	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).
