Subject: [PATCH v2 06/15] linux-user/s390x: Fix sigcontext sregs value
Date: Wed, 28 Apr 2021 12:33:59 -0700 [thread overview]
Message-ID: <20210428193408.233706-7-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210428193408.233706-1-richard.henderson@linaro.org>
Using the host address of &frame->sregs is incorrect.
We need the guest address.
