BTW, let me expand on this one. The sg_list change was dropped, davem
and I decided to evolve the current scatterlist in two steps:

- add ->page and ->offset and have the PCI DMA mapping interface use
that if available. This step has already been taken with the pci64
patches.

- Remove ->address completely. This step must be taken to ensure that
drivers will be highmem safe. Period. Don't know when we will do this
yet.
