|  | 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). |
