Merge branch 'pci/virtualization'
- To avoid bus errors, enable PASID only if entire path supports End-End TLP prefixes (Sinan Kaya) - Unify slot and bus reset functions and remove hotplug knowledge from callers (Sinan Kaya) - Add Function-Level Reset quirks for Intel and Samsung NVMe devices to fix guest reboot issues (Alex Williamson) - Add function 1 DMA alias quirk for Marvell 88SS9183 PCIe SSD Controller (Bjorn Helgaas) * pci/virtualization: PCI: Add function 1 DMA alias quirk for Marvell 88SS9183 PCI: Delay after FLR of Intel DC P3700 NVMe PCI: Disable Samsung SM961/PM961 NVMe before FLR PCI: Export pcie_has_flr() PCI: Rename pci_try_reset_bus() to pci_reset_bus() PCI: Deprecate pci_reset_bus() and pci_reset_slot() functions PCI: Unify try slot and bus reset API PCI: Hide pci_reset_bridge_secondary_bus() from drivers IB/hfi1: Use pci_try_reset_bus() for initiating PCI Secondary Bus Reset PCI: Handle error return from pci_reset_bridge_secondary_bus() PCI/IOV: Tidy pci_sriov_set_totalvfs() PCI: Enable PASID only if entire path supports End-End TLP prefixes # Conflicts: # drivers/pci/hotplug/pciehp_hpc.c
