SCSI for-linus on 20141208

Browse source 
This patch is the usual mix of driver updates (srp, ipr, scsi_debug, NCR5380,
 fnic, 53c974, ses, wd719x, hpsa, megaraid_sas).  Of those, wd7a9x is new and
 53c974 is a rewrite of the old tmscsim driver and the extensive work by Finn
 Thain rewrites all the NCR5380 based drivers.  There's also extensive
 infrastructure updates: a new logging infrastructure for sense information and
 a rewrite of the tagged command queue API and an assortment of minor updates.
