186 | depends on PA8X00 | |
187 | help | |
188 | If you configure the kernel to include many drivers built-in instead | |
189 | as modules, the kernel executable may become too big, so that the | |
190 | linker will not be able to resolve some long branches and fails to link | |
191 | your vmlinux kernel. In that case enabling this option will help you | |
192 | to overcome this limit by using the -mlong-calls compiler option. | |
193 | ||
194 | Usually you want to say N here, unless you e.g. want to build | |
195 | a kernel which includes all necessary drivers built-in and which can | |
196 | be used for TFTP booting without the need to have an initrd ramdisk. | |
197 | ||
198 | Enabling this option will probably slow down your kernel. | |

208 | ||
209 | Since there is no 64bit userland on PA-RISC, there is no point to | |
210 | enable this option otherwise. The 64bit kernel is significantly bigger | |
211 | and slower than the 32bit one. | |
