2454 When this is enabled, the kernel will support use of 64-bit floating

2456 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2457 32-bit MIPS systems this support is at the cost of increasing the
2458 size and complexity of the compiled FPU emulator. Thus if you are
2459 running a MIPS32 system and know that none of your userland binaries

2461 of your kernel & potentially improve FP emulation performance by
