[PATCH tip/core/rcu 0/21] Torture-test updates for v5.3

[Paul E. McKenney]

Hello!

This series contains torture-test updates:

1.	Make jitter.sh select from only online CPUs, courtesy of
	Joel Fernandes.

2.	Add cpu0 to the set of CPUs to add jitter, courtesy of Joel
	Fernandes.

3.	Add cond_resched() to forward-progress free-up loop.

4.	Fix stutter_wait() return value and freelist checks.

5.	Allow inter-stutter interval to be specified.

6.	Make kvm-find-errors.sh and kvm-recheck.sh provide exit status.

7.	Provide rudimentary Makefile.

8.	Exempt tasks RCU from timely draining of grace periods.

9.	Exempt TREE01 from forward-progress testing.

10.	Give the scheduler a chance on PREEMPT && NO_HZ_FULL kernels.

11.	Halt forward-progress checks at end of run.

12.	Add trivial RCU implementation.

13.	Tweak kvm options, courtesy of Sebastian Andrzej Siewior.

14.	Capture qemu output.

15.	Add function graph-tracing cheat sheet.

16.	Run kernel build in source directory.

17.	Make --cpus override idleness calculations.

18.	Add --trust-make to suppress "make clean".

19.	Dump trace buffer for callback pipe drain failures.

20.	Suppress propagating trace_printk() warning.

21.	Upper case solves the case of the vanishing NULL pointer.

							Thanx, Paul
