From 73bf1b62f561fc8ecb00e2810efe4fe769f4933e Mon Sep 17 00:00:00 2001 From: Markus Metzger Date: Thu, 5 Mar 2009 08:57:21 +0100 Subject: x86, pebs: correct qualifier passed to ds_write_config() from ds_request_pebs() ds_write_config() can write the BTS as well as the PEBS part of the DS config. ds_request_pebs() passes the wrong qualifier, which results in the wrong configuration to be written.
