+ * The "generalized" performance events seem to really be a copy

+ * 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
+ * and all pipeline flushes (e.g. caused by mispredicts, etc.) to
+ * STALLED_CYCLES_FRONTEND.
+ *
+ * We could start multiple performance counters and combine everything
+ * afterwards, but that makes it complicated.
+ *
+ * Note that I$ cache misses aren't counted by either of the two!

+ * Functions to disable system interrupts from backup-powered peripherals.
+ *
+ * The RTC and RTT-peripherals are generally powered by backup power (VDDBU)
+ * and are not reset on wake-up, user, watchdog or software reset. This means
+ * that their interrupts may be enabled during early boot (e.g. after a user
+ * reset).
+ *
+ * As the RTC and RTT share the system-interrupt line with the PIT, an
+ * interrupt occurring before a handler has been installed would lead to the
+ * system interrupt being disabled and prevent the system from booting.
