As promised on Bugzilla I've tested v2 of this series (with the "INC"
manually fixed up) on a MacBookPro9,1.

I only reviewed the patches in a superficial fashion, but one issue I've
noticed is that

#define pr_fmt(fmt) "ACPI: " fmt

is missing in osi.c (patch [6/6]).

Without command line arguments, Linux responds yay to _OSI("Darwin")
and nothing else and the Thunderbolt controller is powered up.

With "acpi_osi=!Darwin", Linux responds nay to everything and the
Thunderbolt controller is powered down.

So it seems to work as intended. If you want me to test anything else
please let me know.

Thanks,

Lukas
