174 Enable this if you want to support 64bit kernel on PA-RISC platform.
175
176 At the moment, only people willing to use more than 2GB of RAM,
177 or having a 64bit-only capable PA-RISC machine should say Y here.
178
179 Since there is no 64bit userland on PA-RISC, there is no point to
180 enable this option otherwise. The 64bit kernel is significantly bigger
181 and slower than the 32bit one.

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

218 This enables support for systems with more than one CPU. If you have
219 a system with only one CPU, like most personal computers, say N. If
220 you have a system with more than one CPU, say Y.
221
222 If you say N here, the kernel will run on single and multiprocessor
223 machines, but will use only one CPU of a multiprocessor machine. If
224 you say Y here, the kernel will run on many, but not all,
225 singleprocessor machines. On a singleprocessor machine, the kernel
226 will run faster if you say N here.
