Grr, I dislike size_t in the kernel. It's not tied to the physical
address size, or virtual address size (or either dma or ourselves).
In most cases you really do mean unsigned long, but often there's an
explicit type you could use. Note that they need u64 math protection (or
at least using the macros for handling longs).
