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

Pull SCSI updates from James Bottomley:
 "This is the usual grab bag of driver updates (lpfc, hpsa,
  megaraid_sas, cxgbi, be2iscsi) plus an assortment of minor updates.

  There is also one new driver: the Cisco snic.  The advansys driver has
  been rewritten to get rid of the warning about converting it to the
  DMA API, the tape statistics patch got in and finally, there's a
  resuffle of SCSI header files to separate more cleanly initiator from
  target mode (and better share the common definitions)"
