Subject: [PATCH rdma-next v1 0/7] Use ib_umem_find_best_pgsz() for all umems

From: Leon Romanovsky <leonro@...dia.com>

Changelog:
v1:
 * Added patch for raw QP
 * Fixed commit messages
v0: https://lore.kernel.org/lkml/20201026132635.1337663-1-leon@kernel.org

-------------------------
>From Jason:

Move the remaining cases working with umems to use versions of
ib_umem_find_best_pgsz() tailored to the calculations the devices
requires.

Unlike a MR there is no IOVA, instead a page offset from the starting page
is possible, with various restrictions.

Compute the best page size to meet the page_offset restrictions.

Thanks

Jason Gunthorpe (7):
  RDMA/mlx5: Use ib_umem_find_best_pgoff() for SRQ
  RDMA/mlx5: Use mlx5_umem_find_best_quantized_pgoff() for WQ
  RDMA/mlx5: Directly compute the PAS list for raw QP RQ's
  RDMA/mlx5: Use mlx5_umem_find_best_quantized_pgoff() for QP
  RDMA/mlx5: mlx5_umem_find_best_quantized_pgoff() for CQ
  RDMA/mlx5: Use ib_umem_find_best_pgsz() for devx
  RDMA/mlx5: Lower setting the umem's PAS for SRQ
