Subject: [PATCH v6 06/14] target/arm: Add ARMFault_UnsuppAtomicUpdate
Date: Mon, 24 Oct 2022 15:18:43 +1000	[thread overview]
Message-ID: <20221024051851.3074715-7-richard.henderson@linaro.org> (raw)
In-Reply-To: <20221024051851.3074715-1-richard.henderson@linaro.org>

This fault type is to be used with FEAT_HAFDBS when
the guest enables hw updates, but places the tables
in memory where atomic updates are unsupported.
