Subject: [PATCH RFC memory-model 0/7] Memory-model changes

Hello!

This series contains memory-model updates, not yet ready for inclusion:

1.	Add extra ordering for locks and remove it for ordinary
	release/acquire, courtesy of Alan Stern.  There is some
	remaining disagreement as to whether or not locks and ordinary
	release/acquire should have identical ordering properties.

2.	Replace smp_cond_acquire() with smp_cond_load_acquire(),
	courtesy of Andrea Parri.

3.	Expand the list of LKMM limitations.

4.	Fix a README typo, courtesy of SeongJae Park.

5.	Add scripts to check github litmus tests.

6.	Make scripts take "-j" abbreviation for "--jobs".

7.	Add .cfg and .cat files for s390, which is a not-for-mainline
	placeholder.

							Thanx, Paul
