+Subject: Revert "perf map: Fix dso->nsinfo refcounting"
+
+From: Arnaldo Carvalho de Melo <acme@redhat.com>
+
+commit 9bac1bd6e6d36459087a728a968e79e37ebcea1a upstream.
+
+This makes 'perf top' abort in some cases, and the right fix will
+involve surgery that is too much to do at this stage, so revert for now
+and fix it in the next merge window.
+
+This reverts commit 2d6b74baa7147251c30a46c4996e8cc224aa2dc5.
