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.
