Subject: [PATCH 3.13 116/187] MIPS: ptrace: Test correct task's flags in task_user_regset_view()

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

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

From: Alex Smith <alex@...x-smith.me.uk>

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.
