[GIT PULL] 2nd round block driver updates for 3.13-rc1

[Jens Axboe]

Hi Linus,

As mentioned in the original pull request, the bcache bits were pulled
because of their dependency on the immutable bio vecs. Kent redid this
part and resubmitted it, so here's the 2nd round of (mostly) driver
updates for 3.13. It contains:

- The bcache work from Kent.

- Conversion of virtio-blk to blk-mq. This removes the bio and request
  path, and substitutes with the blk-mq path instead. The end result
  almost 200 deleted lines. Patch is acked by Asias and Christoph, who
  both did a bunch of testing.

- A removal of bootmem.h include from Grygorii Strashko, part of a
  larger series of his killing the dependency on that header file.

- Removal of __cpuinit from blk-mq from Paul Gortmaker.


Please pull!
