	Due to poor thermal design or Linux driving hardware outside its thermal envelope, some systems will reach critical temperature and shut down under high load. This patch adds support for forcing a polling-based passive trip point if the firmware doesn't provide one. The assumption is made that the processor is the most practical means to reduce the dynamic heat generation, so hitting the passive thermal limit will cause the CPU to be throttled until the temperature stabalises around the defined value. UI is provided via a "passive" sysfs entry in the thermal zone directory. It accepts a decimal value in millidegrees celsius, or "0" to disable the functionality. Default behaviour is for this functionality to be disabled. Signed-off-by: Matthew Garrett <mjg@redhat.com> Signed-off-by: Len Brown <len.brown@intel.com>
2009-02-20	ACPI: move thermal trip handling to generic thermal layer	Matthew Garrett
	The ACPI code currently carries its own thermal trip handling, meaning that any other thermal implementation will need to reimplement it. Move the code to the generic thermal layer. Signed-off-by: Matthew Garrett <mjg@redhat.com> Signed-off-by: Len Brown <len.brown@intel.com>
2009-02-20	thermal: use integers rather than strings for thermal values	Matthew Garrett
	The thermal API currently uses strings to pass values to userspace. This makes it difficult to use from within the kernel. Change the interface to use integers and fix up the consumers.

2008-06-25	thermal: Create CONFIG_THERMAL_HWMON=n	Rene Herman
	A bug in libsensors <= 2.10.6 is exposed when this new hwmon I/F is enabled. Create CONFIG_THERMAL_HWMON=n until some time after libsensors 2.10.7 ships so those users can run the latest kernel. libsensors 3.x is already fixed -- those users can use CONFIG_THERMAL_HWMON=y now.

2008-04-29	thermal: re-name thermal.c to thermal_sys.c	Len Brown
	thermal_sys was already the name of the resulting module, and it is built from this one source file. Signed-off-by: Len Brown <len.brown@intel.com>
