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