kbuild fixes for -rc1 (touches all arch .lds files)

kbuild fixes for -rc1 (touches all arch .lds files)

[Sam Ravnborg]

I have following set of fixes queued for -rc1.
I no major comments are raised I will request for
inclusion tomorrow.


This patchset include the discussed infrastructure to silence
section mismatch warnings in the legitimite cases.
Included are also a few section mismatch fixes so my x86_64
and i386 defconfig builds are with no section mismatchs warnings.
modpost saw various improvements too.

Mike Frysinger have improved gen_initramfs.list and made the
source in scripts/ a tad more portable.

The most important bugfix is the MODALIAS fix for powerpc.


Patches will follow.

	Sam

Subject: [PATCH 01/14] kbuild: make modpost section warnings clearer

Change modpost section mismatch warnings to be less confusing;
model them on the binutils linker warnings which we all know how
to interpret.

Also, fix the wrong ordering of arguments for the final case -
fromsec and refsymname were reversed.

[PATCH 02/14] kbuild: make better section mismatch reports on i386, arm and mips

[Sam Ravnborg]

From 41fa40aeb2314458b25dd2227dc71fdecb504e5e Mon Sep 17 00:00:00 2001
From: Atsushi Nemoto <anemo@mba.ocn.ne.jp>
Date: Thu, 17 May 2007 01:14:38 +0900
Subject: [PATCH 02/14] kbuild: make better section mismatch reports on i386, arm and mips

On i386, ARM and MIPS, warn_sec_mismatch() sometimes fails to show
usefull symbol name.  This is because empty 'refsym' due to 0 r_addend
value.  This patch is to adjust r_addend value, consulting with
apply_relocate() routine in kernel code.

Without this patch:
  MODPOST vmlinux
WARNING: init/built-in.o - Section mismatch: reference to .init.text: from .text between 'rest_init' (at offset 0xf4) and 'try_name'
WARNING: mm/built-in.o - Section mismatch: reference to .init.text: from .text between 'kmem_cache_create' (at offset 0x18a39) and 'cache_reap'
WARNING: mm/built-in.o - Section mismatch: reference to .init.text: from .text between 'kmem_cache_create' (at offset 0x18a6b) and 'cache_reap'

With this patch:
  MODPOST vmlinux
WARNING: mm/built-in.o - Section mismatch: reference to .init.text:set_up_list3s from .text between 'kmem_cache_create' (at offset 0x18a39) and 'cache_reap'
WARNING: mm/built-in.o - Section mismatch: reference to .init.text:set_up_list3s from .text between 'kmem_cache_create' (at offset 0x18a6b) and 'cache_reap'

Now modpost can detect "kernel_init" name (and whitelist it) and show
"set_up_list3s" name.

[PATCH 06/14] kbuild: introduce __init_refok/__initdata_refok to supress section mismatch warnings

[Sam Ravnborg]

Subject: [PATCH 06/14] kbuild: introduce __init_refok/__initdata_refok to supress section mismatch warnings

Throughout the kernel there are a few legitimite references
to init or exit sections. Most of these are covered by the
patterns included in modpost but a few nees special attention.
To avoid hardcoding a lot of function names in modpost introduce
a marker so relevant function/data can be marked.
When modpost see a reference to a init/exit function from
a function/data marked no warning will be issued.

Idea from: Andrew Morton <akpm@linux-foundation.org>

[PATCH 08/14] mm: fix section mismatch warnings

[Sam Ravnborg]

From 90deffab03386508abfa1529fe4926a2fc7300f2 Mon Sep 17 00:00:00 2001
From: Sam Ravnborg <sam@ravnborg.org>
Date: Thu, 17 May 2007 23:29:25 +0200
Subject: [PATCH 08/14] mm: fix section mismatch warnings

modpost had two cases hardcoded for mm/
Shift over to __init_refok and kill the
hardcoded function names in modpost.

This has the drawback that the functions
will always be kept no matter configuration.
With previous code the function were placed in
init section if configuration allowed it.

[PATCH 10/14] powerpc: Fix the MODALIAS generation in modpost for of devices

Subject: [PATCH 10/14] powerpc: Fix the MODALIAS generation in modpost for of devices

Since the devices may have multiple (or none) compatible properties,
the uevent generated internally by the kernel may have multiple
"C..." entries. So the MODALIAS stored in the module must have
wilcard before and after the compatible entry.
Also, if the 'compatible' field is not used for matching, there
will be no 'C' and that must handled as well.

The previous code handled all those case incorrectly and it
"mostly" worked ... but not always.

Subject: [PATCH 12/14] kbuild: add support for squashing uid/gid in gen_initramfs_list.sh

Sometimes it is useful to squash all uid's/gid's to 0:0 regardless of
current owner.  For example, in build systems that get run as arbitrary
users (uClinux-dist).  This adds a special "squash" keyword so you can do
'-g squash -u squash' and have ownership squashed to root.

Change modpost section mismatch warnings to be less confusing;
model them on the binutils linker warnings which we all know how
to interpret.

Also, fix the wrong ordering of arguments for the final case -
fromsec and refsymname were reversed.

Thanks for doing these kinds of consolidations Sam, most of
us arch maintainers really appreciate it.

Looking at these patches reminds me of a quirk in the generic
RODATA definition:

>  #define RODATA								\
>  	. = ALIGN(4096);						\
>  	.rodata           : AT(ADDR(.rodata) - LOAD_OFFSET) {		\

It uses ALIGN(4096) which is likely supposed to be something
like ALIGN(PAGE_SIZE).  Perhaps we should handle this by
definiting a LD_PAGE_SIZE at the top of vmlinux.ld.S files
that need a value other than 4096, and define the default of
4096 in asm-generic/vmlinux.lds.h?

If you could take care of this I'd really appreciate it.

Thnaks, fixed locally.

I would much rather use PAGE_SIZE direct since we have access to that symbol.
I would require a small modification in most asm-*/page.h files
so ld can parse them:

#define PAGE_SIZE (1UL << PAGE_SHIFT)
will become
#define PAGE_SIZE (_AC(1,UL) << PAGE_SHIFT)

This will allow the arch's to use that symbol in assembler too
which is a win.

Then we could do something like:

#define RODATA(alignment)	\
	ALIGN(alignment)	\

And on the call site we will most likely use

	RODATA(PAGE_SIZE)

But the architecture can override it.
Full flexibility and acceptable documentation.

Will do.
And may expend the effort a bit further when attacking the .lds files.

It will be a week or two before I get at it.

I completely agree, that seems to be what platforms which have
a configurable page size such as powerpc, ia64, etc. are already
using in their vmlinux.lds.S files, and I'll likely follow suit on
sparc64. :-)

Thanks a lot.

If you hold of a bit I would like to use sparc64 as template for
a bit more consolidation.
Most likely I will try to consolidate vmlinux.lds for sparc64 and ARM
at the same time and then take the other arch's one by one.

In the process the vmlinux.lds will start to use a consistent
indenting like the following.

Sample diff only on top of -linus.
I will redo it when I have my current patch-set applied.
