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

116 This allows you to specify the maximum number of CPUs which this
117 kernel will support. The maximum supported value is 6 and the
118 minimum value which makes sense is 2.
119
120 This is purely to save memory - each supported CPU adds
121 approximately eight kilobytes to the kernel image.
