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

Hi Doug,

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

net/sunrpc/xprtrdma/frwr_ops.c

between commit:

55fdfce101a0 ("xprtrdma: Rename rpcrdma_frwr::sg and sg_nents")

from the nfs tree and commits:

ff2ba9936591 ("IB/core: Add passing an offset into the SG to ib_map_mr_sg")
9aa8b3217ed3 ("IB/core: Enhance ib_map_mr_sg()")

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.
