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

From: Frederic Weisbecker
Date: Tue Feb 20 2018 - 23:17:46 EST


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
