    kernel - Fix panic() on AMD
    * The cpu_smp_stopped() function assumed that cpu_mwait_hints[] exists,
      but it might not (could be NULL).
    * Conditionalize to avoid insta-panicing all cpus all at the same time
      when one cpu tries to stop the others during a panic().  This fixes
      panics on AMD cpus.
