* master.kernel.org:/pub/scm/linux/kernel/git/gregkh/pci-2.6: (22 commits)
  acpiphp: Link-time error for PCI Hotplug
  shpchp: cleanup shpchp.h
  shpchp: remove shpchprm_get_physical_slot_number
  shpchp: cleanup struct controller
  shpchp: remove unnecessary struct php_ctlr
  PCI: ATI sb600 sata quirk
  PCI legacy resource fix
  PCI: don't export device IDs to userspace
  PCI: Be a bit defensive in quirk_nvidia_ck804() so we don't risk dereferencing a NULL pdev.
  PCI: Fix multiple problems with VIA hardware
  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
  rpaphp: compiler warning cleanup
  PCI quirks: remove redundant check
