I do wonder why we even need maintain pcie_pmu->cpumask

Can't we just use cpu_online_mask as appropiate instead?

Sorry, missed it yesterday.
It seems that cpumask is always same as cpu_online_mask, So do we need 
to reserve the cpumask sysfs interface?

I'm not saying that we don't require the cpumask sysfs interface. I am 
just asking why you maintain a separate cpumask, when, as I said, they 
seem the same.

Thanks,
