Subject: [GIT PULL] SCSI fixes for the 4.0+ merge window

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's 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().

The patch is available here:

git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git scsi-misc

The Short Changelog is

Christoph Hellwig (1):
      megaraid_sas: use raw_smp_processor_id()

Hannes Reinecke (1):
      am53c974: Fix crash during modprobe

James Bottomley (1):
      mvsas: fix panic on expander attached SATA devices

Martin K. Petersen (2):
      sd: Fix missing ATO tag check
      sd: Unregister integrity profile
