As I said before, some configurations don't make sense.

If such a configuration can be achieved using allmod/yesconfig it has to be

Chen's fixes seem reasonable as not all architectures support iomem.

Maybe we should stub out ioremap() and friends when COMPILE_TEST is enabled to avoid these linker errors. That's in my opinion better than turning most of the 'depends on COMPILE_TEST' into 'depends on COMPILE_TEST && HAS_IOMEM'. The issue comes up quite a lot and it is often overlooked when adding a driver that can be build when COMPILE_TEST is enabled.
