ARM: 8643/3: arm/ptrace: Preserve previous registers for short regset write
commit 228dbbfb5d77f8e047b2a1d78da14b7158433027 upstream.
Ensure that if userspace supplies insufficient data to
PTRACE_SETREGSET to fill all the registers, the thread's old
registers are preserved.
Fixes: 5be6f62b0059 ("ARM: 6883/1: ptrace: Migrate to regsets framework")
