Sorry, I'm not yet familiar with the community call process. If this
isn't for technical topic, please feel free to disregard my message.
BTY, this patch isn't limited to virtio. The load/store functions are
intended to handle various use cases across different architectures.
This might also serve as a good example for Philippe's topic: "How to
merge a series that touches many subsystems, with most reviews already
done but a few maintainers still not responding."
Thanks,
