22 help
23 This is needed when the host on which you run has a 2G/2G memory
24 split, instead of the customary 3G/1G.
26 Note that to enable such a host
27 configuration, which makes sense only in some cases, you need special
28 host patches.
30 So, if you do not know what to do here, say 'N'.

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