If anyone has any objections, please let me know. ------------------ From: Ruijie Li commit 28465227c80fe417b4013c432be1f3737cb9f9a3 upstream. The compat 64=>32 translation path handles XFRM_MSG_MAPPING, but xfrm_msg_min[] does not provide the native payload size for this message type. Add the missing XFRM_MSG_MAPPING entry so compat translation can size and translate mapping notifications correctly.
