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
207	  performance, a page size of 16KB is recommended.  For best
208	  compatibility with 32bit applications, a page size of 4KB should be
209	  selected (the vast majority of 32bit binaries work perfectly fine
210	  with a larger page size).

231	  This enables support for systems with more than one CPU. If you have
232	  a system with only one CPU, say N. If you have a system with more
233	  than one CPU, say Y.
234
235	  If you say N here, the kernel will run on uni- 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	  uniprocessor machines. On a uniprocessor machine, the kernel
239	  will run faster if you say N here.
