Stephen pulls the -rcu "rcu/next" tag into -next, and does similarly for
a large number of other trees.  This serves to pre-test the commits that
are likely to show up in the upcoming merge window.  The pre-testing
includes the build testing that Stephen does directly and additional
testing that others do on the -next tree (for example, I occasionally
run rcutorture on it).

So these commits are in -next because I told Stephen to include them.

But if you would like, I would be happy to pull your series out of the
portion covered by rcu/next for the time being.
