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