    ARC: IRQ: Do not use hwirq as virq and vice versa · 34e71e4c
    Yuriy Kolerov authored
    This came up when reviewing code to address missing IRQ affinity
    setting in AXS103 platform and/or implementing hierarchical IRQ domains
    
    - smp_ipi_irq_setup() callers pass hwirq but in turn calls
      request_percpu_irq() which expects a linux virq. So invoke
      irq_find_mapping() to do the conversion
      (also explicitify this in code by renaming the args appropriately)
    
    - idu_of_init()/idu_cascade_isr() were similarly using linux virq where
      hwirq is expected, so do the conversion using irqd_to_hwirq() helper
