Actually, if I'm not mistaken, you only need to cover the HT hole with
one MTRR - the rest remains WB. And in order the mask bits to work, we
could make it a little bigger - we waste some memory but that's nothing
in comparison to the MCE.

You might need to talk to hw guys about the feasibility of this deal
though.

Thanks.
