3.8.13.27 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Thomas Jarosch <thomas.jarosch@intra2net.com>
commit 7c82126a94e69bbbac586f0249e7ef11e681246c upstream.
After a CPU upgrade while keeping the same mainboard, we faced "spurious interrupt" problems again.
It turned out that the new CPU also featured a new GPU with a different PCI ID.
Add this PCI ID to the quirk table. Probably all other Intel GPU PCI IDs are affected, too, but I don't want to add them without a test system.
See f67fd55fa96f ("PCI: Add quirk for still enabled interrupts on Intel Sandy Bridge GPUs") for some history.
