200 | help | |
201 | If you configure the kernel to include many drivers built-in instead | |
202 | as modules, the kernel executable may become too big, so that the | |
203 | linker will not be able to resolve some long branches and fails to link | |
204 | your vmlinux kernel. In that case enabling this option will help you | |
205 | to overcome this limit by using the -mlong-calls compiler option. | |
206 | ||
207 | Usually you want to say N here, unless you e.g. want to build | |
208 | a kernel which includes all necessary drivers built-in and which can | |
209 | be used for TFTP booting without the need to have an initrd ramdisk. | |
