2769	  When this is enabled, the kernel will support use of 64-bit floating
2770	  point registers with binaries using the O32 ABI along with the
2771	  EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2772	  32-bit MIPS systems this support is at the cost of increasing the
2773	  size and complexity of the compiled FPU emulator. Thus if you are
2774	  running a MIPS32 system and know that none of your userland binaries
2775	  will require 64-bit floating point, you may wish to reduce the size
2776	  of your kernel & potentially improve FP emulation performance by
2777	  saying N here.
2778
2779	  Although binutils currently supports use of this flag the details
2780	  concerning its effect upon the O32 ABI in userland are still being
2781	  worked on. In order to avoid userland becoming dependant upon current
2782	  behaviour before the details have been finalised, this option should
2783	  be considered experimental and only enabled by those working upon
2784	  said details.
