Thanks for pointing out the issue Ming. I must admit that I haven't referred
to the PCI spec when sending in my "fix" since the upstream patch sort of
made sense. OTOH, you can't really call the kvm tool PCI implementation spec
compliant :)

Pekka, we can either revert my patch completely since the issue won't ever be
visible (since the pci tree got rebase) or just keep it in. Let me know what you
prefer.


Thanks,
Sasha
