This doesn't look to be correct for the SMP case ... get_cycle() returns
the current CPU  %cr16, but these values are completely uncorrelated
between different CPUs (and may even move differently for cell based
systems).  Don't we either have to have some complex interpolator for
the per CPU variations of %cr16 or just not do %cr16 based cycle
interpretation on SMP systems?
