	MULTIPROCESSOR sparc kernels since newlock2 merge have not
	worked with the assembler verions of mutex_spin_enter() and
	mutex_spin_exit().  for now, i have disabled them so that
	MULTIPROCESSOR kernels can function.


	re-enable __HAVE_MUTEX_SPIN_STUBS in
	sys/arch/sparc/include/mutex.h and the functions in

	and see kernel hang.


	yes please.
