Note, I think the patch above is broken and slipped by me because I
forgot to make clean - I'll doublecheck tomorrow.

How, though - AFAIK linux has no drivers specifically intended to feed
entropy into the kernels pool - all the hwrng drivers use a userspace
tool to do so.

I still intend to submit my virtio-rng driver, if thats what you mean,
since it presents the data via the same routes as all the other hw rng
sources. I feel this approach has value.
