10 days	rust: sync: add const constructor for raw_spinlock_t	Alice Ryhl
	The abstractions for pr_*_ratelimited! need to construct a global `struct ratelimit_state`, which contains a `raw_spinlock_t` field. Thus, add a const constructor for the `raw_spinlock_t` type. The SPINLOCK_OWNER_INIT constant isn't mirrored via a const helper because bindgen generates a 'static mut' instead of a constant from the pointer constant., The __ARCH_SPIN_LOCK_UNLOCKED constant cannot be translated by bindgen because it's a define for a struct without type annotations, so it's explicitly declared in Rust.

10 days	rust: sync: move lockdep types to rust/kernel/sync/lockdep.rs	Alice Ryhl
	The lockdep types are currently stored directly in rust/kernel/sync.rs, but there are starting to be too many of them to keep them in that file. Thus, move them to a submodule. The new module is listed under LOCKING PRIMITIVES in the MAINTAINERS file. For commonly used lockdep logic it's useful to keep re-exports in kernel::sync, and this also avoids the need to update any users.
