+Subject: [PATCH] kernel: add support for gcc 6
+
+We're missing include/linux/compiler-gcc6.h which is required now
+because gcc branched off to v6 in trunk.
+
+Just copy the relevant bits out of include/linux/compiler-gcc4.h,
+no new code is added as of now.
+
+This fixes a build error when using gcc 6.
