[GIT PULL] Core block IO bits for 3.15-rc

[Jens Axboe <axboe@fb.com>]

Hi Linus,

This is the pull request for the core block IO bits for the 3.15 kernel.
It's a smaller round this time, it contains:

- Various little blk-mq fixes and additions from Christoph and myself.

- Cleanup of the IPI usage from the block layer, and associated helper
  code. From Frederic Weisbecker and Jan Kara.

- Duplicate code cleanup in bio-integrity from Gu Zheng. This will give
  you a merge conflict, but that should be easy to resolve.

- blk-mq notify spinlock fix for RT from Mike Galbraith.

- A blktrace partial accounting bug fix from Roman Pen.

- Missing REQ_SYNC detection fix for blk-mq from Shaohua Li.


Please pull!
