With Linus' tree, today's linux-next build (powerpc allyesconfig) failed
like this:

drivers/infiniband/sw/built-in.o:(.opd+0x1698): multiple definition of `copy_data'
drivers/infiniband/hw/built-in.o:(.opd+0xe5f8): first defined here

This looks very suspicious.  I think you are picking up two copies of
the rxe code.  One from Linus tree and one from probably Leon's tree.

Actually the second copy is from your tree
(git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma.git#for-next),
Leon's trees are empty (relative to Linus' tree).  I guess when you
rebased and squashed things, you forgot to reset your for-next tag, so
I got the old version of your tree as well as the rebased version via
Linus' tree.
