+Subject: [PATCH soc] ARM: BCM5301X: Ignore another (BCM4709 specific) fault
+ code
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Broadcom ARM devices seem to generate some fault once per boot. We
+already have an ignoring handler for BCM4707/BCM4708, but BCM4709
+generates different code.
