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

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

 201           This lets you select the page size of the kernel.  For best
 202           performance, a page size of 16KB is recommended.  For best
 203           compatibility with 32bit applications, a page size of 4KB should be

 227           This enables support for systems with more than one CPU. If you have

 230
 231           If you say N here, the kernel will run on single and multiprocessor
 232           machines, but will use only one CPU of a multiprocessor machine. If
 233           you say Y here, the kernel will run on many, but not all,
 234           singleprocessor machines. On a singleprocessor machine, the kernel
 235           will run faster if you say N here.
