[PATCH] Always enable mmiotrace when building x86 kernels

[Hans de Goede]

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.
