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

 123           This allows you to specify the maximum number of CPUs which this
 124           kernel will support.  The maximum supported value is 6 and the
 125           minimum value which makes sense is 2.
 126
 127           This is purely to save memory - each supported CPU adds
 128           approximately eight kilobytes to the kernel image.
