IRQ time accounting reduces performance by 40% for some block storage

Android devices share a single kernel binary across device vendors.
Make IRQ time accounting configurable at boot time such that Android
vendors can decide individually whether or not to enable IRQ time
accounting.

Can anyone please help with reviewing this patch?

Thanks,
