Subject: [PATCH 7/8] powerpc/pseries: use single macro for both parts of OOL exception
Date: Tue, 13 Sep 2016 13:08:45 +1000	[thread overview]
Message-ID: <20160913030846.29790-8-npiggin@gmail.com> (raw)
In-Reply-To: <20160913030846.29790-1-npiggin@gmail.com>

Simple substitution. This is possible now that both parts of the OOL
initial handler get linked into their correct location.
