Subject: [Qemu-devel] [PATCH v1 3/6] s390x/tcg: make lura(g) use the new _real mmu.
Date: Tue, 26 Sep 2017 20:33:15 +0200	[thread overview]
Message-ID: <20170926183318.12995-4-david@redhat.com> (raw)
In-Reply-To: <20170926183318.12995-1-david@redhat.com>

Looks like, lurag was not loading 64bit but only 32bit.

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