Sorry for the delay and thanks for taking a look.

I'll try to re-spin the patch set by the end of this week/early next
week.

Note that kallsyms_lookup() and module_address_lookup() is used
in many other situations.

we dereference only things that can be dereferenced.
so calling it on already dereferenced address, or address
that does need to be dereferenced is OK.

My concern is that it changes the behavior. It will suddenly return
another information for addresses that were not dereference before.

OK. I'd be really-really surprised to find out that anyone did
kallsyms_lookup()/module_address_lookup() on func descriptors,
but I understand your concerns. I'll try to keep everything
within vsprintf().
