| 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). |
