Merge tag 'locking-core-2021-06-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull locking updates from Ingo Molnar: - Core locking & atomics: - Convert all architectures to ARCH_ATOMIC: move every architecture to ARCH_ATOMIC, then get rid of ARCH_ATOMIC and all the transitory facilities and #ifdefs. Much reduction in complexity from that series: 63 files changed, 756 insertions(+), 4094 deletions(-) - Self-test enhancements - Futexes: - Add the new FUTEX_LOCK_PI2 ABI, which is a variant that doesn't set FLAGS_CLOCKRT (.e. uses CLOCK_MONOTONIC). [ The temptation to repurpose FUTEX_LOCK_PI's implicit setting of FLAGS_CLOCKRT & invert the flag's meaning to avoid having to introduce a new variant was resisted successfully. ] - Enhance futex self-tests - Lockdep: - Fix dependency path printouts - Optimize trace saving - Broaden & fix wait-context checks - Misc cleanups and fixes. * tag 'locking-core-2021-06-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (52 commits) locking/lockdep: Correct the description error for check_redundant() futex: Provide FUTEX_LOCK_PI2 to support clock selection futex: Prepare futex_lock_pi() for runtime clock selection lockdep/selftest: Remove wait-type RCU_CALLBACK tests lockdep/selftests: Fix selftests vs PROVE_RAW_LOCK_NESTING lockdep: Fix wait-type for empty stack locking/selftests: Add a selftest for check_irq_usage() lockding/lockdep: Avoid to find wrong lock dep path in check_irq_usage() locking/lockdep: Remove the unnecessary trace saving locking/lockdep: Fix the dep path printing for backwards BFS selftests: futex: Add futex compare requeue test selftests: futex: Add futex wait test seqlock: Remove trailing semicolon in macros locking/lockdep: Reduce LOCKDEP dependency list locking/lockdep,doc: Improve readability of the block matrix locking/atomics: atomic-instrumented: simplify ifdeffery locking/atomic: delete !ARCH_ATOMIC remnants locking/atomic: xtensa: move to ARCH_ATOMIC locking/atomic: sparc: move to ARCH_ATOMIC locking/atomic: sh: move to ARCH_ATOMIC ...
