[PATCH v2, part 1 0/9] Prepare for introducing PCI bus lock interfaces

[Jiang Liu]

This is a preparation patchset for introducing PCI bus lock mechanisms
to protect PCI subsystem from concurrent hotplug operations.

Patch 1:
	Introduce pci_bus_{get|put}() to manage PCI bus reference count
Patch 2-3:
	pci_alloc_dev() patchset from Gu Zheng
Patch 8:
	Make PCI bus creating/destroying logic symmetric
Other:
	Minor code improvements/cleanups

Gu Zheng (2):
  PCI: Introduce pci_alloc_dev(struct pci_bus*) to replace
    alloc_pci_dev()
  PCI: Convert alloc_pci_dev(void) to pci_alloc_dev(bus) instead

Jiang Liu (7):
  PCI: introduce pci_bus_{get|put}() to manage PCI bus reference count
  PCI: mark pci_scan_bus_parented() as __deprecated
  ACPI, PCI: remove unused global list acpi_pci_roots in pci_root.c
  ACPI, pci_root: use acpi_handle_print() and pr_xxx() to print messages
  PCI, IA64: minor code clean up
  PCI: make PCI host bridge/bus creating and destroying logic symmetric
  PCI, unicore, m68k: remove redundant call of pci_bus_add_devices()
