While we make a 1:1 mapping (identity mapping) for all physical pages
we still need to use the MTRR's to ensure that the cachability attirbutes
we still need to use the MTRR's to ensure that the cachability attributes
for all memory regions is correct.
The basic idea is to use 2MB page table entries where ever possible. If
