Hi,
The modification of PF_IDLE semantics lately to fix a bug in rcutiny
eventually introduced new bugs in RCU-tasks. This v3 carries the
following changes:
* Use per_cpu_ptr() to correctly handle the remote CPU on [1/4] (Thanks Zqiang)
* Test is_idle_task() even for non-idle task (idle injection) [2/4] (Thanks Peterz)
* No need to use WRITE_ONCE() / READ_ONCE() on PF_IDLE modification [4/4]
(Thanks Peterz)

Thanks,
