I don't know. It looks like an 'x' was deleted due to an editor
fat-finger or something. The original upstream patches were cc:d to
stable, so I think you would have got them that way (ie, I don't think I
sent them to you specifically). Is there an opportunity in your
workflow where this error could have crept in? The patches should have
been a pretty clean 'git cherry-pick' with no conflicts.
