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

Pull more SCSI updates from James Bottomley:
 "Six late arriving patches for the merge window. Five are minor
  assorted fixes and updates.

  The IPR driver change removes SATA support, which will now allow a
  major cleanup in the ATA subsystem because it was the only driver
  still using the old attachment mechanism. The driver is only used on
  power systems and SATA was used to support a DVD device, which has
  long been moved to a different hba. IBM chose this route instead of
  porting ipr to the newer SATA interfaces"
