Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
Pull rdma updates from Jason Gunthorpe:
"Aside from the usual things this has an arch update for
__iowrite64_copy() used by the RDMA drivers.
This API was intended to generate large 64 byte MemWr TLPs on PCI.
These days most processors had done this by just repeating writel() in
a loop. S390 and some new ARM64 designs require a special helper to
get this to generate.
- Small improvements and fixes for erdma, efa, hfi1, bnxt_re
- Fix a UAF crash after module unload on leaking restrack entry
- Continue adding full RDMA support in mana with support for EQs,
GID's and CQs
- Improvements to the mkey cache in mlx5
- DSCP traffic class support in hns and several bug fixes
- Cap the maximum number of MADs in the receive queue to avoid OOM
- Another batch of rxe bug fixes from large scale testing
- __iowrite64_copy() optimizations for write combining MMIO memory
- Remove NULL checks before dev_put/hold()
- EFA support for receive with immediate
- Fix a recent memleaking regression in a cma error path"
