Pull locking updates from Ingo Molnar:
 "Lockdep:

   - Improve and fix lockdep bitsize limits, clarify the Kconfig
     documentation (Carlos Llamas)

   - Fix lockdep build warning on Clang related to
     chain_hlock_class_idx() inlining (Andy Shevchenko)

   - Relax the requirements of PROVE_RAW_LOCK_NESTING arch support by
     not tying it to ARCH_SUPPORTS_RT unnecessarily (Waiman Long)

  Rust integration:

   - Support lock pointers managed by the C side (Lyude Paul)

   - Support guard types (Lyude Paul)

   - Update MAINTAINERS file filters to include the Rust locking code
     (Boqun Feng)

  Wake-queues:

   - Add raw_spin_*wake() helpers to simplify locking code (John Stultz)

  SMP cross-calls:

   - Fix potential data update race by evaluating the local cond_func()
     before IPI side-effects (Mathieu Desnoyers)

  Guard primitives:

   - Ease [c]tags based searches by including the cleanup/guard type
     primitives (Peter Zijlstra)

  ww_mutexes:

   - Simplify the ww_mutex self-test code via swap() (Thorsten Blum)

  Static calls:

   - Update the static calls MAINTAINERS file-pattern (Jiri Slaby)"
