The Rust kernel code should be kept `rustdoc`-clean [1].
Our custom `srctree` link checker in the `rustdoc` target reports:
warning: srctree/ link to include/io-pgtable.h does not exist
Thus fix it.

The Rust kernel code should be kept `rustfmt`-clean [1].
Thus run the `rustfmt` target to fix the formatting issue.

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.
