| 183 | If you configure the kernel to include many drivers built-in instead |
| 184 | as modules, the kernel executable may become too big, so that the |
| 185 | linker will not be able to resolve some long branches and fails to link |
| 186 | your vmlinux kernel. In that case enabling this option will help you |
| 187 | to overcome this limit by using the -mlong-calls compiler option. |

| 190 | a kernel which includes all necessary drivers built-in and which can |
