From f4166c54bfe04f64603974058e44fbd7cfef0ccc Mon Sep 17 00:00:00 2001 From: Markus Metzger Date: Sun, 9 Nov 2008 14:29:21 +0100 Subject: x86, bts: DS and BTS initialization Impact: widen BTS/PEBS ptrace enablement to more CPU models Move BTS initialisation out of an #ifdef CONFIG_X86_64 guard. Assume core2 BTS and DS layout for future models of family 6 processors.
