I never understood why PTE entries waste 4 bits (WIMG)
for effectively very few valid combinations.
The only invalid combinations are WI=11 -- if you know of
a way to fit 12 combinations in fewer than 4 bits, let us
know :-)
Not all of those 12 are very useful, of course.

is yeah, if you don't mind being sloppy ;-)
