SCSI for-linus on 20130510

Browse Source 
This is the final round of SCSI patches for the merge window.  It consists
 mostly of driver updates (bnx2fc, ibmfc, fnic, lpfc, be2iscsi, pm80xx, qla4x
 and ipr).  There's also the power management updates that complete the patches
 in Jens' tree, an iscsi refcounting problem fix from the last pull, some dif
 handling in scsi_debug fixes, a few nice code cleanups and an error handling
 busy bug fix.
