 - 2/7 ftrace, perf: Add open/close tracepoint perf registration actions
 - 3/7 ftrace, perf: Add add/del tracepoint perf registration actions
 - 4/7 ftrace: Add FTRACE_ENTRY_REG macro to allow event registration
 - 5/7 ftrace, perf: Add support to use function tracepoint in perf
 - 6/7 ftrace: Allow to specify filter field type for ftrace events
 - 7/7 ftrace, perf: Add filter support for function trace event

v9 changes:

    CONFIG_FUNCTION_TRACER, CONFIG_DYNAMIC_FTRACE

thanks,
jirka
