	  kexec is a system call that implements the ability to shutdown your
	  current kernel, and to start another kernel.  It is like a reboot
2854
	  but it is independent of the system firmware.   And like a reboot
2855 2856
	  you can start any kernel with it, not just Linux.

	  The name comes from the similarity to the exec system call.
2858 2859 2860

	  It is an ongoing process to be certain the hardware in a machine
	  is properly shutdown, so do not be surprised if this code does not
2861 2862 2863
	  initially work for you.  As of this writing the exact hardware
	  interface is strongly in flux, so no good recommendation can be
	  made.

	  When this is enabled, the kernel will support use of 64-bit floating

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

	  be considered experimental and only enabled by those working upon
	  said details.
