ACPI: fix processor throttling set error
http://bugzilla.kernel.org/show_bug.cgi?id=9704
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.

ACPI: fix acpi fan state set error
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

[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.

Fujitsu-laptop update
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.

Fix MIPS cross-compile problem
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
e06b8b98da071f7dd78fb7822991694288047df0
in 2.6.25;
35bb5b1e0e84cfa1a8906f7e6a77f391ff315791 did add more flags
