Ravikiran G Thirumalai 4004c69ad6 Avoid too many remote cpu references due to /proc/stat ... Optimize show_stat to collect per-irq information just once. On x86_64, with newer kernel versions, kstat_irqs is a bit of a problem. On every call to kstat_irqs, the process brings in per-cpu data from all online cpus. Doing this for NR_IRQS, which is now 256 + 32 * NR_CPUS results in (256+32*63) * 63 remote cpu references on a 64 cpu config. Considering the fact that we already compute this value per-cpu, we can save on the remote references as below.
