SCSI misc on 20161213

Browse source 
This update includes the usual round of major driver updates (ncr5380,
 lpfc, hisi_sas, megaraid_sas, ufs, ibmvscsis, mpt3sas).  There's also
 an assortment of minor fixes, mostly in error legs or other not very
 user visible stuff.  The major change is the pci_alloc_irq_vectors
 replacement for the old pci_msix_.. calls; this effectively makes IRQ
 mapping generic for the drivers and allows blk_mq to use the
 information.
