interrupts. I prefer doing it this way than moving the call sites since
I really want those platform functions to still be called after all
drivers (and before sysdevs).

We also do a slight cleanup to via-pmu.c driver to make sure the
ADB autopoll mask is handled correctly when doing bus resets

On pSeries, we always force the IO space to be mapped using 4K
pages even with a 64K base page size to cope with some limitations
in the HV interface to some devices.

However, the SLB miss handler code to discriminate between vmalloc
and ioremap space uses a CPU feature section such that the code
is nop'ed out when the processor support large pages non-cachable
mappings.

Thus, we end up always using the ioremap page size for vmalloc
segments on such processors, causing a discrepency between the
segment and the hash table, and thus a hang continously hashing
the page.

It works for the first segment of the vmalloc space since that
segment is "bolted" in by C code correctly, and thankfully we
almost never use the vmalloc space beyond the first segment,
but the new percpu code made the bug happen.

This fixes it by removing the feature section from the assembly,
we now always do the comparison between vmalloc and ioremap.

Subject: powerpc: Fix hypervisor TLB batching

Profiling of a page fault scalability microbenchmark shows flush_hash_range
is not calling the batch hpte invalidate hcall (H_BULK_REMOVE).

It turns out we have a duplicate firmware feature for hcall-bulk and the
current setup code stops after finding the first match. This meant we never
batch and always do individual invalidates.

The patch below removes the duplicate and shifts FW_FEATURE_CMO to close
the gap. With the patch applied the single threaded page fault rate improves
from 217169 to 238755 per second on a POWER5 test box, a 10% improvement.

We need to align before the output section. Having the align inside
the output section causes the linker to put some filler in there,
which makes it a non-empty section, but this section isn't assigned to
a segment so you get a warning from the linker.

making a powerpc target with PCI support, shows the

function pcibios_allocate_bus_resources() to the function .init.text:reparent_resources()

The function pcibios_allocate_bus_resources() references
the function __init reparent_resources().

This is often because pcibios_allocate_bus_resources lacks a __init
annotation or the annotation of reparent_resources is wrong.

This patch fix this warning by removing the __init
annotation before reparent_resources.

Subject: perf_event: Adjust frequency and unthrottle for non-group-leader
 events

The loop in perf_ctx_adjust_freq checks the frequency of sampling
event counters, and adjusts the event interval and unthrottles the
event if required, and resets the interrupt count for the event.
However, at present it only looks at group leaders.

This means that a sampling event that is not a group leader will
eventually get throttled, once its interrupt count reaches
sysctl_perf_event_sample_rate/HZ --- and that is guaranteed to
happen, if the event is active for long enough, since the interrupt
count never gets reset.  Once it is throttled it never gets
unthrottled, so it basically just stops working at that point.

This fixes it by making perf_ctx_adjust_freq use ctx->event_list
rather than ctx->group_list.  The existing spin_lock/spin_unlock
around the loop makes it unnecessary to put rcu_read_lock/
rcu_read_unlock around the list_for_each_entry_rcu().

Subject: Input: atkbd - postpone restoring LED/repeat rate at resume

We need to postpone restoring LED state and typematic settings until
keyboard is finished reconnecting upon resume. Normally driver core
and PM infrastructure takes care of proper ordering and dependencies,
but or case actual reconnect is done asynchronously from kseriod.
So while driver core thinks that keyboard was resumed and it is time
to let input core run it's resume handlers in reality keyboard is not
ready yet. The solution is to keep rescheduling work that adjusts LED
and rate settings until keyboard is fully enabled.

Subject: Input: fix locking issue in /proc/bus/input/ handlers

input_devices_seq_start() uses mutex_lock_interruptible() to acquire
the input_mutex, but doesn't properly handle the situation when the
call fails (for example due to interrupt). Instead of returning NULL
(which indicates that there is no more data) we should return
ERR_PTR()-encoded error.

We also need explicit flag indicating whether input_mutex was acquired
since input_devices_seq_stop() is called whether input_devices_seq_start()
was successful or not.

The same applies to input_handlers_seq_start().

After sucessfully registering the misc device the driver iounmaps the
hardware registers and kfree's the device data structure. Ouch !

This was introduced with commit e42311d75 (riowatchdog: Convert to

Return success instead of dropping into the error cleanup code path.

The 32-bit wide variant of "mov pc, reg" in Thumb-2 is unpredictable
causing improper handling of the undefined instructions not caught by
the kernel. This patch adds a movw_pc macro for such situations
(currently only used in call_fpe).

Subject: [S390] tape390: Fix request queue handling in block driver

When setting a channel attached tape online under Linux 2.6.31, the

"vol_id" process from udev hangs in sync_page():
 2 sync_page+144 [0x1dfaac]
 3 __wait_on_bit_lock+194 [0x58c23e]
 4 __lock_page+116 [0x1df9dc]
 5 truncate_inode_pages_range+728 [0x1ed7cc]
 6 __blkdev_put+244 [0x25f738]
 7 __fput+300 [0x229c4c]
 8 filp_close+122 [0x225a3a]

The reason for that is an error in the request queue handling. It can
happen that we fetch a request, but do not process it further because
the number of queued requests exceeds TAPEBLOCK_MIN_REQUEUE.
To fix this, we should call blk_peek_request() instead of
blk_fetch_request() in the while condition and fetch the request in
the loop body afterwards.

This bug was introduced with the patch "block: implement and enforce
request peek/start/fetch" (9934c8c04561413609d2bc38c6b9f268cba774a4)

Subject: [S390] cio: change misleading console logic

Use cio_is_console() in io_subchannel_probe to indicate that the
special handling is console specific. As long as there is no other
subchannel for which this might be true, it is misleading to speak
of "early devices". Should more of these devices be introduced,
a cleanup of all console special handling is in order anyway.

So disable it in order to promote spreading outside of the cache
domains.

Subject: sched: Do less agressive buddy clearing

Yanmin reported a hackbench regression due to:

 > commit de69a80be32445b0a71e8e3b757e584d7beb90f7
 > Author: Peter Zijlstra <a.p.zijlstra@chello.nl>

 >
 >     sched: Stop buddies from hogging the system

I really liked de69a80b, and it affecting hackbench shows I wasn't
crazy ;-)

So hackbench is a multi-cast, with one sender spraying multiple
receivers, who in their turn don't spray back.

This would be exactly the scenario that patch 'cures'. Previously
we would not clear the last buddy after running the next task,
allowing the sender to get back to work sooner than it otherwise
ought to have been, increasing latencies for other tasks.

Now, since those receivers don't poke back, they don't enforce the
buddy relation, which means there's nothing to re-elect the sender.

Cure this by less agressively clearing the buddy stats. Only clear
buddies when they were not chosen. It should still avoid a buddy
sticking around long after its served its time.

There's a problem where we don't do any space reservation for truncates, which
can cause you to OOPs because you will be allowed to go off in the weeds a bit
since we don't account for the delalloc bytes that are created as a result of
the truncate.

Subject: Btrfs: properly wait log writers during log sync

A recently fsync optimization make btrfs_sync_log skip calling
wait_for_writer in the single log writer case. This is incorrect
since the writer count can also be increased by btrfs_pin_log.

Subject: Btrfs: always pin metadata in discard mode

We have an optimization in btrfs to allow blocks to be
immediately freed if they were allocated in this transaction and never
written.  Otherwise they are pinned and freed when the transaction
commits.

This isn't optimal for discard mode because immediately freeing
them means immediately discarding them.  It is better to give the
block to the pinning code and letting the (slow) discard happen later.

Subject: omap: RX-51: Drop I2C-1 speed to 2200

The I2C-1 bus frequency on RX-51 should be 2.2 MHz. The speed is limited
by TWL5030/GAIA; a higher speed could lead to errors on the interface. The
maximum speed depends on the system clock for GAIA: 2.2 MHz (if 19.2 MHz),
2.4 MHz (26 MHz) or 2.9 MHz (38.4 MHz).

Subject: firewire: sbp2: provide fallback if mgt_ORB_timeout is missing

The Unit_Characteristics entry of an SBP-2 unit directory is not
mandatory as far as I can tell.  If it is missing, we would probably
fail to log in into the target because firewire-sbp2 would not wait for
status after it sent the login request.

The fix moves the cleanup of tgt->mgt_orb_timeout into a place where it
is executed exactly once before login, rather than 0..n times depending
on the target's config ROM.  With targets with one or more
Unit_Characteristics entries, the result is the same as before.

Subject: futex: Check for NULL keys in match_futex

If userspace tries to perform a requeue_pi on a non-requeue_pi waiter,
it will find the futex_q->requeue_pi_key to be NULL and OOPS.

Check for NULL in match_futex() instead of doing explicit NULL pointer
checks on all call sites.  While match_futex(NULL, NULL) returning
false is a little odd, it's still correct as we expect valid key
references.

Subject: USB: whci-hcd: handle early deletion of endpoints

If an endpoint is deleted before it's been fully added to the hardware
list, the associated qset will not be fully initialized and an oops will
occur when complete(&qset->remove_complete) is called.  This can happen
if a queued URB is cancelled.

Fix this by only removing the qset from the hardware list if the
cancelled URB had qTDs.

Subject: USB: ehci: Fix IST boundary checking interval math.

When the EHCI driver falls behind in its scheduling, the active stream's
first empty microframe may be in the past with respect to the current
microframe.  The code attempts to move the starting microframe ("start") N
number of microframes forward, where N is the interval of endpoint.
However, stream->interval is a copy of the endpoint's bInterval, which is
designated in frames for FS devices, and microframes for HS devices.
Convert stream->interval to microframes before using it to move the
starting microframe forward.

usb-storage: Workaround devices with bogus sense size

Some devices, such as Huawei E169, advertise more than the standard
amount of sense data, causing us to set US_FL_SANE_SENSE, assuming
they support it. However, they subsequently fail the request sense
with that size.

This works around it generically. When a sense request fails due to
a device returning an error, US_FL_SANE_SENSE was set, and that sense
request used a larger sense size, we retry with a smaller size before
giving up.

Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The locking logic in this function is extremely subtle, and it broke
when we started doing potentially concurrent 'flush_to_ldisc()' calls in
commit e043e42bdb66885b3ac10d27a01ccb9972e2b0a3 ("pty: avoid forcing
'low_latency' tty flag").

The code in flush_to_ldisc() used to set 'tty->buf.head' to NULL, with
the intention that this would then cause any other concurrent calls to
not do anything (locking note: we have to drop the buf.lock over the
call to ->receive_buf that can block, which is why we can have
concurrency here at all in the first place).

It also used to set the TTY_FLUSHING bit, which would then cause any
concurrent 'tty_buffer_flush()' to not free all the tty buffers and
clear 'tty->buf.tail'.  And with 'buf.head' being NULL, and 'buf.tail'
being non-NULL, new data would never touch 'buf.head'.

Does that sound a bit too subtle? It was.  If another concurrent call to
'flush_to_ldisc()' were to come in, the NULL buf.head would indeed cause
it to not process the buffer list, but it would still clear TTY_FLUSHING
afterwards, making the buffer protection against 'tty_buffer_flush()' no
longer work.

So this clears it all up.  We depend purely on TTY_FLUSHING for handling
re-entrancy, and stop playing games with the buffer list entirely.  In
fact, the buffer list handling is now robust enough that we could
probably stop doing the whole "protect against 'tty_buffer_flush()'"
thing entirely.

However, Alan also points out that we would probably be better off
simplifying the locking even further, and just take the tty ldisc_mutex
around all the buffer flushing calls.  That seems like a good idea, but
in the meantime this is a conceptually minimal fix (with the patch
itself being bigger than required just to clean the code up and make it
readable).

This fixes keyboard trouble under X:

Subject: net/fec_mpc52xx: Fix kernel panic on FEC error

The MDIO bus cannot be accessed at interrupt context, but on an FEC
error, the fec_mpc52xx driver reset function also tries to reset the
PHY.  Since the error is detected at IRQ context, and the PHY functions
try to sleep, the kernel ends up panicking.

Resetting the PHY on an FEC error isn't even necessary.  This patch
solves the problem by removing the PHY reset entirely.

Subject: workqueue: add 'flush_delayed_work()' to run and wait for delayed
 work

It basically turns a delayed work into an immediate work, and then waits
for it to finish, thus allowing you to force (and wait for) an immediate
flush of a delayed work.

We'll want to use this in the tty layer to clean up tty_flush_to_ldisc().

Subject: tty: use the new 'flush_delayed_work()' helper to do ldisc flush

This way all flush_to_ldisc work is always done through the workqueues,
and we thus have a single point of serialization.  It also means that we
can avoid calling flush_to_ldisc() entirely if there was no delayed work
pending.

[ Side note: using workqueues and keventd as the single way to enter
  flush_to_ldisc() still doesn't absolutely guarantee that we can't have
  concurrency: keventd is multithreaded and has a thread per CPU, and
  while the WORK_STRUCT_PENDING bit guarantees a single work only being
  on the pending list once, the work might be both pending and _running_
  at the same time. Workqueues are not simple. ]

This was also confirmed to fix bugzilla #14388, even without the earlier
locking fix and cleanup (commit c8e331419: "tty: Make flush_to_ldisc()
locking more robust").  So both commits fix the same bug differently,
and either would have worked on its own.  But I'm committing them both
since they are cleanups independent of each other.

Subject: sysfs: Allow sysfs_notify_dirent to be called from interrupt context.

sysfs_notify_dirent is a simple atomic operation that can be used to
alert user-space that new data can be read from a sysfs attribute.

Unfortunately it cannot currently be called from non-process context
because of its use of spin_lock which is sometimes taken with
interrupts enabled.

So change all lockers of sysfs_open_dirent_lock to disable interrupts,
thus making sysfs_notify_dirent safe to be called from non-process
context (as drivers/md does in md_safemode_timeout).

sysfs_get_open_dirent is (documented as being) only called from
process context, so it uses spin_lock_irq.  Other places
use spin_lock_irqsave.

The usage for sysfs_notify_dirent in md_safemode_timeout was
introduced in 2.6.28, so this patch is suitable for that and more
recent kernels.

Subject: OMAP: Fix race condition with autodeps

There is a possible race condition in clockdomain
code handling hw supported idle transitions.

When multiple autodeps dependencies are being added
or removed, a transition of still remaining dependent
powerdomain can result in false readings of the
state counter. This is especially fatal for off mode
state counter, as it could result in a driver not
noticing a context loss.

Fixed by disabling hw supported state transitions
when autodeps are being changed.

clock24xx.c is missing a omap2_init_clk_clkdm() in its

Call compat_unimap_ioctl, not do_unimap_ioctl.

This was broken by commit e9216651.

The compat_unimap_ioctl was originally called do_unimap_ioctl in
fs/compat_ioctl.h which got moved to drivers/char/vt_ioctl.c.
In that patch, the caller was not updated and consequently called
the native handler.

Subject: drm/radeon/kms: move active_device setup into encoder fixup()

radeon_encoder->active_device defines the active routing
between the encoder and connector.  The encoder fixup and
dpms functions need to know the active_device to function
properly.  Setting active_device in the prepare hook was
too late in some cases.

This reverts commit e9a63a4e559fbdc522072281d05e6b13c1022f4b.

This breaks older binutils, where sink-less asserts are broken.

Subject: be2net: fix support for PCI hot plug

Before issuing any cmds to the FW, the driver must first wait
till the fW becomes ready. This is needed for PCI hot plug when
the driver can be probed while the card fw is being initialized.

Subject: virtio_net: use dev_kfree_skb_any() in free_old_xmit_skbs()

Because netpoll can call netdevice start_xmit() method with
irqs disabled, drivers should not call kfree_skb() from
their start_xmit(), but use dev_kfree_skb_any() instead.

Subject: rcu: Prevent RCU IPI storms in presence of high call_rcu() load

As the number of callbacks on a given CPU rises, invoke
force_quiescent_state() only every blimit number of callbacks
(defaults to 10,000), and even then only if no other CPU has
invoked force_quiescent_state() in the meantime.

This should fix the performance regression reported by Nick.

Subject: rcu: Stopgap fix for synchronize_rcu_expedited() for TREE_PREEMPT_RCU

For the short term, map synchronize_rcu_expedited() to
synchronize_rcu() for TREE_PREEMPT_RCU and to
synchronize_sched_expedited() for TREE_RCU.

Longer term, there needs to be a real expedited grace period for
TREE_PREEMPT_RCU, but candidate patches to date are considerably
more complex and intrusive.

 Using flexible arrays in the kernel

 Note that it is possible to get back a valid pointer for an element which
 has never been stored in the array.  Memory for array elements is allocated
 one page at a time; a single allocation could provide memory for several
-adjacent elements.  The flexible array code does not know if a specific
-element has been written; it only knows if the associated memory is
-present.  So a flex_array_get() call on an element which was never stored
-in the array has the potential to return a pointer to random data.  If the
-caller does not have a separate way to know which elements were actually
-stored, it might be wise, at least, to add GFP_ZERO to the flags argument
-to ensure that all elements are zeroed.
-
-There is no way to remove a single element from the array.  It is possible,
-though, to remove all elements with a call to:
+adjacent elements.  Flexible array elements are normally initialized to the
+value FLEX_ARRAY_FREE (defined as 0x6c in <linux/poison.h>), so errors
+involving that number probably result from use of unstored array entries.
+Note that, if array elements are allocated with __GFP_ZERO, they will be
+initialized to zero and this poisoning will not happen.
+
+Individual elements in the array can be cleared with:
+
+    int flex_array_clear(struct flex_array *array, unsigned int element_nr);
+
+This function will set the given element to FLEX_ARRAY_FREE and return
+zero.  If storage for the indicated element is not allocated for the array,
+flex_array_clear() will return -EINVAL instead.  Note that clearing an
+element does not release the storage associated with it; to reduce the
+allocated size of an array, call:
+
+    int flex_array_shrink(struct flex_array *array);
+
+The return value will be the number of pages of memory actually freed.
+This function works by scanning the array for pages containing nothing but
+FLEX_ARRAY_FREE bytes, so (1) it can be expensive, and (2) it will not work
+if the array's pages are allocated with __GFP_ZERO.
+
+It is possible to remove all elements of an array with a call to:
 
     void flex_array_free_parts(struct flex_array *array);

Subject: of: Remove nested function
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Some toolchains dislike nested function definition, so we define function match
outside of of_phy_find_device.

Subject: drivers/serial/mpc52xx_uart.c: Use UPIO_MEM rather than SERIAL_IO_MEM

As in the commit 9b4a1617772d6d5ab5eeda0cd95302fae119e359, use UPIO_MEM
rather than SERIAL_IO_MEM.  Both have the same value.

The semantic patch that makes this change is as follows:

Turns out some machines, like the ThinkPad X40 don't come back if you
don't save/restore this register.

Subject: drm/i915: Install a fence register for fbc on g4x

To enable framebuffer compression on a g4x, we not only need the buffer
to tiled (X only), we also need to hold a fence register for the buffer.
Currently we only install a fence register for pre-i965s when setting up
the scanout buffer. Rather than adding some convoluted logic to
g4x_enable_fbc() to acquire a fence register, and perhaps to
g4x_disable_fbc() to release it again, we can extend the acquisition
during setup to all chipsets.

From 1456edbb1476db735715ddcc7ac306de587024eb Mon Sep 17 00:00:00 2001
From: Josh Triplett <josh@joshtriplett.org>
Date: Thu, 15 Oct 2009 11:03:20 -0700
Subject: kconfig: Make zconf.y work with current bison

zconf.y includes zconf.hash.c from the initial code section.
zconf.hash.c references the token constants from zconf.y.  However,
current bison defines the token constants after the initial code
section, making zconf.hash.c fail to compile.  Move the include of
zconf.hash.c later in zconf.y, so bison puts it after the token
constants.

Signed-off-by: Josh Triplett <josh@joshtriplett.org>

Subject: rcu: Fix TREE_PREEMPT_RCU CPU_HOTPLUG bad-luck hang

If the following sequence of events occurs, then
TREE_PREEMPT_RCU will hang waiting for a grace period to
complete, eventually OOMing the system:

o	A TREE_PREEMPT_RCU build of the kernel is booted on a system
	with more than 64 physical CPUs present (32 on a 32-bit system).
	Alternatively, a TREE_PREEMPT_RCU build of the kernel is booted
	with RCU_FANOUT set to a sufficiently small value that the
	physical CPUs populate two or more leaf rcu_node structures.

o	A task is preempted in an RCU read-side critical section
	while running on a CPU corresponding to a given leaf rcu_node
	structure.

o	All CPUs corresponding to this same leaf rcu_node structure
	record quiescent states for the current grace period.

o	All of these same CPUs go offline (hence the need for enough
	physical CPUs to populate more than one leaf rcu_node structure).
	This causes the preempted task to be moved to the root rcu_node
	structure.

At this point, there is nothing left to cause the quiescent
state to be propagated up the rcu_node tree, so the current
grace period never completes.

The simplest fix, especially after considering the deadlock
possibilities, is to detect this situation when the last CPU is
offlined, and to set that CPU's ->qsmask bit in its leaf
rcu_node structure.  This will cause the next invocation of
force_quiescent_state() to end the grace period.

Without this fix, this hang can be triggered in an hour or so on
some machines with rcutorture and random CPU onlining/offlining.
With this fix, these same machines pass a full 10 hours of this
sort of abuse.

Subject: KEYS: get_instantiation_keyring() should inc the keyring refcount in
 all cases

The destination keyring specified to request_key() and co. is made available to
the process that instantiates the key (the slave process started by
/sbin/request-key typically).  This is passed in the request_key_auth struct as
the dest_keyring member.

keyctl_instantiate_key and keyctl_negate_key() call get_instantiation_keyring()
to get the keyring to attach the newly constructed key to at the end of
instantiation.  This may be given a specific keyring into which a link will be
made later, or it may be asked to find the keyring passed to request_key().  In
the former case, it returns a keyring with the refcount incremented by
lookup_user_key(); in the latter case, it returns the keyring from the
request_key_auth struct - and does _not_ increment the refcount.

The latter case will eventually result in an oops when the keyring prematurely
runs out of references and gets destroyed.  The effect may take some time to
show up as the key is destroyed lazily.

To fix this, the keyring returned by get_instantiation_keyring() must always
have its refcount incremented, no matter where it comes from.

This can be tested by setting /etc/request-key.conf to:

#OP	TYPE	DESCRIPTION	CALLOUT INFO	PROGRAM ARG1 ARG2 ARG3 ...
#======	=======	===============	===============	===============================
create  *	test:*		*		|/bin/false %u %g %d %{user:_display}
negate	*	*		*		/bin/keyctl negate %k 10 @u

and then doing:

	keyctl add user _display aaaaaaaa @u
        while keyctl request2 user test:x test:x @u &&
        keyctl list @u;
        do
                keyctl request2 user test:x test:x @u;
                sleep 31;
                keyctl list @u;
        done

which will oops eventually.  Changing the negate line to have @u rather than
%S at the end is important as that forces the latter case by passing a special
keyring ID rather than an actual keyring ID.

Subject: drm/radeon/kms: fix connector edid handling

Based partly on a patch from
Christian Koenig <deathsimple@vodafone.de>

- fix several memory leaks in radeon_connector->edid handling
- store edid in radeon_connector->edid in detect() or get_modes()
- switch hdmi detect code to use radeon_connector->edid
- add support for oem boards multiple connectors that share
a ddc line.
- short circuit lvds_detect() if have a stored edid

Subject: drm: Add the basic check for the detailed timing in EDID

Sometimes we will get the incorrect display modeline when parsing the detailed
timing in EDID. For example:
   >hsync/vsync width is zero
   >sync is beyond the blank.

So add the basic check for the detailed timing in EDID to avoid the incorrect
display modeline.

 blocked"

This reverts commit df10cfbc4d7ab93260d997df754219d390d62a9d.

This patch was based on a misunderstanding and risks introducing a busy-wait loop.
So revert it.

Subject: md/raid1/raid10: add a cond_resched

During 'check' of a raid1 or raid10 it is possible for the management
thread to spend a lot of time running 'memcmp' on blocks from
different devices, so make sure the thread has a chance to schedule.
raid5d already has a cond_resched (in process_stripe).

Deallocating a raid5_conf_t structure requires taking 'device_lock'.
Ensure it is initialized before it is used, i.e. initialize the lock
before attempting any further initializations that might fail.

Subject: md: raid1/raid10: handle allocation errors during array setup.

Both raid1 and raid10 create a mempool during startup.
If the 'alloc' function for this mempool fails, unplug_slaves
is called.
If that happens when the pool is being initialised, unplug_slaves
will try to use the 'conf' structure that isn't filled in yet, and
badness will happen.

So ensure that unplug_slaves doesn't get called unless we know
that the conf structure if fully initialised.

Subject: md: remove clumsy usage of do_sync_mapping_range from bitmap code

and replace with vfs_fsync which is much neater (but wasn't exported,
or even in existence at the time the code was written).

Subject: sh: Fix up single page flushing to use PAGE_SIZE.

Presently The SH-4 cache flushing code uses flush_cache_4096() for most
of the real flushing work, which breaks down to a fixed 4096 unroll and
increment. Not only is this sub-optimal for larger page sizes, it's also
uncovered a bug in sh4_flush_dcache_page() when large page sizes are used
and we have no cache aliases -- resulting in only a part of the page's
D-cache lines being written back.

Subject: x86: Document linker script ASSERT() quirk

Older binutils breaks if ASSERT() is used without a sink
for the output.

For example 2.14.90.0.6 is known to be broken, the link
fails with:

  LD      .tmp_vmlinux1
  ld:arch/x86/kernel/vmlinux.lds:678: parse error

Document this quirk in all three files that use it.

  See:    http://marc.info/?l=linux-kbuild&m=124930110427870&w=2
  See[2]: d2ba8b2 ("x86: Fix assert syntax in vmlinux.lds.S")

Subject: md/raid456: downlevel multicore operations to raid_run_ops

The percpu conversion allowed a straightforward handoff of stripe
processing to the async subsytem that initially showed some modest gains
(+4%).  However, this model is too simplistic and leads to stripes
bouncing between raid5d and the async thread pool for every invocation
of handle_stripe().  As reported by Holger this can fall into a
pathological situation severely impacting throughput (6x performance
loss).

By downleveling the parallelism to raid_run_ops the pathological
stripe_head bouncing is eliminated.  This version still exhibits an
average 11% throughput loss for:

	mdadm --create /dev/md0 /dev/sd[b-q] -n 16 -l 6
	echo 1024 > /sys/block/md0/md/stripe_cache_size
	dd if=/dev/zero of=/dev/md0 bs=1024k count=2048

...but the results are at least stable and can be used as a base for
further multicore experimentation.

Subject: md: Fix handling of raid5 array which is being reshaped to fewer
 devices.

When a raid5 (or raid6) array is being reshaped to have fewer devices,
conf->raid_disks is the latter and hence smaller number of devices.
However sometimes we want to use a number which is the total number of
currently required devices - the larger of the 'old' and 'new' sizes.
Before we implemented reducing the number of devices, this was always
'new' i.e. ->raid_disks.
Now we need max(raid_disks, previous_raid_disks) in those places.

This particularly affects assembling an array that was shutdown while
in the middle of a reshape to fewer devices.

md.c needs a similar fix when interpreting the md metadata.

Subject: md/async: don't pass a memory pointer as a page pointer.

md/raid6 passes a list of 'struct page *' to the async_tx routines,
which then either DMA map them for offload, or take the page_address
for CPU based calculations.

For RAID6 we sometime leave 'blanks' in the list of pages.
For CPU based calcs, we want to treat theses as a page of zeros.
For offloaded calculations, we simply don't pass a page to the
hardware.

Currently the 'blanks' are encoded as a pointer to
raid6_empty_zero_page.  This is a 4096 byte memory region, not a
'struct page'.  This is mostly handled correctly but is rather ugly.

So change the code to pass and expect a NULL pointer for the blanks.
When taking page_address of a page, we need to check for a NULL and
in that case use raid6_empty_zero_page.

Subject: raid6/async_tx: handle holes in block list in async_syndrome_val

async_syndrome_val check the P and Q blocks used for RAID6
calculations.
With DDF raid6, some of the data blocks might be NULL, so
this needs to be handled in the same way that async_gen_syndrome
handles it.

As async_syndrome_val calls async_xor, also enhance async_xor
to detect and skip NULL blocks in the list.

Subject: sh: Remove BKL from landisk gio.

The open function got the BKL via the big push down. Replace it by
preempt_enable/disable as this is sufficient for an UP machine.

The ioctl can be unlocked because there is no functionality which
requires serialization. The usage by multiple callers is broken with
and without the BKL due to the local static variable addr.

Subject: x86, UV: Fix information in __uv_hub_info structure

A few parts of the uv_hub_info structure are initialized
incorrectly.

 - n_val is being loaded with m_val.
 - gpa_mask is initialized with a bytes instead of an unsigned long.
 - Handle the case where none of the alias registers are used.

Lastly I converted the bau over to using the uv_hub_info->m_val
which is the correct value.

Without this patch, booting a large configuration hits a
problem where the upper bits of the gnode affect the pnode
and the bau will not operate.

Subject: x86: Don't print number of MCE banks for every CPU

The MCE initialization code explicitly says it doesn't handle
asymmetric configurations where different CPUs support different
numbers of MCE banks, and it prints a big warning in that case.

Therefore, printing the "mce: CPU supports <x> MCE banks"
message into the kernel log for every CPU is pure redundancy
that clutters the log significantly for systems with lots of
CPUs.

Subject: futex: Move drop_futex_key_refs out of spinlock'ed region

When requeuing tasks from one futex to another, the reference held
by the requeued task to the original futex location needs to be
dropped eventually.

Dropping the reference may ultimately lead to a call to
"iput_final" and subsequently call into filesystem- specific code -
which may be non-atomic.

It is therefore safer to defer this drop operation until after the
futex_hash_bucket spinlock has been dropped.

Original radeon didn't have a connector table in the

add a VGA connector.

Subject: sata_nv: make sure link is brough up online when skipping hardreset

prereset doesn't bring link online if hardreset is about to happen and
nv_hardreset() may skip if conditions are not right so softreset may
be entered with non-working link status if the system firmware didn't
bring it up before entering OS code which can happen during resume.
This patch makes nv_hardreset() to bring up the link if it's skipping
reset.

This bug was reported by frodone@gmail.com in the following bug entry.

Subject: libata: fix PMP initialization

Commit 842faa6c1a1d6faddf3377948e5cf214812c6c90 fixed error handling
during attach by not committing detected device class to dev->class
while attaching a new device.  However, this change missed the PMP
class check in the configuration loop causing a new PMP device to go
through ata_dev_configure() as if it were an ATA or ATAPI device.

As PMP device doesn't have a regular IDENTIFY data, this makes
ata_dev_configure() tries to configure a PMP device using an invalid
data.  For the most part, it wasn't too harmful and went unnoticed but
this ends up clearing dev->flags which may have ATA_DFLAG_AN set by
sata_pmp_attach().  This means that SATA_PMP_FEAT_NOTIFY ends up being
disabled on PMPs and on PMPs which honor the flag breaks hotplug
support.

This problem was discovered and reported by Ethan Hsiao.

Subject: libata: fix internal command failure handling

When an internal command fails, it should be failed directly without
invoking EH.  In the original implemetation, this was accomplished by
letting internal command bypass failure handling in ata_qc_complete().
However, later changes added post-successful-completion handling to
that code path and the success path is no longer adequate as internal
command failure path.  One of the visible problems is that internal
command failure due to timeout or other freeze conditions would
spuriously trigger WARN_ON_ONCE() in the success path.

This patch updates failure path such that internal command failure
handling is contained there.

Subject: pata_sc1200: Fix crash on boot

The SC1200 needs a NULL terminator or it may cause a crash on boot.

Bug #14227

Also correct a bogus comment as the driver had serializing added so can run
dual port.

Subject: sata_mv: Prevent PIO commands to be defered too long if traffic in
 progress.

Use excl_link when non NCQ commands are defered, to be sure they are processed
as soon as outstanding commands are completed. It prevents some commands to be
defered indifinitely when using a port multiplier.

Create an inline function to extract the pnode from a global
physical address and then convert the broadcast assist unit to
use the newly created uv_gpa_to_pnode function.

The open-coded code was wrong as well - it might explain a
few of our unexplained bau hangs.

Subject: KVM: Prevent kvm_init from corrupting debugfs structures

I'm seeing an oops condition when kvm-intel and kvm-amd are modprobe'd
during boot (say on an Intel system) and then rmmod'd:

   # modprobe kvm-intel
     kvm_init()
     kvm_init_debug()
     kvm_arch_init()  <-- stores debugfs dentries internally
     (success, etc)

   # modprobe kvm-amd
     kvm_init()
     kvm_init_debug() <-- second initialization clobbers kvm's
                          internal pointers to dentries
     kvm_arch_init()
     kvm_exit_debug() <-- and frees them

   # rmmod kvm-intel
     kvm_exit()
     kvm_exit_debug() <-- double free of debugfs files!

     *BOOM*

If execution gets to the end of kvm_init(), then the calling module has been
established as the kvm provider.  Move the debugfs initialization to the end of
the function, and remove the now-unnecessary call to kvm_exit_debug() from the
error path.  That way we avoid trampling on the debugfs entries and freeing
them twice.

Subject: dm snapshot: sort by chunk size to fix race

Avoid a race causing corruption when snapshots of the same origin have
different chunk sizes by sorting the internal list of snapshots by chunk
size, largest first.
  https://bugzilla.redhat.com/show_bug.cgi?id=182659

For example, let's have two snapshots with different chunk sizes. The
first snapshot (1) has small chunk size and the second snapshot (2) has
large chunk size.  Let's have chunks A, B, C in these snapshots:
snapshot1: ====A====   ====B====
snapshot2: ==========C==========

(Chunk size is a power of 2. Chunks are aligned.)

A write to the origin at a position within A and C comes along. It
triggers reallocation of A, then reallocation of C and links them
together using A as the 'primary' exception.

Then another write to the origin comes along at a position within B and
C.  It creates pending exception for B.  C already has a reallocation in
progress and it already has a primary exception (A), so nothing is done
to it: B and C are not linked.

If the reallocation of B finishes before the reallocation of C, because
there is no link with the pending exception for C it does not know to
wait for it and, the second write is dispatched to the origin and causes
data corruption in the chunk C in snapshot2.

To avoid this situation, we maintain snapshots sorted in descending
order of chunk size.  This leads to a guaranteed ordering on the links
between the pending exceptions and avoids the problem explained above -
both A and B now get linked to C.

While initializing the snapshot module, if we fail to register
the snapshot target then we must back-out the exception store
module initialization.

Subject: dm: dec_pending needs locking to save error value

Multiple instances of dec_pending() can run concurrently so a lock is
needed when it saves the first error code.

I have never experienced actual problem without locking and just found
this during code inspection while implementing the barrier support
patch for request-based dm.

This patch adds the locking.
I've done compile, boot and basic I/O testings.

If we are creating snapshot with memory-stored exception store, fail if
the user didn't specify chunk size. Zero chunk size would probably crash
a lot of places in the rest of snapshot code.

Subject: dm snapshot: use unsigned integer chunk size

Use unsigned integer chunk size.

Maximum chunk size is 512kB, there won't ever be need to use 4GB chunk size,
so the number can be 32-bit. This fixes compiler failure on 32-bit systems
with large block devices.

Subject: dm snapshot: allow chunk size to be less than page size

Allow the snapshot chunk size to be smaller than the page size
The code is now capable of handling this due to some previous
fixes and enhancements.

As the page size varies between computers, prior to this patch,
the chunk size of a snapshot dictated which machines could read it:
Snapshots created on one machine might not be readable on another.

Subject: vmxnet3: use dev_dbg, fix build for CONFIG_BLOCK=n

vmxnet3 was using dprintk() for debugging output.  This was
defined in <linux/dst.h> and was the only thing that was
used from that header file.  This caused compile errors
when CONFIG_BLOCK was not enabled due to bio* and BIO*

Subject: [ARM] pxa/spitz: add gpio button support (fixes regression)

Updating desc for lid keys and resending patch with proper comments:
Define Spitz buttons as GPIO keys in a way compatible with the old driver:

On/Off: As Suspend EV_PWR key
Raw values of lid sensors SWA and SWB: As EV_SW switches
SWA: Display Down
SWB: Lid Closed
Recommended user space decoding:
SWA==0 & SWB==0: lid opened (landscape mode)
SWA==1 & SWB==0: invalid (or mechanic race condition)
SWA==0 & SWB==1: lid closed with display up (portrait mode or mechanic
                 race condition while closing to display-less mode)
SWA==1 & SWB==1: lid closed with display down (display-less mode)

AK_INT remote trigger is not mapped as input event. Without complete
remote driver and remote pull-up control it has no useful
interpretation.

Subject: Input: i8042 - add Sony Vaio VGN-FZ240E to the nomux list

On this model, when KBD is in active multiplexing mode, acknowledgements
to reset and get ID commands issued on KBD port sometimes are delivered
to AUX3 port (touchpad) which messes up device detection. Legacy KBC
mode works fine and since there are no external PS/2 ports on this laptop
and no support for docking station we can safely disable active MUX mode.

Subject: fsnotify: do not set group for a mark before it is on the i_list

fsnotify_add_mark is supposed to add a mark to the g_list and i_list and to
set the group and inode for the mark.  fsnotify_destroy_mark_by_entry uses
the fact that ->group != NULL to know if this group should be destroyed or
if it's already been done.

But fsnotify_add_mark sets the group and inode before it actually adds the
mark to the i_list and g_list.  This can result in a race in inotify, it
requires 3 threads.

sys_inotify_add_watch("file")	sys_inotify_add_watch("file")	sys_inotify_rm_watch([a])
inotify_update_watch()
inotify_new_watch()
inotify_add_to_idr()
   ^--- returns wd = [a]
				inotfiy_update_watch()
				inotify_new_watch()
				inotify_add_to_idr()
				fsnotify_add_mark()
				   ^--- returns wd = [b]
				returns to userspace;
								inotify_idr_find([a])
								   ^--- gives us the pointer from task 1
fsnotify_add_mark()
   ^--- this is going to set the mark->group and mark->inode fields, but will
return -EEXIST because of the race with [b].
								fsnotify_destroy_mark()
								   ^--- since ->group != NULL we call back
									into inotify_freeing_mark() which calls
								inotify_remove_from_idr([a])

since fsnotify_add_mark() failed we call:
inotify_remove_from_idr([a])     <------WHOOPS it's not in the idr, this could
					have been any entry added later!

The fix is to make sure we don't set mark->group until we are sure the mark is
on the inode and fsnotify_add_mark will return success.

Subject: inotify: fix coalesce duplicate events into a single event in special
 case

If we do rename a dir entry, like this:

  rename("/tmp/ino7UrgoJ.rename1", "/tmp/ino7UrgoJ.rename2")
  rename("/tmp/ino7UrgoJ.rename2", "/tmp/ino7UrgoJ")

The duplicate events should be coalesced into a single event. But those two
events do not be coalesced into a single event, due to some bad check in
event_compare(). It can not match the two NULL inodes as the same event.

Subject: pcmcia: pccard_read_tuple and TUPLE_RETURN_COMMON cleanup

pccard_read_tuple(), which is only used by the PCMCIA core, should
handle TUPLE_RETURN_COMMON more sensibly: If a specific function (which
may be 0) is requested, set tuple.Attributes = 0 as was done in all
PCMCIA drivers. If, however, BIND_FN_ALL is requested, return the
"common" tuple. As to the callers of pccard_read_tuple():

- All calls to pcmcia_validate_cis() had set the "function" parameter to
  BIND_FN_ALL. Therefore, remove the "function" parameter and make the
  parameter to pccard_read_tuple explicit.

- Calls to CISTPL_VERS_1 and CISTPL_MANFID now set BIND_FN_ALL. This was
  already the case for calls to CISTPL_LONGLINK_MFC.

Subject: HWPOISON: return early on non-LRU pages

Right now we have some trouble with non atomic access
to page flags when locking the page. To plug this hole
for now, limit error recovery to LRU pages for now.

This could be better fixed by defining a suitable protocol,
but let's go this simple way for now

This avoids unnecessary races with __set_page_locked() and
__SetPageSlab*() and maybe more non-atomic page flag operations.

This loses isolated pages which are currently in page reclaim, but these
are relatively limited compared to the total memory.

When returning due to a poisoned page drop the page count.

It wasn't a fatal problem because noone cares about the page count
on a poisoned page (except when it wraps), but it's cleaner to fix it.

Pointed out by Linus.

Memory failure on a KSM page currently oopses on its NULL anon_vma in

of ignoring it, but it is better to be consistent with how ZERO_PAGE

Subject: HWPOISON: Allow schedule_on_each_cpu() from keventd

Right now when calling schedule_on_each_cpu() from keventd there
is a deadlock because it tries to schedule a work item on the current CPU
too. This happens via lru_add_drain_all() in hwpoison.

Just call the function for the current CPU in this case. This is actually
faster too.

Subject: AF_UNIX: Fix deadlock on connecting to shutdown socket

I found a deadlock bug in UNIX domain socket, which makes able to DoS
attack against the local machine by non-root users.

How to reproduce:
1. Make a listening AF_UNIX/SOCK_STREAM socket with an abstruct
    namespace(*), and shutdown(2) it.
 2. Repeat connect(2)ing to the listening socket from the other sockets
    until the connection backlog is full-filled.
 3. connect(2) takes the CPU forever. If every core is taken, the
    system hangs.

PoC code: (Run as many times as cores on SMP machines.)

int main(void)
{
	int ret;
	int csd;
	int lsd;
	struct sockaddr_un sun;

	/* make an abstruct name address (*) */
	memset(&sun, 0, sizeof(sun));
	sun.sun_family = PF_UNIX;
	sprintf(&sun.sun_path[1], "%d", getpid());

	/* create the listening socket and shutdown */
	lsd = socket(AF_UNIX, SOCK_STREAM, 0);
	bind(lsd, (struct sockaddr *)&sun, sizeof(sun));
	listen(lsd, 1);
	shutdown(lsd, SHUT_RDWR);

	/* connect loop */
	alarm(15); /* forcely exit the loop after 15 sec */
	for (;;) {
		csd = socket(AF_UNIX, SOCK_STREAM, 0);
		ret = connect(csd, (struct sockaddr *)&sun, sizeof(sun));
		if (-1 == ret) {
			perror("connect()");
			break;
		}
		puts("Connection OK");
	}
	return 0;
}

(*) Make sun_path[0] = 0 to use the abstruct namespace.
    If a file-based socket is used, the system doesn't deadlock because
    of context switches in the file system layer.

Why this happens:
 Error checks between unix_socket_connect() and unix_wait_for_peer() are
 inconsistent. The former calls the latter to wait until the backlog is
 processed. Despite the latter returns without doing anything when the
 socket is shutdown, the former doesn't check the shutdown state and
 just retries calling the latter forever.

Patch:
 The patch below adds shutdown check into unix_socket_connect(), so
 connect(2) to the shutdown socket will return -ECONREFUSED.

Subject: ASoC: Fix possible codec_dai->ops NULL pointer problems

Some codec DAIs like stac9766, wm9712, wm9713, ad1980 don't register themselves
then it loses to the chance to be given a null_dai_ops in snd_soc_register_dai
if they have no ops. When functions like soc_pcm_open, soc_pcm_hw_params etc.
access the ops field in these DAIs, panic will happen.

Subject: drm/i915: fix to setup display reference clock control on Ironlake

For new stepping of PCH, the display reference clock
is fully under driver's control. This one trys to setup
all needed reference clock for different outputs. Older
stepping of PCH chipset should be ignoring this.

This fixes output failure issue on newer PCH which requires
driver to take control of reference clock enabling.

Subject: perf timechart: Fix the wakeup-arrows that point to non-visible
 processes

The timechart wakeup arrows currently show no process
information when the waker/wakee are processes that are not
actually chosen to be shown on the timechart.

This patch fixes this oversight, by looking through all
processes (after giving preference to visible processes) as well
as falling back to just showing the PID if no name for the
process can be resolved.

Subject: perf timechart: Improve the visual appearance of scheduler delays

[from KS feedback]

Currently, scheduler delays are shown in a mostly transparent,
light yellow color. This color is rather hard to see on several
screens, especially projectors.

This patch changes the color of the scheduler delays to be a
much more "hard" yellow that survived the kernel summit
projector.

Subject: tcp: accept socket after TCP_DEFER_ACCEPT period

Willy Tarreau and many other folks in recent years
were concerned what happens when the TCP_DEFER_ACCEPT period
expires for clients which sent ACK packet. They prefer clients
that actively resend ACK on our SYN-ACK retransmissions to be
converted from open requests to sockets and queued to the
listener for accepting after the deferring period is finished.
Then application server can decide to wait longer for data
or to properly terminate the connection with FIN if read()
returns EAGAIN which is an indication for accepting after
the deferring period. This change still can have side effects
for applications that expect always to see data on the accepted
socket. Others can be prepared to work in both modes (with or
without TCP_DEFER_ACCEPT period) and their data processing can
ignore the read=EAGAIN notification and to allocate resources for
clients which proved to have no data to send during the deferring
period. OTOH, servers that use TCP_DEFER_ACCEPT=1 as flag (not
as a timeout) to wait for data will notice clients that didn't
send data for 3 seconds but that still resend ACKs.
Thanks to Willy Tarreau for the initial idea and to
Eric Dumazet for the review and testing the change.

Subject: tcp: reduce SYN-ACK retrans for TCP_DEFER_ACCEPT

Change SYN-ACK retransmitting code for the TCP_DEFER_ACCEPT
users to not retransmit SYN-ACKs during the deferring period if
ACK from client was received. The goal is to reduce traffic
during the deferring period. When the period is finished
we continue with sending SYN-ACKs (at least one) but this time
any traffic from client will change the request to established
socket allowing application to terminate it properly.
Also, do not drop acked request if sending of SYN-ACK fails.

Fix TCP_DEFER_ACCEPT conversion between seconds and
retransmission to match the TCP SYN-ACK retransmission periods
because the time is converted to such retransmissions. The old
algorithm selects one more retransmission in some cases. Allow
up to 255 retransmissions.

Subject: net: Fix IP_MULTICAST_IF

ipv4/ipv6 setsockopt(IP_MULTICAST_IF) have dubious __dev_get_by_index() calls.

This function should be called only with RTNL or dev_base_lock held, or reader
could see a corrupt hash chain and eventually enter an endless loop.

Fix is to call dev_get_by_index()/dev_put().

If this happens to be performance critical, we could define a new dev_exist_by_index()
function to avoid touching dev refcount.

Subject: async_pq: rename scribble page

The global scribble page is used as a temporary destination buffer when
disabling the P or Q result is requested.  The local scribble buffer
contains memory for performing address conversions.  Rename the global
variable to avoid confusion.

Subject: async_tx: fix asynchronous raid6 recovery for ddf layouts

The raid6 recovery code currently requires special handling of the
4-disk and 5-disk recovery scenarios for the native layout.  Quoting
from commit 0a82a623:

     In these situations the default N-disk algorithm will present
     0-source or 1-source operations to dma devices.  To cover for
     dma devices where the minimum source count is 2 we implement
     4-disk and 5-disk handling in the recovery code.

The ddf layout presents disks=6 and disks=7 to the recovery code in
these situations.  Instead of looking at the number of disks count the
number of non-zero sources in the list and call the special case code
when the number of non-failed sources is 0 or 1.

Subject: UBI: fix backward compatibility

Commit 32bc4820287a1a03982979515949e8ea56eac641 did not fully fix
the backward compatibility issues. We still fail to properly handle
situations when the first PEB contains non-zero image sequence
number, but one of the following PEBs contains zero image sequence
number. For example, this may happen if we mount a new image with
an old kernel, and then try to mount it in the new kernel.

This patch should fix the issue.

Subject: crypto: aesni-intel - Fix irq_fpu_usable usage

When renaming kernel_fpu_using to irq_fpu_usable, the semantics of the
function is changed too, from mesuring whether kernel is using FPU,
that is, the FPU is NOT available, to measuring whether FPU is usable,
that is, the FPU is available.

But the usage of irq_fpu_usable in aesni-intel_glue.c is not changed
accordingly. This patch fixes this.

Subject: tcp: Try to catch MSG_PEEK bug

This patch tries to print out more information when we hit the
MSG_PEEK bug in tcp_recvmsg.  It's been around since at least
2005 and it's about time that we finally fix it.

Subject: net: Fix struct inet_timewait_sock bitfield annotation

commit 9e337b0f (net: annotate inet_timewait_sock bitfields)
added 4/8 bytes in struct inet_timewait_sock.

Fix this by declaring tw_ipv6_offset in the 'flags' bitfield
The 14 bits hole is named tw_pad to make it cleary apparent.

spurious events.

Subject: KS8851: Fix ks8851_set_rx_mode() for IFF_MULTICAST

In ks8851_set_rx_mode() the case handling IFF_MULTICAST was also setting
the RXCR1_AE bit by accident. This meant that all unicast frames where
being accepted by the device. Remove RXCR1_AE from this case.

Note, RXCR1_AE was also masking a problem with setting the MAC address
properly, so needs to be applied after fixing the MAC write order.

Fixes a bug reported by Doong, Ping of Micrel. This version of the
patch avoids setting RXCR1_ME for all cases.

Subject: x86, UV: Set DELIVERY_MODE=4 for vector=NMI_VECTOR in
 uv_hub_send_ipi()

When sending a NMI_VECTOR IPI using the UV_HUB_IPI_INT register,
we need to ensure the delivery mode field of that register has
NMI delivery selected.

This makes those IPIs true NMIs, instead of flat IPIs. It
matters to reboot sequences and KGDB, both of which use NMI
IPIs.

Subject: fs: pipe.c null pointer dereference

This patch fixes a null pointer exception in pipe_rdwr_open() which
generates the stack trace:

> Unable to handle kernel NULL pointer dereference at 0000000000000028 RIP:
>  [<ffffffff802899a5>] pipe_rdwr_open+0x35/0x70
>  [<ffffffff8028125c>] __dentry_open+0x13c/0x230
>  [<ffffffff8028143d>] do_filp_open+0x2d/0x40
>  [<ffffffff802814aa>] do_sys_open+0x5a/0x100
>  [<ffffffff8021faf3>] sysenter_do_call+0x1b/0x67

The failure mode is triggered by an attempt to open an anonymous
pipe via /proc/pid/fd/* as exemplified by this script:

=============================================================
while : ; do
   { echo y ; sleep 1 ; } | { while read ; do echo z$REPLY; done ; } &
   PID=$!
   OUT=$(ps -efl | grep 'sleep 1' | grep -v grep |
        { read PID REST ; echo $PID; } )
   OUT="${OUT%% *}"
   DELAY=$((RANDOM * 1000 / 32768))
   usleep $((DELAY * 1000 + RANDOM % 1000 ))
   echo n > /proc/$OUT/fd/1                 # Trigger defect
done
=============================================================

Note that the failure window is quite small and I could only
reliably reproduce the defect by inserting a small delay
in pipe_rdwr_open(). For example:

 static int
 pipe_rdwr_open(struct inode *inode, struct file *filp)
 {
       msleep(100);
       mutex_lock(&inode->i_mutex);

Although the defect was observed in pipe_rdwr_open(), I think it
makes sense to replicate the change through all the pipe_*_open()
functions.

The core of the change is to verify that inode->i_pipe has not
been released before attempting to manipulate it. If inode->i_pipe
is no longer present, return ENOENT to indicate so.

The comment about potentially using atomic_t for i_pipe->readers
and i_pipe->writers has also been removed because it is no longer
relevant in this context. The inode->i_mutex lock must be used so
that inode->i_pipe can be dealt with correctly.

Increase TEST_SUSPEND_SECONDS to 10 so the warning in
suspend_test_finish() doesn't annoy the users of slower systems so much.

Also, make the warning print the suspend-resume cycle time, so that we
know why the warning actually triggered.

Patch prepared during the hacking session at the Kernel Summit in Tokyo.

Subject: [SCSI] zfcp: Handle WWPN mismatch in PLOGI payload

For ports, zfcp gets the DID from the FC nameserver and tries to open
the port. If the open succeeds, zfcp compares the WWPN from the
nameserver with the WWPN in the PLOGI payload. In case of a mismatch,
zfcp assumes that the DID of the port just changed and we opened the
wrong port. This means that zfcp has to forget the DID, lookup the DID
again and retry.

This error case had a problem that zfcp forgets the DID, but never
looks up a new one, stalling the ERP in this case. Fix this by
triggering the DID lookup and properly exit from the ERP. The DID
lookup will trigger a new ERP action.

Also ensure when trying to open the port again with the new DID, first
close the open port, even in the NOESC case.

Subject: [SCSI] zfcp: Warn about storage devices with broken PLOGI data

After opening a remote port zfcp checks if the WWPN returned in the
PLOGI maches the WWPN of the port that should have been opened. On a
mismatch zfcp assumes that the DID just changed, queries the FC
nameserver and tries again. If the situation persists the erp will
give up.

With this strategy, if the remote port always returns the wrong PLOGI
data, the remote port will not be opened. Introduce a warning, so that
the system administrator knows why the remote port is not being opened
and to have a pointer to investigate the problem on the storage
system.

Subject: [SCSI] zfcp: Flush SCSI registration work when adding unit

When configuring a LUN for use in zfcp, flush the SCSI work to ensure
the SCSI device has been created before returning. This means that a
configuration procedure can run these commands in a script and the
SCSI device is available immediately after the unit_add:

echo 1 > /sys/bus/ccw/drivers/zfcp/0.0.181d/online
echo 0x401040C300000000 > \
        /sys/bus/ccw/drivers/zfcp/0.0.181d/0x500507630313c562/unit_add

Subject: virtio_blk: revert QUEUE_FLAG_VIRT addition

It seems like the addition of QUEUE_FLAG_VIRT caueses major performance
regressions for Fedora users:

	https://bugzilla.redhat.com/show_bug.cgi?id=509383
	https://bugzilla.redhat.com/show_bug.cgi?id=505695

while I can't reproduce those extreme regressions myself I think the flag
is wrong.

Rationale:

  QUEUE_FLAG_VIRT expands to QUEUE_FLAG_NONROT which casus the queue
  unplugged immediately.  This is not a good behaviour for at least
  qemu and kvm where we do have significant overhead for every
  I/O operations.  Even with all the latested speeups (native AIO,
  MSI support, zero copy) we can only get native speed for up to 128kb
  I/O requests we already are down to 66% of native performance for 4kb
  requests even on my laptop running the Intel X25-M SSD for which the
  QUEUE_FLAG_NONROT was designed.
  If we ever get virtio-blk overhead low enough that this flag makes
  sense it should only be set based on a feature flag set by the host.

Subject: virtio: let header files include virtio_ids.h

Rusty,

commit 3ca4f5ca73057a617f9444a91022d7127041970a
    virtio: add virtio IDs file
moved all device IDs into a single file. While the change itself is
a very good one, it can break userspace applications. For example
if a userspace tool wanted to get the ID of virtio_net it used to
include virtio_net.h. This does no longer work, since virtio_net.h
does not include virtio_ids.h.
This patch moves all "#include <linux/virtio_ids.h>" from the C
files into the header files, making the header files compatible with
the old ones.

In addition, this patch exports virtio_ids.h to userspace.

Subject: virtio_blk: Revert serial number support

This reverts "Add serial number support for virtio_blk, V4a".

Turns out that virtio_pci, lguest and s/390 all have an 8 bit limit
on virtio config space, so noone could ever use this.

This is coming back later in a cleaner form.

The function virtrng_remove is used only wrapped by __devexit_p so define
it using __devexit.

Subject: Input: atkbd - add a quirk for OQO 01+ multimedia keys

OQO 01+ multimedia keys produce 6x on press, e0 6x upon release.
As a result, Linux thinks that another key has been pressed (or is
repeating), when it is actually a release of the same key. Mangle the
release scancode when running on OQO so that driver recognizes it as
such.

Since the device does not have external PS/2 ports mangling is safe
since there is no chance that an external keyboard is connected.

Subject: omap: Fix omap-keypad by restoring old keypad.h without breaking
 omap2 boards that use matrix_keypad

Only mach-omap2 boards are currently using matrix_keypad. Allow
mach-omap1 boards to use the old style keypad.h without breaking.

Created against linux-2.6.32-rc5.
Compile tested with omap_3430sdp_defconfig and rx51_defconfig.

OMAP sDMA driver API omap_stop_dma() doesn't really stop the dma when used
in linking scenario.

The DMA channel needs to be disabled before resetting the chain.
Also fix clearing of the OMAP_DMA_ACTIVE status in the linked case.

Subject: omap1: Fix redundant UARTs pin muxing that can break other hardware
 support

Commit 15ac408ee5a509053a765b816e9179515329369f removed enabled_uart
and OMAP_TAG_UART. This works for mach-omap2, but causes issues on
mach-omap1 for some boards as the mach-omap1 serial.c was muxing
pins based on the enabled_uart flag for 15xx.

Fix this by muxing pins in board-*.c files for the 15xx boards for
the uart ports that had enabled_uart flag set before the commit
above.

Tested on Amsdtrad Delta only.

Note that in the future we should add support for powering down
the uarts with a timer like mach-omap2/serial.c does. Otherwise
the enabled uarts will be blocking retention-while-idle.

Subject: omap1: Fix DSP public peripherals support for ams-delta

DSP public peripherals used to work on OMAP1510 based (or all OMAP1 class?)
machines as long as old dspgateway code were present in the l-o tree. For
several months it is no longer included, breaking support for McBSP1 based
audio on Amstrad Delta, for example.

This patch, derived from the old dspgateway code, corrects the problem for the
board by simply taking the DSP out of reset state, I guess. That way, things
should not break when a new dsp code is added to the tree, and the change can
be reverted then.

If there are any reports on McBSP1 or other DSP public peripherals not working
for other OMAP1 machines (I've not heard of any for now), I can prepare a more
general patch providing an extra include file with a helper function defined.

Created and tested against linux-2.6.32-rc5

Subject: omap3: PM: enable UART3 module wakeups

UART3 is in the PER powerdomain.  If PER goes idle/inactive
independently of CORE, for UART3 to wakeup it must have its wakeup
enable bits setup in PM_WKEN_PER.  This patch enables these bits.

The reason it works when PER and CORE work together is because when
CORE goes inactive/retention, the IOPAD wakeups are enabled and
trigger UART3 wakeup.

Without this patch, when the UART inactivity timer fires for UART3,
its clocks are disabled and it's unable to wakeup so will be unusable
until PER is awoken by another source.

Another way of testing is by keeping CORE on during suspend but
allowing PER to hit retention

  # echo 3 > /debug/pm_debug/core_pwrdm/suspend

then enter suspend

  # echo mem > /sys/power/state

Without this patch, UART3 will be unable to wakeup the system.

This patch enables omap_serial_early_init() function for OMAP4430
SDP. Without this the bootup would throw oops in omap_serial_init().

Note that the ifndef CONFIG_ARCH_OMAP4 is split into two sections
to enable omap_serial_early_init(). This ifndef cannot be removed
until omap4 clock framework is implemented.

Subject: netxen: avoid undue board config check

Old code assumed board config version in the flash to be 1.
When this will get changed by tools, driver just refuses to
attach. This is unnecessary since driver does not have to
parse board config structure directly (maintained by firmware).

Subject: isdn: fix possible circular locking dependency
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

There's a circular locking dependency:

---> isdn_net_get_locked_lp
    --->lock &nd->queue_lock
    --->lock &nd->queue->xmit_lock
    .....................
    ---->unlock &nd->queue_lock

---> isdn_net_writebuf_skb (called with &nd->queue->xmit_lock locked)
    ---->isdn_net_inc_frame_cnt
         ---->isdn_net_device_busy
              ----> lock &nd->queue_lock

This will trigger lockdep warnings:

 =======================================================
 [ INFO: possible circular locking dependency detected ]
 2.6.32-rc4-testing #7
 -------------------------------------------------------
 ipppd/28379 is trying to acquire lock:
 (&netdev->queue_lock){......}, at: [<e62ad0fd>] isdn_net_device_busy+0x2c/0x74 [isdn]

 but task is already holding lock:
 (&netdev->local->xmit_lock){+.....}, at: [<e62aefc2>] isdn_net_write_super+0x3f/0x6e [isdn]

 which lock already depends on the new lock.
 .......

 We don't need to lock nd->queue->xmit_lock to protect single
isdn_net_lp_busy(). This can fix above lockdep warnings.

Subject: e1000e: reset the PHY on 82577/82578 when going to Sx

The PHY on 82577/82578 parts needs a soft reset when transitioning to Sx
state in order for the PHY write which disables gigabit speed to take
effect.  Gigabit speed must be disabled in order for the PHY writes to
registers on page 800 (the wakeup control registers) to work as expected
otherwise the system might not wake via WoL.

Subject: net: use WARN() for the WARN_ON in commit b6b39e8f3fbbb

Commit b6b39e8f3fbbb (tcp: Try to catch MSG_PEEK bug) added a printk()
to the WARN_ON() that's in tcp.c. This patch changes this combination
to WARN(); the advantage of WARN() is that the printk message shows up
inside the message, so that kerneloops.org will collect the message.

In addition, this gets rid of an extra if() statement.

Subject: perf events: Fix swevent hrtimer sampling by keeping track of
 remaining time when enabling/disabling swevent hrtimers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Make the hrtimer based events work for sysprof.

Whenever a swevent is scheduled out, the hrtimer is canceled.
When it is scheduled back in, the timer is restarted. This
happens every scheduler tick, which means the timer never
expired because it was getting repeatedly restarted over and
over with the same period.

To fix that, save the remaining time when disabling; when
reenabling, use that saved time as the period instead of the
user-specified sampling period.

Also, move the starting and stopping of the hrtimers to helper
functions instead of duplicating the code.

Subject: x86: Remove STACKPROTECTOR_ALL

STACKPROTECTOR_ALL has a really high overhead (runtime and stack
footprint) and is not really worth it protection wise (the
normal STACKPROTECTOR is in effect for all functions with
buffers already), so lets just remove the option entirely.

Subject: nfs: Panic when commit fails

Actually pass the NFS_FILE_SYNC option to the server to avoid a
Panic in nfs_direct_write_complete() when a commit fails.

At the end of an nfs write, if the nfs commit fails, all the writes
will be rescheduled.  They are supposed to be rescheduled as NFS_FILE_SYNC
writes, but the rpc_task structure is not completely intialized and so
the option is not passed.  When the rescheduled writes complete, the
return indicates that they are NFS_UNSTABLE and we try to do another
commit.  This leads to a Panic because the commit data structure pointer
was set to null in the initial (failed) commit attempt.

From 52567b03ca38b6e556ced450d64dba8d66e23b0e Mon Sep 17 00:00:00 2001
From: Trond Myklebust <Trond.Myklebust@netapp.com>
Date: Fri, 23 Oct 2009 14:46:42 -0400
Subject: NFSv4: Fix a bug when the server returns NFS4ERR_RESOURCE

RFC 3530 states that when we recieve the error NFS4ERR_RESOURCE, we are not
supposed to bump the sequence number on OPEN, LOCK, LOCKU, CLOSE, etc
operations. The problem is that we map that error into EREMOTEIO in the XDR
layer, and so the NFSv4 middle-layer routines like seqid_mutating_err(),
and nfs_increment_seqid() don't recognise it.

The fix is to defer the mapping until after the middle layers have
processed the error.

Subject: sched: Strengthen buddies and mitigate buddy induced latencies

This patch restores the effectiveness of LAST_BUDDY in preventing
pgsql+oltp from collapsing due to wakeup preemption. It also
switches LAST_BUDDY to exclusively do what it does best, namely
mitigate the effects of aggressive wakeup preemption, which
improves vmark throughput markedly, and restores mysql+oltp
scalability.

Since buddies are about scalability, enable them beginning at the
point where we begin expanding sched_latency, namely
sched_nr_latency. Previously, buddies were cleared aggressively,
which seriously reduced their effectiveness. Not clearing
aggressively however, produces a small drop in mysql+oltp
throughput immediately after peak, indicating that LAST_BUDDY is
actually doing some harm. This is right at the point where X on the
desktop in competition with another load wants low latency service.
Ergo, do not enable until we need to scale.

To mitigate latency induced by buddies, or by a task just missing
wakeup preemption, check latency at tick time.

Last hunk prevents buddies from stymieing BALANCE_NEWIDLE via
CACHE_HOT_BUDDY.

Supporting performance tests:

 tipx  = NO_GENTLE_FAIR_SLEEPERS NEXT_BUDDY granularity knobs = 31 knobs + 31 buddies

Instead of directly updating filp->f_pos we should update the *ppos
argument. The filp->f_pos gets updated within the file_pos_write()
function called from sys_write().

Subject: tracing: Fix trace_seq_printf() return value

trace_seq_printf() return value is a little ambiguous. It
currently returns the length of the space available in the
buffer. printf usually returns the amount written. This is not
adequate here, because:

  trace_seq_printf(s, "");

is perfectly legal, and returning 0 would indicate that it
failed.

We can always see the amount written by looking at the before
and after values of s->len. This is not quite the same use as
printf. We only care if the string was successfully written to
the buffer or not.

Make trace_seq_printf() return 0 if the trace oversizes the
buffer's free space, 1 otherwise.

Subject: hwmon: (dme1737) No vid attributes for SCH311x

The SCH311x chips do not have VID inputs, so the cpu0_vid and vrm
attributes shouldn't be created for them.

This fixes lm-sensors ticket #2353:

Subject: hwmon: (it87) Fix VID reading on IT8718F/IT8720F

Comparing apples to bananas doesn't seem right. Consistently use the
chips enum for chip type comparisons, to avoid such bugs in the
future.

The bug has been there since support for the IT8718F was added, so
VID never worked for this chip nor for the similar IT8720F.

Subject: block: silently error unsupported empty barriers too

With 2.6.32-rc5 in a KVM guest using dm and virtio_blk, we see the
following errors:

  end_request: I/O error, dev vda, sector 0
  end_request: I/O error, dev vda, sector 0

The errors go away if dm stops submitting empty barriers, by reverting:

  commit 52b1fd5a27c625c78373e024bf570af3c9d44a79
  Author: Mikulas Patocka <mpatocka@redhat.com>
    dm: send empty barriers to targets in dm_flush

We should silently error all barriers, even empty barriers, on devices
like virtio_blk which don't support them.

Subject: r8169: fix Ethernet Hangup for RTL8110SC rev d

The 8110SC rev d chip on our board shows a regression which the 8110SB chip
did not have. When inbound traffic is overflowing the receive descriptor queue,
"holes" in the ring buffer may occur which lead to a hangup until the buffer
is filled again. The packets are than completely processed, but the ring
remains porous and no packets are processed until the next overflow. Setting
the interface down and up can fix the problem temporary from userspace.

For some reason we don't know, this behaviour is not occuring if the RxVlan
bit for hardware VLAN untagging is set. There is another "Work around for
AMD plateform" in the current code which checks the VLAN status
word in receive descriptors, but does never come to effect when hardware
VLAN support is enabled. We assume that this is a bug in the chip.

The following patch fixes the problem. Without the patch we could reproduce
the hang within minutes (given other devices also generating lots of
interrupts), without we couldn't reproduce within a few days of long term
testing.

This version contains minor style adjustments and is sent with mutt which
will hopefully not destroy the formatting again.

Subject: pktgen: Dont leak kernel memory

While playing with pktgen, I realized IP ID was not filled and a
random value was taken, possibly leaking 2 bytes of kernel memory.

We can use an increasing ID, this can help diagnostics anyway.

Also clear packet payload, instead of leaking kernel memory.

Subject: ARM: Fix signal restart issues with NX and OABI compat

The signal restarting code was placed on the user stack when OABI
compatibility is enabled.  Unfortunately, with an EABI NX executable,
this results in an attempt to run code from the non-executable stack,
which segfaults the application.

Fix this by placing the code in the vectors page, along side the
signal return code, and directing the application to that code.

Subject: perf tools: Fix compatibility with libelf 0.8 and autodetect

The Makefile now automatically defines LIBELF_NO_MMAP when
libelf 0.8.x is detected. libelf 0.8 is still maintained and
some distributions such as Arch Linux use it instead of
elfutils.

We were using GFP_DMA for masks other than 0xffffffff, which is
wrong when some masks are initialized to 0xffffffffffffffff.
This caused such masks to obtain memory from the precious DMA
pool.

Subject: sh: Check for return_to_handler when unwinding the stack

When CONFIG_FUNCTION_GRAPH_TRACER is enabled the function graph tracer
may patch return addresses on the stack with the address of
return_to_handler(). This really confuses the DWARF unwinder because it
will try find the caller of return_to_handler(), not the caller of the
real return address.

So teach the DWARF unwinder how to find the real return address whenever
it encounters return_to_handler().

This patch does not cope very well when multiple return addresses on the
stack have been patched. To make it work properly it would require state
to track how many return_to_handler()'s have been seen so that we'd know
where to look in current->curr_ret_stack[]. So for now, instead of
trying to handle this, just moan if more than one return address on the
stack has been patched.

Subject: drm/radeon/kms: fix cs parser tex bit 11 check

The problem boils down to the order when the bit11
of the texture size is or'ed to the original width.
In the end each mipmap level has the same width or
height because of that 11 bit is ored to the scaled
down lod with and thus blows up the size again to the
full size or more due to the power of two rounding
afterwards.

The attached patch changes this order so that the
texture sizes are computed correct. Also the on error
the yet missing inputs to the size computation are
printed which helped me to find out where it really breaks.

Subject: drm/radeon/kms/r7xx: add regs for 40 bit CUR/GRPH addresses

The *_HIGH regs are reversed. The secondary ones are in the
primary block and vice versa.

We currently only use a 32 bit internal address, so these are
0 for now.

Subject: drm/radeon/kms/atom: add support for spread spectrum (v2)

Spread spectrum is a periodic disturbance added
to the feedback divider to change the pixel clock
periodically to reduce interference.

Only enabled on LVDS.

v2: add support for r4xx and fix DCE 3

Subject: perf tools: Remove -Wcast-align

The present use of -Wcast-align causes the build to blow up on
SH due to generating a "cast increases required alignment of
target type" error on each invocation of list_for_each_entry().

It seems that this was previously reported and killed off in the
ia64 support patch, but nothing seems to have happened with
that. Presumably the same problem still remains there, too.

Subject: x86: Side-step lguest problem by only building cmpxchg8b_emu for
 pre-Pentium

Commit 79e1dd05d1a22 "x86: Provide an alternative() based
cmpxchg64()" broke lguest, even on systems which have cmpxchg8b
support.  The emulation code gets used until alternatives get
run, but it contains native instructions, not their paravirt
alternatives.

The simplest fix is to turn this code off except for 386 and 486
builds.

Subject: x86: crash_dump: Fix non-pae kdump kernel memory accesses

Non-PAE 32-bit dump kernels may wrap an address around 4G and
poke unwanted space. ptes there are 32-bit long, and since
pfn << PAGE_SIZE may exceed this limit, high pfn bits are
cropped and wrong address mapped by kmap_atomic_pfn in
copy_oldmem_page.

Don't allow this behavior in non-PAE kdump kernels by checking
pfns passed into copy_oldmem_page. In the case of failure,
userspace process gets EFAULT.

commit 0762b8bde9729f10f8e6249809660ff2ec3ad735
(from 14 months ago) introduced a use-after-free bug which has just
recently started manifesting in my md testing.
I tried git bisect to find out what caused the bug to start
manifesting, and it could have been the recent change to
blk_unregister_queue (48c0d4d4c04) but the results were inconclusive.

This patch certainly fixes my symptoms and looks correct as the two
calls are now in the same order as elsewhere in that function.

Restoring %ebp after the call to audit_syscall_exit() is not
only unnecessary (because the register didn't get clobbered),
but in the sysenter case wasn't even doing the right thing: It
loaded %ebp from a location below the top of stack (RBP <
ARGOFFSET), i.e. arbitrary kernel data got passed back to user
mode in the register.

Subject: sh: Fix hugetlbfs dependencies for SH-3 && MMU configurations.

The hugetlb dependencies presently depend on SUPERH && MMU while the
hugetlb page size definitions depend on CPU_SH4 or CPU_SH5. This
unfortunately allows SH-3 + MMU configurations to enable hugetlbfs
without a corresponding HPAGE_SHIFT definition, resulting in the build
blowing up.

As SH-3 doesn't support variable page sizes, we tighten up the
dependenies a bit to prevent hugetlbfs from being enabled. These days
we also have a shiny new SYS_SUPPORTS_HUGETLBFS, so switch to using
that rather than adding to the list of corner cases in fs/Kconfig.

Subject: igb: fix memory leak when setting ring size while interface is down

Changing ring sizes while the interface was down was causing a double
allocation of the receive and transmit rings.  This issue is amplified when
there are multiple rings enabled.  To prevent this we need to add an
additional check which will just update the ring counts when the interface
is not up and skip the allocation steps.

Subject: e1000e: increase swflag acquisition timeout for ICHx/PCH

In some conditions (e.g. when AMT is enabled on the system), it is possible
to take an extended period of time to for the driver to acquire the sw/fw/hw
hardware semaphore used to protect against concurrent access of a shared
resource (e.g. PHY registers).  This could cause PHY registers to not get
configured properly resulting in link issues.

Subject: e1000e: 82577/82578 requires a different method to configure LPLU

Unlike previous ICHx-based parts, the PCH-based parts (82577/82578) require
LPLU (Low Power Link Up, or "reverse auto-negotiation") to be configured in
the PHY rather than the MAC.

Subject: e1000e: separate mutex usage between NVM and PHY/CSR register for
 ICHx/PCH

Accesses to NVM and PHY/CSR registers on ICHx/PCH-based parts are protected
from concurrent accesses with a mutex that is acquired when the access is
initiated and released when the access has completed.  However, the two
types of accesses should not be protected by the same mutex because the
driver may have to access the NVM while already holding the mutex over
several consecutive PHY/CSR accesses which would result in livelock.

Subject: e1000e: allow for swflag to be held over consecutive PHY accesses

PCH-based parts (82577/82578) and some ICH8-based parts (82566) need to
hold the swflag (sw/fw/hw hardware semaphore) over consecutive PHY accesses
in order to perform sw-driven PHY configuration during initialization to
workaround known hardware issues (see follow-on patch).  This patch
provides new PHY read/write functions (and function pointers) that will
allow accessing the PHY registers assuming the swflag has already been
acquired.  The actual PHY register access code has moved into helper
functions that are called with a flag indicating whether or not the swflag
has already been acquired and acquires/releases it if not.

The functions called from within the updated PHY access functions had to be
updated to assume the swflag was already acquired, and other functions that
called those functions were also updated to acquire/release the swflag.

From: Michal Ostrowski <mostrows@gmail.com>
Date: Mon, 26 Oct 2009 16:23:20 -0700
Subject: PPPoE: Fix flush/close races.

Be more careful about the state of pointers during tear-down.
The "pppoe_dev" field can only be looked at safely while holding socket locks.
This subsequently allows for the flush_lock to be killed.

We depend on the PPPOX_CONNECTED state to tell us that that those fields are
valid, so whoever clears that state (pppox_unbind_sock()) is responsible for
the dev_put() call.

We also have to ensure that we delete_item() on all sockets before they are
cleaned up.

The need for these changes has been exposed by scenarios wherein namespace
bindings of ethernet devices change while there are ongoing PPPoE sessions,
which resulted in oopses due to unusual socket connection termination paths,
exposing these issues.

Subject: powerpc/perf_events: Fix priority of MSR HV vs PR bits

The architecture defines that if MSR PR is set we are in problem state
irrespective of the HV bit.  This fixes perf events to reflect this.

Also, on bare metal systems, samples taken in Linux will now be reported
as kernel rather than hypervisor.

Subject: powerpc/iseries: Remove compiler version dependent hack

The creation of the flattened device tree depended on the compiler
putting the constant strings for an object in a section with a
particular name.  This was changed with recent compilers.  Do this
explicitly instead.

Without this patch, iseries kernels may silently not boot when built with
some compilers.

From fafbe983d9fe723caa4ee1899663ed4c2d19ed3b Mon Sep 17 00:00:00 2001
From: Kumar Gala <galak@kernel.crashing.org>

Subject: powerpc: Add a Book-3E 64-bit defconfig

This defconfig's purpose at this time is to help catch compile errors
between Book-3S and Book-3E support in ppc64.  It is based on the
ppc64_defconfig with some things disabled that we dont support on
Book-3E right now (hugetlbfs, slices, etc.)

Date: Mon, 26 Oct 2009 19:41:17 +0000
Subject: powerpc/ppc64: Use preempt_schedule_irq instead of preempt_schedule

Based on an original patch by Valentine Barshak <vbarshak@ru.mvista.com>

Use preempt_schedule_irq to prevent infinite irq-entry and
eventual stack overflow problems with fast-paced IRQ sources.

This kind of problems has been observed on the PASemi Electra IDE
controller. We have to make sure we are soft-disabled before calling
preempt_schedule_irq and hard disable interrupts after that
to avoid unrecoverable exceptions.

This patch also moves the "clrrdi r9,r1,THREAD_SHIFT" out of
the #ifdef CONFIG_PPC_BOOK3E scope, since r9 is clobbered
and has to be restored in both cases.

Subject: x86: Make EFI RTC function depend on 32bit again

The EFI RTC functions are only available on 32 bit. commit 7bd867df
(x86: Move get/set_wallclock to x86_platform_ops) removed the 32bit
dependency which leads to boot crashes on 64bit EFI systems.

Add the dependency back.

This reverts commit 308cf8e13f42f476dfd6552aeff58fdc0788e566.  This
patch had trouble with transparent bridges, among other things.  A more
readable and correct version should land in 2.6.33.

Subject: b43: Fix Bugzilla #14181 and the bug from the previous 'fix'

"b43: Fix PPC crash in rfkill polling on unload" fixed the bug reported
in Bugzilla No. 14181; however, it introduced a new bug. Whenever the
radio switch was turned off, it was necessary to unload and reload
the driver for it to recognize the switch again.

This patch fixes both the original bug in #14181 and the bug introduced by
the previous patch. It must be stated, however, that if there is a BCM4306/3
with an rfkill switch (not yet proven), then the driver will need an
unload/reload cycle to turn the device back on.

Subject: mac80211: fix ibss joining

Recent commit "mac80211: fix logic error ibss merge bssid check" fixed
joining of ibss cell when static bssid is provided. In this case
ifibss->bssid is set before the cell is joined and comparing that address
to a bss should thus always succeed. Unfortunately this change broke the
other case of joining a ibss cell without providing a static bssid where
the value of ifibss->bssid is not set before the cell is joined.

Since ifibss->bssid may be set before or after joining the cell we do not
learn anything by comparing it to a known bss. Remove this check.

Subject: mac80211: keep auth state when assoc fails

When association fails, we should stay authenticated,
which in mac80211 is represented by the existence of
the mlme work struct, so we cannot free that, instead
we need to just set it to idle.

Subject: cfg80211: sme: deauthenticate on assoc failure

When the in-kernel SME gets an association failure from
the AP we don't deauthenticate, and thus get into a very
confused state which will lead to warnings later on. Fix
this by actually deauthenticating when the AP indicates
an association failure.

Subject: mac80211: fix for incorrect sequence number on hostapd injected
 frames
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When hostapd injects a frame, e.g. an authentication or association
response, mac80211 looks for a suitable access point virtual interface
to associate the frame with based on its source address. This makes it
possible e.g. to correctly assign sequence numbers to the frames.

A small typo in the ethernet address comparison statement caused a
failure to find a suitable ap interface. Sequence numbers on such
frames where therefore left unassigned causing some clients
(especially windows-based 11b/g clients) to reject them and fail to
authenticate or associate with the access point. This patch fixes the
typo in the address comparison statement.

xen_setup_stackprotector() ends up trying to set page protections,
so we need to have vm_mmu_ops set up before trying to do so.
Failing to do so causes an early boot crash.

[ Impact: Fix early crash under Xen. ]

Since we register all radeon devices, and the arbiter only cares about
VGA class ones, we will fail to startup on display controller class devices.
We don't gain anything by using the return value here.

this helps kms on sparc64 get started.

Sometimes we will get the incorrect display modeline when parsing the detailed
timing in EDID. For example:
   >hsync/vsync width is zero
   >sync is beyond the blank.

So add the basic check for the detailed timing in EDID to avoid the incorrect
display modeline.

Subject: drm/radeon/kms/atom: loosen pll min output limits

Limiting the pll output range is a good thing generally as
it limits the number of possible pll combinations for a given
frequency presumably to the ones that work best on each card.
That's why the limits are in the bios tables. However, certain
duallink DVI monitors seem to like pll combinations that would
be limited by this at least on pre-DCE 3.0 r6xx hardware.  This
might need to be adjusted per family or per clock range in the
future.

See fdo bug 24727.

Subject: drm/radeon/kms/atom: Make card_info per device

Make the struct card_info, which is a per struct radeon_device dataset, a
struct member of the radeon device instead of a static per kernel module
value. This should avoid potential problems with two radeon cards installed in
one system.

we do not do this. This causes guest data corruption and crashes
with vhost since net core can requeue the skb or free it without
it being taken off the list.

This patch fixes this by queueing the skb after successful
transmit.

Subject: percpu: allow pcpu_alloc() to be called with IRQs off

pcpu_alloc() and pcpu_extend_area_map() perform a series of
spin_lock_irq()/spin_unlock_irq() calls, which make them unsafe
with respect to being called from contexts which have IRQs off.

This patch converts the code to perform save/restore of flags instead,
making pcpu_alloc() (or __alloc_percpu() respectively) to be called
from early kernel startup stage, where IRQs are off.

This is needed for proper initialization of per-cpu rq_weight data from
sched_init().

tj: added comment explaining why irqsave/restore is used in alloc path.

Subject: sched: move rq_weight data array out of .percpu

Commit 34d76c41 introduced percpu array update_shares_data, size of which
being proportional to NR_CPUS. Unfortunately this blows up ia64 for large
NR_CPUS configuration, as ia64 allows only 64k for .percpu section.

Fix this by allocating this array dynamically and keep only pointer to it
percpu.

The per-cpu handling doesn't impose significant performance penalty on
potentially contented path in tg_shares_up().

Subject: ACPI: clean up video.c boundary checks and types

proc.c and video.c are a bit sloppy around types and style,
confusing gcc for a new feature that'll be in 2.6.33 and will
cause a warning on the current code.

This patch changes

if  (foo + 1 > sizeof bar)

into

if (foo >= sizeof(bar))

which is more kernel-style.

it also changes a variable in proc.c to unsigned; it gets assigned
a value from an unsigned type, and is then only compared for > not
for negative, so using unsigned is just outright the right type

The S3C64XX DMA implementation will work a lot better with the ability
to enqueue circular buffers as the hardware can do it's own linked-list
management.

Add a function s3c_dma_has_circular() to show that the system can do this
and a flag for the channel.

Update the s3c24xx/s3c64xx I2S DMA code to deal with this.

Fix the link errors if cpu-frequency support is enabled on s3c2410 systems
but there is no CONFIG_S3C2410_IOTIMING set. Fix this by ensuring the
relevant symbols are defined NULL if the code is not being built in.

Fixes the following error:

Subject: futex: Fix spurious wakeup for requeue_pi really

The requeue_pi path doesn't use unqueue_me() (and the racy lock_ptr ==
NULL test) nor does it use the wake_list of futex_wake() which where
the reason for commit 41890f2 (futex: Handle spurious wake up)

See debugging discussing on LKML Message-ID: <4AD4080C.20703@us.ibm.com>

The changes in this fix to the wait_requeue_pi path were considered to
be a likely unecessary, but harmless safety net. But it turns out that
due to the fact that for unknown $@#!*( reasons EWOULDBLOCK is defined
as EAGAIN we built an endless loop in the code path which returns
correctly EWOULDBLOCK.

Spurious wakeups in wait_requeue_pi code path are unlikely so we do
the easy solution and return EWOULDBLOCK^WEAGAIN to user space and let
it deal with the spurious wakeup.

Subject: virtio-pci: fix per-vq MSI-X request logic

Commit f68d24082e22ccee3077d11aeb6dc5354f0ca7f1
in 2.6.32-rc1 broke requesting IRQs for per-VQ MSI-X vectors:
- vector number was used instead of the vector itself
- we try to request an IRQ for VQ which does not
  have a callback handler

This is a regression that causes warnings in kernel log,
potentially lower performance as we need to scan vq list,
and might cause system failure if the interrupt
requested is in fact needed by another system.

This was not noticed earlier because in most cases
we were falling back on shared interrupt for all vqs.

The warnings often look like this:

virtio-pci 0000:00:03.0: irq 26 for MSI/MSI-X
virtio-pci 0000:00:03.0: irq 27 for MSI/MSI-X
virtio-pci 0000:00:03.0: irq 28 for MSI/MSI-X
IRQ handler type mismatch for IRQ 1
current handler: i8042

Subject: virtio: order used ring after used index read

On SMP guests, reads from the ring might bypass used index reads. This
causes guest crashes because host writes to used index to signal ring
data readiness.  Fix this by inserting rmb before used ring reads.

Subject: param: fix lots of bugs with writing charp params from sysfs, by
 leaking mem.

e180a6b7759a "param: fix charp parameters set via sysfs" fixed the case
where charp parameters written via sysfs were freed, leaving drivers
accessing random memory.

Unfortunately, storing a flag in the kparam struct was a bad idea: it's
rodata so setting it causes an oops on some archs.  But that's not all:

1) module_param_array() on charp doesn't work reliably, since we use an
   uninitialized temporary struct kernel_param.
2) there's a fundamental race if a module uses this parameter and then
   it's changed: they will still access the old, freed, memory.

The simplest fix (ie. for 2.6.32) is to never free the memory.  This
prevents all these problems, at cost of a memory leak.  In practice, there
are only 18 places where a charp is writable via sysfs, and all are
root-only writable.

Subject: param: fix setting arrays of bool

We create a dummy struct kernel_param on the stack for parsing each
array element, but we didn't initialize the flags word.  This matters
for arrays of type "bool", where the flag indicates if it really is
an array of bools or unsigned int (old-style).

Subject: bonding: fix a race condition in calls to slave MII ioctls

In mii monitor mode, bond_check_dev_link() calls the the ioctl
handler of slave devices. It stores the ndo_do_ioctl function
pointer to a static (!) ioctl variable and later uses it to call the
handler with the IOCTL macro.

If another thread executes bond_check_dev_link() at the same time
(even with a different bond, which none of the locks prevent), a
race condition occurs. If the two racing slaves have different
drivers, this may result in one driver's ioctl handler being
called with a pointer to a net_device controlled with a different
driver, resulting in unpredictable breakage.

Unless I am overlooking something, the "static" must be a
copy'n'paste error (?).

Subject: AF_RAW: Augment raw_send_hdrinc to expand skb to fit iphdr->ihl (v2)

Augment raw_send_hdrinc to correct for incorrect ip header length values

A series of oopses was reported to me recently.  Apparently when using AF_RAW
sockets to send data to peers that were reachable via ipsec encapsulation,
people could panic or BUG halt their systems.

I've tracked the problem down to user space sending an invalid ip header over an
AF_RAW socket with IP_HDRINCL set to 1.

Basically what happens is that userspace sends down an ip frame that includes
only the header (no data), but sets the ip header ihl value to a large number,
one that is larger than the total amount of data passed to the sendmsg call.  In
raw_send_hdrincl, we allocate an skb based on the size of the data in the msghdr
that was passed in, but assume the data is all valid.  Later during ipsec
encapsulation, xfrm4_tranport_output moves the entire frame back in the skbuff
to provide headroom for the ipsec headers.  During this operation, the
skb->transport_header is repointed to a spot computed by
skb->network_header + the ip header length (ihl).  Since so little data was
passed in relative to the value of ihl provided by the raw socket, we point
transport header to an unknown location, resulting in various crashes.

This fix for this is pretty straightforward, simply validate the value of of
iph->ihl when sending over a raw socket.  If (iph->ihl*4U) > user data buffer
size, drop the frame and return -EINVAL.  I just confirmed this fixes the
reported crashes.

I found that the current version of drivers/net/usb/dm9601.c can be used to
successfully drive a low-power, low-cost network adapter with USB ID
0a46:9000, based on a DM9000E chipset. As no device with this ID is yet
present in the kernel, I have created a patch that adds support for the device
to the dm9601 driver.

Created and tested against linux-2.6.32-rc5.

Subject: ide: Serialize CMD643 and CMD646 to fix a hardware bug with SSD

CMD646 corrupts data on concurrent transfers on both channels when IDE SSD is
connected to one of the channels.

Setup that demonstrates this hardware bug: Ultra 5, onboard CMD646, rev 3.
/dev/hda is 8GB Seagate ST38410A in MWDMA2
/dev/hdd is 32GB SSD SiliconHardDisk in MWDMA2

- When reading /dev/hdd (for example with dd or fsck), reads from /dev/hda
  are corrupted, there are twiddled single bits 1->0 and some full 32-bit
  words corrupted, sometimes commands fail (which switches /dev/hda to
  PIO mode but the corruptions happen even in PIO).
- Reads from /dev/hdd don't seem to be corrupted (i.e. fsck passes fine).
- When I connected normal rotating harddisk to /dev/hdd, there was no
  corruption, so the corruption is something specific to SSD.
- I tried the same setup on a PCI card with CMD649 and saw no corruption.

This patch serializes the operation for CMD646 and 643 (I didn't test
CMD643 but it may have the same hw bug too because it's earlier design).
CMD649 is good. I don't know anything about CMD 648.

Currently PACKET_TX_RING forces certain amount of every frame to remain
unused. This probably originates from an early version of the
PACKET_TX_RING patch that in fact used the extra space when the (since
removed) CONFIG_PACKET_MMAP_ZERO_COPY option was enabled. The current
code does not make any use of this extra space.

This patch removes the extra space reservation and lets userspace make
use of the full frame size.

Subject: backing-dev: ensure that a removed bdi no longer has super_block
 referencing it

When the bdi is being removed, we have to ensure that no super_blocks
currently have that cached in sb->s_bdi. Normally this is ensured by
the sb having a longer life span than the bdi, but if the device is
suddenly yanked, we have to kill this reference. sb->s_bdi is pointed
to freed memory at that point.

This fixes a problem with sync(1) hanging when a USB stick is pulled
without cleanly umounting it first.

Subject: [S390] smp: fix prefix handling of offlined cpus

Offlined cpus still have valid prefix register contents. Dumpers
will store the register contents of a cpu to the location where its
prefix register points to.
For offlined cpus the area (lowcore) has been freed and the dumper
would write the uninteresting contents of the offline cpu to a memory
location which might be in use by some other component and destroy
valueable information.
To fix this set the prefix register of offline cpus to absolute
address zero again. This prevents the current dumpers to write to
random memory locations.

Subject: [S390] call home: fix string length handling

After copying uts->nodename to the static nodename array the static
version isn't necessarily zero termininated, since the size of the
array is one byte too short.
Afterwards doing strncat(data, nodename, strlen(nodename)); may copy
an arbitrary large amount of bytes.
Fix this by getting rid of the static array and using strncat with
proper length limit.

According to the architecture a cpu must not necessarily enter stopped
state after completion of a sigp instruction with "stop" order code.
So remove the BUG() statement after self sending sigp stop to avoid
that it ever gets reached.
Also add a sigp busy check to make sure that the order gets delivered.

Subject: [S390] smp: fix sigp sense handling

sigp sense only returns the status of a cpu if it is non zero. If the
status of the sensed cpu is all zeros condition code 0 (accpeted) is
set and no status bits are returned.
The current code however assumes that a status was returned and tests
bits in it. This means uninitalized data is accessed with random
results.
Worst case is that the code that checks if cpu is offline on cpu
hotplug assumes that the target cpu is offline while it is still
running. This leads potentially to memory corruption since resources
that are still needed by the target cpu will be freed and could be
resused while still in use.

Subject: cpufreq: add cpufreq_get() stub for CONFIG_CPU_FREQ=n

When CONFIG_CPU_FREQ is disabled, cpufreq_get() needs a stub.  Used by kvm
(although it looks like a bit of the kvm code could be omitted when
CONFIG_CPU_FREQ is disabled).

arch/x86/built-in.o: In function `kvm_arch_init':
(.text+0x10de7): undefined reference to `cpufreq_get'

(Needed in linux-next's KVM tree, but it's correct in 2.6.32).

Subject: hwpoison: fix oops on ksm pages

Memory failure on a KSM page currently oopses on its NULL anon_vma in
page_lock_anon_vma(): that may not be much worse than the consequence of
ignoring it, but it is better to be consistent with how ZERO_PAGE and
hugetlb pages and other awkward cases are treated.  Just skip it.

We could fix it for 2.6.32 at the KSM end, by putting a dummy anon_vma
pointer in there; but that would get harder next time, when KSM will put a
pointer to something else there (and I'm not currently planning to do any
work to open that up to memory_failure).  So I would prefer this simple
PageKsm test, until the other exceptions are handled.

Given such a long name, the kB count in /proc/meminfo's HardwareCorrupted
line is being shown too far right (it does align with x86_64's VmallocChunk
above, but I hope nobody will ever have that much corrupted!).  Align it.

Subject: connector: fix regression introduced by sid connector

Since commit 02b51df1b07b4e9ca823c89284e704cadb323cd1 (proc connector: add
event for process becoming session leader) we have the following warning:

 [<00000041616cb266>] 0x41616cb266

The warning is
--->    WARN_ON_ONCE(in_irq() || irqs_disabled());

The network code must not be called with disabled interrupts but
sys_setsid holds the tasklist_lock with spinlock_irq while calling the
connector.

After a discussion we agreed that we can move proc_sid_connector from
__set_special_pids to sys_setsid.

We also agreed that it is sufficient to change the check from
task_session(curr) != pid into err > 0, since if we don't change the
session, this means we were already the leader and return -EPERM.

One last thing:
There is also daemonize(), and some people might want to get a
notification in that case. Since daemonize() is only needed if a user
space does kernel_thread this does not look important (and there seems
to be no consensus if this connector should be called in daemonize). If
we really want this, we can add proc_sid_connector to daemonize() in an
additional patch (Scott?)

cgroup_write_X64() and cgroup_write_string() ignore the return value of
strstrip().  it makes small inconsistent behavior.

 # cat memory.swappiness
 60
 # echo "59 " > memory.swappiness
 # cat memory.swappiness
 59
 # echo " 58" > memory.swappiness
 bash: echo: write error: Invalid argument

Subject: strstrip(): mark as as must_check

strstrip() can return a modified value of its input argument, when
removing elading whitesapce.  So it is surely bug for this function's
return value to be ignored.  The caller is probably going to use the
incorrect original pointer.

So mark it __must_check to prevent this frm happening (as it has before).

Subject: hfsplus: refuse to mount volumes larger than 2TB

As found in <http://bugs.debian.org/550010>, hfsplus is using type u32
rather than sector_t for some sector number calculations.

In particular, hfsplus_get_block() does:

        u32 ablock, dblock, mask;
...
        map_bh(bh_result, sb, (dblock << HFSPLUS_SB(sb).fs_shift) + HFSPLUS_SB(sb).blockoffset + (iblock & mask));

I am not confident that I can find and fix all cases where a sector number
may be truncated.  For now, avoid data loss by refusing to mount HFS+
volumes with more than 2^32 sectors (2TB).

        mm: oom analysis: add buffer cache information to show_free_areas()

show_free_areas() is called during page allocation failures, and page
allocation failures can occur in any calling context.

But nr_blockdev_pages() takes VFS locks which should not be taken from
hard IRQ context (at least).  The result is lockdep warnings (and
deadlockability) during page allocation failures.

Subject: vmscan: limit VM_EXEC protection to file pages

It is possible to have !Anon but SwapBacked pages, and some apps could
create huge number of such pages with MAP_SHARED|MAP_ANONYMOUS.  These
pages go into the ANON lru list, and hence shall not be protected: we only
care mapped executable files.  Failing to do so may trigger OOM.

Subject: hfs: fix oops on mount with corrupted btree extent records

A particular fsfuzzer run caused an hfs file system to crash on mount.
This is due to a corrupted MDB extent record causing a miscalculation of
HFS_I(inode)->first_blocks for the extent tree.  If the extent records are
zereod out, it won't trigger the first_blocks special case.  Instead it
falls through to the extent code which we're still in the middle of
initializing.

This patch catches the 0 size extent records, reports the corruption, and
fails the mount.

Subject: vmscan: order evictable rescue in LRU putback

Isolators putting a page back to the LRU do not hold the page lock, and if
the page is mlocked, another thread might munlock it concurrently.

Expecting this, the putback code re-checks the evictability of a page when
it just moved it to the unevictable list in order to correct its decision.

The problem, however, is that ordering is not garuanteed between setting
PG_lru when moving the page to the list and checking PG_mlocked
afterwards:

	#0:				#1

	spin_lock()
					if (TestClearPageMlocked())
					  if (PageLRU())
					    move to evictable list
	SetPageLRU()
	spin_unlock()
	if (!PageMlocked())
	  move to evictable list

The PageMlocked() check may get reordered before SetPageLRU() in #0,
resulting in #0 not moving the still mlocked page, and in #1 failing to
isolate and move the page as well.  The page is now stranded on the
unevictable list.

The race condition is very unlikely.  The consequence currently is one
page falling off the reclaim grid and eventually getting freed with
PG_unevictable set, which triggers a warning in the page allocator.

TestClearPageMlocked() in #1 already provides full memory barrier
semantics.

This patch adds an explicit full barrier to force ordering between
SetPageLRU() and PageMlocked() so that either one of the competitors
rescues the page.

is_power_of_2() appears not to be constant enough for BUILD_BUG_ON()

Subject: twl4030-gpio: remove __devexit markings from remove func

The gpio_twl4030_probe() function calls gpio_twl4030_remove(), and the
former has __devinit, so the latter cannot use __devexit.  Otherwise we
hit the section mismatch warning:

WARNING: drivers/gpio/built-in.o(.devinit.text+0x71a): Section mismatch
	in reference from the function _gpio_twl4030_probe() to the function
	.devexit.text:_gpio_twl4030_remove()
The function __devinit _gpio_twl4030_probe() references a function
	__devexit _gpio_twl4030_remove().
This is often seen when error handling in the init function uses
	functionality in the exit path.
The fix is often to remove the __devexit annotation of
	_gpio_twl4030_remove() so it may be used outside an exit section.

Subject: edac: i5400 fix csrow mapping

The i5400 EDAC driver has several bugs with chip-select row computation
which most likely lead to bugs in detailed error reporting.  Attempts to
contact the authors have gone mostly unanswered so I am presenting my diff
here.  I do not subscribe to lkml and would appreciate being kept in the
cc.

The most egregious problem was miscalculating the addresses of MTR
registers after register 0 by assuming they are 32bit rather than 16.
This caused the driver to miss half of the memories.  Most motherboards
tend to have only 8 dimm slots and not 16, so this may not have been
noticed before.

Further, the row calculations multiplied the number of dimms several
times, ultimately ending up with a maximum row of 32.  The chipset only
supports 4 dimms in each of 4 channels, so csrow could not be higher than
4 unless you use a row per-rank with dual-rank dimms.  I opted to
eliminate this behavior as it is confusing to the user and the error
reporting works by slot and not rank.  This gives a much clearer view of
memory by slot and channel in /sys.

Subject: edac: i5100 fix initialization code

Allow csrows to properly initialize when the topology only has active
channels on 2 and 3.  This new check allows proper detection and
initialization in this topology.  Only checking the first mrt that
represented channels 0 and 1 is not sufficient.

I also fixed up the related debug information path.  I can submit as a 2nd
patch if needed.

Currently, sparsemem is only available if EXPERIMENTAL is enabled.
However, it hasn't ever been marked experimental.

It's been about four years since sparsemem was merged, and we have
platforms which depend on it; allow architectures to decide whether
sparsemem should be the default memory model.

Subject: checkpatch: fix false errors due to macro concatenation

The macro concatenation (##) sequence can cause false errors when checking
macro's.  Checkpatch doesn't currently know about the operator.

For example this line,

+ 	entry = (struct ftrace_raw_##call *)raw_data;                   \

is correct but it produces the following error,

ERROR: need consistent spacing around '*' (ctx:WxB)
+       entry = (struct ftrace_raw_##call *)raw_data;\
                                          ^

The line above doesn't have any spacing problems, and if you remove the
macro concatenation sequence checkpatch doesn't give any errors.

Extend identifier handling to include ## concatenation within the
definition of an identifier.

Subject: checkpatch: fix __attribute__ matching

In the following code,

union thread_union init_thread_union
	__attribute__((__section__(".data.init_task"))) =
		{ INIT_THREAD_INFO(init_task) };

There is a non-conforming declaration. It should really be like the
following,

union thread_union init_thread_union
	__attribute__((__section__(".data.init_task"))) = {
		INIT_THREAD_INFO(init_task)
};

However, checkpatch doesn't catch this right now because it doesn't
correctly evaluate the "__attribute__".

It is not at all clear that we care what preceeds an assignment style
attribute when we find the open brace.  Relax the test so we do not need
to check the __attribute__.

Subject: checkpatch: fix false EXPORT_SYMBOL warning

Ingo reported that the following lines triggered a false warning,

static struct lock_class_key rcu_lock_key;
struct lockdep_map rcu_lock_map =
        STATIC_LOCKDEP_MAP_INIT("rcu_read_lock", &rcu_lock_key);
EXPORT_SYMBOL_GPL(rcu_lock_map);

from kernel/rcutree.c , and the false warning looked like this,

WARNING: EXPORT_SYMBOL(foo); should immediately follow its
function/variable
+EXPORT_SYMBOL_GPL(rcu_lock_map);

We actually should be checking the statement before the EXPORT_* for a
mention of the exported object, and complain where it is not there.

Subject: cpuidle: always return with interrupts enabled

In the case where cpuidle_idle_call() returns before changing state due to
a need_resched(), it was returning with IRQs disabled.

The idle path assumes that the platform specific idle code returns with
interrupts enabled (although this too is undocumented AFAICT) and on ARM
we have a WARN_ON(!(irqs_disabled()) when returning from the idle loop, so
the user-visible effects were only a warning since interrupts were
eventually re-enabled later.

On x86, this same problem exists, but there is no WARN_ON() to detect it.
As on ARM, the interrupts are eventually re-enabled, so I'm not sure of
any actual bugs triggered by this.  It's primarily a
correctness/consistency fix.

This patch ensures IRQs are (re)enabled before returning.

I have learned that the 6730b and 6730s have different accelerometer
orientation, and have modified the driver accordingly (diff attached),
while dropping the wild guess for AMD based 6735 having the same
orientation as Intel based 6730 (this is not true for any other related
series/family, thus is not probable for 673x).

Subject: mm: don't call pte_unmap() against an improper pte

There are some places where we do like:

	pte = pte_map();
	do {
		(do break in some conditions)
	} while (pte++, ...);
	pte_unmap(pte - 1);

But if the loop breaks at the first loop, pte_unmap() unmaps invalid pte.

This patch is a fix for this problem.

When PAE is enabled in the kernel configuration the size of

When SPARSEMEM_EXTREME is enabled, memory_present() wants to use bootmem
to allocate data structures.  However, we call memory_present() after
declaring memory to bootmem, but before we've reserved areas.

This leads to sparsemem data structures being overwritten later in the
kernel's initialization (when slab initializes.)

Subject: ARM: Fix errata 411920 workarounds

Errata 411920 indicates that any "invalidate entire instruction cache"
operation can fail if the right conditions are present.  This is not
limited just to those operations in flush.c, but elsewhere.  Place the
workaround in the already existing __flush_icache_all() function
instead.

Subject: ocfs2: return f_fsid info in ocfs2_statfs()

Currently the f_fsid of struct kstatfs returned from ocfs2_statfs() is
undefined (vfs layer fills in 0 as default). Since in some conditions,
f_fsid value might be used in a (f_fsid, ino) pair to uniquely identify
a file, ocfs2 should return a unique defined f_fsid value from
ocfs2_statfs().

Because uuid_str is the same on big or litlle endian machine, it's
endian consistent to use osb->uuid_str to generate f_fsid value.

Subject: e100: e100_phy_init() isolates selected PHY, causes 10 second boot
 delay

A change in how PHYs are electrically isolated caused all PHYs to be
isolated followed by reverting that isolation for the selected PHY.
Unfortunately, isolating the selected PHY for even a short period of
time can result in DHCP negotiation taking more than 10 seconds on certain
embedded configurations delaying boot time as reported by Bernhard Kaindl.
This patch reverts the change to how PHYs are isolated yet still works
around the issue for 82552 needing the selected PHY's BMCR register to
be written after the unused PHYs are isolated.  This code is moved below
the setting of nic->phy ID in order to do the 82552-specific workaround.

Subject: e1000e: config PHY via software after resets

On PCH-based (82577/82578) and some ICH8-based parts (82566) there is an
issue with the hardware automatically configuring the PHY with contents
from the EEPROM after the PHY is reset, so do the configuration by the
driver instead.  This was already similarly done for some 82566 parts in
e1000_phy_hw_reset_ich8lan() but needs to be done after other resets,
so move the PHY configuration code to its own function and call after
all PHY resets.

From 1d5846b9216665d0ae743bf351d0b8fa90c40523 Mon Sep 17 00:00:00 2001
From: Bruce Allan <bruce.w.allan@intel.com>

Subject: e1000e: rework disable K1 at 1000Mbps for 82577/82578

This patch reworks a previous workaround (commit 7d3cabbcc) for an issue
in hardware where noise on the interconnect between the MAC and PHY could
be generated by a lower power mode (K1) at 1000Mbps resulting in bad
packets.  Disable K1 while at 1000 Mbps but keep it enabled for 10/100Mbps
and when the cable is disconnected.  The original version of this
workaround was found to be incomplete.

Fix this by moving 'protocol' inside flags1 bitfield,
and queue_mapping inside flags2 bitfield.

Subject: xfs: free temporary cursor in xfs_dialloc

Commit bd169565993b39b9b4b102cdac8b13e0a259ce2f seems
to have a slight regression where this code path:

    if (!--searchdistance) {
        /*
         * Not in range - save last search
         * location and allocate a new inode
         */
        ...
        goto newino;
    }

doesn't free the temporary cursor (tcur) that got dup'd in
this function.

This leaks an item in the xfs_btree_cur zone, and it's caught
on module unload:

===========================================================
BUG xfs_btree_cur: Objects remaining on kmem_cache_close()
-----------------------------------------------------------

It seems like maybe a single free at the end of the function might
be cleaner, but for now put a del_cursor right in this code block
similar to the handling in the rest of the function.

Subject: xfs: fix xfs_quota remove error

The xfs_quota returns ENOSYS when remove command is executed.
Reproducable with following steps.

    # mount -t xfs -o uquota /dev/sda7 /mnt/mp1
    # xfs_quota -x -c off -c remove
    XFS_QUOTARM: Function not implemented.

The remove command is allowed during quotaoff, but xfs_fs_set_xstate()
checks whether quota is running, and it leads to ENOSYS.

To solve this problem, add a check for X_QUOTARM.

Subject: ALSA: pcsp - Fix nforce workaround

The attached patch fixes the problems introduced in this commit:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=eea0579fc85e64e9f05361d5aacf496fe7a151aa

- Fix nForce workaround by honouring the pointer_update var
- Revert "ns" to u64, as per the hrtimer API
- Revert to the zero-delay timer startup, since I can't reproduce any
  problem with it (please, give me the hint!)

Subject: ALSA: sound: Move dereference after NULL test and drop unnecessary
 NULL tests

In pcm.c, if the NULL test on pcm is needed, then the dereference should be
after the NULL test.

In dummy.c and ali5451.c, the context of the calls to
snd_card_dummy_new_mixer and snd_ali_free_voice show that dummy and pvoice,
respectively cannot be NULL.

A simplified version of the semantic match that detects this problem is as
follows (http://coccinelle.lip6.fr/):

// <smpl>
@match exists@
expression x, E;
identifier fld;
@@

* x->fld
  ... when != \(x = E\|&x\)
* x == NULL

Subject: ALSA: sound/parisc: Move dereference after NULL test

If the NULL test on h is needed in snd_harmony_mixer_init, then the
dereference should be after the NULL test.

Actually, there is a sequence of calls: snd_harmony_create, then
snd_harmony_pcm_init, and then snd_harmony_mixer_init.  snd_harmony_create
initializes h, but may indeed leave it as NULL.  There was no NULL test at
the beginning of snd_harmony_pcm_init, so I have added one.  The NULL test
in snd_harmony_mixer_init is then not necessary, but in case the ordering
of the calls changes, I have left it, and moved the dereference after it.

A simplified version of the semantic match that detects this problem is as
follows (http://coccinelle.lip6.fr/):

// <smpl>
@match exists@
expression x, E;
identifier fld;
@@

* x->fld
  ... when != \(x = E\|&x\)
* x == NULL
// </smpl>

Subject: net: fix sk_forward_alloc corruption

On UDP sockets, we must call skb_free_datagram() with socket locked,
or risk sk_forward_alloc corruption. This requirement is not respected
in SUNRPC.

Add a convenient helper, skb_free_datagram_locked() and use it in SUNRPC

Subject: gre: Fix dev_addr clobbering for gretap

Nathan Neulinger noticed that gretap devices get their MAC address
from the local IP address, which results in invalid MAC addresses
half of the time.

This is because gretap is still using the tunnel netdev ops rather
than the correct tap netdev ops struct.

This patch also fixes changelink to not clobber the MAC address
for the gretap case.

Subject: ipw2200: fix oops on missing firmware

For non-monitor interfaces, the syntax for alloc_ieee80211/free_80211
is wrong. Because alloc_ieee80211 only creates (wiphy_new) a wiphy, but
free_80211() does wiphy_unregister() also. This is only correct when
the later wiphy_register() is called successfully, which apparently
is not the case for your fw doesn't exist one.

Subject: b43: Fix DMA TX bounce buffer copying

b43 allocates a bouncebuffer, if the supplied TX skb is in an invalid
memory range for DMA.
However, this is broken in that it fails to copy over some metadata to the
new skb.

This patch fixes three problems:
* Failure to adjust the ieee80211_tx_info pointer to the new buffer.
  This results in a kmemcheck warning.
* Failure to copy the skb cb, which contains ieee80211_tx_info, to the new skb.
  This results in breakage of various TX-status postprocessing (Rate control).
* Failure to transfer the queue mapping.
  This results in the wrong queue being stopped on saturation and can result in queue overflow.

The patch e43419f9:

	ath9k: downgrade assert in rc.c for invalid rate

downgraded an ASSERT to a WARN_ON() but also misplaced a
semicolon at the end of the second check. What this did
was force the rate control code to always return the rate
even if we should have warned about it. Since this should
not have happened anymore anyway this fix isn't critical
as the proper rate would have been returned anyway.

To fix this, always del_timer_sync() the timer in
ieee80211_process_addba_resp() and add it again
after checking the conditions, if necessary.

Subject: libertas if_usb: Fix crash on 64-bit machines

On a 64-bit kernel, skb->tail is an offset, not a pointer. The libertas
usb driver passes it to usb_fill_bulk_urb() anyway, causing interesting
crashes. Fix that by using skb->data instead.

This highlights a problem with usb_fill_bulk_urb(). It doesn't notice
when dma_map_single() fails and return the error to its caller as it
should. In fact it _can't_ currently return the error, since it returns
void.

So this problem was showing up only at unmap time, after we'd already
suffered memory corruption by doing DMA to a bogus address.

This patch prevents the driver from calling misc_deregister twice on the same
ressouce when unloading the driver.
Unloading the driver without this patch results in a Kernel BUG like this:
Panel driver version 0.9.5 registered on parport0 (io=0x378).
BUG: unable to handle kernel paging request at 0000000000100108

Oops: 0002 [#1] PREEMPT SMP
last sysfs file: /sys/devices/platform/w83627hf.656/in8_input

This patch fixes this issue, although maybe not in the best way possible :)

Subject: Staging: rtl8187se/rtl8192e/rtl8192su: allow module unload

On rtl81* additions, they had its wireless stack made builtin instead of
separated modules. But try_module_get/module_put in stack were kept,
they are uneeded with the stack builtin and makes rtl81* modules
impossible to remove on a system with an rtl81* card. request_module
calls are also uneeded with stack builtin, so remove them too.

From 9ab1b56aa02aa4d578232a8addc785c91e7b2bac Mon Sep 17 00:00:00 2001
From: Greg Kroah-Hartman <gregkh@suse.de>
Date: Mon, 26 Oct 2009 16:35:32 -0700
Subject: Staging: remove stlc45xx driver

It's no longer needed as the p54spi driver is the same thing,
under a different name and in the correct portion of the kernel tree.

The MTU throttle-down if a RNDIS device doesn't support a particular
packet size is being incorrectly logged.  The attempted packet size is
being clobbered before it gets logged.

First patch; please inform if I'm doing this incorrectly.  Diff'd
against latest official source as per the FAQ; forward port to current
git version is straightforward.

Subject: USB: serial: sierra driver send_setup() autopm fix

This patch presents a fix for the autosuspend feature implementation in
sierra usb serial driver for function sierra_send_setup().  Because it
is possible to call sierra_send_setup() before sierra_open() or after
sierra_close() we added a get/put interface activity to assure that the
usb control can happen even when the device is autosuspended.

Subject: USB: serial: sierra driver autopm fixes

This patch presents fixes for the autosuspend feature implementation in
sierra usb serial driver in  functions sierra_open(), sierra_close() and
stop_read_write_urbs().

The patch "sierra_close() must resume the device before it notifies it
of a closure" submitted by Oliver Neukum on Wed, October 14 has been
merged as fix in sierra_close() function.

The bug fix  in sierra_open() function restores the autopm interface
state on error condition.

The bug fix in in stop_read_write_urbs() function assures that both
receive and interrupt urbs are recycled.

Subject: USB: fsl_udc_core: Fix kernel oops on module removal

fsl_udc_release() calls dma_free_coherent() with an inappropriate
device passed to it, and since the device has no dma_ops, the following
oops pops up:

a correct device.

Subject: Driver core: fix driver_register() return value

In this patch:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=16dc42e018c2868211b4928f20a957c0c216126c
the check was added for another driver to already claim the same device
on the same bus. But the returned error code was wrong: to modprobe, the
-EEXIST means that _this_ driver is already installed. It therefore
doesn't produce the needed error message when _another_ driver is trying
to register for the same device.  Returning -EBUSY fixes the problem.

Subject: Driver core: allow certain drivers prohibit bind/unbind via sysfs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Platform drivers registered via platform_driver_probe() can be bound
to devices only once, upon registration, because discard their probe()
routines to save memory. Unbinding the driver through sysfs 'unbind'
leaves the device stranded and confuses users so let's not create
bind and unbind attributes for such drivers.

Subject: Documentation: ABI: /sys/devices/system/cpu/cpu#/ topology files

Add brief descriptions for the following sysfs files:

	/sys/devices/system/cpu/cpu#/topology/core_id
	/sys/devices/system/cpu/cpu#/topology/core_siblings
	/sys/devices/system/cpu/cpu#/topology/core_siblings_list
	/sys/devices/system/cpu/cpu#/topology/physical_package_id
	/sys/devices/system/cpu/cpu#/topology/thread_siblings
	/sys/devices/system/cpu/cpu#/topology/thread_siblings_list

The descriptions in Documentation/cputopology.txt weren't very
informative, so I attempted a better description based on code
reading and hopeful guessing.

Updated Documentation/cputopology.txt with the better descriptions and
fixed some style issues.

+
+		One cpu# directory is created per logical CPU in the system,

+
+		Briefly, the files above are:
+
+		core_id: the CPU core ID of cpu#. Typically it is the
+		hardware platform's identifier (rather than the kernel's).
+		The actual value is architecture and platform dependent.
+
+		core_siblings: internal kernel map of cpu#'s hardware threads
+		within the same physical_package_id.
+
+		core_siblings_list: human-readable list of the logical CPU
+		numbers within the same physical_package_id as cpu#.
+
+		physical_package_id: physical package id of cpu#. Typically
+		corresponds to a physical socket number, but the actual value
+		is architecture and platform dependent.
+

+		threads within the same core as cpu#

Subject: NOMMU: Don't pass NULL pointers to fput() in do_mmap_pgoff()

Don't pass NULL pointers to fput() in the error handling paths of the NOMMU
do_mmap_pgoff() as it can't handle it.

The following can be used as a test program:

	int main() { static long long a[1024 * 1024 * 20] = { 0 }; return a;}

Without the patch, the code oopses in atomic_long_dec_and_test() as called by
fput() after the kernel complains that it can't allocate that big a chunk of
memory.  With the patch, the kernel just complains about the allocation size
and then the program segfaults during execve() as execve() can't complete the
allocation of all the new ELF program segments.

Subject: ALSA: pcmcia: use dynamic debug infrastructure, deprecate CS_CHECK
 (sound)

Convert PCMCIA drivers to use the dynamic debug infrastructure, instead of
requiring manual settings of PCMCIA_DEBUG.

Also, remove all usages of the CS_CHECK macro and replace them with proper
Linux style calling and return value checking. The extra error reporting may
be dropped, as the PCMCIA core already complains about any (non-driver-author)
errors.

Subject: MIPS: Don't write ones to reserved entryhi bits.

We've silently been relying on the hardware chopping off excess, reserved
ASID bits for no better reason that it saving an instruction.  Because we
already have:

#define cpu_asid(cpu, mm)       (cpu_context((cpu), (mm)) & ASID_MASK)

in <asm/mmu_context.h>.

We can use a cleanup to avoid writing non-zero bits into the reserved
entryhi bits.  This avoid triggering some debugging assertion in the
Cavium simulator.

Subject: MIPS: Add IRQF_TIMER flag for timer interrupts

Along the lines of d6c585a4342a2ff627a29f9aea77c5ed4cd76023, add IRQF_TIMER
flag for all timer interrupts  This ensures that timer interrupts won't be
disabled on suspend and not threaded for PREEMPT_RT.

This patch fixes a lockup on BCM6345 where setting the PLL soft reset bit
will also lock the other blocks including UART.  Instead of setting only
the PLL soft reset bit in the software reset register, set this bit but do
not touch the others.

Subject: MIPS: BCM63xx: Make bcm63xx_uart_register an initfunc

This patch removes the calls to bcm63xx_uart_register in board_bcm963xx.c
and make bcm63xx_uart_register an initfunc.  Allows us to remove
bcm63xx_dev_uart.h which was there to make checkpatch.pl happy.

Subject: MIPS: AR7: register watchdog device only if enabled in hw
 configuration

This patch checks if the watchdog enable bit is set in the DCL register
meaning that the hardware watchdog actually works and if so, register the
ar7_wdt platform_device.

Subject: MIPS: Fix machine check exception in kmap_coherent()

On an SMP system with cache aliases, the following sequence of events may
happen:

1) copy_user_highpage() runs on CPU0, invoking kmap_coherent() to create a
   temporary mapping in the fixmap region
2) copy_page() starts on CPU0
3) CPU1 sends CPU0 an IPI asking CPU0 to run local_r4k_flush_cache_page()
4) CPU0 takes the interrupt, interrupting copy_page()
5) local_r4k_flush_cache_page() on CPU0 calls kmap_coherent() again
6) The second invocation of kmap_coherent() on CPU0 tries to use the
   same fixmap virtual address that was being used by copy_user_highpage()
7) CPU0 throws a machine check exception for the TLB address conflict

Fixed by creating an extra set of fixmap entries for use in interrupt
handlers.  This prevents fixmap VA conflicts between copy_user_highpage()
running in user context, and local_r4k_flush_cache_page() invoked from an
SMP IPI.

Subject: MIPS: Alchemy: Fix hang with high-frequency edge interrupts

The handle_edge_irq() flowhandler disables edge int sources which occur
too fast (i.e. another edge comes in before the irq handler function
had a chance to finish).  Currently, the mask_ack() callback does not
ack the edges in hardware, leading to an endless loop in the flowhandler
where it tries to shut up the irq source.

When I rewrote the alchemy IRQ code  I wrongly assumed the mask_ack()
callback was only used by the level flowhandler, hence it omitted the
(at the time pointless) edge acks.  Turned out I was wrong; so here
is a complete mask_ack implementation for Alchemy IC, which fixes
the above mentioned problem.

Subject: 9p: fix a small bug in readdir for long directories

Here is a proposed patch for bug in readdir. Listing of dirs with
many files fails without this patch.

Subject: 9p: fix readlink

I do not know if you've looked on the patch, but unfortunately it is
incorrect. A suggested better version is in this email (the old
version didn't work in case the user provided buffer was not long
enough - it incorrectly appended null byte on a position of last char,
and thus broke the contract of the readlink method). However, I'm
still not sure this is 100% correct thing to do, I think readlink is
supposed to return buffer without last null byte in all cases, but we
do return last null byte (even the old version).. on the other hand it
is likely unspecified what is in the remaining part of the buffer, so
null character may be fine there ;):

Subject: 9p: fix readdir corner cases

The patch below also addresses a couple of other corner cases in readdir
seen with a large (e.g. 64k) msize.  I'm not sure what people think of
my co-opting of fid->aux here.  I'd be happy to rework if there's a better
way.

When the size of the user supplied buffer passed to readdir is smaller
than the data returned in one go by the 9P read request, v9fs_dir_readdir()
currently discards extra data so that, on the next call, a 9P read
request will be issued with offset < previous offset + bytes returned,
which voilates the constraint described in paragraph 3 of read(5) description.
This patch preseves the leftover data in fid->aux for use in the next call.

Subject: sched: Fix boot crash by zalloc()ing most of the cpu masks

I got a boot crash when forcing cpumasks offstack on 32 bit,
because find_new_ilb() returned 3 on my UP system (nohz.cpu_mask
wasn't zeroed).

AFAICT the others need to be zeroed too: only
nohz.ilb_grp_nohz_mask is initialized before use.

debugobjects warns about an enqueued timer being initialized. If
CONFIG_USER_SCHED=y the user management code uses delayed work to
remove the user from the hash table and tear down the sysfs objects.

free_uid is called from RCU and initializes/schedules delayed work if
the usage count of the user_struct is 0. The init/schedule happens
outside of the uidhash_lock protected region which allows a concurrent
caller of find_user() to reference the about to be destroyed
user_struct w/o preventing the work from being scheduled. If the next
free_uid call happens before the work timer expired then the active
timer is initialized and the work scheduled again.

The race was introduced in commit 5cb350ba (sched: group scheduling,
sysfs tunables) and made more prominent by commit 3959214f (sched:
delayed cleanup of user_struct)

Move the init/schedule_delayed_work inside of the uidhash_lock
protected region to prevent the race.

Subject: rcu: Fix long-grace-period race between forcing and initialization

Very long RCU read-side critical sections (50 milliseconds or
so) can cause a race between force_quiescent_state() and
rcu_start_gp() as follows on kernel builds with multi-level
rcu_node hierarchies:

1.	CPU 0 calls force_quiescent_state(), sees that there is a
	grace period in progress, and acquires ->fsqlock.

2.	CPU 1 detects the end of the grace period, and so
	cpu_quiet_msk_finish() sets rsp->completed to rsp->gpnum.
	This operation is carried out under the root rnp->lock,
	but CPU 0 has not yet acquired that lock.  Note that
	rsp->signaled is still RCU_SAVE_DYNTICK from the last
	grace period.

3.	CPU 1 calls rcu_start_gp(), but no one wants a new grace
	period, so it drops the root rnp->lock and returns.

4.	CPU 0 acquires the root rnp->lock and picks up rsp->completed
	and rsp->signaled, then drops rnp->lock.  It then enters the
	RCU_SAVE_DYNTICK leg of the switch statement.

5.	CPU 2 invokes call_rcu(), and now needs a new grace period.
	It calls rcu_start_gp(), which acquires the root rnp->lock, sets
	rsp->signaled to RCU_GP_INIT (too bad that CPU 0 is already in
	the RCU_SAVE_DYNTICK leg of the switch statement!)  and starts
	initializing the rcu_node hierarchy.  If there are multiple
	levels to the hierarchy, it will drop the root rnp->lock and
	initialize the lower levels of the hierarchy.

6.	CPU 0 notes that rsp->completed has not changed, which permits
        both CPU 2 and CPU 0 to try updating it concurrently.  If CPU 0's
	update prevails, later calls to force_quiescent_state() can
	count old quiescent states against the new grace period, which
	can in turn result in premature ending of grace periods.

	Not good.

This patch adds an RCU_GP_IDLE state for rsp->signaled that is
set initially at boot time and any time a grace period ends.
This prevents CPU 0 from getting into the workings of
force_quiescent_state() in step 4.  Additional locking and
checks prevent the concurrent update of rsp->signaled in step 6.

ARM unwind is known to compile only with EABI and not-buggy compilers.
The problem is not the unwinding information but the -fno-frame-pointer
option added as a result of !CONFIG_FRAME_POINTER.  Now we check the

Subject: ARM: ensure initial page tables are setup for SMP systems

Mapping the same memory using two different attributes (memory
type, shareability, cacheability) is unpredictable.  During boot,
we encounter a situation when we're updating the kernel's page
tables which can lead to dirty cache lines existing in the cache
which are subsequently missed.  This causes stack corruption,
and therefore a crash.

Therefore, ensure that the shared and cacheability settings
matches the configuration that will be used later; this together
with the restriction in early_cachepolicy() ensures that we won't
create a mismatch during boot.

Subject: i915: fix intel graphics suspend breakage due to resume/lid event
 confusion

In commit c1c7af60892070e4b82ad63bbfb95ae745056de0 ("drm/i915: force
mode set at lid open time") the intel graphics driver was taught to
restore the LVDS mode on lid open.

That caused problems with interaction with the suspend/resume code,
which commonly runs at the same time (suspend is often caused by the lid
close event, while lid open is commonly a resume event), which was
worked around with in commit 06891e27a9b5dba5268bb80e41a283f51335afe7
("drm/i915: fix suspend/resume breakage in lid notifier").

However, in the meantime the lid event code had also grown a user event
notifier (commit 06324194eee97a51b5f172270df49ec39192d6cc: "drm/i915:
generate a KMS uevent at lid open/close time"), and now _that_ causes
problems with suspend/resume and some versions of Xorg reacting to those
uevents by setting the mode.

So this effectively reverts that commit 06324194ee, and makes the lid
open protection logic against suspend/resume more explicit.  This fixes
at least one laptop. See

	http://bugzilla.kernel.org/show_bug.cgi?id=14484

for more details.

Subject: mm: remove incorrect swap_count() from try_to_unuse()

In try_to_unuse(), swcount is a local copy of *swap_map, including the
SWAP_HAS_CACHE bit; but a wrong comparison against swap_count(*swap_map),
which masks off the SWAP_HAS_CACHE bit, succeeded where it should fail.

That had the effect of resetting the mm from which to start searching
for the next swap page, to an irrelevant mm instead of to an mm in which
this swap page had been found: which may increase search time by ~20%.
But we're used to swapoff being slow, so never noticed the slowdown.

Remove that one spurious use of swap_count(): Bo Liu thought it merely
redundant, Hugh rewrote the description since it was measurably wrong.

Subject: Revert "ext4: Remove journal_checksum mount option and enable it by
 default"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This reverts commit d0646f7b636d067d715fab52a2ba9c6f0f46b0d7, as
requested by Eric Sandeen.

It can basically cause an ext4 filesystem to miss recovery (and thus get
mounted with errors) if the journal checksum does not match.

Quoth Eric:

   "My hand-wavy hunch about what is happening is that we're finding a
    bad checksum on the last partially-written transaction, which is
    not surprising, but if we have a wrapped log and we're doing the
    initial scan for head/tail, and we abort scanning on that bad
    checksum, then we are essentially running an unrecovered filesystem.

    But that's hand-wavy and I need to go look at the code.

    We lived without journal checksums on by default until now, and at
    this point they're doing more harm than good, so we should revert
    the default-changing commit until we can fix it and do some good
    power-fail testing with the fixes in place."

See

	http://bugzilla.kernel.org/show_bug.cgi?id=14354

for all the gory details.

Subject: cfg80211: fix NULL ptr deref

commit 211a4d12abf86fe0df4cd68fc6327cbb58f56f81
  Author: Johannes Berg <johannes@sipsolutions.net>
  Date:   Tue Oct 20 15:08:53 2009 +0900

      cfg80211: sme: deauthenticate on assoc failure

introduced a potential NULL pointer dereference that
some people have been hitting for some reason -- the
params.bssid pointer is not guaranteed to be non-NULL
for what seems to be a race between various ways of
reaching the same thing.

While I'm trying to analyse the problem more let's
first fix the crash. I think the real fix may be to
avoid doing _anything_ if it ended up being NULL, but
right now I'm not sure yet.

I think
http://bugzilla.kernel.org/show_bug.cgi?id=14342
might also be this issue.

Subject: mac80211: check interface is down before type change

For some strange reason the netif_running() check
ended up after the actual type change instead of
before, potentially causing all kinds of problems
if the interface is up while changing the type;
one of the problems manifests itself as a warning:

Subject: i2c: imx: check busy bit when START/STOP

The controller can't do anything else before it actually generates START/STOP.
So we check busy bit to make sure START/STOP is successfully finished.

If we don't check busy bit, START/STOP may fail on some fast CPUs.

Subject: i2c-mpc: Do not generate STOP after read.

The driver always ends a read with a STOP condition which
breaks subsequent I2C reads/writes in the same transaction as
these expect to do a repeated START(ReSTART).

This will also help I2C multimaster as the bus will not be released
after the first read, but when the whole transaction ends.

Subject: ext4: discard preallocation when restarting a transaction during
 truncate

When restart a transaction during a truncate operation, we drop and
reacquire i_data_sem.  After reacquiring i_data_sem, we need to
discard any inode-based preallocation that might have been grabbed
while we released i_data_sem (for example, if pdflush is allocating
blocks and racing against the truncate).

Subject: [ARM] pxa/zaurus: fix NAND flash OOB layout for Borzoi

Borzoi, Terrier and Akita use the same NAND Flash OOB layout, which
seems to be different from Spitz for some reason. Here is a fix.

When the code was ported to the platform data, the map was applied just
for Akita.

After this patch, Flash works again on Borzoi. Terrier still has a
problem with partition table different from Borzoi (unfixable without
reading of the system configuration in flash) and JFFS2 partitions can
be mounted (with some "Empty flash at ... ends at ..." in the syslog).

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Bruno Prémont and Dunphy, Bill noticed me that NILFS will certainly
hang on ARM-based targets.

I found this was caused by an underflow of dirty pages counter.  A
b-tree cache routine was marking page dirty without adjusting page
account information.

This fixes the dirty page accounting leak and resolves the hang on
arm-based targets.

Subject: nilfs2: fix irregular checkpoint creation due to data flush

When nilfs flushes out dirty data to reduce memory pressure, creation
of checkpoints is wrongly postponed.  This bug causes irregular
checkpoint creation especially in small footprint systems.

To correct this issue, a timer for the checkpoint creation has to be
continued if a log writer does not create a checkpoint.

This will do the correction.

magnitude increase in select_task_rq_fair() overhead while
running heavy wakeup benchmarks (tbench and vmark).

Since SD_BALANCE_WAKE is off at node level, turn SD_PREFER_LOCAL
off as well pending further investigation.

Subject: sched: Fix kthread_bind() by moving the body of kthread_bind() to
 sched.c

Eric Paris reported that commit
f685ceacab07d3f6c236f04803e2f2f0dbcc5afb causes boot time
PREEMPT_DEBUG complaints.

 [    4.590699] BUG: using smp_processor_id() in preemptible [00000000] code: rmmod/1314
 [    4.593043] caller is task_hot+0x86/0xd0

Since kthread_bind() messes with scheduler internals, move the
body to sched.c, and lock the runqueue.

Subject: PM / yenta: Split resume into early and late parts (rev. 4)

Commit 0c570cdeb8fdfcb354a3e9cd81bfc6a09c19de0c
(PM / yenta: Fix cardbus suspend/resume regression) caused resume to
fail on systems with two CardBus bridges.  While the exact nature
of the failure is not known at the moment, it can be worked around by
splitting the yenta resume into an early part, executed during the
early phase of resume, that will only resume the socket and power it
up if there was a card in it during suspend, and a late part,
executed during "regular" resume, that will carry out all of the
remaining yenta resume operations.

Fixes http://bugzilla.kernel.org/show_bug.cgi?id=14334, which is a
listed regression from 2.6.31.

Subject: PM / Hibernate: Fix blkdev refleaks

While cruising through the swsusp code I found few blkdev reference
leaks of resume_bdev.

swsusp_read: remove blkdev_put altogether. Some fail paths do
             not do that.
swsusp_check: make sure we always put a reference on fail paths
software_resume: all fail paths between swsusp_check and swsusp_read
                 omit swsusp_close. Add it in those cases. And since
                 swsusp_read doesn't drop the reference anymore, do
                 it here unconditionally.

[rjw: Fixed a small coding style issue.]

Subject: PM / Hibernate: Fix error handling in save_image()

There are too many retval variables in save_image(). Thus error return
value from snapshot_read_next() may be ignored and only part of the
snapshot (successfully) written.

Remove 'error' variable, invert the condition in the do-while loop
and convert the loop to use only 'ret' variable.

Switch the rest of the function to consider only 'ret'.

Also make sure we end printed line by \n if an error occurs.

 when associated"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

rt2860sta is fine with the patch as is, but iwl3945 isn't
(eeepc_rfkill_set() needs to call eeepc_rfkill_hotplug(true) – which means
that we're back to causing the rt2860sta panic

Switching the camera takes 500ms, checking if it's on is almost free...
The BIOS remembers the setting through reboots, so there's good chance the
camera is already enabled.

Subject: Correct nr_processes() when CPUs have been unplugged

nr_processes() returns the sum of the per cpu counter process_counts for
all online CPUs. This counter is incremented for the current CPU on
fork() and decremented for the current CPU on exit(). Since a process
does not necessarily fork and exit on the same CPU the process_count for
an individual CPU can be either positive or negative and effectively has
no meaning in isolation.

Therefore calculating the sum of process_counts over only the online
CPUs omits the processes which were started or stopped on any CPU which
has since been unplugged. Only the sum of process_counts across all
possible CPUs has meaning.

The only caller of nr_processes() is proc_root_getattr() which
calculates the number of links to /proc as
        stat->nlink = proc_root.nlink + nr_processes();

You don't have to be all that unlucky for the nr_processes() to return a
negative value leading to a negative number of links (or rather, an
apparently enormous number of links). If this happens then you can get
failures where things like "ls /proc" start to fail because they got an
-EOVERFLOW from some stat() call.

Example with some debugging inserted to show what goes on:
        # ps haux|wc -l
        nr_processes: CPU0:     90
        nr_processes: CPU1:     1030
        nr_processes: CPU2:     -900
        nr_processes: CPU3:     -136
        nr_processes: TOTAL:    84

        nr_processes: CPU2:     -901
        nr_processes: CPU3:     -137

I'm not 100% convinced that the per_cpu regions remain valid for offline
CPUs, although my testing suggests that they do. If not then I think the
correct solution would be to aggregate the process_count for a given CPU
into a global base value in cpu_down().

This bug appears to pre-date the transition to git and it looks like it
may even have been present in linux-2.6.0-test7-bk3 since it looks like
the code Rusty patched in http://lwn.net/Articles/64773/ was already
wrong.

We never want to rely on the hvc workqueue to emit output, because the

improve oops/crash/console message for better debugging.

Instead, we force-poll until all output is emitted.

Subject: xen: mask extended topology info in cpuid

A Xen guest never needs to know about extended topology, and knowing
would just confuse it.

This patch just zeros ebx in leaf 0xb which indicates no topology info,
preventing a crash under Xen on cpus which support this leaf.

Commit 592b09a42fc3ae6737a0f3ecf4fee42ecd0296f8 was different from
the tested path, in that it moved the bdi super_block prune from
unregister to destroy context. This doesn't fully fix the sync hang
bug on unexpected device removal, as need to prune the bdi cache
pointer before killing flusher thread.

Subject: cfq-iosched: limit coop preemption

CFQ has an optimization for cooperated applications. if several
io-context have close requests, they will get boost. But the
optimization get abused. Considering thread a, b, which work on one
file. a reads sectors s, s+2, s+4, ...; b reads sectors s+1, s+3, s
+5, ... Both a and b are sequential read, so they can open idle window.
a reads a sector s and goes to idle window and wakeup b. b reads sector
s+1, since in current implementation, cfq_should_preempt() thinks a and
b are cooperators, b will preempt a. b then reads sector s+1 and goes to
idle window and wakeup a. for the same reason, a will preempt b and
reads s+2. a and b will continue the circle. The circle will be very
long, and a and b will occupy whole disk queue. Other applications will
nearly have no chance to run.

Fix this limiting coop preempt until a queue is scheduled normally
again.

Subject: ext4: fix ext4_ext_direct_IO()'s return value after converting uninit
 extents

After a direct I/O request covering an uninitalized extent (i.e.,
created using the fallocate system call) or a hole in a file, ext4
will convert the uninitialized extent so it is marked as initialized
by calling ext4_convert_unwritten_extents().  This function returns
zero on success.

This return value was getting returned by ext4_direct_IO(); however
the file system's direct_IO function is supposed to return the number
of bytes read or written on a success.  By returning zero, it confused
the direct I/O code into falling back to buffered I/O unnecessarily.

 isn't any

At the end of direct I/O operation, ext4_ext_direct_IO() always called
ext4_convert_unwritten_extents(), regardless of whether there were any
unwritten extents involved in the I/O or not.

This commit adds a state flag so that ext4_ext_direct_IO() only calls
ext4_convert_unwritten_extents() when necessary.

Subject: ext4: code clean up for dio fallocate handling

The ext4_debug() call in ext4_end_io_dio() should be moved after the
check to make sure that io_end is non-NULL.

The comment above ext4_get_block_dio_write() ("Maximum number of
blocks...") is a duplicate; the original and correct comment is above
the #define DIO_MAX_BLOCKS up above.

Based on review comments from Curt Wohlgemuth.

Subject: m32r: add NOTES to vmlinux.lds.S to remove .note.gnu.build-id section

Building with --build-id option, .note.gnu.build-id section is added
to vmlinux.bin.  But some old buggy binutils creates a huge vmlinux.bin,
and a bootloader fails to boot its zImage as well.

This patch adds a NOTES macro to a linker script vmlinux.ld.S to put
.note.gnu.build-id section into .note section.
Then, the .note section will be removed, because "-R .note" option is
specified in OBJCOPYFLAGS to make a vmlinux.bin binary.

Subject: drm/radeon/kms: fix coherency issues on AGP cards.

When we are evicting from VRAM->RAM we allocate the ttm object,
but we don't set the caching policy on it before blitting into it.
This means on AGP we end up blitting into cached pages, and
the CPU later flushes out on top of them. This was mostly seen as
font corruption.

The other question is why we don't evict VRAM->GTT in a lot of cases,
this would save us some cache transitions since a lot of objects
that are evicted from VRAM will probably end up being pulled back in
a few operations later, and evicting them to system memory involves
2 unnecessary cache transitions.

Subject: drm/radeon/kms: Don't RMW CP_RB_CNTL

Immediate readback seems faulty on some chips.  I
suspect it takes a while to get through the fifo
to the actual register backbone.  There's no need
to read it back, so, just write the driver's copy
of the register's value directly.

Should fix bug 24535 and possibly 24218

Subject: drm/radeon/kms: disable D1VGA and D2VGA if enabled

Once kms is enabled we don't need these, and it causes a problem
with the Lenovo W500 ACPI brightness implementation, it hangs
in a loop inside an SMI.

Subject: drm/radeon/kms: stop putting VRAM at 0 in MC space on r600s.

The Lenovo W500 laptop hangs inside an SMI on brightness changes,
I thought it just needed the VGA disable but it turned out to require
slightly more work, setting the MC locations up just like the IGP
chip requirements seems to make it all happy again and I can boot
and play with brightness.

We should probably just do this for all chips and give up the VRAM
at 0x0 idea, it never seems to buy us anything but pain.

This patch enables GPIO to control mute LED indicator on the HP systems

HP B-series systems.

It also restores configuration of the pin intended as the second Headphone
on HP B-series systems but configured as something else in the BIOS to

Subject: fuse: prevent fuse_put_request on invalid pointer

fuse_direct_io() has a loop where requests are allocated in each
iteration. if allocation fails, the loop is broken out and follows
into an unconditional fuse_put_request() on that invalid pointer.

Subject: x86, fs: Fix x86 procfs stack information for threads on 64-bit

This patch fixes two issues in the procfs stack information on
x86-64 linux.

The 32 bit loader compat_do_execve did not store stack
start. (this was figured out by Alexey Dobriyan).

The stack information on a x64_64 kernel always shows 0 kbyte
stack usage, because of a missing implementation of the KSTK_ESP
macro which always returned -1.

The new implementation now returns the right value.

allow user space to fill up to 255 on setup (mcg_cap & 0xff), corrupting
kernel memory. Catch these overflows.

Subject: KVM: get_tss_base_addr() should return a gpa_t

If TSS we are switching to resides in high memory task switch will fail
since address will be truncated. Windows2k3 does this sometimes when
running with more then 4G

While refreshing my sysfs patches I noticed a leak in the secdata
implementation.  We don't free the secdata when we free the
sysfs dirent.

This is a bug in 2.6.32-rc5 that we really should close.

Subject: rtl8187: Fix kernel oops when device is removed when LEDS enabled

As reported by Rick Farina (sidhayn@gmail.com), removing the RTL8187
USB stick, or unloading the driver rtl8187 using rmmod will cause a
kernel oops.  There are at least two forms of the failure, (1) BUG:
Scheduling while atomic, and (2) a fatal kernel page fault. This
problem is reported in Bugzilla #14539.

This problem does not occur for kernel 2.6.31, but does for 2.6.32-rc2,
thus it is technically a regression; however, bisection did not locate
any faulty patch. The fix was found by comparing the faulty code in
rtl8187 with p54usb.  My interpretation is that the handling of work
queues in mac80211 changed enough to the LEDs to be unregistered
before tasks on the work queues are cancelled. Previously, these
actions could be done in either order.

(Herton Ronaldo Krzesinski <herton@mandriva.com.br> reports that the
code is the same in 2.6.31, so this may be a candidate for 2.6.31.x.

Patch f598282f5145036312d90875d0ed5c14b49fd8a7 exposed a problem in
powerpc MSI-X functionality, making network interfaces such as ixgbe
and cxgb3 stop to work when MSI-X is enabled. RX interrupts were not
being generated.

The problem was caused because MSI irq was not being effectively
unmasked after device initialization.

Commit

	3d1285b (move virtnet_remove to .devexit.text)

introduced the first reference to __devexit in struct virtio_driver
virtio_net which upset modpost ("Section mismatch in reference from the
variable virtio_net to the function .devexit.text:virtnet_remove()").

Fix this by renaming virtio_net to virtio_net_driver.

Subject: RealView: Add sparsemem support for the RealView PBX platform

The RealView PBX board has two 512MB blocks of memory - one at
0x70000000 (with 256MB mirror at 0) and another at 0x20000000. Only the
block at 0x70000000 (or the mirror at 0) may be used for DMA (e.g.
framebuffer). This patch adds the sparsemem definitions to allow the use
of all the memory split as follows:

  256MB @ 0x00000000 (ZONE_DMA)
  512MB @ 0x20000000 (ZONE_NORMAL)
  256MB @ 0x80000000 (ZONE_NORMAL)

Subject: powerpc/85xx: sbc8548 - fixup of PCI-e related DTS fields

The PCI-e addressing was originally patterned of the MPC8548CDS
which has PCI1, PCI2, and PCI-e.  Since this board only has
PCI1 and PCI-e, it makes more sense to be similar to the MPC8568MDS
board.  This does that by cutting the PCI/PCI-e I/O sizes from
16MB to 8MB and pulling the PCI-e I/O range back to 0xe280_0000
(the hole where PCI2 I/O would have been).

This also fixes a typo where an extra zero made an 8MB range a 128MB
range, removes the hole left by PCI2 from the aliases, and sets the
clocks to match the oscillators that are actually on the board.

With accompanying u-boot updates, PCI-e has been validated with
both a sky2 card (1148:9e00) and an e1000 card (8086:108b).

This patch fixes USB GPIOs numbers for MPC8569E-MDS boards, plus
according to the latest HW Getting Started Guide (rev 3.3, pilot
boards), USB "POWER" GPIO polarity has changed, it is no longer
inverted.

This patch makes USB Host somewhat work on pilot boards, though
there are still some problems with determining devices speed and
long bulk transfers.

Subject: acpi-power-meter: Don't leak ACPI error codes to userspace

If the ACPI methods return an error code, we must return -EINVAL to userspace
to flag the error.  Right now we pass the (positive) number right through,
which causes echo to keep writing bogus values.

From d39b7dd1dcbf394a1cb897457c862dafe9a20ac5 Mon Sep 17 00:00:00 2001
From: Linus Torvalds <torvalds@linux-foundation.org>
Date: Thu, 5 Nov 2009 10:48:30 -0800
Subject: sgi-gru: decrapfiy options_write() function

Not a single line of actual code in the function was really
fundamentally correct.

Problems ranged from lack of proper range checking, to removing the last
character written (which admittedly is usually '\n'), to not accepting
hex numbers even though the 'show' routine would show the data in that
format.

This tries to do better.

Subject: x86: Make sure get_user_desc() doesn't sign extend.

The current implementation of get_user_desc() sign extends the return
value because of integer promotion rules.  For the most part, this
doesn't matter, because the top bit of base2 is usually 0.  If, however,
that bit is 1, then the entire value will be 0xffff...  which is
probably not what the caller intended.

This patch casts the entire thing to unsigned before returning, which
generates almost the same assembly as the current code but replaces the
final "cltq" (sign extend) with a "mov %eax %eax" (zero-extend).  This
fixes booting certain guests under KVM.

Subject: ACPI: add __cpuinit to acpi_processor_add()

Annote acpi_processor_add with cpuinit since it calls a cpuinit function
acpi_processor_power_init and fixes a section mismatch warning.

 We were warned by the following warning:

 LD      drivers/acpi/processor.o
WARNING: drivers/acpi/processor.o(.text+0x1829): Section mismatch in
reference from the function acpi_processor_add() to the function
.cpuinit.text:acpi_processor_power_init()
The function acpi_processor_add() references
the function __cpuinit acpi_processor_power_init().
This is often because acpi_processor_add lacks a __cpuinit
annotation or the annotation of acpi_processor_power_init is wrong.

Subject: ACPICA: avoid "Info: mapping multiple BARs. Your kernel is fine."

Ensure that memory mappings created for operation regions
do not cross page boundaries.  Crossing a page boundary
while mapping regions can cause warnings if the pages have different attributes.

Such regions are probably BIOS bugs, and this is the workaround.

Subject: drm/radeon/kms/atom/dce3: call transmitter init on mode set

Generally this is done at post, but might not always be done
with softboot or for connectors on docking stations.

Could probably be done once when the driver loads/resumes
rather than on each mode set.

Subject: md: don't clear endpoint for resync when resync is interrupted.

If a 'sync_max' has been set (via sysfs), it is wrong to clear it
until a resync (or reshape or recovery ...) actually reached that
point.
So if a resync is interrupted (e.g. by device failure),
leave 'resync_max' unchanged.

This is particularly important for 'reshape' operations that do not
change the size of the array.  For such operations mdadm needs to
monitor the reshape taking rolling backups of the section being
reshaped.  If resync_max gets cleared, the reshape can get ahead of
mdadm and then the backups that mdadm creates are useless.

This is suitable for 2.6.31.y stable kernels.

Subject: md/raid5: make sure curr_sync_completes is uptodate when reshape
 starts

This value is visible through sysfs and is used by mdadm
when it manages a reshape (backing up data that is about to be
rearranged).  So it is important that it is always correct.
Current it does not get updated properly when a reshape
starts which can cause problems when assembling an array
that is in the middle of being reshaped.

This is suitable for 2.6.31.y stable kernels.

Subject: [ARM] kirkwood: fix section mismatch

kirkwood_timer_init() and kirkwood_pcie_setup() lack of __init which
causes following warnings:

WARNING: vmlinux.o(.text+0x9568): Section mismatch in reference from
the function kirkwood_timer_init() to the function
.init.text:kirkwood_find_tclk()
The function kirkwood_timer_init() references
the function __init kirkwood_find_tclk().
This is often because kirkwood_timer_init lacks a __init
annotation or the annotation of kirkwood_find_tclk is wrong.

WARNING: vmlinux.o(.text+0x979c): Section mismatch in reference from
the function kirkwood_pcie_setup() to the function
.init.text:orion_pcie_setup()
The function kirkwood_pcie_setup() references
the function __init orion_pcie_setup().
This is often because kirkwood_pcie_setup lacks a __init
annotation or the annotation of orion_pcie_setup is wrong.

The dwarf unwinder presently attempts to provide a sane PC value if none

fixes up the test and prevents the unwinder from blowing up.

Subject: netfilter: nf_nat: fix NAT issue in 2.6.30.4+

Vitezslav Samel discovered that since 2.6.30.4+ active FTP can not work
over NAT. The "cause" of the problem was a fix of unacknowledged data
detection with NAT (commit a3a9f79e361e864f0e9d75ebe2a0cb43d17c4272).
However, actually, that fix uncovered a long standing bug in TCP conntrack:
when NAT was enabled, we simply updated the max of the right edge of
the segments we have seen (td_end), by the offset NAT produced with
changing IP/port in the data. However, we did not update the other parameter
(td_maxend) which is affected by the NAT offset. Thus that could drift
away from the correct value and thus resulted breaking active FTP.

The patch below fixes the issue by *not* updating the conntrack parameters
from NAT, but instead taking into account the NAT offsets in conntrack in a
consistent way. (Updating from NAT would be more harder and expensive because
it'd need to re-calculate parameters we already calculated in conntrack.)

Subject: ext4: Fix return value of ext4_split_unwritten_extents() to fix
 direct I/O

To prepare for a direct I/O write, we need to split the unwritten
extents before submitting the I/O.  When no extents needed to be
split, ext4_split_unwritten_extents() was incorrectly returning 0
instead of the size of uninitialized extents. This bug caused the
wrong return value sent back to VFS code when it gets called from
async IO path, leading to an unnecessary fall back to buffered IO.

This bug also hid the fact that the check to see whether or not a
split would be necessary was incorrect; we can only skip splitting the
extent if the write completely covers the uninitialized extent.

Subject: Revert "ide: try to use PIO Mode 0 during probe if possible"

This reverts commit 6029336426a2b43e4bc6f4a84be8789a047d139e.

Ok, we really do need to revert this, even with Bart's sis5513.c
fix in there.

The problem is that several driver's ->set_pio_mode() method
depends upon the drive->media type being set properly.  Most
of them use this to enable prefetching, which can only be done
for disk media.

But the commit being reverted here calls ->set_pio_mode() before
it's setup.  Actually it considers everything disk because that
is the default media type set by ide_port_init_devices_data().

The set of drivers that depend upon the media type in their
->set_pio_method() are:

drivers/ide/alim15x3.c
drivers/ide/it8172.c
drivers/ide/it8213.c
drivers/ide/pdc202xx_old.c
drivers/ide/piix.c
drivers/ide/qd65xx.c
drivers/ide/sis5513.c
drivers/ide/slc90e66.c

And it is possible that we could fix this by guarding the prefetching
and other media dependent setting changes with a test on
IDE_PFLAG_PROBING in hwif->port_flags, that's simply too risky for
2.6.32-rcX and -stable.

Subject: ASoC: OMAP: Don't try to set unsupported OMAP_DMA_DATA_BURST_16 on
 OMAP1

After DMA burst mode has been introduced in sound/soc/omap/omap-pcm.c,
omap_pcm_prepare() unconditionally calls:

        omap_set_dma_src_burst_mode(prtd->dma_ch, OMAP_DMA_DATA_BURST_16);
        omap_set_dma_dest_burst_mode(prtd->dma_ch, OMAP_DMA_DATA_BURST_16);

Current implementation of those two functions found in
arch/arm/plat-ompa/dma.c doesn't support OMAP_DMA_DATA_BURST_16 on OMAP1 at
all, so they both end with BUG() on that machine. That results in
ASoC being completely unusable, at least on my OMAP5910 based Amstrad Delta.

The patch corrects the problem by not calling those two functions when run on
OMAP1 class based machines.

Created against linux-2.6.32-rc5.
Tested on Amstrad Delta.

Subject: [SCSI] ipr: add workaround for MSI interrupts on P7

This patch adds some additional logic to the interrupt service routine to fix
a potential problem where an MSI interrupt does not get cleared the first time.

Subject: [SCSI] pmcraid: Fix ppc64 driver build for using cpu_to_le32 on U8
 data type

Fix a reported ppc64 driver build issue. Removed cpu_to_le32 conversion
usage for flags in struct pmcraid_ioadl_desc. This was breaking the driver build in ppc64.

drivers/scsi/pmcraid.c: In function 'pmcraid_request_sense':

Subject: [SCSI] Fix incorrect reporting of host protection capabilities

The advent of DIF Type 2 devices exposed some missing break statements
in the protection mask switch constructs.  However, rewriting the code
to use an index into a small static array seemed like a more elegant
solution.

Subject: BUG: oops when "rmmod ipw2200"

This happened on wireless-testing v2.6.32-rc6-41575-g5e68bfb. I
modprobed ipw2200, put it into monitor mode, used tshark a while to
monitor, then I stopped tshark, "ifconfig eth2 down" and finally
"rmmod ipw2200", and voila:

Subject: PCI ASPM: fix oops on root port removal

Fix the following BUG_ON() problem reported by Alex Chiang.

This problem happened when removing PCIe root port using PCI logical
hotplug operation.

The immediate cause of this problem is that the pointer to invalid
data structure is passed to pcie_update_aspm_capable() by
pcie_aspm_exit_link_state(). When pcie_aspm_exit_link_state() received
a pointer to root port link, it unconfigures the root port link and
frees its data structure at first. At this point, there are not links
to configure under the root port and the data structure for root port
link is already freed. So pcie_aspm_exit_link_state() must not call
pcie_update_aspm_capable() and pcie_config_aspm_path().

This patch fixes the problem by changing pcie_aspm_exit_link_state()
not to call pcie_update_aspm_capable() and pcie_config_aspm_path() if
the specified link is root port link.

Subject: cifs: clean up handling when server doesn't consistently support
 inode numbers

It's possible that a server will return a valid FileID when we query the
FILE_INTERNAL_INFO for the root inode, but then zeroed out inode numbers
when we do a FindFile with an infolevel of
SMB_FIND_FILE_ID_FULL_DIR_INFO.

In this situation turn off querying for server inode numbers, generate a
warning for the user and just generate an inode number using iunique.
Once we generate any inode number with iunique we can no longer use any
server inode numbers or we risk collisions, so ensure that we don't do
that in cifs_get_inode_info either.

Subject: cifs: don't use CIFSGetSrvInodeNumber in is_path_accessible

Because it's lighter weight, CIFS tries to use CIFSGetSrvInodeNumber to
verify the accessibility of the root inode and then falls back to doing a
full QPathInfo if that fails with -EOPNOTSUPP. I have at least a report
of a server that returns NT_STATUS_INTERNAL_ERROR rather than something
that translates to EOPNOTSUPP.

Rather than trying to be clever with that call, just have
is_path_accessible do a normal QPathInfo. That call is widely
supported and it shouldn't increase the overhead significantly.

If be2 goes into suspend after a user changes the flow control settings,
we are not programming them back after resume. This patch takes care of it.
We now get the flow control settings before going to suspend mode and
then apply them during resume.

Subject: be2net: Bug fix to send config commands to hardware after
 netdev_register

Sending config commands to be2 hardware before netdev_register is
completed, is sometimes causing the async link notification to arrive
even before the driver is ready to handle it. The commands for vlan
config and flow control settings can infact wait till be_open.
This patch takes care of that.

Subject: ixgbe: Fix checking TFCS register for TXOFF status when DCB is
 enabled

When DCB is enabled, the ixgbe_check_tx_hang() should check the corresponding
TC's TXOFF in TFCS based on the TC that the tx ring belongs to. Adds a
function to map from the tx_ring hw reg_idx to the correspodning TC and read
TFCS accordingly.

Subject: ipip: Fix handling of DF packets when pmtudisc is OFF

RFC 2003 requires the outer header to have DF set if DF is set
on the inner header, even when PMTU discovery is off for the
tunnel.  Our implementation does exactly that.

For this to work properly the IPIP gateway also needs to engate
in PMTU when the inner DF bit is set.  As otherwise the original
host would not be able to carry out its PMTU successfully since
part of the path is only visible to the gateway.

Unfortunately when the tunnel PMTU discovery setting is off, we
do not collect the necessary soft state, resulting in blackholes
when the original host tries to perform PMTU discovery.

This problem is not reproducible on the IPIP gateway itself as
the inner packet usually has skb->local_df set.  This is not
correctly cleared (an unrelated bug) when the packet passes
through the tunnel, which allows fragmentation to occur.  For
hosts behind the IPIP gateway it is readily visible with a simple
ping.

This patch fixes the problem by performing PMTU discovery for
all packets with the inner DF bit set, regardless of the PMTU
discovery setting on the tunnel itself.

Subject: hisax: remove bad udelay call to fix build error on ARM

The hisax ISDN driver fails to build on ARM with CONFIG_HISAX_ELSA:

| drivers/built-in.o: In function `modem_set_dial':
| drivers/isdn/hisax/elsa_ser.c:535: undefined reference to `__bad_udelay'
| drivers/isdn/hisax/elsa_ser.c:544: undefined reference to `__bad_udelay'
| drivers/built-in.o: In function `modem_set_init':
| drivers/isdn/hisax/elsa_ser.c:486: undefined reference to `__bad_udelay'
| [...]

According to the comment in arch/arm/include/asm/delay.h, __bad_udelay
is specifically designed on ARM to produce a build failure when udelay
is called with a value > 2000.

Subject: ALSA: usb-audio: fix combine_word problem

Fix combine_word problem where first octet is not
read properly. The only affected place seems to be the
INPUT_TERMINAL type. Before now, sound controls can be created
with the output terminal's name which is a fallback mechanism
used only for unknown input terminal types. For example,
Line can wrongly appear as Speaker. After the change it
should appear as Line.

	The side effect of this change can be that users
can expect the wrong control name in their scripts or
programs while now we return the correct one.

	Probably, these defines should use get_unaligned_le16 and
friends.

Subject: ALSA: hda - Don't initialize CORB/RIRB for single_cmd mode

So far, CORB/RIRB still remains even if the driver is switched to the
single_cmd mode.  The specification says that this should be disabled,
but I hoped this isn't the case; indeed most devices worked together with
CORB/RIRB.

However, Poulsbo (US15W) seems problematic with this setup, and it
requires to disable CORB/RIRB when single_cmd is used.

Now this patch disables CORB/RIRB initialization when the single_cmd
mode is used.  Also the unsolicited event is disabled because it can't
work without RIRB.

Subject: V4L/DVB (13079): dib0700: fixed xc2028 firmware loading kernel oops

Fixing kernel oops when driver attemps to load xc2028 firmware.

Note by djh: the patch contribute by Martin is a port of a fix I made during
the PCTV 340e development.  It's a temporary workaround that fixes a regression
(an OOPS condition) and the real fix should be in the code that manages the
i2c master on the dib7000p.  But this fix does address the immmediate
regression and should be merged upstream until we do a cleaner fix.

Subject: V4L/DVB (13107): tda18271: fix overflow in FM radio frequency
 calculation

Multiplication by 62500 causes an overflow in the 32 bit freq variable,
which is later divided by 1000 when using FM radio.

This patch prevents the overflow by scaling the frequency value correctly
upfront.  Thanks to Henk Vergonet for spotting the problem and providing
a preliminary patch, which this changeset was based upon.

Subject: V4L/DVB (13109): tda18271: fix signedness issue in
 tda18271_rf_tracking_filters_init

While having tda18271 module set with debug=17 (cal & info prints) and
cal=0 (delay calibration process until first use) - I discovered that
during the calibration process, if the frequency test for 69750000
returned a bcal of 0 (see tda18721-fe.c in tda18271_powerscan func) that
the tuner wouldn't be able to pickup any of the frequencies in the range
(all the other frequencies bands returned bcal=1).  I spent some time
going over the code and the NXP's tda18271 spec (ver.4 of it i think) and
adding a lot of debug prints and walking/stepping through the calibration
process.  I found that when the powerscan fails to find a frequency, the
rf calibration is not run and the default value is supposed to be used in
its place (pulled from the RF_CAL_map table) - but something was getting
goofed up there.

Now, my c coding skills are very rusty, but i think root of the problem is
a signedness issue with the math operation for calculating the rf_a1 and
rf_a2 values in tda18271_rf_tracking_filters_init func, which results in
values like 20648 for rf_a1 (when it should probably have a value like 0,
or so slightly negative that it should be zero - this bad value for rf_a1
would in turn makes the approx calc within
tda18271c2_rf_tracking_filters_correction go out of whack).  The simplest
solution i found was to explicitly convert the signedness of the
denominator to avoid the implicit conversion.  The values placed into the
u32 rf_freq array should never exceed about 900mhz, so i think the s32 max
value shouldn't be an issue in this case.

I've tested it out a little, and even when i get a bcal=0 with the
modified code, the default calibration value gets used, rf_a1 is zero, and
the tuner seems to lock on the stream and mythtv seems to play it fine.

Subject: V4L/DVB (13169): bttv: Fix potential out-of-order field processing

There is a subtle interaction in the bttv driver which can result in
fields being repeatedly processed out of order.  This is a problem
specifically when running in V4L2_FIELD_ALTERNATE mode (probably the
most common case).

1. The determination of which fields are associated with which buffers
happens in videobuf, before the bttv driver gets a chance to queue the
corresponding DMA.  Thus by the point when the DMA is queued for a
given buffer, the algorithm has to do the queuing based on the
buffer's already assigned field type - not based on which field is
"next" in the video stream.

2. The driver normally tries to queue both the top and bottom fields
at the same time (see bttv_irq_next_video()).  It tries to sort out
top vs bottom by looking at the field type for the next 2 available
buffers and assigning them appropriately.

3. However the bttv driver *always* actually processes the top field
first.  There's even an interrupt set aside for specifically
recognizing when the top field has been processed so that it can be
marked done even while the bottom field is still being DMAed.

Given all of the above, if one gets into a situation where
bttv_irq_next_video() gets entered when the first available buffer has
been pre-associated as a bottom field, then the function is going to
process the buffers out of order.  That first available buffer will be
put into the bottom field slot and the buffer after that will be put
into the top field slot.  Problem is, since the top field is always
processed first by the driver, then that second buffer (the one after
the first available buffer) will be the first one to be finished.
Because of the strict fifo handling of all video buffers, then that
top field won't be seen by the app until after the bottom field is
also processed.  Worse still, the app will get back the
chronologically later bottom field first, *before* the top field is
received.  The buffer's timestamps will even be backwards.

While not fatal to most TV apps, this behavior can subtlely degrade
userspace deinterlacing (probably will cause jitter).  That's probably
why it has gone unnoticed.  But it will also cause serious problems if
the app in question discards all but the latest received buffer (a
latency minimizing tactic) - causing one field to only ever be
displayed since the other is now always late.  Unfortunately once you
get into this state, you're stuck this way - because having consumed
two buffers, now the next time around the "first" available buffer
will again be a bottom field and the same thing happens.

How can we get into this state?  In a perfect world, where there's
always a few free buffers queued to the driver, it should be
impossible.  However if something disrupts streaming, e.g. if the
userspace app can't queue free buffers fast enough for a moment due
perhaps to a CPU scheduling glitch, then the driver can get
momentarily starved and some number of fields will be dropped.  That's
OK.  But if an odd number of fields get dropped, then that "first"
available buffer might be the bottom field and now we're stuck...

This patch fixes that problem by deliberately only setting up a single
field for one frame if we don't get a top field as the first available
buffer.  By purposely skipping the other field, then we only handle a
single buffer thus bringing things back into proper sync (i.e. top
field first) for the next frame.  To do this we just drop the few
lines in bttv_irq_next_video() that attempt to set up the second
buffer when that second buffer isn't for the bottom field.

This is definitely a problem in when in V4L2_FIELD_ALTERNATE mode.  In
the other modes this change either has no effect or doesn't harm
things any further anyway.

Subject: V4L/DVB (13170): bttv: Fix reversed polarity error when switching
 video standard

The bttv driver function which handles switching of the video standard
(set_tvnorm() in bttv-driver.c) includes a check which can optionally
also reset the cropping configuration to a default value.  It is
"optional" based on a comparison of the cropcap parameters of the
previous vs the newly requested video standard.  The comparison is
being done with a memcmp(), a function which only returns a true value
if the comparison actually fails.

This if-statement appears to have been written to assume wrong
memcmp() semantics.  That is, it was re-initializing the cropping
configuration only if the new video standard did NOT have different
cropcap values.  That doesn't make any sense.  One definitely should
reset things if the cropcap parameters are different - if there's any
comparison to made at all.

The effect of this problem was that a transition from, say, PAL to
NTSC would leave in place old cropping setup that made sense for the
PAL geometry but not for NTSC.  If the application doesn't care about
cropping it also won't try to reset the cropping configuration,
resulting in an improperly cropped video frame.  In the case I was
testing this actually caused black video frames to be displayed.

Another interesting effect of this bug is that if one does something
which does NOT change the video standard and this function is run,
then the cropping setup gets reset anyway - again because of the
backwards comparison.  It turns out that just running anything which
merely opens and closes the video device node (e.g. v4l-info) will
cause this to happen.  One can argue that simply opening the device
node and not doing anything to it should not mess with any of its
state - but because of this behavior, any TV app which does such
things (e.g. xawtv) probably therefore doesn't see the problem.

The solution is to fix the sense of the if-statement.  It's easy to
see how this mistake could have been made given how memcmp() works.
The patch is therefore removal of a single "!" character from the
if-statement in set_tvnorm in bttv-driver.c.

Subject: V4L/DVB (13190): em28xx: fix panic that can occur when starting audio
 streaming

Because the counters were not reset when starting up streaming, they would
be reused from the previous run.  This can result in cases such that when the
second instance of streaming starts up, the "cnt" variable in
em28xx_audio_isocirq() can end up being negative, resulting in attempting to
write to memory before the start of runtime->dma_area (as well as having a
negative number of bytes to copy).

Subject: V4L/DVB (13230): s2255drv: Don't conditionalize video buffer
 completion on waiting processes

The s2255 driver had logic which aborted processing of a video frame
if there was no process waiting on the video buffer in question.  That
simply doesn't work when the application is doing things in an
asynchronous manner.  If the application went to the trouble to queue
the buffer in the first place, then the driver should always attempt
to complete it - even if the application at that moment has its
attention turned elsewhere.  Applications which always blocked waiting
for I/O on the capture device would not have been affected by this.
Applications which *mostly* blocked waiting for I/O on the capture
device probably only would have been somewhat affected (frame lossage,
at a rate which goes up as the application blocks less).  Applications
which never blocked on the capture device (e.g. polling only) however
would never have been able to receive any video frames, since in that
case this "is anyone waiting on this?" check on the buffer never would
have evalutated true.  This patch just deletes that harmful check
against the buffer's wait queue.

Subject: V4L/DVB (13237): firedtv: length field corrupt in ca2host if
 length>127

This solves a problem in firedtv that has become major for Swedish DVB-T
users the last month or so.  It will most likely solve issues seen by
other users as well.

If the length of an AVC message is greater than 127, the length field
should be encoded in LV mode instead of V mode. V mode can only be used
if the length is 127 or less. This patch ensures that the CA_PMT
message is always encoded in LV mode so PMT message of greater lengths
can be supported.

Subject: V4L/DVB (13313): saa7134: add support for FORCE_TS_VALID mode for
 mpeg ts input

When FORCE_TS_VALID mode is enabled, the saa713x will accept MPEG TS input
without requiring TS_VALID set high.  This is required for some new boards
to function properly, due to the hardware design implementation.

The configuration is toggled within the board setup configuration.  Boards
that do not have this bit set will function as before with no change.

with interrupts enabled.

Disable interrupts before calling it from poll_all_shared_irqs().

Subject: [ARM] kirkwood: fix PCI I/O port assignment

Instead of allocating PCI devices I/O port bus addresses from the
000xxxxx I/O port range as intended, due to a bus versus physical
address mixup, the Kirkwood PCIe handling code inadvertently
allocated I/O port bus addresses from the f20xxxxx address range
(which is the physical address range of the PCIe I/O mapping window),
but then direct all I/O port accesses to bus addresses 000xxxxx,
which would then not be decoded at all.

Fix this by setting the base address of the PCIe I/O space struct
resource to KIRKWOOD_PCIE_IO_BUS_BASE instead of the incorrect
KIRKWOOD_PCIE_IO_PHYS_BASE, and fix up __io() to expect addresses
offsetted by the former instead of the latter.

(The suggested fix of directing I/O port accesses from the host to
bus addresses f20xxxxx instead has the problem that assigning full
32bit I/O port bus addresses (f20xxxxx) doesn't work on all PCI
devices, as not all PCI devices implement full 32 bit BAR registers
for I/O ports.  We should really try to allocate I/O port bus
addresses that fit in 16 bits.)

Subject: can: should not use __dev_get_by_index() without locks

bcm_proc_getifname() is called with RTNL and dev_base_lock
not held. It calls __dev_get_by_index() without locks, and
this is illegal (might crash)

Close the race by holding dev_base_lock and copying dev->name
in the protected section.

Subject: can: fix WARN_ON dump in net/core/rtnetlink.c:rtmsg_ifinfo()

On older kernels, e.g. 2.6.27, a WARN_ON dump in rtmsg_ifinfo()
is thrown when the CAN device is registered due to insufficient
skb space, as reported by various users. This patch adds the
rtnl_link_ops "get_size" to fix the problem. I think this patch
is required for more recent kernels as well, even if no WARN_ON
dumps are triggered. Maybe we also need "get_xstats_size" for
the CAN xstats.

Subject: nilfs2: fix kernel oops in error case of nilfs_ioctl_move_blocks

This fixes a kernel oops reported by Markus Trippelsdorf in the email
titled "[NILFS users] kernel Oops while running nilfs_cleanerd".

The oops was caused by a bug of error path in
nilfs_ioctl_move_blocks() function, which was inlined in
nilfs_ioctl_clean_segments().

nilfs_ioctl_move_blocks checks duplication of blocks which will be
moved in garbage collection.  But, the check should have be done
within nilfs_ioctl_move_inode_block() to prevent list corruption among
buffers storing the target blocks.

To fix the kernel oops, this moves forward the duplication check
before the list insertion.

I also tested this for stable trees [2.6.30, 2.6.31].

Subject: nilfs2: fix missing cleanup of gc cache on error cases

This fixes an -rc1 regression brought by the commit:
1cf58fa840472ec7df6bf2312885949ebb308853 ("nilfs2: shorten freeze
period due to GC in write operation v3").

Although the patch moved out a function call of
nilfs_ioctl_move_blocks() to nilfs_ioctl_clean_segments() from
nilfs_ioctl_prepare_clean_segments(), it didn't move corresponding
cleanup job needed for the error case.

This will move the missing cleanup job to the destination function.

Subject: x86/PCI: Adjust GFP mask handling for coherent allocations

Rather than forcing GFP flags and DMA mask to be inconsistent,
GFP flags should be determined even for the fallback device
through dma_alloc_coherent_mask()/dma_alloc_coherent_gfp_flags().

This restores 64-bit behavior as it was prior to commits
8965eb19386fdf5ccd0ef8b02593eb8560aa3416 and
4a367f3a9dbf2e7ffcee4702203479809236ee6e (not sure why there are
two of them), where GFP_DMA was forced on for 32-bit, but not
for 64-bit, with the slight adjustment that afaict even 32-bit
doesn't need this without CONFIG_ISA.

The perf_event_open() system call returns EACCES if the user is
not root which results in a very confusing error message:

  $ perf record -A -a -f

    Error: perfcounter syscall returned with -1 (Permission denied)

    Fatal: No CONFIG_PERF_EVENTS=y kernel support configured?

It turns out that's because perf tools are checking only for
EPERM. Fix that up to get a much better error message:

  $ perf record -A -a -f
    Fatal: Permission error - are you root?

Commit 6487a9d was an attempt some buffer head leaks in an ENOSPC
error path, but in some cases it actually results in an excess ENOSPC,
as shown above.  Fixing this means cleaning up who is responsible for
releasing the buffer heads from the callee to the caller of
add_dirent_to_buf().

Since that's a relatively complex change, and we're late in the rcX
development cycle, I'm reverting this now, and holding back a more
complete fix until after 2.6.32 ships.  We've lived with this
buffer_head leak on ENOSPC in ext3 and ext4 for a very long time; a
few more months won't kill us.

Subject: sh: Account for cache aliases in flush_icache_range()

The icache may also contain aliases so we must account for them just
like we do when manipulating the dcache. We usually get away with
aliases in the icache because the instructions that are read from memory
are read-only, i.e. they never change. However, the place where this
bites us is when the code has been modified.

Subject: intel-iommu: Check for 'DMAR at zero' BIOS error earlier.

Chris Wright has some patches which let us fall back to swiotlb nicely
if IOMMU initialisation fails. But those are a bit much for 2.6.32.

Instead, let's shift the check for the biggest problem, the HP and Acer
BIOS bug which reports a DMAR at physical address zero. That one can
actually be checked much earlier -- before we even admit to having
detected an IOMMU in the first place. So the swiotlb init goes ahead as
we want.

Subject: highmem: Fix race in debug_kmap_atomic() which could cause warn_count
 to underflow

debug_kmap_atomic() tries to prevent ever printing more than 10
warnings, but it does so by testing whether an unsigned integer
is equal to 0. However, if the warning is caused by a nested
IRQ, then this counter may underflow and the stream of warnings
will never end.

Fix that by using a signed integer instead.

Subject: ALSA: hda - Tweak OLPC XO-1.5 microphone bias

Our contacts at Conexant suggested that we reduce the external
microphone bias to 50% in order to center the input signal with
the DC input range of the codec. This is because the microphone
port is DC coupled for potential use with sensors.

Subject: sound: rawmidi: fix double init when opening MIDI device with
 O_APPEND

Commit 9a1b64caac82aa02cb74587ffc798e6f42c6170a in 2.6.30 moved the
substream initialization code to where it would be executed every time
the substream is opened.

This had the consequence that any further opening would drop and leak
the data in the existing buffer, and that the device driver's open
callback would be called multiple times, unexpectedly.

Commit 9a1b64caac82aa02cb74587ffc798e6f42c6170a in 2.6.30 dropped the
check that a substream must already have been opened with O_APPEND to be
able to open it a second time.

This would make it possible for a substream to be switched to append
mode, which would mean that non-atomic writes would fail unexpectedly.

Subject: sound: rawmidi: fix MIDI device O_APPEND error handling

Commit 9a1b64caac82aa02cb74587ffc798e6f42c6170a in 2.6.30 broke the
error handling code in rawmidi_open_priv().

If only the output substream of a RawMIDI device has been opened and
if this device is then opened with O_RDWR | O_APPEND and if the
initialization of the input substream fails (either because of low
memory or because the device driver's open callback fails), then the
runtime structure of the already open output substream will be freed
and all following writes through the first handle will cause
snd_rawmidi_write() to use the NULL runtime pointer.

The scan function was using 32 bit access which does not
work on 16bit CF cards.

This patch corrects this by doing two 16 bit reads like
ssb_pcmcia_read32 already does.

mb -- Removed locking. That early in init there's no need for locking.

Subject: b43: work around a locking issue in ->set_tim()

ops->set_tim() must be atomic, so b43 trying to acquire a mutex leads
to a kernel crash. This patch trades an easy to trigger crash in AP
mode for an unlikely race condition. According to Michael, the real
fix would be to allow set_tim() to sleep, since b43 is not the only
driver that needs to sleep in all callbacks.

Although I have always been the active maintainer of the rt2x00 drivers,
I was not mentioned explicitely in the MAINTAINERS file as such.

Update the rt2x00 entry in the MAINTAINERS file to add my name and

Subject: ath5k: don't reset mcast filter when configuring the mode

We should not zero out the multicast hash when configuring
the operating mode, since a zero value means all multicast
frames will get dropped.  Also, ath5k_mode_setup() gets
called after any reset, so the hash already set up in
configure_filter() is lost.

Subject: iwlwifi: Use RTS/CTS as the preferred protection mechanism for 6000
 series

When 802.11g was introduced, we had RTS/CTS and CTS-to-Self protection
mechanisms. In an HT Beacon, HT stations use the "Operating Mode" field
in the HT Information Element to determine whether or not to use
protection.

The Operating Mode field has 4 possible settings: 0-3:
Mode 0: If all stations in the BSS are 20/40 MHz HT capable, or if the
BSS is 20/40 MHz capable, or if all stations in the BSS are 20 MHz HT
stations in a 20 MHz BSS
Mode 1: used if there are non-HT stations or APs using the primary or
secondary channels
Mode 2: if only HT stations are associated in the BSS and at least one
20 MHz HT station is associated.
Mode 3: used if one or more non-HT stations are associated in the BSS.

When in operating modes 1 or 3, and the Use_Protection field is 1 in the
Beacon's ERP IE, all HT transmissions must be protected using RTS/CTS or
CTS-to-Self.

By default, CTS-to-self is the preferred protection mechanism for less
overhead and higher throughput; but using the full RTS/CTS will better
protect the inner exchange from interference, especially in
highly-congested environment.

For 6000 series WIFI NIC, RTS/CTS protection mechanism is the
recommended choice for HT traffic based on the HW design.

omap_request_dma()/omap_free_dma() simultaneously

pasemi_defconfig hasn't been updated for a year.

Mostly a refresh of defaults, but this also disables 64K pages.

From bf3204cbff7d2606e758afb0994e8da6ae1c6c26 Mon Sep 17 00:00:00 2001

Subject: Input: fix locking in memoryless force-feedback devices

Now that input core acquires dev->event_lock spinlock and disables
interrupts when propagating input events, using spin_lock_bh() in
ff-memless driver is not allowed. Actually, the timer_lock itself
is not needed anymore, we should simply use dev->event_lock
as well.

Also do a small cleanup in force-feedback core.

Subject: ALSA: hda - possible read past array alc88[02]_parse_auto_config()

The test of index `i' is after the read - too late - and
unsafe: if snd_hda_get_connections() fails in the last
iteration a read beyond the array is possible.

Subject: NFSv4: Fix a cache validation bug which causes getcwd() to return
 ENOENT

Changeset a65318bf3afc93ce49227e849d213799b072c5fd (NFSv4: Simplify some
cache consistency post-op GETATTRs) incorrectly changed the getattr
bitmap for readdir().
This causes the readdir() function to fail to return a
fileid/inode number, which again exposed a bug in the NFS readdir code that
causes spurious ENOENT errors to appear in applications (see
http://bugzilla.kernel.org/show_bug.cgi?id=14541).

The immediate band aid is to revert the incorrect bitmap change, but more
long term, we should change the NFS readdir code to cope with the
fact that NFSv4 servers are not required to support fileids/inode numbers.

Subject: ext3: retry failed direct IO allocations

On a 256M 4k block filesystem, doing this in a loop:

    dd if=/dev/zero of=test oflag=direct bs=1M count=64
    rm -f test

eventually leads to spurious ENOSPC:

    dd: writing `test': No space left on device

As with other block allocation callers, it looks like we need to
potentially retry the allocations on the initial ENOSPC.

A similar patch went into ext4 (commit
fbbf69456619de5d251cb9f1df609069178c62d5)

Subject: ext3: Wait for proper transaction commit on fsync

We cannot rely on buffer dirty bits during fsync because pdflush can come
before fsync is called and clear dirty bits without forcing a transaction
commit. What we do is that we track which transaction has last changed
the inode and which transaction last changed allocation and force it to
disk on fsync.

Subject: omap: Fix omapfb/lcdc on OMAP1510 broken when PM set

With CONFIG_PM=y, the omapfb/lcdc device on Amstrad Delta, after initially
starting correctly, breaks with the following error messages:

omapfb omapfb: resetting (status 0xffffff96,reset count 1)
...
omapfb omapfb: resetting (status 0xffffff96,reset count 100)
omapfb omapfb: too many reset attempts, giving up.

Looking closer at this I have found that it had been broken almost 2 years ago
with commit 2418996e3b100114edb2ae110d5d4acb928909d2, PM fixes for OMAP1.

The definite reason for broken omapfb/lcdc behavoiur in PM mode
appeared to be ARM_IDLECT1:IDLIF_ARM (bit 6) put into idle regardless of LCD
DMA possibly running. The bit were set based on return value of the
omap_dma_running() function that did not check for dedicated LCD DMA
channel status. The patch below fixes this.

Note that the hardcoded register value will be fixed during the next merge
cycle to use OMAP_LCDC_ defines. Currently the OMAP_LCDC_ defines are local
to drivers/video/omap/lcdc.c, so let's not start moving those right now.

Created against linux-2.6.32-rc6

Tested on Amstrad Delta

Subject: omap3: pandora: Fix keypad keymap

The original TWL4030 keypad driver from linux-omap used KEY()
macro defined as (col, row), but while it was merged upstream
it was changed to use matrix keypad infrastructure, which uses
(row, col) format. Update the keymap in board file to match
layout of mainline driver.

Subject: Btrfs: fix data allocation hint start

Sometimes our start allocation hint when we cow a file can be either
EXTENT_HOLE or some other such place holder, which is not optimal.  So if we
find that our em->block_start is one of these special values, check to see
where the first block of the inode is stored, and use that as a hint.  If that
block is also a special value, just fallback on a hint of 0 and let the
allocator figure out a good place to put the data.

Subject: Btrfs: cleanup transaction starting and fix journal_info usage

We use journal_info to tell if we're in a nested transaction to make sure we
don't commit the transaction within a nested transaction.  We use another
method to see if there are any outstanding ioctl trans handles, so if we're
starting one do not set current->journal_info, since it will screw with other
filesystems.  This patch also cleans up the starting stuff so there aren't any
magic numbers.

Subject: Btrfs: fix how we set max_size for free space clusters

This patch fixes a problem where max_size can be set to 0 even though we
filled the cluster properly.  We set max_size to 0 if we restart the cluster
window, but if the new start entry is big enough to be our new cluster then we
could return with a max_size set to 0, which will mean the next time we try to
allocate from this cluster it will fail.  So set max_extent to the entry's
size.  Tested this on my box and now we actually allocate from the cluster
after we fill it.  Thanks,

Subject: Btrfs: find ideal block group for caching

This patch changes a few things.  Hopefully the comments are helpfull, but
I'll try and be as verbose here.

Problem:

My fedora box was taking 1 minute and 21 seconds to boot with btrfs as root.
Part of this problem was we pick the first block group we can find and start
caching it, even if it may not have enough free space.  The other problem is
we only search for cached block groups the first time around, which we won't
find any cached block groups because this is a newly mounted fs, so we end up
caching several block groups during bootup, which with alot of fragmentation
takes around 30-45 seconds to complete, which bogs down the system.  So

Solution:

1) Don't cache block groups willy-nilly at first.  Instead try and figure out
which block group has the most free, and therefore will take the least amount
of time to cache.

2) Don't be so picky about cached block groups.  The other problem is once
we've filled up a cluster, if the block group isn't finished caching the next
time we try and do the allocation we'll completely ignore the cluster and
start searching from the beginning of the space, which makes us cache more
block groups, which slows us down even more.  So instead of skipping block
groups that are not finished caching when we have a hint, only skip the block
group if it hasn't started caching yet.

There is one other tweak in here.  Before if we allocated a chunk and still
couldn't find new space, we'd end up switching the space info to force another
chunk allocation.  This could make us end up with way too many chunks, so keep
track of this particular case.

With this patch and my previous cluster fixes my fedora box now boots in 43
seconds, and according to the bootchart is not held up by our block group
caching at all.

Subject: Btrfs: fallback on uncompressed io if compressed io fails

Currently compressed IO does not deal with not having its entire extent able to
be allocated.  So if we have enough free space to allocate for the extent, but
its not contiguous, it will fail spectacularly.  This patch fixes this by
falling back on uncompressed IO which lets us spread the delalloc extent across
multiple extents.  I tested this by making us randomly think the reservation had
failed to make it fallback on the uncompressed io way and it seemed to work
fine.  Thanks,

Subject: Btrfs: allow more metadata chunk preallocation

On an FS where all of the space has not been allocated into chunks yet,
the enospc can return enospc just because the existing metadata chunks
are full.

We get around this by allowing more metadata chunks to be allocated up
to a certain limit, and finding the right limit is a little fuzzy.  The
problem is the reservations for delalloc would preallocate way too much
of the FS as metadata.  We need to start saying no and just force some
IO to happen.

But we also need to let a reasonable amount of the FS become metadata.
This bumps the hard limit up, later releases will have a better system.

Subject: Btrfs: fix panic when trying to destroy a newly allocated

There is a problem where iget5_locked will look for an inode, not find it, and
then subsequently try to allocate it.  Another CPU will have raced in and
allocated the inode instead, so when iget5_locked gets the inode spin lock again
and does a search, it finds the new inode.  So it goes ahead and calls
destroy_inode on the inode it just allocated.  The problem is we don't set
BTRFS_I(inode)->root until the new inode is completely initialized.  This patch
makes us set root to NULL when alloc'ing a new inode, so when we get to
btrfs_destroy_inode and we see that root is NULL we can just free up the memory
and continue on.  This fixes the panic

Subject: btusb bluetooth driver: wait for 'waker' work too before closing

Rafael debugged a resume-time hang (with oopses in workqueue handling)
on his laptop that was due to the 'waker' workqueue entry being
disconnected and then released without the workqueue entry having been
synchronized.

Several people were involved, with Oleg Nesterov doing a debugging patch
showing what workqueue entry was corrupt etc.

This was a regression introduced by commit 7bee549e19 ("Bluetooth: Add
USB autosuspend support to btusb driver") as Rafael points out (not
actually bisected, but it became clear once the bug was found).

Subject: omap3: Decrease cpufreq transition latency

Adjust OMAP3 frequency transition latency from 10,000,000uS to a more
reasonable 300,000uS.  This causes ondemand and conservative governors to
sample CPU load more often resulting in more responsive behavior.

Tested on Android 2.6.29; using this value and conservative governor, CORE
power consumption on Zoom2 was comparable to the old and unresponsive
10,000,000uS value while UI responsiveness was greatly improved.

Subject: md: factor out updating of 'recovery_offset'.

Each device has its own 'recovery_offset' showing how far
recovery has progressed on the device.
As the only real significance of this is that fact that it can
be stored in the metadata and recovered at restart, and as
only 1.x metadata can do this, we were only updating
'recovery_offset' to 'curr_resync_completed' when updating
v1.x metadata.
But this is wrong, and we will shortly make limited use of this
field in v0.90 metadata.

So move the update into common code.

Subject: intel-iommu: Obey coherent_dma_mask for alloc_coherent on passthrough

The model for IOMMU passthrough is that decent devices that can cope
with DMA to all of memory get passthrough; crappy devices with a limited
dma_mask don't -- they get to use the IOMMU anyway.

This is done on the basis that IOMMU passthrough is usually wanted for
performance reasons, and it's only the decent PCI devices that you
really care about performance for, while the crappy 32-bit ones like
your USB controller can just use the IOMMU and you won't really care.

Unfortunately, the check for this was only looking at dev->dma_mask, not
at dev->coherent_dma_mask. And some devices have a 32-bit
coherent_dma_mask even though they have a full 64-bit dma_mask.

Even more unfortunately, fixing that simple oversight would upset
certain broken HP devices. Not only do they have a 32-bit
coherent_dma_mask, but they also have a tendency to do stray DMA to
unmapped addresses. And then they die when they take the DMA fault they
so richly deserve.

So if we do the 'correct' fix, it'll mean that affected users have to
disable IOMMU support completely on "a large percentage of servers from
a major vendor."

Personally, I have little sympathy -- given that this is the _same_
'major vendor' who is shipping machines which claim to have IOMMU
support but have obviously never _once_ booted a VT-d capable OS to do
any form of QA. But strictly speaking, it _would_ be a regression even
though it only ever worked by fluke.

For 2.6.33, we'll come up with a quirk which gives swiotlb support
for this particular device, and other devices with an inadequate
coherent_dma_mask will just get normal IOMMU mapping.

The simplest fix for 2.6.32, though, is just to jump through some hoops
to try to allocate coherent DMA memory for such devices in a place that
they can reach. We'd use dma_generic_alloc_coherent() for this if it
existed on IA64.

Subject: intel-iommu: Support PCIe hot-plug

To support PCIe hot plug in IOMMU, we register a notifier to respond to device
change action.

When the notifier gets BUS_NOTIFY_UNBOUND_DRIVER, it removes the device
from its DMAR domain.

A hot added device will be added into an IOMMU domain when it first does IOMMU
op. So there is no need to add more code for hot add.

Without the patch, after a hot-remove, a hot-added device on the same
slot will not work.

Subject: Thaw refrigerated bdi flusher threads before invoking kthread_stop on
 them

Unfreezes the bdi flusher task when the said task needs to exit.

Steps to reproduce this.
1) Mount a file system from MMC/SD card.
2) Unmount the file system. This creates a flusher task.
3) Attempt suspend to RAM. System is unresponsive.

This is because the bdi flusher thread is already in the refrigerator and will
remain so until it is thawed. The MMC driver suspend routine call stack will
ultimately issue a 'kthread_stop' on the bdi flusher thread and will block
until the flusher thread is exited. Since the bdi flusher thread is in the
refrigerator it never cleans up until thawed.

Subject: page allocator: always wake kswapd when restarting an allocation
 attempt after direct reclaim failed

If a direct reclaim makes no forward progress, it considers whether it
should go OOM or not.  Whether OOM is triggered or not, it may retry the
allocation afterwards.  In times past, this would always wake kswapd as
well but currently, kswapd is not woken up after direct reclaim fails.
For order-0 allocations, this makes little difference but if there is a
heavy mix of higher-order allocations that direct reclaim is failing for,
it might mean that kswapd is not rewoken for higher orders as much as it
did previously.

This patch wakes up kswapd when an allocation is being retried after a
direct reclaim failure.  It would be expected that kswapd is already
awake, but this has the effect of telling kswapd to reclaim at the higher
order as well.

Subject: page allocator: Do not allow interrupts to use ALLOC_HARDER

Commit 341ce06f69abfafa31b9468410a13dbd60e2b237 ("page allocator:
calculate the alloc_flags for allocation only once") altered watermark
logic slightly by allowing rt_tasks that are handling an interrupt to set
ALLOC_HARDER.  This patch brings the watermark logic more in line with
2.6.30.

This change results in a reduction of the number high-order GFP_ATOMIC
allocation failures reported.  See

Subject: fb: remove fb_save_state() and fb_restore_state operations

Remove fb_save_state() and fb_restore_state operations from frame buffer layer.
They are used only in two drivers:
1. savagefb  - and cause bug #11248
2. uvesafb

Usage of these operations is misunderstood in both drivers so kill these
operations, fix the bug #11248 and avoid confusion in the future.

Tested on Savage 3D/MV card and the patch fixes the bug #11248.

The frame buffer layer uses these funtions during switch between graphics
and text mode of the console, but these drivers saves state before
switching of the frame buffer (in the fb_open) and after releasing it (in
the fb_release).  This defeats the purpose of these operations.

Addresses http://bugzilla.kernel.org/show_bug.cgi?id=11248

Fix wrong bit mask for blanking register.  Due to the error a CRT monitor
blanks off due to wrong frequency (out of range) instead of PM signal
(vertical and horizontal frequencies cut off).

Just compare the mask with bits set in the switch(blank) clause below the
changed line.

Subject: memcg: fix wrong pointer initialization at page migration when memcg
 is disabled.

Lee Schermerhorn reported that he saw bad pointer dereference in
mem_cgroup_end_migration() when he disabled memcg by boot option.

memcg's page migration logic works as

	mem_cgroup_prepare_migration(page, &ptr);
	do page migration
	mem_cgroup_end_migration(page, ptr);

Now, ptr is not initialized in prepare_migration when memcg is disabled
by boot option. This causes panic in end_migration. This patch fixes it.

    Note that .data.page_aligned and .data.cacheline_aligned are now after
    _data; it was probably a bug that they were before it.

    Also, some explicit ALIGN(8)'s between various initcall sections were
    removed; this should be harmless as the implicit alignment of
    initcall_t was already 8.

Subject: pidns: fix a leak in /proc dentries and inodes with pid namespaces.

Daniel Lezcano reported a leak in 'struct pid' and 'struct pid_namespace'
that is discussed in:

	http://lkml.org/lkml/2009/10/2/159.

To summarize the thread, when container-init is terminated, it sets the
PF_EXITING flag, zaps other processes in the container and waits to reap
them.  As a part of reaping, the container-init should flush any /proc
dentries associated with the processes.  But because the container-init is
itself exiting and the following PF_EXITING check, the dentries are not
flushed, resulting in leak in /proc inodes and dentries.

This fix reverts the commit 7766755a2f249e7e0 ("Fix /proc dcache deadlock
in do_exit") which introduced the check for PF_EXITING.  At the time of
the commit, shrink_dcache_parent() flushed dentries from other filesystems
also and could have caused a deadlock which the commit fixed.  But as
pointed out by Eric Biederman, after commit 0feae5c47aabdde59,
shrink_dcache_parent() no longer affects other filesystems.  So reverting
the commit is now safe.

As pointed out by Jan Kara, the leak is not as critical since the
unclaimed space will be reclaimed under memory pressure or by:

	echo 3 > /proc/sys/vm/drop_caches

But since this check is no longer required, its best to remove it.

Subject: fs: add missing compat_ptr handling for FS_IOC_RESVSP ioctl

For FS_IOC_RESVSP and FS_IOC_RESVSP64 compat_sys_ioctl() uses its
arg argument as a pointer to userspace. However it is missing a
a call to compat_ptr() which will do a proper pointer conversion.

This was introduced with 3e63cbb1 "fs: Add new pre-allocation ioctls
to vfs for compatibility with legacy xfs ioctls".

at91sam9g45 non ES lots have an alternate pixel clock calculation formula.
Introduce this one with condition on the cpu_is_xxxxx() macros.

Newer 9g45 SOC will not have good pixel clock calculation without this

Subject: rtc: v3020: fix v3020_mmio_read_bit()

v3020_mmio_read_bit() always returns 0 when left_shift > 7.

v3020_mmio_read_bit()'s return type is (unsigned char).  The code returns
a value masked by (1 << left_shift) that is casted to the return type.  If
left_shift is larger than 7, the cast will always result in a 0 return
value.  The problem was discovered with left_shift = 16, and the included
patch corrects the problem.

The bug was introduced in the last (Apr 3 2009) commit of the file, kernel
versions 2.6.30 and later.

Subject: gpiolib: fix device_create() result check

In case of failure, device_create() returns not NULL but the error code.
The current code checks for non-NULL though which causes kernel oops in
sysfs_create_group() when device_create() fails.  Check for error using
IS_ERR() and propagate the error value using PTR_ERR() instead of fixed
-ENODEV code returned now...

Subject: pps: events reporting fix up

PPS events must be recorded according to PPS's mode settings.

If a process asks for (i.e.) capture-assert events only, when the PPS
client calls the pps_event() function to save the current PPS event, we
should verify the event type and then discard unwanted ones.

Also, without this patch userland processes waiting for a specific PPS
event (assert or clear but not both) may be awakened at wrong time.

Subject: __generic_block_fiemap(): fix for files bigger than 4GB

Because of an integer overflow on start_blk, various kind of wrong results
would be returned by the generic_block_fiemap() handler, such as no
extents when there is a 4GB+ hole at the beginning of the file, or wrong
fe_logical when an extent starts after the first 4GB.

Subject: percpu: restructure pcpu_extend_area_map() to fix bugs and improve
 readability

pcpu_extend_area_map() had the following two bugs.

* It should return 1 if pcpu_lock was dropped and reacquired but it
  returned 0.  This could lead to oops if free_percpu() races with
  area map extension.

* pcpu_mem_free() was called under pcpu_lock.  pcpu_mem_free() might
  end up calling vfree() which isn't IRQ safe.  This could lead to
  deadlock through lock order inversion via IRQ.

In addition, Linus pointed out that the temporary lock dropping and
subtle three-way return value of pcpu_extend_area_map() was very ugly
and suggested to split the function into two - pcpu_need_to_extend()
and pcpu_extend_area_map().

This patch restructures pcpu_extend_area_map() as suggested and fixes
the two bugs.

Subject: md: allow v0.91 metadata to record devices as being active but not
 in-sync.

This is a combination that didn't really make sense before.
However when a reshape is converting e.g. raid5 -> raid6, the extra
device is not fully in-sync, but is certainly active and contains
important data.
So allow that start to be meaningful and in particular get
the 'recovery_offset' value (which is needed for any non-in-sync
active device) from the reshape_position.

Subject: Don't unconditionally set in_sync on newly added device in
 raid5_reshape

When a reshape finds that it can add spare devices into the array,
those devices might already be 'in_sync' if they are beyond the old
size of the array, or they might not if they are within the array.

The first case happens when we change an N-drive RAID5 to an
N+1-drive RAID5.
The second happens when we convert an N-drive RAID5 to an
N+1-drive RAID6.

So set the flag more carefully.
Also, ->recovery_offset is only meaningful when the flag is clear,
so only set it in that case.

This change needs the preceding two to ensure that the non-in_sync
device doesn't get evicted from the array when it is stopped, in the
case where v0.90 metadata is used.

Subject: md/raid5: Allow dirty-degraded arrays to be assembled when only party
 is degraded.

Normally is it not safe to allow a raid5 that is both dirty and
degraded to be assembled without explicit request from that admin, as
it can cause hidden data corruption.
This is because 'dirty' means that the parity cannot be trusted, and
'degraded' means that the parity needs to be used.

However, if the device that is missing contains only parity, then
there is no issue and assembly can continue.
This particularly applies when a RAID5 is being converted to a RAID6
and there is an unclean shutdown while the conversion is happening.

So check for whether the degraded space only contains parity, and
in that case, allow the assembly.

Subject: Input: force LED reset on resume

We should be sending EV_LED event down to drivers upon resume even in cases
when in-kernel state of the LED is off since device could come up with some
leds turned on.

Subject: Input: atkbd - restore LED state at reconnect

Even though input core tells us to restore LED state and repeat rate
at resume keyboard may be reconnected either by request from userspace
(via sysfs) or just by pulling it from the box and plugging it back in.
In these cases we still need to restore state ourselves.

Subject: cciss: make device attrs static

No need to export those device attributes.

In fact, without this patch, we can trip over a build error if cciss
is a built-in and another driver also declares and exports attributes
with the same name.

You'll see errors like:

	drivers/scsi/built-in.o: multiple definition of `dev_attr_lunid'
	drivers/block/built-in.o: first defined here

 CONFIG_PXA_HAVE_ISA_IRQS=y

Commit d2c37068429b29d6549cf3486fc84b836689e122 ([ARM] pxa:
initialize default interrupt priority and use ICHP for IRQ handling)
broke ISA interrupt support on pxa27x/3xx.

In such a case, PXA_IRQ(0) != 0, and the IRQ number computed from
ICHP must be offset by PXA_IRQ(0).

Tested on an Arcom Zeus (pxa270), with both CONFIG_PXA_HAVE_ISA_IRQS
enabled and disabled.

The monreader device driver doesn't set dev->driver_data to NULL after
freeing the corresponding data structure. This leads to a use after
free bug in the freeze/thaw suspend/resume functions after the device
has been opened and closed once. Fix this by clearing dev->driver_data

Subject: [S390] reset cputime accounting after IPL from NSS

After an IPL from NSS the uptime of the system is incorrect. The reason
is that the startup code in head.S is not executed in case of an IPL
from NSS. Due to that sched_clock_base_cc which is used to initialze
wall_to_monotonic contains the time stamp when the NSS has been created
instead of the time stamp of the system start.

Reinitialize the cputime accounting values in create_kernel_nss after
the SAVESYS CP command that created the NSS segment.

In a system where the ctrl-alt-del init action initiated by signal
quiesce suspends the machine the quiesce handler override for
_machine_restart, _machine_halt and _machine_power_off needs to be
undone, otherwise the override is still present in the resumed
system. The next shutdown would then load the quiesce state psw
instead of performing the correct shutdown action.

Subject: [S390] s390: fix single stepping on svc0

On s390 there are two ways of specifying the system call number for
the svc instruction. The standard way is to use the immediate field
in the instruction (or to use EXecute for values unknown during
assemble time). This can encode 256 system calls.
The kernel ABI also allows to put the system call number in r1 and
then execute svc 0 to enable system call numbers > 255.

It turns out that single stepping svc 0 is broken, since the PER
program check handler uses r1. We have to use a different register.

Subject: MIPS: Fix emulation of 64-bit FPU on FPU-less 64-bit CPUs.

Running a 64-bit kernel on a 64-bit CPU without an FPU would cause the
emulator to run in 32-bit mode.  The c0_Status.FR bit is wired to zero
on systems without an FPU, so using that bit to decide how the emulator
behaves doesn't allow for proper emulation on 64-bit FPU-less
processors.

Instead, we need to select the emulator mode based on the user-space
ABI.  Since the thread flag TIF_32BIT_REGS is used to set c0_Status.FR,
we can just use it to decide if the emulator should be in 32-bit or
64-bit mode.

Although current users of such array variables are all early bootstrap
code and not likely to cause real stack overflow (thread_info corruption),
it is preferable to  to declare these arrays static with __initdata.

Subject: MIPS: SMTC: Fix lockup in smtc_distribute_timer

1. At the end of smtc_distribute_timer, nextstamp is valid and has already
   passed so we goto repeat.
2. Nothing updates nextstamp (only updated if the timeout is in the future
   And we just decided it is in the past)
3. At the end nextstamp still has the same value so it is still valid and
   in the past.
4. This repeats until read_c0_count has a value which causes nextstamp to
   be in the future.

Reported and initial patch and testing  by Mikael Starvik

Subject: [ARM] Kirkwood: disable propagation of mbus error to the CPU local
 bus

Disable propagation of mbus errors to the CPU local bus, as this causes
mbus errors (which can occur for example for PCI aborts) to throw CPU
aborts, which we're not set up to deal with.

Subject: tcp: provide more information on the tcp receive_queue bugs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The addition of rcv_nxt allows to discern whether the skb
was out of place or tp->copied. Also catch fancy combination
of flags if necessary (sadly we might miss the actual causer
flags as it might have already returned).

Btw, we perhaps would want to forward copied_seq in
somewhere or otherwise we might have some nice loop with
WARN stuff within but where to do that safely I don't
know at this stage until more is known (but it is not
made significantly worse by this patch).

Subject: Revert "libipw: initiate cfg80211 API conversion"

This reverts commit b8ecd988b1670035a05035c553c08331214d6603.

Due to poor API call balancing by me, this commit not only broke ipw2200
if it can't find it's firmware, it broke ipw2100 basically anytime you
removed the module.  At this point in the cycle, let's just put it back
to a sane state and try again next time...

Subject: SUNRPC: Address buffer overrun in rpc_uaddr2sockaddr()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The size of buf[] must account for the string termination needed for
the first strict_strtoul() call.  Introduced in commit a02d6926.

Fábio Olivé Leite points out that strict_strtoul() requires _either_
'\n\0' _or_ '\0' termination, so use the simpler '\0' here instead.

See http://bugzilla.kernel.org/show_bug.cgi?id=14546 .

Subject: sctp: Set source addresses on the association before adding
 transports

Recent commit 8da645e101a8c20c6073efda3c7cc74eec01b87f
	sctp: Get rid of an extra routing lookup when adding a transport
introduced a regression in the connection setup.  The behavior was

different between IPv4 and IPv6.  IPv4 case ended up working because the
route lookup routing returned a NULL route, which triggered another
route lookup later in the output patch that succeeded.  In the IPv6 case,
a valid route was returned for first call, but we could not find a valid
source address at the time since the source addresses were not set on the
association yet.  Thus resulted in a hung connection.

The solution is to set the source addresses on the association prior to
adding peers.

Subject: sctp: Fix regression introduced by new sctp_connectx api

A new (unrealeased to the user) sctp_connectx api

c6ba68a26645dbc5029a9faa5687ebe6fcfc53e4
    sctp: support non-blocking version of the new sctp_connectx() API

introduced a regression cought by the user regression test
suite.  In particular, the API requires the user library to
re-allocate the buffer and could potentially trigger a SIGFAULT.

This change corrects that regression by passing the original
address buffer to the kernel unmodified, but still allows for
a returned association id.

Recent commits
	sctp: Get rid of an extra routing lookup when adding a transport
and
	sctp: Set source addresses on the association before adding transports

changed when routes are added to the sctp transports.  As such,
we didn't set the socket source address correctly when adding the first
transport.  The first transport is always the primary/active one, so
when adding it, set the socket source address.  This was causing
regression failures in SCTP tests.

Due commit 4b77b0a2ba27d64f58f16d8d4d48d8319dda36ff, it is not more
possible to pci_restore_state() more than once without calling
pci_save_state() in the middle.

Actually running a ethtool test on s2io makes the card inactive,
and it needs to unload/reload the module to fix.

This patch just save the state just after it restore in order to
keep the old behaviour

Subject: can: Fix driver Kconfig structure

In 2.6.32-rc the new EMS USB CAN driver was contributed and added the Kconfig
entry right behind an entry of the same *vendor*. This teared the SJA1000
based driver selection into pieces.

This fix cleans up the 2.6.32-rc Kconfig files for the CAN drivers and moves
the SJA1000 and USB Kconfig portions into the belonging directories.

As there are many new CAN drivers in the queue getting this cleanup into
2.6.32-rc would massively reduce the problems for the upcoming drivers.

Thanks,
Oliver

Subject: r8169: Fix receive buffer length when MTU is between 1515 and 1536

In r8169 driver MTU is used to calculate receive buffer size.
Receive buffer size is used to configure hardware incoming packet filter.

For jumbo frames:
Receive buffer size = Max frame size = MTU + 14 (ethernet header) + 4
(vlan header) + 4 (ethernet checksum) = MTU + 22

Bug:
driver for all MTU up to 1536 use receive buffer size 1536

As you can see from formula, this mean all IP packets > 1536 - 22
(for vlan tagged, 1536 - 18 for not tagged) are dropped by hardware
filter.

Example:

host_good>  ifconfig eth0 mtu 1536
host_r8169> ifconfig eth0 mtu 1536
host_good>  ping host_r8169
Ok
host_good>  ping -s 1500 host_r8169
Fail
host_good>  ifconfig eth0 mtu 7000
host_r8169> ifconfig eth0 mtu 7000
host_good>  ping -s 1500 host_r8169
Ok

Bonus: got rid of magic number 8

Subject: Fix memory corruption caused by nfsd readdir+

Commit 8177e6d6dfb9cd03d9bdeb647c32161f8f58f686 ("nfsd: clean up
readdirplus encoding") introduced single character typo in nfs3 readdir+
implementation.  Unfortunately that typo has quite bad side effects:
random memory corruption, followed (on my box) with immediate
spontaneous box reboot.

Using 'p1' instead of 'p' fixes my Linux box rebooting whenever VMware
ESXi box tries to list contents of my home directory.

Subject: fix memory leak in fixed btusb_close

If the waker is killed before it can replay outstanding URBs, these URBs
won't be freed or will be replayed at the next open.  This patch closes
the window by explicitely discarding outstanding URBs.

Subject: genksyms: Mark is_reserved_word static

The genksyms keyword gperf hash provides a function is_reserved_word.
genksyms #includes the resulting generated file keywords.c, so the
function gets used only in the same source file that defines it.  Mark
is_reserved_word static, and regenerate the corresponding generated
file.

Subject: dtc: Set "noinput" in the lexer to avoid an unused function

Regenerate the corresponding generated lexer.

Regenerating the lexer with current flex also provides prototypes for
various yy* functions, making some -Wmissing-prototypes warnings go away
as well.

Now that all host programs use static for all private functions and

Subject: Bluetooth: Set general bonding security for ACL by default

This patch fixes double pairing issues with Secure Simple
Paring support. It was observed that when pairing with SSP
enabled, that the confirmation will be asked twice.

http://www.spinics.net/lists/linux-bluetooth/msg02473.html

This also causes bug when initiating SSP connection from
Windows Vista.

The reason is because bluetoothd does not store link keys
since HCIGETAUTHINFO returns 0. Setting default to general
bonding fixes these issues.

The default mode for SOCK_SEQPACKET is Basic Mode. So when no

This is important for current application to keep working as

Subject: Bluetooth: Fix regression with L2CAP configuration in Basic Mode

Basic Mode is the default mode of operation of a L2CAP entity. In
this case the RFC (Retransmission and Flow Control) configuration
option should not be used at all.

Normally remote L2CAP implementation should just ignore this option,
but it can cause various side effects with other Bluetooth stacks
that are not capable of handling unknown options.

Subject: ALSA: ice1724 - make some bitfields unsigned

This is a clean up and doesn't change the behavior.

Bit fields should always be unsigned.  Otherwise pm_suspend_enabled will
be -1 when you want it to be 1.  The other bad thing is that the sparse
checker will complain 36 times if they aren't unsigned.

The other bitfields in that struct are unsigned already.

If ret is unsigned, the checks for negative wm831x_reg_read() return values
are wrong. The error value should be transmitted to its caller, e.g.
wm831x_gp_ldo_get_status() which tests for a negative return value.

Subject: net: Fix the rollback test in dev_change_name()

net: Fix the rollback test in dev_change_name()

In dev_change_name() an err variable is used for storing the original
call_netdevice_notifiers() errno (negative) and testing for a rollback
error later, but the test for non-zero is wrong, because the err might
have positive value as well - from dev_alloc_name(). It means the
rollback for a netdevice with a number > 0 will never happen. (The err
test is reordered btw. to make it more readable.)

read.

Subject: hwmon: (adt7475) Fix temperature fault flags

The logic of temperature fault flags is wrong, it shows faults when
there are none and vice versa. Fix it.

I can't believe this has been broken since the driver was added, 8
months ago, basically breaking temp1 and temp3, and nobody ever
complained.

The comment says that limits are cached for 60 seconds but the code
actually caches them for only 2 seconds. Align the code on the
comment, as 60 seconds makes more sense.

Subject: leds-gpio: fix possible crash on OF device unbinding

If there are leds present in the OF tree, but the GPIOs for (some) of
them are unavailable, led_data doesn't get populated with correct
devices. Then, on device unbinding, one can crash the kernel.

Workaround this by setting led->gpio to invalid value early.

Subject: crypto: gcm - fix another complete call in complete fuction

The flow of the complete function (xxx_done) in gcm.c is as follow:

void complete(struct crypto_async_request *areq, int err)
{
	struct aead_request *req = areq->data;

	if (!err) {
		err = async_next_step();
		if (err == -EINPROGRESS || err == -EBUSY)
			return;
	}

	complete_for_next_step(areq, err);
}

But *areq may be destroyed in async_next_step(), this makes
complete_for_next_step() can not work properly. To fix this, one of
following methods is used for each complete function.

- Add a __complete() for each complete(), which accept struct
  aead_request *req instead of areq, so avoid using areq after it is
  destroyed.

- Expand complete_for_next_step().

The fixing method is based on the idea of Herbert Xu.

Subject: cifs: clear server inode number flag while autodisabling

Fix the commit ec06aedd44 that intended to turn off querying for server inode
numbers when server doesn't consistently support inode numbers. Presumably
the commit didn't actually clear the CIFS_MOUNT_SERVER_INUM flag, perhaps a
typo.

Subject: at91: at91sam9g20ek modify dual slot evaluation kit

at91sam9g20ek rev. C and onwards embed two SD/MMC slots. This patch modify the
previous dual slot board definition to match the official rev. C board. It also
allows the use of at91_mci SD/MMC driver in addition to the atmel-mci one.

Some pins have been re-affected from leds or Ethernet phy IRQ to the SD/MMC
slot A. This lead to a modification of those definitions.

Subject: ARM: 5787/1: U300 COH 901 331 fixes

This will fix some small issues with the COH 901 331 RTC driver:
- Interrupt is disabled after alarm so that we don't fire
  multiple interrupts.
- We return 0 from the coh901331_alarm_irq_enable() ridding
  a compile warning.
- We alter the name in the U300 device registry to match that
  of the driver so they sucessfully resolve.

hx4700 touchscreen events were being dropped in ads7846_rx() because their
pressure values consistently exceeded the platform maximum of 512; a sample
of 256 pressure values were in the range 531 to 815.  Doubling the platform
maximum to 1024 allows hx4700 touchscreen events to pass the test.

Subject: Input: psmouse - fix breakage introduced by b7802c5c1ea

Commit b7802c5c1ea ("Input: psmouse - use boolean type") caused the
synaptics_hardware variable to be completely useless, as it is
constantly set to 'true' throughout the whole psmouse_extensions().
This was caused by the following hunk in the commit in question

	-       int synaptics_hardware = 0;
	+       bool synaptics_hardware = true;

which is wrong and causes driver to issue extra reset when falling
back to bare PS/2 protocol.

Subject: ppp: fix BUG on non-linear SKB (multilink receive)

PPP does not correctly call pskb_may_pull() on all necessary receive paths
before reading the PPP protocol, thus causing PPP to report seemingly
random 'unsupported protocols' and eventually trigger BUG_ON(skb->len <
skb->data_len) in skb_pull_rcsum() when receiving multilink protocol in
non-linear skbs.

ppp_receive_nonmp_frame() does not call pskb_may_pull() before reading the
protocol number.  For the non-mp receive path this is not a problem, as
this check is done in ppp_receive_frame().  For the mp receive path,
ppp_mp_reconstruct() usually copies the data into a new linear skb.
However, in the case where the frame is made up of a single mp fragment,
the mp header is pulled and the existing skb used.  This skb was then
passed to ppp_receive_nonmp_frame() without checking if the encapsulated
protocol header could safely be read.

The function __devexit .mdio_gpio_bus_destroy() references
a function __devinit .mdio_gpio_bus_deinit().
This is often seen when error handling in the exit function
uses functionality in the init path.
The fix is often to remove the __devinit annotation of
.mdio_gpio_bus_deinit() so it may be used outside an init section.

Subject: gro: Fix illegal merging of trailer trash

When we've merged skb's with page frags, and subsequently receive
a trailer skb (< MSS) that is not completely non-linear (this can
occur on Intel NICs if the packet size falls below the threshold),
GRO ends up producing an illegal GSO skb with a frag_list.

This is harmless unless the skb is then forwarded through an
interface that requires software GSO, whereupon the GSO code
will BUG.

This patch detects this case in GRO and avoids merging the
trailer skb.

Hi,
I was hit by a bug in linux 2.6.31 when XFS is not able to recover the
log after a crash if fs was mounted with quotas. Gory details in XFS
bugzilla: http://oss.sgi.com/bugzilla/show_bug.cgi?id=855.

It looks like wrong struct is used in buffer length check, and the following
patch should fix the problem.

xfs_dqblk_t has a size of 104+32 bytes, while xfs_disk_dquot_t is 104 bytes
long, and this is exactly what I see in system logs - "XFS: dquot too small
(104) in xlog_recover_do_dquot_trans."

Subject: xfs: copy li_lsn before dropping AIL lock

Access to log items on the AIL is generally protected by m_ail_lock;
this is particularly needed when we're getting or setting the 64-bit
li_lsn on a 32-bit platform.  This patch fixes a couple places where we
were accessing the log item after dropping the AIL lock on 32-bit
machines.

This can result in a partially-zeroed log->l_tail_lsn if
xfs_trans_ail_delete is racing with xfs_trans_ail_update, and in at
least some cases, this can leave the l_tail_lsn with a zero cycle
number, which means xlog_space_left will think the log is full (unless
CONFIG_XFS_DEBUG is set, in which case we'll trip an ASSERT), leading to
processes stuck forever in xlog_grant_log_space.

Thanks to Adrian VanderSpek for first spotting the race potential and to
Dave Chinner for debug assistance.

Subject: fcntl: Use consistent values for F_[GS]ETOWN_EX

These values were only introduced during this release cycle, so it is
still early enough to get them right.

alpha uses the same values that are in asm-generic/fcntl.h, so just
remove them.

parisc uses the values interchanged for no apparent reason, so remove
them to give us consistency across all architectures.

Fix the freqsel value computation. Use n instead of (n+1)

The formula in the TRM uses a zero-based N, hence the (n+1); however
at this point in the clock34xx.c code, N is one-based.

Current calculation does not take into account any changes to M2 divisor, and

Subject: tty_port: If we are opened non blocking we still need to raise the
 carrier

Original discussion:
http://thread.gmane.org/gmane.linux.usb.general/23217/focus=23248
or
http://marc.info/?l=linux-usb&m=125553790714133&w=2

The tty_port code inherited a bug common to various drivers it was based
upon. If the tty is opened O_NONBLOCK we do not wait for the carrier to be
raised but we must still raise our modem lines if appropriate.

(There is a second question here about whether we should do so if CLOCAL is
 set but that can wait)

Original discussion:

or
http://marc.info/?l=linux-usb&m=125553790714133&w=2

9a68e39d4a701fb3be03cae9b462408664ebd205 broke carrier handling so that a
cp210x setup which needed the carrier lines set up (non CLOCAL) which did
not make a call which set the termios bits left the lines down even if
CLOCAL was not asserted.

Fix this not by reverting but by adding the proper dtr_rts and
carrier_raised methods. This both sets the modem lines properly and also
implements the correct blocking semantics for the port as required by
POSIX.

If acm_rx_tasklet() gets called before tty_port_block_til_ready()
returns, then bulk IN urbs may not be sent. This fixes it.

I have the same problem with cdc-acm (I'm using a Samsung SGH-U900): when I
unplug it from the USB port during a PPP connection, the ppp daemon gets the
hangup correctly (and closes the device), but the struct acm corresponding to
the device disconnected is not freed. Hence reconnecting the device results in
creation of /dev/ttyACM(x+1). The same happens when the system is hibernated
during a PPP connection.

This memory leak is due to the fact that when the tty is hung up,
tty_port_close_start() returns always zero, and acm_tty_close() never reaches
the point where acm_tty_unregister() is called.

Here is a fix for this.

Subject: USB: xhci: Fix TRB physical to virtual address translation.

The trb_in_td() function in the xHCI driver is supposed to translate a
physical transfer buffer request (TRB) into a virtual pointer to the ring
segment that TRB is in.

Unfortunately, a mistake in this function may cause endless loops as the
driver searches through the linked list of ring segments over and over
again.  Fix a couple bugs that may lead to loops or bad output:

1. Bail out if we get a NULL pointer when translating the segment's
private structure and the starting DMA address of the segment chunk.  If
this happens, we've been handed a starting TRB pointer from a different
ring.

2. Make sure the function works when there's multiple segments in the
ring.  In the while loop to search through the ring segments, use the
current segment variable (cur_seg), rather than the starting segment
variable (start_seg) that is passed in.

3. Stop searching the ring if we've run through all the segments in the
ring.

Subject: USB: usbmon: fix bug in mon_buff_area_shrink

This patch (as1299b) fixes a bug in an error-handling path of usbmon's
binary interface.  The storage area for URB data is divided into
fixed-size blocks.  If an URB's data can't be copied, the area
reserved for it should be decreased to the size of the truncated
information (rounded up to a block boundary).  Rounding up the amount
to be removed and subtracting it from the reserved size is definitely
the wrong thing to do.

Also, when the data for an isochronous URB can't be copied, we can
still copy the isoc packet descriptors.  In fact the current code does
copy the descriptors, but then sets the capture length to 0 so they
remain inaccessible.  The capture length should be reduced to the
length of the descriptors, not set to 0.

Subject: workqueue: fix race condition in schedule_on_each_cpu()

Commit 65a64464349883891e21e74af16c05d6e1eeb4e9 ("HWPOISON: Allow
schedule_on_each_cpu() from keventd") which allows schedule_on_each_cpu()
to be called from keventd added a race condition.  schedule_on_each_cpu()
may race with cpu hotplug and end up executing the function twice on a
cpu.

Fix it by moving direct execution into the section protected with
get/put_online_cpus().  While at it, update code such that direct
execution is done after works have been scheduled for all other cpus and
drop unnecessary cpu != orig test from flush loop.

Subject: mm: allow memory hotplug and hibernation in the same kernel

Allow memory hotplug and hibernation in the same kernel

Memory hotplug and hibernation were exclusive in Kconfig.  This is
obviously a problem for distribution kernels who want to support both in
the same image.

After some discussions with Rafael and others the only problem is with
parallel memory hotadd or removal while a hibernation operation is in
process.  It was also working for s390 before.

This patch removes the Kconfig level exclusion, and simply makes the
memory add / remove functions grab the pm_mutex to exclude against
hibernation.

Fixes a regression - old kernels didn't exclude memory hotadd and
hibernation.

Subject: fcntl: rename F_OWNER_GID to F_OWNER_PGRP

This is for consistency with various ioctl() operations that include the
suffix "PGRP" in their names, and also for consistency with PRIO_PGRP,
used with setpriority() and getpriority().  Also, using PGRP instead of
GID avoids confusion with the common abbreviation of "group ID".

I'm fine with anything that makes it more consistent, and if PGRP is what
is the predominant abbreviation then I see no need to further confuse
matters by adding a third one.

There is a typo in the longhaul detection code so only Longhaul v1 or Longhaul v3

Tested on PCChips Giga Pro board. Frequency changes work and the Longhaul v2

issue ASAP. Issue was introduced by following commit

Subject: [CPUFREQ] Resolve time unit thinko in ondemand/conservative govs

ondemand and conservative governors are messing up time units in the
code path where NO_HZ is not enabled and ignore_nice is set. The walltime
idletime stored is in jiffies and nice time calculation is happening in
microseconds.

The problem was reported and diagnosed by Alexander here.
http://marc.info/?l=linux-kernel&m=125752550404513&w=2

The patch below fixes this thinko.

Subject: [CPUFREQ] Fix stale cpufreq_cpu_governor pointer

Dave,

Attached is an update of my patch against the cpufreq fixes branch.

Before applying the patch I compiled and booted the tree to see if the panic
was still there -- to my surprise it was not.  This is because of the conversion
of cpufreq_cpu_governor to a char[].

While the panic is kaput, the problem of stale data continues and my patch is
still valid.  It is possible to end up with the wrong governor after hotplug
events because CPUFREQ_DEFAULT_GOVERNOR is statically linked to a default,
while the cpu siblings may have had a different governor assigned by a user.

ie) the patch is still needed in order to keep the governors assigned
properly when hotplugging devices

Subject: firewire: ohci: Make cycleMatch ISO transmission work

Calling the START_ISO ioctl with a nonnegative cycle paramater has
never worked.  Last night I got around to figuring out why.  Most of
this patch is a big comment explaining why we enable an interrupt
source then don't actually do anything when we get one.  As the
comment says, we should do more, but we don't have a way to tell
userspace what happened. . .

  Date:   Thu Oct 29 08:34:00 2009 +0100

      mac80211: fix addba timer

left a problem in there, even if the timer was
never started it could be deleted and then added.

Linus pointed out that del_timer_sync() isn't
actually needed if we make the timer able to
deal with no longer being needed when it gets
queued _while_ we're in the locked section that
also deletes it. For that the timer function only
needs to check the HT_ADDBA_RECEIVED_MSK bit as
well as the HT_ADDBA_REQUESTED_MSK bit, only if
the former is clear should it do anything.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Doing the strcmp return value as

	signed char __res = *cs - *ct;

is wrong for two reasons.  The subtraction can overflow because __res
doesn't use a type big enough.  Moreover the compared bytes should be
interpreted as unsigned char as specified by POSIX.

The same problem is fixed in strncmp.

Subject: mac80211: fix resume

When mac80211 resumes, it currently first sets suspended
to false so the driver can start doing things and we can
receive frames.

However, if we actually receive frames then it can end
up starting some work which adds timers and then later
runs into a BUG_ON in the timer code because it tries
add_timer() on a pending timer.

Fix this by keeping track of the resuming process by
introducing a new variable 'resuming' which gets set to
true early on instead of setting 'suspended' to false,
and allow queueing work but not receiving frames while
resuming.

Subject: SLOW_WORK: Make slow_work_ops ->get_ref/->put_ref optional

Make the ability for the slow-work facility to take references on a work item
optional as not everyone requires this.

Even the internal slow-work stubs them out, so those can be got rid of too.

Subject: SLOW_WORK: Add support for cancellation of slow work

Add support for cancellation of queued slow work and delayed slow work items.
The cancellation functions will wait for items that are pending or undergoing
execution to be discarded by the slow work facility.

Attempting to enqueue work that is in the process of being cancelled will
result in ECANCELED.

In the 'THR' column, executing items show the thread they're occupying and
queued threads indicate which queue they're on.  'PID' shows the process ID of
a slow-work thread that's executing something.  'FL' shows the work item flags.
'MARK' indicates how long since an item was queued or began executing.  Lastly,
the 'DESC' column permits the owner of an item to give some information.

+In the 'THR' column, executing items show the thread they're occupying and
+queued threads indicate which queue they're on.  'PID' shows the process ID of
+a slow-work thread that's executing something.  'FL' shows the work item flags.
+'MARK' indicates how long since an item was queued or began executing.  Lastly,
+the 'DESC' column permits the owner of an item to give some information.

Subject: SLOW_WORK: Allow the owner of a work item to determine if it is
 queued or not

Add a function (slow_work_is_queued()) to permit the owner of a work item to
determine if the item is queued or not.

The work item is counted as being queued if it is actually on the queue, not
just if it is pending.  If it is executing and pending, then it is not on the
queue, but will rather be put back on the queue when execution finishes.

This permits a caller to quickly work out if it may be able to put another,
dependent work item on the queue behind it, or whether it will have to wait
till that is finished.

This can be used by CacheFiles to work out whether the creation a new object
can be immediately deferred when it has to wait for an old object to be
deleted, or whether a wait must take place.  If a wait is necessary, then the
slow-work thread can otherwise get blocked, preventing the deletion from
taking place.

Add a function to allow a requeueable work item to sleep till the thread
processing it is needed by the slow-work facility to perform other work.

Sometimes a work item can't progress immediately, but must wait for the
completion of another work item that's currently being processed by another
slow-work thread.

In some circumstances, the waiting item could instead - theoretically - put
itself back on the queue and yield its thread back to the slow-work facility,
thus waiting till it gets processing time again before attempting to progress.
This would allow other work items processing time on that thread.

However, this only works if there is something on the queue for it to queue
behind - otherwise it will just get a thread again immediately, and will end
up cycling between the queue and the thread, eating up valuable CPU time.

So, slow_work_sleep_till_thread_needed() is provided such that an item can put
itself on a wait queue that will wake it up when the event it is actually
interested in occurs, then call this function in lieu of calling schedule().

This function will then sleep until either the item's event occurs or another
work item appears on the queue.  If another work item is queued, but the
item's event hasn't occurred, then the work item should requeue itself and
yield the thread back to the slow-work facility by returning.

This can be used by CacheFiles for an object that is being created on one
thread to wait for an object being deleted on another thread where there is
nothing on the queue for the creation to go and wait behind.  As soon as an
item appears on the queue that could be given thread time instead, CacheFiles
can stick the creating object back on the queue and return to the slow-work
facility - assuming the object deletion didn't also complete.

 another depends is on the queue, thus allowing a dependent item to be queued
 after it.
 
+If the above shows an item on which another depends not to be queued, then the
+owner of the dependent item might need to wait.  However, to avoid locking up
+the threads unnecessarily be sleeping in them, it can make sense under some
+circumstances to return the work item to the queue, thus deferring it until
+some other items have had a chance to make use of the yielded thread.
+
+To yield a thread and defer an item, the work function should simply enqueue
+the work item again and return.  However, this doesn't work if there's nothing
+actually on the queue, as the thread just vacated will jump straight back into
+the item's work function, thus busy waiting on a CPU.
+
+Instead, the item should use the thread to wait for the dependency to go away,
+but rather than using schedule() or schedule_timeout() to sleep, it should use
+the following function:
+
+	bool requeue = slow_work_sleep_till_thread_needed(
+			struct slow_work *work,
+			signed long *_timeout);
+
+This will add a second wait and then sleep, such that it will be woken up if
+either something appears on the queue that could usefully make use of the
+thread - and behind which this item can be queued, or if the event the caller
+set up to wait for happens.  True will be returned if something else appeared
+on the queue and this work function should perhaps return, of false if
+something else woke it up.  The timeout is as for schedule_timeout().
+
+For example:
+
+	wq = bit_waitqueue(&my_flags, MY_BIT);
+	init_wait(&wait);
+	requeue = false;
+	do {
+		prepare_to_wait(wq, &wait, TASK_UNINTERRUPTIBLE);
+		if (!test_bit(MY_BIT, &my_flags))
+			break;
+		requeue = slow_work_sleep_till_thread_needed(&my_work,
+							     &timeout);
+	} while (timeout > 0 && !requeue);
+	finish_wait(wq, &wait);
+	if (!test_bit(MY_BIT, &my_flags)
+		goto do_my_thing;
+	if (requeue)
+		return; // to slow_work

From 4fbf4291aa15926cd4fdca0ffe9122e89d0459db Mon Sep 17 00:00:00 2001
From: David Howells <dhowells@redhat.com>
Date: Thu, 19 Nov 2009 18:11:04 +0000
Subject: FS-Cache: Allow the current state of all objects to be dumped

Allow the current state of all fscache objects to be dumped by doing:

	cat /proc/fs/fscache/objects

By default, all objects and all fields will be shown.  This can be restricted
by adding a suitable key to one of the caller's keyrings (such as the session
keyring):

	keyctl add user fscache:objlist "<restrictions>" @s

The <restrictions> are:

	K	Show hexdump of object key (don't show if not given)
	A	Show hexdump of object aux data (don't show if not given)

And paired restrictions:

	C	Show objects that have a cookie
	c	Show objects that don't have a cookie
	B	Show objects that are busy
	b	Show objects that aren't busy
	W	Show objects that have pending writes
	w	Show objects that don't have pending writes
	R	Show objects that have outstanding reads
	r	Show objects that don't have outstanding reads
	S	Show objects that have slow work queued
	s	Show objects that don't have slow work queued

If neither side of a restriction pair is given, then both are implied.  For
example:

	keyctl add user fscache:objlist KB @s

shows objects that are busy, and lists their object keys, but does not dump
their auxiliary data.  It also implies "CcWwRrSs", but as 'B' is given, 'b' is
not implied.

From 52bd75fdb135d6133d878ae60c6e7e3f4ebc1cfc Mon Sep 17 00:00:00 2001
From: David Howells <dhowells@redhat.com>
Date: Thu, 19 Nov 2009 18:11:08 +0000
Subject: FS-Cache: Add counters for entry/exit to/from cache operation
 functions

Count entries to and exits from cache operation table functions.  Maintain
these as a single counter that's added to or removed from as appropriate.

Subject: FS-Cache: Clear netfs pointers in cookie after detaching object, not
 before

Clear the pointers from the fscache_cookie struct to netfs private data after
clearing the pointer to the cookie from the fscache_object struct and
releasing the object lock, rather than before.

This allows the netfs private data pointers to be relied on simply by holding
the object lock, rather than having to hold the cookie lock.  This is makes
things simpler as the cookie lock has to be taken before the object lock, but
sometimes the object pointer is all that the code has.

Subject: FS-Cache: Use radix tree preload correctly in tracking of pages to be
 stored

__fscache_write_page() attempts to load the radix tree preallocation pool for
the CPU it is on before calling radix_tree_insert(), as the insertion must be
done inside a pair of spinlocks.

Use of the preallocation pool, however, is contingent on the radix tree being
initialised without __GFP_WAIT specified.  __fscache_acquire_cookie() was
passing GFP_NOFS to INIT_RADIX_TREE() - but that includes __GFP_WAIT.

The solution is to AND out __GFP_WAIT.

Additionally, the banner comment to radix_tree_preload() is altered to make
note of this prerequisite.  Possibly there should be a WARN_ON() too.

Without this fix, I have seen the following recursive deadlock caused by
radix_tree_insert() attempting to allocate memory inside the spinlocked
region, which resulted in FS-Cache being called back into to release memory -
which required the spinlock already held.

Subject: FS-Cache: Permit cache retrieval ops to be interrupted in the initial
 wait phase

Permit the operations to retrieve data from the cache or to allocate space in
the cache for future writes to be interrupted whilst they're waiting for
permission for the operation to proceed.  Typically this wait occurs whilst the
cache object is being looked up on disk in the background.

If an interruption occurs, and the operation has not yet been given the
go-ahead to run, the operation is dequeued and cancelled, and control returns
to the read operation of the netfs routine with none of the requested pages
having been read or in any way marked as known by the cache.

This means that the initial wait is done interruptibly rather than
uninterruptibly.

In addition, extra stats values are made available to show the number of ops
cancelled and the number of cache space allocations interrupted.

Subject: FS-Cache: The object-available state can't rely on the cookie to be
 available

The object-available state in the object processing state machine (as
processed by fscache_object_available()) can't rely on the cookie to be
available because the FSCACHE_COOKIE_CREATING bit may have been cleared by
fscache_obtained_object() prior to the object being put into the
FSCACHE_OBJECT_AVAILABLE state.

Clearing the FSCACHE_COOKIE_CREATING bit on a cookie permits
__fscache_relinquish_cookie() to proceed and detach the cookie from the
object.

To deal with this, we don't dereference object->cookie in
fscache_object_available() if the object has already been detached.

In addition, a couple of assertions are added into fscache_drop_object() to
make sure the object is unbound from the cookie before it gets there.

Subject: FS-Cache: Fix lock misorder in fscache_write_op()

FS-Cache has two structs internally for keeping track of the internal state of
a cached file: the fscache_cookie struct, which represents the netfs's state,
and fscache_object struct, which represents the cache's state.  Each has a
pointer that points to the other (when both are in existence), and each has a
spinlock for pointer maintenance.

Since netfs operations approach these structures from the cookie side, they get
the cookie lock first, then the object lock.  Cache operations, on the other
hand, approach from the object side, and get the object lock first.  It is not
then permitted for a cache operation to get the cookie lock whilst it is
holding the object lock lest deadlock occur; instead, it must do one of two
things:

 (1) increment the cookie usage counter, drop the object lock and then get both
     locks in order, or

 (2) simply hold the object lock as certain parts of the cookie may not be
     altered whilst the object lock is held.

It is also not permitted to follow either pointer without holding the lock at
the end you start with.  To break the pointers between the cookie and the
object, both locks must be held.

fscache_write_op(), however, violates the locking rules: It attempts to get the
cookie lock without (a) checking that the cookie pointer is a valid pointer,
and (b) holding the object lock to protect the cookie pointer whilst it follows
it.  This is so that it can access the pending page store tree without
interference from __fscache_write_page().

This is fixed by splitting the cookie lock, such that the page store tracking
tree is protected by its own lock, and checking that the cookie pointer is
non-NULL before we attempt to follow it whilst holding the object lock.

The new lock is subordinate to both the cookie lock and the object lock, and so
should be taken after those.

Don't delete pending pages from the page-store tracking tree, but rather send
them for another write as they've presumably been updated.

Subject: FS-Cache: Handle read request vs lookup, creation or other cache

FS-Cache doesn't correctly handle the netfs requesting a read from the cache
on an object that failed or was withdrawn by the cache.  A trace similar to
the following might be seen:

The object state might also be OBJECT_DYING or OBJECT_WITHDRAWING.

This should be handled by simply rejecting the new operation with ENOBUFS.
There's no need to log an error for it.  Events of this type now appear in the
stats file under Ops:rej.

Subject: FS-Cache: Handle pages pending storage that get evicted under OOM
 conditions

Handle netfs pages that the vmscan algorithm wants to evict from the pagecache
under OOM conditions, but that are waiting for write to the cache.  Under these
conditions, vmscan calls the releasepage() function of the netfs, asking if a
page can be discarded.

The problem is typified by the following trace of a stuck process:

	 [<ffffffff8100bed0>] ? child_rip+0x0/0x20

In the above backtrace, the following is happening:

 (1) A page storage operation is being executed by a slow-work thread
     (fscache_write_op()).

 (2) FS-Cache farms the operation out to the cache to perform
     (cachefiles_write_page()).

 (3) CacheFiles is then calling Ext3 to perform the actual write, using Ext3's
     standard write (do_sync_write()) under KERNEL_DS directly from the netfs
     page.

 (4) However, for Ext3 to perform the write, it must allocate some memory, in
     particular, it must allocate at least one page cache page into which it
     can copy the data from the netfs page.

 (5) Under OOM conditions, the memory allocator can't immediately come up with
     a page, so it uses vmscan to find something to discard
     (try_to_free_pages()).

 (6) vmscan finds a clean netfs page it might be able to discard (possibly the
     one it's trying to write out).

 (7) The netfs is called to throw the page away (nfs_release_page()) - but it's
     called with __GFP_WAIT, so the netfs decides to wait for the store to
     complete (__fscache_wait_on_page_write()).

 (8) This blocks a slow-work processing thread - possibly against itself.

The system ends up stuck because it can't write out any netfs pages to the
cache without allocating more memory.

To avoid this, we make FS-Cache cancel some writes that aren't in the middle of
actually being performed.  This means that some data won't make it into the
cache this time.  To support this, a new FS-Cache function is added
fscache_maybe_release_page() that replaces what the netfs releasepage()
functions used to do with respect to the cache.

The decisions fscache_maybe_release_page() makes are counted and displayed
through /proc/fs/fscache/stats on a line labelled "VmScan".  There are four
counters provided: "nos=N" - pages that weren't pending storage; "gon=N" -
pages that were pending storage when we first looked, but weren't by the time
we got the object lock; "bsy=N" - pages that we ignored as they were actively
being written when we looked; and "can=N" - pages that we cancelled the storage
of.

What I'd really like to do is alter the behaviour of the cancellation
heuristics, depending on how necessary it is to expel pages.  If there are
plenty of other pages that aren't waiting to be written to the cache that
could be ejected first, then it would be nice to hold up on immediate
cancellation of cache writes - but I don't see a way of doing that.

Subject: FS-Cache: Make sure FSCACHE_COOKIE_LOOKING_UP cleared on lookup
 failure

We must make sure that FSCACHE_COOKIE_LOOKING_UP is cleared on lookup failure
(if an object reaches the LC_DYING state), and we should clear it before
clearing FSCACHE_COOKIE_CREATING.

If this doesn't happen then fscache_wait_for_deferred_lookup() may hold
allocation and retrieval operations indefinitely until they're interrupted by
signals - which in turn pins the dying object until they go away.

Subject: FS-Cache: Start processing an object's operations on that object's
 death

Start processing an object's operations when that object moves into the DYING
state as the object cannot be destroyed until all its outstanding operations
have completed.

Furthermore, make sure that read and allocation operations handle being woken
up on a dead object.  Such events are recorded in the Allocs.abt and
Retrvls.abt statistics as viewable through /proc/fs/fscache/stats.

The code for waiting for object activation for the read and allocation
operations is also extracted into its own function as it is much the same in
all cases, differing only in the stats incremented.

Subject: FS-Cache: Actually requeue an object when requested

FS-Cache objects have an FSCACHE_OBJECT_EV_REQUEUE event that can theoretically
be raised to ask the state machine to requeue the object for further processing
before the work function returns to the slow-work facility.

However, fscache_object_work_execute() was clearing that bit before checking
the event mask to see whether the object has any pending events that require it
to be requeued immediately.

Instead, the bit should be cleared after the check and enqueue.

Subject: CacheFiles: Don't write a full page if there's only a partial page to
 cache

cachefiles_write_page() writes a full page to the backing file for the last
page of the netfs file, even if the netfs file's last page is only a partial
page.

This causes the EOF on the backing file to be extended beyond the EOF of the
netfs, and thus the backing file will be truncated by cachefiles_attr_changed()
called from cachefiles_lookup_object().

So we need to limit the write we make to the backing file on that last page
such that it doesn't push the EOF too far.

Also, if a backing file that has a partial page at the end is expanded, we
discard the partial page and refetch it on the basis that we then have a hole
in the file with invalid data, and should the power go out...  A better way to
deal with this could be to record a note that the partial page contains invalid
data until the correct data is written into it.

This isn't a problem for netfs's that discard the whole backing file if the
file size changes (such as NFS).

Mark parent directory locks as I_MUTEX_PARENT in the callers of

vfs_unlink():

Subject: CacheFiles: Better showing of debugging information in active object
 problems

Show more debugging information if cachefiles_mark_object_active() is asked to
activate an active object.

This may happen, for instance, if the netfs tries to register an object with
the same key multiple times.

The code is changed to (a) get the appropriate object lock to protect the
cookie pointer whilst we dereference it, and (b) get and display the cookie key
if available.

Subject: CacheFiles: Catch an overly long wait for an old active object

Catch an overly long wait for an old, dying active object when we want to
replace it with a new one.  The probability is that all the slow-work threads
are hogged, and the delete can't get a look in.

What we do instead is:

 (1) if there's nothing in the slow work queue, we sleep until either the dying
     object has finished dying or there is something in the slow work queue
     behind which we can queue our object.

 (2) if there is something in the slow work queue, we return ETIMEDOUT to
     fscache_lookup_object(), which then puts us back on the slow work queue,
     presumably behind the deletion that we're blocked by.  We are then
     deferred for a while until we work our way back through the queue -
     without blocking a slow-work thread unnecessarily.

A backtrace similar to the following may appear in the log without this patch:

	INFO: task kslowd004:5711 blocked for more than 120 seconds.
	"echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.

Subject: CacheFiles: Don't log lookup/create failing with ENOBUFS

Don't log the CacheFiles lookup/create object routined failing with ENOBUFS as
under high memory load or high cache load they can do this quite a lot.  This
error simply means that the requested object cannot be created on disk due to
lack of space, or due to failure of the backing filesystem to find sufficient
resources.

Subject: veth: Fix veth_get_stats()

veth_get_stats() can be called in parallel on several cpus.

It's better to not reset dev->stats as it could give wrong result on
one cpu. Use temporary variables, then store the final results.

Also, we should loop on every possible cpus, not only online cpus,
or cpu hotplug can suddenly give wrong veth stats.

Subject: Fix handling of the HP/Acer 'DMAR at zero' BIOS error for machines
 with <4GiB RAM.

Commit 86cf898e1d0fca245173980e3897580db38569a8 ("intel-iommu: Check for
'DMAR at zero' BIOS error earlier.") was supposed to work by pretending
not to detect an IOMMU if it was actually being reported by the BIOS at
physical address zero.

However, the intel_iommu_init() function is called unconditionally, as
are the corresponding functions for other IOMMU hardware.

So the patch only worked if you have RAM above the 4GiB boundary. It
caused swiotlb to be initialised when no IOMMU was detected during early
boot, and thus the later IOMMU init would refuse to run.

But if you have less RAM than that, swiotlb wouldn't get set up and the
IOMMU _would_ still end up being initialised, even though we never
claimed to detect it.

This patch also sets the dmar_disabled flag when the error is detected
during the initial detection phase -- so that the later call to
intel_iommu_init() will return without doing anything, regardless of
whether swiotlb is used or not.

Subject: vt: Fix use of "new" in a struct field

As this struct is exposed to user space and the API was added for this
release it's a bit of a pain for the C++ world and we still have time to
fix it. Rename the fields before we end up with that pain in an actual
release.

Subject: sata_fsl: Split hard and soft reset

Split sata_fsl_softreset() into hard and soft resets to make
error-handling more efficient & device and PMP detection more
reliable.

Also includes fix for PMP support, driver tested with Sil3726,
Sil4726 & Exar PMP controllers.

[AV: Also fixes resuming from deep sleep on MPC8315 CPUs]

Subject: async_tx: build-time toggling of async_{syndrome,xor}_val dma support

ioat3.2 does not support asynchronous error notifications which makes
the driver experience latencies when non-zero pq validate results are
expected.  Provide a mechanism for turning off async_xor_val and
async_syndrome_val via Kconfig.  This approach is generally useful for
any driver that specifies ASYNC_TX_DISABLE_CHANNEL_SWITCH and would like
to force the async_tx api to fall back to the synchronous path for
certain operations.

Subject: ioat3: fix pq completion versus channel deallocation race

The completion of a pq operation is notified with a null descriptor
appended to the end of the chain.  This descriptor needs to be visible
to dma clients otherwise the client is precluded from ensuring all
operations are quiesced before freeing channel resources, i.e. due to
descriptor polling it may get the completion notification ahead of the
interrupt delivered by the null descriptor.

I stumbled over two small things regarding the .index field assignment

Even though that doesn't currently cause any problem, it should still be
fixed in case the logic in the CPUFREQ core changes.

Subject: SLOW_WORK: Fix CIFS to pass THIS_MODULE to slow_work_register_user()

As of the patch:

	SLOW_WORK: Wait for outstanding work items belonging to a module to clear

	Wait for outstanding slow work items belonging to a module to clear
	when unregistering that module as a user of the facility.  This
	prevents the put_ref code of a work item from being taken away before
	it returns.

slow_work_register_user() takes a module pointer as an argument.  CIFS must now
pass THIS_MODULE as that argument, lest the following error be observed:

	fs/cifs/cifsfs.c: In function 'init_cifs':
	fs/cifs/cifsfs.c:1040: error: too few arguments to function 'slow_work_register_user'

Subject: e1000e: partial revert of 3ec2a2b8 plus FC workraround for 82577/8

Commit 3ec2a2b80f3eb53851fe4cef9e65b5d33376ef89 broke Tx/Rx when using
jumbo frames on certain parts (i.e. only PAUSE frames could be exchanged
once the high water mark was reached preventing normal packet traffic).
This patch reverts the breakage and sets appropriate high and low water
marks of the Rx FIFO for 82577/82578 which require a workaround due to a
flow control issue in hardware.

Subject: e1000e: read of PHY register may access wrong page on 82578

Remove unnecessary workaround that mistakenly does not perform a page
select operation for PHY registers 29 and 30 (assuming these are the PHY
debug port address and data registers) on 82578 which can cause reads
of the Transmit with No Carrier Sense statistics register on page 778 to be
read from an incorrect page.  Also error out if the page select operation
fails.

Subject: e1000e: remove unnecessary 82577 workaround causing link issues

A workaround for pre-release versions of 82577 is causing link issues on
some switches.  The workaround is no longer needed on production parts so
remove it.

Subject: e1000e: do not initiate autonegotiation during OEM configuration

When configuring the OEM bits in the PHY on 82577/82578, do not restart
autonegotiation if the firmware is blocking it (e.g. when an IDE-R session
is active) because the link must not go down.

Summary of Changes:

	-Fix to receive multicast packets by setting the corresponding hardware
	 bit during initialization.
	-Fix to re-enable the interface [by interface up command(ifup)] while the
	 interface is down.
	-Fix to be able to down the interface by passing the last parameter
	 correctly to request_irq().
	-Remove to read 4 extra bytes from the receiving queue after reading a
	 packet, even though it does not cause a predictable issue now.
	-Remove occurrences of transmission done interrupt in order to tx
	 throughput enhancement.
	-Enable IP checksum for packet receiving by setting the corresponding
	 hardware bit during initialization.
	-Relocate ks_enable_int()/ks_disable_int() in order not to declare those
	 functions at the beginning of the file.
	-Rename ks_enable()/_disable() to ks_enable_qmu()/ks_disable_qmu() in
	 order to give more meaningful names and relocate them not declaire
	 those functions at the beginning of the file.

Subject: firewire: ohci: pass correct iso xmit timestamps to core

Here is the final set of patches I used to get ffado to work with the
new firewire stack.  With these patches, I was able to start ardour
and record from and playback to my PreSonus Inspire1394 from a
(mostly) Fedora 12 system.

Signed-off-by: Jay Fenlason <fenlason@redhat.com>

Until now, firewire-ohci exposed only the transmit cycle of the last
transmitted packet at each isochronous transmit complete event.  This
made it impossible for FFADO (FireWire audio drivers in userspace) to
synchronize audio-out streams.  The fix is to store the timestamp of
each packet in the iso xmit event.  As a bonus, the transfer status is
stored too.

Subject: netxen : fix BOND_MODE_TLB/ALB mode.

o Along with netdev->perm_addr, mac address will be
  maintained in device private structure.

o Device limitation: We need to set mac address when ever
  interface comes up.

In ALB/TAL mode, bonding driver calls set_mac for all slave with bond mac address.
But bonding driver set netdev->dev_addr field to its original value,
after enslaving interfaces.

When ever active slave changes, it swap dev_addr of inactive slave with active.
Yet it doesn't notify driver about change in netdev->dev_addr.

As netxen driver need to set mac addr when ever interface comes up,
it can't rely on netdev->dev_addr field. Specially in case of bonding mode ALB/TLB.

Subject: ASoC: Fix suspend with active audio streams

When we get a stream suspend event force the power down since otherwise
the stream would remain marked as active.  In future we'll probably want
to make this stream-specific and add an interface to make the power down
of other widgets optional in order to support leaving bypass paths
active while suspending the processor.

Subject: ARM: 5793/1: ARM: Check put_user fail in do_signal when enable
 OABI_COMPAT

Using OABI, the call to put_user in do_signal can fail causing the
calling app to hang.

The solution is to check if put_user fails and force the app to
seg fault in that case.

Tested with multiple sleeping apps/threads (using the nanosleep syscall)
and suspend/resume.

Subject: pktgen: Fix device name compares

Commit e6fce5b916cd7f7f7 (pktgen: multiqueue etc.) tried to relax
the pktgen restriction of one device per kernel thread, adding a '@'
tag to device names.

Problem is we dont perform check on full pktgen device name.
This allows adding many time same 'device' to pktgen thread

 pgset "add_device eth0@0"

one session later :

 pgset "add_device eth0@0"

(This doesnt find previous device)

This consumes ~1.5 MBytes of vmalloc memory per round and also triggers
this warning :

Solution to this problem is to use a odevname field (includes @ tag and suffix),
instead of using netdevice name.

Subject: hso: fix soft-lockup
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fix soft-lockup in hso.c which is triggered on SMP machine when
modem is removed while file descriptor(s) under /dev are still open:

  old version called kref_put() too early which resulted in destroying
  hso_serial and hso_device objects which were still used later on.

Subject: sparc64: Fix definition of VMEMMAP_SIZE.

This was the cause of various boot failures on V480, V880, etc.
systems.

Kernel image memory was being overwritten because the vmemmap[]
array was being sized to small.  So if you had physical memory
addresses past a certain point, the early bootup would spam
all over variables in the kernel data section.

The vmemmap mappings map page structs, not page struct pointers.
And that was the key thinko in the macro definition.

This was fixable thanks to the help, reports, and tireless patience
of Hermann Lauer.

Subject: drm/radeon/kms: resume AGP by calling init.

AGP resume was broken since we moved to the new init path,
because we never re-enabled AGP on these systems at resume time.

This patch just calls the AGP resume call which just does the reinit
at resume time like the old path did.

Since AGP is pretty much gpu independant I did it outside
the gpu specific code.

Subject: drm/radeon/kms: fix handling of d1/d2 vga

An rv515 laptop I got wouldn't startup with a montior plugged in,
found the proper bug hopefully with us not turning off D2VGA
here when we should.

Subject: drm/radeon/kms: read back register before writing in IIO.

This fixes RH bugzilla #527874.

On resume the atom posting wasn't working, however vbe posting was
going fine, after 2 weeks over irc, and 8 hrs with the hardware,
I tracked it down to the memory device table and it access the MC
registers via IIO, it appears the rv515 atom iio table might not
be fully functional, so adding a readback before doing a write
either provides enough delay to make things resume correctly.

Thanks to Peng Huang at Red Hat for coming to Brisbane.

Subject: drm: mm always protect change to unused_nodes with unused_lock
 spinlock

unused_nodes modification needs to be protected by unused_lock spinlock.
Here is an example of an usage where there is no such protection without
this patch.

  Process 1: 1-drm_mm_pre_get(this function modify unused_nodes list)
             2-spin_lock(spinlock protecting mm struct)
             3-drm_mm_put_block(this function might modify unused_nodes
               list but doesn't protect modification with unused_lock)
             4-spin_unlock(spinlock protecting mm struct)
  Process2:  1-drm_mm_pre_get(this function modify unused_nodes list)
At this point Process1 & Process2 might both be doing modification to
unused_nodes list. This patch add unused_lock protection into
drm_mm_put_block to avoid such issue.

On broken EDID we were reporting vga connector to be disconnected
even if ddc probe did found a monitor. This patch report that the
connector is connected on such case. This allow drm to add a fail
safe mode (800x600 at the time of this patch) thus user can boot
and later add a mode which match its monitor capabilities.

Subject: drm: make sure page protections are updated after changing vm_flags

Some architectures compute ->vm_page_prot depending on ->vm_flags, so we
need to update the protections after adjusting the flags.

AFAIK this only affects running X under Xen; without this patch you get
lots of coloured blobs on the screen, or maybe a complete lockup.  Or
anything really.

But that still depends on lots of out-of-tree stuff, so I don't think
there are any consequences for anyone else.  But it is wrong in principle.

Subject: drm/fb: fix FBIOGET/PUT_VSCREENINFO pixel clock handling

When the framebuffer driver does not publish detailed timing information
for the current video mode, the correct value for the pixclock field is
zero, not -1.

Since pixclock is actually unsigned, the value -1 would be interpreted
as 4294967295 picoseconds (i.e., about 4 milliseconds) by
register_framebuffer() and userspace programs.

This patch allows X.org's fbdev driver to work.

Subject: [CPUFREQ] Enable ACPI PDC handshake for VIA/Centaur CPUs

In commit 0de51088e6a82bc8413d3ca9e28bbca2788b5b53, we introduced the
use of acpi-cpufreq on VIA/Centaur CPU's by removing a vendor check for
VENDOR_INTEL.  However, as it turns out, at least the Nano CPU's also
need the PDC (processor driver capabilities) handshake in order to
activate the methods required for acpi-cpufreq.

Since arch_acpi_processor_init_pdc() contains another vendor check for
Intel, the PDC is not initialized on VIA CPU's.  The resulting behavior
of a current mainline kernel on such systems is:  acpi-cpufreq
loads and it indicates CPU frequency changes.  However, the CPU stays at
a single frequency

This trivial patch ensures that init_intel_pdc() is called on Intel and
VIA/Centaur CPU's alike.

Subject: serial: suncore: Fix RSC/LOM handling in sunserial_console_termios().

RSC and LOM devices have fixed speed settings.

We already had some code to match and handle "rsc" named devices on
E250 systems, but we also have to handle 'rsc-console', 'rsc-control',
and 'lom-console'.

Also, in order to get this right regardless of what 'output-device'
happens to be, explicitly pass the UART device node pointer to this
routine.

Subject: [CIFS] fix oops in cifs_lookup during net boot

Fixes bugzilla.kernel.org bug number 14641

Lookup called during network boot (network root filesystem
for diskless workstation) has case where nd is null in
lookup.  This patch fixes that in cifs_lookup.

(Shirish noted that 2.6.30 and 2.6.31 stable need the same check)

Subject: [CIFS] Duplicate data on appending to some Samba servers

SMB writes are sent with a starting offset and length. When the server
supports the newer SMB trans2 posix open (rather than using the SMB
NTCreateX) a file can be opened with SMB_O_APPEND flag, and for that
case Samba server assumes that the offset sent in SMBWriteX is unneeded
since the write should go to the end of the file - which can cause
problems if the write was cached (since the beginning part of a
page could be written twice by the client mm).  Jeff suggested that
masking the flag on posix open on the client is easiest for the time
being. Note that recent Samba server also had an unrelated problem with
SMB NTCreateX and append (see samba bugzilla bug number 6898) which
should not affect current Linux clients (unless cifs Unix Extensions
are disabled).

The cifs client did not send the O_APPEND flag on posix open
before 2.6.29 so the fix is unneeded on early kernels.

In the future, for the non-cached case (O_DIRECT, and forcedirectio mounts)
it would be possible and useful to send O_APPEND on posix open (for Windows
case: FILE_APPEND_DATA but not FILE_WRITE_DATA on SMB NTCreateX) but for
cached writes although the vfs sets the offset to end of file it
may fragment a write across pages - so we can't send O_APPEND on
open (could result in sending part of a page twice).

Subject: ACPICA: Silence the warning about _BIF returning the buffer

_BIF was returning buffer instead of a string since day 1 of ACPI.
Adding a warning for that is noble, but people don't like
when someone cries wolf in a production system.

Subject: thinkpad-acpi: fix detection of old ThinkPads

There is a problem in the quirk tables used by tpacpi_is_fw_known() and
tpacpi_check_outdated_fw(), which causes outdated BIOSes that are lacking
the EC firmware ID DMI field to never match.

This breaks module loading on, e.g.  a T23 with outdated BIOS, and the
module will refuse to load unless the "force_load=1" parameter is given.

Fix the quirk tables so that they can also match the outdated BIOSes,
which in turn will both fix the module loading, and also warn the user
that he is using outdated firmware and should upgrade.

This fixes a serious regression, introduced by commit
e675abafcc0df38125e6e94a9ba91c92fe774f52, "thinkpad-acpi: be more strict
when detecting a ThinkPad".

Subject: Blackfin: fix suspend/resume failure with some on-chip ROMs

Some Blackfin on-chip ROMs utilize some MDMA channels during the suspend
and resume process, but don't clean up after themselves.  So manually
clear all DMA channels when resuming since no DMA could have been running
at this point in time.  Now Linux should be able to work regardless of any
laziness on the part of the on-chip ROM or boot loader.

For CRT hotplug detect status, we have four test results as blue
channel only, green channel only, both blue and green channel, and
no channel attached. Origin code only marks both blue and green channel
case as connected, but ignore other possible connected states. This one
trys to detect CRT by checking no channel attached case instead.

The revealing nature of the panic is the NULL function pointer

Subject: ide: fix ioctl to pass requested transfer mode to ide_find_dma_mode
 instead of UDMA6

Currently, ide_cmd_ioctl when invoked for setting DMA transfer mode calls
ide_find_dma_mode with requested mode as XFER_UDMA_6. This prevents setting DMA
mode to any other value than the default (maximum) supported by the device (or
UDMA6, if supported) irrespective of the actual requested transfer mode and
returns error.

For example, setting mode to UDMA2 using hdparm, where UDMA4 is the default
transfer mode gives following error:
	# ./hdparm -d1 -Xudma2  /dev/hda
	 /dev/hda:hda: UDMA/66 mode selected
	 setting using_dma to 1 (on)
	 hda: UDMA/66 mode selected
	 setting xfermode to 66 (UltraDMA mode2)
	 HDIO_DRIVE_CMD(setxfermode) failed: Invalid argument
	 using_dma     =  1 (on)

This patch fixes the issue.

Subject: Input: keyboard - fix braille keyboard keysym generation

Keysyms stored in key_map[] are not simply K() values, but U(K()) values,
as can be seen in the KDSKBENT ioctl handler.  The kernel-generated
braille keysyms thus need a U() call too.

Subject: i2c: Fix userspace_device list corruption

Fix userspace_device list corruption. The corruption was caused by
clients not being removed when adapters with such clients were
themselves removed. Something like the following would trigger it
(assuming i2c-stub gets adapter number 3):

# modprobe i2c-stub chip_addr=0x50
# echo 24c08 0x50 > /sys/bus/i2c/devices/i2c-3/new_device
# rmmod i2c-stub
# modprobe i2c-stub chip_addr=0x50
# echo 24c08 0x50 > /sys/bus/i2c/devices/i2c-3/new_device

For the records, the stack trace in the kernel logs look like this:

Subject: at24: Use timeout also for read

Writes may take some time on EEPROMs, so for consecutive writes, we already
have a loop waiting for the EEPROM to become ready. Use such a loop for reads,
too, in case somebody wants to immediately read after a write. Detailed bug
report and test case can be found here:

Subject: [SCSI] fix async scan add/remove race resulting in an oops

Async scanning introduced a very wide window where the SCSI device is
up and running but has not yet been added to sysfs.  We delay the
adding until all scans have completed to retain the same ordering as
sync scanning.

This delay in visibility causes an oops if a device is removed before
we make it visible because the SCSI removal routines have an inbuilt
assumption that if a device is in SDEV_RUNNING state, it must be
visible (which is not necessarily true in the async scanning case).

Fix this by introducing an additional is_visible flag which we can use
to condition the tear down so we do the right thing for running but
not yet made visible.

Subject: [SCSI] fix crash when disconnecting usb storage

__scsi_remove_device() in scsi_forget_host() is executed out of scan_mutex
and races with scsi_destroy_sdev() <- scsi_sysfs_add_devices() <-
scsi_finish_async_scan().  The result is use after free and/or double
free, oops.

The fix is simple, move scsi_forget_host() under scan_mutex.

scsi_forget_host() is just sequence of __scsi_remove_device().  All
another calls of __scsi_remove_device() are made under scan_mutex.  So
that it is safe.

Subject: fuse: reject O_DIRECT flag also in fuse_create

The comment in fuse_open about O_DIRECT:

  "VFS checks this, but only _after_ ->open()"

also holds for fuse_create, however, the same kind of check was missing there.

As an impact of this bug, open(newfile, O_RDWR|O_CREAT|O_DIRECT) fails, but a
stub newfile will remain if the fuse server handled the implied FUSE_CREATE
request appropriately.

Other impact: in the above situation ima_file_free() will complain to open/free
imbalance if CONFIG_IMA is set.

Subject: sctp: on T3_RTX retransmit all the in-flight chunks

When retransmitting due to T3 timeout, retransmit all the
in-flight chunks for the corresponding  transport/path, including
chunks sent less then 1 rto ago.
This is the correct behaviour according to rfc4960 section 6.3.3
E3 and
"Note: Any DATA chunks that were sent to the address for which the
 T3-rtx timer expired but did not fit in one MTU (rule E3 above)
 should be marked for retransmission and sent as soon as cwnd
 allows (normally, when a SACK arrives). ".

This fixes problems when more then one path is present and the T3
retransmission of the first chunk that timeouts stops the T3 timer
for the initial active path, leaving all the other in-flight
chunks waiting forever or until a new chunk is transmitted on the
same path and timeouts (and this will happen only if the cwnd
allows sending new chunks, but since cwnd was dropped to MTU by
the timeout => it will wait until the first heartbeat).

Example: 10 packets in flight, sent at 0.1 s intervals on the
primary path. The primary path is down and the first packet
timeouts. The first packet is retransmitted on another path, the
T3 timer for the primary path is stopped and cwnd is set to MTU.
All the other 9 in-flight packets will not be retransmitted
(unless more new packets are sent on the primary path which depend
on cwnd allowing it, and even in this case the 9 packets will be
retransmitted only after a new packet timeouts which even in the
best case would be more then RTO).

This commit reverts d0ce92910bc04e107b2f3f2048f07e94f570035d and
also removes the now unused transport->last_rto, introduced in
 b6157d8e03e1e780660a328f7183bcbfa4a93a19.

p.s  The problem is not only when multiple paths are there.  It
can happen in a single homed environment.  If the application
stops sending data, it possible to have a hung association.

Subject: PM: fix irq enable/disable in runtime PM code

This patch (as1305) fixes a bug in the irq-enable settings and removes
some related overhead in the runtime PM code.

	In __pm_runtime_resume(), within the scope of the original
	spin_lock_irq(), we know that irqs are disabled.  There's no
	reason to go through a pair of enable/disable cycles when
	acquiring and releasing the parent's lock.

	In __pm_runtime_set_status(), irqs are already disabled when
	the parent's lock is acquired, and they must remain disabled
	when it is released.

 ip_fragment.c, NULL ptr OOPS

ipv4 ip_frag_reasm(), fully replace 'dev_net(dev)' with 'net', defined
previously patched into 2.6.29.

Between 2.6.28.10 and 2.6.29, net/ipv4/ip_fragment.c was patched,
changing from dev_net(dev) to container_of(...).  Unfortunately the goto
section (out_fail) on oversized packets inside ip_frag_reasm() didn't
get touched up as well.  Oversized IP packets cause a NULL pointer
dereference and immediate hang.

I discovered this running openvasd and my previous email on this is
titled:  NULL pointer dereference at 2.6.32-rc8:net/ipv4/ip_fragment.c:566

Subject: r8169: restore mac addr in rtl8169_remove_one and rtl_shutdown

The newer chipsets (all PCI-E) are known that they need full power cycle
(AC or battery removal) to reset MAC address to a  hardwired one. Previous
patch to address this problem loads the original MAC address from EEPROM.
But it brought other problem for which it is necessary to introduce a new
module parameter.
However, it might suffice to restore the initial MAC address before
shutdown/reboot/kexec and when removing the module.

Subject: NET: smc91x: Fix irq flags

smc91x.h defines SMC_IRQ_FLAGS to be -1 when it wants the interrupt
flags to be taken from the resource structure.  However, d280ead
changed this to checking for non-zero resource flags.

Unfortunately, this means that on some platforms, we end up passing
'-1' to request_irq rather than the desired result.  Combine the two
conditions into one so that the IRQ flags are taken from the resource
if either SMC_IRQ_FLAGS is -1 or the resource flags specify an
interrupt trigger.

This restores network on at least the Versatile platform.

So logging a message about it is wrong and in fact harmful.

Subject: parisc: fix unwind with recent gcc versions

kernel unwinding is broken with gcc >= 4.x.  Part of the problem is that
binutils seems very sensitive to where the unwind information is stored.

    mac80211: RX aggregation: clean up stop session

The problem is that the BUG_ON moved before the various
checks, and as such can be triggered.

As the comment indicates, the BUG_ON can be removed since
the ampdu_action callback must already exist when the
state is OPERATIONAL.

A similar code path leads to a WARN_ON in
ieee80211_stop_tx_ba_session, which can also be removed.

    mac80211: RX aggregation: clean up stop session

and other parts were already present in the original

  commit d92684e66091c0f0101819619b315b4bb8b5bcc5
  Author: Ron Rindjunsky <ron.rindjunsky@intel.com>
  Date:   Mon Jan 28 14:07:22 2008 +0200

      mac80211: A-MPDU Tx add delBA from recipient support

The first problem is that I moved a BUG_ON before various
checks -- thereby making it possible to hit. As the comment
indicates, the BUG_ON can be removed since the ampdu_action
callback must already exist when the state is != IDLE.

The second problem isn't easily exploitable but there's a
race condition due to unconditionally setting the state to
OPERATIONAL when a delBA frame is received, even when no
aggregation session was ever initiated. All the drivers
accept stopping the session even then, but that opens a
race window where crashes could happen before the driver
accepts it. Right now, a WARN_ON may happen with non-HT
drivers, while the race opens only for HT drivers.

For this case, there are two things necessary to fix it:
 1) don't process spurious delBA frames, and be more careful
    about the session state; don't drop the lock

 2) HT drivers need to be prepared to handle a session stop
    even before the session was really started -- this is
    true for all drivers (that support aggregation) but
    iwlwifi which can be fixed easily. The other HT drivers
    (ath9k and ar9170) are behaving properly already.

From 199bc9ff5ca5e4b3bcaff8927b2983c65f34c263 Mon Sep 17 00:00:00 2001

Subject: jffs2: Fix memory corruption in jffs2_read_inode_range()

In 2.6.23 kernel, commit a32ea1e1f925399e0d81ca3f7394a44a6dafa12c
("Fix read/truncate race") fixed a race in the generic code, and as a
side effect, now do_generic_file_read() can ask us to readpage() past
the i_size. This seems to be correctly handled by the block routines
(e.g. block_read_full_page() fills the page with zeroes in case if
somebody is trying to read past the last inode's block).

JFFS2 doesn't handle this; it assumes that it won't be asked to read
pages which don't exist -- and thus that there will be at least _one_
valid 'frag' on the page it's being asked to read. It will fill any
holes with the following memset:

  memset(buf, 0, min(end, frag->ofs + frag->size) - offset);

When the 'closest smaller match' returned by jffs2_lookup_node_frag() is
actually on a previous page and ends before 'offset', that results in:

  memset(buf, 0, <huge unsigned negative>);

Hopefully, in most cases the corruption is fatal, and quickly causing
random oopses, like this:

  root@10.0.0.4:~/ltp-fs-20090531# ./testcases/kernel/fs/ftest/ftest01

This patch fixes the issue, plus fixes all LTP tests on NAND/UBI with
JFFS2 filesystem that were failing since 2.6.23 (seems like the bug
above also broke the truncation).

Subject: powerpc: Fix DEBUG_HIGHMEM build break from d4515646699

Code was added to mm/higmem.c that depends on several
kmap types that powerpc does not support.  We add dummy
invalid definitions for KM_NMI, KM_NM_PTE, and KM_IRQ_PTE.

According to list discussion, this fix should not be needed
anymore starting with 2.6.33.  The code is commented to this
effect so hopefully we will remember to remove this.
