Sorry for this false-positive report.

Thanks for the info, we noticed that this patch has been merged into
linux-next, so we tested below commits:

b9f85101cad33 (tag: next-20221011, linux-next/master) Add linux-next specific files for 20221011
5d4aeffbf7092 kbuild: rebuild .vmlinux.export.o when its prerequisite is updated

They all passed the boot tests.
