    - Enable PROVE_RAW_LOCK_NESTING with PROVE_LOCKING (Sebastian Andrzej Siewior)
    - Add lockdep_cleanup_dead_cpu() (David Woodhouse)

 - futexes:
    - Use atomic64_inc_return() in get_inode_sequence_number() (Uros Bizjak)
    - Use atomic64_try_cmpxchg_relaxed() in get_inode_sequence_number() (Uros Bizjak)

 - RT locking:
    - Add sparse annotation PREEMPT_RT's locking (Sebastian Andrzej Siewior)

 - spinlocks:
    - Use atomic_try_cmpxchg_release() in osq_unlock() (Uros Bizjak)

 - atomics:
    - x86: Use ALT_OUTPUT_SP() for __alternative_atomic64() (Uros Bizjak)
    - x86: Use ALT_OUTPUT_SP() for __arch_{,try_}cmpxchg64_emu() (Uros Bizjak)

 - KCSAN, seqlocks:
    - Support seqcount_latch_t (Marco Elver)

 - <linux/cleanup.h>:
    - Add if_not_cond_guard() conditional guard helper (David Lechner)
    - Adjust scoped_guard() macros to avoid potential warning (Przemek Kitszel)
    - Remove address space of returned pointer (Uros Bizjak)

 - WW mutexes:
    - locking/ww_mutex: Adjust to lockdep nest_lock requirements (Thomas Hellström)

 - Rust integration:
    - Fix raw_spin_lock initialization on PREEMPT_RT (Eder Zulian)

 - miscellaneous cleanups & fixes:
    - lockdep: Fix wait-type check related warnings (Ahmed Ehab)
    - lockdep: Use info level for initial info messages (Jiri Slaby)
    - spinlocks: Make __raw_* lock ops static (Geert Uytterhoeven)
    - pvqspinlock: Convert fields of 'enum vcpu_state' to uppercase (Qiuxu Zhuo)
    - iio: magnetometer: Fix if () scoped_guard() formatting (Stephen Rothwell)
