commit 27663c5855b10af9ec67bc7dfba001426ba21222 upstream
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.
lenb: replaced use of "acpi_integer" with "unsigned long long"
lenb: fixed bug in acpi_thermal_trips_update()

The following patch (based on a patch from Stephen Gildea) fixes a
regression with the LCD brightness keys on Fujitsu P8010 laptops which was
observed with the 2.6.27-rc series (basically they stopped working due to
changes within the fujitsu-laptop and video modules). Please apply to
2.6.27-rc and acpi git.
A more complete solution for this laptop will be included in an upcoming
patch, hopefully for 2.6.28. In the meantime this restores most
functionality for P8010 users.

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.
