File 0103-include-revert-part-of-the-linux-he.patch of Package qemu-linux-user.20748

Subject: include: revert part of the linux header update

It's problematic to include the recent linux header for the
virtio-balloon device because it extends the size of the
virtio_balloon_config structure, which our older qemu code relies on for
determining the virtio-ballon device config size. This change breaks
migration.

Revert this portion of the linux header update to maintain the previous
config size for this device. (bsc#1156642)
