-        bool "On-chip CPU temperature sensor support"

-        help
-          G3 and G4 processors have an on-chip temperature sensor called the
-          'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
-          temperature within 2-4 degrees Celsius. This option shows the current
-          on-die temperature in /proc/cpuinfo if the cpu supports it.
-
-          Unfortunately, on some chip revisions, this sensor is very inaccurate

-          temp is actually what /proc/cpuinfo says it is.

-config TAU_INT
-        bool "Interrupt driven TAU driver (DANGEROUS)"
-        depends on TAU
-        ---help---
-          The TAU supports an interrupt driven mode which causes an interrupt
-          whenever the temperature goes out of range. This is the fastest way
-          to get notified the temp has exceeded a range. With this option off,
-          a timer is used to re-check the temperature periodically.
-
-          However, on some cpus it appears that the TAU interrupt hardware
-          is buggy and can cause a situation which would lead unexplained hard
-          lockups.
-
-          Unless you are extending the TAU driver, or enjoy kernel/hardware
-          debugging, leave this option off.

-        bool "Average high and low temp"

-        ---help---
-          The TAU hardware can compare the temperature to an upper and lower
-          bound.  The default behavior is to show both the upper and lower
-          bound in /proc/cpuinfo. If the range is large, the temperature is
-          either changing a lot, or the TAU hardware is broken (likely on some
-          G4's). If the range is small (around 4 degrees), the temperature is
-          relatively stable.  If you say Y here, a single temperature value,
-          halfway between the upper and lower bounds, will be reported in
-          /proc/cpuinfo.

-          If in doubt, say N here.
