entry_Add_enter_from_user_mode_wrapper

entry_Add_enter_from_user_mode_wrapper

To be called from architecture specific code if the combo interfaces are
not suitable. It simply calls __enter_from_user_mode(). This way
__enter_from_user_mode will still be inlined because it is declared static
__always_inline.
