Merge branch 'sbp-target-merge' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending

Pull sbp-2 (firewire) target mode support from Nicholas Bellinger:
 "The FireWire SBP-2 Target is a driver for using an IEEE-1394
  connection as a SCSI transport.  This module uses the SCSI Target
  framework to expose LUNs to other machines attached to a FireWire bus,
  in effect acting as a FireWire hard disk similar to FireWire Target
  Disk mode on many Apple computers.

  Also included are the two drivers/firewire/ patches required by
  sbp-target to access fw_request fabric speed needed for mgt_agent
  TCODE_WRITE_BLOCK_REQUEST ops, and exporting fw_card kref logic used
  when creating/destroying active session references to individual
  endpoints.

  A credit goes to Chris in being able to get this code up and running
  so quickly w/o any target core changes, and special thanks goes out to
  Stefan Richter + Clemens Ladisch + Andy Grover for their help in
  getting this driver ready for mainline.  Also, one of Chris's goals
  was to be able to connect sbp-target to a PowerPC based MacOS-X based
  client, that he accomplished along the way in this obligatory
  screenshot:

  Great work Chris + linux-1394 team !!"
