Some of the event counters are overloaded which makes it very difficult to interpret their values. Counter 0 is supposed to report CB1 interrupts but it can also count PMU_INT_WAITING_CHARGER events. Counter 1 is supposed to report GPIO interrupts but it can also count other events (depending upon the value of the PMU_INT_ADB bit). Disambiguate these statistics with dedicated counters for GPIO and CB1 interrupts. Comments in the MkLinux source code say that the type 0 and type 1 interrupts are model-specific. Label them as "unknown". This change to the contents of /proc/pmu/interrupts is by necessity visible in userland. However, packages which interact with the PMU (that is, pbbuttonsd, pmac-utils and pmud) don't open this file. AFAIK, user software has no need to poll these counters.
