[PATCH -next v7 0/2] rust: Add CList and GPU buddy allocator bindings

[Joel Fernandes <joelagnelf@nvidia.com>]

This series provides Rust bindings infrastructure needed for nova-core
memory management:

1. CList module for interfacing with C circular linked lists, required
   for iterating over GPU buddy allocator blocks.

2. GPU buddy allocator bindings for physical memory management in
   nova-core.

These patches are based on the RFC v6 nova-core memory management series:
https://lore.kernel.org/all/20260120204303.3229303-1-joelagnelf@nvidia.com/

Main changes from v6 are based on suggestions by Gary and Dave.

This patch requires the DRM buddy code movement patch as a prerequisite:
https://lore.kernel.org/all/20260206003451.1914130-1-joelagnelf@nvidia.com/

Rebased on linux-next commit 9845cf73f7db ("Add linux-next specific files
for 20260205").
