[GIT PATCH v3.1] thinkpad-acpi changes for the merge window (part 1)

[Henrique de Moraes Holschuh <hmh@hmh.eng.br>]

Len,

Here is the third version (fixed) of the first batch of changes for
thinkpad-acpi, targetted at the next merge window.   They're mostly
non-critical fixes.

I have found a stupid bug on v2 and v2.1 of patch 6, and fixed it
(hopefully correctly, this time). I am *really* sorry about that.

I have also added two new patches, that were going to be sent as part 2,
but I might as well just send them in right now.

Patches 8 and 9 *fix* a big ABI problem with the way thinkpad-acpi was
exporting the hwmon attributes, which precluded it from working with
lm-sensors(!).  Since I am already touching the ABI, it also prepares
the thinkpad-acpi sensors ABI for a module split (so I can shunt all the
hwmon code to a new module later, and userspace won't even notice).

Please merge this batch to acpi-test.  It replaces previous versions of
"thinkpad-acpi changes for the merge window (part 1)".

As usual, the patch set is available at:
git://repo.or.cz/linux-2.6/linux-acpi-2.6/ibm-acpi-2.6.git for-upstream/acpi-test
