Subject: [Qemu-devel] [PATCH v1 4/6] s390x/tcg: make stora(g) use the new _real mmu
Date: Tue, 26 Sep 2017 20:33:16 +0200	[thread overview]
Message-ID: <20170926183318.12995-5-david@redhat.com> (raw)
In-Reply-To: <20170926183318.12995-1-david@redhat.com>

As we properly handle the return address now, we can drop
potential_page_fault().
