Merge branches 'pci/hotplug', 'pci/iommu', 'pci/irq' and 'pci/virtualization' into next

* pci/hotplug:
  PCI: pciehp: Remove ignored MRL sensor interrupt events
  PCI: pciehp: Remove unused interrupt events
  PCI: pciehp: Handle invalid data when reading from non-existent devices
  PCI: Hold pci_slot_mutex while searching bus->slots list
  PCI: Protect pci_bus->slots with pci_slot_mutex, not pci_bus_sem
  PCI: pciehp: Simplify pcie_poll_cmd()
  PCI: Use "slot" and "pci_slot" for struct hotplug_slot and struct pci_slot

* pci/iommu:
  PCI: Remove pci_ats_enabled()
  PCI: Stop caching ATS Invalidate Queue Depth
  PCI: Move ATS declarations to linux/pci.h so they're all together
  PCI: Clean up ATS error handling
  PCI: Use pci_physfn() rather than looking up physfn by hand
  PCI: Inline the ATS setup code into pci_ats_init()
  PCI: Rationalize pci_ats_queue_depth() error checking
  PCI: Reduce size of ATS structure elements
  PCI: Embed ATS info directly into struct pci_dev
  PCI: Allocate ATS struct during enumeration
  iommu/vt-d: Cache PCI ATS state and Invalidate Queue Depth

* pci/irq:
  PCI: Kill off set_irq_flags() usage

* pci/virtualization:
  PCI: Add ACS quirks for Intel I219-LM/V
