Browse Source 
* pci/virtualization:
  PCI: Document reset method return values
  PCI: Detach driver before procfs & sysfs teardown on device remove
  PCI: Apply Cavium ThunderX ACS quirk to more Root Ports
  PCI: Set Cavium ACS capability quirk flags to assert RR/CR/SV/UF
  PCI: Restore ARI Capable Hierarchy before setting numVFs
  PCI: Create SR-IOV virtfn/physfn links before attaching driver
  PCI: Expose SR-IOV offset, stride, and VF device ID via sysfs
  PCI: Cache the VF device ID in the SR-IOV structure
  PCI: Add Kconfig PCI_IOV dependency for PCI_REALLOC_ENABLE_AUTO
  PCI: Remove unused function __pci_reset_function()
  PCI: Remove reset argument from pci_iov_{add,remove}_virtfn()
