SCSI for-linus on 20121002

Browse source 
This is a large set of updates, mostly for drivers (qla2xxx [including support
 for new 83xx based card], qla4xxx, mpt2sas, bfa, zfcp, hpsa, be2iscsi, isci,
 lpfc, ipr, ibmvfc, ibmvscsi, megaraid_sas).  There's also a rework for tape
 adding virtually unlimited numbers of tape drives plus a set of dif fixes for
 sd and a fix for a live lock on hot remove of SCSI devices.
 
 This round includes a signed tag pull of isci-for-3.6
