<pre>This is a false positive caused by an upstream bug.
Feature got disabled in 4.14.0-rc5:
commit b483cf3bc249d7af706390efa63d6671e80d1c09
Author: Ingo Molnar <<a href="mailto:mingo@kernel.org">mingo@kernel.org</a>>
Date: Sat Oct 14 09:26:59 2017 +0200
locking/lockdep: Disable cross-release features for now
I also have a proposal for a fix
(<a href="https://patchwork.freedesktop.org/series/31937/">https://patchwork.freedesktop.org/series/31937/</a>) but overall it is now a
matter of keeping an eye on what will be happening with the feature in the
upstream, and progressing some flavour of a fix at a suitable time.</pre>
