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

Pull more SCSI updates from James Bottomley:
 "This is mostly stuff which missed the first pull request because it
  needed to incubate longer.  It's mainly made up of the ncr 5380 rework
  but also has a few assorted bug fixes"
