Mark arches that support A.OUT format by including the following in their master Kconfig files: config ARCH_SUPPORTS_AOUT def_bool y This should also be set if the arch provides compatibility A.OUT support for an older arch, for instance x86_64 for i386 or sparc64 for sparc. I've guessed at which arches don't, based on comments in the code, however I'm sure that some of the ones I've marked as 'yes' actually should be 'no'.

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
|

which is required on some machines.

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
|

selected (the vast majority of 32bit binaries work perfectly fine
|
|
with a larger page size).

4KB For best 32bit compatibility
|

16KB For best performance

64KB For best performance, might give more overhead.

If you don't know what to do, choose 4KB.

---help---
|

This enables support for systems with more than one CPU. If you have
|
|
a system with only one CPU, like most personal computers, say N. If
|
|
you have a system with more than one CPU, say Y.
|
|
|
|
If you say N here, the kernel will run on single 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,
|
|
singleprocessor machines. On a singleprocessor machine, the kernel
|
|
will run faster if you say N here.
