      Linus Torvalds authored
      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.

             configuring the parameters for DMA by reading the capabilities of
             the DMA controller which removes some guesswork and magic numbers
             from drivers.
           * 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.
           * Support for using async register I/O in DAPM, reducing the time
             taken to implement power transitions on systems that support it.

       "Lots of driver updates here plus some nice new core features, the main
        one being the first:
      
         - Enable support for providing a dummy regulator when we know that
           one must exist for the device to be functional.  This makes it much
           easier to add regulator support to drivers since we don't require
           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.
         - Allow MFDs to distribute regulator supplies to child devices so we
           don't have to expose the internal structure of MFDs outside of the
           driver.
         - Managed registeration for regulators"

       "Main changes:
      
         - Add support for earlyprintk=efi which uses the EFI framebuffer.
           Very useful for debugging boot problems.
      
         - EFI stub support for large memory maps (more than 128 entries)
      
         - EFI ARM support - this was mostly done by generalizing x86 <-> ARM
           platform differences, such as by moving x86 EFI code into
           drivers/firmware/efi/ and sharing it with ARM.

      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.

              build-id cache support, multi map 'call' instruction navigation
              fixes, kcore address validation, objdump workarounds.  From
              Adrian Hunter.
      
            . Show progress on histogram collapsing, that can take a long
              time, from Namhyung Kim.
      
            . Add --max-stack option to limit callchain stack scan in 'top'
              and 'report', improving callchain processing when reducing the

              From Arnaldo Carvalho de Melo.
      
            . Show VFS path associated with fd in live sessions, using a
              'vfs_getname' 'perf probe' created dynamic tracepoint or by
              looking at /proc/pid/fd, from Arnaldo Carvalho de Melo.

              Arnaldo Carvalho de Melo.
      
            . Implement more compact 'trace' output by suppressing zeroed
              args, from Arnaldo Carvalho de Melo.

            . 'perf trace' now emits hints as to why tracing is not possible,
              helping the user to setup the system to allow tracing in the
              desired permission granularity, telling if the problem is due to

              !root, /proc/sys/kernel/perf_event_paranoit value, etc.  From
              Arnaldo Carvalho de Melo.
      
         * 'perf record' enhancements:
      
            . Check maximum frequency rate for record/top, emitting better
              error messages, from Jiri Olsa.
      
            . 'perf record' code cleanups, from David Ahern.
      
            . Improve write_output error message in 'perf record', from Adrian

              Pekka Enberg.
      
         * 'perf probe' enhancements:
      
            . Support "$vars" meta argument syntax for local variables,
              allowing asking for all possible variables at a given probe
              point to be collected when it hits, from Masami Hiramatsu.
      
         * 'perf sched' enhancements:
      
            . Address the root cause of that 'perf sched' stack initialization
              build slowdown, by programmatically setting a big array after
              moving the global variable back to the stack.  Fix from Adrian
              Hunter.
      
         * 'perf script' enhancements:

      Pull RCU updates from Ingo Molnar:
       "The main RCU changes in this cycle are:
      
         - Idle entry/exit changes, to throttle callback execution and other
           refinements to speed up kbuild, primarily to address performance
           issues located by Tibor Billes.
      
         - Grace-period related changes, primarily to aid in debugging,
           inspired by an -rt debugging session.
      
         - Code reorganization moving RCU's source files into its own
           kernel/rcu/ directory.
      
         - RCU documentation updates
      
         - Miscellaneous fixes.
