Subject: [PULL 14/26] target/arm: Use get_phys_addr_with_struct in S1_ptw_translate
Date: Fri, 23 Jun 2023 13:31:23 +0100	[thread overview]
Message-ID: <20230623123135.1788191-15-peter.maydell@linaro.org> (raw)
In-Reply-To: <20230623123135.1788191-1-peter.maydell@linaro.org>

From: Richard Henderson <richard.henderson@linaro.org>

Do not provide a fast-path for physical addresses,
as those will need to be validated for GPC.
