From 5a943617ef52e9f79cd7cf437aad8870be27aabb Mon Sep 17 00:00:00 2001 From: John Kacur Date: Thu, 8 Oct 2009 17:20:15 +0200 Subject: x86, cpuid: Simplify the code in cpuid_open Peter picked up my patch for tip/x86/cpu that removes the bkl in cpuid_open. Ingo subsequently merged that into tip/master. This patch folds back in tglx's 55968ede164ae523692f00717f50cd926f1382a0 to my patch that removed the bkl. This simplifies the code, and makes it consistent with the changes to kill the bkl in msr.c as well. Originally-by: Thomas Gleixner Signed-off-by: John Kacur Signed-off-by: H.
