Subject: [PATCH 0/7] isolation: 1Hz residual tick offloading v7

This version addresses comments from Thomas:

* Convert tick_nohz_tick_stopped[_cpu]() to bool
* Add comments to each sched_class::task_tick() to make sure that datas
  are always fetched from rq and task passed in parameters to allow
  for remote ticks.
* Add reviewed-by tags

HEAD: b0d4913a0a39c717f354e40c1642264632e76960

Thanks,

Frederic Weisbecker (7):
      sched: Rename init_rq_hrtick to hrtick_rq_init
      nohz: Convert tick_nohz_tick_stopped() to bool
      nohz: Allow to check if remote CPU tick is stopped
      sched/isolation: Isolate workqueues when "nohz_full=" is set
      sched/isolation: Offload residual 1Hz scheduler tick
      sched/nohz: Remove the 1 Hz tick code
      sched/isolation: Update nohz documentation to explain tick offload
