[PATCH v2 14/21] target/arm: Use get_phys_addr_with_struct in S1_ptw_tra


From: Richard Henderson
Subject: [PATCH v2 14/21] target/arm: Use get_phys_addr_with_struct in S1_ptw_translate
Date: Mon, 20 Feb 2023 13:26:19 -1000

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