Merge branch 'locking/urgent' into locking/core (2021-12-18 10:57:03 +0100)
----------------------------------------------------------------
Peter Zijlstra says:
"Lots of cleanups and preparation; highlights:
- futex: Cleanup and remove runtime futex_cmpxchg detection
- rtmutex: Some fixes for the PREEMPT_RT locking infrastructure
- kcsan: Share owner_on_cpu() between mutex,rtmutex and rwsem and
annotate the racy owner->on_cpu access *once*.
- atomic64: Dead-Code-Elemination"
----------------------------------------------------------------
Arnd Bergmann (4):
futex: Ensure futex_atomic_cmpxchg_inatomic() is present
futex: Remove futex_cmpxchg detection
futex: Fix sparc32/m68k/nds32 build regression
futex: Fix additional regressions
Ingo Molnar (1):
Merge tag 'v5.16-rc5' into locking/core, to pick up fixes
Kefeng Wang (1):
locking: Make owner_on_cpu() into <linux/sched.h>
Marco Elver (1):
locking: Mark racy reads of owner->on_cpu
Mark Rutland (1):
locking/atomic: atomic64: Remove unusable atomic ops
Peter Zijlstra (1):
locking/rtmutex: Squash self-deadlock check for ww_rt_mutex.
Sebastian Andrzej Siewior (10):
kernel/locking: Use a pointer in ww_mutex_trylock().
sched: Trigger warning if ->migration_disabled counter underflows.
locking: Remove rt_rwlock_is_contended().
locking/rtmutex: Add rt_mutex_lock_nest_lock() and rt_mutex_lock_killable().
lockdep/selftests: Avoid using local_lock_{acquire|release}().
lockdep/selftests: Unbalanced migrate_disable() & rcu_read_lock().
lockdep/selftests: Skip the softirq related tests on PREEMPT_RT
lockdep/selftests: Adapt ww-tests for PREEMPT_RT
x86/mm: Include spinlock_t definition in pgtable.
locking: Allow to include asm/spinlock_types.h from linux/spinlock_types_raw.h
Thomas Gleixner (2):
lockdep: Remove softirq accounting on PREEMPT_RT.
