Subject: [PATCH 0/4] Rust GPUVM support

This makes a few changes to the way immediate mode works, and then it
implements a Rust immediate mode GPUVM abstraction on top of that.

Please see the following branch for example usage in Tyr:
https://gitlab.freedesktop.org/panfrost/linux/-/merge_requests/53

For context, please see this previous patch:
https://lore.kernel.org/rust-for-linux/20250621-gpuvm-v3-1-10203da06867@collabora.com/
and the commit message of the last patch.

      drm/gpuvm: take GEM lock inside drm_gpuvm_bo_obtain_prealloc()
      drm/gpuvm: drm_gpuvm_bo_obtain() requires lock and staged mode
      drm/gpuvm: use const for drm_gpuva_op_* ptrs
      rust: drm: add GPUVM immediate mode abstraction
