From 1c2ac3fde3e35279958e7b0408e2dcf866465301 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Mon, 14 May 2012 15:25:34 +0200 Subject: [PATCH] perf/x86: Fix wrmsrl() debug wrapper Move the wrmslr() debug wrapper to the common header now that all the include games are gone. Also clean it up a bit to avoid multiple evaluation of the argument.
