I'm holding off on the rcu unsafe changes with perf and function tracing.
We'll still get bug splats with unsafe rcu usage, but we need to work
out a better solution than I was going to push for 3.12. It's too late
to get things smooth, thus we need to wait till 3.13 to get something
that is decent.
For now, root needs to be careful in how they trace functions with perf.
