Rust in Linux-Next

Rust will be relegated to drivers for the foreseeable future, and so they won't be affected, given that new drivers wouldn't be written in Rust for platforms that don't support Rust.

In the future, who knows. Some folks are working on a GCC Rust implementation, that may be the path forward, or more LLVM backends may happen... only time will tell.

Too much attention is put on if something is tier 2 or tier 3. It doesn't actually say that much about if you can use Rust on the platform or not.

It:

- integrates rustc into the linux kernel build system

- sets up automated binding generation to allow accessing C Kernel APIs from Rust using bindgen

- Creates idiomatic rust wrappers around some of those bindings, which is meant to be used by device writers.

There's more information in the Rust-for-Linux repo[0] (which is the origin for the linux in rust effort), and in the Documentation/rust[1] folder.
