Merge branch 'mlx5-rd-sgl' into rdma.git for-next 

From Yamin Friedman:

====================
This series from Yamin implements long standing "TODO" existed in rw.c. It
allows the driver to specify a cut-over point where it is faster to build
a lkey MR rather than do a large SGL for RDMA READ operations.

mlx5 HW gets a notable performane boost by switching to MRs.
====================

Based on the mlx5-next branch from
git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux for
dependencies

* branch 'mlx5-rd-sgl': (3 commits)
  RDMA/mlx5: Add capability for max sge to get optimized performance
  RDMA/rw: Support threshold for registration vs scattering to local pages
  net/mlx5: Expose optimal performance scatter entries capability

Timestamps
----------
The kernel embeds a timestamp in two places:
The kernel embeds timestamps in three places:
* The version string exposed by ``uname()`` and included in
``/proc/version``
* File timestamps in the embedded initramfs
By default the timestamp is the current time. This must be overridden
using the `KBUILD_BUILD_TIMESTAMP`_ variable. If you are building
from a git commit, you could use its commit date.
* If enabled via ``CONFIG_IKHEADERS``, file timestamps of kernel
headers embedded in the kernel or respective module,
exposed via ``/sys/kernel/kheaders.tar.xz``
By default the timestamp is the current time and in the case of
``kheaders`` the various files' modification times. This must
be overridden using the `KBUILD_BUILD_TIMESTAMP`_ variable.
If you are building from a git commit, you could use its commit date.
The kernel does *not* use the ``__DATE__`` and ``__TIME__`` macros,
and enables warnings if they are used. If you incorporate external
