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

188
189	  At the moment, only people willing to use more than 2GB of RAM,
190	  or having a 64bit-only capable PA-RISC machine should say Y here.
191
192	  Since there is no 64bit userland on PA-RISC, there is no point to
193	  enable this option otherwise. The 64bit kernel is significantly bigger
194	  and slower than the 32bit one.

230	  a system with only one CPU, like most personal computers, say N. If
231	  you have a system with more than one CPU, say Y.
232
233	  If you say N here, the kernel will run on single and multiprocessor
234	  machines, but will use only one CPU of a multiprocessor machine. If
235	  you say Y here, the kernel will run on many, but not all,
236	  singleprocessor machines. On a singleprocessor machine, the kernel
237	  will run faster if you say N here.
