 237           Some versions of the PPC601 (the first PowerPC chip) have bugs which

 239           certain instructions, typically those that make major changes to the
 240           CPU state.  These extra instructions reduce performance slightly.
 241           If you say N here, these extra instructions will not be included,
 242           resulting in a kernel which will run faster but may not run at all

 251           G3 and G4 processors have an on-chip temperature sensor called the
 252           'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
 253           temperature within 2-4 degrees Celsius. This option shows the current
 254           on-die temperature in /proc/cpuinfo if the cpu supports it.
 255
 256           Unfortunately, on some chip revisions, this sensor is very inaccurate
 257           and in many cases, does not work at all, so don't assume the cpu
 258           temp is actually what /proc/cpuinfo says it is.

 263         ---help---
 264           The TAU supports an interrupt driven mode which causes an interrupt
 265           whenever the temperature goes out of range. This is the fastest way
 266           to get notified the temp has exceeded a range. With this option off,
 267           a timer is used to re-check the temperature periodically.
 268
 269           However, on some cpus it appears that the TAU interrupt hardware
 270           is buggy and can cause a situation which would lead unexplained hard
 271           lockups.

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