Subject: [PULL 7/9] target/s390x: Reduce s390_store_status() scope
Date: Fri, 10 Oct 2025 10:21:42 +0200 [thread overview]
Message-ID: <20251010082145.576222-8-thuth@redhat.com> (raw)
In-Reply-To: <20251010082145.576222-1-thuth@redhat.com>
From: Philippe Mathieu-Daudé <philmd@linaro.org>
s390_store_status() is only called within sigp.c,
move it and the SigpSaveArea structure definition
there where it belongs, with other SIGP handling
code.
