After a period of RFC for this driver, I think it is ready
for inclusion in the platform-driver-x86 tree, hopefully to
be staged in the next merge window into Linus's tree.

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.

The hdaps driver isn't a hardware monitoring driver, so it shouldn't

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).

Given the right combination of ThinkPad and X.org, just reading the
video output control state is enough to hard-crash X.org.
Until the day I somehow find out a model or BIOS cut date to not
provide this feature to ThinkPads that can do video switching through
X RandR, change permissions so that only processes with CAP_SYS_ADMIN
can access any sort of video output control state.
This bug could be considered a local DoS I suppose, as it allows any
non-privledged local user to cause some versions of X.org to
hard-crash some ThinkPads.

Allow the user to choose through Kconfig if the Console Audio Control

This not only saves some memory, but also allows the thinkpad-acpi
driver to be built-in even if ALSA is modular when the console audio
control interface is not wanted.
This change fixes a build problem that is causing some annoyances, in
a way that doesn't disable the entire driver on kernels without ALSA
support.

The standard ACPI dock driver can handle the hotplug bays and docks of
the ThinkPads just fine (including batteries) as of 2.6.27, and the
code in thinkpad-acpi for the dock and bay subdrivers is currently
broken anyway...
Userspace needs some love to support the two-stage ejection nicely,
but it is simple enough to do through udev rules (you don't even need
HAL) so this wouldn't justify fixing the dock and bay subdrivers,
either.
That leaves warm-swap bays (_EJ3) support for thinkpad-acpi, as well
as support for the weird dock of the model 570, but since such support
has never left the "experimental" stage, it is also not a strong
enough reason to find a way to fix this code.
Users of ThinkPads with warm-swap bays are urged to request that _EJ3
support be added to the regular ACPI dock driver, if such feature is
indeed useful for them.

Currently, the ThinkPad-ACPI bay and dock drivers are completely
broken, and cause a NULL pointer derreference in kernel mode (and,
therefore, an OOPS) when they try to issue events (i.e. on dock,
undock, bay ejection, etc).
OTOH, the standard ACPI dock driver can handle the hotplug bays and
docks of the ThinkPads just fine (including batteries) as of 2.6.27.
In fact, it does a much better job of it than thinkpad-acpi ever did.
It is just not worth the hassle to find a way to fix this crap without
breaking the (deprecated) thinkpad-acpi dock/bay ABI. This is old,
deprecated code that sees little testing or use.
As a quick fix suitable for -stable backports, mark the thinkpad-acpi
bay and dock subdrivers as BROKEN in Kconfig. The dead code will be
removed by a later patch.
This fixes bugzilla #13669, and should be applied to 2.6.27 and later.
