Andrew Bresticker a669efc4a3 MIPS: Add hook to get C0 performance counter interrupt ... The hardware perf event driver and oprofile interpret the global cp0_perfcount_irq differently: in the hardware perf event driver it is an offset from MIPS_CPU_IRQ_BASE and in oprofile it is the actual IRQ number. This still works most of the time since MIPS_CPU_IRQ_BASE is usually 0, but is clearly wrong. Since the performance counter interrupt may vary from platform to platform like the C0 timer interrupt, add the optional get_c0_perfcount_int hook which returns the IRQ number of the performance counter. The hook should return < 0 if the performance counter interrupt is shared with the timer. If the hook is not present, the CPU vector reported in C0_IntCtl (cp0_perfcount_irq) is used.
