From 6b98d0388a6c54a57f5f5da7256ccfb7f2484987 Mon Sep 17 00:00:00 2001 From: Robert Richter Date: Thu, 28 Jan 2010 16:50:45 +0100 Subject: [PATCH] oprofile/x86: remove node check in AMD IBS initialization commit 89baaaa98a10cad5cc8516c7208b02d9fc711890 upstream. Standard AMD systems have the same number of nodes as there are northbridge devices. However, there may kernel configurations (especially for 32 bit) or system setups exist, where the node number is different or it can not be detected properly. Thus the check is not reliable and may fail though IBS setup was fine. For this reason it is better to remove the check.
