Subject: [GIT PULL] SCSI fixes for 3.5-rc2

This is a couple of minor fixes, one for a preempt warning in the
mpt2sas driver and one is a config failure with the new sd async domain.

The patch is available here:

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

The short changelog is:

James Bottomley (1):
      Fix sd_probe_domain config problem

nagalakshmi.nandigama@....com (1):
      mpt2sas: Fix unsafe using smp_processor_id() in preemptible
