   Looks fine to me, exactly the interface I've used/wanted. But you want
   to add the extra page/offset to the existing scatterlist, and not scrap
   that one completely?

The idea is that address/alt_address disappear sometime in 2.5.
Something like this right?

BTW, on x86 we can ifdef the dma64_address to u32 or u64 based
upon CONFIG_HIGHMEM if we wish.
