This is a note to let you know that I've just added the patch titled
PCI: acpiphp: Re-enumerate devices when host bridge receives Bus Check
to the 3.9-stable tree which can be found at:
http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary
The filename of the patch is:
pci-acpiphp-re-enumerate-devices-when-host-bridge-receives-bus-check.patch
and it can be found in the queue-3.9 subdirectory.
If you, or anyone else, feels it should not be added to the stable tree,
please let <stable@xxxxxxxxxxxxxxx> know about it.

And this one fails to link because of the previous ones not being
present, so it's now dropped as well...
What are previous ones?
668192b678 ("PCI: acpiphp: Move host bridge hotplug to
pci_root.c") is not in your tree?
The problem is you didn't export acpiphp_check_host_bridge. And I think
you would have to remove the module_exit function from acpiphp rather
than just clearing that pointer and hoping no-one called through it
recently.
Alternately, Greg could just cherry-pick commit
6037a803b05eef9943fb64982e19964007fb7478 'PCI: acpiphp: Convert acpiphp
to be builtin only, not modular'. acpiphp was never very useful as a
module since it didn't get auto-loaded.
We couldn't auto-load it as that would have broken some systems a number
of years ago, that's why I did it that way.
Even with cherry-picking 6037a803b05eef9943fb64982e19964007fb7478,
commit 3f327e39b4b8f760c331bb2836735be6d83fbf53 doesn't apply properly,
so I'll just wait for a developer to care enough to send me patches that
actually apply and build properly for 3.9-stable if they want them there
:)
Honestly, I'm not sure about backporting 'PCI: acpiphp: Convert acpiphp
to be builtin only, not modular' and things depending on it to -stable,
as it is a major redesign of the subsystem and we can easily break stuff
while doing the backport, in which case we'll have bugs in -stable that
aren't present in the mainline.
Thanks,
Rafael
