From 8b699616f399b58071cda41e5a1125d8480ac982 Mon Sep 17 00:00:00 2001 From: Andrea Parri Date: Sat, 1 Dec 2018 01:01:56 +0100 Subject: riscv, atomic: Add #define's for the atomic_{cmp,}xchg_*() variants If an architecture does not define the atomic_{cmp,}xchg_*() variants, the generic implementation defaults them to the fully-ordered version. riscv's had its own variants since "the beginning", but it never told (#define-d these for) the generic implementation: it is time to do so.
