It's not quite as bad as it seems. The infiniband tree itself builds,
the problem is the merged tree.
The Mellanox guys merged the "cleanup"
commit 0c7aac854f52
Author: Eli Cohen <eli@xxxxxxxxxxxxxxxxxx>

net/mlx5_core: Remove unused dev cap enum fields
These enumerations are not used so remove them.
Signed-off-by: Eli Cohen <eli@xxxxxxxxxxxx>
Signed-off-by: David S. Miller <davem@xxxxxxxxxxxxx>
through davem's tree, and then went ahead and used at least
MLX5_DEV_CAP_FLAG_ON_DMND_PG (which that patch removes) in patches
they merged through my tree.
I'll add a partial revert of that patch to my tree to get back the
now-used enum values.
- R.
