xfs: updates for 4.10-rc1

Contained in this update:
 - DAX PMD vaults via iomap infrastructure
 - Direct-io support in iomap infrastructure
 - removal of now-redundant XFS inode iolock, replaced with VFS i_rwsem
 - synchronisation with fixes and changes in userspace libxfs code
 - extent tree lookup helpers
 - lots of little corruption detection improvements to verifiers
 - optimised CRC calculations
 - faster buffer cache lookups
 - deprecation of barrier/nobarrier mount options - we always use
   REQ_FUA/REQ_FLUSH where appropriate for data integrity now
 - cleanups to speculative preallocation
 - miscellaneous minor bug fixes and cleanups

Merge tag 'xfs-for-linus-4.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs

Pull xfs updates from Dave Chinner:
 "There is quite a varied bunch of stuff in this update, and some of it
  you will have already merged through the ext4 tree which imported the
  dax-4.10-iomap-pmd topic branch from the XFS tree.

  There is also a new direct IO implementation that uses the iomap
  infrastructure. It's much simpler, faster, and has lower IO latency
  than the existing direct IO infrastructure.

  Summary:
   - DAX PMD faults via iomap infrastructure
   - Direct-io support in iomap infrastructure
   - removal of now-redundant XFS inode iolock, replaced with VFS
     i_rwsem
   - synchronisation with fixes and changes in userspace libxfs code
   - extent tree lookup helpers
   - lots of little corruption detection improvements to verifiers
   - optimised CRC calculations
   - faster buffer cache lookups
   - deprecation of barrier/nobarrier mount options - we always use
     REQ_FUA/REQ_FLUSH where appropriate for data integrity now
   - cleanups to speculative preallocation
   - miscellaneous minor bug fixes and cleanups"
