Hi Linus,

These are the proposed RDMA patches for 4.21.

There is a conflict with the net tree merged in 4.20 and the Mellanox shared
tree. DaveM has a resolution for this in his net-next tree already, but if you
merge RDMA first, here is the resolution:

  struct mlx5_ifc_flow_table_eswitch_cap_bits {
-       u8      reserved_at_0[0x1c];
-       u8      fdb_multi_path_to_table[0x1];
-       u8      reserved_at_1d[0x1];
+       u8      reserved_at_0[0x1a];
        u8      multi_fdb_encap[0x1];
-       u8      reserved_at_1f[0x1e1];
+       u8      reserved_at_1b[0x1];
+       u8      fdb_multi_path_to_table[0x1];
+       u8      reserved_at_1d[0x3];
+
+       u8      reserved_at_20[0x1e0];

There is also a conflict in -next with the NFS tree, in this case the correct
resolution is to continue to delete net/sunrpc/xprtrdma/fmr_ops.c

Things got a bit busy in a rush up to the US holiday season, so we may see a
busier early -rc cycle, I've seen a few thing that suggest there are some new
bugs now. The major changes to the uapi will hopefully encourage all the
driver maintainer do to early testing.

This PR is generated off v4.20, typically we've waited until net-next is
merged. For this reason you will see below a large number of patches that
duplicate ones in net-next from the Mellanox shared branch.

The tag for-linus-merged with my merge resolution to your tree is also
available to pull.

  RDMA/srpt: Use kmem_cache_free() instead of kfree() (2018-12-22 16:07:47 -0700)

----------------------------------------------------------------
4.21 merge window pull request

This has been a fairly typical cycle, with the usual sorts of driver
updates. Several series continue to come through which improve and
modernize various parts of the core code, and we finally are starting to
get the uAPI command interface cleaned up.

- Various driver fixes for bnxt_re, cxgb3/4, hfi1, hns, i40iw, mlx4, mlx5,
  qib, rxe, usnic

- Rework the entire syscall flow for uverbs to be able to run over
  ioctl(). Finally getting past the historic bad choice to use write()
  for command execution

- More functional coverage with the mlx5 'devx' user API

- Start of the HFI1 series for 'TID RDMA'

- SRQ support in the hns driver

- Support for new IBTA defined 2x lane widths

- A big series to consolidate all the driver function pointers into
  a big struct and have drivers provide a 'static const' version of the
  struct instead of open coding initialization

- New 'advise_mr' uAPI to control device caching/loading of page tables

- Support for inline data in SRPT

- Modernize how umad uses the driver core and creates cdev's and sysfs
  files

- First steps toward removing 'uobject' from the view of the drivers
