Yes, this one is obvious. But if you have IDE enabled, there are later
on a whole bunch of new functions that are undefined, and I think it
must be pretty hard to write them. In drivers/block/ide-dma.c, you get
pci_map_sg, sg_dma_len, sg_dma_address, pci_unmap_sg,
pci_free_consistent, pci_alloc_consistent all undefined.
