  	  If you configure the kernel to include many drivers built-in instead
  	  as modules, the kernel executable may become too big, so that the

  	  your vmlinux kernel. In that case enabling this option will help you
  	  to overcome this limit by using the -mlong-calls compiler option.
  
  	  Usually you want to say N here, unless you e.g. want to build
  	  a kernel which includes all necessary drivers built-in and which can
  	  be used for TFTP booting without the need to have an initrd ramdisk.
