From 67317c2689567c24d18e0dd43ab6d409fd42dc6e Mon Sep 17 00:00:00 2001 From: Sudeep KarkadaNagesha Date: Thu, 7 Nov 2013 15:25:44 +0000 Subject: ARM64: /proc/interrupts: display IPIs of online CPUs only The non-IPI interrupts are displayed only for the online cpus from show_interrupts in kernel/irq/proc.c before calling arch_show_interrupts(). As a result, the column headers and the IPI count don't match if any CPU is offline. This patch fixes show_ipi_list to display IPIs for online CPUs only.
