 +       We keep the static function tracing (!DYNAMIC_FTRACE) around
 +       in order to test the non static function tracing in the
 +       generic code, as other architectures still use it. But we
 +       only need to keep it around for x86_64. No need to keep it
 +       for x86_32. For x86_32, force DYNAMIC_FTRACE.
