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

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