This patchset moves legacy, non-KMS driver state from struct drm_driver into struct drm_legacy_state. Only non-KMS drivers provide an instance of the latter structure. One special case is nouveau, which supports legacy interfaces. It also provides an instance of the legacy state if the legacy interfaces have been enabled (i.e., defines the config option CONFIG_NOUVEAU_LEGACY_CTX_SUPPORT) I
