| 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). | |
