SCSI misc on 20151105 

This patch includes a couple of minor fixes, some core changes to help issues
 we're still seeing with the suspend/resume code and updates to lpfc and
 cxlflash.

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

Pull SCSI updates from James Bottomley:
 "First round of SCSI updates for the 4.4 merge window.

  This batch includes a couple of minor fixes, some core changes to help
  issues we're still seeing with the suspend/resume code and updates to
  lpfc and cxlflash.

  We're (actually Martin Petersen is) trying to wrangle a mpt2/mpt3sas
  merger for the merge window which will help enormously with the
  maintenance burden, so there will be another round before it closes"

* The READ_CAP16 can take quite a while to complete. Should an EEH occur while

* infinitely waiting for this ioctl thread. To avoid this behavior, temporarily
* unmark this thread as an ioctl thread by releasing the ioctl read semaphore.
* This will allow the EEH handler to proceed with a recovery while this thread
* is still running. Once the scsi_execute() returns, reacquire the ioctl read
* semaphore and check the adapter state in case it changed while inside of
* scsi_execute(). The state check will wait if the adapter is still being
* recovered or return a failure if the recovery failed. In the event that the
* adapter reset failed, simply return the failure as the ioctl would be unable
* to continue.
