Last round hopefully of cpu_core_id changes hopefully fow now:

- Always initialize cpu_core_id for all CPUs, even when no dual core setup
  is detected.  This prevents funny /proc/cpuinfo output

- Do the same with phys_proc_id[] even when no HyperThreading - dito.

- Use the CPU APIC-ID from CPUID 1 instead of the linux virtual CPU number
  to identify the core for AMD dual core setups.

Patch for i386/x86-64.
