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

hmm_pfn_to_page() does not return NULL. ib_umem_odp_map_dma_and_lock()

Calling ibv_advise_mr(3) with flags other than IBV_ADVISE_MR_FLAG_FLUSH
invokes an asynchronous request. It is best-effort, and thus can safely be
deferred to the system-wide workqueue.

The reference counter in rxe_mr is used to ensure that the MRs persist and
that rxe is not terminated until the queued work is done.
