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
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
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.

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.

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.

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.

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.

Len,
This is a repost of the thinkpad-acpi queue. I sent it to you on
2008-11-22, but apparently it fell through the cracks...
The patchset was rebased to apply on top of 2.6.29-rc1.
Patches 1, 12 and 13 are new, but they are trivial.
Please, if at all possible, send it to Linus for 2.6.29 mer
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.

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 har
For your information:
Starting with Linux kernel 2.6.29-rc1, the ThinkPad-ACPI driver will
be in a new location in the kernel sources and configuration space.
The new kernel source directory is: drivers/platform/x86.
The documentation remains on Documentation/laptops/thinkpad-acpi.txt.
