I've committed a bunch of these to:

    https://git.kernel.org/pub/scm/linux/kernel/git/crng/random.git/log/

For a v3, if you rebase on there, that'd make things easier for me to
keep picking patches that I intend to send out for 6.11-rc6 later this
week. And then hopefully your 6.12 ppc implementation can just go in via
the ppc tree with my eventual ack on the crypto part, without needing
these interdependencies.
