+Subject: Kbuild: suppress packed-not-aligned warning for default setting only
+
+From: Xiongfeng Wang <xiongfeng.wang@linaro.org>
+
+commit 321cb0308a9e76841394b4bbab6a1107cfedbae0 upstream.
+
+gcc-8 reports many -Wpacked-not-aligned warnings. The below are some
+examples.
+
+./include/linux/ceph/msgr.h:67:1: warning: alignment 1 of 'struct
+ceph_entity_addr' is less than 8 [-Wpacked-not-aligned]
+ } __attribute__ ((packed));
+
+./include/linux/ceph/msgr.h:67:1: warning: alignment 1 of 'struct
+ceph_entity_addr' is less than 8 [-Wpacked-not-aligned]
+ } __attribute__ ((packed));
+
+./include/linux/ceph/msgr.h:67:1: warning: alignment 1 of 'struct
+ceph_entity_addr' is less than 8 [-Wpacked-not-aligned]
+ } __attribute__ ((packed));
+
+This patch suppresses this kind of warnings for default setting.
