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

Pull SCSI updates from James Bottomley:
 "This update includes the usual round of driver updates (fcoe, lpfc,
  ufs, qla2xxx, hisi_sas).  The most important other change is removing
  the flag to allow non-blk_mq on a per host basis (it's unused); there
  is still a global module parameter for all of SCSI just in case.

  The rest are an assortment of minor fixes and typo updates"

* tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (101 commits)
  scsi:libsas: fix oops caused by assigning a freed task to ->lldd_task

+- reg		: <registers mapping>
+- interrupts	: <interrupt mapping for UFS host controller IRQ>
