Subject: [PATCH 05/14] target/arm/ptw: Pass ARMSecurityState to regime_translation_disabled()
Date: Fri, 14 Jul 2023 16:46:39 +0100	[thread overview]
Message-ID: <20230714154648.327466-6-peter.maydell@linaro.org> (raw)
In-Reply-To: <20230714154648.327466-1-peter.maydell@linaro.org>

Plumb the ARMSecurityState through to regime_translation_disabled()
rather than just a bool is_secure.
