From f8a25db47ebc11fe228735d916e480d4b2ebe611 Mon Sep 17 00:00:00 2001 From: Russell Currey Date: Tue, 15 Mar 2016 21:14:12 +1100 Subject: [PATCH] powerpc/powernv: Use the "unknown" checkstop type as a fallback The HMI code knows about three types of errors: CORE, NX and UNKNOWN. If OPAL were to add a new type, it would not be handled at all since there is no fallback case. Instead of explicitly checking for UNKNOWN, treat any checkstop type without a handler as unknown.
