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. Jason
