   8           Generic Thermal Sysfs driver offers a generic mechanism for
   9           thermal management. Usually it's made up of one or more thermal
  10           zone and cooling device.
  11           Each thermal zone contains its own temperature, trip points,
  12           cooling devices.
  13           All platforms with ACPI thermal support can use this driver.
  14           If you want this support, you should say Y or M here.

  30           Thermal subsystem will issue a graceful shutdown when
  31           critical temperatures are reached using orderly_poweroff(). In
  32           case of failure of an orderly_poweroff(), the thermal emergency
  33           poweroff kicks in after a delay has elapsed and shuts down the system.
  34           This config is number of milliseconds to delay before emergency
  35           poweroff kicks in. Similarly to the critical trip point,
  36           the delay should be carefully profiled so as to give adequate
  37           time for orderly_poweroff() to finish on regular execution.
