AFAICT, NO_IOMEM only has a real purpose on UML these days. Could we take
a shortcut here and make COMPILE_TEST depend on !UML? Getting random stuff
to build on UML seems pointless to me and we special-case it in a number of
places already.

If UML is the only arch without io memory the dependency on !UML seems
reasonable to me. :-)

For me, if only uml left, I suggest to implement dummy functions within
uml instead of let CONFIG_UML appear in generic include directory. And
then remove all HAS_IOMEM and NO_IOMEM from kernel.

Erm, this is something completely different.
I thought we're focusing on COMPILE_TEST?
