    I think it's better to put profile.c under CONFIG_PROFILING as
    _expected_, so CONFIG_PROFILING=n users won't get any overhead, immediate or
    not. That's what I'm going to do after test-booting bunch of kernels.

    Thus, enabling CONFIG_PROFILING option will buy you some overhead,
    again, as _expected_.
