Hi all,

This is v4 of the series that implements a series of changes
that allows the PCI core to manage slot names, rather than
individual hotplug drivers.

Thank you to Kenji-san and Taku-san for testing and finding my bugs.
Thanks to Willy for helping me out with the locking issues in
pci_hp_register.

Again, I have tested by loading pci_slot, acpiphp, and fakephp in various
combinations, and using the new dup_slots=1 param to fakephp. I also had:

CONFIG_DEBUG_SPINLOCK=y
CONFIG_DEBUG_MUTEXES=y
CONFIG_DEBUG_SPINLOCK_SLEEP=y

and didn't see any complaints.

This series applies against Jesse's linux-next branch. I just fetched his
branch and peeked at it, and based on the log, my series _should_ apply
with minimal fuzz (but I didn't do a rebase because I didn't think to
check until writing this mail ;).

It would be great if folks could give one last (hopefully!) review.

Thanks.

/ac

v3 -> v4:
	- Do not access hotplug_slot_name() before name initialization
	- Serialize pci_hp_register/deregister

v2 -> v3:
	- incorporate Willy's code review comments
	- fix possible memory leak, pointed out by Rolf Eike Beer
	- make false name collision detection work for empty slots
	- add 'dup_slots' module_param to fakephp to help debug all this ;)

v1 -> v2:
	- fix possible false name collisions
