Note: this will likely need to be rebased on the next upstream release, and a
similar changed will be required for the next 4.4 and 4.13 upstream imports as
well.

+Subject: [PATCH] Revert "UBUNTU: [Packaging] retpoline -- add safe usage hint
+ support"
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8

+This (partially) reverts commit 1e39020902132b3065bedf0a0c33031e89f9f57a.
+
+this modifies the upstream kernel build to call an Ubuntu script which
+we remove before building. it would also be required by any module
+builds afterwards and is not shipped by Ubuntu's kernel packages either.
