[PATCH tip/core/rcu 0/6] Torture-test updates for v4.18

[Paul E. McKenney]

Hello!

This series contains torture-test updates:

1.	Add a script to edit output from failed runs.  Running this
	script takes your editor through the build errors and the various
	problems in the console output, for each such file, first showing
	a summary of the errors and then the full output.

2.	Code cleanup: Fold parse-torture.sh into parse-console.sh.

3.	Output end-of-test state onto the console for rcutorture, which
	can help locate cases where RCU is unnecessarily starting new
	grace periods.	Of course, if you are testing the default RCU
	flavor, the kernel probably asked for another grace period,
	but it can be useful for the other RCU flavors.

4.	Print the above end-of-test state in the rcutorture test
	summary provided by the rcutorture scripting.

5.	Abbreviate kvm.sh summary lines to avoid line wrap.

6.	Make kvm-find-errors.sh find build warnings.

							Thanx, Paul
