204 | depends on PA8X00 | |
205 | help | |
206 | If you configure the kernel to include many drivers built-in instead | |
207 | as modules, the kernel executable may become too big, so that the | |
208 | linker will not be able to resolve some long branches and fails to link | |
209 | your vmlinux kernel. In that case enabling this option will help you | |
210 | to overcome this limit by using the -mlong-calls compiler option. | |
211 | ||
212 | Usually you want to say N here, unless you e.g. want to build | |
213 | a kernel which includes all necessary drivers built-in and which can | |
214 | be used for TFTP booting without the need to have an initrd ramdisk. | |

226 | ||
227 | Since there is no 64bit userland on PA-RISC, there is no point to | |
228 | enable this option otherwise. The 64bit kernel is significantly bigger | |
