    Ack.

    I think architectures that have virtual caches might want to think
    about this patch a bit more, but on the whole I can't argue against
    the "it's badly documented and misused".

    No sane architecture will care, since dcache will be coherent (there
    are more issues on the I$ side, but that's a different issue)
