fix the following 'make headers_check' warning:

These functions are called only when bringing up the monarch cpu,
so it is safe to call them without taking the pdc spinlock. In the
future, this may become relevant for lockdep, since these functions were
taking spinlocks before start_kernel called the lockdep initializers.
