linux-next: manual merge of the rdma tree with the rdma-fixes tree

[Stephen Rothwell]

Hi all,

Today's linux-next merge of the rdma tree got a conflict in:

  drivers/infiniband/sw/rxe/rxe.c

between commit:

  8ce2eb9dfac8 ("RDMA/rxe: Fix the failure of ibv_query_device() and ibv_query_device_ex() tests")

from the rdma-fixes tree and commit:

  d34d0bdb500e ("RDMA/rxe: Replace netdev dev addr with raw_gid")

from the rdma tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.
