Subject: [PATCH] drm/savage: Do not add framebuffer and aperture maps
Since multiple framebuffer maps are not supported any longer (commit
41c2e75e60200a860a74b7c84a6375c105e7437f) these maps would be broken,
and they are not used by the drm anyway.
Leave it to userspace to create one working map instead.
Signed-off-by: Tormod Volden <debian.tormod@xxxxxxxxx>

And if we are absolutely sure that we do not want to support multiple
framebuffers maps, I would instead suggest this change to the savage
driver, which at least allows userspace to work around it.
