	  Loongson SIMD Extension (LSX) introduces 128 bit wide vector registers

	  and a set of SIMD instructions to operate on them. When this option

	  is enabled the kernel will support allocating & switching LSX

	  vector register contexts. If you know that your kernel will only be

	  running on CPUs which do not support LSX or that your userland will

	  not be making use of it then you may wish to say N here to reduce

	  the size & complexity of your kernel.

	  If unsure, say Y.
