Pull SCSI target fixes from Nicholas Bellinger:
 "These are mostly minor fixes this time around.  The iscsi-target CHAP
  big-endian bugfix and bump FD_MAX_SECTORS=2048 default patch to allow
  1MB sized I/Os for FILEIO backends on >= v3.5 code are both CC'ed to
  stable.

  Also, there is a persistent reservations regression that has recently
  been reported for >= v3.8.x code, that is currently being tracked down
  for v3.9."

* git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending:
  target/pscsi: Reject cross page boundary case in pscsi_map_sg
  target/file: Bump FD_MAX_SECTORS to 2048 to handle 1M sized I/Os
  tcm_vhost: Flush vhost_work in vhost_scsi_flush()
  tcm_vhost: Add missed lock in vhost_scsi_clear_endpoint()
  target: fix possible memory leak in core_tpg_register()
  target/iscsi: Fix mutual CHAP auth on big-endian arches
  target_core_sbc: use noop for SYNCHRONIZE_CACHE
