[GIT PULL] Please pull RDMA subsystem changes

From: Jason Gunthorpe
Date: Fri Jan 31 2020 - 10:16:35 EST

Hi Linus,

These are the proposed RDMA patches for 5.6.

A very quiet cycle with few notable changes. Mostly the usual list of one or
two patches to drivers changing something that isn't quite rc worthy. The
subsystem seems to be seeing a larger number of rework and cleanup style
patches right now, I feel that several vendors are prepping their drivers for
new silicon.

Thanks,
Jason

RDMA/core: Make the entire API tree static (2020-01-30 16:28:52 -0400)

----------------------------------------------------------------
RDMA subsystem updates for 5.6

- Driver updates and cleanup for qedr, bnxt_re, hns, siw, mlx5, mlx4, rxe,
i40iw

- Larger series doing cleanup and rework for hns and hfi1.

- Some general reworking of the CM code to make it a little more
understandable

- Unify the different code paths connected to the uverbs FD scheme

- New UAPI ioctls conversions for get context and get async fd

- Trace points for CQ and CM portions of the RDMA stack

- mlx5 driver support for virtio-net formatted rings as RDMA raw ethernet QPs

- verbs support for setting the PCI-E relaxed ordering bit on DMA traffic
connected to a MR

- A couple of bug fixes that came too late to make rc7
