sparc: support static_key usage in non-module __exit sections

mirror of https://github.com/linux-apfs/linux-apfs.git synced 2026-05-01 15:00:59 -07:00

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
