The serio ports on i8042 are not completely isolated; while we provide
enough locking to ensure proper serialization when accessing control
and data registers AUX and KBD ports can still have an effect on each
other on PS/2 protocol level. The most prominent effect is that
issuing a command for the device connected to one port may cause
abort of the command currently executing by the device connected to
another port.
Since i8042 nor serio subsystem are not aware of the details of the
PS/2 protocol (length of the commands and their replies and so on) the
locking should be done on libps2 level by adding special handling when
we see that we are dealing with serio port on i8042.

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

This adds Topstar Laptop Extras ACPI driver. It enables hotkeys
functionality with Topstar N01 netbook. Besides hotkeys there are
other functions exposed by its ACPI firmware, but for now only
hotkeys reporting on Topstar N01 is supported. Topstar is a chinese
manufacturer, its website can be currently reached at

Report KEY_BRIGHTNESSUP and KEY_BRIGHTNESSDOWN input events when the
ThinkPad is in "passive brightness control" mode (because either we or
ACPI video touched _BCL), and ACPI video is not processing these
events by itself.
This happens only on Lenovo ThinkPads with ACPI video support, when
operating with the ACPI video driver in acpi_backlight=vendor mode.
Issuing these events is the right thing to do, and will work around
bugzilla #13368, if userspace is properly configured and actively
handles these events.
For other ThinkPads, and when ACPI video is handling brightness
changes, thinkpad-acpi will continue NOT sending KEY_BRIGHTNESS*
events by default.

Init hotkey_source_mask late, so that we can make use of
hotkey_reserved_mask to avoid polling any of the reserved
hotkeys by default.

echo "reset" > /proc/acpi/ibm/hotkey should do something non-useless,
so instead of setting it to Fn+F2, Fn+F3, Fn+F5, set it to
hotkey_recommended_mask.
It is not like it will survive for much longer, anyway.

Some analysis of the ACPI DSDTs shows that the HKEY pre-enabled mask
is always 0x80c (FN+F3,FN+F4 and FN+F12), which are the hotkeys that
the second gen of HKEY firmware supported (the first gen didn't report
any hotkeys, the second reported these tree hotkeys but had no mask
support, and the third added mask support).
So, this is probably some sort of backwards compatibility with older
versions of the IBM ThinkVantage suite. We have no use for that, and
I know of exactly ZERO users of that attribute, anyway. Start the
process of getting rid of it.

Fix some locking, avoid exiting the kthread before kthread_stop() is
called on it, and clean up the hotkey poll routines a little bit.
Also, restore bits in the firmware mask after hotkey_source_mask is
changed. Without this, we leave events disabled...
