Hi,

These are a set of patches [v3] which removes semaphores from infiniband.
These are part of a bigger effort to eliminate all semaphores from the
linux kernel.

v2 -> v3:

IB/mlx5: Move '&umr_context' into helper fn
IB/mthca: Restructure mthca_cmd.c to manage free_head
IB/hns: Restructure hns_roce_cmd.c to manage free_head
IB/core: Convert completion to wait_event
IB/mlx5: Simplify completion into a wait_event

Thanks,
Binoy
