Merge branch 'pci/virtualization'
- probe for device reset support during enumeration instead of runtime (Bjorn Helgaas) - add ACS quirk for Ampere (née APM) root ports (Feng Kan) - add function 1 DMA alias quirk for Marvell 88SE9220 (Thomas Vincent-Cross) - protect device restore with device lock (Sinan Kaya) - handle failure of FLR gracefully (Sinan Kaya) - handle CRS (config retry status) after device resets (Sinan Kaya) - skip various config reads for SR-IOV VFs as an optimization (KarimAllah Ahmed) * pci/virtualization: PCI/IOV: Add missing prototypes for powerpc pcibios interfaces PCI/IOV: Use VF0 cached config registers for other VFs PCI/IOV: Skip BAR sizing for VFs PCI/IOV: Skip INTx config reads for VFs PCI: Wait for device to become ready after secondary bus reset PCI: Add a return type for pci_reset_bridge_secondary_bus() PCI: Wait for device to become ready after a power management reset PCI: Rename pci_flr_wait() to pci_dev_wait() and make it generic PCI: Handle FLR failure and allow other reset types PCI: Protect restore with device lock to be consistent PCI: Add function 1 DMA alias quirk for Marvell 88SE9220 PCI: Add ACS quirk for Ampere root ports PCI: Remove redundant probes for device reset support PCI: Probe for device reset support during enumeration Conflicts: include/linux/pci.h
