2783	  but it is independent of the system firmware.   And like a reboot
2784	  you can start any kernel with it, not just Linux.
2785
2786	  The name comes from the similarity to the exec system call.
2787
2788	  It is an ongoing process to be certain the hardware in a machine
2789	  is properly shutdown, so do not be surprised if this code does not

2838	  When this is enabled, the kernel will support use of 64-bit floating
2839	  point registers with binaries using the O32 ABI along with the
2840	  EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2841	  32-bit MIPS systems this support is at the cost of increasing the
2842	  size and complexity of the compiled FPU emulator. Thus if you are
2843	  running a MIPS32 system and know that none of your userland binaries
2844	  will require 64-bit floating point, you may wish to reduce the size
2845	  of your kernel & potentially improve FP emulation performance by
2846	  saying N here.

2848	  Although binutils currently supports use of this flag the details
2849	  concerning its effect upon the O32 ABI in userland are still being
