2782	  but it is independent of the system firmware.   And like a reboot
2783	  you can start any kernel with it, not just Linux.
2784
2785	  The name comes from the similarity to the exec system call.

2787	  It is an ongoing process to be certain the hardware in a machine
2788	  is properly shutdown, so do not be surprised if this code does not

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