qxl: store memory region and offset instead of pointer for guest slots
Store MemoryRegion and offset instead of a pointer for each qxl memory slot, so we can easily figure in which memory region an qxl object stored. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Message-id: 1466597244-5938-2-git-send-email-kraxel@redhat.com
