2016-11-29thermal/intel_powerclamp: Convert to CPU hotplug stateSebastian Andrzej Siewior1-37/+36
This is a conversation to the new hotplug state machine with the difference that CPU_DEAD becomes CPU_PREDOWN. At the same time it makes the handling of the two states symmetrical. stop_power_clamp_worker() is called unconditionally and the controversial error message is removed. Finally, the hotplug state callbacks are removed after the powerclamping is stopped to avoid a potential race.

2016-11-29thermal/intel_powerclamp: Convert the kthread to kthread worker APIPetr Mladek1-122/+170
Kthreads are currently implemented as an infinite loop. Each has its own variant of checks for terminating, freezing, awakening. In many cases it is unclear to say in which state it is and sometimes it is done a wrong way. The plan is to convert kthreads into kthread_worker or workqueues API. It allows to split the functionality into separate operations. It helps to make a better structure. Also it defines a clean state where no locks are taken, IRQs blocked, the kthread might sleep or even be safely migrated. The kthread worker API is useful when we want to have a dedicated single thread for the work. It helps to make sure that it is available when needed. Also it allows a better control, e.g. define a scheduling priority. This patch converts the intel powerclamp kthreads into the kthread worker because they need to have a good control over the assigned CPUs. IMHO, the most natural way is to split one cycle into two works. First one does some balancing and let the CPU work normal way for some time. The second work checks what the CPU has done in the meantime and put it into C-state to reach the required idle time ratio. The delay between the two works is achieved by the delayed kthread work. The two works have to share some data that used to be local variables of the single kthread function. This is achieved by the new per-CPU struct kthread_worker_data. It might look as a complication. On the other hand, the long original kthread function was not nice either. The patch tries to avoid extra init and cleanup works. All the actions might be done outside the thread. They are moved to the functions that create or destroy the worker. Especially, I checked that the timers are assigned to the right CPU. The two works are queuing each other. It makes it a bit tricky to break it when we want to stop the worker. We use the global and per-worker "clamping" variables to make sure that the re-queuing eventually stops. We also cancel the works to make it faster. Note that the canceling is not reliable because the handling of the two variables and queuing is not synchronized via a lock. But it is not a big deal because it is just an optimization. The job is stopped faster than before in most cases.

udplite conflict is resolved by taking what 'net-next' did which removed the backlog receive method assignment, since it is no longer necessary.

2016-11-23devfreq_cooling: pass a pointer to devfreq in the power model callbacksJavi Merino1-2/+3
When the devfreq cooling device was designed, it was an oversight not to pass a pointer to the struct devfreq as the first parameters of the callbacks. The design patterns of the kernel suggest it for a good reason. By passing a pointer to struct devfreq, the driver can register one function that works with multiple devices. With the current implementation, a driver that can work with multiple devices has to create multiple copies of the same function with different parameters so that each devfreq_cooling_device can use the appropriate one. By passing a pointer to struct devfreq, the driver can identify which device it's referring to.
