Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi-misc-2.6

Pull SCSI updates from James Bottomley:
 "This is primarily another round of driver updates (lpfc, bfa, fcoe,
  ipr) plus a new ufshcd driver.  There shouldn't be anything
  controversial in here (The final deletion of scsi proc_ops which
  caused some build breakage has been held over until the next merge
  window to give us more time to stabilise it).

  I'm afraid, with me moving continents at exactly the wrong time,
  anything submitted after the merge window opened has been held over to
  the next merge window."
