For this late in the game, we need to play it safe.

I got rid of my tracepoint patch and moved trace_init() to after
rcu_init(), which I think is good enough for Thomas. Thomas?

I'll start testing that now.

Later, if you could add a rcu_init() version that lets us call
call_rcu_sched() just after mm_init() then we could move trace_init()
up a bit more.
