From f2d28e80bc6260c90396e9fc798d559775dbde23 Mon Sep 17 00:00:00 2001 From: Aaro Koskinen Date: Wed, 30 Sep 2015 15:57:55 +0300 Subject: bootchart: use get_proc_field and PROC_CPUINFO_MODEL Use get_proc_field and PROC_CPUINFO_MODEL to get the CPU type. Also don't fail if it missing, instead restore the old behaviour and print "Unknown". Fixes the following error seen with v225 on powerpc: Unable to read module name from cpuinfo.
