Subject: [PATCH memory-model 0/14] Updates to the formal memory model
Hello!
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. Add a litmus test for full multi-copy atomicity.
2. Fix the name of the ISA2+pooncelock+pooncelock+pombonce litmus test.
3. Add Daniel Lustig as an LKMM reviewer, with focus on RISC-V,
courtesy of Palmer Dabbelt.
4. Update Korean translation to fix broken DMA vs. MMIO ordering
example, courtesy of SeongJae Park with edits suggested by
Byungchul Park.
5-6. Remove the now-obsolete ACCESS_ONCE() from recipes and the model
itself, courtesy of Mark Rutland.
7. Make regression-test scripts executable.
8. Describe atomic_set as a write operation, courtesy of Jonathan
Neuschäfer.
9. Add informal LKMM documentation to MAINTAINERS.
10. Use smp_mb() in wake_woken_function(), courtesy of Andrea Parri.
11. Clarify requirements for smp_mb__after_spinlock(), courtesy of
Andrea Parri.
12. Update wake_up() and friends' memory-barrier guarantees,
courtesy of Andrea Parri.
13. Fix "smb_wmb()" typo (should be "smp_wmb()"), courtesy of
Yauheni Kaliuta.
14. Rename litmus tests to comply to norm7, courtesy of Andrea Parri.
Thanx, Paul
