| |
3.2-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.
