Subject: [PATCH RFC memory-model 0/21] LKMM updates for review

Hello!

This series contains LKMM updates:

1.	Make scripts be executable.

2.	Fix comment in MP+poonceonces.litmus, courtesy of Andrea Parri.

3.	Do not use "herd" to refer to "herd7", courtesy of Andrea Parri.

4.	Rewrite "KERNEL I/O BARRIER EFFECTS" section of memory-barriers.txt,
	courtesy of Will Deacon.

5-6.	Make LKMM scripts note timeouts instead of just saying that
	the validation was bad.

7.	Make LKMM scripts identify litmus-test typos and use of
	unsupported primitives instead of just saying that the validation
	was bad.

8.	Add support for synchronize_srcu_expedited().

9.	Make LKMM scripts detect unconditional deadlocks.

10-21.	Leverage Boqun Feng's C-to-assembly litmus-test-translation
	capability to allow verifying LKMM against hardware models
	for checkalllitmus.sh.  This is a work in progress.

							Thanx, Paul
