See my other email I just sent out. I really am not going to take some totally new experimental and hacky major PCI resource management thing this late in the -rc game. No way, no how. If the top-down allocator is causing regressions that cannot be fixed by _simple_ patches, we're simply going to have to undo it. What's the advantage of top-down? None. Not if we then need all this crap, which we could as easily do on top of the bottom-up one WITHOUT any regressions. Why isn't anybody else questioning the whole basic premise here?
