Hi all, Now the irq core supports hierarchy irq and stacked irqchips, so there may be multiple irq_datas associated with the same irq. But some fields in struct irq_data are per-irq instance and duplicating those fields into multiple irq_data may cause troubles. So this patch introduces a new data structure 'struct irq_common_data' to host per-irq instance data fields, and struct irq_data will only host per-chip data fields after the conversion. It's based on tip/x86/apic plus these two patches at: https://www.mail-archive.com/linux-kernel@xxxxxxxxxxxxxxx/msg879700.html And it passes Fengguang's zeroday test suite. Thanks!
