This patchset replaces radeon's framebuffer emulation with the generic code from fb helpers. This reduces the driver size and complexity. As a nice side effect, it also reduces memory pressure on low-memory devices. Patches #1 and #2 add features to fbdev emulation to bring it on par with radeons code. Patch #4 adds internal pinning to vmap operations. This guarantess that the framebuffer BO is not relocated while being updated. Patch #5 and #6 replace radeon's framebuffer code with the generic helper with shadow buffering. All userspace mappings interact with the shadow buffer and the BO can be relocated an necessary. This allows to enable 32-bit colors on low-memory devices. Patches #3 and #7 are merely cleanups. Smoke tested with an AMD R5 (Oland) card by running the console and switching to/from Xorg and weston.
