Pull virtio updates from Michael Tsirkin:

 - vdpa generic device type support

 - more virtio hardening for broken devices (but on the same theme,
   revert some virtio hotplug hardening patches - they were misusing
   some interrupt flags and had to be reverted)

 - RSS support in virtio-net

 - max device MTU support in mlx5 vdpa

 - akcipher support in virtio-crypto

 - shared IRQ support in ifcvf vdpa

 - a minor performance improvement in vhost

 - enable virtio mem for ARM64

 - beginnings of advance dma support

 - cleanups, fixes all over the place
