Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI fixes from James Bottomley:
"I'd like to say these were a set of regressions for the recent merge
window code. Unfortunately, they all predate the merge window code
(stable cc'd).
There are two fixes for data integrity (mostly only showing up on
module removal), an mvsas crash with expander attached SATA devices
which goes back to the dawn of the driver but is only just being
picked up as sas expanders become a standard item in low end server
hardware, an am53c974 one because the interrupt data isn't fully
initialised before the line is and a megaraid_sas one because it uses
smp_processor_id() to select MSI-X queues and that now triggers a
WARN_ON()"
* tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
mvsas: fix panic on expander attached SATA devices
am53c974: Fix crash during modprobe
megaraid_sas: use raw_smp_processor_id()
sd: Fix missing ATO tag check
sd: Unregister integrity profile
