Merge branch 'timers/nohz-irq-work-v7' of git://git.kernel.org/pub/scm/linux/kernel...

Pull nohz updates from Frederic Weisbecker:

 " This set moves the nohz kick, used to notify a full dynticks CPU when
   events require tick rescheduling, out of the scheduler tick to a
   dedicated IPI.

   This debloats a bit the scheduler IPI from off-topic work that was
   abusing that scheduler fast path for its convenient asynchronous
   properties. Now the nohz kick uses irq-work for its own needs.

   Of course this implied quite some background infrastructure rework,
   including:

     * Clean up some irq-work internals
     * Implement remote irq-work
     * Implement nohz kick on top of remote irq-work
     * Move full dynticks timer enqueue notification to new kick
     * Move multi-task notification to new kick
     * Remove unecessary barriers on multi-task notification
 "
