  	help
  	  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).

  config SMP

  	default "6" if SMP
  	---help---
  	  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.
