+	  When this is enabled, the kernel will support use of 64-bit floating
+	  point registers with binaries using the O32 ABI along with the
+	  EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
+	  32-bit MIPS systems this support is at the cost of increasing the
+	  size and complexity of the compiled FPU emulator. Thus if you are
+	  running a MIPS32 system and know that none of your userland binaries
+	  will require 64-bit floating point, you may wish to reduce the size
+	  of your kernel & potentially improve FP emulation performance by
+	  saying N here.
