2831	  kexec is a system call that implements the ability to shutdown your

2833	  but it is independent of the system firmware.   And like a reboot
2834	  you can start any kernel with it, not just Linux.
2835
2836	  The name comes from the similarity to the exec system call.
2837
2838	  It is an ongoing process to be certain the hardware in a machine
2839	  is properly shutdown, so do not be surprised if this code does not

2871	  This kernel feature is useful for number crunching applications

2873	  execution. By using pipes or other transports made available to
2874	  the process as file descriptors supporting the read/write
2875	  syscalls, it's possible to isolate those applications in
2876	  their own address space using seccomp. Once seccomp is
2877	  enabled via /proc/<pid>/seccomp, it cannot be disabled
2878	  and the task is only allowed to execute a few safe syscalls

2886	help
2887	  When this is enabled, the kernel will support use of 64-bit floating
2888	  point registers with binaries using the O32 ABI along with the
2889	  EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2890	  32-bit MIPS systems this support is at the cost of increasing the
2891	  size and complexity of the compiled FPU emulator. Thus if you are
2892	  running a MIPS32 system and know that none of your userland binaries
2893	  will require 64-bit floating point, you may wish to reduce the size
2894	  of your kernel & potentially improve FP emulation performance by
2895	  saying N here.
2896
2897	  Although binutils currently supports use of this flag the details
2898	  concerning its effect upon the O32 ABI in userland are still being
2899	  worked on. In order to avoid userland becoming dependant upon current
2900	  behaviour before the details have been finalised, this option should
2901	  be considered experimental and only enabled by those working upon
2902	  said details.
