Merge branch 'mlx5_memic_ops' of git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux

Maor Gottlieb says:
====================
This series from Maor extends MEMIC to support atomic operations from the
host in addition to already supported regular read/write.
====================

* 'memic_ops':
  RDMA/mlx5: Expose UAPI to query DM
  RDMA/mlx5: Add support in MEMIC operations
  RDMA/mlx5: Add support to MODIFY_MEMIC command
  RDMA/mlx5: Re-organize the DM code
  RDMA/mlx5: Move all DM logic to separate file
  RDMA/uverbs: Make UVERBS_OBJECT_METHODS to consider line number
  net/mlx5: Add MEMIC operations related bits
