Hi Linus,

Here are the changes for RDMA for this cycle, there was a small rxe
conflict with v6.4 that I resolved in the usual way.

Thanks,
Jason

Merge tag 'v6.4' into rdma.git for-next (2023-06-27 14:06:29 -0300)

----------------------------------------------------------------
v6.5 merge window RDMA pull request

This cycle saw a focus on rxe and bnxt_re drivers:

- Code cleanups for irdma, rxe, rtrs, hns, vmw_pvrdma

- rxe uses workqueues instead of tasklets

- rxe has better compliance around access checks for MRs and rereg_mr

- mana supportst he 'v2' FW interface for RX coalescing

- hfi1 bug fix for stale cache entries in its MR cache

- mlx5 buf fix to handle FW failures when destroying QPs

- erdma HW has a new doorbell allocation mechanism for uverbs that is
secure

- Lots of small cleanups and rework in bnxt_re
* Use the common mmap functions
* Support disassociation
* Improve FW command flow

- bnxt_re support for "low latency push", this allows a packet
