Atleast for the rc fix, we should do exactly this. Right.

But we can rethink about getting both my earlier patches merged for
4.3, which did this:

- Keep adding CPUs to a global mask, which didn't had a existing
  policy and were offline when subsys-callback for called for them.
- And then create the links only when the subsys callback is called
  for CPUs, for which policy already exist, as Russell suggested.
