Subject: Use gcc atomics on aarch64/powerpc64le

X-Git-Url: http://git.lttng.org/?p=userspace-rcu.git;a=commitdiff_plain;h=3913336f0e763b4ab614aa6b6e41e20b481e50c3

Use gcc atomics on aarch64/powerpc64le

Currently there are two fairly recent architectures, which at the

moment can only be compiled with "gcc atomics" code path.

The two new architectures are (GNU Types):

* aarch64-linux-gnu (aka ARMv8, ARM64, AARCH64, etc)

* powerpc64le-linux-gnu
