Thanks.

I try below build options, also can't reproduce this issue, so really don't know how to fix it.

make ARCH=arm64 distclean
make ARCH=arm64 allmodconfig
make -j8 ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- W=1 / make -j8 ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- W=2 / make -j8 ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- W=3

I saw many unrelated warnings...

Best Regards,
