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

  126. Enable this if you want to support 64bit kernel on PA-RISC platform.
  127. At the moment, only people willing to use more than 2GB of RAM,
  128. or having a 64bit-only capable PA-RISC machine should say Y here.
  129. Since there is no 64bit userland on PA-RISC, there is no point to
  130. enable this option otherwise. The 64bit kernel is significantly bigger
  131. and slower than the 32bit one.

  138. This lets you select the page size of the kernel. For best
  139. performance, a page size of 16KB is recommended. For best
  140. compatibility with 32bit applications, a page size of 4KB should be
  141. selected (the vast majority of 32bit binaries work perfectly fine
  142. with a larger page size).
  143. 4KB For best 32bit compatibility
  144. 16KB For best performance
  145. 64KB For best performance, might give more overhead.

  158. This enables support for systems with more than one CPU. If you have
  159. a system with only one CPU, like most personal computers, say N. If
  160. you have a system with more than one CPU, say Y.
  161. If you say N here, the kernel will run on single and multiprocessor
  162. machines, but will use only one CPU of a multiprocessor machine. If
  163. you say Y here, the kernel will run on many, but not all,
  164. singleprocessor machines. On a singleprocessor machine, the kernel
  165. will run faster if you say N here.
