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

Pull SCSI misc update from James Bottomley:
 "The patch contains the usual assortment of driver updates (be2iscsi,
  bfa, bnx2i, fcoe, hpsa, isci, lpfc, megaraid, mpt2sas, pm8001, sg)
  plus an assortment of other changes and fixes.  Also new is the fact
  that the isci update is delivered as a git merge (with signed tag)."

* tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (158 commits)
  isci: End the RNC resumption wait when the RNC is destroyed.
  isci: Fixed RNC bug that lost the suspension or resumption during destroy
  isci: Fix RNC AWAIT_SUSPENSION->INVALIDATING transition.
  isci: Manage the IREQ_NO_AUTO_FREE_TAG under scic_lock.
  isci: Remove obviated host callback list.
  isci: Check IDEV_GONE before performing abort path operations.
  isci: Restore the ATAPI device RNC management code.
  isci: Don't wait for an RNC suspend if it's being destroyed.
  isci: Change the phy control and link reset interface for HW reasons.
  isci: Added timeouts to RNC suspensions in the abort path.
  isci: Add protocol indicator for TMF requests.
  isci: Directly control IREQ_ABORT_PATH_ACTIVE when completing TMFs.
  isci: Wait for RNC resumption before leaving the abort path.
  isci: Fix RNC suspend call for SCI_RESUMING state.
  isci: Manage tag releases differently when aborting tasks.
  isci: Callbacks to libsas occur under scic_lock and are synchronized.
  isci: When in the abort path, defeat other resume calls until done.
  isci: Implement waiting for suspend in the abort path.
  isci: Make sure all TCs are terminated and cleaned in LUN reset.
  isci: Manage the LLHANG timer enable/disable per-device.
