Ok, that was an old copy-paste. Will resubmit a revised version in a moment.

Yes, these are quite handy. I will also check if my previously spotted
performance issues with sched_clock are relieved with the latest
clocksource-related instrumentary in 'devel': maybe it wasn't all due
to evil busy-waiting on counter-to-bus synchronization. However, that
would probably be worth a separate small patch.
