- Dynamically allocate the cpu_softc[] array based on mp_maxid instead of
using a statically sized array that depended on 'options SMP'.
- Use mp_maxid rather than MAXCPU when walking all the CPUs looking for a
match.
- Always call smp_rendezvous() since UP kernels now provide this.
- Use mp_ncpus rather than cpu_ndevices when determining if we need to
disable C3 for SMP machines.
