DRM's fbdev console uses regular load and store operations to update framebuffer memory. The bochs driver on sparc64 requires the use of I/O-specific load and store operations. We have a workaround, but need a long-term solution to the problem. This patchset changes GEM's vmap/vunmap interfaces to forward pointers of type struct dma_buf_map and updates the generic fbdev emulation to use
