Add support for keyboard backlight found in Asus U50VG.
The SMC driver for the Apples does it via LED. To be
consistent with that we create /sys/class/leds/asus::kbd_backlight/
to control the keyboard backlight.
SLKB and GLKB are used to get/set the backlight. On
the U50VG is supports 4 brightness level, but this may
change with other models.
SLKB take a 8 bit integer where the higher bit is used
to toggle the backlight, and the over 7 bits control the
brightness level.

This also involves switching the resume handler from the acpi device
to the platform device. Using the more fine grained handlers allows
two improvements:
1. We only need to recheck rfkill state after resume from hibernation.
2. The wireless LED workaround accounts for up to 1.1s out of 1.7s
resuming devices (when wireless is enabled). We can limit the
workaround to thaw(), so that it only delays suspend to disk.
The workaround is only likely to help when hibernation is aborted.
Suspend to ram cannot be aborted by the user. Device suspend errors may
well happen before eeepc-laptop would even be frozen. Suspend errors
which happen after that could be pretty funky anyway.

Sysfs showed the ehotk input device as a "virtual" device - lies!
The input device is provided by a physical device, the eeepc platform.
This requires that we move the creation of the input device to come
after platform device is created. Input initialization is moved from
ehotk_check() [sic] to a new function called eeepc_input_init(). This
brings the input device into line with the other eeepc-laptop devices.
Also, refuse to load if we fail to register the input device.

1. input and backlight devices were registered after acpi notifications
are enabled. This left a window where eeepc_hotk_notify() might
find these devices in an inconsistent (half-initialized) state.
-> Move all device registration into eeepc_hotk_add(), which is called
before enabling acpi notifications.
2. input and backlight devices were unregistered before acpi
notifications are disabled. This left a window where
eeepc_hotk_notify() might find these devices in an inconsistent
(half-destroyed) state.
-> Move all device unregistration into eeepc_hotk_remove(), which is
called after disabling acpi notifications.
3. The acpi driver was not freed if an error occured further down in
eeepc_laptop_init().
-> The rest of eeepc_laptop_init() has been moved to eeepc_hotk_add(),
so this is no longer a problem.
4. The acpi driver was unregistered before the platform driver. This
left a window where a sysfs access could attempt to read the ehotk
structure after it had been freed by eeepc_hotk_remove().
-> The acpi driver is now unregistered as the last step in
eeepc_laptop_exit(), so this is no longer a problem.

Wifi rfkill state changes can race with pci hotplug cleanup. A simple
fix is to refresh the hotplug state just before deregistering the pci
hotplug slot.
There is also potential for a hotplug notification to fire too early
during setup, while the structures it uses are still being initialised.
(This could only happen if the BIOS performs hotplug itself; a bug
triggered by removing the battery while hibernated). Avoid this by
registering the notifier later. The same refresh mechanism is used
to handle rfkill state changes which can now race with registration.

Commit d0265f0 "eeepc-laptop: fix hot-unplug on resume" used a workqueue
to protect pci hotplug against multiple simultaneous calls during
resume. It seems to work, but a mutex would be more appropriate.
This is in preparation to fix the potential pci hotplug race on unload.

The whole point of registering as a PCI hotplug driver was to prevent
conflict with pciehp. At the moment it happens to work because
eeepc-laptop is loaded first, but it doesn't work the other way round.
If pciehp is loaded first then we fail to claim the slot - we need to
respect this and not handle hotplug events.

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

Summary:
Kernel panic arise when stack protection is enabled, since strncat will
add a null terminating byte '\0'; So in functions
like this one (wmi_query_block):
char wc[4]="WC";
....
strncat(method, block->object_id, 2);
...
the length of wc should be n+1 (wc[5]) or stack protection
fault will arise. This is not noticeable when stack protection is
disabled,but , isn't good either.

OOPS on resume when the wireless adaptor is disabled during suspend was
introduced by "eeepc-laptop: read rfkill soft-blocked state on resume".
Unable to handle kernel NULL pointer dereference
Process s2disk
Tainted: G W
IP: klist_put
Call trace:
? klist_del
? device_del
? device_unregister
? pci_stop_dev
? pci_stop_bus
? pci_remove_device
? eeepc_rfkill_hotplug [eeepc_laptop]
? eeepc_hotk_resume [eeepc_laptop]
? acpi_device_resume
? device_resume
? hibernation_snapshot
It appears the PCI device is removed twice. The eeepc_rfkill_hotplug()
call from the resume handler is racing against the call from the ACPI
notifier callback. The ACPI notification is triggered by the resume
handler when it refreshes the value of CM_ASL_WLAN.
The fix is to serialize hotplug calls using a workqueue.

HBRV-based default selection of backlight control strategy didn't work
well, at least the X41 defines it but doesn't use it and I don't think
it will stop there.
Switch to a white/blacklist. All models that have HBRV defined have
been included in the list, and initially all ATI GPUs will get
ECNVRAM, and the Intel GPUs will get UCMS_STEP.
Symptoms of incorrect backlight mode selection are:
1. Non-working backlight control through sysfs;
2. Backlight gets reset to the lowest level at every shutdown, reboot
and when thinkpad-acpi gets unloaded;
This fixes a regression in 2.6.30, bugzilla #13826

The standard ACPI dock driver can handle the hotplug bays and docks of
the ThinkPads just fine (including batteries) as of 2.6.27, and the
code in thinkpad-acpi for the dock and bay subdrivers is currently
broken anyway...
Userspace needs some love to support the two-stage ejection nicely,
but it is simple enough to do through udev rules (you don't even need
HAL) so this wouldn't justify fixing the dock and bay subdrivers,
either.
That leaves warm-swap bays (_EJ3) support for thinkpad-acpi, as well
as support for the weird dock of the model 570, but since such support
has never left the "experimental" stage, it is also not a strong
enough reason to find a way to fix this code.
Users of ThinkPads with warm-swap bays are urged to request that _EJ3
support be added to the regular ACPI dock driver, if such feature is
indeed useful for them.

Currently, the ThinkPad-ACPI bay and dock drivers are completely
broken, and cause a NULL pointer derreference in kernel mode (and,
therefore, an OOPS) when they try to issue events (i.e. on dock,
undock, bay ejection, etc).
OTOH, the standard ACPI dock driver can handle the hotplug bays and
docks of the ThinkPads just fine (including batteries) as of 2.6.27.
In fact, it does a much better job of it than thinkpad-acpi ever did.
It is just not worth the hassle to find a way to fix this crap without
breaking the (deprecated) thinkpad-acpi dock/bay ABI. This is old,
deprecated code that sees little testing or use.
As a quick fix suitable for -stable backports, mark the thinkpad-acpi
bay and dock subdrivers as BROKEN in Kconfig. The dead code will be
removed by a later patch.
This fixes bugzilla #13669, and should be applied to 2.6.27 and later.

Some systems may not support input events, or registering the input
handler may have failed. So check that an input device exists before
trying to set the docking and tablet mode state during resume.

The eee contains a logically (but not physically) hotpluggable PCIe slot.
Currently this is handled by adding or removing the PCI device in response
to rfkill events, but if a user has forced pciehp to bind to it (with the
force=1 argument) then both drivers will try to handle the event and
hilarity (in the form of oopses) will ensue. This can be avoided by having
eee-laptop register the slot as a hotplug slot. Only one of pciehp and
eee-laptop will successfully register this, avoiding the problem.
