4.9-stable review patch. If anyone has any objections, please let me know. ------------------ From: Dave Martin <Dave.Martin@xxxxxxx> commit fd7c99142d77dc4a851879a66715abf12a3193fb upstream. Ensure that if userspace supplies insufficient data to PTRACE_SETREGSET to fill all the registers, the thread's old registers are preserved.
