Part of the problem is that our PCI layer kludges all this around. First we read bus addresses into a struct resource, then we hand it off to arch code that frobs the struct resource. We also have struct pci_bus_region which is supposed to represent bus addresses, but we don't use it consistently. I've wanted to fix this for a while, but there always seems to be something more urgent to do. Plus it means fixing up a lot of architectures. -- Matthew Wilcox Intel Open Source Technology Centre "Bill, look, we understand that you're interested in selling us this operating system, but compare it to ours.
