Given KBUILD_IMAGE properly set in arch/*/Makefile, the default case should work in most scenarios. The only oddity is the naming of the copy destination, vmlinux-kbuild-${KERNELRELEASE}. Let's rename it to vmlinuz-${KERNELRELEASE} because the kernel is often compressed. Remove the warning to avoid unnecessary patch submissions when the default case suffices. Remove the x86 case, which is now equivalent to the default. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Reviewed-by: Nathan Chancellor <nathan@kernel.org>
