Geert Uytterhoeven 7fa38e7e9e um: reinstate kernel version in generated .config
Commit 0954828fcb ("kconfig: replace KERNELVERSION usage by the
mainmenu's prompt") made the kernel version disappear from the generated
.config file when configuring for UML.  As UML's Kconfig doesn't have a
mainmenu, kconfig falls back to the default string "Linux Kernel
Configuration".

Add a suitable mainmenu to the main UML Kconfig file to fix this.

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).
