Subject[PATCH 4.15 097/146] objtool: Use existing global variables for options
Date
4.15-stable review patch.  If anyone has any objections, please let me know.

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

From: Peter Zijlstra <peterz@infradead.org>

commit 43a4525f80534530077683f6472d8971646b0ace upstream.

Use the existing global variables instead of passing them around and
creating duplicate global variables.
