This batch of changes is mostly clean ups and small bug fixes.
The only real feature that was added this release is from Namhyung Kim,
who introduced "set_graph_notrace" filter that lets you run the function
graph tracer and not trace particular functions and their call chain.
Tom Zanussi added some updates to the ftrace multibuffer tracing that
made it more consistent with the top level tracing.
One of the fixes for perf function tracing required an API change in
RCU; the addition of "rcu_is_watching()". As Paul McKenney is pushing
that change in this release too, he gave me a branch that included
all the changes to get that working, and I pulled that into my tree
in order to complete the perf function tracing fix.
tracing: Add rcu annotation for syscall trace descriptors
sparse complains about the enter/exit_sysycall_files[] variables being
dereferenced with rcu_dereference_sched(). The fields need to be
annotated with __rcu.
