    Nack to the string change. If you see this message, it's because your
    BIOS is BROKEN, and this brokenness has caused us to have to disable the
    VT-d feature completely. The fuckwits obviously never tested it even as
    far as booting a VT-d enabled OS on it even once¹.

    We _want_ people to think of it as hardware damage and return the board
    to the vendor, as unfit for the purpose for which it was sold.

    The rest of the series looks good though; thanks.

    I haven't applied the first patch, although it stands alone -- your
    other patches will depend on it and cause merge pain. Or do you want me
    to take the whole lot through the intel-iommu tree?

    ¹ Or maybe they did, but the OS didn't tell them clearly enough that it
    was broken.
