  133. If you configure the kernel to include many drivers built-in instead
  134. as modules, the kernel executable may become too big, so that the
  135. linker will not be able to resolve some long branches and fails to link
  136. your vmlinux kernel. In that case enabling this option will help you
  137. to overcome this limit by using the -mlong-calls compiler option.
  138. Usually you want to say N here, unless you e.g. want to build
  139. a kernel which includes all necessary drivers built-in and which can
  140. be used for TFTP booting without the need to have an initrd ramdisk.
  141. Enabling this option will probably slow down your kernel.

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

  158. This lets you select the page size of the kernel. For best
  159. performance, a page size of 16KB is recommended. For best
  160. compatibility with 32bit applications, a page size of 4KB should be
  161. selected (the vast majority of 32bit binaries work perfectly fine
  162. with a larger page size).
  163. 4KB For best 32bit compatibility
  164. 16KB For best performance
  165. 64KB For best performance, might give more overhead.

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