180 | depends on PA8X00 | |
181 | help | |
182 | If you configure the kernel to include many drivers built-in instead | |
183 | as modules, the kernel executable may become too big, so that the | |
184 | linker will not be able to resolve some long branches and fails to link | |
185 | your vmlinux kernel. In that case enabling this option will help you | |
186 | to overcome this limit by using the -mlong-calls compiler option. | |
187 | ||
188 | Usually you want to say N here, unless you e.g. want to build | |
189 | a kernel which includes all necessary drivers built-in and which can | |
190 | be used for TFTP booting without the need to have an initrd ramdisk. | |

192 | Enabling this option will probably slow down your kernel. | |

202 | ||
203 | Since there is no 64bit userland on PA-RISC, there is no point to | |
204 | enable this option otherwise. The 64bit kernel is significantly bigger | |
205 | and slower than the 32bit one. | |
