Subject: [Qemu-devel] [PATCH 5/5] target-arm: apply get_S1prot to get_phys_addr_v6
Date: Thu, 12 Feb 2015 16:05:07 +0100	[thread overview]
Message-ID: <1423753507-30542-6-git-send-email-drjones@redhat.com> (raw)
In-Reply-To: <1423753507-30542-1-git-send-email-drjones@redhat.com>

Now that we have get_S1prot, we can apply it to get_phys_addr_v6
for a minor code cleanup.
