Expand description

Support for the Page Attribute Table (PAT) feature on x86.

PAT replaces the legacy Memory Type Range Registers (MTRRs) on x86. PAT allows the system to assign memory types, i.e., specify their caching behavior, to regions of “linear” (virtual) addresses. This is in contrast to MTRRs, which operate on regions of physical addresses.
