/*
 * Contains default mappings for irq_cpustat_t, used by almost every
 * architecture.  Some arch (like s390) have per cpu hardware pages and
 * they define their own mappings for irq_stat.

/*
 * Simple wrappers reducing source bloat.  Define all irq_stat fields
 * here, even ones that are arch dependent.  That way we get common
 * definitions instead of differing sets for each arch.
