After XPC has been up and running on multiple partitions for any length of
time, if XPC on one of the partitions is stopped and restarted (either by
a rmmod/insmod or a system restart), it is possible for the XPCs running
on the other partitions to falsely detect a lack of heartbeat from the XPC
that was just restarted.  This false detection will occur if the restarted
XPC comes up within the five-seconds preceding one of the other XPC's
heartbeat check (which occurs once every twenty seconds).

The detection of no heartbeat results in the detecting XPC deactivating
from the just restarted XPC.  The only remedy is to restart one of the
XPCs and hope that one doesn't hit this five-second window on any of the
other partitions.

GBLS and GBLL only differ in the clearing of the GHKS flag, so there is no need
to have two backlight level readouts. Also, per Peter Gruber, the need for the
BLNF check has disappeared.
As a result, cleanups can be made in the code. This has been tested on the both
the S6410 and the S6420 platforms and causes no functionality regressions, on
the console without X or within X. One module parameter to disable the hotkeys
is dropped, as we only ever took one codepath anyway.

The FUNC interface in the Fujitsu-Siemens DSDT was unused until now. It exposes
state information that is now reported in additional platform files (whether the
radios are killed by the hardware switch or operational, whether the machine is
docked and whether the lid is open).
Support for the backlight class is now extended with the ability to power the
backlight on & off. Optional support for the LED class allows the keyboard
headlamps found on the U810 netbook and the Fujitsu logo illumination on the
P8010 notebook to be turned on & off.

This was fed through checkpatch.pl and tested on the S6420, P8010 & U810 platforms.

The community has been maintaining x86 vendor-specific
platform specific drivers under /drivers/misc/ for a few years.
The oldest ones started life under drivers/acpi.
They moved out of drivers/acpi/ because they don't actually

use ACPI, or implement vendor-specific ACPI extensions.

This fixes a regression from v2.6.27, caused by commit
5814f737e1cd2cfa2893badd62189acae3e1e1fd, "ACPI: thinkpad-acpi:
attempt to preserve fan state on resume".

It is possible for fan_suspend() to fail to properly initialize
fan_control_desired_level as required by fan_resume(), resulting on
the fan always being set to level 7 on resume if the user didn't
touch the fan controller.

In order to get fan sleep/resume handling to work right:

1. Fix the fan_suspend handling of the T43 firmware quirk. If it is
still undefined, we didn't touch the fan yet and that means we have no
business doing it on resume.

2. Store the fan level on its own variable to avoid any possible
issues with hijacking fan_control_desired_level (which isn't supposed
to have anything other than 0-7 in it, anyway).

3. Change the fan_resume code to me more straightforward to understand
(although we DO optimize the boolean logic there, otherwise it looks
disgusting).

4. Add comments to help understand what the code is supposed to be
doing.

5. Change fan_set_level to be less strict about how auto and
full-speed modes are requested.

I can't set brightness on my sony laptop (nothing in /sys/class/backlight).
dmesg says "sony-laptop: Sony: Brightness ignored, must be controlled by ACPI

The function acpi_video_backlight_support returns 0 if we should use the
vendor-specific backlight support, while non-0 if the ACPI generic should
be used. Because of this, the check introduced by the said commit appears
