These patches add the MEI/Panasonic MN10300/AM33 architecture to the Linux
kernel.
The first patch suppresses A.OUT support in the kernel if CONFIG_BINFMT_AOUT=n
and CONFIG_IA32_AOUT=n and CONFIG_BINFMT_AOUT32=n. MN10300 does not support
the AOUT binfmt, so the ELF binfmt should not be permitted to go looking for
AOUT libraries to load, nor should random bits of the kernel depend on
asm/a.out.h.
The fifth patch adds the architecture itself, to be selected by ARCH=mn10300 on
the make command line.
The patches can also be downloaded from:
http://people.redhat.com/~dhowells/mn10300/mn10300-arch.tar.bz2
A suitable toolchain can be downloaded from:
ftp://ftp.redhat.com/pub/redhat/gnupro/AM33/
The latest is currently:
am33-04r2-5/tools/i686-pc-linux-gnulibc2.3-x-am33_2.0-linux-gnu.tar.bz2
Changes:
(*) Fixed various Makefile stuff.
(*) Fixed up copyright banners.

Suppress A.OUT library support if CONFIG_BINFMT_AOUT is not set.
Not all architectures support the A.OUT binfmt, so the ELF binfmt should not
be permitted to go looking for A.OUT libraries to load in such a case. Not
only that, but under such conditions A.OUT core dumps are not produced either.
To make this work, this patch also does the following:
(1) Makes the existence of the contents of linux/a.out.h more or less
contingent on one of:
CONFIG_BINFMT_AOUT=[ym]
CONFIG_IA32_AOUT=[ym]
CONFIG_BINFMT_AOUT32=[ym]
(2) Moves STACK_TOP[_MAX] out of asm/a.out.h and into asm/processor.h as
they're required whether or not A.OUT format is available.
(3) Renames dump_thread() to aout_dump_thread() as it's only called by A.OUT
core dumping code.
(4) Moves aout_dump_thread() into asm/a.out-core.h and makes it inline. This
is then included only where needed. This means that this bit of arch
code will be stored in the appropriate A.OUT binfmt module rather than
the core kernel.
(5) Removes a lot of now obsolete {linux,asm}/a.out.h inclusions.
(6) Drops A.OUT support for Blackfin (according to Mike Frysinger it's not
needed).

Note that because of unexport-asm-pageh.patch I turned the above hunk into

I do not like this patch for the following reasons:
- too many cleanups lumped into one patch
- it adds #ifdef's in fs/binfmt_elf.c for code that is anyway
scheduled for removal in 2.6.25

Perhaps, but unfortunately a lot of them are related and required for a
compilable patch. I can probably split it up 4 ways if you really want me
to, in order:
(1) Move STACK_TOP[_MAX].
(2) Rename dump_thread() -> aout_dump_thread().
(3) Everything else.
(4) Remove obsolete a.out.h inclusions.
I don't think it's really worth splitting (2) from (3) though.

Yes, but that patch isn't there now, and won't be there in the next version -
assuming this arch has a hope of getting in on that one - according to your
statement.

It's BTW not an improvement that you do not only rename them but change
such big functions to static inline functions in header files.

I'm not the one to decide, but the only excuse for getting that late
into 2.6.24 would be "it can't cause any regression".
The arch/mn10300/ and include/asm-mn10300/ additions can't cause
regressions, and for all the drivers/ parts it seems to be easily
verifiable that they can't cause regressions.
But changes to binfmt_elf.c after the merge window that might introduce
regressions (e.g. you (ab)use CONFIG_BINFMT_AOUT where you might have to
introduce an CONFIG_ARCH_SUPPORTS_AOUT instead) decrease your chances of
being merged that late.
But you might be able to do something like a
cp include/asm-xtensa/a.out.h include/asm-mn10300/
instead.

I'm not sure what you meant by that.
Renaming them indicates more clearly that their only purpose is for A.OUT
support.
Making them inline is an improvement because it compiles the code into the
binfmt_aout module rather than the core kernel, and gives the compiler
optimiser a chance to reduce the size of the overall code.
And the functions aren't actually all that big or complex. They're about
shovelling data and don't do anything clever.
Actually, I could probably do another patch split to inline these functions
first before doing AOUT suppression.

That was more or less what I wanted to do originally, but I was told to use
CONFIG_BINFMT_AOUT instead - which actually proves to have two variants:-(
Perhaps I could start with the patch that you mentioned to remove AOUT
interpreter support from binfmt_elf. Can you point me at it or send it to me?
That's still not sufficient, but it removes part of the changes I have to
make.

No. That would be wrong. MN10300 does not define an exec struct, and nor
should it provide an asm/a.out.h header. It does not do AOUT format.

My thoughts go more into the direction that we have hundreds of similar
cases where e.g. a VFS function might currently only by used by OCFS2
and therefore be dead code for most users, and the only maintainable
solution will be to solve these at the compiler and/or linker level.

Read the comment at the top of the xtensa header. ;-)
For 2.6.25 a better solution is appreciated, but for 2.6.24 such a small
dirty workaround that can't cause breakages on other architectures would
be better.

-ffunction-sections can mostly do it, but only for non modular kernels
One problem is that EXPORT_SYMBOL always creates a reference to the function
even when nothing uses it.
We would need a weak EXPORT_SYMBOL and some way to check references
over main kernel and modules. I suppose it could be done as part of modpost
and then generating a custom linker script that only includes the function
sections referenced by anybody. But to make this work it would require
putting all the EXPORT_SYMBOLs into own sections too, but I suppose
that would be possible.
In the past we had trouble that the explicit linker scripts mentioning every
function section made the linker very slow, but perhaps that's fixed now.
The whole thing would likely made a lot of out of tree modules unhappy
though. Distribution kernels might need to turn it off generally because of
that.
The question is if it would be still have a large enough user base without the
distribution kernels. If it would be only used by a few users I don't think
the maintenance overhead would be worth it.

I don't have a patch yet, but I can submit one for -mm* if it's helpful.
It's not very difficult.

I don't remember the technical details, but Denys Vlasenko posted some
patches that implemented -ffunction-sections while retaining exports.
Another approach would be calling gcc with "-combine -fwhole-program".
David Woodhouse once sent a whacky patch that implemented this on a
per-module basis retaining exports.
Much harder, but with the biggest possible savings, would be a
CONFIG_MODULES=n kernel built with one gcc call.

You forget the big embedded userbase - some even stay at kernel 2.4
since kernel 2.6 is much bigger.

Exactly. This function is for use in something that can be compiled as a
module, therefore this sort of thing is academic - unless we take away the
ability of the aout binfmt to be built as a module.
What's wrong, anyway, with inlining the function?

Ah... That tells emacs that it's a makefile. In Kbuild.asm emacs thinks its
an Assembly file and not a makefile. This causes it to attempt to do
automatic indentation on it. Do you want me to drop these annotation

Doesn't worry me, but I'd suggest that such annotation be added to all such
files in a single separate patch.
otoh it'd be pretty dumb of emacs if there wasn't some way of telling it
the type of a file external from that file itself.

I forget which Kbuild file that was. But with the above change, both
include/asm-generic/Kbuild.asm and include/linux/Kbuild are using
unifdef-y.

Of course. It works for any filename beginning with the string "Kbuild". Major
mode rules are on a first match basis, so you have to make sure this rule is
ahead of the .asm rule. I'll push a patch to the XEmacs guys so it works this
way by default, someone else can deal with Stallman.

Well it's just one line - hardly a big deal.
However if that line was a good one then we should get organised and
annotate all Kbuild files in the tree and appoint you
kbuild-makefile-tag-maintainer.
And if it wasn't a good line then it shouldn't have been added.

IFF we're going to annotate files like this, then also add the magic
incantation to make vim do the right thing :-)

How about we change its name to something more sensible instead? We
only need this hack because the file has a .asm extension. It is
entirely reasonable for an editor (or a person!) to conclude that a
file with a .asm extension contains assembly language.

Bah, an entirely too sensical suggestion :-)

I'm told (by Ralf) that removing this support will break Castle Wolfenstein or
something like that.
So unless you want hordes of rampaging MIPS users breaking down your door
whilst waving pitchforks and torches, maybe this needs to be reconsidered...

The wonders of asynchronous IRC communication ...
Wolfenstein is a true a.out binary and for a long time it was _the_ a.out
binary. If it was working no user would complain ;-)

Then it's unrelated to this issue.
At the time when I was playing Wolfenstein I was using M$ DOS, but I'd
assume the "rampaging MIPS users" was another misunderstanding and
it's i386?
