- neaten pci=earlydump output (Andy Shevchenko)

  - avoid errors when extended config space inaccessible (Gilles Buloz)

  - prevent sysfs disable of device while driver attached (Christoph
    Hellwig)

  - use core interface to report PCIe link properties in bnx2x, bnxt_en,
    cxgb4, ixgbe (Bjorn Helgaas)

  - remove unused pcie_get_minimum_link() (Bjorn Helgaas)

* pci/enumeration:
  PCI: Remove unused pcie_get_minimum_link()
  ixgbe: Report PCIe link properties with pcie_print_link_status()
  cxgb4: Report PCIe link properties with pcie_print_link_status()
  bnxt_en: Report PCIe link properties with pcie_print_link_status()
  bnx2x: Report PCIe link properties with pcie_print_link_status()
  PCI: Prevent sysfs disable of device while driver is attached
  PCI: Check whether bridges allow access to extended config space
  x86/PCI: Make pci=earlydump output neat
