92 that can run on all 32-bit PA CPUs (albeit not optimally fast),
93 you can specify "PA7000" here.

143 help
144 Enable this if you want to support 64bit kernel on PA-RISC platform.
145
146 At the moment, only people willing to use more than 2GB of RAM,
147 or having a 64bit-only capable PA-RISC machine should say Y here.
148
149 Since there is no 64bit userland on PA-RISC, there is no point to
150 enable this option otherwise. The 64bit kernel is significantly bigger
151 and slower than the 32bit one.

162 This lets you select the page size of the kernel. For best
163 performance, a page size of 16KB is recommended. For best
164 compatibility with 32bit applications, a page size of 4KB should be
165 selected (the vast majority of 32bit binaries work perfectly fine
166 with a larger page size).

168 4KB For best 32bit compatibility
169 16KB For best performance
170 64KB For best performance, might give more overhead.

185 bool "Symmetric multi-processing support"
186 ---help---
187 This enables support for systems with more than one CPU. If you have
188 a system with only one CPU, like most personal computers, say N. If
189 you have a system with more than one CPU, say Y.
190
191 If you say N here, the kernel will run on single and multiprocessor
192 machines, but will use only one CPU of a multiprocessor machine. If
193 you say Y here, the kernel will run on many, but not all,
194 singleprocessor machines. On a singleprocessor machine, the kernel
195 will run faster if you say N here.
