DRM client buffers are permanently mapped throughout their lifetime. This prevents us from using generic framebuffer emulation for devices with small dedicated video memory, such as ast or mgag200. With fb buffers permanently mapped, such devices often won't have enough space left to display other content (e.g., X11). This patch set introduces unmappable DRM client buffers for framebuffer
