From 591bd8e7b4c8b9246d7a1c81ffbd28e35dc5de4e Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Tue, 17 Aug 2010 22:08:39 +0200 Subject: KVM: PPC: Enable napping only for Book3s_64 Before I incorrectly enabled napping also for BookE, which would result in needless dcache flushes. Since we only need to force enable napping on Book3s_64 because it doesn't go into MSR_POW otherwise, we can just #ifdef that code to this particular platform.
