It appears to be some sort of header inclusion order issue?

The problem is that kernel/module/internal.h is not prepared to be
included when CONFIG_MODULES=n. It seems to me that the best solution
would be to move find_kallsyms_symbol_value into include/linux/module.h
and include that from kernel/bpf/verifier.c (instead of internal.h).

I'll post a fix tomorrow unless someone has objections or a better idea.

Viktor
