ttm_fbdev_mmap() just doesn't work. It appears to work fine, mmap() returns success, but any attempt to actually access the mapping causes a SIGBUS. We can just use drm_gem_prime_mmap() instead. Almost. We have to copy over the start offset from the ttm_buffer_object vm_node to the drm_gem_object vm_node so the offset math in drm_gem_prime_mmap() works correctly for us even though we use ttm to manage our objects.
