x86, apic: introduce io_apic_irq_attr
according to Ingo, io_apic irq-setup related functions have too many parameters with a repetitive signature. So reduce related funcs to get less params by passing a pointer to a newly defined io_apic_irq_attr structure. v2: io_apic_irq ==> irq_attr triggering ==> trigger v3: add set_io_apic_irq_attr [ Impact: cleanup ] Signed-off-by: Yinghai Lu <yinghai@kernel.org> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Jesse Barnes <jbarnes@virtuousgeek.org> Cc: Len Brown <lenb@kernel.org> LKML-Reference: <4A08ACD3.2070401@kernel.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
