Only set sc->rx.discard_next to rx_stats->rs_more when actually
discarding the current descriptor.
Also, fix a detection of broken descriptors:
First the code checks if the current descriptor is not done.
Then it checks if the next descriptor is done.
Add a check that afterwards checks the first descriptor again, because
it might have been completed in the mean time.
This fixes a regression introduced in
commit 723e711356b5a8a95728a890e254e8b0d47b55cf

Since commit 77873803363c "net_dma: mark broken" we no longer pin dma
engines active for the network-receive-offload use case. As a result
the ->free_chan_resources() that occurs after the driver self test no
longer has a NET_DMA induced ->alloc_chan_resources() to back it up. A
late firing irq can lead to ksoftirqd spinning indefinitely due to the
tasklet_disable() performed by ->free_chan_resources(). Only
->alloc_chan_resources() can clear this condition in affected kernels.
This problem has been present since commit 3e037454bcfa "I/OAT: Add
support for MSI and MSI-X" in 2.6.24, but is now exposed. Given the
NET_DMA use case is deprecated we can revisit moving the driver to use
threaded irqs. For now, just tear down the irq and tasklet properly by:
1/ Disable the irq from triggering the tasklet
2/ Disable the irq from re-arming
3/ Flush inflight interrupts
4/ Flush the timer
5/ Flush inflight tasklets

As mount() and kill_sb() is not a one-to-one match, we shoudn't get
ns refcnt unconditionally in sysfs_mount(), and instead we should
get the refcnt only when kernfs_mount() allocated a new superblock.
v2:
- Changed the name of the new argument, suggested by Tejun.
- Made the argument optional, suggested by Tejun.
v3:
- Make the new argument as second-to-last arg, suggested by Tejun.

Commit 7053aee26a35 "fsnotify: do not share events between notification
groups" used overflow event statically allocated in a group with the
size of the generic notification event. This causes problems because
some code looks at type specific parts of event structure and gets
confused by a random data it sees there and causes crashes.
Fix the problem by allocating overflow event with type corresponding to
the group type so code cannot get confused.

If the event queue overflows when we are handling permission event, we
will never get response from userspace. So we must avoid waiting for it.
Change fsnotify_add_notify_event() to return whether overflow has
happened so that we can detect it in fanotify_handle_event() and act
accordingly.

Currently we didn't initialize event's list head when we removed it from

pci_get_device() decrements the reference count of "from" (last
argument) so when we break off the loop successfully we have only one
device reference - and we don't know which device we have. If we want
a reference to each device, we must take them explicitly and let
the pci_get_device() walk complete to avoid duplicate references.
This is serious, as over-putting device references will cause
the device to eventually disappear. Without this fix, the kernel
crashes after a few insmod/rmmod cycles.
Tested on an Intel S7000FC4UR system with a 7300 chipset.

The reference count changes done by pci_get_device can be a little
misleading when the usage diverges from the most common scheme. The
reference count of the device passed as the last parameter is always
decreased, even if the function returns no new device. So if we are
going to try alternative device IDs, we must manually increment the
device reference count before each retry. If we don't, we end up
decreasing the reference count, and after a few modprobe/rmmod cycles
the PCI devices will vanish.
In other words and as Alan put it: without this fix the EDAC code
corrupts the PCI device list.

There are many places where ops->disable is called directly. Instead we
should use _regulator_do_disable() which also handles gpio regulators.
To be able to use the wrapper function from _regulator_force_disable(),
I moved the _notifier_call_chain() call from _regulator_do_disable() to
_regulator_disable(). This way, _regulator_force_disable() can use
different flags for _notifier_call_chain() without calling it twice.

There are some direct ops->enable in the regulator core driver. This is
a potential issue as the function _regulator_do_enable() handles gpio
regulators and the normal ops->enable calls. These gpio regulators are
simply ignored when ops->enable is called directly.
One possible bug is that boot-on and always-on gpio regulators are not
enabled on registration.
This patch replaces all ops->enable calls by _regulator_do_enable.

tcp_is_cwnd_limited() allows GSO/TSO enabled flows to increase
their cwnd to allow a full size (64KB) TSO packet to be sent.
Non GSO flows only allow an extra room of 3 MSS.
For most flows with a BDP below 10 MSS, this results in a bloat
of cwnd reaching 90, and an inflate of RTT.
Thanks to TSO auto sizing, we can restrict the bloat to the number
of MSS contained in a TSO packet (tp->xmit_size_goal_segs), to keep
original intent without performance impact.
Because we keep cwnd small, it helps to keep TSO packet size to their
optimal value.
Example for a 10Mbit flow, with low TCP Small queue limits (no more than
2 skb in qdisc/device tx ring)

Releasing the touchscreen lets the internal statemachine left in a wrong state.
Due to this the release coordinate will be reported again by accident when the next
touchscreen event happens. This change sets up the correct state when waiting
for the next touchscreen event.

A selective retransmission request (SRR) is a fibre-channel
protocol control request which provides support for requesting
retransmission of a data sequence in response to an issue such as
frame loss or corruption. These events are experienced
infrequently in fibre-channel based networks which makes
it difficult to test and assess codepaths which handle these
events.
We were fortunate enough, for some definition of fortunate, to
have a metro-area single-mode SAN link which, at 10 GBPS
sustained load levels, would consistently generate SRR's in
a SCST based target implementation using our SCST/in-kernel
Qlogic target interface driver. In response to an SRR the
in-kernel Qlogic target driver immediately panics resulting
in a catastrophic storage failure for serviced initiators.
The culprit was a debug statement in the qla_target.c file which
does not verify that a pointer to the SCSI CDB is not null.
The unchecked pointer dereference results in the kernel panic
and resultant system failure.
The other two references to the SCSI CDB by the SRR handling code
use a ternary operator to verify a non-null pointer is being
acted on. This patch simply adds a similar test to the implicated
debug statement.
This patch is a candidate for any stable kernel being maintained
since it addresses a potentially catastrophic event with
minimal downside.

Stephane reported that perf report and annotate failed to process data
using lots of (> 500) shared libraries. It was because of the limit on
number of open files (ulimit -n).
Currently when perf loads a DSO, it'll look for normal and dynamic
symbol tables. And if it fails to find out both tables, it'll iterate
all of possible symtab types. But many of them are useless since they
have no additional information and the problem is that it's not closing
those files even though they're not used. Fix it.

The TUI of perf report and top support annotation, but stdio and GTK
don't. So it should be checked before calling hist_entry__inc_addr_

perf annotate need it regardless of UI and sort keys, so the check
of whether to allocate resources should be on the tools that have
annotate as an option in the TUI, 'report' and 'top', not on the
function called by all of them.
It caused perf annotate on ppc64 to produce zero output, since the

The MLME code in mac80211 must track whether or not the AP changed
bandwidth, but if there's no change while tracking it shouldn't do
anything, otherwise regulatory updates can make it impossible to
connect to certain APs if the regulatory database doesn't match the
information from the AP. See the precise scenario described in the
code.
This still leaves some possible problems with CSA or if the AP
actually changed bandwidth, but those cases are less common and
won't completely prevent using it.

We had a bug discovered recently where an upper layer function
(cifs_iovec_write) could pass down a smb_rqst with an invalid amount of
data in it. The length of the SMB frame would be correct, but the rqst
struct would cause smb_send_rqst to send nearly 4GB of data.
This should never be the case. Add some sanity checking to the beginning
of smb_send_rqst that ensures that the amount of data we're going to
send agrees with the length in the RFC1002 header. If it doesn't, WARN()
and return -EIO to the upper layers.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC fixes from Olof Johansson:
"A collection of fixes for ARM platforms. Most are fixes for DTS
files, mostly from DT conversion on OMAP which is still finding a few
issues here and there.
There's a couple of small stale code removal patches that we usually
queue for the next release instead, but they seemed harmless enough to
bring in now.
Also, a fix for backlight on some PXA platforms, and a cache
configuration fix for Tegra, etc"
