Subject[PATCH 0/6] isolation: 1Hz residual tick offloading v5
Date
This series should address most reviews from Peterz in v4:

* Check that the remote tick doesn't come way too late. For that we
track the last time we called update_curr() with checking
tsk->se.exec_start which doesn't only account for ticks but also queue
and dequeue events.

* Add comment to explain why we use HZ as a delay

* Feed changelog with explanation about correctness assumptions on
calling rq::task_tick() remotely.

The last element is to enforce unbound workqueues to queue a work on
a CPU of the same node when the enqueuer is outside the unbound mask.
This will be sorted out seperately.

Thanks,
