Crate kernel

The kernel crate.

This crate contains the kernel APIs that have been ported or wrapped for usage by Rust code in the kernel and is shared by all of them.

In other words, all the rest of the Rust code in the kernel (e.g. kernel modules written in Rust) depends on core, alloc and this crate.

If you need a kernel C API that is not ported or wrapped yet here, then do so first instead of bypassing this crate.
