[Qemu-devel] [PATCH] virtio: 64bit features fixups.


From: Gerd Hoffmann
Subject: [Qemu-devel] [PATCH] virtio: 64bit features fixups.
Date: Wed, 3 Jun 2015 14:36:57 +0200

Commit "019a3ed virtio: make features 64bit wide" missed a few changes,
as I've noticed while trying to rebase the virtio-1 branch to latest
master.
