 174           If you configure the kernel to include many drivers built-in instead
 175           as modules, the kernel executable may become too big, so that the
 176           linker will not be able to resolve some long branches and fails to link
 177           your vmlinux kernel. In that case enabling this option will help you
 178           to overcome this limit by using the -mlong-calls compiler option.
 179
 180           Usually you want to say N here, unless you e.g. want to build
 181           a kernel which includes all necessary drivers built-in and which can
 182           be used for TFTP booting without the need to have an initrd ramdisk.

 193           or having a 64bit-only capable PA-RISC machine should say Y here.
 194
 195           Since there is no 64bit userland on PA-RISC, there is no point to
 196           enable this option otherwise. The 64bit kernel is significantly bigger

 233           than one CPU, say Y.

 239           will run faster if you say N here.
