HAVE_AOUT doesn't quite do the same thing as the recently removed ARCH_SUPPORTS_AOUT config option. That was set even on platforms where binfmt_aout isn't supported, although it's not entirely clear why. So it's best just to introduce a new symbol, handled consistently with other similar HAVE_xxx symbols; with a simple 'select' in the arch Kconfig.

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).
