	This is needed when the host on which you run has a 2G/2G memory
	split, instead of the customary 3G/1G.

	Note that to enable such a host
	configuration, which makes sense only in some cases, you need special
	host patches.

	So, if you do not know what to do here, say 'N'.

	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).
