Subject: [PATCH 0/4] sched/idle: Fix missing need_resched() checks after rcu_idle_enter() v2

The only code change in this v2 is the use of tif_need_resched() instead
of need_resched() on 3/4 (build issue reported on linux-next).

The rest is added Tested-by and Reviewed-by tags.

HEAD: c246718af0112c8624ec9c46a85bf0ef1562e050

Thanks,
