Any user process callers of wait_for_completion() except global init
process might be chosen by the OOM killer while waiting for completion()
call by some other process which does memory allocation. See
CVE-2012-4398 "kernel: request_module() OOM local DoS" can happen.
When such users are chosen by the OOM killer when they are waiting for
completion() in TASK_UNINTERRUPTIBLE, the system will be kept stressed
due to memory starvation because the OOM killer cannot kill such users.
kthread_create() is one of such users and this patch fixes the problem
for kthreadd by making kthread_create() killable - the same approach
used for fixing CVE-2012-4398.

Pull GPIO changes from Linus Walleij:
"Here is the bulk of GPIO changes for the v3.13 development cycle.
I've got ACKs for the things that affect other subsystems (or it's my
own subsystem, like pinctrl). Most of that pertain to an attempt from
my side to consolidate and get rid of custom GPIO implementations in
the ARM tree. I will continue doing this.
The main change this time is the new GPIO descriptor API, background
for this can be found in Corbet's summary from this january in LWN:
http://lwn.net/Articles/533632/
Summary:
- Merged the GPIO descriptor API from Alexandre Courbot. This is a
first step toward trying to get rid of the global GPIO numberspace
for the future.
- Add an API so that driver can flag that a certain GPIO line is
being used by a irqchip backend for generating IRQs, so that we can
enforce checks, like not allowing users to switch that line to an
output at runtime, since this makes no sense. Implemented
corresponding calls in a few select drivers.
- ACPI GPIO cleanups, refactorings and switch to using the
descriptor-based interface.
- Support for the TPS80036 Palmas GPIO variant.
- A new driver for the Broadcom Kona GPIO SoC IP block.
- Device tree support for the PCF857x driver.
- A set of ARM GPIO refactorings with the goal of getting rid of a
bunch of custom GPIO implementations from the arch/arm/* tree:
* Move the IOP GPIO driver to the GPIO subsystem and fix all users
to use the gpiolib API for accessing GPIOs. Delete the old
custom GPIO implementation.
* Delete the unused custom PXA GPIO implemention.
* Convert all users of the IXP4 custom GPIO implementation to use
gpiolib and delete the custom implementation.
* Delete the custom Gemini GPIO implementation, also completely
unused.
- Various cleanups and renamings"

Pull pin control updates from Linus Walleij:
"Main pin control pull request for the v3.13 cycle.
The changes hitting arch/blackfin are ACKed by the Blackfin
maintainer, and the device tree bindings are ACKed to the extent
possible by someone from the device tree maintainers group.
- Blackfin ADI pin control driver, we move yet another architecture
under this subsystem umbrella.
- Incremental updates to the Renesas Super-H PFC pin control driver.
New subdriver for the r8a7791 SoC.
- Non-linear GPIO ranges from the gpiolib side of things, this
enabled simplified device tree bindings by referring entire groups
of pins on some pin controller to act as back-end for a certain
GPIO-chip driver.
- Add the Abilis TB10x pin control driver used on the ARC
architecture. Also the corresponding GPIO driver is merged through
this tree, so the ARC has full support for pins and GPIOs after
this.
- Subdrivers for Freescale i.MX1, i.MX27 and i.MX50 pin controller
instances. The i.MX1 and i.MX27 is an entirely new family
(silicon) of controllers whereas i.MX50 is a variant of the
previous supported controller.
- Then the usual slew of fixes, cleanups and incremental updates"
The ARC DT changes are apparently still pending, that hopefully gets
sorted out in a timely manner.

devices that can do async I/O.
- An API for issuing a sequence of register writes as a single

the I/O faster.

repeated IPs or which move registers around between revisions to

Pull perf updates from Ingo Molnar:
"As a first remark I'd like to note that the way to build perf tooling
has been simplified and sped up, in the future it should be enough for
you to build perf via:
cd tools/perf/
make install
(ie without the -j option.) The build system will figure out the
number of CPUs and will do a parallel build+install.
The various build system inefficiencies and breakages Linus reported
against the v3.12 pull request should now be resolved - please
(re-)report any remaining annoyances or bugs.

There is a race between stop_two_cpus, and the global stop_cpus.
It is possible for two CPUs to get their stopper functions queued
"backwards" from one another, resulting in the stopper threads
getting stuck, and the system hanging. This can happen because
queuing up stoppers is not synchronized.
This patch adds synchronization between stop_cpus (a rare operation),
and stop_two_cpus.
