Subject: init/Kconfig: make COMPILE_TEST depend on HAS_IOMEM
I read the commit log of the following two:
- bc083a64b6c0 ("init/Kconfig: make COMPILE_TEST depend on !UML")
- 334ef6ed06fa ("init/Kconfig: make COMPILE_TEST depend on !S390")
Both are talking about HAS_IOMEM dependency missing in many drivers.
So, 'depends on HAS_IOMEM' seems the direct, sensible solution to me.
This does not change the behavior of UML. UML still cannot enable
COMPILE_TEST because it does not provide HAS_IOMEM.
The current dependency for S390 is too strong. Under the condition of
CONFIG_PCI=y, S390 provides HAS_IOMEM, hence can enable COMPILE_TEST.
I also removed the meaningless 'default n'.
