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).

This patch adds support for the ACPI events generated by the RFKill
switch on modern Toshiba laptops, and re-enables the Bluetooth USB
device when the switch is flipped back to the 'on' position.

The RFKill switch brute force pulls out the USB device when flipped to
'off', but it doesn't automatically re-enable it. Without this driver,
the Bluetooth is gone until after a reboot on my Portege R500.

This adds Topstar Laptop Extras ACPI driver. It enables hotkeys
functionality with Topstar N01 netbook. Besides hotkeys there are
other functions exposed by its ACPI firmware, but for now only
hotkeys reporting on Topstar N01 is supported. Topstar is a chinese
manufacturer, its website can be currently reached at

Move x86 platform specific drivers from drivers/misc/
to a new home under drivers/platform/x86/.

The community has been maintaining x86 vendor-specific
platform specific drivers under /drivers/misc/ for a few years.
The oldest ones started life under drivers/acpi.
They moved out of drivers/acpi/ because they don't actually
implement the ACPI specification, but either simply
use ACPI, or implement vendor-specific ACPI extensions.

In the future we anticipate...
drivers/misc/ will go away.
other architectures will create drivers/platform/<arch>
