powerpc/ptrace: Preserve previous TM fprs/vsrs on short regset write
Ensure that if userspace supplies insufficient data to PTRACE_SETREGSET to fill all the check pointed registers, the thread's old check pointed registers are preserved. Fixes: 9d3918f7c0e5 ("powerpc/ptrace: Enable support for NT_PPC_CVSX") Fixes: 19cbcbf75a0c ("powerpc/ptrace: Enable support for NT_PPC_CFPR") Cc: stable@vger.kernel.org # v4.8+ Signed-off-by: Dave Martin <Dave.Martin@arm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
