This series provides CList module for interfacing with linked lists, GPU buddy
allocator bindings for physical memory management in nova-core and nova-core
Kconfig change to select GPU_BUDDY.

The clist patch (patch 1) is independent and go through any tree. The other 2
patches depend on the DRM buddy code movement patch as a prerequisite, a
version of which is now in drm-misc-next:
https://lore.kernel.org/all/20260206003451.1914130-1-joelagnelf@nvidia.com/

Based on linux-next.
