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

139 This allows you to specify the maximum number of CPUs which this
140 kernel will support. The maximum supported value is 6 and the
141 minimum value which makes sense is 2.
142
143 This is purely to save memory - each supported CPU adds
144 approximately eight kilobytes to the kernel image.
