Subject: [PATCH memory-model 0/31] LKMM scripting updates for v6.4

Hello!

This series provides scripting updates that ease validating
the effects of changes to LKMM:

1.	tools/memory-model:  Document locking corner cases.

2.	tools/memory-model: Make judgelitmus.sh note timeouts.

3.	tools/memory-model: Make cmplitmushist.sh note timeouts.

4.	tools/memory-model: Make judgelitmus.sh identify bad macros.

5.	tools/memory-model: Make judgelitmus.sh detect hard deadlocks.

6.	tools/memory-model: Fix paulmck email address on pre-existing
	scripts.

7.	tools/memory-model: Update parseargs.sh for hardware verification.

8.	tools/memory-model: Make judgelitmus.sh handle hardware
	verifications.

9.	tools/memory-model: Add simpletest.sh to check locking, RCU,
	and SRCU.

10.	tools/memory-model: Fix checkalllitmus.sh comment.

11.	tools/memory-model: Hardware checking for check{,all}litmus.sh.

12.	tools/memory-model: Make judgelitmus.sh ransack .litmus.out files.

13.	tools/memory-model: Split runlitmus.sh out of checklitmus.sh.

14.	tools/memory-model: Make runlitmus.sh generate .litmus.out
	for --hw.

15.	tools/memory-model: Move from .AArch64.litmus.out to
	.litmus.AArch.out.

16.	tools/memory-model: Keep assembly-language litmus tests.

17.	tools/memory-model: Allow herd to deduce CPU type.

18.	tools/memory-model: Make runlitmus.sh check for jingle errors.

19.	tools/memory-model: Add -v flag to jingle7 runs.

20.	tools/memory-model: Implement --hw support for checkghlitmus.sh.

21.	tools/memory-model: Fix scripting --jobs argument.

22.	tools/memory-model: Make checkghlitmus.sh use mselect7.

23.	tools/memory-model: Make history-check scripts use mselect7.

24.	tools/memory-model:  Add "--" to parseargs.sh for additional
	arguments.

25.	tools/memory-model: Repair parseargs.sh header comment.

26.	tools/memory-model: Add checktheselitmus.sh to run specified
	litmus tests.

27.	tools/memory-model: Add data-race capabilities to judgelitmus.sh.

28.	tools/memory-model: Make judgelitmus.sh handle scripted Result:
	tag.

29.	tools/memory-model: Use "-unroll 0" to keep --hw runs finite.

30.	tools/memory-model: Use "grep -E" instead of "egrep", courtesy
	of Tiezhu Yang.

31.	tools/memory-model: Document LKMM test procedure.

						Thanx, Paul
