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."
* 'for-3.11' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata: (22 commits)
AHCI: use ATA_BUSY

ahci: remove pmp link online check in FBS EH
sata highbank: add bit-banged SGPIO driver support
ahci: make ahci_transmit_led_message into a function pointer
sata_rcar: fix compilation warning in sata_rcar_thaw()
sata_highbank: increase retry count but shorten duration for Calxeda controller
ata: use pci_get_drvdata()
ipr: qc_fill_rtf() method should not store alternate status register
sata_rcar: add 'base' local variable to some functions
sata_rcar: correct 'sata_rcar_sht'
sata_rcar: kill superfluous code in sata_rcar_bmdma_fill_sg()
libata: do not limit R-Car SATA driver to shmobile
