404 G3 and G4 processors have an on-chip temperature sensor called the
405 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
406 temperature within 2-4 degrees Celsius. This option shows the current
407 on-die temperature in /proc/cpuinfo if the cpu supports it.
408
409 Unfortunately, on some chip revisions, this sensor is very inaccurate

417 The TAU supports an interrupt driven mode which causes an interrupt
418 whenever the temperature goes out of range. This is the fastest way
419 to get notified the temp has exceeded a range. With this option off,
420 a timer is used to re-check the temperature periodically.
421
422 However, on some cpus it appears that the TAU interrupt hardware
423 is buggy and can cause a situation which would lead unexplained hard
424 lockups.

427 debugging, leave this option off.

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

504 kexec is a system call that implements the ability to shutdown your

507 you can start any kernel with it, not just Linux.
508
509 The name comes from the similiarity to the exec system call.

511 It is an ongoing process to be certain the hardware in a machine
512 is properly shutdown, so do not be surprised if this code does not
513 initially work for you. It may help to enable device hotplugging

627 This kernel feature is useful for number crunching applications

631 syscalls, it's possible to isolate those applications in
632 their own address space using seccomp. Once seccomp is
