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

139 depends on PA8X00
140 help
141 Enable this if you want to support 64bit kernel on PA-RISC platform.
142
143 At the moment, only people willing to use more than 2GB of RAM,
144 or having a 64bit-only capable PA-RISC machine should say Y here.
145
146 Since there is no 64bit userland on PA-RISC, there is no point to
147 enable this option otherwise. The 64bit kernel is significantly bigger
148 and slower than the 32bit one.

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

165 4KB For best 32bit compatibility
166 16KB For best performance
167 64KB For best performance, might give more overhead.

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