Subject: [PATCH 8/9] powerpc/mce: Move 64-bit machine check code into mce.c
Date: Tue, 8 Aug 2017 16:39:24 +1000 [thread overview]
Message-ID: <1502174365-8293-8-git-send-email-mpe@ellerman.id.au> (raw)
In-Reply-To: <1502174365-8293-1-git-send-email-mpe@ellerman.id.au>
We already have mce.c which is built for 64bit and contains other parts
of the machine check code, so move these bits in there too.
Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
