Some new devices have extra keys, which we add to our list. Currently,
they all generate events that allow us to use a simple table/array,
without need for the sparse keymap.

The following build bug (x86, allyesconfig):
arch/x86/oprofile/built-in.o:(.data+0x250): multiple definition of `buffer_mutex'
Was triggered in -tip testing, caused by this upstream commit:
116ee77: dell-laptop: Use buffer with 32-bit physical address
There's multiple buffer_mutex's in the kernel. Make this new one

The asus-laptop driver implements a number of interfaces like the
backlight class driver. This change makes it easier to examine the
implementation of one interface at at a time, without having to search
through the file to find init() and exit() functions etc.

(Changelog stolen from Alan's patch for eeepc-laptop, but this patch
does the same thing for asus-laptop)
Callback methods should not refer to a variable like "asus" (formally
"hotk"). Instead, they should extract the data they need either from
a "driver data" parameter, or the "driver data" field of the object
which they operate on. The "asus" variable can then be removed.
In practice, drivers under "drivers/platform" can get away without using
driver data, because it doesn't make sense to have more than one
instance of them. However this makes it harder to review them for
correctness. This is especially true for core ACPI developers who have
not previously been exposed to this anti-pattern :-).
This will serve as an example of best practice for new driver writers
(whether they find it themselves, or have it pointed out during review
:-).

Before we mark the wireless device as unplugged, check PCI config space
to see whether the wireless device is really disabled (and vice versa).
This works around newer models which don't want the hotplug code, where
we end up disabling the wired network device.
My old 701 still works correctly with this. I can also simulate an
afflicted model by changing the hardcoded PCI bus/slot number in the
driver, and it seems to work nicely (although it is a bit noisy).
In future this type of hotplug support will be implemented by the PCI
core. The existing blacklist and the new warning message will be
removed at that point.

Clemens Ladisch reports that thinkpad-acpi improperly implements the
ALSA API, and always returns 0 for success for the "put" callbacks
while the API requires it to return "1" when the control value has
been changed in the hardware/firmware.
Rework the volume subdriver to be able to properly implement the ALSA
API. Based on a patch by Clemens Ladisch <clemens@ladisch.de>.
This fix is also needed on 2.6.33.

Given the right combination of ThinkPad and X.org, just reading the
video output control state is enough to hard-crash X.org.
Until the day I somehow find out a model or BIOS cut date to not
provide this feature to ThinkPads that can do video switching through
X RandR, change permissions so that only processes with CAP_SYS_ADMIN
can access any sort of video output control state.
This bug could be considered a local DoS I suppose, as it allows any
non-privledged local user to cause some versions of X.org to
hard-crash some ThinkPads.

Studying the DSDTs of various thinkpads, it looks like bit 3 of the
argument to SBDC and SWAN is not "set radio to last state on resume".
Rather, it seems to be "if this bit is set, enable radio on resume,
otherwise disable it on resume".
So, the proper way to prepare the radios for S3 suspend is: disable
radio and clear bit 3 on the SBDC/SWAN call to to resume with radio
disabled, and enable radio and set bit 3 on the SBDC/SWAN call to
resume with the radio enabled.
Also, for persistent devices, the rfkill core does not restore state,
so we really need to get the firmware to do the right thing.
We don't sync the radio state on suspend, instead we trust the BIOS to
not do anything weird if we never touched the radio state since boot.
Time will tell if that's a wise way of doing things...

Thadeu Lima de Souza Cascardo reports this:
Brightness notification does not work until the user writes to
hotkey_mask attribute. That's because the polling thread will only run
if hotkey_user_mask is set and someone is reading the input device or
if hotkey_driver_mask is set. In this second case, this condition is
not tested after the mask is changed, because the brightness and
volume drivers are started after the hotkey drivers.
Fix tpacpi_hotkey_driver_mask_set() to call hotkey_poll_setup(), so
that the poller kthread will be started when needed.

Event 0x3006 is used to help power management of the ODD in the
UltraBay. The EC generates this event when the ODD eject button is
pressed (even if the bay is powered down).
Normally, Linux doesn't need this as we keep the SATA link powered
up (which wastes power). The EC powers up the bay by itself when the
ODD eject button is pressed, and the SATA PHY reports the hotplug.
However, we could also power that SATA link down (and for that matter,
also power down the Ultrabay) if the ODD is left idle for a while with
no disk inside, and use event 0x3006 to know when we need that SATA link
powered back up.
For now, just stop asking for more information when event 0x3006 is
seen, there is no point in pestering users about it anymore.
