From b28503a3fe6400757817e4460090f96bc1b9d6e7 Mon Sep 17 00:00:00 2001 From: Thomas Richter Date: Fri, 15 Sep 2017 09:14:03 +0200 Subject: perf test: Fix vmlinux failure on s390x On s390x perf test 1 failed. It turned out that commit 4a084ecfc821 ("perf report: Fix module symbol adjustment for s390x") was incorrect. The previous implementation in dso__load_sym() is also suitable for s390x. Therefore this patch undoes commit 4a084ecfc821.
