Re: [PATCH] Always enable mmiotrace when building x86 kernels

mmiotrace uses the ftrace framework for dynamic patching, so enabling it does not cause any performance impact. Having mmiotrace enabled is very useful for debugging nvidia / nouveau driver problems, as we often use mmiotraces for nouveau development / debugging.
