Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev 

Pull libata updates from Jeff Garzik:

 1) AHCI regression fix.  A recent "make driver conform to spec" change
    broke on deployed hardware.  Make new behavior optional, rather than
    default, turning it on only for specific embedded platforms that
    need this.

    Everybody else runs in the famous "non conformant but working" mode.

 2) pata_cmd64x, pata_legacy cleanups

 3) new Intel SATA PCI IDs

 4) misc minor vendor feature additions

* tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev:
  pata_cmd64x: implement sff_irq_check() method

  pata_cmd64x: use interrupt status from MRDMODE register
  pata_cmd64x: turn string of *if* statements into *switch*
  drivers/ata/pata_mpc52xx.c: clean up error handling code
  ahci_platform: add STRICT_AHCI platform type
  ahci: move AHCI_HFLAGS() macro to ahci.h
