175	help
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.
185
186	  Enabling this option will probably slow down your kernel.

193
194	  At the moment, only people willing to use more than 2GB of RAM,
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
234	  a system with only one CPU, say N. If you have a system with more
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.
