All Reference Objects returned via the AcpiEvaluteObject interface
are now marked as type "REFERENCE" instead of "ANY". The type ANY
is now reservered for NULL objects - either NULL package elements
or unresolved named references.

In some machines some GPE is shared by several ACPI devices, for example:
sleep button, keyboard, mouse. At the same time one of them is
non-wake(runtime) device and the other are wake devices. In such case OSPM
should call the _PSW object to disable the device's ability to
wake the sleeping system in the boot phase.
Otherwise there will be ACPI interrupt flood triggered by the GPE input.
The _PSW object is depreciated in ACPI 3.0 and is replaced by _DSW.
So it is necessary to call _DSW object first. Only when it is not
present will the _PSW object used.

commit 3620f2f2f3 sets the cid of
ACPI video/dock/bay device and leaves the hid empty.
As a result, "modalias" should export the cid for
devices which don't have a hid.
ACPI Video driver is not autoloaded with
commit 3620f2f2f3 applied.
"cat /sys/.../device:03(acpi video bus)/modalias" shows nothing.
ACPI Video driver is autoloaded after revert that commit.
"cat /sys/.../LNXVIDEO:0x/modalias" shows "acpi:LNXVIDEO:"
ACPI Video driver is autoloaded with commit
3620f2f2f3 and this patch applied.
"cat /sys/.../device:03(acpi video bus)/modalias"
shows "acpi:LNXVIDEO:"

When trying to get the acpi_handle from an acpi_buffer, pass
ACPI_ROOT_OBJECT instead of NULL to acpi_get_handle(). This fixes the
detection of dock dependent bays.

Due to the new autloading of acpi drivers, the dock driver
wasn't loaded anymore as there is no HID to identify it with
(dock is needed if ACPI has a _DCK method).
This patch is a workaround for this, original by Thomas Renninger,
revised first by Kay Sievers and last by Frank Seidel.
V2 of this patch fixed problems on systems without a defined _CID for
the docking devices.

This changes the uevent buffer functions to use a struct instead of a
long list of parameters. It does no longer require the caller to do the
proper buffer termination and size accounting, which is currently wrong
in some places. It fixes a known bug where parts of the uevent
environment are overwritten because of wrong index calculations.
Many thanks to Mathieu Desnoyers for finding bugs and improving the
error handling.

Modify modpost (file2alias.c) to add acpi*:XYZ0001: alias in modules.alias
like:
grep acpi /lib/modules/2.6.22-rc4-default/modules.alias
alias acpi*:SNY5001:* sony_laptop
alias acpi*:SNY6001:* sony_laptop
for e.g. the sony_laptop module.
This module matches against all ACPI devices with a HID or CID of SNY5001
or SNY6001
Export an uevent and modalias sysfs file containing the string:
[MODALIAS=]acpi:PNP0C0C:
additional CIDs are concatenated at the end.
