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.

     * A refresh of the documentation.
     * Conversions of many drivers to direct regmap API usage in order
       to allow the ASoC level register I/O code to be removed, this
       will hopefully be completed by v3.14.

Pull regulator updates from Mark Brown:

     that the machine integration for all systems using the device be
     updated to provide regulators.
   - Substantial reduction in the amount of busy waiting done while
     waiting for enables to complete.

     don't have to expose the internal structure of MFDs outside of the

Pull regmap updates from Mark Brown:
 "The main thing this time around has been some improvments to async

     internally generated I/O, providing performance improvements for
     devices that can do async I/O.
   - An API for issuing a sequence of register writes as a single
     operation.  Some devices and buses can take advantage of this to do
     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.

        debugfs not being mounted or with not enough permission for
        !root, /proc/sys/kernel/perf_event_paranoit value, etc.  From
        Arnaldo Carvalho de Melo.

This reverts commit 8eba1842.

uv_trace() is not used by anything, nor is uv_trace_nmi_func, nor
uv_trace_func.

That's not how we do instrumentation code in the kernel: we add
tracepoints, printk()s, etc. so that everyone not just those with
magic kernel modules can debug a system.

So remove this unused (and misguied) piece of code.

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.

Randconfig build by Fengguang's robot army reported:

   drivers/built-in.o: In function `extlog_print':

The config had CONFIG_SMP=n so we picked up this definition from:

But boot_cpu_physical_apicid is defined in arch/x86/kernel/apic/apic.c
which is only built if CONFIG_X86_LOCAL_APIC=y.
