Date: Thu, 16 Jul 2009 20:05:39 -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 14/21] Blackfin: fix handling of IPEND in interrupt context save From: Robin Getz <robin.getz@...log.com> The interrupt context save logic incorrectly stored the address of the IPEND register rather than its value due to a missing dereference. While we're here, also enable this code for all kernel debugging scenarios and not just when KGDB is enabled.
