Andrea Parri ab4af60534 riscv/barrier: Define __smp_{mb,rmb,wmb} ... Introduce __smp_{mb,rmb,wmb}, and rely on the generic definitions for smp_{mb,rmb,wmb}. A first consequence is that smp_{mb,rmb,wmb} map to a compiler barrier on !SMP (while their definition remains unchanged on SMP). As a further consequence, smp_load_acquire and smp_store_release have "fence rw,rw" instead of "fence iorw,iorw".
