I strongly agree. We've got a working cached SMM, from Stefan, so we
know that one can cache SMM. For the counterargument that SMM can not
be cached, we have a hint from someone that someone else had trouble
-- and we have no code to inspect -- sorry, that's not strong enough
evidence for me to accept that we need another change to the MTRR
code.
I would prefer that we take Stefan's code as-is.
