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'.

help
|
|
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).
