Remove an outdated reference to "most personal computers" having only one CPU, and change the use of "singleprocessor" and "single processor" in CONFIG_SMP's documentation to "uniprocessor" across all arches where that documentation is present.

This is the processor type of your CPU. This information is

used for optimizing purposes. In order to compile a kernel
|
|
that can run on all 32-bit PA CPUs (albeit not optimally fast),
|
|
you can specify "PA7000" here.

Specifying "PA8000" here will allow you to select a 64-bit kernel

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

Enable this if you want to support 64bit kernel on PA-RISC platform.

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

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

performance, a page size of 16KB is recommended. For best

compatibility with 32bit applications, a page size of 4KB should be

with a larger page size).

4KB For best 32bit compatibility

16KB For best performance

64KB For best performance, might give more overhead.

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

a system with only one CPU, say N. If you have a system with more

than one CPU, say Y.
|

If you say N here, the kernel will run on uni- and multiprocessor

machines, but will use only one CPU of a multiprocessor machine. If

you say Y here, the kernel will run on many, but not all,

uniprocessor machines. On a uniprocessor machine, the kernel

will run faster if you say N here.
