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

+         This allows you to specify the maximum number of CPUs which this
+         kernel will support.  The maximum supported value is 6 and the
+         minimum value which makes sense is 2.
+
+         This is purely to save memory - each supported CPU adds
