Merge branch 'mlx5-next' of git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux into HEAD

mstsirkin · mstsirkin · commit 0a9d74d1f01e · 2020-08-05T18:32:05.000-04:00
Merge shared code that's necessary for mlx5 vdpa bits to build.

The branch itself includes a small number of patches and is also
independently merged by a couple of other trees.
That shouldn't cause any conflicts by itself.

Saeed Mahameed &lt;saeedm@mellanox.com&gt; says:

---

mlx5-next is a very small branch based on a very early rc that includes
mlx5 shared stuff between rdma and net-next, and now virtio as well.
