Title:
   IBM-iobrick patches for Ubuntu 20.04

Status in Ubuntu on IBM z Systems:
  Expired
Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Hi,

  The request is to backport 
  09689703d29a RDMA/mlx5: Do not race with mlx5_ib_invalidate_range during 
create and destroy
  with it the below list (divided to four sets) is required.

  most of the patches applied cleanly above focal tree four exceptions.

  1. 806b101b2bfa RDMA/mlx5: Use a dedicated mkey xarray for ODP
  2. b91e1751fbce RDMA/mlx5: Simplify how the MR cache bucket is located
  3. 1769c4c57548 RDMA/mlx5: Always remove MRs from the cache before destroying 
them
  4. b9358bdbc713 RDMA/mlx5: Fix locking in MR cache work queue
  the rejected hunks need to be manually applied.
  The rejected hunks are due to true<-->1 false<-->0 exchange added support for 
wc (b9358bdbc713) and other minor reasons.  

   set 0: Unrelated code cleanups (needed for applying  cleanly the mr cache 
set)
   https://patchwork.kernel.org/cover/11170991/
   909624d8db5b IB/cm: Use container_of() instead of typecast
   6f26b2ac699c IB/mlx5: Remove unnecessary else statement
   2d67c0798821 IB/mlx5: Remove unnecessary return statement
   4b2a67362e78 RDMA/mlx5: Group boolean parameters to take less space

   set 1: Rework the locking and datastructures for mlx5 implicit ODP
   https://patchwork.kernel.org/cover/11181509/
   46870b2391d5 RDMA/odp: Remove broken debugging call to invalidate_range
   09689703d29a RDMA/mlx5: Do not race with mlx5_ib_invalidate_range during 
create and destroy
   d561987f34f2 RDMA/mlx5: Do not store implicit children in the odp_mkeys 
xarray
   5256edcb98a1 RDMA/mlx5: Rework implicit ODP destroy
   b70d785d237c RDMA/mlx5: Avoid double lookups on the pagefault path
   3389baa831b6 RDMA/mlx5: Reduce locking in implicit_mr_get_data()
   423f52d65005 RDMA/mlx5: Use an xarray for the children of an implicit ODP
   54375e738295 RDMA/mlx5: Split implicit handling from pagefault_mr
   9162420dde49 RDMA/mlx5: Set the HW IOVA of the child MRs to their place in 
the tree
   c2edcd69351f RDMA/mlx5: Lift implicit_mr_alloc() into the two routines that 
call it
   3d5f3c54e7bc RDMA/mlx5: Rework implicit_mr_get_data
   74bddb3682f6 RDMA/mlx5: Delete struct mlx5_priv->mkey_table
   806b101b2bfa RDMA/mlx5: Use a dedicated mkey xarray for ODP
   50211ec9443f RDMA/mlx5: Split sig_err MR data into its own xarray
   fb985e278a30 RDMA/mlx5: Use SRCU properly in ODP prefetch

  
   set 2: Consolidate the mmu notifier interval_tree and locking (only first 
two patches from this set)
   https://patchwork.kernel.org/cover/11240081/
   99cb252f5e68 mm/mmu_notifier: add an interval tree notifier
   56f434f40f05 mm/mmu_notifier: define the header pre-processor parts even if 
disabled

  
   also needed for applying  mr cache set cleanly.
   03232cc43cff IB/mlx5: Introduce and use mkey context setting helper routine

   set 3: MR cache fixes and refactoring
