       "Much smaller batch of fixes this week.
      
        Biggest one is a revert of an OMAP display change that removed some
        non-DT pinmux code that was still needed for 3.13 to get DSI displays
        to work.
      
        There's also a fix that resolves some misdescribed GPIO controller
        resources on shmobile.  The rest are mostly smaller fixes, a couple of
        MAINTAINERS updates, etc"

       "I've put these two patches plus Linus's change through a round of

      aio: clean up and fix aio_setup_ring page mapping · 3dc9acb6
      Linus Torvalds authored
      Since commit 36bc08cc ("fs/aio: Add support to aio ring pages
      migration") the aio ring setup code has used a special per-ring backing
      inode for the page allocations, rather than just using random anonymous
      pages.
      
      However, rather than remembering the pages as it allocated them, it
      would allocate the pages, insert them into the file mapping (dirty, so
      that they couldn't be free'd), and then forget about them.  And then to
      look them up again, it would mmap the mapping, and then use
      "get_user_pages()" to get back an array of the pages we just created.
      
      Now, not only is that incredibly inefficient, it also leaked all the
      pages if the mmap failed (which could happen due to excessive number of
      mappings, for example).
      
      So clean it all up, making it much more straightforward.  Also remove
      some left-overs of the previous (broken) mm_populate() usage that was
      removed in commit d6c355c7 ("aio: fix race in ring buffer page
      lookup introduced by page migration support") but left the pointless and
      now misleading MAP_POPULATE flag around.

      aio/migratepages: make aio migrate pages sane · 8e321fef
      Benjamin LaHaise authored
      The arbitrary restriction on page counts offered by the core
      migrate_page_move_mapping() code results in rather suspicious looking
      fiddling with page reference counts in the aio_migratepage() operation.
      To fix this, make migrate_page_move_mapping() take an extra_count parameter
      that allows aio to tell the code about its own reference count on the page
      being migrated.
      
      While cleaning up aio_migratepage(), make it validate that the old page
      being passed in is actually what aio_migratepage() expects to prevent
      misbehaviour in the case of races.

      Benjamin LaHaise authored
      e34ecee2 reworked the percpu reference
      counting to correct a bug trinity found.  Unfortunately, the change lead
      to kioctxes being leaked because there was no final reference count to
      put.  Add that reference count back in to fix things.

      Don't set the INITRD_COMPRESS environment variable automatically · b7000ade
      Linus Torvalds authored
      Commit 1bf49dd4 ("./Makefile: export initial ramdisk compression
      config option") started setting the INITRD_COMPRESS environment variable
      depending on which decompression models the kernel had available.
      
      That is completely broken.
      
      For example, we by default have CONFIG_RD_LZ4 enabled, and are able to
      decompress such an initrd, but the user tools to *create* such an initrd
      may not be availble.  So trying to tell dracut to generate an
      lz4-compressed image just because we can decode such an image is
      completely inappropriate.
