    Let's see: we don't enable high by default because of old kexec-tools
    and some systems which do some funky reservations.

    But this patch kinda enables high by trying a couple more regions.

    So we don't really need this - we simply need to tell people to use high
    if it fails with KASLR, AFAICT.
