Xen imposes a particular PAT layout on all paravirtual guests which
does not match the layout Linux would like to use.

Force PAT to be disabled until this is resolved.

No, this can be done via CPUID, which is paravirtualized already.

Stomp the PAT feature flag? Yes, that's a better idea.

Thanks,
