  Add a new routine kvm_getcptime(3) for fetching the equivalent of
  'kern.cp_time'.  For a live kernel it uses the sysctl.  For a crashdump,
  it first checks to see if the kernel has a 'cp_time' global symbol.  If
  it does, it uses that.  If that doesn't work, when it uses the recently
  added kvm_getmaxcpu(3) and kvm_getpcpu(3) routines to walk all the CPUs
  and sum up their counters.
