Currently CONFIG_HIGHMEM is broken on User Mode Linux.
I'm not sure if it worked ever.

This was used to allow UML to run with big amounts of memory.

What is "broken" about it?

Currently it does not even build.
This is very annoying when using "make randconfig".
And it was never stable.
See commit ce2d2aed:

[PATCH] uml: arch Kconfig menu cleanups
*) mark as "EXPERIMENTAL" various items that either aren't very stable or
that are actively crashing the setup of users which don't really need them
(i.e. HIGHMEM and 3-level pagetables on x86 - nobody needs either,
everybody reports "I'm using it and getting trouble").
*) move net/Kconfig near to the rest of network configurations, and
drivers/block/Kconfig near "Block layer" submenu.
*) it's useless and doesn't work well to force NETDEVICES on and to disable
the prompt like it's done. Better remove the attempt, and change that to a
simple "default y if UML".
*) drop the warning about "report problems about HPPFS" - it's redundant
anyway, as that's the usual procedure, and HPPFS users are especially
technical (i.e. they know reporting bugs is _good_).
