2891 | kexec is a system call that implements the ability to shutdown your | |
2892 | current kernel, and to start another kernel. It is like a reboot | |
2893 | but it is independent of the system firmware. And like a reboot | |
2894 | you can start any kernel with it, not just Linux. | |
2895 | ||
2896 | The name comes from the similarity to the exec system call. | |
2897 | ||
2898 | It is an ongoing process to be certain the hardware in a machine | |
2899 | is properly shutdown, so do not be surprised if this code does not | |
2900 | initially work for you. As of this writing the exact hardware | |

2946 | help | |
2947 | When this is enabled, the kernel will support use of 64-bit floating | |
2948 | point registers with binaries using the O32 ABI along with the | |
2949 | EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On | |
2950 | 32-bit MIPS systems this support is at the cost of increasing the | |
2951 | size and complexity of the compiled FPU emulator. Thus if you are | |
2952 | running a MIPS32 system and know that none of your userland binaries | |
2953 | will require 64-bit floating point, you may wish to reduce the size | |
2954 | of your kernel & potentially improve FP emulation performance by | |
2955 | saying N here. | |

2957 | Although binutils currently supports use of this flag the details | |
2958 | concerning its effect upon the O32 ABI in userland are still being | |
