From a33532af18e7c0c775cf70a15dbc5602d371e880 Mon Sep 17 00:00:00 2001 From: Nicholas Piggin Date: Wed, 21 Sep 2016 17:44:06 +1000 Subject: [PATCH] powerpc/64s: Use a single macro for both parts of OOL exception Simple substitution. This is possible now that both parts of the OOL initial handler get linked into their correct location.
