The jump table can reference text found in an __exit section. Thus, instead of discarding it at build/link time, include EXIT_TEXT as part of __init and release it at system boot time.
Without this patch the link fails with:
`.exit.text' referenced in section `__jump_table' of xxx.o: defined in discarded section `.exit.text' of xxx.o
