From ea29b20a828511de3348334e529a3d046a180416 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Fri, 12 Mar 2021 21:07:08 -0800 Subject: [PATCH] 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'.
