    Reasonable. As long as what the quirk is to avoid errata and
    chipset specific issues I don't have a problem with it.

    I figure the quirk should be a separate patch though.

    My concern is that the general rule that always enabling HT MSI
    mapping capabilities is reasonable. Even if there are some
    specific exceptions where we don't want to do that.

    I want code that requires the smallest list of chipset
    exceptions that we can make.
