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

 152           This allows you to specify the maximum number of CPUs which this
 153           kernel will support.  The maximum supported value is 6 and the
 154           minimum value which makes sense is 2.
 155
 156           This is purely to save memory - each supported CPU adds
 157           approximately eight kilobytes to the kernel image.
