Subject: [PATCH v2 02/21] target/arm: Check aa32_pan in take_aarch32_exception(), not aa64_pan
Date: Fri, 14 Feb 2020 17:50:57 +0000
Message-ID: <20200214175116.9164-3-peter.maydell@linaro.org> (raw)
In-Reply-To: <20200214175116.9164-1-peter.maydell@linaro.org>

In take_aarch32_exception(), we know we are dealing with a CPU that
has AArch32, so the right isar_feature test is aa32_pan, not aa64_pan.
