[PATCH] i386: Move phys_proc_id/early intel workaround to correct function.
early_cpu_detect only runs on the BP, but this code needs to run on all CPUs. Looks like a mismerge somewhere. Also add a warning comment. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
