Hi,
This small series fixes an issue reported in Gitlab [1] that
affects PowerPC big-endian and little-endian and probably all
other big-endians in the wild that might use 'ivshmem'.
It's not clear to me who is the maintainer/responsible for this device
(MAINTAINERS doesn't seem to have any 'ivhshmem' entries nor someone
that looks upon all hw/misc/* files) so I didn't add any CC in that
regard. 'qemu-ppc' is being copied for awareness since they are the
folks that are most likely being impacted by the bug.
