[merged] init-kconfig-make-compile_test-depend-on-has_iomem.patch removed from -mm tree

[akpm]

The patch titled
     Subject: init/Kconfig: make COMPILE_TEST depend on HAS_IOMEM
has been removed from the -mm tree.  Its filename was
     init-kconfig-make-compile_test-depend-on-has_iomem.patch

This patch was dropped because it was merged into mainline or a subsystem tree

From: Masahiro Yamada <masahiroy@kernel.org>
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'.
