170    help
171      If you configure the kernel to include many drivers built-in instead
172      as modules, the kernel executable may become too big, so that the
173      linker will not be able to resolve some long branches and fails to link
174      your vmlinux kernel. In that case enabling this option will help you
175      to overcome this limit by using the -mlong-calls compiler option.
176
177      Usually you want to say N here, unless you e.g. want to build
178      a kernel which includes all necessary drivers built-in and which can
179      be used for TFTP booting without the need to have an initrd ramdisk.
180
181      Enabling this option will probably slow down your kernel.

187      Enable this if you want to support 64bit kernel on PA-RISC platform.
188
189      At the moment, only people willing to use more than 2GB of RAM,
190      or having a 64bit-only capable PA-RISC machine should say Y here.
191
192      Since there is no 64bit userland on PA-RISC, there is no point to
193      enable this option otherwise. The 64bit kernel is significantly bigger
194      and slower than the 32bit one.

203      This lets you select the page size of the kernel. For best
204      performance, a page size of 16KB is recommended. For best
205      compatibility with 32bit applications, a page size of 4KB should be
206      selected (the vast majority of 32bit binaries work perfectly fine
207      with a larger page size).
208
209      4KB For best 32bit compatibility
210      16KB For best performance

229      This enables support for systems with more than one CPU. If you have
230      a system with only one CPU, like most personal computers, say N. If
231      you have a system with more than one CPU, say Y.
232
233      If you say N here, the kernel will run on single and multiprocessor
234      machines, but will use only one CPU of a multiprocessor machine. If
235      you say Y here, the kernel will run on many, but not all,
236      singleprocessor machines. On a singleprocessor machine, the kernel
237      will run faster if you say N here.
