	  Cause the compiler to optimize for the PPE of the Cell Broadband
	  Engine. This will make the code run considerably faster on Cell
	  but somewhat slower on other machines. This option only changes
	  the scheduling of instructions, not the selection of instructions
	  itself, so the resulting kernel will keep running on all other
	  machines. When building a kernel that is supposed to run only
	  on Cell, you should also select the POWER4_ONLY option.

	---help---
	  This option enables kernel support for larger than 32-bit physical
	  addresses.  This feature may not be available on all cores.

	  If you have more than 3.5GB of RAM or so, you also need to enable
	  SWIOTLB under Kernel Options for this to work.  The actual number
	  is platform-dependent.

	  If in doubt, say N here.

config ALTIVEC

	---help---
	  This option enables kernel support for the Altivec extensions to the
	  PowerPC processor. The kernel currently supports saving and restoring
	  altivec registers, and turning on the 'altivec enable' bit so user
	  processes can execute altivec instructions.

	  This option is only usefully if you have a processor that supports
	  altivec (G4, otherwise known as 74xx series), but does not have
	  any affect on a non-altivec cpu (it does, however add code to the
	  kernel).

	  If in doubt, say Y here.

config VSX
	bool "VSX Support"
	depends on POWER4 && ALTIVEC && PPC_FPU
	---help---

	  This option enables kernel support for the Vector Scaler extensions
	  to the PowerPC processor. The kernel currently supports saving and
	  restoring VSX registers, and turning on the 'VSX enable' bit so user
	  processes can execute VSX instructions.

	  This option is only useful if you have a processor that supports
	  VSX (P7 and above), but does not have any affect on a non-VSX
	  CPUs (it does, however add code to the kernel).

	  If in doubt, say Y here.

config SPE

	  This option is only useful if you have a processor that supports
	  SPE (e500, otherwise known as 85xx series), but does not have any

	help
	  Select this option to enable more accurate task and CPU time
	  accounting.  This is done by reading a CPU counter on each
	  kernel entry and exit and on transitions within the kernel
	  between system, softirq and hardirq state, so there is a
	  small performance impact.  This also enables accounting of
	  stolen time on logically-partitioned systems running on

	  This enables support for systems with more than one CPU. If you have

	  than one CPU, say Y.  Note that the kernel does not currently
	  support SMP machines with 603/603e/603ev or PPC750 ("G3") processors
	  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
	  you say Y here, the kernel will run on single-processor machines.
	  On a single-processor machine, the kernel will run faster if you say
	  N here.

	  If you don't know what to do here, say N.
