Subject: [GIT PULL] Block drivers bits for 3.15

Hi Linus,

On top of the core pull request, here's the pull request for the driver
related changes for 3.15. It contains:

- Improvements for msi-x registration for block drivers (mtip32xx, skd,
  cciss, nvme) from Alexander Gordeev.

- A round of cleanups and improvements for drbd from Andreas
  Gruenbacher and Rashika Kheria.

- A round of clanups and improvements for bcache from Kent.

- Removal of sleep_on() and friends in DAC960, ataflop, swim3 from Arnd
  Bergmann.

- Bug fix for a bug in the mtip32xx async completion code from Sam
  Bradshaw.

- Bug fix for accidentally bouncing IO on 32-bit platforms with mtip32xx
  from Felipe Franciosi.

Please pull!
