I have queued up 10 patched for kbuild.git.
As a few are new I post them for review here
before pushing to Linus.
The patchset from Mathieu causes the hing number of
lines changed - the rest is smaller stuff.
The most visible change is that I have made all the section mismatch
go away and in the end of the build modpost report the number
of section mismatch warnings and how to see detail.
The typical output is now:
modpost: Found 35 section mismatch(es).
To see full details build your kernel with:
'make CONFIG_DEBUG_SECTION_MISMATCH=y'
And CONFIG_DEBUG_SECTION_MISMATCH cannot be set
from the config anymore so we are not noisy in typical
allyesconfig builds.
When we are down to an acceptable number of warnings modpost
will start to be vocal again. The acceptable number is somewhere
below 20 for an allyseconfig/allmodconfig build.
All patches are pushed out to kbuild.git.
See below for more details and a combined patch.
Individual patches will be sent to kbuild only (and no cc:)
Sam
Bryan Wu (1):
kbuild: add svn revision information to setlocalversion
Geert Uytterhoeven (1):
kbuild: Spelling/grammar fixes for config DEBUG_SECTION_MISMATCH
Mathieu Desnoyers (5):
Fix ARM to play nicely with generic Instrumentation menu
Create arch/Kconfig
Add HAVE_OPROFILE
Add HAVE_KPROBES
Move Kconfig.instrumentation to arch/Kconfig and init/Kconfig
Ralf Baechle (1):
Remove __INIT_REFOK and __INITDATA_REFOK
Sam Ravnborg (3):
kbuild: print only total number of section mismatces found
kconfig: mark config as changed when loading an alternate config
kconfig: ignore select of unknown symbol

This looks broken. Unless I'm very much mistaken the 'if' statement is
always going to be true because the awk statement will always execute
without error. Try: echo "" | awk '{print $NF}' || echo Error
So, the code should probably be changed to:
+if rev=`svn info 2>/dev/null | grep '^Revision' ; then
+ rev=`echo $rev | awk '{print $NF}'`
+ changes=`svn status 2>/dev/null | grep '^[AMD]' | wc -l`
or alternatively:
+if rev=`svn info 2>/dev/null | grep '^Revision' | awk '{print $NF}'` && \
+ [ -n "$rev" ] ; then
+ changes=`svn status 2>/dev/null | grep '^[AMD]' | wc -l`
Cheers,
FJP
P.S. Looks like the mercurial section is missing some indentation.
Bryan this was from you - please comment/fix.

Subject: [PATCH] kbuild: do not warn about __*init/__*exit symbols being exported
We have several legitimate uses where we export symbols
annotated with one of:
__devinit, __cpuinit, __meminit and their exit counterpart.
So let's stop warning about those being exported in favour
of adding all sorts of workaround to silence the warning.

You are right, it will always plus a '-svn' string at the end of kernel
version string even if it is not a svn repo.

I prefer to this one. A updated version will be sent out soon.

Can we get a `warning' string literal in that message, so I notice it when
grepping for compiler warnings?
... Ah, there already exists a warn() routine, so let's use it.
Subject: modpost: Use warn() for announcing section mismatches
From: Geert Uytterhoeven <[email protected]>
modpost: Use warn() for announcing section mismatches, for easy grepping for
warnings in build logs.
Also change an existing call from fprintf() to warn() while we're at it.
