This series applies to kernel/git/jejb/scsi.git for-next branch

This is a big patch series. Most of the changes have to do
with enabling alternate command submission paths for certain i/os
to bypass the Smart Array RAID firmware stack and submit i/o's
more directly to physical devices -- solid state disks --
for increased performance.
