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.
And it passes Fengguang's zeroday test suite.
V1->V2:
1) Patch "net/mlx4: Cache irq_desc->affinity instead of irq_desc" is
still kept to avoid build failure. It may be dropped if Amir Vadai
changed related code.
2) Reorganize patches according to Thomas's suggestion.
3) Rename irq_data_get_msi() as irq_data_get_msi_desc().
Thanks!
Gerry
