[PATCH v2 00/10] Add definition for the number of standard PCI BARs

Code that iterates over all standard PCI BARs typically uses
PCI_STD_RESOURCE_END, but this is error-prone because it requires
"i <= PCI_STD_RESOURCE_END" rather than something like
"i < PCI_STD_NUM_BARS". 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.

Denis Efremov (10):
PCI: Add define for the number of standard PCI BARs
s390/pci: Loop using PCI_STD_NUM_BARS
x86/PCI: Loop using PCI_STD_NUM_BARS
stmmac: pci: Loop using PCI_STD_NUM_BARS
net: dwc-xlgmac: Loop using PCI_STD_NUM_BARS
rapidio/tsi721: Loop using PCI_STD_NUM_BARS
efifb: Loop using PCI_STD_NUM_BARS
vfio_pci: Loop using PCI_STD_NUM_BARS
PCI: hv: Use PCI_STD_NUM_BARS
PCI: Use PCI_STD_NUM_BARS
