Here is v5 of this series that addresses the review comments from v4.
I've pushed out a new test tree that contains the updated series for testing. The tree consists of:
Linus's v2.6.28 + Jesse's linux-next queue (as of 19 March 2009) + the 13 patches in this series
It does not contain the sysfs callback patch that is required for interface torture tests. That can be had here:
http://thread.gmane.org/gmane.linux.kernel/806648
You can pull my tree here:
git://git.kernel.org/pub/scm/linux/kernel/git/achiang/pci-hotplug.git test-20090319
This is also a nice chance to test the shiny new patchwork instance that we have running on kernel.org that we hope to use for linux-pci in the future:
http://patchwork.kernel.org/project/linux-pci/list/
I still haven't figured out the locking issue that Kenji-san pointed out from last time, because I haven't been able to reproduce it.
Any further testing/review is welcomed and appreciated.
Thanks!

v4 -> v5: - acquire pci_bus_sem when walking device list in pci_rescan_bus - keep CONFIG_HOTPLUG (instead of CONFIG_HOTPLUG_PCI) - comment why we need device_schedule_callback() - remove CAP_SYS_ADMIN check - do not remove primary bus in remove_callback() - do not enable bridges multiple times - checkpatch cleanups
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
