Hi all,

After merging the tip tree, yesterday's linux-next build (x86_64 allnoconfig)

produced this warning:

kernel/cpu.c:129:13: warning: 'cpuhp_is_ap_state' defined but not used [-Wunused-function]

  static bool cpuhp_is_ap_state(enum cpuhp_state state)
              ^~~~~~~~~~~~~~~~~

Yes, Jiangshan has replaced it with cpuhp_hp_states. So it is obsolete,
it should be removed.

I made a mistake, It also be called by cpuhp_thread_fun() and
cpuhp_issue_call(), let me have a look carefully.

Thanks,
        dou.

Thanks,
