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_.
