[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.

[RFC PATCH 0/2] ASID: Flush by ASID
Future AMD SVM supports a new feature called flush by ASID. The idea is to
allow CPU to flush TLBs associated with the ASID assigned to guest VM. So
hypervisor doesn''t have to reassign a new ASID in order to flush guest''s
VCPU. Please review it.
Thanks,
Wei

[PATCH RFC v2 2/4] vdpa/mlx5: implement .reset_map driver op
...virtio device reset. Leverage the
.reset_map callback to reset memory mapping, then the device
.reset routine can run free from having to clean up memory
mappings.

[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

[RFC PATCH 00/24] Control VQ support in vDPA
...art and stop device correctly (e.g for Live Migration).
This requies to isolate the memory mapping for control virtqueue
presented by vhost-vDPA to prevent guest from accesing it directly.
To achieve this, vDPA introduce two new abstractions:
- address space: identified through address space id (ASID) and a set
of memory mapping in maintained
- virtqueue group: the minimal set of virtqueues that must share an
address space
Device needs to advertise the following attributes to vDPA:

[PATCH v3 13/22] v2v: linux: Properly ignore rpm/dpkg-move-aside kernels.
The old virt-v2v code ignored boot kernels with names like
"/boot/vmlinuz-*.rpmsave". The transscribed code did not because the
Str module requires ‘|’ to be escaped as ‘\|’.
This changes the code to use PCRE and fixes it.

Ok that's the basic layout. Here's the low down - Each company will
have one dedicated channel for there company. The other 2 channels they
want to be set aside as rollover's (rotary). That is not an issue.
Where my concern is, how can I specify if they call Company A and
primary line is busy and it rolls over to one of the spare lines, how do
I designate which Auto Attendant is played. If it was certain channels
