+Subject: Revert "perf tools: Decompress kernel module when reading DSO data"
+
+From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
+
+This reverts commit e2d054998b151e85b6305aa72264f67097bd78e9 which is
+commit 1d6b3c9ba756a5134fd7ad1959acac776d17404b upstream.
+
+It breaks the build, so obviously none of us actually tested it :(
