154 help
155 Enable this if you want to support 64bit kernel on PA-RISC platform.
156
157 At the moment, only people willing to use more than 2GB of RAM,
158 or having a 64bit-only capable PA-RISC machine should say Y here.
159
160 Since there is no 64bit userland on PA-RISC, there is no point to
161 enable this option otherwise. The 64bit kernel is significantly bigger
162 and slower than the 32bit one.

173 This lets you select the page size of the kernel. For best
174 performance, a page size of 16KB is recommended. For best
175 compatibility with 32bit applications, a page size of 4KB should be
176 selected (the vast majority of 32bit binaries work perfectly fine
177 with a larger page size).

179 4KB For best 32bit compatibility
180 16KB For best performance
181 64KB For best performance, might give more overhead.

196 bool "Symmetric multi-processing support"
197 ---help---
198 This enables support for systems with more than one CPU. If you have
199 a system with only one CPU, like most personal computers, say N. If
200 you have a system with more than one CPU, say Y.
201
202 If you say N here, the kernel will run on single and multiprocessor
203 machines, but will use only one CPU of a multiprocessor machine. If
204 you say Y here, the kernel will run on many, but not all,
205 singleprocessor machines. On a singleprocessor machine, the kernel
206 will run faster if you say N here.
