We're getting close to the new merge window, and I _think_ this
patch series is ready for consideration. Notably:

	- multiple rescans/removes of devices with and without bridges
	- verified that resource allocation after multiple remove/rescan
	  cycles is the same as what we had during initial boot
	- fixes the complete suckage of fakephp (that I created)
	- doesn't affect existing hotplug drivers
	- tested on x86 and ia64 platforms

Please review, and consider testing. For testing ease, you can pull
from my git branch:

	git://git.kernel.org/pub/scm/linux/kernel/git/achiang/pci-hotplug.git
	branch 'test-20090318' is what you want

Note, this test branch does contain the small assorted patches in AER
and the PCIe portdriver that I fixed along the way, but does not contain
the sysfs callback mutex that I introduced to protect myself from
Vegard Nossum. ;) If you want to hammer away at the sysfs interface,
please apply this patch on top:

	http://thread.gmane.org/gmane.linux.kernel/806648

What I'm continuing to do:

	- investigate converting existing hotplug drivers to use
	  new pci_rescan_bus() interface

Thanks.

/ac

v3 -> v4:
	- protect sysfs interfaces with mutex
	- undo changes in pci_do_scan_bus
	- introduce pci_rescan_bus instead
	- do not initialize bridges more than once

v2 -> v3:
	- properly remove device with internal bridge
	- added Kenji Kaneshige's pci_is_root_bus() interface
	- dropped whitespace cleanups for another time

v1 -> v2:
	- incorporated lots of Trent Piepho's work
	- beefed up pci_do_scan_bus as heavy lifter for rescanning
	- small bugfixes folded into earlier patches to get everything working
