If anyone has any objections, please let me know. ------------------ From: Youquan Song commit b55f84e2d527182e7c611d466cd0bb6ddce201de upstream. There is a quirk patch 5e5a4f5d5a08c9c504fe956391ac3dae2c66556d "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.
