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.
