b41e29398a [PATCH] x86_64: 386/x86-64 Further AMD dual core fixes
- Remove duplicated ifdef
- Make core_id match what Intel uses
- Initialize phys_proc_id correctly for non DC case
- Handle non power of two core numbers.

Fixes for both i386 and x86-64

a158608bf4 [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.

1cff94c6fe [PATCH] fix subarch breakage in amd dual core updates
The patch to arch/i386/kernel/cpu/amd.c relies on the variable
cpu_core_id which is defined in i386/kernel/smpboot.c.  This means it is
only present if CONFIG_X86_SMP is defined, not CONFIG_SMP (alternative
SMP harnesses won't have it, which is why it breaks voyager).

635186447d [PATCH] x86_64: Final support for AMD dual core
Clean up the code greatly.  Now uses the infrastructure from the Intel dual
core patch Should fix a final bug noticed by Tyan of not detecting the nodes
correctly in some corner cases.

Patch for x86-64 and i386

3dd9d51484 [PATCH] x86_64: add support for Intel dual-core detection and displaying
Appended patch adds the support for Intel dual-core detection and displaying
the core related information in /proc/cpuinfo.  

It adds two new fields "core id" and "cpu cores" to x86 /proc/cpuinfo and the
"core id" field for x86_64("cpu cores" field is already present in x86_64).

Number of processor cores in a die is detected using cpuid(4) and this is
documented in IA-32 Intel Architecture Software Developer's Manual (vol 2a)
(http://developer.intel.com/design/pentium4/manuals/index_new.htm#sdm_vol2a)

This patch also adds cpu_core_map similar to cpu_sibling_map.

Slightly hacked by AK.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
