2433 When this is enabled, the kernel will support use of 64-bit floating
2434 point registers with binaries using the O32 ABI along with the
2435 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2436 32-bit MIPS systems this support is at the cost of increasing the
2437 size and complexity of the compiled FPU emulator. Thus if you are
2438 running a MIPS32 system and know that none of your userland binaries
2439 will require 64-bit floating point, you may wish to reduce the size
2440 of your kernel & potentially improve FP emulation performance by
