[PATCH 0/5] Unmappable DRM client buffers for fbdev emulation
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 enougth space left to
display other content (e.g., X11).
