Pull block IO driver changes from Jens Axboe: - 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 * 'for-3.14/drivers' of git://git.kernel.dk/linux-block: (47 commits) mg_disk: Spelling s/finised/finished/ null_blk: Null pointer deference problem in alloc_page_buffers mtip32xx: Correctly handle security locked condition mtip32xx: Make SGL container per-command to eliminate high order dma allocation drivers/block/loop.c: fix comment typo in loop_config_discard drivers/block/cciss.c:cciss_init_one(): use proper errnos drivers/block/paride/pg.c: underflow bug in pg_write() drivers/block/sx8.c: remove unnecessary pci_set_drvdata() drivers/block/sx8.c: use module_pci_driver() floppy: bail out in open() if drive is not responding to block0 read bcache: Fix auxiliary search trees for key size > cacheline size bcache: Don't return -EINTR when insert finished bcache: Improve bucket_prio() calculation bcache: Add bch_bkey_equal_header() bcache: update bch_bkey_try_merge bcache: Move insert_fixup() to btree_keys_ops bcache: Convert sorting to btree_keys bcache: Convert debug code to btree_keys bcache: Convert btree_iter to struct btree_keys bcache: Refactor bset_tree sysfs stats ...
