[PATCH] x86_64/i386: fix defaults for physical/core id in /proc/cpuinfo
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.
