    There is a quirk patch 5e5a4f5d
    "ata_piix: make DVD Drive recognisable on systems with Intel Sandybridge
     chipsets(v2)" fixing the 4 ports IDE controller 32bit PIO mode.
    
    We've hit a problem with DVD not recognized on Haswell Desktop platform which
    includes Lynx Point 2-port SATA controller.
    
    This quirk patch disables 32bit PIO on this controller in IDE mode.
    
    v2: Change spelling error in statememnt pointed by Sergei Shtylyov.
    v3: Change comment statememnt and spliting line over 80 characters pointed by
        Libor Pechacek and also rebase the patch against 3.8-rc7 kernel.
