That would be scary, imagine having enough pages in the object to
overflow unsigned long :)

We now have two implementations for vmapping a whole object, one for
dma-buf and one for the ringbuffer. If we couple the vmapping into the
obj->pages lifetime, then we can reuse an obj->vmapping for both and at
