From f06a93fffac579694b0bb67fa81154b75b99f26e Mon Sep 17 00:00:00 2001 From: Len Brown Date: Fri, 15 Jul 2011 17:37:15 -0400 Subject: x86, intel, power: Correct the MSR_IA32_ENERGY_PERF_BIAS message commit 17edf2d79f1ea6dfdb4c444801d928953b9f98d6 upstream. Fix the printk_once() so that it actually prints (didn't print before due to a stray comma.)
