5 * Contains default mappings for irq_cpustat_t, used by almost every
6 * architecture. Some arch (like s390) have per cpu hardware pages and
7 * they define their own mappings for irq_stat.
9 * Keith Owens <kaos@ocs.com.au> July 2000.
12 #include <linux/config.h>
15 * Simple wrappers reducing source bloat. Define all irq_stat fields
16 * here, even ones that are arch dependent. That way we get common
17 * definitions instead of differing sets for each arch.
