Until recently, if KBUILD_DEFCONFIG was not set by the arch Makefile, the default path arch/*/defconfig was used. The last users of the default are gone by the following commits: - Commitf3e20ad67b("s390: move arch/s390/defconfig to arch/s390/configs/defconfig") - Commit986a13769c("alpha: move arch/alpha/defconfig to arch/alpha/configs/defconfig") Let's set arch/*/configs/defconfig as a new default. This saves KBUILD_DEFCONFIG for some architectures. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Acked-by: Catalin Marinas <catalin.marinas@arm.com>
