3003597ce172SPaul Burton	  When this is enabled, the kernel will support use of 64-bit floating
3004597ce172SPaul Burton	  point registers with binaries using the O32 ABI along with the
3005597ce172SPaul Burton	  EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
3006597ce172SPaul Burton	  32-bit MIPS systems this support is at the cost of increasing the
3007597ce172SPaul Burton	  size and complexity of the compiled FPU emulator. Thus if you are
3008597ce172SPaul Burton	  running a MIPS32 system and know that none of your userland binaries
3009597ce172SPaul Burton	  will require 64-bit floating point, you may wish to reduce the size
