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.

Merge branch 'clocksource' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu into timers/core

Pull clocksource watchdog updates from Paul McKenney:

- Avoid accidental unstable marking of clocksources by rejecting
clocksource measurements where the source of the skew is the delay
reading reference clocksource itself. This change avoids many of the
current false positives caused by epic cache-thrashing workloads.

- Reduce the default clocksource_watchdog() retries to 2, thus offsetting
the increased overhead due to #1 above rereading the reference
clocksource.

rcutorture: Add CONFIG_PREEMPT_DYNAMIC=n to tiny scenarios

With CONFIG_PREEMPT_DYNAMIC=y, the kernel builds with CONFIG_PREEMPTION=y
because preemption can be enabled at runtime. This prevents any tests
of Tiny RCU or Tiny SRCU from running correctly. This commit therefore
explicitly sets CONFIG_PREEMPT_DYNAMIC=n for those scenarios.
