Greetings,

I'm seeing $subject in master as of this merge window.  I don't see it
with my usual stripped down PREEMPT_VOLUNTARY or an enterprise-ish
NOPREEMPT config, but do see it with the attached, derived from my
enterprise-ish PREEMPT_RT config after running make oldconfig on it,
and reproducing the warning in virgin source.

	-Mike

Thanks, looks like an objtool bug.  Will fix.
