 *

 * Preserve the reservation of the mmaping with the DRM core code, but

 * It is vital that we remove the page mapping if we have mapped a tiled

 * object through the GTT and then lose the fence register due to

 * resource pressure. Similarly if the object has been moved out of the

 * aperture, than pages mapped into userspace must be revoked. Removing the
