Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull first round of SCSI updates from James Bottomley:
"The patch set is mostly driver updates (usf, zfcp, lpfc, mpt2sas,
megaraid_sas, bfa, ipr) and a few bug fixes. Also of note is that the
Buslogic driver has been rewritten to a better coding style and 64 bit
support added. We also removed the libsas limitation on 16 bytes for
the command size (currently no drivers make use of this)"
