This is a note to let you know that I have just added a patch titled x86: Eliminate irq_mis_count counted in arch_irq_stat to the linux-3.5.y-queue branch of the 3.5.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.5.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.5.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 7fed304cba758bd5cc309e23010f7d824918fd10 Mon Sep 17 00:00:00 2001 From: Li Fei <fei.li@intel.com> Date: Fri, 26 Apr 2013 20:50:11 +0800 Subject: [PATCH] x86: Eliminate irq_mis_count counted in arch_irq_stat commit f7b0e1055574ce06ab53391263b4e205bf38daf3 upstream. 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.
