  Log:
  CPU time accounting speedup (step 2)
  
  Keep accounting time (in per-cpu) cputicks and the statistics counts
  in the thread and summarize into struct proc when at context switch.
  
  Don't reach across CPUs in calcru().
  
  Add code to calibrate the top speed of cpu_tickrate() for variable
  cpu_tick hardware (like TSC on power managed machines).
  
  Don't enforce monotonicity (at least for now) in calcru.  While the
  calibrated cpu_tickrate ramps up it may not be true.
  
  Use 27MHz counter on i386/Geode.
  
  Use TSC on amd64 & i386 if present.
  
  Use tick counter on sparc64
