I'd suggest spitting the core part out from the arch-specific parts. That way, the core part can merged independently and architectures can move over as they see fit. It also signals (at least to me) that, "hey, I should probably review this" whilst my current stance is "there's a whole load of stuff under mm/ that needs to be acked first". If you put the whole thing into next, you just run the risk of conflicts with all the arch trees.
