Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi 

Pull SCSI updates from James Bottomley:
 "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"

This is a driver for the old NCR 53c80 series of SCSI controllers
on boards using PIO. Most boards such as the Trantor T130 fit this
category, along with a large number of ISA 8bit controllers shipped
for free with SCSI scanners. If you have a PAS16, T128 or DMX3191
you should select the specific driver for that card rather than
generic 5380 support.
It is explained in section 3.8 of the SCSI-HOWTO, available from
<http://www.tldp.org/docs.html#howto>. If it doesn't work out
of the box, you may have to change some settings in
<file:drivers/scsi/g_NCR5380.h>.
This is a driver for old ISA card SCSI controllers based on a
NCR 5380, 53C80, 53C400, 53C400A, or DTC 436 device.
Most boards such as the Trantor T130 fit this category, as do
