Merge tag 'upstream-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev
Pull libata changes from Jeff Garzik:
"Minor libata updates, nothing notable.
1) Apply -- and then revert -- the FUA feature. Caused disk
corruption in linux-next, proving it cannot be turned on by
default.
Net effect to upstream tree: zero
2) New AHCI platform driver sata_highbank
3) Improve SCSI MODE SENSE handling; support MODE SELECT
4) AHCI: support aggressive device sleep (power mgmt)
5) sata_fsl: minor fix
6) pata_arasan: clk support"
* tag 'upstream-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev:
sata_mv: Fix warnings when no PCI
[libata] Makefile: Fix build error in sata_highbank
[libata] export ata_dev_set_feature()
libata-core: use ATA_LBA in ata_build_rw_tf()
ata/ahci_platform: Add clock framework support
pata_arasan: add Device Tree probing capability
pata_arasan: Add clk_{un}prepare() support
ata: add platform driver for Calxeda AHCI controller
sata_fsl: add workaround for data length mismatch on freescale V2 controller
ahci: implement aggressive SATA device sleep support
ata: define enum constants for IDENTIFY DEVICE
Revert "libata: enable SATA disk fua detection on default"
[libata] scsi: implement MODE SELECT command
[libata] scsi: support MODE SENSE request for changeable and default parameters
[libata] scsi: Remove unlikely() from FUA check
libata: enable SATA disk fua detection on default
