    The rationale is that a panic will likely be reported as a a bug and
    this lets us know that such CPUs exist, which we may otherwise not
    hear about.
    The user may bypass the panic by altering the command line.

    To avoid doing the panic, we could define an artificial "CX8_XMM"
    flag, set it if CX8 && XMM and use that in the alternatives code in
    the previous patch; this is a bit more intrusive.

    We already manually set the CX8 flag on VIA CPUs that mistakenly not
    report it, so that shouldn't be a problem.
