Commit df910390 authored by Linus Torvalds's avatar Linus Torvalds

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.

* The LXT Entry contains the physical LBA where the chunk starts (RLBA_BASE).
* AFU ORes the low order bits from the virtual LBA (offset into the chunk)
* with RLBA_BASE. The result is the physical LBA to be sent to storage.
* The LXT Entry also contains an index to a LUN TBL and a bitmask of which
* outgoing (FC) * ports can be selected. The port select bit-mask is ANDed
* with a global port select bit-mask maintained by the driver.
* In addition, it has permission bits that are ANDed with the
* RHT permissions to arrive at the final permissions for the chunk.
*
* LXT tables are allocated dynamically in groups. This is done to avoid
* a malloc/free overhead each time the LXT has to grow or shrink.
*
* Based on the current lxt_cnt (used), it is always possible to know
* how many are allocated (used+free). The number of allocated entries is
* not stored anywhere.
*
* The LXT table is re-allocated whenever it needs to cross into another group.
