From a9c59264690aea9d0df2d2d76683bc39ec6b7288 Mon Sep 17 00:00:00 2001 From: Paul Mackerras Date: Thu, 20 Oct 2005 17:09:51 +1000 Subject: [PATCH] powerpc: Move smp_mpic_message_pass into mpic.c Having it here rather than in arch/ppc64/kernel/smp.c means that we can use it on 32-bit SMP systems easily with ARCH=powerpc.
