From 95af120e601671e6819ca97b78a1879d4ab0d853 Mon Sep 17 00:00:00 2001

Subject: [PATCH] CPU: The  API change to EventWrapper did not get propagated
 to the entirety of TimingSimpleCPU. The constructor no-longer schedules an
 event at construction and the implict conversion between int and bool was
 allowing the old code to compile without warning.
