2406 | kexec is a system call that implements the ability to shutdown your | |

2463 | When this is enabled, the kernel will support use of 64-bit floating | |
2464 | point registers with binaries using the O32 ABI along with the | |
2465 | EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On | |
2466 | 32-bit MIPS systems this support is at the cost of increasing the | |
2467 | size and complexity of the compiled FPU emulator. Thus if you are | |
2468 | running a MIPS32 system and know that none of your userland binaries | |
2469 | will require 64-bit floating point, you may wish to reduce the size | |
2470 | of your kernel & potentially improve FP emulation performance by | |

2477 | be considered experimental and only enabled by those working upon | |
