Merge branch 'for-3.11' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata

Pull libata updates from Tejun Heo:
 "Overview of changes:

   - The rest of maintainer email address updates.

   - Some core updates - more robust default behavior for port
     multipliers, better error reporting for SG_IO commands, and a way
     to better work around now ancient and probably pretty rare PATA ->
     SATA bridges with ATAPI devices.

   - sata_rcar stabilization.

   - Some hardware PCI ID additions and one-off low level driver
     updates."
