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.

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.

Attempt to preserve fan state across sleep and hibernation if the fan
control mode is enabled.
For safety reasons, only the PWM OFF (fan at 100%) or maximum
closed-loop level (level 7) are preserved. If the fan state was set
to anything else, it will not be restored.
Also, should the fan be at PWM OFF mode at resume, it will be left at
that state (but this is extremely unlikely, no ThinkPad firmware was
ever reported to do this).
For reference, the known states used for fan control upon resume by
the firmware are either "auto" or "level 7" depending on whether the
laptop wakes due to normal conditions or a thermal emergency.

A few minor updates for the GRU driver.
- documentation changes found in code reviews
- changes to #ifdefs to make them recognized by "unifdef"
(used in simulator testing)
- change GRU context load/unload to prefetch data

Only three of Atmel's AT91 processors (SAM9263, SAM9RL and CAP9) include a
PWM controller.
It should therefore only be possible to enable the misc/atmel_pwm.c driver
on those processors (and not all AT91 processors).

EEEPC_LAPTOP uses RFKILL, so the former should depend on RFKILL.
Build errors happen when EEEPC_LAPTOP=y and RFKILL=m.

The kernel.h macro DIV_ROUND_UP performs the computation (((n) + (d) - 1) /
(d)) but is perhaps more readable.
An extract of the semantic patch that makes this change is as follows:

As of version 2.0, ACPI can return 64-bit integers. The current
acpi_evaluate_integer only supports 64-bit integers on 64-bit platforms.
Change the argument to take a pointer to an acpi_integer so we support
64-bit integers on all platforms.

This patch (mostly from Peter Gruber) improves the handling of the hotkeys
for P8010 laptops by passing more accurate input events back to userspace.
This is needed because the P8010 labels these buttons quite differently to
earlier laptops. As part of this, a P8010-specific DMI callback check has
been implemented. Finally there's some minor whitespace cleanups from
running the source through Lindent.

This patch implements rfkill support for the wireless and bluetooth devices
commonly found on Acer laptops.
For now, we will always poll these devices once a second to guarantee we
can catch state changes. On newer Acer laptops, it may be possible to rely
on WMI events to do this instead, and experimental support for this will be
added in a later patch.
3G has been deliberately left off for now, as we still have no way to
detect it, (nor, AFAIK, has any Linux user tried the code) and on laptops
that don't support 3G, trying to poll for the status will leave the logs
full of ACPI tracebacks.
The old sysfs interface for wireless and bluetooth will be removed in a
later patch.
(Thanks to Henrique de Moraes Holschuh and Dmitry Torokhov for reviewing
this patch).
