From 02456169e03bcfcebd3115b2a54c1c4a6829c875 Mon Sep 17 00:00:00 2001 From: Hendrik Brueckner Date: Wed, 9 May 2012 16:27:40 +0200 Subject: [PATCH] s390/irq: split irq stats for cpu-measurement alert facilities CPU-measurement alerts are generated for different CPU-measurement facilities, for example, the sampling and counter facilities. Split the irq stats according to available facilities.
