From f4800b1f4d23156e9080a08d6114e5d8bb767964 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Tue, 7 Aug 2012 10:24:14 +0200 Subject: [PATCH] KVM: PPC: Expose SYNC cap based on mmu notifiers Semantically, the "SYNC" cap means that we have mmu notifiers available. Express this in our #ifdef'ery around the feature, so that we can be sure we don't miss out on ppc targets when they get their implementation.
