+ When this is enabled, the kernel will support use of 64-bit floating

+ 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.
+
+ Although binutils currently supports use of this flag the details
+ concerning its effect upon the O32 ABI in userland are still being
+ worked on. In order to avoid userland becoming dependant upon current
+ behaviour before the details have been finalised, this option should
+ be considered experimental and only enabled by those working upon
