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

Pull SCSI updates from James Bottomley:
 "This is mostly updates of the usual suspects: lpfc, qla2xxx, hisi_sas,
  megaraid_sas, zfcp and a host of minor updates.

  The major driver change here is the elimination of the block based
  cciss driver in favour of the SCSI based hpsa driver (which now drives
  all the legacy cases cciss used to be required for). Plus a reset
  handler clean up and the redo of the SAS SMP handler to use bsg lib"
