Much better :-)


But I'm puzzled by all the per-cpu-ish-ness of the stuff. Why would you
need to register things on a per-cpu basis?

Also:


+ list_for_each(pos, &per_cpu(cpuidle_devices_list, cpu)) {
+ temp_dev = container_of(pos, struct cpuidle_device,
+ percpu_list[cpu]);
+ if (dev == temp_dev) {
+ list_del(&temp_dev->percpu_list[cpu]);
+ cpuidle_remove_state_sysfs(temp_dev);
+ }
+ }

Looks buggy, either you want to break out of the loop on dev ==
temp_dev, or you want to use list_for_each_safe().
