返回类型：int

参数：

类型参数名称
enum cpuhp_statestate
1555  当:state恒等于CPUHP_AP_ONLINE_DYN
1556  step等于cpuhp_hp_states加CPUHP_AP_ONLINE_DYN
1557  end等于CPUHP_AP_ONLINE_DYN_END
1558  退出
1559  当:state恒等于CPUHP_BP_PREPARE_DYN
1560  step等于cpuhp_hp_states加CPUHP_BP_PREPARE_DYN
1561  end等于CPUHP_BP_PREPARE_DYN_END
1562  退出
