Linus Torvalds acd53127c4 SCSI misc on 20150622
This is the usual grab bag of driver updates (lpfc, hpsa,
 megaraid_sas, cxgbi, be2iscsi) plus an assortment of minor updates.
 There are also one new driver: the Cisco snic; the advansys driver has
 been rewritten to get rid of the warning about converting it to the
 DMA API, the tape statistics patch got in and finally, there's a
 resuffle of SCSI header files to separate more cleanly initiator from
 target mode (and better share the common definitions).
