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

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