Read my reply to the email that I forgot to add to the cover letter (but
mention in the last patch). Fixing kallsyms does not remove the place
holders in the available_filter_functions. This has nothing to do with
kallsyms. I need to remove the fentry/mcount references in the mcount_loc
section.

The kallsyms is a completely different issue.
