Hi Linus,

These are the proposed RDMA patches for 5.10.

A usual cycle for RDMA with a typical mix of driver and core subsystem
updates. There was a lot of activity in the last week on fixing up some small
patches that were merged during the rc8 period, so the top couple commits are
new things that haven't been in linux-next, but they are all rc-ish unbreaking
stuff.

There is a compilation break after merging this, the signature of
__sg_alloc_table_from_pages() was changed in this PR. The series that did this
has been reviewed and been in linux-next for a while.

You'll need to apply this fixup to the merge commit (it is in the tag
for-linus-merged for reference):

RDMA/ucma: Fix use after free in destroy id flow (2020-10-16 14:07:08 -0300)

----------------------------------------------------------------
RDMA 5.10 pull request

The typical set of driver updates across the subsystem:

- Driver minor changes and bug fixes for mlx5, efa, rxe, vmw_pvrdma, hns,
usnic, qib, qedr, cxgb4, hns, bnxt_re

- Various rtrs fixes and updates

- Bug fix for mlx4 CM emulation for virtualization scenarios where MRA
wasn't working right

- Use tracepoints instead of pr_debug in the CM code

- Scrub the locking in ucma and cma to close more syzkaller bugs

- Use tasklet_setup in the subsystem

- Revert the idea that 'destroy' operations are not allowed to fail at
the driver level. This proved unworkable from a HW perspective.

- Revise how the umem API works so drivers make fewer mistakes using it

- XRC support for qedr

- Convert uverbs objects RWQ and MW to new the allocation scheme

- Large queue entry sizes for hns

- Use hmm_range_fault() for mlx5 On Demand Paging

- uverbs APIs to inspect the GID table instead of sysfs

- Move some of the RDMA code for building large page SGLs into
lib/scatterlist
