This series adds Rust abstractions for the hw_random subsystem.

A virtio-rng Rust driver that uses them will be submitted as a separate
series since it also depends on the virtio abstractions series.

Please include that at least as a reference to a branch or similar,
since in most cases the user is needed to evaluate abstractions etc.

Thanks!

Good point, thanks.

My WIP branch is here 
https://github.com/epilys/linux/tree/b4/rust-virtio-rng (HEAD is the 
driver that uses the abstraction in this series)

It uses atomics instead of a spinlock since we can't sleep during virtio 
driver probe. I didn't want to overcomplicate it by deferring all the 
sleeping work to a workqueue, but maybe it's a necessity until we get 
spinlocks that can disable IRQs.
