The Exynos4412 has 4 cpus and each has a performance counter.
Thus, we should define 4 interrupts which are combined by irq-combiner for arm
pmu.

Tested on Exynos4412 based Origen-Quad board. You would required to
rebase it on latest code though.

You took old patch which I cannot remember now:) Actually, arm-pmu support
for exynos4412 was already merged in the latest code.[1]. I sent a clean-up
patch recently[2]. It could be more readable for exynos4412.
Thanks.

I realized that a little late. I have replied to the new patch with my
