fe06fba292 ACPI: dock: add struct dock_station * directly to platform device data
Instead of adding a (struct dock_station **) to our dock device's
platform data, we can add the (struct dock_station *) directly.

This change saves us some ugly casting and improves readability.

The cost of making this change is an extra 290 bytes of stack usage,
but this is an infrequently called code-path and unlikely to cause
the kernel to blow up.

15b8dd53f5 ACPICA: Major update for acpi_get_object_info external interface
Completed a major update for the acpi_get_object_info external interface.
Changes include:
 - Support for variable, unlimited length HID, UID, and CID strings
 - Support Processor objects the same as Devices (HID,UID,CID,ADR,STA, etc.)
 - Call the _SxW power methods on behalf of a device object
 - Determine if a device is a PCI root bridge
 - Change the ACPI_BUFFER parameter to ACPI_DEVICE_INFO.
These changes will require an update to all callers of this interface.
See the ACPICA Programmer Reference for details.

Also, update all invocations of acpi_get_object_info interface

f67f129e51 Driver core: implement uevent suppress in kobject
This patch implements uevent suppress in kobject and removes it
from struct device, based on the following ideas:

1,Uevent sending should be one attribute of kobject, so suppressing it
in kobject layer is more natural than in device layer. By this way,
we can do it for other objects embedded with kobject.

2,It may save several bytes for each instance of struct device.(On my
omap3(32bit ARM) based box, can save 8bytes per device object)

This patch also introduces dev_set|get_uevent_suppress() helpers to
set and query uevent_suppress attribute in case to help kobject
as private part of struct device in future.

[This version is against the latest driver-core patch set of Greg,please
ignore the last version.]

fc5a9f8841 ACPI: dock: Don't eval _STA on every show_docked sysfs read
Some devices trigger a DEVICE_CHECK on every evalutation of _STA. This
can also be seen in commit 8b59560a3b
(ACPI: dock: avoid check _STA method).  If an undock is processed, the
dock driver sends a uevent and userspace might read the show_docked
property in sysfs. This causes an evaluation of _STA of the particular
device which causes the dock driver to immediately dock again.

In any case, evaluation of _STA (show_docked) does not necessarily mean
that we are docked, so check with the internal device structure.

19cd847ab2 ACPI: fix hotplug race
The hotplug notification handler and drivers' notification handler all
run in one workqueue.  Before hotplug removes an acpi device, the
device driver's notification handler is already be recorded to run just
after global notification handler.  After hotplug notification handler
runs, acpica will notice a NULL notification handler and crash.

So now we run run hotplug in another workqueue and wait
for all acpi notication handlers finish.
This was found in battery hotplug, but actually all
hotplug can be affected.

Allow the driver to be loaded with an option that will allow userspace to
control whether the laptop is ejected immediately when the user presses the
button, or only when the syfs undock file is written.

if immediate_undock == 1, then when the user presses the undock button, the
laptop will send an event to userspace to notify userspace of the undock, but
then immediately undock without waiting for userspace.  This is the current
behavior, and I set this to be the default.

if immediate_undock == 0, then when the user presses the undock button, the
laptop will send an event to userspace and do nothing.  User space can query
the "flags" sysfs entry to determine if an undock request has been made by
the user (if bit 1 is set).  User space will then need to write the undock
sysfs entry to complete the undocking process.

ac122bb64b ACPI: dock: add access to ACPI docking station UID
It is useful to know whether your laptop is docked or not,
but it is even more useful to know which docking station it's
docked to. Attached patch adds "uid" file to sysfs.
Tested on Dell Latitude D600 with D/Dock.
Patch is against official 2.6.20 release.
