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.
