 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

 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

 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

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

 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.
