From ddb45306018f6be5661c4f66c12ffbbecf9bcb9f Mon Sep 17 00:00:00 2001 From: Jason Baron Date: Wed, 3 Aug 2016 13:46:33 -0700 Subject: [PATCH] arm: jump label may reference text in __exit 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.
