ARM: 8789/1: signal: copy registers using __copy_to_user()
Commit 5ca451cf6ed04443774bbb7ee45332dafa42e99f upstream.
When saving the ARM integer registers, use __copy_to_user() to
copy them into user signal frame, rather than __put_user_error().
This has the benefit of disabling/enabling PAN once for the whole copy
intead of once per write.
