---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.
