Subject: [PATCH v2 10/13] target/s390x: Use user_or_likely in do_access_memset
Date: Tue, 9 Jul 2024 20:28:11 -0700 [thread overview]
Message-ID: <20240710032814.104643-11-richard.henderson@linaro.org> (raw)
In-Reply-To: <20240710032814.104643-1-richard.henderson@linaro.org>
Eliminate the ifdef by using a predicate that is
always true with CONFIG_USER_ONLY.
