SCSI for-linus on 20140609 

This patch consists of the usual driver updates (qla2xxx, qla4xxx, lpfc,
 be2iscsi, fnic, ufs, NCR5380) The NCR5380 is the addition to maintained status
 of a long neglected driver for older hardware.  In addition there are a lot of
 minor fixes and cleanups and some more updates to make scsi mq ready.
