Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
Pull rdma updates from Jason Gunthorpe:
"A smaller cycle this time. Notably we see another new driver, 'Soft
iWarp', and the deletion of an ancient unused driver for nes.
- Revise and simplify the signature offload RDMA MR APIs
- More progress on hoisting object allocation boiler plate code out
of the drivers
- Driver bug fixes and revisions for hns, hfi1, efa, cxgb4, qib,
i40iw
- Tree wide cleanups: struct_size, put_user_page, xarray, rst doc
conversion
- Removal of obsolete ib_ucm chardev and nes driver
- netlink based discovery of chardevs and autoloading of the modules
providing them
- Move more of the rdamvt/hfi1 uapi to include/uapi/rdma
- New driver 'siw' for software based iWarp running on top of netdev,
much like rxe's software RoCE.
- mlx5 feature to report events in their raw devx format to userspace
- Expose per-object counters through rdma tool
- Adaptive interrupt moderation for RDMA (DIM), sharing the DIM core
from netdev"
