So, to make sure I understand your point, should I make the generic dma_get_page_shift a compile-error kind of thing? It will only fail on architectures that actually build the NVME driver (as the only caller). But I'm not sure how exactly to achieve that, if you could give a bit more detail I'd appreciate it!
