From 52471c67ee2fa5ed6f700ef57bf27833c63b2192 Mon Sep 17 00:00:00 2001 From: Robert Richter Date: Mon, 6 Jul 2009 14:43:55 +0200 Subject: [PATCH] x86/oprofile: Modify initialization of num_virt_counters Models that do not yet support counter multiplexing have to setup num_virt_counters. This patch implements the setup from num_counters if num_virt_counters is not set. Thus, num_virt_counters must be setup only for multiplexing support.
