Commit Message

EXPORT_UNUSED_SYMBOL* is not actually used anywhere.  Remove the
unused functionality as we generally just remove unused code anyway.

Thanks for the cleanups. While we're here, I noticed that struct
symsearch is only used internally in kernel/module.c, so I don't think
it actually needs to be in include/linux/module.h. I don't see it used
anywhere else. We could move maybe that to kernel/module-internal.h.

I've added a patch to just move it directly into module.c.
