+ Newer laptops and tablets that use ACPI may have thermal sensors and
+ other devices with thermal control capabilities outside the core
+ CPU/SOC, for thermal safety reasons.
+ They are exposed for the OS to use via the INT3400 ACPI device object
+ as the master, and INT3401~INT340B ACPI device objects as the slaves.
+ Enable this to expose the temperature information and cooling ability
+ from these objects to userspace via the normal thermal framework.
+ This means that a wide range of applications and GUI widgets can show
+ the information to the user or use this information for making
+ decisions. For example, the Intel Thermal Daemon can use this
+ information to allow the user to select his laptop to run without
+ turning on the fans.
