IIRC this new patch effectively reverts back to the original behavior that
I implemented back at the dawn of time. I.e. just always mark the whole
page "not present" and don't try to mess with UC mappings to allow
partial (but non-speculative) access to the not-poisoned parts of the
page.

If that is the case ... then Acked-by: Tony Luck <tony.luck@xxxxxxxxx>

If I've misunderstood ... then please explain what it is doing.

Thanks
