| 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 |
| approximately eight kilobytes to the kernel image. |
