Trace events

If you use the instrumented kernel to trace events in your system, you should be aware of these changes:

• Some kernel events have _NTO_TRACE_KERCALL64 ORed into the event type to indicate that the event includes 64-bit data types.
• There are 64-bit versions of some System class events:
  • _NTO_TRACE_SYS_IPI_64 — emitted when a interprocessor interrupt is received
  • _NTO_TRACE_SYS_MAPNAME_64 — emitted when dlopen() is called
