Len Brown considers that an active by default fan control interface in
laptops may be too close to giving users enough rope. There is a good
chance he is quite correct on this, especially if someone decides to use
that interface in applets and users are not aware of its risks.
This patch adds a master switch to thinkpad-acpi that enables or disables
the entire fan-control feature as a module parameter: "fan_control". It
defaults to disabled. Set it to non-zero to enable fan control.
Also, the patch removes the expermiental status from fan control, since it
is stable enough to not be called experimental, and the master switch makes
it safe enough to do so.

Update the brightness sysfs interface (done through the backlight class) to
be in line with the rest of the thinkpad-acpi driver.
This renames the incorrect, un-obvious, and clash-prone name of "ibm" for
the backlight device to a much more fitting and descriptive
"thinkpad_screen". This is something I wanted to do for quite a while...

Export sysfs attributes to monitor and control the internal thinkpad fan
(some thinkpads have more than one fan, but thinkpad-acpi doesn't support
the second fan yet). The sysfs interface follows the hwmon design guide
for fan devices.
Also, fix some stray "thermal" files in the fan procfs description that
have been there forever, and officially support "full-speed" as the name
for the PWM-disabled state of the fan controller to keep it in line with
the hwmon interface. It is much better a name for that mode than the
unobvious "disengaged" anyway. Change the procfs interface to also accept
full-speed as a fan level, but still report it as disengaged for backwards
compatibility.

Export thinkpad thermal sensors to sysfs, following the hwmon
specification for thermal monitoring sensors.
ThinkPad thermal monitoring is done by the EC. Sensors can show up or
disappear at runtime when they are inside hotswappable hardware, such as
batteries. Sensors that are not available return -ENXIO when accessed.
Up to 16 thermal sensors are supported on new firmware (but nobody has
reported a ThinkPad with more than 12 sensors so far), and 8 sensors are
supported on older firmware. Thermal sensor mapping is model-specific.
Precision varies, it is 1 degree Celcius on new ThinkPads, but higher on
some older models.

noreplacement is dangerous on modern systems because it will not replace the
context switch FNSAVE with SSE aware FXSAVE. But other places in the kernel still assume
SSE and do FXSAVE and the CPU will then access FXSAVE information with
FNSAVE and cause corruption.
Easiest way to avoid this is to remove the option. It was mostly for paranoia
reasons anyways and alternative()s have been stable for some time.

It seems that there must be at least one node in mems and at least one CPU
in cpus in order to be able to assign tasks to a cpuset. This makes sense.
And I think it would also make sense to include a mems setting in the
basic usage section of the documentation.
I also wonder if something logged to dmsg, explaining why a write failed,
would be a good enhancement. I ended up having rummage arround in cpuset.c
in order to work out why my configuration was failing.

Rename the ibm-acpi driver to thinkpad-acpi. ThinkPads are not even made
by IBM anymore, so it is high time to rename the driver...
The name thinkpad-acpi was used sometime ago by a thinkpad-specific hotkey
driver by Erik Rigtorp, around the 2.6.8-2.6.10 time frame. The driver
apparently never got merged into mainline (it did make some trips through
-mm). ibm-acpi was merged soon after, making its debut in 2.6.10.
The reuse of the thinkpad-acpi name shouldn't be a problem as far as user
confusion goes, as Erik's thinkpad-acpi apparently didn't get widespread
use in the Linux ThinkPad community and most hits for thinkpad-acpi in
google point to ibm-acpi anyway.
Erik, if you read this, please consider the reuse of the thinkpad-acpi name
as a compliment to your effort to make ThinkPads more useful to all of us.

It turned out that it is almost impossible to trust ACPI, BIOS & Co.
regarding the C states. This was the reason to switch the local apic
timer off in C2 state already. OTOH there are sane and well behaving
systems, which get punished by that decision.
Allow the user to confirm that the local apic timer is trustworthy in C2
state. This keeps the default behaviour on the safe side.

ACPI: IA64: fix %ll build warnings
ACPI: IA64: fix allnoconfig build
ACPI: Only use IPI on known broken machines (AMD, Dothan/BaniasPentium M)
ACPI: ibm-acpi: allow module to load when acpi notifiers can't be set (v2)
ACPI: parse 2nd MADT by default
ACPICA: revert "acpi_serialize" changes
sony-laptop: MAINTAINERS fix entry, add L: and W:
ACPI: resolve HP nx6125 S3 immediate wakeup regression
ACPI: Add support to parse 2nd MADT
The local APIC timer stops to work in deeper C-States. This is handled by
the ACPI code and a broadcast mechanism in the clockevents / tick managment
code.
Some systems do not expose the deeper C-States to the kernel, but switch
into deeper C-States behind the kernels back. This delays the local apic
timer interrupts for ever and makes the systems unusable.
Add a command line option to disable the local apic timer and a dmi
quirk for known broken systems.
Andi sayeth:
While not wrong by itself i think it is still better to use some heuristic
-- like "has battery in ACPI" With the DMI table if the problem is more wide
spread we will just continue extending it.
But anyways should be ok now for .21 although I'm not really happy with
it.

there is a tiny bug in Documentation/crypto/api-intro.txt.
The file has the following example code:
struct scatterlist sg[2];
[...]
if (crypto_hash_digest(&desc, &sg, 2, result))
which does not match the declaration of crypto_hash_digest() in
include/linux/crypto.h.
(static inline int crypto_hash_digest(struct hash_desc *desc,
struct scatterlist *sg, unsigned int nbytes, u8 *out)
The code in the example passes the address of a pointer (an array actually) as
the second argument, while the function expects the pointer itself.
I have attached a patch to fix this.

It's been pointed out that output GPIOs should have an initial value, to
avoid signal glitching ... among other things, it can be some time before
a driver is ready. This patch corrects that oversight, fixing
- documentation
- platforms supporting the GPIO interface
- users of that call (just one for now, others are pending)
There's only one user of this call for now since most platforms are still
using non-generic GPIO setup code, which in most cases already couples the
initial value with its "set output mode" request.
Note that most platforms are clear about the hardware letting the output
value be set before the pin direction is changed, but the s3c241x docs are
vague on that topic ... so those chips might not avoid the glitches.
