[GIT PULL] bcache for 3.14

[Kent Overstreet <kmo@daterainc.com>]

Jens, here's the updated bcache pull, rebased and retested on top of
your latest for-3.14/drivers branch. Only other change was a one liner
in the "bcache/md: Use raid stripe size" patch to update
blk_stack_limits(), as pointed out by Mike Snitzer.


The following changes since commit 54a387cb9e600256e50cb9e2209e7e4f06f464de:

  Merge branch 'for-3.14/core' into for-3.14/drivers (2014-01-08 09:32:45 -0700)
