Merge tag 'for-linus' of git://git./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
