Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma

Pull rdma updates from Jason Gunthorpe:
"A quiet cycle after the larger 5.8 effort. Substantially cleanup and
driver work with a few smaller features this time.

- Driver updates for hfi1, rxe, mlx5, hns, qedr, usnic, bnxt_re

- Removal of dead or redundant code across the drivers

- RAW resource tracker dumps to include a device specific data blob
for device objects to aide device debugging

- Further advance the IOCTL interface, remove the ability to turn it
off. Add QUERY_CONTEXT, QUERY_MR, and QUERY_PD commands

- Remove stubs related to devices with no pkey table

- A shared CQ scheme to allow multiple ULPs to share the CQ rings of
a device to give higher performance

- Several more static checker, syzkaller and rare crashers fixed"

Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma

Pull rdma updates from Jason Gunthorpe:
"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.

Summary:

- 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"

- The CPU and kworker for each CQ is evident
- The CQ's restracker ID is tagged on each trace event
- CQ poll scheduling latency is measured
- Details about how often single completions occur versus multiple
completions are evident
- The cost of the ULP's completion handler is recorded
