Have you at all followed the discussion about the people who asked for 
cross-CPU ordering? They wanted not timestamps at all, but global atomic 
counter updates. Which is very reasonable, if timestamps don't work (and 
jiffies certainly doesn't, especially in a NOHZ environment).

IOW, my whole argument is that what tracers want is _not_ the same thing 
as what "sched_clock()" wants.
