Since there haven't been any updates let's re-try this again, ok? I had these commits in WIP.locking/atomics: 4b47cc154eed: locking/atomic/x86, asm-generic: Add comments for atomic instrumentation 35787d9d7ca4: locking/atomics, asm-generic: Add KASAN instrumentation to atomic operations 68c1ed1fdb0a: kasan: Allow kasan_check_read/write() to accept pointers to volatiles f1c3049f6729: locking/atomic/x86: Switch atomic.h to use atomic-instrumented.h d079eebb3958: locking/atomic: Add asm-generic/atomic-instrumented.h 007d185b4462: locking/atomic/x86: Use 's64 *' for 'old' argument of atomic64_try_cmpxchg() ba1c9f83f633: locking/atomic/x86: Un-macro-ify atomic ops implementation Thomas objected to the ugly instrumentation approach - so I'll keep only these two patches: 007d185b4462: locking/atomic/x86: Use 's64 *' for 'old' argument of atomic64_try_cmpxchg() ba1c9f83f633: locking/atomic/x86: Un-macro-ify atomic ops implementation because they appear to be uncontroversial. I've pushed these two out into tip:locking/core, future (re-)submissions should be based on that tree.
