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

182 a kernel which includes all necessary drivers built-in and which can
183 be used for TFTP booting without the need to have an initrd ramdisk.
