Based on original patches by Rusty Russell, Thomas Huth and Cornelia Huck. Note: at this time, we do not negotiate this feature bit in core, drivers have to declare VERSION_1 support explicitly. After all drivers are converted, we will be able to move VERSION_1 to core and drop it from all drivers. Signed-off-by: Michael S. Tsirkin <mst at redhat.com> Reviewed-by: Cornelia Huck

Extend features to 64 bit so we can use more transport bits. Future patches add two new feature bits which would exhaust the supply of transport feature bits, so let's add bit 31 to tell the guest that there are now 64 worth of features. For PCI this also changes the config layout. Signed-off-by: Michael S. Tsirkin <mst at redhat.com> --- drivers/lguest/lguest_device.c | 8
