Subject: [PATCH v3 15/23] selftests/rseq: arm64: Template memory ordering and percpu access mode
Date:   Fri, 29 Jul 2022 15:02:17 -0400
Message-Id: <20220729190225.12726-16-mathieu.desnoyers@efficios.com>
In-Reply-To: <20220729190225.12726-1-mathieu.desnoyers@efficios.com>
References: <20220729190225.12726-1-mathieu.desnoyers@efficios.com>
Precedence: bulk

Introduce a rseq-arm64-bits.h template header which is internally
included to generate the static inline functions covering:

- relaxed and release memory ordering,
- per-cpu-id and per-vm-vcpu-id per-cpu data access.
