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