  Fix a shutdown hang on some SMP systems.  The previous logic was to IPI all
  CPUs to make sure idle threads are evicted from the softc before returning
  from acpi_cpu_shutdown().  However, this is unnecessary since stop_cpus()
  handles this for itself and at this point it's possible that our IPI will be
  blocked (interrupts disabled).
