But that doesn't work if you build a combined v5/v6/v7 kernel, because
v5 supports neither form, right? I think to do that, it needs the
same kind of abstraction that we have for a number of other things
like cache management in arch/arm/mm/.

The options are kernels which support v3-v5 or v6-v7.  There's too big
a change between v5 and v6 to combine those into one kernel.
