[GIT PULL] Please pull RDMA subsystem changes

[Jason Gunthorpe]

Hi Linus,

This fixes one major regression with NFS and mlx4 due to the max_sg
rework in this merge window, tidies a few minor error_path
regressions, and various small fixes.

The HFI1 driver is broken this cycle due to a regression caused by a
PCI change, it is looking like Bjorn will merge a fix for this. Also,
the lingering ipoib issue I mentioned earlier still remains unfixed.

The following changes since commit 57361846b52bc686112da6ca5368d11210796804:
