[PATCH tip/core/rcu 0/5] Realtime-related RCU updates for v5.13

[Paul E. McKenney]

Hello!

These commits are related to RCU's realtime support, including better
testing preemption, improving testing of RCU priority boosting, and
ensuring that at least one rcutorture scenario tests use_softirq=0.

1.	Expedite deboost in case of deferred quiescent state.

2.	Make TREE03 use real-time tree.use_softirq setting.

3.	Fix testing of RCU priority boosting.

4.	Make rcu_read_unlock_special() expedite strict grace periods.

5.	Make jitter.sh handle large systems.

						Thanx, Paul
