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

  83. which is required on some machines.

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

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

  153. ---help---
  154. This enables support for systems with more than one CPU. If you have
  155. a system with only one CPU, like most personal computers, say N. If
  156. you have a system with more than one CPU, say Y.
  157. If you say N here, the kernel will run on single and multiprocessor
  158. machines, but will use only one CPU of a multiprocessor machine. If
  159. you say Y here, the kernel will run on many, but not all,
  160. singleprocessor machines. On a singleprocessor machine, the kernel
  161. will run faster if you say N here.
  162. See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO
  163. available at <http://www.tldp.org/docs.html#howto>.
