The (successful) end of the kernel Rust experiment

The topic of the Rust experiment was just discussed at the annual
Maintainers Summit. The consensus among the assembled developers is that
Rust in the kernel is no longer experimental — it is now a core part of the
kernel and is here to stay. So the 'experimental' tag will be coming off.
Congratulations are in order for all of the Rust for Linux team.
