[GIT PULL] Block IO driver changes for 3.14

[Jens Axboe <axboe@kernel.dk>]

Hi Linus,

This is the block driver pull request for 3.14. It contains:

- bcache update from Kent Overstreet.

- Two bcache fixes from Nicholas Swenson.

- cciss pci init error fix from Andrew.

- Underflow fix in the parallel IDE pg_write code from Dan Carpenter.
  I'm sure the 1 (or 0) users of that are now happy.

- Two PCI related fixes for sx8 from Jingoo Han.

- Floppy init fix for first block read from Jiri Kosina.

- pktcdvd error return miss fix from Julia Lawall.

- Removal of IRQF_SHARED from the SEGA Dreamcast CD-ROM code from
  Michael Opdenacker.

- Comment typo fix for the loop driver from Olaf Hering.

- Potential oops fix for null_blk from Raghavendra K T.

- Two fixes from Sam Bradshaw (Micron) for the mtip32xx driver, fixing
  an OOM problem and a problem with handling security locked conditions.


Please pull!
