    Impact: allow modules to add TRACE_EVENTS on load
    
    This patch adds the final hooks to allow modules to use the TRACE_EVENT
    macro. A notifier and a data structure are used to link the TRACE_EVENTs
    defined in the module to connect them with the ftrace event tracing system.
    
    It also adds the necessary automated clean ups to the trace events when a
    module is removed.
