These functions integrate the stack randomization. syscall_enter_from_user_mode_randomize_stack() has the advantage that the randomization happens early right after enter_from_user_mode(). In both cases also the overhead of get/put_cpu_var() in add_random_kstack_offset() is avoided. No functional change.
