2987597ce172SPaul Burton	  When this is enabled, the kernel will support use of 64-bit floating
2988597ce172SPaul Burton	  point registers with binaries using the O32 ABI along with the
2989597ce172SPaul Burton	  EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2990597ce172SPaul Burton	  32-bit MIPS systems this support is at the cost of increasing the
2991597ce172SPaul Burton	  size and complexity of the compiled FPU emulator. Thus if you are
2992597ce172SPaul Burton	  running a MIPS32 system and know that none of your userland binaries
2993597ce172SPaul Burton	  will require 64-bit floating point, you may wish to reduce the size
2994597ce172SPaul Burton	  of your kernel & potentially improve FP emulation performance by
2995597ce172SPaul Burton	  saying N here.
2996597ce172SPaul Burton
299706e2e882SPaul Burton	  Although binutils currently supports use of this flag the details
299806e2e882SPaul Burton	  concerning its effect upon the O32 ABI in userland are still being
299906e2e882SPaul Burton	  worked on. In order to avoid userland becoming dependant upon current
300006e2e882SPaul Burton	  behaviour before the details have been finalised, this option should
300106e2e882SPaul Burton	  be considered experimental and only enabled by those working upon
300206e2e882SPaul Burton	  said details.
