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

Pull first round of SCSI updates from James Bottomley:
 "This is a large set of updates, mostly for drivers (qla2xxx [including
  support for new 83xx based card], qla4xxx, mpt2sas, bfa, zfcp, hpsa,
  be2iscsi, isci, lpfc, ipr, ibmvfc, ibmvscsi, megaraid_sas).

  There's also a rework for tape adding virtually unlimited numbers of
  tape drives plus a set of dif fixes for sd and a fix for a live lock
  on hot remove of SCSI devices.

  This round includes a signed tag pull of isci-for-3.6

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

Fix up trivial conflict in drivers/scsi/qla2xxx/qla_nx.c due to new PCI
helper function use in a function that was removed by this pull.
