+Subject: init/Kconfig: make COMPILE_TEST depend on HAS_IOMEM
+
+From: Masahiro Yamada <masahiroy@kernel.org>
+
+commit ea29b20a828511de3348334e529a3d046a180416 upstream.
+
+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'.

+Subject: init/Kconfig: make COMPILE_TEST depend on !S390
+
+From: Heiko Carstens <hca@linux.ibm.com>
+
+commit 334ef6ed06fa1a54e35296b77b693bcf6d63ee9e upstream.
+
+While allmodconfig and allyesconfig build for s390 there are also
+various bots running compile tests with randconfig, where PCI is
+disabled. This reveals that a lot of drivers should actually depend on
+HAS_IOMEM.
+Adding this to each device driver would be a never ending story,
+therefore just disable COMPILE_TEST for s390.
+
+The reasoning is more or less the same as described in
+commit bc083a64b6c0 ("init/Kconfig: make COMPILE_TEST depend on !UML").
