[PATCH tip/core/rcu 0/26] Torture-test updates for v5.14

[Paul E. McKenney]

Hello!

This series provides torture-test updates:

1.	Fix remaining erroneous torture.sh instance of $*.

2.	Add "scenarios" option to kvm.sh --dryrun parameter.

3.	Make kvm-again.sh use "scenarios" rather than "batches" file.

4.	Allow CPU hotplug to be enabled.

5.	Allow CPU hotplug to be enabled.

6.	Add kvm-remote.sh script for distributed rcutorture test runs.

7.	Add acqrel, lock, and lock-irq.

8.	Abstract read-lock-held checks.

9.	Fix grace-period rate output.

10.	Abstract end-of-run summary.

11.	Make kvm.sh use abstracted kvm-end-run-stats.sh.

12.	Make the build machine control N in "make -jN".

13.	Make kvm-find-errors.sh account for kvm-remote.sh.

14.	Judge RCU priority boosting on grace periods, not callbacks.

15.	Correctly fetch number of CPUs for non-English languages,
	courtesy of Frederic Weisbecker.

16.	Set kvm.sh language to English.

17.	Delay-based false positives for RCU priority boosting tests.

18.	Consolidate rcu_torture_boost() timing and statistics.

19.	Make rcu_torture_boost_failed() check for GP end.

20.	Add BUSTED-BOOST to test RCU priority boosting tests.

21.	Forgive RCU boost failures when CPUs don't pass through QS.

22.	Don't count CPU-stalled time against priority boosting.

23.	Make kvm-remote.sh account for network failure in pathname checks.

24.	Don't cap remote runs by build-system number of CPUs.

25.	Move mem_dump_obj() tests into separate function.

26.	Don't penalize priority boosting when there is nothing to boost.

						Thanx, Paul
