[GIT PULL] Please pull RDMA subsystem changes

[Jason Gunthorpe]

Hi Linus,

I don't usually send rc PRs so late but this cycle there are some
urgent user triggerable bugs that should be expedited. As per your
request I've been putting most of the discovered bugs into the merge
window stream, these ones stood out as particularly significant.

Thanks,
Jason
