Subject: [PATCH 0/2] rcu/ftrace: Add rcu_dereference_raw_notrace() and friends

Paul,

As you suggesed using the name "*_notrace", I updated my patch. There's
two patches now.

The first patch adds two new APIs to the RCU system.
 rcu_dereference_raw_notrace()
 hlist_for_each_entry_rcu_notrace()

I needed the second one as the function tracer uses that too and it
calls rcu_dereference_raw().

Is this acceptable for you? If so can you give me your acked-by, so that
I can push this up to Linus. Otherwise, the system locks up when doing
function tracing with too much RCU debug running.

Thanks,

-- Steve
