As I said before, some configurations don't make sense.
If such a configuration can be achieved using allmod/yesconfig it has to be fixed.
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.
And what should this stub do?
Except calling BUG()...
return NULL;
It's for compile testing, it's not meant to work at runtime.
