Merge tag 'rcu.2023.08.21a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu

Pull RCU updates from Paul McKenney:

- Documentation updates

- Miscellaneous fixes, perhaps most notably simplifying
SRCU_NOTIFIER_INIT() as suggested

- RCU Tasks updates, most notably treating Tasks RCU callbacks as lazy
while still treating synchronous grace periods as urgent. Also fixes
one bug that restores the ability to apply debug-objects to RCU Tasks
and another that fixes a race condition that could result in
false-positive failures of the boot-time self-test code

- RCU-scalability performance-test updates, most notably adding the
ability to measure the RCU-Tasks's grace-period kthread's CPU
consumption. This proved quite useful for the RCU Tasks work

- Reference-acquisition/release performance-test updates, including a
fix for an uninitialized wait_queue_head_t

- Miscellaneous torture-test updates

- Torture-test scripting updates, including removal of the
non-longer-functional formal-verification scripts, test builds of
individual RCU Tasks flavors, better diagnostics for loss of
connectivity for distributed rcutorture tests, disabling of reboot
loops in qemu/KVM-based rcutorture testing, and passing of init
parameters to rcutorture's init program

Merge tag 'rcu.2022.01.09a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu

Pull RCU updates from Paul McKenney:

- Documentation updates, perhaps most notably Neil Brown's writeup of
the reference-counting analogy to RCU.

- Expedited grace-period cleanups.

- Remove CONFIG_RCU_FAST_NO_HZ due to lack of valid users. I have asked
around, posted a blog entry, and sent this series to LKML without
result.

- Miscellaneous fixes.

- RCU callback offloading updates, perhaps most notably Frederic
Weisbecker's updates allowing CPUs booted in the de-offloaded state
to be offloaded at runtime.

- nolibc fixes from Willy Tarreau and Anmar Faizi, but also including
Mark Brown's addition of gettid().

- RCU Tasks Trace fixes, including changes that increase the
scalability of call_rcu_tasks_trace() for the BPF folks (Martin Lau
and KP Singh).

- Various fixes including those from Wander Lairson Costa and Li
Zhijian.

- Fixes plus addition of tests for the increased call_rcu_tasks_trace()
scalability.
