29 Three-level pagetables will let UML have more than 4G of physical
30 memory. All the memory that can't be mapped directly will be treated
31 as high memory.

Paolo 'Blaisorblade' Giarrussoce2d2ae2006-01-18 17:42:59 -080033 However, this it experimental on 32-bit architectures, so if unsure say
34 N (on x86-64 it's automatically enabled, instead, as it's safe there).
