I have no doubt that it is a 2.6.32 kernel. The question is to know
whether it is a vanilla kernel, i.e. coming from kernel.org. Since in
your first post the kernel directory was named linux_0030 or something
like that, I assumed it was not. But in any case it does not change
anything since the I-pipe patch for arm does not exist for linux-2.6.32
either.

It will work better if the branch "vendor" comes from the vendor git.

Ill-chosen name. Since this is the branch where you will make the merge,
you should call it, say, vendor+ipipe-2.6.32-arm. Having a branch called
ipipe-2.6.32-noarch which in fact contains the vendor kernel patches with

That was expected.

You do not really need to checkout this branches. All you need is to
generate the patch with:
git diff origin/ipipe-2.6.31-noarch origin/ipipe-2.6.31-arm

The rejects are expected, you are applying changes for a 2.6.31 kernel
to a 2.6.32 kernel, vendor-specific or not, this makes rejects. Anyway,
maybe you will get less rejects if you use 2.6.33 instead of 2.6.31.

Rejects in entry-*.S are no good sign, and will be hard to fix (without
more knowledge of the Adeos patch). Please try 2.6.33.
