Subject: sparc: support static_key usage in non-module __exit sections
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
