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.
