cpuhp_setup_state() invokes the startup callback on all online cpus with the proper protection, so we can remove the cpu hotplug protection from the init function and the creation of the per cpu files for online cpus in smp_add_present_cpu(). smp_add_present_cpu() is called also called from __smp_rescan_cpus(), but this callpath never adds an online cpu, it merily adds newly present cpus, so the creation of the cpu files is not required.
