    dyntick has all the hallmarks of ending up another mess just like the
    "generic" (hahaha) irq stuff in kernel/irq - it's being developed in
    precisely the same way - by ignore non-x86 stuff.

    I can well see that someone will say "ok, this is ready, merge it"
    at which point we then end up with multiple differing userspace
    methods of controlling it depending on the architecture, but
    multiple differing kernel interfaces as well.

    Indeed, you seem to be at the point where you'd like akpm to merge
    it. That sets alarm bells ringing if you haven't considered these

    I want to avoid that. Just because a couple of people say "we'll
    deal with that later" it's no guarantee that it _will_ happen. I
    want to ensure that ARM doesn't get fscked over again like it did
    with the generic IRQ crap.
