Switch all task workers to a private thinkpad-acpi workqueue.
This way, we don't risk causing trouble for other tasks scheduled to the
default work queue, as our workers end up needing to access the ACPI EC,
run ACPI AML code, trigger SMI traps... and none of those are exactly known
to be fast, si
Fix a minor (nano?) thing that bothered me at exactly at the wrong time.

Unfortunately, a lot of stuff in the kernel has size limitations, so
"thinkpad-acpi" ends up eating up too much real estate. We were using
"tpacpi" in symbols already, but this shorthand was not visible to
userland.
Document that the driver will use tpacpi as a short hand where necessary,
and use
Add missing select for BACKLIGHT_LCD_SUPPORT, as select doesn't select the
dependencies of a symbol for us.
Also, "select INPUT" in Kconfig. We are not an Input device, nor are we
anywhere close to the input subsystem in the Kconfig tree, so using
"depends on INPUT" is not user-friendly at all.
Full LED sysfs support, and the rest of the assorted minor fixes and
enhancements are a good reason to checkpoint a new version...

ibm-acpi and thinkpad-acpi did not know about bit 5 of the EC backlight
level control register (EC 0x31), so it was always forced to zero on
any writes.
This would disable the BIOS option to *not* use a dimmer backlight level
scale while on battery, and who knows what else (there are two other

Lenovo ThinkPads with generic ACPI backlight level control can be easily
set to react to keyboard brightness key presses in a more predictable way
than what they do when in "DOS / bootloader" mode after Linux brings
up the ACPI interface.
The switch to the ACPI backlight mode in the firmware is de

If userspace applications mess with the CMOS NVRAM, or something causes
both the ACPI firmware and thinkpad-acpi to try to change the brightness at
the same time, it is possible to have the CMOS and EC registers for the
current brightness go out of sync.
Should that happen, thinkpad-acpi could be

Enhance those messages to output the alfanumeric model number as well.

Hello,
I have this ThinkPad and there is a few non-working features, such as
volume control via /proc/acpi/ibm/volume, also there is a problem with
weird acpi event when the lowest level of brightness is reached. But
