For dependencies, branch based on 'mellanox/mlx5-next' of git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux.git Pull Dump and fill MKEY from Leon Romanovsky: ==================== MLX5 IB HCA offers the memory key, dump_fill_mkey to increase performance, when used in a send or receive operations. It is used to force local HCA operations to skip the PCI bus access, while keeping track of the processed length in the ibv_sge handling. In this three patch series, we expose various bits in our HW spec file (mlx5_ifc.h), move unneeded for mlx5_core FW command and export such memory key to user space thought our mlx5-abi header file. ==================== Botched auto-merge in mlx5_ib_alloc_ucontext() resolved by hand. * branch 'mlx5-dump-fill-mkey': IB/mlx5: Expose dump and fill memory key net/mlx5: Add hardware definitions for dump_fill_mkey net/mlx5: Limit scope of dump_fill_mkey function net/mlx5: Rate limit errors in command interface Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
