*	alpha: Override READ_ONCE() with barriered implementation	Will Deacon	2020-07-21	1	-0/+35
	Rather then relying on the core code to use smp_read_barrier_depends() as part of the READ_ONCE() definition, instead override __READ_ONCE() in the Alpha code so that it generates the required mb() and then implement smp_load_acquire() using the new macro to avoid redundant back-to-back barriers from the generic implementation.
