[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. This will fix problems with the powernow-k8 driver
on dual core systems and general misdetection of AMD dual core.

Looks like a mismerge somewhere.  Also add a warning comment.
