We're marking bit 0 of extended function 0x80000001 cpuid as PNI support on
AMD processors, when it actually denotes x87 FPU present. Patch for i386
and x86_64 below.

- broken sibling_map setup in x86_64
- grouping all the core and HT related cpuinfo fields.
We are reasonably sure that adding new cpuinfo fields after "siblings" field,
will not cause any app failure. Thats because today's /proc/cpuinfo
format is completely different on x86, x86_64 and we haven't heard of any
x86 app breakage because of this issue. Grouping these fields will
result in more or less common format on all architectures (ia64, x86 and
x86_64) and will cause less confusion.

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.

Only display physical id/siblings when there are siblings or dual core.
In 2.6.11 I accidentially broke it and it was always displaying these
fields But for compatibility to all these /proc parsers around it is better
to do it in the old way again.

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!
