Linus Torvalds df910390e2 SCSI misc on 20150901 
This includes one new driver: cxlflash plus the usual grab bag of updates for
 the major drivers: qla2xxx, ipr, storvsc, pm80xx, hptiop, plus a few assorted
 fixes.

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

Pull first round of SCSI updates from James Bottomley:
 "This includes one new driver: cxlflash plus the usual grab bag of
  updates for the major drivers: qla2xxx, ipr, storvsc, pm80xx, hptiop,
  plus a few assorted fixes.

  There's another tranch coming, but I want to incubate it another few
  days in the checkers, plus it includes a mpt2sas separated lifetime
  fix, which Avago won't get done testing until Friday"

* tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (85 commits)
  aic94xx: set an error code on failure
  storvsc: Set the error code correctly in failure conditions
  storvsc: Allow write_same when host is windows 10
  storvsc: use storage protocol version to determine storage capabilities
  storvsc: use correct defaults for values determined by protocol negotiation
  storvsc: Untangle the storage protocol negotiation from the vmbus protocol negotiation.
  storvsc: Use a single value to track protocol versions
  storvsc: Rather than look for sets of specific protocol versions, make decisions based on ranges.
  cxlflash: Remove unused variable from queuecommand
  cxlflash: shift wrapping bug in afu_link_reset()
  cxlflash: off by one bug in cxlflash_show_port_status()
  cxlflash: Virtual LUN support
  cxlflash: Superpipe support
  cxlflash: Base error recovery support
  qla2xxx: Update driver version to 8.07.00.26-k
  qla2xxx: Add pci device id 0x2261.
  qla2xxx: Fix missing device login retries.
  qla2xxx: do not clear slot in outstanding cmd array
  qla2xxx: Remove decrement of sp reference count in abort handler.
  qla2xxx: Add support to show MPI and PEP FW version for ISP27xx.

* qla2x00_get_fcode_version() - Determine an FCODE image's version.
* @ha: HA context
* @pcids: Pointer to the FCODE PCI data structure
*
* The process of retrieving the FCODE version information is at best
* described as interesting.
*
* Within the first 100h bytes of the image an ASCII string is present
* which contains several pieces of information including the FCODE
* version. Unfortunately it seems the only reliable way to retrieve
* the version is by scanning for another sentinel within the string,
* the FCODE build date:
*
* ... 2.00.02 10/17/02 ...
*
* Returns QLA_SUCCESS on successful retrieval of version.
