[PATCH 6/8] ftrace: use current CPU for function startup

[Steven Rostedt]

This is more of a clean up. Currently the function tracer initializes the
tracer with which ever CPU was last used for tracing. This value isn't
realy useful for function tracing, but at least it should be something other
than a random number.
