Hmm. Not sure what you mean by "a peer". pci config-space i/o is done
through callbacks in the pci bus->ops structure. The PCI error recovery
is done via callbacks in the pci dev structure.  Was there something 
you'd like to see done differently?

Given GregKH's remarks, it sounded like there was some interest in 
a "struct bus_host_bridge" abstraction, and I'd be willing
to take a shot at that, provided there is general interest and 
general agreement.  I'm not quite sure what such a struct might 
contain, just yet, I'm just imagining it might be non-empty.

I kept looking at AER, and could not figure out what to do 
with it.
