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

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

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

 234           you have a system with more than one CPU, say Y.
 235
 236           If you say N here, the kernel will run on single and multiprocessor
 237           machines, but will use only one CPU of a multiprocessor machine. If
 238           you say Y here, the kernel will run on many, but not all,
 239           singleprocessor machines. On a singleprocessor machine, the kernel
 240           will run faster if you say N here.
