16 The PA-RISC microprocessor is designed by Hewlett-Packard and used
17 in many of their workstations & servers (HP9000 700 and 800 series,
18 and later HP3000 series). The PA-RISC Linux project home page is

108 This is the processor type of your CPU. This information is
109 used for optimizing purposes. In order to compile a kernel
110 that can run on all 32-bit PA CPUs (albeit not optimally fast),
111 you can specify "PA7000" here.

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
181 performance, a page size of 16KB is recommended. For best
182 compatibility with 32bit applications, a page size of 4KB should be
183 selected (the vast majority of 32bit binaries work perfectly fine
184 with a larger page size).
185
186 4KB For best 32bit compatibility
187 16KB For best performance
188 64KB For best performance, might give more overhead.

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.
