Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi

Pull first round of SCSI updates from James Bottomley:
 "The patch set is mostly driver updates (usf, zfcp, lpfc, mpt2sas,
  megaraid_sas, bfa, ipr) and a few bug fixes.  Also of note is that the
  Buslogic driver has been rewritten to a better coding style and 64 bit
  support added.  We also removed the libsas limitation on 16 bytes for
  the command size (currently no drivers make use of this)"
