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

165 This allows you to specify the maximum number of CPUs which this
166 kernel will support. The maximum supported value is 6 and the
167 minimum value which makes sense is 2.
168
169 This is purely to save memory - each supported CPU adds
170 approximately eight kilobytes to the kernel image.
