 Page Table Management

"Architectures that manage their Memory Management Unit (MMU) differently are expected to emulate the three-level page tables. For example, on the x86 without PAE enabled, only two page table levels are available. The Page Middle Directory (PMD) is defined to be of size 1 and "folds back" directly onto the Page Global Directory (PGD), which is optimized out at compile time."
