Ah, I see them now. I should make sure I look more closely next time.
That definitely explains why I couldn't get this to merge into my
for-next branch cleanly.

Ok. Conflicts are not the problem though, I can handle them and sfr can
handle them for linux-next, too. Real dependencies are the problem,
where you rely on a feature that is part of another tree.

Yes and no. You simply cannot ask me to merge a branch that is based on
top of Russell's for-next branch, since that is getting rebased. It is
also bad if the stuff doesn't have any linux-next exposure, so we should
try to find another way out.

I've now rebased your tree on top of 3.1-rc9 plus the stable branches
from Russell's tree that I already have as dependencies in arm-soc/for-next
(devel-stable, smp, debug). This has caused no conflicts for me, but
that doesn't mean that it's correct. Please check that what I have
in arm-soc/dt/gic and arm-soc/highbank/soc actually works for you
and does not contain branches that you don't actually need.
