We can solve the conflict easily that way. But that's not the point.
The point is that I've been fighting hard to consolidate dma code given that the behavior really is common and not arch specific. And this one is another case like that: the fact that the non-coherent dma boundary is bigger than the exposed size is something that can easily happen elsewhere, so there is no need to duplicate a lot of code for that.
Nevermind that the commit should at least be three different patches:
(1) revert the broken original commit (2) increase the dma min alignment (3) put the swiotlb workaround in place
