Add a debugfs file for showing the full results of the method we use to
detect devices on WMID laptops.

This should be useful in the case that a Linux user gets an Acer laptop
with 3G support (and/ or people who enjoy ripping their wireless cards out)
so we can get some feedback on how this value changes in these cases.

(At the moment, we always enable the wireless and 3G control. In the case
of the former, this is fairly safe. In the case of the latter though,
trying to toggle this device if it doesn't exist on a laptop causes ACPI
warnings/ errors).

To summarise: If you have an Acer laptop with a built in 3G card, please
report back the value from this file.

The AMW0 (V1) device detection method doesn't work properly on this laptop,
so disable it, and for other laptops that may have this problem, by
switching on a strange GUID.

A newer BIOS for these laptops adds ACPI-WMI support to them. However, it does
not add support for the backlight via the EC, and we have no way to detect
this on older machines, so blacklist it from them.

Implemented another change for the GPE disable. We now perform a
read-change-write of the enable register instead of simply writing out the
cached enable mask. This will prevent inadvertent enabling of GPEs if a rogue
GPE is received during initialization (before GPE handlers are installed.)

When echo some invalid values to /proc/acpi/processor/*/throttling,
there isn't any error info returned, on the contray, it sets
throttling value to some T* successfully, obviously, this is incorrect,
a correct way should be to let it fail and return error info.

This patch fixed the aforementioned issue, it also enables
/proc/acpi/processor/*/throttling to accept such values as 't0' and 'T0',
it also strictly limits /proc/acpi/processor/*/throttling only to accept
 "*", "t*" and "T*", "*" is the throttling state value the processor can
support, current, it is 0 - 7.

Before applying this patch, the test result is below:

Under /proc/acpi, there is a fan control interface, a user can
set 0 or 3 to /proc/acpi/fan/*/state, 0 denotes D0 state, 3
denotes D3 state, but in current implementation, a user can
set a fan to D1 state by any char excluding '1', '2' and '3'.

For example:

[root@localhost acpi]# cat /proc/acpi/fan/C31B/state
status:                  off
[root@localhost acpi]# echo "" > /proc/acpi/fan/C31B/state
[root@localhost acpi]# cat /proc/acpi/fan/C31B/state
status:                  on
[root@localhost acpi]# echo "3" > /proc/acpi/fan/C31B/state
[root@localhost acpi]# cat /proc/acpi/fan/C31B/state
status:                  off
[root@localhost acpi]# echo "xxxxx" > /proc/acpi/fan/C31B/state
[root@localhost acpi]# cat /proc/acpi/fan/C31B/state
status:                  on

Obviously, such inputs as "" and "xxxxx" are invalid for fan state.

This patch fixes this issue, it strictly limits fan state only to
accept 0, 1, 2 and 3, any other inputs are invalid.

Before applying this patch, the test result is:

[root@localhost acpi]# cat /proc/acpi/fan/C31B/state
status:                  off
[root@localhost acpi]# echo "" > /proc/acpi/fan/C31B/state
[root@localhost acpi]# cat /proc/acpi/fan/C31B/state

Add additional capabilities to the Fujitsu-laptop driver.

 * Brightness hotkey actions are sent to userspace. This can be disabled
   using a module parameter if it causes issues with models which handle
   these keys transparently in the BIOS.

 * Actions of additional hotkeys found on some Fujitsu models (eg: the
   suspend key and the dedicated "power on passphrase" keys) are broadcast
   to userspace.

 * An alternative brightness control method used by some Fujitsu models
   (for example, the S6410) is now supported, enabling software brightness
   controls on models using this method.

 * DMI-based module aliases are configured for the S6410 and S7020.

 * The current LCD brightness after booting should now be reflected in the
   standard backlight interface sysfs file (previously it was always set to
   0).  The platform brightness sysfs interface has always been fine.

Thanks go to Peter Gruber who provided a significant portion of this code
and tested various iterations of the patch on his S6410.

This is driver for Compal Laptop: FL90/IFL90, based on MSI driver.

This driver exports a few files in /sys/devices/platform/compal-laptop/:
 lcd_level - screen brightness: contains a single integer in the range 0..7 (rw)
 wlan - wlan subsystem state: contains 0 or 1 (rw)
 bluetooth - bluetooth subsystem state: contains 0 or 1 (rw)
 raw - raw value taken from embedded controller register (ro)

In addition to these platform device attributes the driver registers itself
in the Linux backlight control subsystem and is available to userspace under
/sys/class/backlight/compal-laptop/.

Sys I/F under acpi device node and sysdev device node are both
needed for cpu hot-removal. User space need this link so that
they know they are poking the sys I/F for the same cpu.

The ACPI device node for the cpu has already been unregistered
when acpi_processor_handle_eject is called.
Thus we should offline the cpu and continue, rather than a failure here.

"/sys/devices/LNXSYSTM:00/.../eject" is used to evaluate _EJx method
and eject a device in user space.
But system hangs when poking the "eject" file because that
the device hot-removal code invoke the driver .remove method which will
try to remove the "eject" file as a result.

Queues the hot-removal function for deferred execution in this patch.

Crosscompiling on a Fedora 9 machine running gcc 4.3.0 as its host compiler
and gcc 3.4.6 for the mips-linux target results in the following build
error:

$ make malta_defconfig
$ make
cc1: error: unrecognized command line option "-fno-stack-protector"
scripts/kconfig/conf -s arch/mips/Kconfig
cc1: error: unrecognized command line option "-fno-stack-protector"

The arch Makefile is included too late so the host compiler is feature
tested, not the crosscompiler as intended and thus the Makefile applies
adds -fno-stack-protector to crosscompiler's flags which fails for gcc
3.4.6.  The bug was introduced by e06b8b98
in 2.6.25; 35bb5b1e did add more flags
testing before the arch Makefile inclusion.
