Subject: [PATCH 4.4 143/163] perf hists browser: Only offer symbol scripting when a symbol is under the cursor

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

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

From: Namhyung Kim <namhyung@...nel.org>

commit c221acb0f970d3b80d72c812cda19c121acf5d52 upstream.

When this feature was introduced a check was made if there was a
resolved symbol under the cursor, it got lost in commit ea7cd5923309
("perf hists browser: Split popup menu actions - part 2"), reinstate it.
