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

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

 202           This lets you select the page size of the kernel.  For best

 204           compatibility with 32bit applications, a page size of 4KB should be
 205           selected (the vast majority of 32bit binaries work perfectly fine

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

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