I doubt your reasoning is cogent enough. If you add such a global thing,
you should prove it, or clearly explain what is the thing for.
I don't believe that it's not possible to solve that decrementer case
without this change. Can't you add appropriate platform_device which
would register early enough, to meet that timing requirement when it
gets suspended?

So, where is that callbacks that are so desirable for powermac?
Thanks,
