From 7eb68a2a0519a77b93184c695d4d293c92dc2286 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Wed, 11 Feb 2015 16:40:58 +0100 Subject: [PATCH] ARM: BCM5301X: Ignore another (BCM4709 specific) fault code MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 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.
