Regardless of PCIe hotplug, some of PCIe devices (not on hotplug
slots) doesn't work with your patches by the following error.

I'm using Jesse's latest linux-next.
I'm attaching the /proc/iomem outputs. The iomem-default.txt is
/proc/iomem output without your patches. The iomem-yinghai.txt
is /proc/iomem output with your patches.

Thanks,
Kenji Kaneshige
