      Pull MMC updates from Ulf Hansson:
       "MMC core:
            - Fix ABI regression of MMC BLK ioctl
            - Remove the unused MMC_DATA_STREAM flag
            - Enable asynchronous system PM for the host device
            - Minor fixes and clean-ups
      
        SDHCI host:
           Throughout the years, the numbers of SDHCI variants have increased
           and so has also the numbers of SDHCI callbacks/quirks.  The purpose
           of these callbacks/quirks were to enable SDHCI to deal with variant
           specific requirements, but unfortunate this method didn't scale.
           Instead we have ended up with a mess.  Not only did the code become
           suboptimal but also highly fragile.
      
           Lately many discussions of how to move forward with SDHCI has taken
           place at the MMC mailing list.  Step by step, we aim to turn
           SDHCI's common code into a set of library functions.  This will
           enable for optimizations and allow some of the existing callbacks
           and quirks to be removed, which also should help to make the code
           less fragile.
      
           Therefore I am also really pleased to announce that Adrian Hunter
           (Intel) has volunteered to step in as the maintainer for SDHCI.
      
           Future wise, I hope the community around SDHCI will continue to
           grow and that this release cycle can be the starting point of
           moving SDHCI into a better shape.  As a matter of fact, already in
           this cycle the re-factoring has begun, but of course there are also
           fixes and new features included.  Some highlights:
      
            - sdhci-iproc: Add support for Broadcom's BCM2835 eMMC IP
            - sdhci-acpi: Add support for QCOM controllers
            - sdhci-pic32: Add new SDHCI variant for PIC32MZDA
      
        Other hosts:
            - atmel-mci: Fix a NULL pointer dereference
            - mediatek: Add SD write-protect support
            - mmc_spi: Fix card detect in GPIO case
            - tmio/sdhi: Add r8a7795 support
            - tmio/sdhi: Some fixes and clean-ups
            - dw_mmc: Add HW reset support

      [media] vsp1: use proper dma alloc/free functions · 770c4c11
      Linus Torvalds authored
      I noticed this while merging the drm tree and checking for stragglers:
      the vsp1 driver still used dma_[alloc|free]_writecombine() that got
      renamed in commit f6e45661 ("dma, mm/pat: Rename
      dma_*_writecombine() to dma_*_wc()")
      
      I should have noticed back in the media merge (commit bace3db5), but
      better late than never.

      Pull arm[64] perf updates from Will Deacon:
       "I have another mixed bag of ARM-related perf patches here.
      
        It's about 25% CPU and 75% interconnect, but with drivers/bus/

        to keep all of these PMU patches together.  I suspect a whole load of
        code from drivers/bus/arm-* can be moved under drivers/perf/, so
        that's on the radar for the future.

      Linus Torvalds authored
      Pull xfs updates from Dave Chinner:
       "There's quite a lot in this request, and there's some cross-over with
        ext4, dax and quota code due to the nature of the changes being made.
      
        As for the rest of the XFS changes, there are lots of little things
        all over the place, which add up to a lot of changes in the end.
      
        The major changes are that we've reduced the size of the struct
        xfs_inode by ~100 bytes (gives an inode cache footprint reduction of
        >10%), the writepage code now only does a single set of mapping tree
        lockups so uses less CPU, delayed allocation reservations won't
        overrun under random write loads anymore, and we added compile time
        verification for on-disk structure sizes so we find out when a commit
        or platform/compiler change breaks the on disk structure as early as
        possible.
      
        Change summary:
      
         - error propagation for direct IO failures fixes for both XFS and
           ext4
         - new quota interfaces and XFS implementation for iterating all the
           quota IDs in the filesystem
         - locking fixes for real-time device extent allocation
         - reduction of duplicate information in the xfs and vfs inode, saving
           roughly 100 bytes of memory per cached inode.
         - buffer flag cleanup
         - rework of the writepage code to use the generic write clustering
           mechanisms
         - several fixes for inode flag based DAX enablement
         - rework of remount option parsing
         - compile time verification of on-disk format structure sizes
         - delayed allocation reservation overrun fixes
         - lots of little error handling fixes
         - small memory leak fixes
         - enable xfsaild freezing again"
