4.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Gerd Hoffmann <[email protected]> [ Upstream commit 71d3f6ef7f5af38dea2975ec5715c88bae92e92d ] virtio uses normal ram as backing storage for the framebuffer, so we should assign the address to new screen_buffer (added by commit 17a7b0b4d9749f80d365d7baff5dec2f54b0e992) instead of screen_base.
