Subject: [PATCH 2/2] kernel, cpu: Remove bogus __ref annotations
Date: Sun, 19 Jul 2015 20:06:22 +0200	[thread overview]
Message-ID: <1437329182-4549-3-git-send-email-minipli@googlemail.com> (raw)
In-Reply-To: <1437329182-4549-1-git-send-email-minipli@googlemail.com>

cpu_chain lost its __cpuinitdata annotation long ago in commit
5c113fbeed7a ("fix cpu_chain section mismatch..."). This and the global
__cpuinit annotation drop in v3.11 vanished the need to mark all users,
including transitive ones, with the __ref annotation. Just get rid of it
to not wrongly hide section mismatches.
