162 Enable this if you want to support 64bit kernel on PA-RISC platform.
163
164 At the moment, only people willing to use more than 2GB of RAM,
165 or having a 64bit-only capable PA-RISC machine should say Y here.
166
167 Since there is no 64bit userland on PA-RISC, there is no point to
168 enable this option otherwise. The 64bit kernel is significantly bigger
169 and slower than the 32bit one.

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

184 with a larger page size).

206 This enables support for systems with more than one CPU. If you have
207 a system with only one CPU, like most personal computers, say N. If
208 you have a system with more than one CPU, say Y.
209
210 If you say N here, the kernel will run on single and multiprocessor
211 machines, but will use only one CPU of a multiprocessor machine. If
212 you say Y here, the kernel will run on many, but not all,
213 singleprocessor machines. On a singleprocessor machine, the kernel
214 will run faster if you say N here.
