Pull the MCA deletion branch from Paul Gortmaker:
"It was good that we could support MCA machines back in the day, but
realistically, nobody is using them anymore. They were mostly limited
to 386-sx 16MHz CPU and some 486 class machines and never more than
64MB of RAM. Even the enthusiast hobbyist community seems to have
dried up close to ten years ago, based on what you can find searching
various websites dedicated to the relatively short lived hardware.
So lets remove the support relating to CONFIG_MCA. There is no point
carrying this forward, wasting cycles doing routine maintenance on it;
wasting allyesconfig build time on validating it, wasting I/O on git
grep'ping over it, and so on."
Let's see if anybody screams. It generally has compiled, and James
Bottomley pointed out that there was a MCA extension from NCR that
allowed for up to 4GB of memory and PPro-class machines. So in *theory*
there may be users out there.
But even James (technically listed as a maintainer) doesn't actually
have a system, and while Alan Cox claims to have a machine in his cellar
that he offered to anybody who wants to take it off his hands, he didn't
argue for keeping MCA support either.
So we could bring it back. But somebody had better speak up and talk
about how they have actually been using said MCA hardware with modern
kernels for us to do that. And David already took the patch to delete
all the networking driver code (commit a5e371f61ad3: "drivers/net:
delete all code/drivers depending on CONFIG_MCA").
* 'delete-mca' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux:
MCA: delete all remaining traces of microchannel bus support.
scsi: delete the MCA specific drivers and driver code
serial: delete the MCA specific 8250 support.
arm: remove ability to select CONFIG_MCA

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai:
"This is the first big chunk for 3.5 merges of sound stuff.
There are a few big changes in different areas. First off, the
streaming logic of USB-audio endpoints has been largely rewritten for
the better support of "implicit feedback". If anything about USB got
broken, this change has to be checked.
For HD-audio, the resume procedure was changed; instead of delaying
the resume of the hardware until the first use, now waking up
immediately at resume. This is for buggy BIOS.
For ASoC, dynamic PCM support and the improved support for digital
links between off-SoC devices are major framework changes.
Some highlights are below:
* HD-audio
- Avoid accesses of invalid pin-control bits that may stall the codec
- V-ref setup cleanups
- Fix the races in power-saving code
- Fix the races in codec cache hashes and connection lists
- Split some common codes for BIOS auto-parser to hda_auto_parser.c
- Changed the PM resume code to wake up immediately for buggy BIOS
- Creative SoundCore3D support
- Add Conexant CX20751/2/3/4 codec support
* ASoC
- Dynamic PCM support, allowing support for SoCs with internal
routing through components with tight sequencing and formatting
constraints within their internal paths or where there are multiple
components connected with CPU managed DMA controllers inside the
SoC.
- Greatly improved support for direct digital links between off-SoC
devices, providing a much simpler way of connecting things like
digital basebands to CODECs.
- Much more fine grained and robust locking, cleaning up some of the
confusion that crept in with multi-component.
- CPU support for nVidia Tegra 30 I2S and audio hub controllers and
ST-Ericsson MSP I2S controolers
- New CODEC drivers for Cirrus CS42L52, LAPIS Semiconductor ML26124,
Texas Instruments LM49453.
- Some regmap changes needed by the Tegra I2S driver.
- mc13783 audio support.
* Misc
- Rewrite with module_pci_driver()
- Xonar DGX support for snd-oxygen
- Improvement of packet handling in snd-firewire driver
- New USB-endpoint streaming logic
- Enhanced M-audio FTU quirks and relevant cleanups
- Increment the support of OSS devices to 256
- snd-aloop accuracy improvement
There are a few more pending changes for 3.5, but they will be sent
slightly later as partly depending on the changes of DRM."
Fix up conflicts in regmap (due to duplicate patches, with some further
updates then having already come in from the regmap tree). Also some
fairly trivial context conflicts in the imx and mcx soc drivers.

Pull powerpc updates from Benjamin Herrenschmidt:
"Here are the powerpc goodies for 3.5. Main highlights are:
- Support for the NX crypto engine in Power7+
- A bunch of Anton goodness, including some micro optimization of our
syscall entry on Power7
- I converted a pile of our thermal control drivers to the new i2c
APIs (essentially turning the old therm_pm72 into a proper set of
windfarm drivers). That's one more step toward removing the
deprecated i2c APIs, there's still a few drivers to fix, but we are
getting close
- kexec/kdump support for 47x embedded cores
The big missing thing here is no updates from Freescale. Not sure
what's up here, but with Kumar not working for them anymore things are
a bit in a state of flux in that area."

we start a infinite loop when user gives ./watchdog-test, and when user
ctrl + c's the program, we just exit immeadiately with out closing the
filedescriptor of the watchdog device. a signal handler is used to
do the job of closing the filedescriptor and exiting the program.

Pull scheduler changes from Ingo Molnar:
"The biggest change is the cleanup/simplification of the load-balancer:
instead of the current practice of architectures twiddling scheduler
internal data structures and providing the scheduler domains in
colorfully inconsistent ways, we now have generic scheduler code in
kernel/sched/core.c:sched_init_numa() that looks at the architecture's
node_distance() parameters and (while not fully trusting it) deducts a
NUMA topology from it.
This inevitably changes balancing behavior - hopefully for the better.
There are various smaller optimizations, cleanups and fixlets as well"

Pull staging tree changes from Greg Kroah-Hartman:
"Here is the big staging tree pull request for the 3.5-rc1 merge
window.
Loads of changes here, and we just narrowly added more lines than we
added:
622 files changed, 28356 insertions(+), 26059 deletions(-)
But, good news is that there is a number of subsystems that moved out
of the staging tree, to their respective "real" portions of the
kernel.
Code that moved out was:
- iio core code
- mei driver
- vme core and bridge drivers
There was one broken network driver that moved into staging as a step
before it is removed from the tree (pc300), and there was a few new
drivers added to the tree:
- new iio drivers
- gdm72xx wimax USB driver
- ipack subsystem and 2 drivers

Pull arm-soc board specific changes from Olof Johansson:
"While we generally attempt to get rid of board specific files and
replace them with device tree based descriptions, a lot of platforms
have not come that far:
In shmobile, we add two new board files because their recently started
effort to add DT support has not proceeded enough to use it for all of
the important hardware.
In Kirkwood, we are adding support for new boards with a combination
of DT and board file contents in multiple cases.
pxa/mmp and imx are extending support for existing board files but not
adding new ones."

Pull arm soc-specific pinctrl changes from Olof Johansson:
"With this, five platforms are moving to the relatively new pinctrl
subsystem for their pin management, replacing the older soc specific
in-kernel interfaces with common code.
There is quite a bit of net addition of code for each platform being
added to the pinctrl subsystem. But the payback comes later when
adding new boards can be done by only providing new device trees
instead."

Pull device tree conversions for arm-soc, part 1, from Olof Johansson:
"The spear3xx, lpc32xx, shmobile and mmp platforms are joining the game
of booting using device trees, which is a great step forward for them.
at91 and spear have pretty much completed this process with a huge
amount of work being put into at91. The other platforms are
continuing the process.

Pull first batch of arm-soc cleanups from Olof Johansson:
"These cleanups are basically all over the place. The idea is to
collect changes with minimal impact but large number of changes so we
can avoid them from distracting in the diffstat in the other series.
A significant number of lines get removed here, in particular because
the ixp2000 and ixp23xx platforms get removed. These have never been
extremely popular and have fallen into disuse over time with no active
maintainer taking care of them. The u5500 soc never made it into a
product, so we are removing it from the ux500 platform.
Many good cleanups also went into the at91 and omap platforms, as has
been the case for a number of releases."

"This is the v3.5 RCU tree from Paul E. McKenney:
1) A set of improvements and fixes to the RCU_FAST_NO_HZ feature (with
more on the way for 3.6). Posted to LKML:
https://lkml.org/lkml/2012/4/23/324 (commits 1-3 and 5),
https://lkml.org/lkml/2012/4/16/611 (commit 4),

https://lkml.org/lkml/2012/5/4/410 (commit 7, combined with
the other commits for the convenience of the tester).
2) Changes to make rcu_barrier() avoid disrupting execution of CPUs
that have no RCU callbacks. Posted to LKML:
https://lkml.org/lkml/2012/4/23/322.
3) A couple of commits that improve the efficiency of the interaction
between preemptible RCU and the scheduler, these two being all that
survived an abortive attempt to allow preemptible RCU's
__rcu_read_lock() to be inlined. The full set was posted to LKML at
https://lkml.org/lkml/2012/4/14/143, and the first and third patches
of that set remain.
4) Lai Jiangshan's algorithmic implementation of SRCU, which includes
call_srcu() and srcu_barrier(). A major feature of this new
implementation is that synchronize_srcu() no longer disturbs the
execution of other CPUs. This work is based on earlier
implementations by Peter Zijlstra and Paul E. McKenney. Posted to
LKML: https://lkml.org/lkml/2012/2/22/82.

Pull regulator updates from Mark Brown:
"The major thing here is the addition of some helpers to factor code

just need data to describe them in the drivers.
- Split out voltage mapping and voltage setting, allowing many more

"This is the bulk of the core ARM updates for this merge window.
Included in here is a different way to handle the VIVT cache flushing
on context switch, which should allow scheduler folk to remove a
special case in their core code.
We have architectured timer support here, which is a set of timers
specified by the ARM architecture for future SoCs. So we should see
less variability in timer design going forward.
The last big thing here is my cleanup to the way we handle PCI across
ARM, fixing some oddities in some platforms which hadn't realised
there was a way to deal with their private data already built in to
our PCI backend.
I've also removed support for the ARMv3 architecture; it hasn't worked

Pull sparc updates from David Miller:
1) Kill off support for sun4c and Cypress sun4m chips.
And as a result we were able to also kill off that ugly btfixup thing
that required multi-stage links of the final vmlinux image in the
Kbuild system. This should make the kbuild maintainers really happy.
Thanks a lot to Sam Ravnborg for his tireless efforts to get this
going.
2) Convert sparc64 to nobootmem. I suspect now with sparc32 being a lot
cleaner, it should be able to fall in line and modernize in this area
too.
3) Make sparc32 use generic clockevents, from Tkhai Kirill.
[ I fixed up the BPF rules, and tried to clean up the build rules too.
But I don't have - or want - a sparc cross-build environment, so the
BPF rule bug and the related build cleanup was all done with just a
bare "make -n" pseudo-test. - Linus ]

isci update for 3.5
1/ Rework remote-node-context (RNC) handling for proper management of
the silicon state machine in error handling and hot-plug conditions.
Further details below, suffice to say if the RNC is mismanaged the
silicon state machines may lock up.
2/ Refactor the initialization code to be reused for suspend/resume support
3/ Miscellaneous bug fixes to address discovery issues and hardware
compatibility.
RNC rework details from Jeff Skirvin:
In the controller, devices as they appear on a SAS domain (or
direct-attached SATA devices) are represented by memory structures known
as "Remote Node Contexts" (RNCs). These structures are transferred from
main memory to the controller using a set of register commands; these
commands include setting up the context ("posting"), removing the
context ("invalidating"), and commands to control the scheduling of
commands and connections to that remote device ("suspensions" and
"resumptions"). There is a similar path to control RNC scheduling from
the protocol engine, which interprets the results of command and data
transmission and reception.
In general, the controller chooses among non-suspended RNCs to find one
that has work requiring scheduling the transmission of command and data
frames to a target. Likewise, when a target tries to return data back
to the initiator, the state of the RNC is used by the controller to
determine how to treat the incoming request. As an example, if the RNC
is in the state "TX/RX Suspended", incoming SSP connection requests from
the target will be rejected by the controller hardware. When an RNC is
"TX Suspended", it will not be selected by the controller hardware to
start outgoing command or data operations (with certain priority-based
exceptions).
As mentioned above, there are two sources for management of the RNC
states: commands from driver software, and the result of transmission
and reception conditions of commands and data signaled by the controller
hardware. As an example of the latter, if an outgoing SSP command ends
with a OPEN_REJECT(BAD_DESTINATION) status, the RNC state will
transition to the "TX Suspended" state, and this is signaled by the
controller hardware in the status to the completion of the pending
command as well as signaled in a controller hardware event. Examples of
the former are included in the patch changelogs.
Driver software is required to suspend the RNC in a "TX/RX Suspended"
condition before any outstanding commands can be terminated. Failure to
guarantee this can lead to a complete hardware hang condition. Earlier
versions of the driver software did not guarantee that an RNC was
correctly managed before I/O termination, and so operated in an unsafe
way.
Further, the driver performed unnecessary contortions to preserve the
remote device command state and so was more complicated than it needed
to be. A simplifying driver assumption is that once an I/O has entered
the error handler path without having completed in the target, the
requirement on the driver is that all use of the sas_task must end.
Beyond that, recovery of operation is dependent on libsas and other
components to reset, rediscover and reconfigure the device before normal
operation can restart. In the driver, this simplifying assumption meant
that the RNC management could be reduced to entry into the suspended
state, terminating the targeted I/O request, and resuming the RNC as
needed for device-specific management such as an SSP Abort Task or LUN
Reset Management request.

* pm-sleep:
PM / Hibernate: Use get_gendisk to verify partition if resume_file is integer format
|
|
integer format
Sometimes resume= parameter comes in integer style (e.g. major:minor)
and then name_to_dev_t can not detect partition properly. (especially
async device like usb, mmc).
This patch calls get_gendisk() if resumewait is true and resume_file
is in integer format to work around this problem.

Hardware with MCA bus is limited to 386 and 486 class machines
that are now 20+ years old and typically with less than 32MB
of memory. A quick search on the internet, and you see that
even the MCA hobbyist/enthusiast community has lost interest
in the early 2000 era and never really even moved ahead from
the 2.4 kernels to the 2.6 series.
This deletes anything remaining related to CONFIG_MCA from core
kernel code and from the x86 architecture. There is no point in
carrying this any further into the future.
One complication to watch for is inadvertently scooping up
stuff relating to machine check, since there is overlap in
the TLA name space (e.g. arch/x86/boot/mca.c).

The support for CONFIG_MCA is being removed, since the 20
year old hardware simply isn't capable of meeting today's
software demands on CPU and memory resources.
This commit removes the MCA specific SCSI drivers, and the
MCA specific portions of code in dual role ISA/MCA drivers.
Also, the MCA specific SCSI documentation is removed.
