[PATCHv2 02/10] ARM: vic: MULTI_IRQ_HANDLER handler

[Zoltan Devai]

2011/9/28 Jamie Iles <jamie at jamieiles.com>:
> Add a handler for the VIC that is suitable for MULTI_IRQ_HANDLER

>
> v2:     - allow the handler be used for !CONFIG_OF
>        - use irq_domain_to_irq()

__exception_irq_entry doesn't compile with CONFIG_FUNCTION_GRAPH_TRACER enabled.
Either this file, or arch/arm/include/asm/system.h needs an #include
<linux/ftrace.h>
