These macros belong in asm-i386/scatterlist.h instead.
As the headers are disentangled this has shown up as a problem with my
MCA SCSI drivers since they no-longer include asm/pci.h in any form but
need to traverse the scatterlist.

1. highmem pci dma mapping does not work, missing cast in asm-i386/pci.h
Hello all,
There's a missing cast in pci_map_page that causes 64 bit capable
drivers to access the wrong memory for highmem pages. Please
include the patch below to fix it.
