Rmoving __init cpu_hotplug_pm_sync_init() function after boot time and keep the static data defined in pm_notifier() is a normal behavior and normal usage in kernel. Same notifier registration usage function examples are ia64_mca_init() and msic_init() in mrst.c. There are quite a few other similar static data in __init functions usage examples in kernel source code.

So I would keep the same code in the patch.

I'll send an updated patch just to change the title typo.

Thanks.
