This series contains updates to the Linux kernel's formal memory model in tools/memory-model, along with corresponding changes in documentation and Linux-kernel code. These patches are ready for inclusion into -tip. 1. Document litmus-test naming scheme. 2. Add extra ordering for locks and remove it for ordinary release/acquire, courtesy of Alan Stern. 3. Fix a README typo, courtesy of SeongJae Park. 4. Expand the list of LKMM limitations. 5. Replace smp_cond_acquire() with smp_cond_load_acquire(), courtesy of Andrea Parri.
