Subject[PATCH v3 3/7] sparc: support static_key usage in non-module __exit sections
Date
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
