From 2a3a2d66aa4e5abaf8f9222d21735321f02a00dc Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Sun, 30 Oct 2011 15:17:19 +0100 Subject: [S390] irqstats: split IPI interrupt accounting We use both the external call and emergency call IPIs to signal remote cpus. Therefore it makes sense to account them differently withing /proc/irqstats so we actually know what happened.
