[ 005/150] perf hists: Fix period symbol_conf.field_sep display

From: Greg Kroah-Hartman
Date: Tue Feb 26 2013 - 20:19:36 EST


3.8-stable review patch. If anyone has any objections, please let me know.

------------------

From: Jiri Olsa <jolsa@xxxxxxxxxx>

commit c0d246b85fc7d42688d7a5d999ea671777caf65b upstream.

Currently we don't properly display hist data with symbol_conf.field_sep
separator. We need to display either space or separator.
