The point is that the Linux kernel is built around portability to
whatever architecture you want to run it on.

You can get a C compiler for everything someone could be interested
in running the Linux kernel on. However, until you can make the same
guarantee for Rust, then Rust will be restricted to the non-core
parts of the Linux kernel (ie: some device drivers) because otherwise
Rust suddenly becomes the reason why you can't run Linux on some
specialist architecture.
