Alexey Kardashevskiy d6f934fd48 powerpc/powernv: Reserve a hole which appears after enabling IOV ... In order to make generic IOV code work, the physical function IOV BAR should start from offset of the first VF. Since M64 segments share PE number space across PHB, and some PEs may be in use at the time when IOV is enabled, the existing code shifts the IOV BAR to the index of the first PE/VF. This creates a hole in IOMEM space which can be potentially taken by some other device. This reserves a temporary hole on a parent and releases it when IOV is disabled; the temporary resources are stored in pci_dn to avoid kmalloc/free.
