Yes actually, and then the other day I saw Rabins patch adding
it to each and every machine. And I think Tim put out a similar
patch not too long ago.

Frederic Weisbecker then remarked that the sched_clock
prototype in sched.h already includes notrace. So it's
not strictly required the way I read it.

So with this in my back head I removed it.

But I guess I'll just re-add it for clarity, why not.

Yours,
