It reaches the end of the address space, sets last_iova back to 0, and just continues. So the MMU fault is somehow specific to what I'm doing.

This does happen when rendering - it keeps dealing out iovas near the end of the address space. But that seems harmless, though maybe causes some more MMU flushes than necessary.
