[PATCH v3, part1 00/10] Prepare for introducing PCI bus lock interfaces

[Jiang Liu <liuj97@gmail.com>]

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 6:
	Make PCI bus creating/destroying logic symmetric
Patch 8-10:
	Cleanup and bugfix for IOV
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 (8):
  PCI: introduce pci_bus_{get|put}() to manage PCI bus reference count
  PCI: mark pci_scan_bus_parented() as __deprecated
  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()
  PCI, IOV: don't touch bus->is_added flag
  PCI, IOV: simplify IOV implementation
  PCI, IOV: hide remove and rescan sysfs interfaces for SR-IOV virtual
    functions
