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

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