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

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

206 This lets you select the page size of the kernel. For best

231 This enables support for systems with more than one CPU. If you have
232 a system with only one CPU, like most personal computers, say N. If
233 you have a system with more than one CPU, say Y.
234
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.
