[PATCH v5 00/13] PCI core learns hotplug

[Alex Chiang]

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
