Merge branch 'pci/virtualization' into next

* pci/virtualization:
  PCI: Remove __pci_dev_reset() and pci_dev_reset()
  PCI: Split ->reset_notify() method into ->reset_prepare() and ->reset_done()
  PCI: Protect pci_error_handlers->reset_notify() usage with device_lock()
  PCI: Protect pci_driver->sriov_configure() usage with device_lock()
  PCI: Mark Intel XXV710 NIC INTx masking as broken
  PCI: Restore PRI and PASID state after Function-Level Reset
  PCI: Cache PRI and PASID bits in pci_dev
