Pull libata fixes from Tejun Heo:
 "I sat on them too long and it's quite a few this late, but nothing has
  a wide blast area. The changes are...

   - Fix corner cases in SG command handling.

   - Recent introduction of default powersaving mode config option
     exposed several devices with broken powersaving behaviors. A number
     of patches to update the blacklist accordingly.

   - Fix a kernel panic on SAS hotplug.

   - Other misc and device specific updates"
