    Subject[PATCH 3.13 116/187] MIPS: ptrace: Test correct task's flags in task_user_regset_view()
    Date
    3.13.11.7 -stable review patch.  If anyone has any objections, please let me know.

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

    From: Alex Smith <alex@alex-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.
