+Subject: [PATCH 1/2] libtraceevent: Fix build with binutils 2.35
+
+In binutils 2.35, 'nm -D' changed to show symbol versions along with
+symbol names, with the usual @@ separator.  When generating
+libtraceevent-dynamic-list we need just the names, so strip off the
+version suffix if present.

+Subject: [PATCH 2/2] perf cs-etm: Move definition of 'traceid_list' global
+ variable from header file
+
+The variable 'traceid_list' is defined in the header file cs-etm.h,
+if multiple C files include cs-etm.h the compiler might complaint for
+multiple definition of 'traceid_list'.
+
+To fix multiple definition error, move the definition of 'traceid_list'
+into cs-etm.c.
