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
