x64 Virtual Memory Management Services in the form of an IA-32 driver.
Used to establish a 1:1 Virtual to Physical Mapping that is required to
enter Long Mode (x64 64-bit mode).
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 attributes
for all memory regions is correct.
The basic idea is to use 2MB page table entries where ever possible. If
more granularity of cachability is required then 4K page tables are used.
