Add bindings to support LEDs defined as of_platform devices in addition to
the existing bindings for platform devices.
New options in Kconfig allow the platform binding code and/or the
of_platform code to be turned on. The of_platform code is of course only
available on archs that have OF support.
The existing probe and remove methods are refactored to use new functions
create_gpio_led(), to create and register one led, and delete_gpio_led(),
to unregister and free one led. The new probe and remove methods for the
of_platform driver can then share most of the common probe and remove code
with the platform driver.
The suspend and resume methods aren't shared, but they are very short. The
actual led driving code is the same for LEDs created by either binding.
The OF bindings are based on patch by Anton Vorontsov
<avorontsov@ru.mvista.com>. They have been extended to allow multiple LEDs
per device.

Enforce strict resource checking - disallowing access by native
drivers to IO ports and memory regions claimed by ACPI firmware.
The patch is mainly aimed to block native hwmon drivers from touching
monitoring chips that ACPI thinks it own.
If this causes a regression, boot with "acpi_enforce_resources=lax"
which was the previous default.

Refactor and redesign the brightness control backend...
In order to fix bugzilla #11750...
Add a new brightness control mode: support direct NVRAM checkpointing
of the backlight level (i.e. store directly to NVRAM without the need
for UCMS calls), and use that together with the EC-based control.
Disallow UCMS+EC, thus avoiding races with the SMM firmware.
Switch the models that define HBRV (EC Brightness Value) in the DSDT
to the new mode. These are: T40-T43, R50-R52, R50e, R51e, X31-X41.
Change the default for all other IBM ThinkPads to UCMS-only. The
Lenovo models already default to UCMS-only.

Enhance debugging messages for all rfkill subdrivers in thinkpad-acpi.
Also, log a warning if the deprecated sysfs attributes are in use.
These attributes are going to be removed sometime in 2010.
There is an user-visible side-effect: we now coalesce attempts to
enable/disable bluetooth or WWAN in the procfs interface, instead of
hammering the firmware with multiple requests.

Some of the ThinkPad LEDs indicate critical conditions that can cause
data loss or cause hardware damage when ignored (e.g. force-ejecting
a powered up bay; ignoring a failing battery, or empty battery; force-
undocking with the dock buses still active, etc).
On almost all ThinkPads, LED access is write-only, and the firmware
usually does fire-and-forget signaling on them, so you effectively
lose whatever message the firmware was trying to convey to the user
when you override the LED state, without any chance to restore it.
Restrict access to all LEDs that can convey important alarms, or that
could mislead the user into incorrectly operating the hardware. This
will make the Lenovo engineers less unhappy about the whole issue.
Allow users that really want it to still control all LEDs, it is the
unaware user that we have to worry about.

The HKEY disable functionality basically cripples the entire event
model of the ThinkPad firmware and of the thinkpad-acpi driver.
Remove this functionality from the driver. HKEY must be enabled at
all times while thinkpad-acpi is loaded, and disabled otherwise.
For sysfs, according to the sysfs ABI and the thinkpad-acpi sysfs
rules of engagement, we will just remove the attributes. This will be
done in two stages: disable their function now, after two kernel
releases, remove the attributes.
For procfs, we call WARN(). If nothing triggers it, I will simply
remove the enable/disable commands entirely in the future along with
the sysfs attributes.
I don't expect much, if any fallout from this. There really isn't any
reason to mess with hotkey_enable or with the enable/disable commands
to /proc/acpi/ibm/hotkey, and this has been true for years...

Add a debug helper that discloses the TGID of the userspace task
attempting to access the driver. This is highly useful when dealing
with bug reports, since often the user has no idea that some userspace
application is accessing thinkpad-acpi...
Also add a helper to log warnings about sysfs attributes that are
deprecated.
Use the new helpers to issue deprecation warnings for bluetooth_enable
and wwan_enabled, that have been deprecated for a while, now.

Fix the tracepoint documentation to refer to "tracepoint-sample"
instead of "tracepoint-example" to match what actually exists;
fix the directory, and clarify how to compile.
Change every instance of "example" in the sample tracepoint code
to "sample" for consistency.

from early boot tracing view, trace_buf_size parameter is important.
it should be documented.

Impact: clean up
The macros TPPROTO, TPARGS, TPFMT, TPRAWFMT, and TPCMD all look a bit
ugly. This patch adds an underscore to their names.

Use a more generic name - this also allows the prototype to move
to kernel.h and be generally available to kernel developers who
want to do some quick tracing.
