[PATCH RFC v2 0/4] vdpa: decouple reset of iotlb mapping from device reset
In order to reduce needlessly high setup and teardown cost
of iotlb mapping during live migration, it's crucial to
decouple the vhost-vdpa iotlb abstraction from the virtio
device life cycle, i.e. iotlb mappings should be left
intact across virtio device reset [1]. For it to work, the
on-chip IOMMU parent device should implement a separate
.reset_map() operation callback to restore 1:1 DMA

[PATCH 0/2] vdpa/mlx5: Fixes for ASID handling
This patch series is based on Eugenio's fix for handling CVQs in
a different ASID [0].
The first patch is the actual fix.
The next 2 patches are fixing a possible issue that I found while
implementing patch 1. The patches are ordered like this for clarity.
