+ * Performance event support - hardware-specific disambiguation
+ *
+ * For now this is a compile-time decision, but eventually it should be
+ * runtime.  This would allow multiplatform perf event support for e300 (fsl
+ * embedded perf counters) plus server/classic, and would accommodate
+ * devices other than the core which provide their own performance counters.
