Subject: [PATCH tip/core/rcu 0/23] Torture-test updates for v5.9

Hello!

This series provides torture-test updates:

1.	 Remove qemu dependency on EFI firmware.

2.	Add script to smoke-test commits in a branch.

3.	Use true and false to assign to bool variables, courtesy of Zou Wei.

4.	Add races with task-exit processing.

5.	Set configfile variable to current scenario.

6.	Handle non-statistic bang-string error messages.

7.	NULL rcu_torture_current earlier in cleanup code.

8.	Remove whitespace from identify_qemu_vcpus output.

9.	Add --allcpus argument to the kvm.sh script.

10.	rcu/rcutorture: Replace 0 with false, courtesy of Jules Irenge.

11.	Create qemu-cmd in --buildonly runs.

12.	Add a stop-run capability.

13.	Abstract out console-log error detection.

14.	Check for unwatched readers.

15.	Pass --kmake-arg to all make invocations, courtesy of Marco Elver.

16.	Correctly summarize build-only runs.

17.	Improve diagnostic for KCSAN-incapable compilers.

18.	Add more tracing crib notes to kvm.sh.

19.	Add kvm-tranform.sh script for qemu-cmd files.

20.	Dump ftrace at shutdown only if requested.

21.	Avoid duplicate specification of qemu command.

22.	Remove obsolete "cd $KVM".

23.	Remove KCSAN stubs.

							Thanx, Paul
