Agreed. Can you send a patch?

I can carry the commits to add arch_random_init() the generic version,
and the patch to call it after suspend/resume. I'll do this at the
very head of the random tree, and make sure it gets pushed to Linus
early during the next merge window.

Does that sound like a plan? Or does someone want to suggest
something different? I'm flexible...
