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

131 | This is purely to save memory - each supported CPU adds | |
132 | approximately eight kilobytes to the kernel image. | |
