Just to be clear what I'm looking for here: Special casing UV systems is theoretically OK. What I don't like is doing that in using GB pages or not. It would be much nicer to have specific, precise information about what UV needs done. For instance, do we know where the special address range is? Is it fixed? If so, I'd much rather have code that says: "Whoa, don't map this range with *any* identity map page tables" versus something targeted specifically at gbpages.
