3.6.11.4 stable review patch. If anyone has any objections, please let me know. ------------------ From: Li Fei [ Upstream commit f7b0e1055574ce06ab53391263b4e205bf38daf3 ] With the current implementation, kstat_cpu(cpu).irqs_sum is also increased in case of irq_mis_count increment. So there is no need to count irq_mis_count in arch_irq_stat, otherwise irq_mis_count will be counted twice in the sum of /proc/stat.
