From 81e7bf1fe3b4c70180f8d9b1d89071c13f804002 Mon Sep 17 00:00:00 2001 Message-Id: <81e7bf1fe3b4c70180f8d9b1d89071c13f804002@dist-git> From: Andrea Bolognani Date: Tue, 11 Aug 2015 17:15:49 +0200 Subject: [PATCH] cpu: Rename {powerpc, ppc} => ppc64 (filesystem) The driver only supports VIR_ARCH_PPC64 and VIR_ARCH_PPC64LE. Just shuffling files around and updating the build system accordingly. No functional changes.
