函数名称：To the best of our knowledge Windows compatible x86 hardware expects* the following on reboot:* 1) If the FADT has the ACPI reboot register flag set, try it* 2) If still alive, write to the keyboard controller* 3) If still alive, write to the ACPI reboot

函数原型：static void native_machine_emergency_restart(void)

返回类型：void

参数：无
