Subject: [PATCH rcu 0/5] Callback-offloading (NOCB) updates for v5.19

Hello!

This series applies some simplifications to RCU's callback-offloading
code:

1.	Remove rcu_is_nocb_cpu(), courtesy of Frederic Weisbecker.

2.	Move rcu_nocb_is_setup to rcu_state, courtesy of Frederic
	Weisbecker.

3.	Assume rcu_init() is called before smp, courtesy of Frederic
	Weisbecker.

4.	Initialize boost kthread only for boot node prior SMP
	initialization, courtesy of Frederic Weisbecker.

5.	Initialize nocb kthreads only for boot CPU prior SMP
	initialization, courtesy of Frederic Weisbecker.

						Thanx, Paul
