[PATCH v3 5/7] arm: jump label may reference text in __exit

From: Jason Baron
Date: Wed Jul 06 2016 - 17:44:05 EST


The jump table can reference text found in an __exit section. Thus,
instead of discarding it at build time, include EXIT_TEXT as part
of __init and it will be released when the system boots.
