I assumed that I forgot that piece during backporting but infact it was not part of the original patch.
--- a/include/linux/irq.h +++ b/include/linux/irq.h @@ -388,6 +388,7 @@ extern int no_irq_affinity; */ extern void handle_level_irq(unsigned int irq, struct irq_desc *desc); extern void handle_fasteoi_irq(unsigned int irq, struct irq_desc *desc); +extern void handle_fasteoi_late_irq(unsigned int irq, struct irq_desc *desc); extern void handle_edge_irq(unsigned int irq, struct irq_desc *desc); extern void handle_edge_eoi_irq(unsigned int irq, struct irq_desc *desc); extern void handle_simple_irq(unsigned int irq, struct irq_desc *desc);
One side note: Since we need to specify IRQCHIP_EOI_THREADED and handle_fasteoi_late_irq() as the handler, would it be easily doable to use the handle_fasteoi_irq() handler and skip the EOI in the threaded mode? But if it creates a mess then leave it as it is.
