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

	  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
2883 2884 2885
	  initially work for you.  As of this writing the exact hardware

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

	  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.
