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.

Add missing log levels in a standalone commit, to avoid dependencies in
future unrelated changes, just because they wanted to use one of the
missing log levels.

Fix the vdbg_printk macro definition to be sane when
CONFIG_THINKPAD_ACPI_DEBUG is undefined, and move the mess into a file
section of its own.
This doesn't change anything in the current code, but future code will
need the proper behaviour.

The driver was renamed two years ago, on 2.6.21. Drop the old
compatibility alias, we have given everybody quite enough time
to update their configs to the new name.

Looking at the source, there seems to be a missing * to match my DMI
string. I mean for newer IBM and Lenovo's laptops you match either one
of the following:
MODULE_ALIAS("dmi:bvnIBM:*:svnIBM:*:pvrThinkPad*:rvnIBM:*");
MODULE_ALIAS("dmi:bvnLENOVO:*:svnLENOVO:*:pvrThinkPad*:rvnLENOVO:*");
While for older Thinkpads, you do this (for instance):
IBM_BIOS_MODULE_ALIAS("1[0,3,6,8,A-G,I,K,M-P,S,T]");
with IBM_BIOS_MODULE_ALIAS being MODULE_ALIAS("dmi:bvnIBM:bvr" __type "ET??WW")
Note there's no * terminating the string. As result, udev doesn't load
anything because modprobe cannot find anything matching this (my
machine actually):
udevtest: run: '/sbin/modprobe dmi:bvnIBM:bvr1IET71WW(2.10):bd06/16/2006:svnIBM:pn236621U:pvrNotAv

It is about time to bump up the version.
Features added since 0.21: fan suspend/resume support, preserve radio
state across power off (for some radio types), built-in UWB radio
rfkill support and thermal alarm events support.

HKEY event 0x6030 is a helper for Lenovo's Advanced Thermal Management
Windows driver, which is, of course, completely undocumented.
Silence any warnings about it being an unknown alarm, and report it
unmodified for userspace.

Better document the Unitialized HFSP quirk, and modularize it a bit.
This makes the code flow easier to read and reduces LOC.
Apply the Unitialized HFSP closer to the source (i.e. inside the
get_fan_status()), this fixes a harmless buglet where at driver init
with the quirk active, the user could set the hwmon pwm1 attribute and
switch out of pwm1_mode=2 to pwm1_mode=0 without changing pwm1_mode
directly.

Handle some HKEY events that are actually firmware alarms. For
now, we do the simple thing: log specific messages to the log and let
the thinkpad-specific event pass to userspace.
In the future, these events will be migrated to generic notifications
and subsystems.
These alarms are NOT available on all ThinkPads. E.g. the T43 only
issues 0x6011 and 0x6012.

Clean up the hotkey_notify() handler, which handles the HKEY notifications
from the ACPI firmware. It was getting too long and deep.
No functional changes.

Unfortunately, POSIX in all of its braindamage, do not state that userspace has
to deal with EINTR in read/write and friends... so, lesser code just doesn't.
Switch from *_interruptible to *_killable on the sysfs- and procfs-related
mutexes. This closes this possible can of worms.

Add rfkill support for USB UWB radio devices on very recent ThinkPad
laptop models.
The new subdriver is moslty a trimmed down copy of the wwan subdriver.

Store in firmware NVRAM the radio state on machine shutdown for WWAN and
bluetooth. Also, try to set the initial boot state of these radios as the
rfkill default state for their respective classes.

Instruct the firmware to not enable the radios when resuming. This
is safer, and the rfkill core will take care to manually enable any
radios that need to be enabled.

This code is required to keep the thinkpad-acpi maintainer sane, and
it is disabled by default.
Add a debug facility to simulate an rfkill hardware rocker switch, a
bluetooth rfkill soft-switch, a WWAN rfkill soft-switch on thinkpads.
The simulated switches obviously do not kill any radios in hardware or
firmware (unlike the real one). They also don't issue deprecated proc
events.

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>
