From 87d8354de3560eb705bcee83142d775f703177a6 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Wed, 2 Apr 2014 11:41:58 +0200 Subject: PPC: openpic_kvm: Filter memory events properly Commit 6f1834a2b exposed a bug in openpic_kvm where we don't filter for memory events that only happen to the region we want to know events about. Add proper filtering, fixing the e500plat target with KVM.
