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
