On PHB3, some PEs might be reserved in advance to reflect the M64 segments consumed by those PEs. We're reserving PEs based on the M64 window of root port, which might contain VF BAR. The PEs for VFs are allocated dynamically, not reserved based on the consumed M64 segments. So the M64 window of root port isn't reliable for the task. Instead, we go through M64 BARs (VF BARs excluded) of PCI devices under the specified root bus and reserve PEs accordingly, as the patch does.
