+Date: Mon, 13 Oct 2014 15:51:05 -0700
+Subject: [PATCH 2/6] kernel: add support for gcc 5
+
+We're missing include/linux/compiler-gcc5.h which is required now
+because gcc branched off to v5 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 5.
