Subject: [PATCH 0/2] Fix failure to hot add memory

Hi Michael,
The following two patches are a fixing a failure to update the hardware
with the updated used index. This results in a failure to to hot add
memory to the guest which results in a memory map update and teardown
and re-create of the resources.

The first patch just removes unnecessary code. The second on is the
actual fix.

Eli Cohen (2):
  vdpa/mlx5: Avoid unnecessary query virtqueue
  vdpa/mlx5: Restore the hardware used index after change map
