    Subject[PATCH 3.10 06/46] PCI: Add new ID for Intel GPU "spurious interrupt" quirk
    Date
    3.10-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.
