Subject: [PATCH v2 50/55] hw/core/cpu: Add prctl-unalign-sigbus property for user-only
Date: Mon,  2 Aug 2021 18:14:38 -1000	[thread overview]
Message-ID: <20210803041443.55452-51-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210803041443.55452-1-richard.henderson@linaro.org>

Actually disabled for now.  Will enable for each cpu that
supports the feature.

Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
