Subject: [PULL 7/7] linux-user/aarch64: Use force_sig_fault()
Date: Fri, 24 Sep 2021 15:56:31 +0200 [thread overview]
Message-ID: <20210924135631.2067582-8-laurent@vivier.eu> (raw)
In-Reply-To: <20210924135631.2067582-1-laurent@vivier.eu>
From: Peter Maydell <peter.maydell@linaro.org>
Use the new force_sig_fault() function instead of setting up
a target_siginfo_t and calling queue_signal().
