Before this patch the checks of the parameters buffers for a TA where
required to be physical pointers. When a static TA is invoked from a
user TA the virtual addresses of the buffers aren't translated to
physical addresses as they will be translated back to the same virtual
address again. With this patch the parameters buffers are tagged as
containing virtual addresses allowing the checks to take that into
account.
