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

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