It should depend on the INPUT subsystem being present and select
INPUT_SPARSEKMAP so that those interfaces are present.

Introduce a new driver for Asus Notebooks shipped with
a WMI device instead of the old ACPI device. The WMI
device is almost the same as the one present in Eee PC,
but the event guid and the keymap are different.

The keymap comes from asus-laptop module.

On Asus notebooks, when you call the WMI device, you always
need a 64bit buffer, even if you only want to get the state
of a device (tested on a G73).

New Asus notebooks are using a WMI device similar to
the one used in Eee PCs. Since we don't want to load
eeepc-wmi module on Asus notebooks, and we want to
keep the eeepc-wmi module for backward compatibility,
this patch introduce a new module, named asus-wmi, that
will be used by eeepc-wmi and the new Asus Notebook WMI
Driver.

eeepc-wmi's input device strings (device name and phys)
are kept, but rfkill and led names are changed (s/eeepc/asus/).
This should not break anything since rfkill are used by type or
index, not by name, and the eeepc::touchpad led wasn't working
correctly before 2.6.39 anyway.

Currently the x86 platform devices are not consistent about selecting
or depending on the LEDs Kconfig variables, and this inconsistency
leads to Kconfig getting upset and refusing to offer LEDs (even on
non-x86 platforms):

IBM Real-Time "SMI Free" mode driver

This driver supports the Real-Time Linux (RTL) BIOS feature.
The RTL feature allows non-fatal System Management Interrupts
(SMIs) to be disabled on supported IBM platforms and is
intended to be coupled with a user-space daemon to monitor
the hardware in a way that can be prioritized and scheduled
to better suit the requirements for the system.

The Device is presented as a special "_RTL_" table to the OS
in the Extended BIOS Data Area.  There is a simple protocol
for entering and exiting the mode at runtime.  This driver
creates a simple sysfs interface to allow a simple entry and
exit from RTL mode in the UFI/BIOS.

Since the driver is specific to IBM SystemX hardware (x86-
based servers) it only builds on x86 builds.  To reduce the
risk of loading on the wrong hardware, the module uses DMI
information and checks a list of servers that are known to
work.

Don't ask how ACPI_TOSHIBA got enabled on in desktop system's .config -
I don't know.  But it has silently been there until I tried 2.6.36-rc2,
where it broke the build because I don't have LED support turned on.
Attached patch fixes things up.

(I had to change BACKLIGHT_CLASS_DEVICE to "depends" because otherwise
I get unsightly core dumps out of scripts/kconfig/conf).

Intel Core i3/5 platforms with integrated graphics support both CPU and
GPU turbo mode.  CPU turbo mode is opportunistic: the CPU will use any
available power to increase core frequencies if thermal headroom is
available.  The GPU side is more manual however; the graphics driver
must monitor GPU power and temperature and coordinate with a core
thermal driver to take advantage of available thermal and power headroom
in the package.

The intelligent power sharing (IPS) driver is intended to coordinate
this activity by monitoring MCP (multi-chip package) temperature and
power, allowing the CPU and/or GPU to increase their power consumption,
and thus performance, when possible.  The goal is to maximize
performance within a given platform's TDP (thermal design point).
