Since MPX uses this emulation code and only cares about 64-bit addresses
(given the initial implemention from which I based my code), patches 1-18
need to be pulled together.
Perhaps I can send the v10 of patches 1-18 (or a v1 since is a new
series?). Patches 19-29 would constitute a series of improved emulation
plus UMIP code.
Does it make sense?
Thanks and BR,
Ricardo
