Subject: [PATCH v2 6/6] tracing: Have filter accept "common_cpu" to be consistent

From: "Steven Rostedt (Google)" <rostedt@...dmis.org>

Make filtering consistent with histograms. As "cpu" can be a field of an
event, allow for "common_cpu" to keep it from being confused with the
"cpu" field of the event.
