1826  sp等于cpuhp_get_step(state)
1829  BUG_ON(Sanity check for callbacks )
1831  如果非multi_instance则返回:负EINVAL
1834  cpus_read_lock()
1835  mutex_lock( & cpuhp_state_mutex)
1837  如果非invoke或非cpuhp_get_teardown_cb(state)则转到:remove
1844  遍历现有CPU(cpu)
1845  st等于per_cpu_ptr( & cpuhp_state, cpu)
1846  cpustate等于state
1848  如果cpustate大于等于state则Call the startup/teardown function for a step either on the AP or* on the current CPU.
