Ah, right! Hmm, it seems some more work to update it. but basically, we can do.
BTW, is there any other users who need to access the actual function entry (for
kallsyms case)?

If so, I guess it'd better to merge this version and replace kprobe's local
arch_deref_entry_point() with generic function_entry() macro.

Thank you,
