Message-Id: <1247789146-18786-19-git-send-email-vapier@gentoo.org> Date: Thu, 16 Jul 2009 20:05:43 -0400 From: Mike Frysinger <vapier@...too.org> To: linux-kernel@...r.kernel.org Cc: uclinux-dist-devel@...ckfin.uclinux.org, Robin Getz <robin.getz@...log.com> Subject: [PATCH 18/21] Blackfin: work around anomaly 05000189 From: Robin Getz <robin.getz@...log.com> Similar to anomaly 05000281 but not as bad, we cannot return to the instruction causing a fault otherwise we'll trigger a second false exception. The system can still recover, but it isn't correct.
