2817	  kexec is a system call that implements the ability to shutdown your

2819	  but it is independent of the system firmware.   And like a reboot
2820	  you can start any kernel with it, not just Linux.
2821
2822	  The name comes from the similarity to the exec system call.
2823
2824	  It is an ongoing process to be certain the hardware in a machine
2825	  is properly shutdown, so do not be surprised if this code does not

2858	  This kernel feature is useful for number crunching applications

2861	  the process as file descriptors supporting the read/write

2865	  and the task is only allowed to execute a few safe syscalls

2873	help
2874	  When this is enabled, the kernel will support use of 64-bit floating
2875	  point registers with binaries using the O32 ABI along with the
2876	  EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2877	  32-bit MIPS systems this support is at the cost of increasing the
2878	  size and complexity of the compiled FPU emulator. Thus if you are
2879	  running a MIPS32 system and know that none of your userland binaries
2880	  will require 64-bit floating point, you may wish to reduce the size
2881	  of your kernel & potentially improve FP emulation performance by
2882	  saying N here.
2883
2884	  Although binutils currently supports use of this flag the details
2885	  concerning its effect upon the O32 ABI in userland are still being
2886	  worked on. In order to avoid userland becoming dependant upon current
2887	  behaviour before the details have been finalised, this option should
