[PATCH v2 0/2] rust: add a few helpers

[Andreas Hindborg <a.hindborg@kernel.org>]

This series adds two helpers for obtaining information about the number
of numa domains and cpu count of the system.

Signed-off-by: Andreas Hindborg <a.hindborg@kernel.org>

Changes in v2:
- Move helpers out of the crate root into the `cpu` and `numa`
  modules (Miguel).
- Mark Rust wrappers `#[inline]` (Alice).
- Mark the `num_possible_cpus` C helper `__rust_helper` (Dirk).
- Mention the Rust null block driver as the consumer in commit
  messages (Miguel).
- Link to v1: https://msgid.link/20260215-cpu-helpers-v1-0-fab13d817a5e@kernel.org
