The principial problem are the old pcibios_*_config_*
functions. We have two possibilities: either rewrite all drivers to
use pci_*_config_*() instead (which would be an awful lot of work)
or make them map the (bus,devfn) pair to struct pci_dev and call
pci_*_config_*() automatically. The latter approach would give us
slower backward-compatible functions, but it's probably feasible
since they are not performance critical and we can use simple
hashing, so that the overhead will be minimal.
Please, if you ever make changes along these lines, keep in your mind
the concerns of people such as Leonard Zubkoff. :-)
