[intel/vol3]: Figure 4-11. Formats of CR3 and Paging-Structure Entries with 4-Level Paging and

5-Level Paging

[amd/vol2]: 5.3 Long-Mode Page Translation

Represents a general x86 page table entry.

Many of the operations below are dependent on whether the entry is terminal:

if a constructed entry is intended to be terminal that should be set first.
