[PATCH v5 1/5] cpufreq: powernv: Hot-plug safe the kworker thread

2016-01-21 Thread Shilpasri G Bhat
In the kworker_thread powernv_cpufreq_work_fn(), we can end up sending an IPI to a cpu going offline. This is a rare corner case which is fixed using {get/put}_online_cpus(). Along with this fix, this patch adds changes to do oneshot cpumask_{clear/and} operation. Suggested-by: Shreyas B Prabhu S
