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 most important feature of this patch set is the new async
  infrastructure that makes sure async_synchronize_full() synchronizes
  all domains and allows us to remove all the hacks (like having
  scsi_complete_async_scans() in the device base code) and means that
  the async infrastructure will "just work" in future.

  The rest is assorted driver updates (aacraid, bnx2fc, virto-scsi,
  megaraid, bfa, lpfc, qla2xxx, qla4xxx) plus a lot of infrastructure
  work in sas and FC.

  Signed-off-by: James Bottomley <JBottomley@Parallels.com>"
