Subject: [GIT PATCH] Second round of kbuild updates

Hi Linus.

Please pull the following changes from kbuild.git:

ssh://master.kernel.org/pub/scm/linux/kernel/git/sam/kbuild.git

The diffstat say that a relative high number of files are touched.
This is due to the set of patches from Mathieu that introduce
an arch common Kconfig file and start utilizing it.
The rest are much simpler.

The most visible change is that I have made all the section mismatch
warning prints go away and in the end of the build modpost simply
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 section mismatch logic were changed so we no longer complain
about exported symbols annotated __devinit, __cpuinit, __meminit
as they all seemed to be dealt with properly and the hack needed
to avoid the warnings was not worth the effort.

And I killed the irritating "select of unknown symbol warning".

The scsi change is acked by James and he said OK to get it in via kbuild.git.

Patches has been sent out for review one day ago and comments has been
addressed.
As Andrew has picked up the updated kbuild.git tree I think it is
easiest to get this in before Andrew starts merging his pile of patches.

AVR32 still includes Kconfig.instrumentation, so it won't build after
this...

I did point this out when the patch was submitted, I sent the avr32
pull request early as promised (more than a week ago), but it still
broke. Please apply the fix below. This fixes 2.6.24-mm1 too.

This one slipped through.

Sorry for not catching this.
I just blow away my git tree at kernel.org to avoid getting it
merged with the bug but Linus was too quick for me so he already
merged kbuild.git and applied this patch afterwards.

Ok, the result looks good. Thanks.

Bisecting on avr32 will be a nightmare though, but not only because of
this patch...

This problem had not required a cross-tool chain - so no excuses but..
I recal I once had an AVR32 toolchain but I lost it when I got my new dev box.

Any pointer to a recent AVR32 toolchain I can use for test builds.
