  PCI: Only check the HT capability bits in mpic.c
  PCI: Use pci_find_ht_capability() in drivers/pci/quirks.c
  PCI: Add #defines for Hypertransport MSI fields
  PCI: Use pci_find_ht_capability() in drivers/pci/htirq.c
  PCI: Add pci_find_ht_capability() for finding Hypertransport capabilities
  PCI: Create __pci_bus_find_cap_start() from __pci_bus_find_cap()
  pci: Introduce pci_find_present
  PCI: pcieport-driver: remove invalid warning message
