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