In arch/um there's a lot of code that is copied from their original
arch (but out of sync) and contains code blocks that are either dead
because these options disappearedd or because the arch/x86 Kconfig
stuff doesn't reach arch/um.
X86_OOSTORE is a bit tricky because it's in itself seemingly available
on arch/um but depends on MTRR which isn't in arch/um.
