[GIT PULL] Block driver bits for 3.5

[Jens Axboe <jaxboe@fusionio.com>]

Hi Linus,

On top of the for-3.5/core pull request, here are the driver related
changes for 3.5. It contains:

- The floppy changes from Jiri. Jiri is now also marked as the
  maintainer of floppy.c, I shall be publically branding his forehead
  with red hot iron at the next opportune moment.

- A batch of drbd updates and fixes from the linbit crew, as well as
  fixes from others.

- Two small fixes for xen-blkfront courtesy of Jan.

Please pull.
