      Pull ARM SoC driver changes from Olof Johansson:
       "SoC-near driver changes that we're merging through our tree.  Mostly
        because they depend on other changes we have staged, but in some cases
        because the driver maintainers preferred that we did it this way.
      
        This contains a largeish cleanup series of the omap_l3_noc bus driver,
        cpuidle rework for Exynos, some reset driver conversions and a long
        branch of TI EDMA fixes and cleanups, with more to come next release.
      
        The TI EDMA cleanups is a shared branch with the dmaengine tree, with
        a handful of Davinci-specific fixes on top.
      
        After discussion at last year's KS (and some more on the mailing
        lists), we are here adding a drivers/soc directory.  The purpose of
        this is to keep per-vendor shared code that's needed by different
        drivers but that doesn't fit into the MFD (nor drivers/platform)
        model.  We expect to keep merging contents for this hierarchy through
        arm-soc so we can keep an eye on what the vendors keep adding here and
        not making it a free-for-all to shove in crazy stuff"

      Pull ARM SoC board support updates from Olof Johansson:
       "The bulk of this branch is updates for Renesas Shmobile.  They are
        still doing some enablement for classic boards first, and then come up

        hardware.  Not necessarily a bad way to go about it, and they're
        looking at moving some of the temporary board code resulting from it
        to drivers/staging instead to avoid the churn here.
      
        As a result of the shmobile clock cleanups, we end up merging quite a

        in the cleanup branch due to the other board changes depending on it"

         - Multi-cluster power management for Samsung Exynos, adding support

         - SMP support for Marvell Armada 375 and 38x
      
         - SMP rework on Allwinner A31
      
         - Xilinx Zynq support for SOC_BUS, big endian
      
         - Marvell orion5x platform cleanup, modernizing the implementation
           and moving to DT.
      
         - _Finally_ moving Samsung Exynos over to support MULTIPLATFORM, so
           that their platform can be enabled in the same kernel binary as
           most of the other v7 platforms in the tree.  \o/

       "Now that the core bits are in, here's the pull request for the driver
        related changes for 3.16.  Nothing out of the ordinary here, mostly
        business as usual.  There are a few pulls of for-3.16/core into this
        branch, which were done when the blk-mq was modified after the
        mtip32xx conversion was put in.
      
        The pull request contains:
      
         - skd and cciss converted to use pci_enable_msix_exact().  From
           Alexander Gordeev.
      
         - A few mtip32xx fixes from Asai @ Micron.
      
         - The conversion of mtip32xx from make_request_fn to blk-mq, and a
           later small fix for that conversion on quiescing for non-queued IO.
           From me.
      
         - A fix for bsg to use an exported function to check whether this
           driver is request based or not.  Needed updating for blk-mq, which
           is request based, but does not have a request_fn hook.  From me.
      
         - Small floppy bug fix from Jiri.
      
         - A series of cleanups for the cdrom uniform layer from Joe Perches.
           Gets rid of various old ugly macros, making the code conform more
           to the modern coding style.

           Philipp Reisner).
      
         - A use-after-free fix for null_blk from Ming Lei.
      
         - Also from Ming Lei is a performance patch for virtio-blk, which can
           net us a 3x win on kvm platforms where world notification is
           expensive.
      
         - Ming Lei also fixed a stall issue in virtio-blk, due to a race
           between queue start/stop and resource limits.

      Pull block core updates from Jens Axboe:
       "It's a big(ish) round this time, lots of development effort has gone
        into blk-mq in the last 3 months.  Generally we're heading to where
        3.16 will be a feature complete and performant blk-mq.  scsi-mq is
        progressing nicely and will hopefully be in 3.17.  A nvme port is in
        progress, and the Micron pci-e flash driver, mtip32xx, is converted
        and will be sent in with the driver pull request for 3.16.
      
        This pull request contains:
      
         - Lots of prep and support patches for scsi-mq have been integrated.
           All from Christoph.
      
         - API and code cleanups for blk-mq from Christoph.
      
         - Lots of good corner case and error handling cleanup fixes for
           blk-mq from Ming Lei.
      
         - A flew of blk-mq updates from me:
      
           * Provide strict mappings so that the driver can rely on the CPU
             to queue mapping.  This enables optimizations in the driver.
      
           * Provided a bitmap tagging instead of percpu_ida, which never
             really worked well for blk-mq.  percpu_ida relies on the fact
             that we have a lot more tags available than we really need, it
             fails miserably for cases where we exhaust (or are close to
             exhausting) the tag space.
      
           * Provide sane support for shared tag maps, as utilized by scsi-mq
      
           * Various fixes for IO timeouts.
      
           * API cleanups, and lots of perf tweaks and optimizations.
      
         - Remove 'buffer' from struct request.  This is ancient code, from
           when requests were always virtually mapped.  Kill it, to reclaim
           some space in struct request.  From me.
      
         - Remove 'magic' from blk_plug.  Since we store these on the stack
           and since we've never caught any actual bugs with this, lets just
           get rid of it.  From me.
      
         - Only call part_in_flight() once for IO completion, as includes two
           atomic reads.  Hopefully we'll get a better implementation soon, as
           the part IO stats are now one of the more expensive parts of doing
           IO on blk-mq.  From me.
      
         - File migration of block code from {mm,fs}/ to block/.  This
           includes bio.c, bio-integrity.c, bounce.c, and ioprio.c.  From me,
           from a discussion on lkml.
      
        That should describe the meat of the pull request.  Also has various
        little fixes and cleanups from Dave Jones, Shaohua Li, Duan Jiong,
        Fengguang Wu, Fabian Frederick, Randy Dunlap, Robert Elliott, and Sam
        Bradshaw"

      Merge tag 'gpio-v3.16-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio into next
      
      Pull GPIO updates from Linus Walleij:
       "This is the bulk of GPIO changes for the v3.16 series.
      
        There is a lot of action in the GPIO subsystem doing refactorings and
        cleanups, almost as many deletions as insertions and minor feature
        growth and no new drivers this time.  Which is actually pretty nice.
        Some GPIO-related stuff will come in through the pin control tree as
        well.
      
        Details:
      
         - We are finalizing and fixing up the gpiochip irqchip helpers
           bringing a helpful irqchip implementation into the gpiolib core and
           avoiding duplicate code and, more importantly, duplicate bug fixes:
      
           * Support for using the helpers with threaded interrupt handlers as
             used on sleeping GPIO-irqchips
      
           * Do not set up hardware triggers for edges or levels if the
             default IRQ type is IRQ_TYPE_NONE - some drivers would exploit
             the fact that you could get default initialization of the IRQ
             type from the core at probe() but if no default type is set up
             from the helper, we should not call the driver to configure
             anything.  Wait until a consumer requests the interrupt instead.
      
           * Make the irqchip helpers put the GPIO irqs into their own lock
             class.  The GPIO irqchips can often emit (harmless, but annoying)
             lockdep warnings about recursions when they are in fact just
             cascaded IRQs.  By putting them into their own lock class we help
             the lockdep core to keep track of things.
      
           * Switch the tc3589x GPIO expanders to use the irqchip helpers
      
           * Switch the OMAP GPIO driver to use the irqchip helpers
      
           * Add some documentation for the irqchip helpers
      
           * select IRQ_DOMAIN when using the helpers since some platforms may
             not be using this by default and it's a strict dependency.
      
         - Continued GPIO descriptor refactoring:
      
           * Remove the one instance of gpio_to_desc() from the device tree
             code, making the OF GPIO code use GPIO descriptors only.
      
           * Introduce gpiod_get_optional() and gpiod_get_optional_index()
             akin to the similar regulator functions for cases where the use
             of GPIO is optional and not strictly required.
      
           * Make of_get_named_gpiod_flags() private - we do not want to
             unnecessarily expose APIs to drivers that make the gpiolib harder
             than necessary to maintain and refactor.  Privatize this
             function.
      
         - Support "-gpio" suffix for the OF GPIO retrieveal path.  We used to
           look for "foo-gpios" or just "gpios" in device tree nodes, but it
           turns out that some drivers with a single GPIO line will just state
           "foo-gpio" (singularis).  Sigh.  Support this with a fallback
           looking for it, as this simplifies driver code and handles it in
           core code.
      
         - Switch the ACPI GPIO core to fetch GPIOs with the *_cansleep
           function variants as the GPIO operation region handler can sleep,
           and shall be able to handle gpiochips that sleep.
      
         - Tons of cleanups and janitorial work from Jingoo Han, Axel Lin,
           Javier Martinez Canillas and Abdoulaye Berthe.  Notably Jingoo cut
           off a ton of pointless OOM messages.
      
         - Incremental development and fixes for various drivers, nothing
           really special here"

      drm/radeon: Resume fbcon last · 18ee37a4

          drm/crtc-helpers: fix dpms on logic
      
      which was merged into 3.15-rc1, broke resume on radeons. Strangely git
      bisect lead everyone to
      
      commit 25f397a4
      Author: Daniel Vetter <daniel.vetter@ffwll.ch>
      Date:   Fri Jul 19 18:57:11 2013 +0200
      
          drm/crtc-helper: explicit DPMS on after modeset
      
      which was merged long ago and actually part of 3.14.
      
      Digging deeper I've noticed (again) that the call to
      drm_helper_resume_force_mode in the radeon resume handlers was a no-op
      previously because everything gets shut down on suspend. radeon does
      this with explicit calls to drm_helper_connector_dpms with DPMS_OFF.
      But with 177c we now force the dpms state to ON, so suddenly
      resume_force_mode actually forced the crtcs back on.
      
      This is the intention of the change after all, the problem is that
      radeon resumes the fbdev console layer _before_ restoring the display,
      through calling fb_set_suspend. And fbcon does an immediate ->set_par,
      which in turn causes the same forced mode restore to happen.
      
      Two concurrent modeset operations didn't lead to happiness. Fix this
      by delaying the fbcon resume until the end of the readeon resum
      functions.
      
      v2: Fix up a bit of the spelling fail.
