 2 * Performance event support - hardware-specific disambiguation
 3 *
 4 * For now this is a compile-time decision, but eventually it should be
 5 * runtime.  This would allow multiplatform perf event support for e300 (fsl
 6 * embedded perf counters) plus server/classic, and would accommodate
 7 * devices other than the core which provide their own performance counters.
