NAME
       struct_irq_common_data - per irq data shared by all irqchips

SYNOPSIS
       struct irq_common_data {
         unsigned int __private state_use_accessors;
       #ifdef CONFIG_NUMA
         unsigned int node;
       #endif
         void * handler_data;
         struct msi_desc * msi_desc;
         cpumask_var_t affinity;
       #ifdef CONFIG_GENERIC_IRQ_IPI
         unsigned int ipi_offset;
       #endif
       };

MEMBERS
       state_use_accessors
           status information for irq chip functions. Use accessor functions to deal with it

       node
           node index useful for balancing

       handler_data
           per-IRQ data for the irq_chip methods

       msi_desc
           MSI descriptor

       affinity
           IRQ affinity on SMP. If this is an IPI related irq, then this is the mask of the CPUs
           to which an IPI can be sent.

       ipi_offset
           Offset of first IPI target cpu in affinity. Optional.
