This adds support for the performance monitor hardware on the MPC7450 family of processors (7450, 7451, 7455, 7447/7457, 7447A, 7448), used in the later Apple G4 powermacs/powerbooks and other machines. These machines have 6 hardware counters with a unique set of events which can be counted on each counter, with some events being available on multiple counters. Raw event codes for these processors are (PMC << 8) + PMCSEL. If PMC is non-zero then the event is that selected by the given PMCSEL value for that PMC (hardware counter). If PMC is zero then the event selected is one of the low-numbered ones that are common to several PMCs. In this case PMCSEL must be <= 22 and the event is what that PMCSEL value would select on PMC1 (but it may be placed any other PMC that has the same event for that PMCSEL value). For events that count cycles or occurrences that exceed a threshold, the threshold requested can be specified in the 0x3f000 bits of the raw event codes. If the event uses the threshold multiplier bit and that bit should be set, that is indicated with the 0x40000 bit of the raw event code. This fills in some of the generic cache events. Unfortunately there are quite a few blank spaces in the table, partly because these processors tend to count cache hits rather than cache accesses.
