	  On some platforms, there is currently no way for the boot loader
	  to pass arguments to the kernel. For these, you should supply some
	  command-line options at build time by entering them here.  At a
	  minimum, you should specify the memory size and the root device
	  (e.g., mem=64M root=/dev/nfs).

	  This allows you to specify the maximum number of CPUs which this
	  kernel will support.  The maximum supported value is 6 and the
	  minimum value which makes sense is 2.

	  This is purely to save memory - each supported CPU adds
	  approximately eight kilobytes to the kernel image.
