1270 | designed to be generic, i.e. Kernels compiled for R3000 CPUs will | |

2400 | kexec is a system call that implements the ability to shutdown your | |
2401 | current kernel, and to start another kernel. It is like a reboot | |
3dde6ad8 | 2402 | but it is independent of the system firmware. And like a reboot |

2403 | you can start any kernel with it, not just Linux. |

2457 | When this is enabled, the kernel will support use of 64-bit floating | |
2458 | point registers with binaries using the O32 ABI along with the | |
2459 | EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On | |
2460 | 32-bit MIPS systems this support is at the cost of increasing the | |
2461 | size and complexity of the compiled FPU emulator. Thus if you are | |
2462 | running a MIPS32 system and know that none of your userland binaries | |
2463 | will require 64-bit floating point, you may wish to reduce the size | |
2464 | of your kernel & potentially improve FP emulation performance by | |
