Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
Pull rdma updates from Jason Gunthorpe:
- Various minor code cleanups and fixes for hns, iser, cxgb4, hfi1, rxe, erdma, mana_ib
- Prefetch supprot for rxe ODP
- Remove memory window support from hns as new device FW is no longer support it
- Remove qib, it is very old and obsolete now, Cornelis wishes to restructure the hfi1/qib shared layer
- Fix a race in destroying CQs where we can still end up with work running because the work is cancled before the driver stops triggering it
- Improve interaction with namespaces: * Follow the devlink namespace for newly spawned RDMA devices * Create iopoib net devces in the parent IB device's namespace * Allow CAP_NET_RAW checks to pass in user namespaces
- A new flow control scheme for IB MADs to try and avoid queue overflows in the network
- Fix 2G message sizes in bnxt_re
- Optimize mkey layout for mlx5 DMABUF
- New "DMA Handle" concept to allow controlling PCI TPH and steering tags

RDMA/mlx5: Add DMAH object support
This patch introduces support for allocating and deallocating the DMAH object.
Further details: ---------------- The DMAH API is exposed to upper layers only if the underlying device supports TPH.
It uses the mlx5_core steering tag (ST) APIs to get a steering tag index based on the provided input.
The obtained index is stored in the device-specific mlx5_dmah structure for future use.
Upcoming patches in the series will integrate the allocated DMAH into the memory region (MR) registration process.
