RCU recursion? (code inspection)

[Rik van Riel]

Hi Paul,

While looking at synchronize_rcu(), I noticed that
synchronize_rcu_expedited() calls synchronize_sched_expedited(),
which can call synchronize_sched() when it is worried about
the counter wrapping, which can call synchronize_sched_expedited()

The code is sufficiently convoluted that I am unsure whether this
recursion can actually happen in practice, but I also did not spot
anything that would stop it.
