From 170a0bc3808909d8ea0f3f9c725c6565efe7f9c4 Mon Sep 17 00:00:00 2001 From: John Kacur Date: Wed, 7 Oct 2009 20:19:32 +0200 Subject: x86, cpuid: Remove the bkl from cpuid_open() Most of the variables are local to the function. It IS possible that for struct cpuinfo_x86 *c c could point to the same area. However, this is used read only. Signed-off-by: John Kacur LKML-Reference: Signed-off-by: H.
