From 019a3edbb25f1571e876f8af1ce4c55412939e5d Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Mon, 1 Jun 2015 10:45:40 +0200 Subject: virtio: make features 64bit wide Make features 64bit wide everywhere. On migration a full 64bit guest_features field is sent if one of the high bits is set, in addition to the lower 32bit guest_features field which must stay for compatibility reasons. That way we send the lower 32 feature bits twice, but the code is simpler because we don't have to split and compose the 64bit features into two 32bit fields.
