4.7-stable review patch. If anyone has any objections, please let me know. ------------------ From: Huacai Chen <chenhc@xxxxxxxxxx> commit 6dabf2b7a597a9613f0b8a2fcbe01e2a0a05c896 upstream. CPUFreq need min_delta_ticks/max_delta_ticks to be initialized, and this can be done by clockevents_config_and_register().
