  93. used for optimizing purposes. In order to compile a kernel
  94. that can run on all 32-bit PA CPUs (albeit not optimally fast),
  95. you can specify "PA7000" here.

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

  149. This lets you select the page size of the kernel. For best
  150. performance, a page size of 16KB is recommended. For best
  151. compatibility with 32bit applications, a page size of 4KB should be
  152. selected (the vast majority of 32bit binaries work perfectly fine
  153. with a larger page size).
  154. 4KB For best 32bit compatibility
  155. 16KB For best performance
  156. 64KB For best performance, might give more overhead.
  157. If you don't know what to do, choose 4KB.

  169. This enables support for systems with more than one CPU. If you have
  170. a system with only one CPU, like most personal computers, say N. If
  171. you have a system with more than one CPU, say Y.
  172. If you say N here, the kernel will run on single and multiprocessor
  173. machines, but will use only one CPU of a multiprocessor machine. If
  174. you say Y here, the kernel will run on many, but not all,
  175. singleprocessor machines. On a singleprocessor machine, the kernel
  176. will run faster if you say N here.
