This will be used by the Tyr driver to create and modify the page table of each address space on the GPU. Each time a mapping gets created or removed by userspace, Tyr will call into GPUVM, which will figure out which calls to map_pages and unmap_pages are required to map the data in question in the page table so that the GPU may access those pages when using that address space. The Rust type wraps the struct using a raw pointer rather than the usual Opaque+ARef approach because Opaque+ARef requires the target type to be refcounted.
