-From c3290668646b767058e55b29f7b8f4be4af2e660 Mon Sep 17 00:00:00 2001
-From: Andrew G Morgan <morgan@kernel.org>
-Date: Thu, 02 Jan 2014 01:56:31 +0000
-Subject: Fix up the uapi/linux include scheme.
-
-In adopting this uapi header file (without kernel internals), I previously
-messed up on the apparent location of the files. Thanks to Tom Gundersen for
-the clarification. Also, delete the non-uapi copies of things since they
-are no longer needed to build the library and tools.
