Ah, I know what's going on there - the dma_range_map stuff has overlooked a subtlety, but it's easily fixed.
[ 2.269752] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000
...although either way that's really not how we should subsequently handle failing to allocate a pagetable. I guess I'll take a look into what the deal is there as well :(
