Subject: [PATCH 1/4] sh: fix -Wmissing-include-dirs warnings for various platforms
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.
