The 0day bot reports a lot of warnings (or errors due to CONFIG_WERROR) like this: cc1: error: arch/sh/include/mach-hp6xx: No such file or directory [-Werror=missing-include-dirs] Indeed, arch/sh/include/mach-hp6xx does not exist. -Wmissing-include-dirs is W=1 warning, but it may be annoying when CONFIG_BTRFS_FS is enabled because fs/btrfs/Makefile unconditionally adds this warning option. arch/sh/Makefile defines machdir-y for two purposes: - Build platform code in arch/sh/boards/mach-*/ - Add arch/sh/include/mach-*/ to the header search path For the latter, some platforms use arch/sh/include/mach-common/ instead of having its own arch/sh/include/mach-*/. Drop unneeded machdir-y to not include non-existing include directory. To build arch/sh/boards/mach-*/, use the standard obj-y syntax in arch/sh/boards/Makefile.
