	---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).
