I'd prefer you to leave sched_clock() alone - I'm preparing a patch
series which replaces all sched_clock() implementations with something
that fully satisfies the scheduler requirements.
The first step of that is fixing the clocksource mess, which I recently
posted. I have a currently set of three possible further resolutions
which meet the scheduler requirements with varying overheads - some with
more and some with less overhead in the fast path than the current
cnt32_to_63 + multiply + do_div.
