Subject: [PATCH v2 00/11] Dynamic ACPI-PCI binding

Hi Len,

I hope this isn't too late for the .31 merge window. If so, no big deal;
this patchset isn't urgent, it's just a nice cleanup that was inspired
from investigating the recent bug in acpi_pci_bind() (fixed by dacd254).

This patch series eliminates static boot-time binding of ACPI
and PCI devices, and introduces an API to perform this lookup
during runtime.

This change has the following advantages:

	- eliminates struct acpi_device vs struct pci_dev lifetime issues
	- lays groundwork for eliminating .bind/.unbind from acpi_device_ops
	- lays more groundwork for eliminating .start from acpi_device_ops
	  and thus simplifying ACPI drivers
  	- whacks out a lot of code

This patchset is based on lenb/test (66c74fa1d4), and has been boot
tested on ia64 and x86. I also performed physical PCI hotplug tests
using acpiphp on ia64. I do not have an acpiphp-capable x86 platform.

I didn't test the changes in the video driver either, as I don't have
the hardware.

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. :)

Alex Chiang (11):
      ACPI: kill acpi_get_physical_pci_device()
      ACPI: video: convert to acpi_get_pci_dev
      ACPI: kill acpi_get_pci_id
      PCI Hotplug: acpiphp: convert to acpi_get_pci_dev
      ACPI: acpi_pci_unbind should clean up properly after acpi_pci_bind
      ACPI: simplify acpi_pci_irq_del_prt() API
      ACPI: simplify acpi_pci_irq_add_prt() API
      ACPI: eviscerate pci_bind.c
      ACPI: Introduce acpi_get_pci_dev()
      ACPI: Introduce acpi_is_root_bridge()
      ACPI: make acpi_pci_bind() static
