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"
