Ugh. I am not personally a huge fan of this endless "fix up one at a time".

Just do a patch that removes current_text_addr() entirely and be done
with it, if that's what we want the end result to be.

Don't bother with these small "let's remove the remaining ones one by
one". Just get it over and done with.
