Hi Kui-Feng,

First bad commit (maybe != root cause):

tree:   https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git master
head:   11afac187274a6177a7ac82997f8691c0f469e41
commit: e9bbda13a7b876451285ab15fb600b809e5e2290 [8264/11963] selftests/bpf: Test case for lacking CFI stub functions.

All errors (new ones prefixed by >>, old ones prefixed by <<):

You may get many unresolved symbol errors.
You can set KBUILD_MODPOST_WARN=1 to turn errors into warning
