操作

Merge branches 'pci/aer', 'pci/enumeration', 'pci/kconfig', 'pci/misc',... 

Merge branches 'pci/aer', 'pci/enumeration', 'pci/kconfig', 'pci/misc', 'pci/virtualization' and 'pci/vpd' into next

* pci/aer:
  PCI/AER: Log aer_inject error injections
  PCI/AER: Log actual error causes in aer_inject
  PCI/AER: Use dev_warn() in aer_inject
  PCI/AER: Fix aer_inject error codes

* pci/enumeration:
  PCI: Fix broken URL for Dell biosdevname

* pci/kconfig:
  PCI: Cleanup pci/pcie/Kconfig whitespace
  PCI: Include pci/hotplug Kconfig directly from pci/Kconfig
  PCI: Include pci/pcie/Kconfig directly from pci/Kconfig

* pci/misc:
  PCI: Add PCI_CLASS_SERIAL_USB_DEVICE definition
  PCI: Add QEMU top-level IDs for (sub)vendor & device
  unicore32: Remove unused HAVE_ARCH_PCI_SET_DMA_MASK definition
  PCI: Consolidate PCI DMA constants and interfaces in linux/pci-dma-compat.h
  PCI: Move pci_dma_* helpers to common code
  frv/PCI: Remove stray pci_{alloc,free}_consistent() declaration

* pci/virtualization:
  PCI: Wait for up to 1000ms after FLR reset
  PCI: Support SR-IOV on any function type

* pci/vpd:
  PCI: Prevent VPD access for buggy devices
  PCI: Sleep rather than busy-wait for VPD access completion
  PCI: Fold struct pci_vpd_pci22 into struct pci_vpd
  PCI: Rename VPD symbols to remove unnecessary "pci22"
  PCI: Remove struct pci_vpd_ops.release function pointer
  PCI: Move pci_vpd_release() from header file to pci/access.c
  PCI: Move pci_read_vpd() and pci_write_vpd() close to other VPD code
  PCI: Determine actual VPD size on first access
  PCI: Use bitfield instead of bool for struct pci_vpd_pci22.busy
  PCI: Allow access to VPD attributes with size 0
  PCI: Update VPD definitions
