13 and later HP3000 series). The PA-RISC Linux project home page is

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

136 Enable this if you want to support 64bit kernel on PA-RISC platform.
137
138 At the moment, only people willing to use more than 2GB of RAM,
139 or having a 64bit-only capable PA-RISC machine should say Y here.
140
141 Since there is no 64bit userland on PA-RISC, there is no point to
142 enable this option otherwise. The 64bit kernel is significantly bigger
143 and slower than the 32bit one.

154 This lets you select the page size of the kernel. For best
155 performance, a page size of 16KB is recommended. For best
156 compatibility with 32bit applications, a page size of 4KB should be
157 selected (the vast majority of 32bit binaries work perfectly fine
158 with a larger page size).
159
160 4KB For best 32bit compatibility
161 16KB For best performance
162 64KB For best performance, might give more overhead.

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