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.
