Hi Len,
Bjorn suggested I respin this series one more time, so here it is.
Previous cover patches for rationale:
v1 - http://lkml.org/lkml/2009/6/2/282
v2 - http://lkml.org/lkml/2009/6/4/31
Thanks.
/ac
Changelog:
v2 -> v3
- incorporate Kenji's comment re: acpi_pci_unbind
- add an extra code movement patch to make evisceration easier to read
v1 -> v2
- rearrange series into a more logical order
- much simpler acpi_is_root_bridge() implementation
- no longer export acpi_pci_find_root()
- no longer leak memory in acpi_get_pci_dev()
- no longer leak references in acpi_pci_unbind/acpi_pci_bind
- convert video driver to use acpi_get_pci_dev()
- kill off acpi_get_physical_pci_device()
- incorporate Bjorn's other comments. :)

acpi_pci_root_add() explicitly assigns device->ops.bind, and later
calls acpi_pci_bind_root(), which also does the same thing.
We don't need to repeat ourselves; removing the explicit assignment
allows us to make acpi_pci_bind() static.

Convert an ACPI CA handle to a struct pci_dev.
Performing this lookup dynamically allows us to get rid of the
ACPI-PCI binding code, which:
- eliminates struct acpi_device vs struct pci_dev lifetime issues
- lays more groundwork for eliminating .start from acpi_device_ops
and thus simplifying ACPI drivers
- whacks out a lot of code
This change lays the groundwork for eliminating much of pci_bind.c.
Although pci_root.c may not be the most logical place for this
change, putting it here saves us from having to export acpi_pci_find_root.

int
acpi_pci_bind_root(struct acpi_device *device,
struct acpi_pci_id *id, struct pci_bus *bus)
Now that we can dynamically convert an ACPI CA handle to a
struct pci_dev at runtime, there's no need to statically bind
them during boot.
acpi_pci_bind/unbind are vastly simplified, and are only used
to evaluate _PRT methods on P2P bridges and non-bridge children.
This patch also changes the time-space tradeoff ever so slightly.
Looking up the ACPI-PCI binding is never in the performance path, and by
eliminating this caching, we save 24 bytes for each _ADR device in the
ACPI namespace.
This patch lays further groundwork to eventually eliminate
the acpi_driver_ops.bind callback.

/* Arch-defined function to add a bus to the system */
Returns whether an ACPI CA node is a PCI root bridge or not.
This API is generically useful, and shouldn't just be a hotplug function.
The implementation becomes much simpler as well.

There is no need to pass a segment/bus tuple to this API, as the callsite
always has a struct pci_bus. We can derive segment/bus from the
struct pci_bus, so let's take this opportunit to simplify the API and
make life easier for the callers.

A PCI domain cannot change as you descend down subordinate buses, which
makes the 'segment' argument to acpi_pci_irq_add_prt() useless.
Change the interface to take a struct pci_bus *, from whence we can derive
the bus number and segment. Reducing the number of arguments makes life
simpler for callers.

This seem to panic initialization of i915 on Dell XPS M1330.
At least the bisection points at this commit (1e4cffe78e1decd9
in Linus' tree past 2.6.31-rc1).
I couldn't get the very first dump (it is scrolled away), but the last
looks like this:
http://home.arcor.de/fork0/bug/i915-init-panic.jpg (which may
be very useless already. Sorry)
lspci output and .config attached.
Hi Alex,
Thanks for the bug report and sorry for the troubles.
I've already got a debug patch here:
http://thread.gmane.org/gmane.linux.kernel/857228/focus=857468
Perhaps you can try it too?
Len, in the mean time, can you please apply this as an emergency,
"let's not crash anyone else's machine" while I try and figure
out why the ACPI video driver breaks my assumptions?
Troy, I applied your S-o-B, but maybe that was not a good
assumption on my part? To be sure, could you please respond with
your S-o-B?
Thanks.

ACPI: prevent NULL deref in acpi_get_pci_dev()
When the ACPI video driver initializes, it does a namespace walk
looking for for supported devices. When we find an appropriate
handle, we walk up the ACPI tree looking for a PCI root bus, and
then walk back down the PCI bus, assuming that every device
inbetween is a P2P bridge.
This assumption is not correct, and is reported broken on at
least:
Dell Latitude E6400
ThinkPad X61
Dell XPS M1330
Add a NULL deref check to prevent boot panics.

Sure, for the record,

I also tried out your debug patch on my machine, which was hitting the
problem (it's an Acer Aspire 5100). I put a small patchlet on top of it,
to get the names out right (see below). The dmesg and lspci output are
attached.
If you'd like me to do anything else, just let me know.

This patch helped, does not panic anymore.

Here's the output from my machine, including ACPI paths (summary of not
found stuff at the top):

So looks like one is an express slot, another is the AGP this machine
lacks, and then there's this 05:00.0; not sure what that is.
At any rate, it does appear we have to take care not to assume
*everything* in the ACPI tree has an associated PCI dev, since
namespaces could be shared accross different platforms with just enable
or present bits to mask them out from the initial PCI scan.

Yup, as per our irc discussion, I'm now a lot more confident that
this was the root cause.

I'll send a patch updating acpi_get_pci_dev() with a comment that
explains the "why".
Thanks everyone.
