We could add such a definition and use it the same way PCI_SRIOV_NUM_BARS is used. There is already the definition PCI_BAR_COUNT for s390 only. Thus, this patchset introduces it globally. Changes in v2: - Reverse checks in pci_iomap_range,pci_iomap_wc_range. - Refactor loops in vfio_pci to keep PCI_STD_RESOURCES. - Add 2 new patches to replace the magic constant with new define. - Split net patch in v1 to separate stmmac and dwc-xlgmac patches.
