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

Pull SCSI updates from James Bottomley:
 "This patch set consists of the usual driver updates (ufs, storvsc,
  pm8001 hpsa).  It also has removal of the user space target driver
  code (everyone is using LIO now), a partial PCI MSI-X update, more
  multi-queue updates, conversion to 64 bit LUNs (so we could
  theoretically cope with any LUN returned by a device) and placeholder
  support for the ZBC device type (Shingle drives), plus an assortment
  of minor updates and bug fixes"
