These patches are based on Martin Petersen's 6.8/scsi-queue tree
  https://git.kernel.org/pub/scm/linux/kernel/git/mkp/scsi.git
  6.8/scsi-queue

The only functional change to smartpqi is correction of a race condition
during a scan/rescan operation. The device->rescan flag can be updated
by multiple threads causing issues.

The other two patches add PCI-IDs for new controllers and change the
driver version.

This set of changes consists of:
* smartpqi-Add-new-controller-PCI-IDs
  No functional changes. Just adding in more device support.
* smartpqi: fix logical volume rescan race condition
  The driver has several threads that can contend for accessing
  a controller instance wide 'rescan' flag. In some rare cases
  a race condition can occur that bypasses a call to rescan for
  device changes. Some of these changes are; device removal, logical
  volume changes, and device adds. We basically added a spin-lock
  to protect the 'rescan' flag.
* smartpqi-change-driver-version-to-2.1.26-030
  No functional changes.
