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

 191           At the moment, only people willing to use more than 2GB of RAM,
 192           or having a 64bit-only capable PA-RISC machine should say Y here.
 193
 194           Since there is no 64bit userland on PA-RISC, there is no point to
 195           enable this option otherwise. The 64bit kernel is significantly bigger

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

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