* 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6:
Merge branches 'release' and 'buildfix' into release
acer-wmi - Add documentation
sonypi - Move sonypi.txt to Documentation/laptops
sony-laptop - Move sony-laptop.txt to Documentation/laptops
thinkpad-acpi - Move thinkpad-acpi.txt to Documentation/laptops
Documentation - Create laptops sub-directory
ACPI: thermal: buildfix for CONFIG_THERMAL=n
cpuidle: build fix for non-x86
