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 (bnx2fc, ipr, lpfc, qla4) and a
  few bug fixes"

Pull delayed because google hates James, and sneakily considers his pull
requests spam. Why, google, why?
