From: Greg Kroah-Hartman
Date: Mon Sep 15 2014 - 15:27:18 EST


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

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

From: Alex Smith <alex@xxxxxxxxxxxxxxxx>

commit 65768a1a92cb12cbba87588927cf597a65d560aa upstream.

task_user_regset_view() should test for TIF_32BIT_REGS in the flags of
the specified task, not of the current task.
