Subject: [PATCH 0/16] ACPI: Rework ACPI namespace scanning for devices

Hi all,

I've finally cut the patches removing acpi_pci_bind() and acpi_pci_unbind(),
so I'm kind of ready to post the entire series reworking the ACPI namespace
scanning code.

Patches [1-6/16] are essentially these ones:

https://patchwork.kernel.org/patch/1889821/
https://patchwork.kernel.org/patch/1876481/
https://patchwork.kernel.org/patch/1876531/
https://patchwork.kernel.org/patch/1876571/
https://patchwork.kernel.org/patch/1876511/
https://patchwork.kernel.org/patch/1876401/

but [2-6/16] have been rebased on top of the first one.

Patches [7-12/16] are essentially these:

https://patchwork.kernel.org/patch/1884721/
https://patchwork.kernel.org/patch/1884701/
https://patchwork.kernel.org/patch/1884761/
https://patchwork.kernel.org/patch/1884731/
https://patchwork.kernel.org/patch/1884751/
https://patchwork.kernel.org/patch/1884661/

but they have been rebased on top of https://patchwork.kernel.org/patch/1889821/.
I added Yinghai's ACKs to them tentatively, although they are a bit different
from the previous versions.  The difference is not too important, however,
because the following patches finally remove the acpi_pci_bind()/acpi_pci_unbind()
stuff:

[13/16] Add .setup() and .cleanup() callbacks to struct acpi_bus_type.
[14/16] Rework the setup and cleanup of ACPI/PCI device wakeup.
[15/16] Move the _PRT setup and cleanup code to pci-acpi.c.
[16/16] Drop ACPI device .bind() and .unbind() callbacks.

This is done a bit differently than I thought it would be, mostly because the
_PRT-related operations require the "subordinate" pointers of bridges to be
populated.  I think it may be possible to simplify this further if that
requirement can be removed (I haven't looked into that).

In fact, patches [13-15/16] do not essentially depend on [1-12/16], only the
last one does.

The patches are on top of my master branch and I'm going to rebase them when
v3.8-rc1 is out.

There is a git tree you can pull them from at:

http://git.kernel.org/?p=linux/kernel/git/rafael/linux-pm.git;a=summary acpi-scan-temp-new

It's v3.7 with my master branch merged and the new patches on top.

Thanks,
Rafael
