	  since they have inadequate hardware support for multiprocessor

	  operation.

	  If you say N here, the kernel will run on single and multiprocessor

	  machines, but will use only one CPU of a multiprocessor machine. If

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

	  mean that extra synchronization instructions are required near

	  certain instructions, typically those that make major changes to the

	  CPU state.  These extra instructions reduce performance slightly.

	  If you say N here, these extra instructions will not be included,

	  resulting in a kernel which will run faster but may not run at all

	  on some systems with the PPC601 chip.

	  If in doubt, say Y here.

config TAU

	bool "Thermal Management Support"

	depends on 6xx

	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

	  and in some cases, does not work at all, so don't assume the cpu

	  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.

config TAU_AVERAGE

	bool "Average high and low temp"

	depends on TAU

	---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.

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

	  but it is indepedent of the system firmware.   And like a reboot

	  you can start any kernel with it, not just Linux.

	  The name comes from the similiarity to the exec system call.

	  It is an ongoing process to be certain the hardware in a machine

	  is properly shutdown, so do not be surprised if this code does not

	  initially work for you.  It may help to enable device hotplugging
