3.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: "Michael S. Tsirkin" <mst@redhat.com> commit 910a578f7e9400a78a3b13aba0b4d2df16a2cb05 upstream. We copy head count to a 16 bit field, this works by chance on LE but on BE guest gets 0. Fix it up. Signed-off-by: Michael S.
