Julien Thierry 73839798af ARM: 8790/1: signal: always use __copy_to_user to save iwmmxt context
When setting a dummy iwmmxt context, create a local instance and
use __copy_to_user both cases whether iwmmxt is being used or not.
This has the benefit of disabling/enabling PAN once for the whole copy
intead of once per write.
