Merge branch 'for-3.10-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata

Browse Source 
Pull libata changes from Tejun Heo:
 "Nothing too interesting.  PCI ID additions, some sata_rcar fixes and a
  fringe bug fix for DMADIR handling which shouldn't affect any device
  remotely modern."

* 'for-3.10-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata:
  sata_rcar: fix interrupt handling
  ahci: add an observed PCI ID for Marvell 88se9172 SATA controller
  sata_rcar: clear STOP bit in bmdma_start() method
  libata: make ata_exec_internal_sg honor DMADIR
  ata_piix: add PCI IDs for Intel BayTail
  libata: update "Maintained by:" tags
