Merge tag 'rcu.2022.03.13a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu

Pull RCU updates from Paul McKenney:

- Fix idle detection (Neeraj Upadhyay) and missing access marking
detected by KCSAN.

- Reduce coupling between rcu_barrier() and CPU-hotplug operations, so
that rcu_barrier() no longer needs to do cpus_read_lock(). This may
also someday allow system boot to bring CPUs online concurrently.

- Enable more aggressive movement to per-CPU queueing when reacting to
excessive lock contention due to workloads placing heavy update-side
stress on RCU tasks.

- Improvements to RCU priority boosting, including changes from Neeraj
Upadhyay, Zqiang, and Alison Chaiken.

- Various fixes improving test robustness and debug information.

- Add tests for SRCU size transitions, further compress torture.sh
build products, and improve debug output.

- Miscellaneous fixes.

rcutorture: Test SRCU size transitions

Thie commit adds kernel boot parameters to the SRCU-N and SRCU-P
rcutorture scenarios to cause SRCU-N to test contention-based resizing
and SRCU-P to test init_srcu_struct()-time resizing. Note that this
also tests never-resizing because the contention-based resizing normally
takes some minutes to make the shift.

Merge branch 'core-rcu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull RCU updates from Ingo Molnar:
"The biggest change in this cycle is the conclusion of the big
'simplify RCU to two primary flavors' consolidation work - i.e.
there's a single RCU flavor for any kernel variant (PREEMPT and
!PREEMPT):

- Consolidate the RCU-bh, RCU-preempt, and RCU-sched flavors into a
single flavor similar to RCU-sched in !PREEMPT kernels and into a
single flavor similar to RCU-preempt (but also waiting on
preempt-disabled sequences of code) in PREEMPT kernels.

This branch also includes a refactoring of
rcu_{nmi,irq}_{enter,exit}() from Byungchul Park.

- Now that there is only one RCU flavor in any given running kernel,
the many "rsp" pointers are no longer required, and this cleanup
series removes them.

- This branch carries out additional cleanups made possible by the
RCU flavor consolidation, including inlining now-trivial
functions, updating comments and definitions, and removing
now-unneeded rcutorture scenarios.

- Now that there is only one flavor of RCU in any running kernel,
there is also only on rcu_data structure per CPU. This means that
the rcu_dynticks structure can be merged into the rcu_data
structure, a task taken on by this branch. This branch also
contains a -rt-related fix from Mike Galbraith.

There were also other updates:

- Documentation updates, including some good-eye catches from Joel
Fernandes.

- SRCU updates, most notably changes enabling call_srcu() to be
invoked very early in the boot sequence.

- Torture-test updates, including some preliminary work towards
making rcutorture better able to find problems that result in
insufficient grace-period forward progress.

- Initial changes to RCU to better promote forward progress of grace
periods, including fixing a bug found by Marius Hillenbrand and
David Woodhouse, with the fix suggested by Peter Zijlstra"
