You should only need to move struct sunxi_mc_smp_data, since you are reading
the is_sun9i field. I suppose you could also get away with adding a global
variable just for that, and not have to store an index or pointer. Then none
of this code movement would be necessary. It would be slightly harder to
understand, but it's still contained within this file, and it has a clear
purpose, so I would call that acceptable.
