workqueue: Convert to state machine callbacks

2016-07-14T07:34:43+00:00

Get rid of the prio ordering of the separate notifiers and use a proper state
callback pair.

sched/hotplug: Move migration CPU_DYING to sched_cpu_dying()

2016-05-06T12:58:25+00:00

sched/hotplug: Convert cpu_[in]active notifiers to state machine

2016-05-06T12:58:24+00:00

Now that we reduced everything into single notifiers, it's simple to move them
into the hotplug state machine space.

sched: Consolidate the notifier maze

2016-05-06T12:58:23+00:00

We can maintain the ordering of the scheduler cpu hotplug functionality nicely
in one notifer. Get rid of the maze.

rcu: Make CPU_DYING_IDLE an explicit call

2016-03-01T19:36:58+00:00

Make the RCU CPU_DYING_IDLE callback an explicit function call, so it gets
invoked at the proper place.

cpu/hotplug: Make wait for dead cpu completion based

2016-03-01T19:36:58+00:00

Kill the busy spinning on the control side and just wait for the hotplugged
cpu to tell that it reached the dead state.

cpu/hotplug: Convert to a state machine for the control processor

2016-03-01T19:36:54+00:00

Move the split out steps into a callback array and let the cpu_up/down
code iterate through the array functions. For now most of the
callbacks are asymmetric to resemble the current hotplug maze.

cpu/hotplug: Restructure FROZEN state handling

2016-03-01T19:36:53+00:00

There are only a few callbacks which really care about FROZEN
vs. !FROZEN. No need to have extra states for this.

Publish the frozen state in an extra variable which is updated under
the hotplug lock and let the users interested deal with it w/o
imposing that extra state checks on everyone.
