From 97c95059848358f1577f471ec47cf68690f996e4 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Thu, 2 Aug 2012 15:10:00 +0200 Subject: KVM: PPC: PR: Use generic tracepoint for guest exit We want to have tracing information on guest exits for booke as well as book3s. Since most information is identical, use a common trace point.
