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

  101. This allows you to specify the maximum number of CPUs which this
  102. kernel will support. The maximum supported value is 6 and the
  103. minimum value which makes sense is 2.
  104. This is purely to save memory - each supported CPU adds
  105. approximately eight kilobytes to the kernel image.
