       "A number of fixes:
      
        Patrik found a problem with preempt counting in the VFP assembly
        functions which can cause the preempt count to be upset.
      
        Nicolas fixed a problem with the parsing of the DT when it straddles a
        1MB boundary.
      
        Subhash Jadavani reported a problem with sparsemem and our highmem
        support for cache maintanence for DMA areas, and TI found a bug in
        their strongly ordered memory mapping type.
      
        Also, three fixes by way of Will Deacon's tree from Dave Martin for
        instruction compatibility and Marc Zyngier to fix hypervisor boot mode
        issues."

      Pull ARM SoC fixes from Olof Johansson:
       "Here's a long-pending fixes pull request for arm-soc (I didn't send
        one in the -rc4 cycle).
      
        The larger deltas are from:
      
         - A fixup of error paths in the mvsdio driver
      
         - Header file move for a driver that hadn't been properly converted
           to multiplatform on i.MX, which was causing build failures when
           included
      
         - Device tree updates for at91 dealing mostly with their new pinctrl
           setup merged in 3.8 and mistakes in those initial configs
      
        The rest are the normal mix of small fixes all over the place; sunxi,

      Btrfs: fix repeated delalloc work allocation · 1eafa6c7
      Miao Xie authored
      btrfs_start_delalloc_inodes() locks the delalloc_inodes list, fetches the
      first inode, unlocks the list, triggers btrfs_alloc_delalloc_work/
      btrfs_queue_worker for this inode, and then it locks the list, checks the
      head of the list again. But because we don't delete the first inode that it
      deals with before, it will fetch the same inode. As a result, this function
      allocates a huge amount of btrfs_delalloc_work structures, and OOM happens.
      
      Fix this problem by splice this delalloc list.

      Btrfs: fix missed transaction->aborted check · 2cba30f1
      Miao Xie authored
      First, though the current transaction->aborted check can stop the commit early
      and avoid unnecessary operations, it is too early, and some transaction handles
      don't end, those handles may set transaction->aborted after the check.
      
      Second, when we commit the transaction, we will wake up some worker threads to
      flush the space cache and inode cache. Those threads also allocate some transaction
      handles and may set transaction->aborted if some serious error happens.
      
      So we need more check for ->aborted when committing the transaction. Fix it.

      Btrfs: put csums on the right ordered extent · e58dd74b
      Josef Bacik authored
      I noticed a WARN_ON going off when adding csums because we were going over
      the amount of csum bytes that should have been allowed for an ordered
      extent.  This is a leftover from when we used to hold the csums privately
      for direct io, but now we use the normal ordered sum stuff so we need to
      make sure and check if we've moved on to another extent so that the csums
      are added to the right extent.  Without this we could end up with csums for
      bytenrs that don't have extents to cover them yet.  Thanks,

      Btrfs: use right range to find checksum for compressed extents · 192000dd
      Liu Bo authored
      For compressed extents, the range of checksum is covered by disk length,
      and the disk length is different with ram length, so we need to use disk
      length instead to get us the right checksum.

      Btrfs: fix panic when recovering tree log · b0175117
      Josef Bacik authored
      A user reported a BUG_ON(ret) that occured during tree log replay.  Ret was
      -EAGAIN, so what I think happened is that we removed an extent that covered
      a bitmap entry and an extent entry.  We remove the part from the bitmap and
      return -EAGAIN and then search for the next piece we want to remove, which
      happens to be an entire extent entry, so we just free the sucker and return.
      The problem is ret is still set to -EAGAIN so we trip the BUG_ON().  The
      user used btrfs-zero-log so I'm not 100% sure this is what happened so I've
      added a WARN_ON() to catch the other possibility.  Thanks,

      Btrfs: do not allow logged extents to be merged or removed · 201a9038
      Josef Bacik authored
      We drop the extent map tree lock while we're logging extents, so somebody
      could come in and merge another extent into this one and screw up our
      logging, or they could even remove us from the list which would keep us from
      logging the extent or freeing our ref on it, so we need to make sure to not
      clear LOGGING until after the extent is logged, and then we can merge it to
      adjacent extents.  Thanks,
