+From c3290668646b767058e55b29f7b8f4be4af2e660 Mon Sep 17 00:00:00 2001

+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.
