Any __exitcall() and built-in module_exit() handler is marked as __used, which leads to the code being included in the object file and later discarded at link time. As far as I can tell, this was originally added at the same time as initcalls were marked the same way, to prevent them from getting dropped with gcc-3.4, but it was never actaully necessary to keep exit functions around. Mark them as __maybe_unused instead, which lets the compiler treat the exitcalls as entirely unused, and make better decisions about dropping specializing static functions called from these.
