ARM: DRA7: Reuse all of PRCM and MPUSS SMP infra
Linux 3.11-rc5
btrfs: don't loop on large offsets in readdir
Btrfs: check to see if root_list is empty before adding it to dead roots
Btrfs: release both paths before logging dir/changed extents
Btrfs: allow splitting of hole em's when dropping extent cache
Btrfs: make sure the backref walker catches all refs to our extent
Btrfs: fix backref walking when we hit a compressed extent
Btrfs: do not offset physical if we're compressed
Btrfs: fix extent buffer leak after backref walking
Btrfs: fix a bug of snapshot-aware defrag to make it work on partial extents
btrfs: fix file truncation if FALLOC_FL_KEEP_SIZE is specified
dlm: kill the unnecessary and wrong device_close()->recalc_sigpending()
