Subject: [PULL 09/27] tcg/s390x: Remove FAST_BCR_SER facility check
Date: Fri, 6 Jan 2023 23:51:00 -0800 [thread overview]
Message-ID: <20230107075118.1814503-10-richard.henderson@linaro.org> (raw)
In-Reply-To: <20230107075118.1814503-1-richard.henderson@linaro.org>
The fast-bcr-serialization facility is bundled into facility 45,
along with load-on-condition. We are checking this at startup.
