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:
 "This patch set includes two large new drivers: mpt3sas (for the next
  gen fusion SAS hardware) and csiostor a FCoE offload driver for the
  Chelsio converged network cards (this includes some net changes which
  I've OK'd with DaveM).

  The rest of the patch is driver updates (qla2xxx, lpfc, hptiop,
  be2iscsi) plus a few assorted updates and bug fixes.

  We also have a Power Management rework in the Upper Layer Drivers
  preparatory to doing ACPI zero power optical devices, but the actual
  enabler is still being worked on.

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