Subject: [PATCH] target/arm: Add ARMFault_UnsuppAtomicUpdate
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

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.
