perf: Grab event_mutex before taking get_online_cpus() The event_mutex is a high level lock. It should never be taken under get_online_cpus() being held. Perf is the only user that does so. Move the taking of event_mutex outside of get_online_cpus() and this should solve the locking order. Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>
