Hi Paulus,
I think the following 3 patches are no longer contentious - I have removed
some of the files from the third that people expressed concersn over.
Please send at least the first upstream. The other two can also probably
be sent.

The ppc and ppc64 trees are hopefully going to merge over time, so this
patch begins the process by creating a place for the merging of the
header files.
Create include/asm-powerpc (and move linkage.h into it from
asm-{ppc,ppc64} since we don't like empty directories). Modify the
ppc and ppc64 Makefiles to cope.

Move the identical files from include/asm-ppc{,64}/ to
include/asm-powerpc/. Remove hdreg.h completely as it is unused in
the tree.

These certainly look good to me.
This is another patch to merge the atomic.h file. It is not completely
trivial and changes the semantics for 32 bit SMP systems, which previously
did not do EIEIO_ON_SMP within the atomic operations. AFAICT, that was
a bug in the 32 bit version, which is now fixed as a side-effect of
the merge.
The combined version of this file also prevents building user space
applications using atomic.h on ppc64. That was already impossible
on 32 bit ppc, but probably also created broken output on ppc64.

Paul,
I'd like to call attention to this buried patch. It appears that
it might be lost due to Subject: line swiping; it likely hasn't
gotten first class status as its own independent patch.
Any chance we can get this one reviewed and pushed upstream too?
Thanks,
jdl

I went to send it on yesterday and found that it doesn't apply any
more. If Arnd or someone would like to update it, I'll send it on.
Paul.

Hmm. I don't get rejects against the git head. For which tree do
you want the patch?
