KVM: PPC: Move EXIT_DEBUG partially to tracepoints
We have a debug printk on every exit that is usually #ifdef'ed out. Using tracepoints makes a lot more sense here though, as they can be dynamically enabled. This patch converts the most commonly used debug printks of EXIT_DEBUG to tracepoints. Signed-off-by: Alexander Graf <agraf@suse.de>
