Hi Stephen,

If you pull the latest kbuild for-next branch,
ARCH=arm64 will fail to build.

I will fix it soon.

For today's linux-next, you can patch
as follows.
(or, you can use the old branch)


diff --git a/Makefile b/Makefile
index f80c4ff93ec9..fbb4b95ae648 100644
--- a/Makefile
+++ b/Makefile

ifdef CONFIG_MODULES

Thanks.
