+        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).
