After the stack changes we can finally use -mbackchain and have a

I asssume this hunk should go into the next patch instead?
Or should the change to handle_pgm_int() from the next patch go into this
patch here instead?
Otherwise you have an unused static function here and the compiler might
complain about it (when bisecting later).
