- Three-level pagetables will let UML have more than 4G of physical
- memory. All the memory that can't be mapped directly will be treated
- as high memory.
- However, this it experimental on 32-bit architectures, so if unsure say
- N (on x86-64 it's automatically enabled, instead, as it's safe there).
