I just did a git-checkout of
git://git.kernel.org/pub/scm/linux/kernel/git/sfr/linux-next.git
 linux-next/master and got commit:
e85df409b2ad8528fa772379393c81406c417bbf

When I
make allmodconfig; make -j 24 compressed, I get no such warnings.  I do
still see a failure from the SFC driver :(

Are you sure something isn't a little dirty in your work area?  Did you
maybe do a make allyesconfig, allnoconfig, allmodconfig sequence?

Thanks,
Robin

Oh, just realized this could be a gcc version issue as well.  Could you
provide that as well?  I had used the SLES installed version (4.1.2).

Hmmm that looks like the commit for next-20080821, but I see build
failures for 0820 and 0821.

Using "git diff next-20080819 next-20080820" shows the only
change in arch/ia64 is an innocuous looking one to arch/ia64/kvm/irq.h
The only plausible looking stuff is the slab.h and slub_def.h changes
because the first error is reported in efi_initialize_iomem_resources()
which does make a kzalloc() call ... and commenting out the kzalloc()
moves the first reported error out of this function to some other one.

I see the same error with the generic_defconfig ... so it
isn't special to allmodconfig.

I'm using gcc version:
 gcc version 3.4.6 20060404 (Red Hat 3.4.6-8)

So this might be a 3.x vs. 4.x issue.

Heck if I can see where these "__ia64_save_stack_nonlocal" symbols
are coming from though.  I thought that there is some cpp
trickery concatenating tokens ... but a "cc -E" of efi.c didn't
give me any clues :-(

Not sure if this is helpful, but google pointed me at:

That said "Fixed in 4.0.0" ... so I grabbed and built a newer
gcc (4.2.4) and lo and behold the next-20080821 tag builds
and boots just fine[*] with it.

Still need to figure out exactly what broke the build with
a 3.x gcc to see if there is an easy workaround. Though 4.0.0
was released over three years ago ... is it time to give up
on the ancient 3.x technology?

I have been doing a bisect using akpm's compiler to see if I can find
the individual commit.  Unfortunately, my laptop isn't the fastest build
machine in the world.

I did objdump the built-in.o and there is no such symbol in that file.
'strings' agrees.

Yes.  I've got a hard time seeing why anyone would use GCC 3.x to build 
current Linux kernels for Itanium (except when using an acient distro as
the base for kernel development).

The resulting binary should be faster, though. ;-)  How about giving
GCC 4.3 a try, by the way?  IIRC, GCC 4.2 has some aliasing issues
that have been addressed.

Ah, but I spend much more time compiling kernels than I do
running them ... so this isn't a good tradeoff for me ;-)

I tried 4.3.1 and got:

configure: error: Building GCC requires GMP 4.1+ and MPFR 2.3.0+.

So I'll have to do some other upgrading and installing on my
ancient build box to make this work :-(

With gcc 4.1.2 it compiles fine.

So efi_initialize_iomem_resources calls kzalloc() which calls an inline
kmalloc() function. Is this with our without CONFIG_KMEMTRACE enabled?
Any idea what this '__ia64_save_stack_nonlocal' thing is?

Eduard, did you have plans to move the hooks out-of-line as suggested by
Christoph? That patch might "cure" this thing here...

This failed with either CONFIG_KMEMTRACE =y or =n.

I probably could not test this until the weekend at the earliest.  If you
would like to test it yourself, just git-checkout the linux-next/master
tree and use Andrew's cross compiler to make allmodconfig and make
compressed.

I moved my build tools over to a newer, faster box.  gcc4.3.1 built
with no problems ... and built some kernels which seem to be
working just fine.
