Hi! Recently I have been investigating some strange migration problems on s390x. It turned out under certain circumstances vhost_net corrupts avail.idx by using wrong endianness. I managed to track the problem down (I'm pretty sure). It boils down to the following. When stopping vhost userspace (QEMU) calls vhost_net_set_backend with the fd argument set to -1, this leads to is_le being

Aaron Plattner (11): Bug #12015: Use the right offsets in the dst arguments of pixman_blt. stride is in FbBits-sized chunks, but xoff is not. Bump video driver ABI for pci-rework. Set noCompositeExtension to TRUE when failing to initialize the extension (e.g. when Xinerama is enabled). Don't segfault on shutdown if we never managed to connect to dbus.
