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

 195           or having a 64bit-only capable PA-RISC machine should say Y here.
 196
 197           Since there is no 64bit userland on PA-RISC, there is no point to
 198           enable this option otherwise. The 64bit kernel is significantly bigger
 199           and slower than the 32bit one.

 233           This enables support for systems with more than one CPU. If you have

 235           than one CPU, say Y.
 236
 237           If you say N here, the kernel will run on uni- and multiprocessor
 238           machines, but will use only one CPU of a multiprocessor machine. If
 239           you say Y here, the kernel will run on many, but not all,
 240           uniprocessor machines. On a uniprocessor machine, the kernel
 241           will run faster if you say N here.
