+          The Wait for Interrupt (WTINT) PALcall attempts to place the CPU

+ * The "generalized" performance events seem to really be a copy
+ * of the available events on x86 processors; the mapping to ARC
+ * events is not always possible 1-to-1. Fortunately, there doesn't
+ * seem to be an exact definition for these events, so we can cheat
+ * a bit where necessary.
+ *
+ * In particular, the following PERF events may behave a bit differently
+ * compared to other architectures:
+ *
+ * PERF_COUNT_HW_CPU_CYCLES
+ *      Cycles not in halted state
+ *
+ * PERF_COUNT_HW_REF_CPU_CYCLES
+ *      Reference cycles not in halted state, same as PERF_COUNT_HW_CPU_CYCLES
+ *      for now as we don't do Dynamic Voltage/Frequency Scaling (yet)
+ *
+ * PERF_COUNT_HW_BUS_CYCLES
+ *      Unclear what this means, Intel uses 0x013c, which according to
+ *      their datasheet means "unhalted reference cycles". It sounds similar
+ *      to PERF_COUNT_HW_REF_CPU_CYCLES, and we use the same counter for it.
+ *
+ * PERF_COUNT_HW_STALLED_CYCLES_BACKEND
+ * PERF_COUNT_HW_STALLED_CYCLES_FRONTEND
+ *      The ARC 700 can either measure stalls per pipeline stage, or all stalls
+ *      combined; for now we assign all stalls to STALLED_CYCLES_BACKEND
